Description
本发明涉及换热系统技术领域,具体而言,涉及一种压缩机、换热设备和压缩机的运行方法。The invention relates to the technical field of heat exchange systems, in particular to a compressor, a heat exchange device and a method for operating a compressor.

The motor drives the crankshaft to output power, and the crankshaft drives the piston to reciprocate in the cylinder to compress the gas or the liquid to perform work for the purpose of compressing the gas or the liquid.
传统的活塞式压缩机存在诸多缺陷:由于吸气阀片和排气阀片的存在,导致吸、排气阻力加大,同时增加了吸排气噪音;压缩机的气缸所受侧向力较大,侧向力做无用功,降低压缩机效率;曲轴带动活塞往复运动,偏心质量较大,导致压缩机振动大;压缩机通过曲柄连杆机构带动一个或多个活塞工作,结构复杂;曲轴及活塞受到的侧向力较大,活塞容易磨损,导致活塞密封性降低。且现有的压缩机由于存在余隙容积,泄漏大等原因,容积效率低,且很难有进一步提高。The traditional piston compressor has many defects: due to the presence of the suction valve piece and the exhaust valve piece, the suction and exhaust resistance are increased, and the suction and exhaust noise is increased; the cylinder of the compressor is subjected to the lateral force. Large, lateral force does useless work, reducing compressor efficiency; crankshaft drives the piston to reciprocate, the eccentric mass is large, resulting in large compressor vibration; the compressor drives one or more pistons through the crank linkage mechanism, the structure is complex; the crankshaft and The piston is subjected to a large lateral force, and the piston is easily worn, resulting in a decrease in piston sealing performance. Moreover, the existing compressor has a volumetric efficiency due to the existence of a clearance volume, a large leak, and the like, and it is difficult to further improve.
不仅如此,活塞式压缩机中的偏心部的质心做圆周运动产生一个大小不变、方向改变的离心力,该离心力导致压缩机振动加剧。Moreover, the circular motion of the centroid of the eccentric portion of the piston compressor produces a centrifugal force of constant size and direction, which causes the vibration of the compressor to be intensified.

In addition, a method of operating the compressor is also provided.
如图2至图23所示,压缩机包括上法兰50、下法兰60、至少两个气缸20、转轴组件和活塞组件30,至少两个气缸20夹设在上法兰50与下法兰60之间,任意相邻两个气缸20均彼此独立工作,转轴组件依次穿过上法兰50、气缸20和下法兰60,转轴组件包括与至少两个气缸20中的每个气缸20一一对应设置的子转轴10,子转轴10的轴心与该子转轴10对应的气缸20的轴心偏心设置且偏心距离固定,活塞组件30具有与每个气缸20一一对应的变容积腔31,活塞组件30可枢转地设置在气缸20内,且至少一个子转轴10与活塞组件30驱动连接以改变变容积腔31的容积。其中,上法兰50通过第二紧固件70与靠近上法兰50一侧的气缸20固定,下法兰60通过第三紧固件80与靠近下法兰60一侧的气缸20固定。
As shown in FIG. 2 to FIG. 23, the compressor includes an upper flange 50, a lower flange 60, at least two cylinders 20, a rotating shaft assembly and a piston assembly 30, and at least two cylinders 20 are sandwiched between the upper flange 50 and the lower method. Between the waves 60, any two adjacent cylinders 20 operate independently of each other, the shaft assembly sequentially passes through the upper flange 50, the cylinder 20 and the lower flange 60, and the shaft assembly includes and each of the at least two cylinders 20 The spindle shaft 10 is disposed correspondingly, the axis of the sub-rotating shaft 10 is eccentrically disposed with the axis of the cylinder 20 corresponding to the sub-rotating shaft 10, and the eccentric distance is fixed, and the piston assembly 30 has a variable volume chamber corresponding to each cylinder 20 in one-to-one correspondence. 31. The piston assembly 30 is pivotally disposed within the cylinder 20 and at least one sub-rotor 10 is drivingly coupled to the piston assembly 30 to vary the volume of the variable volume chamber 31. The upper flange 50 is fixed to the cylinder 20 on the side close to the upper flange 50 by the second fastener 70, and the lower flange 60 is fixed to the cylinder 20 on the side close to the lower flange 60 by the third fastener 80.
优选地,第二紧固件70和/或第三紧固件80为螺钉或螺栓。Preferably, the second fastener 70 and/or the third fastener 80 are screws or bolts.
优选地,上法兰50上设置有供第二紧固件70穿设的第一泵体螺钉孔。下法兰60上设置有四个供第三紧固件80穿设的第二泵体螺钉孔。Preferably, the upper flange 50 is provided with a first pump body screw hole through which the second fastener 70 is inserted. The lower flange 60 is provided with four second pump body screw holes for the third fastener 80 to pass through.
需要说明的是,上法兰50上的第一泵体螺钉孔的中心与上法兰50的质心存在一定偏心距e。此偏心距决定了靠近上法兰50一侧的气缸20的排量,当气缸20旋转一周,气体排量为V=2*2e*S,其中S为活塞主体结构横截面积。It should be noted that the center of the first pump body screw hole on the upper flange 50 and the center of the upper flange 50 have a certain eccentricity e. This eccentricity determines the displacement of the cylinder 20 near the upper flange 50. When the cylinder 20 rotates one revolution, the gas displacement is V = 2 * 2e * S, where S is the cross-sectional area of the piston body structure.
