Description

流体机械、换热设备和流体机械的运行方法Fluid machinery, heat exchange equipment, and fluid machine operation methods 技术领域Technical field
本发明涉及换热系统技术领域,具体而言,涉及一种流体机械、换热设备和流体机械的运行方法。The invention relates to the technical field of heat exchange systems, in particular to a fluid machine, a heat exchange device and a method for operating a fluid machine.

现有技术中的活塞式压缩机的转轴与气缸在运动过程中,二者的质心的位置是变化的。电机组件驱动曲轴输出动力,由曲轴驱动活塞在气缸内往复运动来压缩气体或液体做功,以达到压缩气体或液体的目的。In the prior art, the position of the center of mass of the rotary shaft and the cylinder of the piston type compressor is varied during the movement. The motor assembly drives the crankshaft to output power, and the crankshaft drives the piston to reciprocate in the cylinder to compress gas or liquid to perform work for the purpose of compressing gas or 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.

如图2至图22所示,流体机械包括上法兰50、下法兰60、气缸20、转轴10、活塞套33、活塞套轴34和活塞32,其中,活塞套33可枢转地设置在气缸20内,活塞套轴34穿过上法兰50与活塞套33固定连接,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,转轴10,转轴10的轴心与气缸20的轴心偏心设置且偏心距离固定,转轴10依次穿过下法兰60和气缸20与活塞32滑动配合,在活塞套轴34的驱动作用下,活塞套33随活塞套轴34同步转动,以驱动活塞32在活塞套33内滑动以改变变容积腔31的容积,同时转轴10在活塞32的驱动作用下转动。其中,上法兰50通过第一紧固件70与气缸20固定,下法兰60通过第二紧固件80与气缸20固定。As shown in FIGS. 2 to 22, the fluid machine includes an upper flange 50, a lower flange 60, a cylinder 20, a rotating shaft 10, a piston sleeve 33, a piston sleeve shaft 34, and a piston 32, wherein the piston sleeve 33 is pivotally disposed In the cylinder 20, the piston sleeve shaft 34 is fixedly coupled to the piston sleeve 33 through the upper flange 50. The piston 32 is slidably disposed in the piston sleeve 33 to form a variable volume chamber 31, and the variable volume chamber 31 is located in the sliding direction of the piston 32. , the shaft 10, the axis of the shaft 10 is eccentrically arranged with the axis of the cylinder 20 and the eccentric distance is fixed, and the shaft 10 is sequentially slidably engaged with the piston 32 through the lower flange 60 and the cylinder 20, under the driving action of the sleeve shaft 34, The piston sleeve 33 rotates synchronously with the piston sleeve shaft 34 to drive the piston 32 to slide within the piston sleeve 33 to change the volume of the variable volume chamber 31 while the rotary shaft 10 is rotated by the driving of the piston 32. The upper flange 50 is fixed to the cylinder 20 by the first fastener 70, and the lower flange 60 is fixed to the cylinder 20 by the second fastener 80.
优选地,第一紧固件70和/或第二紧固件80为螺钉或螺栓。Preferably, the first fastener 70 and/or the second fastener 80 are screws or bolts.
通过将转轴10与气缸20的偏心距离固定,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32和活塞套33在气缸20内运动时,能够稳定且连续地转动,有效缓解了流体机械的振动,并保证变容积腔的容积变化具有规律、减小了余隙容积,从而提高了流体机械的运行稳定性,进而提高了换热设备的工作可靠性。By fixing the eccentric distance of the rotating shaft 10 and the cylinder 20, the rotating shaft 10 and the cylinder 20 are rotated about their respective axes during the movement, and the position of the center of mass is constant, thereby making the piston 32 and the piston sleeve 33 stable when moving in the cylinder 20. Continuously rotating, effectively alleviating the vibration of the fluid machine, ensuring that the volume change of the variable volume chamber is regular, reducing the clearance volume, thereby improving the operational stability of the fluid machine, thereby improving the reliability of the heat exchange equipment. Sex.