任意相邻两个气缸20之间均彼此独立工作,通过将转轴组件中的子转轴10的轴心与该子转轴10对应的气缸20的轴心偏心设置且将偏心距离固定,从而使子转轴10和气缸20在运动过程中绕各自轴心旋转,且质心位置不变,因而使得活塞组件30在气缸内运动时,能够稳定且连续地转动,有效缓解了压缩机的振动,并保证变容积腔31的容积变化具有规律、减小了余隙容积,从而提高了压缩机的运行稳定性,进而提高了换热设备的工作可靠性。Any two adjacent cylinders 20 are operated independently of each other, and the sub-axis is fixed by eccentrically setting the axis of the sub-rotary shaft 10 in the rotating shaft assembly and the axis of the cylinder 20 corresponding to the sub-rotating shaft 10 and fixing the eccentric distance. 10 and the cylinder 20 rotate around their respective axes during the movement, and the position of the center of mass is constant, thereby enabling the piston assembly 30 to rotate stably and continuously during the movement of the cylinder, thereby effectively alleviating the vibration of the compressor and ensuring variable volume. The volume change of the cavity 31 has a regularity, and the clearance volume is reduced, thereby improving the operational stability of the compressor, thereby improving the operational reliability of the heat exchange device.
需要说明的是,相邻两个气缸20彼此同轴心设置。优选地,上法兰50的轴心与靠近上法兰50一侧设置的气缸20的轴心偏心设置。优选地,下法兰60的轴心与靠近下法兰60一侧设置的气缸20的轴心偏心设置。以上述方式安装的气缸20,能够保证气缸20与子转轴10或上法兰50的偏心距固定,从而使活塞组件30具有运动稳定性好的特点。It should be noted that the adjacent two cylinders 20 are disposed concentrically with each other. Preferably, the axis of the upper flange 50 is eccentric from the axis of the cylinder 20 disposed on the side close to the upper flange 50. Preferably, the axis of the lower flange 60 is eccentric from the axis of the cylinder 20 disposed on the side close to the lower flange 60. The cylinder 20 mounted in the above manner can ensure that the eccentricity of the cylinder 20 and the sub-rotary shaft 10 or the upper flange 50 is fixed, so that the piston assembly 30 has a characteristic of good motion stability.
本发明中的子转轴10与活塞组件30滑动连接,且变容积腔31的容积随子转轴10的转动而变化。由于本发明中的子转轴10与活塞组件30滑动连接,因而保证了活塞组件30的运动可靠性,有效避免活塞组件30运动卡死的问题,从而使变容积腔31的容积变化具有规律的特点。The sub-rotary shaft 10 in the present invention is slidably coupled to the piston assembly 30, and the volume of the variable volume chamber 31 varies with the rotation of the sub-rotary shaft 10. Since the sub-rotary shaft 10 of the present invention is slidably coupled with the piston assembly 30, the movement reliability of the piston assembly 30 is ensured, and the problem of the movement of the piston assembly 30 is effectively avoided, so that the volume change of the variable volume chamber 31 has regular characteristics. .
如图2、图10至图13、图17至图23所示,活塞组件30包括活塞套33和至少两个活塞32,活塞套33可枢转地设置在气缸20内,活塞32滑动设置在活塞套33内以形成变容积腔31,且变容积腔31位于活塞32的滑动方向上。可选地,活塞32的个数与气缸20的个数一致。As shown in FIGS. 2, 10 to 13, and 17 to 23, the piston assembly 30 includes a piston sleeve 33 and at least two pistons 32. The piston sleeve 33 is pivotally disposed within the cylinder 20, and the piston 32 is slidably disposed at The variable displacement chamber 31 is formed in the piston sleeve 33, and the variable volume chamber 31 is located in the sliding direction of the piston 32. Alternatively, the number of pistons 32 coincides with the number of cylinders 20.
在该具体实施例中,活塞组件30与子转轴10滑动配合,且随着子转轴10的转动,活塞组件30相对于子转轴10具有直线运动趋势,从而使转动变为局部的直线运动。由于活塞32与活塞套33滑动连接,因而在子转轴10的驱动下,有效避免活塞32运动卡死,从而保证了活塞32、子转轴10和活塞套33的运动可靠性,进而提高了压缩机的运行稳定性。In this particular embodiment, the piston assembly 30 is slidably engaged with the sub-rotary shaft 10, and as the sub-rotation shaft 10 rotates, the piston assembly 30 has a linear motion tendency with respect to the sub-rotation shaft 10, thereby causing the rotation to become a local linear motion. Since the piston 32 is slidably coupled with the piston sleeve 33, the movement of the piston 32 is effectively prevented from being driven by the driving of the sub-rotating shaft 10, thereby ensuring the reliability of the movement of the piston 32, the sub-rotating shaft 10 and the piston sleeve 33, thereby improving the compressor. Operational stability.
在图1至图23、图24所示的优选实施方式中,气缸20、子转轴10、活塞32各为两个,一个子转轴10作为主动轴穿过上法兰50伸入靠近上法兰50一侧的气缸20内,并与该气缸20内的活塞32运动连接;另一个子转轴10作为被动轴穿过下法兰60伸入靠近下法兰60一侧的气缸20内,并与该气缸20内的活塞32运动连接。由于活塞组件30、气缸20和子转轴10之间形成十字滑块机构,因而使活塞组件30与气缸20的运动稳定且连续,并保证变容积腔31的容积变化具有规律,从而保证了压缩机的运行稳定性,进而提高了换热设备的工作可靠性。
In the preferred embodiment shown in FIG. 1 to FIG. 23 and FIG. 24, the cylinder 20, the sub-rotating shaft 10, and the piston 32 are each two, and one sub-rotating shaft 10 as a driving shaft extends through the upper flange 50 into the upper flange. The cylinder 20 on one side of the 50 is movably connected to the piston 32 in the cylinder 20; the other sub-rotor 10 as a passive shaft extends through the lower flange 60 into the cylinder 20 near the side of the lower flange 60, and The piston 32 within the cylinder 20 is movably coupled. Since the cross slide mechanism is formed between the piston assembly 30, the cylinder 20 and the sub-rotation shaft 10, the movement of the piston assembly 30 and the cylinder 20 is stabilized and continuous, and the volume change of the variable volume chamber 31 is ensured to be regular, thereby ensuring the compressor. Operational stability, which in turn improves the operational reliability of the heat exchange equipment.
主动轴由电机驱动旋转,被动轴由主动轴间接驱动旋转。The drive shaft is driven to rotate by the motor, and the driven shaft is driven indirectly by the drive shaft.
本发明中的活塞32具有沿子转轴10的轴向贯通设置的滑移孔321,子转轴10穿过滑移孔321,与主动轴配合的活塞32在主动轴的驱动下随主动轴旋转并同时沿垂直于主动轴的轴线方向在活塞套33内往复滑动;与被动轴配合的活塞32,在活塞套33的驱动下随活塞套33旋转并驱动被动轴旋转,同时与被动轴配合的活塞32沿垂直于被动轴的轴线方向在活塞套33内往复滑动。由于使活塞32相对于子转轴10做直线运动而非旋转往复运动,因而有效降低了偏心质量,降低了子转轴10和活塞32受到的侧向力,从而降低了活塞32的磨损、提高了活塞32的密封性能。The piston 32 of the present invention has a sliding hole 321 disposed through the axial direction of the sub-rotating shaft 10, and the sub-rotating shaft 10 passes through the sliding hole 321, and the piston 32 engaged with the driving shaft rotates with the driving shaft under the driving of the driving shaft. At the same time, the piston 32 is reciprocally slid in the axial direction perpendicular to the driving shaft; the piston 32 engaged with the passive shaft rotates with the piston sleeve 33 under the driving of the piston sleeve 33 and drives the driven shaft to rotate, and the piston cooperates with the passive shaft. 32 reciprocally slides within the piston sleeve 33 in an axial direction perpendicular to the passive shaft. Since the piston 32 is linearly moved relative to the sub-rotating shaft 10 instead of rotating and reciprocating, the eccentric mass is effectively reduced, and the lateral forces received by the sub-rotary shaft 10 and the piston 32 are reduced, thereby reducing the wear of the piston 32 and improving the piston. 32 sealing performance.
对于上述的被动轴,也就是设置在靠近下法兰60一侧的气缸20内的子转轴10而言,活塞套33转动并带动活塞32转动,而靠近下法兰60一侧设置的活塞32会在活塞套33内滑动以改变相应的变容积腔31的容积,同时靠近下法兰60一侧的子转轴10在该活塞32的驱动作用下转动,从而使活塞套33和该子转轴10分别承受弯曲变形和扭转变形,降低了单个零件的整体变形,降低了对子转轴10的结构强度要求。For the above-mentioned passive shaft, that is, the sub-rotary shaft 10 disposed in the cylinder 20 on the side close to the lower flange 60, the piston sleeve 33 rotates and drives the piston 32 to rotate, and the piston 32 disposed on the side close to the lower flange 60 is provided. The piston sleeve 33 is slid to change the volume of the corresponding variable volume chamber 31, while the sub-rotary shaft 10 near the lower flange 60 side is rotated by the driving of the piston 32, thereby causing the piston sleeve 33 and the sub-rotating shaft 10 The bending deformation and the torsional deformation are respectively taken down, the overall deformation of the individual parts is reduced, and the structural strength requirement for the sub-rotating shaft 10 is lowered.
优选地,滑移孔321为长孔或腰形孔。Preferably, the sliding hole 321 is a long hole or a waist hole.
本发明中的活塞32呈柱形。优选地,活塞32呈圆柱形或非圆柱形。The piston 32 in the present invention has a cylindrical shape. Preferably, the piston 32 is cylindrical or non-cylindrical.
如图10和图11所示,活塞32具有沿活塞32的中垂面对称设置的一对弧形表面,弧形表面与气缸20的内表面适应性配合,且弧形表面的弧面曲率半径的二倍等于气缸20的内径。这样,可以使得排气过程中可实现零余隙容积。需要说明的是,当活塞32放置在活塞套33内时,活塞32的中垂面为活塞套33的轴向平面。As shown in FIGS. 10 and 11, the piston 32 has a pair of arcuate surfaces symmetrically disposed along the median plane of the piston 32, the arcuate surface being adaptively fitted to the inner surface of the cylinder 20, and the curvature of the curved surface of the curved surface Two times the radius is equal to the inner diameter of the cylinder 20. In this way, a zero clearance volume can be achieved during the exhaust process. It should be noted that when the piston 32 is placed in the piston sleeve 33, the vertical plane of the piston 32 is the axial plane of the piston sleeve 33.

The guiding hole 311 is at least two, and each guiding hole 311 is correspondingly disposed. A piston 32, the piston 32 is slidably disposed in the guide hole 311 to reciprocate linearly. Since the piston 32 is slidably disposed in the guiding hole 311, when the piston 32 moves left and right in the guiding hole 311, the volume of the variable volume chamber 31 can be continuously changed, thereby ensuring the suction and exhaust stability of the compressor.