本发明中的流体机械通过活塞套轴34驱动活塞套33转动并带动活塞32转动,以使活塞32在活塞套33内滑动以改变变容积腔31的容积,同时转轴10在活塞32的驱动作用下转动,从而使活塞套33和转轴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,降低了对转轴10的结构强度要求,并能够有效减小活塞套33的端面与上法兰50的端面之间的泄漏。The fluid machine of the present invention drives the piston sleeve 33 to rotate by the piston sleeve shaft 34 and drives the piston 32 to rotate, so that the piston 32 slides within the piston sleeve 33 to change the volume of the variable volume chamber 31, while the shaft 10 is driven by the piston 32. The lower rotation causes the piston sleeve 33 and the rotating shaft 10 to undergo bending deformation and torsional deformation, respectively, which reduces the overall deformation of the single part, reduces the structural strength requirement of the rotating shaft 10, and can effectively reduce the end face and the upper method of the piston sleeve 33. Leakage between the ends of the blue 50.
需要说明的是,上法兰50和气缸20同轴心设置,且下法兰60的轴心与气缸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与转轴10或上法兰50的偏心距固定,从而使活塞套33具有运动稳定性好的特点。 It should be noted that the upper flange 50 and the cylinder 20 are disposed concentrically, and the axial center of the lower flange 60 is eccentric from the axial center of the cylinder 20. The cylinder 20 mounted in the above manner can ensure that the eccentricity of the cylinder 20 and the rotating shaft 10 or the upper flange 50 is fixed, so that the piston sleeve 33 has a characteristic of good motion stability.
在图2至图22所示的优选实施方式中,活塞32与转轴10滑动配合,且活塞32在活塞套33的驱动作用下,使转轴10的转动,活塞32相对于转轴10具有直线运动趋势。由于活塞32与活塞套33滑动连接,因而有效避免活塞32运动卡死,从而保证了活塞32、转轴10和活塞套33的运动可靠性,进而提高了流体机械的运行稳定性。In the preferred embodiment shown in FIG. 2 to FIG. 22, the piston 32 is slidably engaged with the rotating shaft 10, and the piston 32 is driven by the piston sleeve 33 to rotate the rotating shaft 10, and the piston 32 has a linear motion with respect to the rotating shaft 10. . Since the piston 32 is slidably coupled with the piston sleeve 33, the movement of the piston 32 is effectively prevented from being jammed, thereby ensuring the reliability of the movement of the piston 32, the rotating shaft 10 and the piston sleeve 33, thereby improving the operational stability of the fluid machine.
由于活塞32、活塞套33、气缸20和转轴10之间形成十字滑块机构,因而使活塞32、活塞套33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,从而保证了流体机械的运行稳定性,进而提高了换热设备的工作可靠性。Since the cross slider mechanism is formed between the piston 32, the piston sleeve 33, the cylinder 20 and the rotating shaft 10, the movement of the piston 32, the piston sleeve 33 and the cylinder 20 is stabilized and continuous, and the volume change of the variable volume chamber 31 is regular. Thereby ensuring the operational stability of the fluid machine, thereby improving the operational reliability of the heat exchange equipment.
本发明中的活塞32具有沿转轴10的轴向贯通设置的滑移孔321,转轴10穿过滑移孔321,转轴10在活塞32的驱动下随活塞套33和活塞32旋转,同时活塞32沿垂直于转轴10的轴线方向在活塞套33内往复滑动(请参考图10至图12、图16至图22)。由于使活塞32相对于转轴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。同时,保证了泵体组件93的运行稳定性和可靠性,并降低了流体机械的振动风险、简化了流体机械的结构。The piston 32 of the present invention has a sliding hole 321 which is disposed through the axial direction of the rotating shaft 10, and the rotating shaft 10 passes through the sliding hole 321, and the rotating shaft 10 rotates with the piston sleeve 33 and the piston 32 under the driving of the piston 32, and the piston 32 The reciprocating sliding in the piston sleeve 33 in the axial direction perpendicular to the rotating shaft 10 (please refer to Figs. 10 to 12, Figs. 16 to 22). Since the piston 32 is linearly moved relative to the rotating shaft 10 instead of rotating and reciprocating, the eccentric mass is effectively reduced, and the lateral force received by the rotating shaft 10 and the piston 32 is reduced, thereby reducing the wear of the piston 32 and improving the piston 32. Sealing performance. At the same time, the operational stability and reliability of the pump body assembly 93 are ensured, and the vibration risk of the fluid machine is reduced, and the structure of the fluid machine is simplified.