为了防止活塞32在活塞套33内旋转,导向孔311在下法兰60处的正投影具有一对相平行的直线段,一对相平行的直线段为活塞套33的一对相平行的内壁面投影形成,活塞32具有与导向孔311的一对相平行的内壁面形状相适配且滑移配合的外型面。如上述结构配合的活塞32和活塞套33,能够使使活塞32在活塞套33内平稳滑动且保持密封效果。In order to prevent the piston 32 from rotating within the piston sleeve 33, the orthographic projection of the pilot hole 311 at the lower flange 60 has a pair of parallel straight segments, and a pair of parallel straight segments are a pair of parallel inner wall faces of the piston sleeve 33. The projection is formed, and the piston 32 has an outer surface that is adapted to the shape of the pair of parallel inner wall faces of the guide hole 311 and that is slip-fitted. The piston 32 and the piston sleeve 33, which are configured as described above, enable the piston 32 to smoothly slide in the piston sleeve 33 and maintain a sealing effect.
优选地,导向孔311在下法兰60处的正投影具有一对弧形线段,该一对弧形线段与一对相平行的直线段相连接以形成不规则的截面形状。
Preferably, the orthographic projection of the pilot hole 311 at the lower flange 60 has a pair of arcuate segments joined to a pair of parallel straight segments to form an irregular cross-sectional shape.
如图2所示,活塞套33的外周面与气缸20的内壁面形状相适配。从而使得活塞套33与气缸20之间、导向孔311与活塞32之间为大面密封,且整机密封均为大面密封,有利于减小泄漏。As shown in FIG. 2, the outer peripheral surface of the piston sleeve 33 is adapted to the shape of the inner wall surface of the cylinder 20. Therefore, the piston sleeve 33 and the cylinder 20, the pilot hole 311 and the piston 32 are sealed with a large face, and the whole machine seal is a large face seal, which is beneficial to reduce leakage.
如图5所示,活塞套33的朝向下法兰60一侧的第一止推面332与下法兰60的表面接触。从而使活塞套33与下法兰60可靠定位。As shown in FIG. 5, the first thrust surface 332 of the piston sleeve 33 facing the lower flange 60 side is in contact with the surface of the lower flange 60. Thereby, the piston sleeve 33 and the lower flange 60 are reliably positioned.
如图12和图13所示,在活塞套33中相邻两个导向孔311之间形成隔板34,隔板34上开设有用于连通相邻两个导向孔311的过油孔35。该过油孔35用于保证隔板34两侧的子转轴10能够顺利得到润滑油的润滑。As shown in FIG. 12 and FIG. 13, a partition plate 34 is formed between the adjacent two guide holes 311 in the piston sleeve 33, and the oil passage hole 35 for communicating the adjacent two guide holes 311 is formed in the partition plate 34. The oil passage hole 35 is for ensuring that the sub-rotary shaft 10 on both sides of the partition plate 34 can smoothly obtain lubrication of the lubricating oil.

如图6至图9所示,子转轴10具有与活塞组件30滑动配合的滑移段11,滑移段11位于子转轴10的靠近气缸20的一端,且滑移段11具有滑移配合面111。由于子转轴10通过滑移配合面111与活塞32的滑移孔321滑动配合,因而保证了二者的运动可靠性,有效避免二者卡死。As shown in FIGS. 6 to 9, the sub-rotation shaft 10 has a slip section 11 that is slidably engaged with the piston assembly 30, the slip section 11 is located at one end of the sub-rotary shaft 10 near the cylinder 20, and the slip section 11 has a slip fit surface. 111. Since the sub-rotating shaft 10 is slidably engaged with the sliding hole 321 of the piston 32 through the sliding mating surface 111, the motion reliability of the two is ensured, and the two are effectively prevented from being stuck.
特别是靠近下法兰60一侧设置的子转轴10,该子转轴10上的滑移配合面111与对应的活塞32的滑移孔321的孔壁面配合,以使活塞32驱动该子转轴10转动。In particular, the sub-rotating shaft 10 disposed on the side of the lower flange 60, the sliding mating surface 111 of the sub-rotating shaft 10 cooperates with the hole wall surface of the sliding hole 321 of the corresponding piston 32, so that the piston 32 drives the sub-rotating shaft 10 Turn.
优选地,滑移段11具有两个对称设置的滑移配合面111。由于滑移配合面111对称设置,因而使得两个滑移配合面111的受力更加均匀,保证了子转轴10与活塞32的运动可靠性。Preferably, the slip section 11 has two symmetrical arrangement of slip fit faces 111. Since the sliding mating faces 111 are symmetrically disposed, the forces of the two slip mating faces 111 are more uniform, and the reliability of the movement of the sub-rotating shaft 10 and the piston 32 is ensured.
如图6至图9所示,子转轴10具有与活塞组件30滑动配合的滑移段11,滑移段11位于子转轴10的靠近气缸20的一端,且滑移段11具有两个对称设置的滑移配合面111。As shown in FIGS. 6 to 9, the sub-rotation shaft 10 has a slip section 11 that is slidably engaged with the piston assembly 30, the slip section 11 is located at one end of the sub-rotary shaft 10 near the cylinder 20, and the slip section 11 has two symmetrical settings. The slip fit surface 111.
优选地,滑移配合面111与子转轴10的轴向平面相平行,滑移配合面111与活塞32的滑移孔321的内壁面在垂直于子转轴10的轴线方向上滑动配合。Preferably, the slip mating surface 111 is parallel to the axial plane of the sub-rotating shaft 10, and the slip mating surface 111 is slidably engaged with the inner wall surface of the sliding hole 321 of the piston 32 in the axial direction perpendicular to the sub-rotating shaft 10.
本发明中的子转轴10具有润滑油道13,润滑油道13的至少一部分为子转轴10的内部油道。由于润滑油道13的至少一部分内部油道,因而有效避免润滑油大量外泄,提高了润滑油的流动可靠性。The sub-rotary shaft 10 in the present invention has a lubricating oil passage 13, and at least a part of the lubricating oil passage 13 is an internal oil passage of the sub-rotating shaft 10. Due to at least a part of the internal oil passage of the lubricating oil passage 13, the lubricating oil is effectively prevented from leaking out a large amount, and the flow reliability of the lubricating oil is improved.
如图6至图9所示,在滑移配合面111处的润滑油道13为外部油道。由于滑移配合面111处的润滑油道13为外部油道,因而使得润滑油可以直接供给给滑移配合面111和活塞32,有效避免二者摩擦力过大而磨损,从而提高了二者的运动平滑性。As shown in FIGS. 6 to 9, the lubricating oil passage 13 at the slip fitting surface 111 is an outer oil passage. Since the lubricating oil passage 13 at the slip fitting surface 111 is an external oil passage, the lubricating oil can be directly supplied to the sliding mating surface 111 and the piston 32, thereby effectively avoiding excessive friction and wear of the two, thereby improving the two. The smoothness of the movement.

The interior of the pump assembly 93 is disposed. The pump body assembly 93 of the compressor includes the upper flange 50, the lower flange 60, the cylinder 20, the shaft assembly, and the piston assembly 30 described above.
优选地,上述各部件通过焊接、热套、或冷压的方式连接。Preferably, the above components are joined by welding, hot jacketing, or cold pressing.

Thereby the assembly of the pump body assembly 93 is completed, as shown in FIG.
优选地,本发明中的压缩机不设置吸气阀片,从而能够有效减少吸气阻力,提高压缩机的压缩效率。Preferably, the compressor of the present invention is not provided with an intake valve piece, so that the suction resistance can be effectively reduced and the compression efficiency of the compressor can be improved.
需要说明的是,在该具体实施方式中,在一个活塞32完成一周的运动时,会吸气、排气两次,从而使压缩机具有压缩效率高的特点。与同排量的单缸滚子压缩机相比,由于将原来的一次压缩分为两次压缩,因而本发明中的压缩机的力矩波动相对较小,运行时,具有排气阻力小,有效消除了排气噪音。
It should be noted that, in this embodiment, when one piston 32 completes one-week movement, it inhales and exhausts twice, so that the compressor has a high compression efficiency. Compared with the single-displacement single-cylinder roller compressor, since the original primary compression is divided into two compressions, the torque fluctuation of the compressor in the present invention is relatively small, and the exhaust resistance is small and effective during operation. Eliminates exhaust noise.
具体而言,如图17至图23所示,本发明中的每个气缸20的气缸壁具有压缩进气口21和第一压缩排气口22,当活塞组件30处于进气位置时,压缩进气口21与变容积腔31导通;当活塞组件30处于排气位置时,变容积腔31与第一压缩排气口22导通。Specifically, as shown in FIGS. 17 to 23, the cylinder wall of each cylinder 20 in the present invention has a compression intake port 21 and a first compression exhaust port 22, which is compressed when the piston assembly 30 is in the intake position. The intake port 21 is electrically connected to the variable volume chamber 31; when the piston assembly 30 is in the exhaust position, the variable volume chamber 31 is electrically connected to the first compressed exhaust port 22.
优选地,气缸壁的内壁面具有压缩进气缓冲槽23,压缩进气缓冲槽23与压缩进气口21连通(请参考图17至图23)。由于设置有压缩进气缓冲槽23,因而在该处会蓄存有大量的气体,以使变容积腔31能够饱满吸气,从而使压缩机能够足量吸气,并在吸气不足时,能够及时供给蓄存气体给变容积腔31,以保证压缩机的压缩效率。Preferably, the inner wall surface of the cylinder wall has a compressed intake buffer groove 23, and the compressed intake buffer groove 23 communicates with the compressed intake port 21 (please refer to FIGS. 17 to 23). Since the compressed air intake buffer tank 23 is provided, a large amount of gas is stored therein, so that the variable volume chamber 31 can be fully inhaled, so that the compressor can sufficiently inhale, and when the air intake is insufficient, The storage gas can be supplied to the variable volume chamber 31 in time to ensure the compression efficiency of the compressor.
具体而言,压缩进气缓冲槽23在气缸20的径向平面内呈弧形段,且压缩进气缓冲槽23由压缩进气口21处向第一压缩排气口22所在一侧延伸,且压缩进气缓冲槽23的延伸方向与活塞组件30的转动方向同向。Specifically, the compressed intake buffer groove 23 has an arc segment in the radial plane of the cylinder 20, and the compressed intake buffer groove 23 extends from the compressed intake port 21 toward the side of the first compression exhaust port 22, And the direction in which the compressed intake buffer groove 23 extends is in the same direction as the rotational direction of the piston assembly 30.