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.
在一个未图示的优选实施方式中,活塞32具有朝向转轴10一侧设置的滑移槽。不论是滑移槽还是滑移孔321,只要保证转轴10与活塞32相对可靠滑动即可。该滑移槽为直线式滑槽,且该滑移槽的延伸方向与转轴10的轴线垂直。In a preferred embodiment, not shown, the piston 32 has a sliding groove disposed toward the side of the rotating shaft 10. Regardless of the slip groove or the sliding hole 321 , it is only necessary to ensure that the rotating shaft 10 and the piston 32 slide relatively reliably. The slip groove is a linear chute, and the direction of the slip groove extends perpendicular to the axis of the rotating shaft 10.
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至图12、图16至图22,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。10 to 12 and 16 to 22, the piston 32 has a pair of arcuate surfaces symmetrically disposed along the center plane of the piston 32, the arcuate surface being adaptively fitted to the inner surface of the cylinder 20, and the curved surface The radius of curvature of the camber is equal to twice 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.
如图7至图9所示,活塞套33中具有沿活塞套33的径向贯通设置的导向孔311,活塞32滑动设置在导向孔311内以往复直线运动。由于活塞32滑动设置在导向孔311内,因而当活塞32在导向孔311内左右运动时,可以使变容积腔31的容积不断变化,从而保证流体机械的吸气、排气稳定性。As shown in FIGS. 7 to 9, the piston sleeve 33 has a guide hole 311 which is provided in the radial direction of the piston sleeve 33, and 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 fluid machine.
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18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. 18, 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2所示,转轴10具有与活塞32滑动配合的滑移段11,滑移段11位于转轴10的远离下法兰60的一端,且滑移段11具有滑移配合面111。由于转轴10通过滑移配合面111与活塞32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 FIG. 2, the rotating shaft 10 has a sliding section 11 that is slidably engaged with the piston 32. The sliding section 11 is located at one end of the rotating shaft 10 away from the lower flange 60, and the sliding section 11 has a sliding mating surface 111. Since the rotating shaft 10 is slidably engaged with 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.
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 slip mating faces 111 are symmetrically disposed, the forces of the two slip mating faces 111 are more uniform, which ensures the reliability of the movement of the rotating shaft 10 and the piston 32.
如图2所示,滑移配合面111与转轴10的轴向平面相平行,滑移配合面111与活塞32的滑移孔321的内壁面在垂直于转轴10的轴线方向上滑动配合。As shown in FIG. 2, the slip fitting surface 111 is parallel to the axial plane of the rotating shaft 10, and the sliding 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 rotating shaft 10.
本发明中的活塞套轴34具有沿活塞套轴34的轴向贯通设置的第一润滑油道341,转轴10具有与第一润滑油道341连通的第二润滑油道13,第二润滑油道13的至少一部分为转轴10的内部油道。由于第二润滑油道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 piston sleeve shaft 34 of the present invention has a first lubricating oil passage 341 penetratingly disposed in the axial direction of the piston sleeve shaft 34. The rotating shaft 10 has a second lubricating oil passage 13 communicating with the first lubricating oil passage 341, and the second lubricating oil. At least a portion of the track 13 is the internal oil passage of the rotating shaft 10. Due to at least a part of the internal oil passage of the second 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2所示,在滑移配合面111处的第二润滑油道13为外部油道。由于滑移配合面111处的第二润滑油道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 FIG. 2, the second lubricating oil passage 13 at the slip fitting surface 111 is an external oil passage. Since the second lubricating oil passage 13 at the slip matching 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 preventing the friction between the two from being excessively worn and thus improving. The smoothness of both sports.
如图2所示,转轴10具有通油孔14,内部油道通过通油孔14与外部油道连通。由于设置有通油孔14,因而使得内外油道可以顺利连通,且通过通油孔14处也可以向第二润滑油道13处注油,从而保证了第二润滑油道13的注油便捷性。As shown in FIG. 2, the rotating shaft 10 has an oil passage hole 14, and the internal oil passage communicates with the external oil passage through the oil passage hole 14. Since the oil passage hole 14 is provided, the inner and outer oil passages can be smoothly connected, and the oil passage hole 14 can also be injected into the second lubricating oil passage 13, thereby ensuring the convenience of oil filling of the second lubricating oil passage 13.