本发明中的每个气缸20的气缸壁具有第二压缩排气口24,第二压缩排气口24位于压缩进气口21与第一压缩排气口22之间,且在活塞组件30转动的过程中,在活塞组件30内的部分气体先经过第二压缩排气口24的泄压后再由第一压缩排气口22全部排出。由于仅设置有两条排气通路,一条是经第一压缩排气口22排气,另一条是经第二压缩排气口24排气,因而减少了气体泄漏,提高了气缸20的密封面积。The cylinder wall of each cylinder 20 in the present invention has a second compressed exhaust port 24, and the second compressed exhaust port 24 is located between the compressed intake port 21 and the first compressed exhaust port 22, and is rotated at the piston assembly 30. During the process, part of the gas in the piston assembly 30 is first discharged through the second compressed exhaust port 24 and then discharged from the first compressed exhaust port 22. Since only two exhaust passages are provided, one is exhausted through the first compressed exhaust port 22, and the other is exhausted through the second compressed exhaust port 24, thereby reducing gas leakage and increasing the sealing area of the cylinder 20. .
优选地,压缩机还包括排气阀组件40,排气阀组件40设置在第二压缩排气口24处。由于在第二压缩排气口24处设置有排气阀组件40,因而有效避免变容积腔31内气体大量泄漏,保证了变容积腔31的压缩效率。Preferably, the compressor further includes an exhaust valve assembly 40 disposed at the second compressed exhaust port 24. Since the exhaust valve assembly 40 is provided at the second compression exhaust port 24, a large amount of gas leakage in the variable volume chamber 31 is effectively prevented, and the compression efficiency of the variable volume chamber 31 is ensured.
在图5所示的优选实施方式中,气缸壁的外壁上开设有容纳槽25,第二压缩排气口24贯通容纳槽25的槽底,排气阀组件40设置在容纳槽25内。由于设置有用于容纳排气阀组件40的容纳槽25,因而减少了排气阀组件40的占用空间,使部件合理设置,从而提高了气缸20的空间利用率。In the preferred embodiment shown in FIG. 5, the outer wall of the cylinder wall is provided with a receiving groove 25, and the second compressed exhaust port 24 penetrates the groove bottom of the receiving groove 25, and the exhaust valve assembly 40 is disposed in the receiving groove 25. Since the accommodating groove 25 for accommodating the vent valve assembly 40 is provided, the space occupied by the vent valve assembly 40 is reduced, and the components are properly disposed, thereby increasing the space utilization of the cylinder 20.
具体而言,排气阀组件40包括排气阀片41和阀片挡板42,排气阀片41设置在容纳槽25内并遮挡第二压缩排气口24,阀片挡板42叠置在排气阀片41上。由于设置有阀片挡板42,因而有效避免排气阀片41过度开启,保证了气缸20的排气性能。Specifically, the exhaust valve assembly 40 includes an exhaust valve plate 41 and a valve flapper 42 disposed in the receiving groove 25 and blocking the second compressed exhaust port 24, and the valve flapper 42 is stacked On the exhaust valve piece 41. Since the valve flapper 42 is provided, the exhaust valve flap 41 is effectively prevented from being excessively opened, and the exhaust performance of the cylinder 20 is ensured.
优选地,排气阀片41和阀片挡板42通过第一紧固件43连接。进一步地,第一紧固件43是螺钉。Preferably, the exhaust valve flap 41 and the valve flapper 42 are connected by a first fastener 43. Further, the first fastener 43 is a screw.
需要说明的是,本发明中的排气阀组件40能够将变容积腔31与泵体组件93的外部空间隔开,为背压排气:即当变容积腔31与第二压缩排气口24连通时后,变容积腔31的压力大于外部空间压力(排气压力)时,排气阀片41打开,开始排气;若连通后变容积腔31的压力仍低于排气压力,则此时排气阀片41不工作。此时,压缩机继续运转、压缩,直至变容积腔31与第一压缩排气口22连通,将变容积腔31内的气体压入外部空间,完成排气过程。第一压缩排气口22的排气方式为强制排气方式。It should be noted that the exhaust valve assembly 40 of the present invention can separate the variable volume chamber 31 from the external space of the pump body assembly 93, and is a back pressure exhaust gas: that is, when the variable volume chamber 31 and the second compressed exhaust port After 24 communication, when the pressure of the variable volume chamber 31 is greater than the external space pressure (exhaust pressure), the exhaust valve piece 41 is opened to start the exhaust; if the pressure of the variable volume chamber 31 is still lower than the exhaust pressure after the communication, At this time, the exhaust valve piece 41 does not operate. At this time, the compressor continues to operate and compress until the variable volume chamber 31 communicates with the first compressed exhaust port 22, and the gas in the variable volume chamber 31 is pressed into the external space to complete the exhaust process. The exhaust mode of the first compression exhaust port 22 is a forced exhaust mode.
下面对压缩机的运行进行具体介绍,以逆时针转动为例:
The following is a detailed description of the operation of the compressor, taking counterclockwise rotation as an example:
如图24所示,本发明中的压缩机采用十字滑块机构原理设置。其中,子转轴10的轴心O1与气缸20的轴心O2偏心设置,而二者的偏心距固定为e,且二者分别绕各自的轴心旋转。活塞32相当于十字滑块机构中的滑块,活塞套33的轴心到活塞32的轴心的距离以及子转轴10的轴心到活塞32的轴心的距离分别相当于两根连杆l1、l2,这样就构成十字滑块原理的主体结构。As shown in Fig. 24, the compressor of the present invention is set using the principle of a cross slider mechanism. The axis O 1 of the sub-rotating shaft 10 is eccentrically disposed with the axis O 2 of the cylinder 20 , and the eccentricity of the two is fixed to e, and the two are respectively rotated about the respective axes. The piston 32 corresponds to a slider in the cross slider mechanism, the distance from the axial center of the piston sleeve 33 to the axial center of the piston 32 and the distance from the axial center of the sub-rotating shaft 10 to the axial center of the piston 32 correspond to two connecting rods, respectively. 1 , l 2 , this constitutes the main structure of the principle of the cross slider.
如图24所示,当上述结构的压缩机运行时,子转轴10绕子转轴10的轴心O1转动;气缸20绕气缸20的轴心O2转动,且子转轴10的轴心与气缸20的轴心偏心设置且偏心距离固定;活塞组件的活塞32在子转轴10的驱动下随子转轴10旋转并同时沿垂直于子转轴10的轴线方向在活塞组件的活塞套33内往复滑动。As shown in Fig. 24, when the compressor of the above configuration is operated, the sub-rotating shaft 10 is rotated about the axis O 1 of the sub-rotary shaft 10; the cylinder 20 is rotated about the axis O 2 of the cylinder 20, and the axis and the cylinder of the sub-rotating shaft 10 are The axial center of 20 is eccentrically disposed and the eccentric distance is fixed; the piston 32 of the piston assembly rotates with the sub-rotating shaft 10 under the driving of the sub-rotating shaft 10 while simultaneously reciprocatingly sliding in the piston sleeve 33 of the piston assembly in the direction perpendicular to the axis of the sub-rotating shaft 10.
如上述方法运行的压缩机,构成了十字滑块机构,该运行方法采用十字滑块机构原理,其中,活塞32作为滑块,子转轴10的滑移配合面111作为第一连杆l1、活塞套33的导向孔311作为第二连杆l2(请参考图24)。The compressor operated by the above method constitutes a cross slide mechanism, and the operation method adopts the principle of a cross slide mechanism, wherein the piston 32 serves as a slider, and the slip fit surface 111 of the sub-rotor shaft 10 serves as the first link l 1 , The guide hole 311 of the piston sleeve 33 serves as a second link 12 (refer to Fig. 24).
具体而言,子转轴10的轴心O1相当于第一连杆l1的旋转中心,气缸20的轴心O2相当于第二连杆l2的旋转中心;子转轴10的滑移配合面111相当于第一连杆l1,活塞套33的导向孔311相当于第二连杆l2;活塞32相当于滑块。导向孔311与滑移配合面111相互垂直;活塞32相对与导向孔311只能往复运动,活塞32相对于滑移配合面111只能往复运动。活塞32简化为质心后可以发现,其运行轨迹为圆周运动,该圆是以气缸20的轴心O2与子转轴10的轴心O1的连线为直径的圆。Specifically, the axis O 1 of the sub-rotating shaft 10 corresponds to the center of rotation of the first link 11 , the axis O 2 of the cylinder 20 corresponds to the center of rotation of the second link 12 ; and the slip fit of the sub-shaft 10 The surface 111 corresponds to the first link l 1 , the guide hole 311 of the piston sleeve 33 corresponds to the second link l 2 , and the piston 32 corresponds to the slider. The guiding hole 311 and the sliding mating surface 111 are perpendicular to each other; the piston 32 can only reciprocate relative to the guiding hole 311, and the piston 32 can only reciprocate relative to the sliding mating surface 111. The piston 32 can be simplified to find the centroid, which running track is a circular motion, the circular cylinder axis O is 20 in the shaft 2 and the sub line connecting the axis O 10 is a circular diameter.
当第二连杆l2作圆周运动时,滑块可以沿第二连杆l2往复运动;同时,滑块可以沿第一连杆l1往复运动。第一连杆l1和第二连杆l2始终保持垂直,使得滑块沿第一连杆l1往复运动方向与滑块沿第二连杆l2往复运动方向相互垂直。第一连杆l1和第二连杆l2及活塞32的相对运动关系,形成十字滑块机构原理。When the second link 12 moves in a circular motion, the slider can reciprocate along the second link 12 ; at the same time, the slider can reciprocate along the first link 11 . The first link and the second link l 1 l 2 remain vertically, so that the slider along the first link l 1 reciprocates along the direction perpendicular to the second slider link l 2 reciprocating direction. The relative motion relationship between the first link l 1 and the second link l 2 and the piston 32 forms the principle of the cross slider mechanism.
在该运动方法下,滑块作圆周运动,其角速度与第一连杆l1和第二连杆l2的转动速度相等。滑块运行轨迹为圆。该圆以第一连杆l1的旋转中心与第二连杆l2的旋转中心的中心距为直径。如图3所示的具体实施方式中,两个气缸20相差180度交错布置。两个活塞32在往复运动过程中形成四个变容积腔31。且这两个气缸20对应的两个分液器部件90交错180度布置。当然,也可以考虑将两个分液器部件90设置在同一侧,这样,两个气缸20也应无错位设置,完全重合叠置。Under the motion method, the slider performs a circular motion whose angular velocity is equal to the rotational speed of the first link 11 and the second link 12 . The slider runs in a circle. The circle has a diameter centered on the center of rotation of the first link l 1 and the center of rotation of the second link l 2 . In the embodiment shown in Figure 3, the two cylinders 20 are arranged 180 degrees apart. The two pistons 32 form four variable volume chambers 31 during the reciprocating motion. And the two dispenser parts 90 corresponding to the two cylinders 20 are arranged at an interval of 180 degrees. Of course, it is also conceivable to arrange the two dispenser parts 90 on the same side, so that the two cylinders 20 should also be arranged without any misalignment, completely overlapping.
如图16和图24所示,其中,靠近下法兰一侧的子转轴的轴心15与活塞套轴心333之间相差偏心距离e,活塞质心轨迹线呈圆形。
As shown in FIG. 16 and FIG. 24, the axis 15 of the sub-rotating shaft near the lower flange side and the piston sleeve axis 333 are separated by an eccentric distance e, and the piston centroid trajectory line is circular.
具体而言,电机组件92带动靠近上法兰50一侧的子转轴10转动,子转轴10的滑移配合面111驱动靠近上法兰50一侧的活塞32运动,活塞32带动活塞套33转动,进而带动靠近下法兰60一侧的活塞32转动,并促使靠近下法兰60一侧的子转轴10转动。在整个运动部件中,活塞套33仅作圆周运动,而活塞32一方面相对于子转轴10往复运动,同时又相对于活塞套33的导向孔311往复运动,而两个往复运动相互垂直且同时进行,从而使两个方向的往复运动构成十字滑块机构运动方式。这种类十字滑块机构的复合运动使活塞32相对于活塞套33作往复运动,该往复运动使活塞套33、气缸20与活塞32形成的腔体周期性的变大、缩小。而活塞32相对于气缸20作圆周运动,该圆周运动使活塞套33、气缸20与活塞32形成的变容积腔31周期性地与压缩进气口21、排气口连通。在以上两个相对运动的共同作用下,使压缩机可以完成吸气、压缩、排气的过程。在往复运动的过程中,活塞32的质心轨迹线为圆形,圆直径等于偏心量e,圆心在子转轴10的中心与活塞套33的中心连线的中点上。Specifically, the motor assembly 92 drives the sub-rotating shaft 10 near the upper flange 50 to rotate, and the sliding mating surface 111 of the sub-rotating shaft 10 drives the piston 32 on the side close to the upper flange 50, and the piston 32 drives the piston sleeve 33 to rotate. In turn, the piston 32 near the side of the lower flange 60 is rotated, and the sub-rotary shaft 10 near the side of the lower flange 60 is caused to rotate. In the entire moving part, the piston sleeve 33 only moves in a circular motion, and the piston 32 reciprocates on the one hand with respect to the sub-rotation shaft 10 while reciprocating relative to the guide hole 311 of the piston sleeve 33, and the two reciprocating motions are perpendicular to each other and simultaneously The reciprocating motion in both directions constitutes a motion of the cross slider mechanism. The combined motion of the cross-type slider mechanism reciprocates the piston 32 relative to the piston sleeve 33, which reciprocates the cavity formed by the piston sleeve 33, the cylinder 20 and the piston 32 periodically. The piston 32 is circumferentially moved relative to the cylinder 20, and the circular motion causes the variable displacement chamber 31 formed by the piston sleeve 33, the cylinder 20 and the piston 32 to periodically communicate with the compressed intake port 21 and the exhaust port. Under the combined action of the above two relative movements, the compressor can complete the process of inhaling, compressing and exhausting. During the reciprocating motion, the centroid trajectory of the piston 32 is circular, the diameter of the circle is equal to the eccentricity e, and the center of the circle is at the midpoint of the center of the sub-rotating shaft 10 and the center of the piston sleeve 33.
如图17至图23、图24所示,以一个变容积腔31为例,当变容积腔31与压缩进气口21连通时,开始吸气(请参考图17和图18);活塞套33继续带动活塞32、子转轴10顺时针旋转,当变容积腔31脱离压缩进气口21后,整个吸气结束,此时变容积腔31完全密封,开始压缩(请参考图18);继续旋转,气体不断压缩,当变容积腔31与第二压缩排气口24连通时,开始排气(请参考图19);继续旋转,不断压缩的同时不断排气,直到变容积腔31完全脱离第一压缩排气口22,完成整个吸气、压缩、排气过程(请参考图21至图23);随后变容积腔31旋转一定角度后再次连接压缩进气口21。压缩机的总排量为V=2*2*(2e*S)。As shown in FIG. 17 to FIG. 23 and FIG. 24, taking a variable volume chamber 31 as an example, when the variable volume chamber 31 is in communication with the compressed air inlet 21, air intake is started (please refer to FIG. 17 and FIG. 18); 33 continues to drive the piston 32 and the sub-rotating shaft 10 to rotate clockwise. When the variable volume chamber 31 is separated from the compressed air inlet 21, the entire inhalation ends, at which time the variable volume chamber 31 is completely sealed and begins to compress (please refer to FIG. 18); Rotating, the gas is continuously compressed, and when the variable volume chamber 31 is in communication with the second compressed exhaust port 24, the exhaust gas is started (please refer to FIG. 19); the rotation is continued, and the air is continuously compressed while continuously venting until the variable volume chamber 31 is completely separated. The first compressed exhaust port 22 completes the entire inhalation, compression, and exhaust process (please refer to FIG. 21 to FIG. 23); then the variable volume chamber 31 is rotated by a certain angle and then the compressed intake port 21 is connected again. The total displacement of the compressor is V = 2 * 2 * (2e * S).
此外,本发明中的压缩机还具有零余隙容积,高容积效率的优点,同时还能有效扩大压缩机的排量,并减小压缩机的力矩波动。In addition, the compressor of the present invention has the advantages of zero clearance volume and high volumetric efficiency, and at the same time, it can effectively expand the displacement of the compressor and reduce the torque fluctuation of the compressor.