如图2和图23所示,本发明中的流体机械还包括支撑板61,支撑板61设置在下法兰60的远离气缸20一侧的端面上,且支撑板61与下法兰60同轴心设置并用于支撑转轴10,转轴10穿过下法兰60上的通孔支撑在支撑板61上,支撑板61具有用于支撑转轴10的第二止推面611。由于设置有支撑板61用于支撑转轴10,因而提高了各部件间的连接可靠性。As shown in FIGS. 2 and 23, the fluid machine of the present invention further includes a support plate 61 which is disposed on an end surface of the lower flange 60 on the side away from the cylinder 20, and the support plate 61 is coaxial with the lower flange 60. The core is disposed and supported for supporting the rotating shaft 10, and the rotating shaft 10 is supported on the supporting plate 61 through a through hole on the lower flange 60, and the supporting plate 61 has a second thrust surface 611 for supporting the rotating shaft 10. Since the support plate 61 is provided for supporting the rotary shaft 10, the connection reliability between the components is improved.

This amount determines the eccentric amount of the pump body assembly. After the piston sleeve 33 rotates for one week, the gas volume V=2*2e*S, Where S is the cross-sectional area of the main structure of the piston 32; the center of the threaded hole of the support disk coincides with the axis of the lower flange 60, and the support plate 61 is fixed with the third fastener 82.

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,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,且二者分别绕各自的轴心旋转。当转轴10转动时,活塞32相对转轴10和活塞套33直线滑动,以实现气体压缩,且活塞套33随着转轴10同步转动,而活塞32相对于气缸20的轴心在偏心距离e的范围内运行。活塞32的行程为2e,活塞32的横截面积为S,压缩机排量(也就是最大吸气容积)为V=2*(2e*S)。活塞32相当于十字滑块机构中的滑块,活塞—导向孔311、活塞32—转轴10的滑移配合面111分别充当十字滑块的两根连杆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. Wherein the shaft axis O 1 10 O 20 and the cylinder axis of the second eccentric is provided, and both fixed eccentricity, and both are rotated about their axes. When the rotating shaft 10 rotates, the piston 32 linearly slides relative to the rotating shaft 10 and the piston sleeve 33 to achieve gas compression, and the piston sleeve 33 rotates synchronously with the rotating shaft 10, and the piston 32 is in the range of the eccentric distance e with respect to the axial center of the cylinder 20. Running inside. The stroke of the piston 32 is 2e, the cross-sectional area of the piston 32 is S, and the displacement of the compressor (i.e., the maximum suction volume) is V = 2 * (2e * S). The piston 32 is equivalent to the slider in the cross slider mechanism, and the piston-guide hole 311 and the piston 32 - the sliding mating surface 111 of the rotating shaft 10 respectively serve as the two connecting rods l 1 and l 2 of the cross slider, thus forming a cross The main structure of the slider principle.
如图24所示,当上述结构的流体机械运行时,转轴10绕转轴10的轴心O1转动;气缸20绕气缸20的轴心O2转动,且转轴10的轴心与气缸20的轴心偏心设置且偏心距离固定;活塞32在转轴10的驱动下随转轴10旋转并同时沿垂直于转轴10的轴线方向在活塞套33内往复滑动。24, when the fluid machine of the above-described configuration is running, the rotary shaft 10 about the axis O 1 of the rotation shaft 10; a cylinder 20 of the cylinder axis O 2 20 to rotate about the cylinder axis and the axis 20 of the shaft 10 The center of the heart is eccentrically set and the eccentric distance is fixed; the piston 32 rotates with the rotating shaft 10 under the driving of the rotating shaft 10 and simultaneously reciprocates in the piston sleeve 33 in the axial direction perpendicular to the rotating shaft 10.
如上述方法运行的流体机械,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,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 fluid machine operated by the above method constitutes a cross slider mechanism, which adopts the principle of a cross slider mechanism, wherein the piston 32 serves as a slider, and the sliding mating surface 111 of the rotating shaft 10 serves as a first connecting rod l 1 and a piston. The guide hole 311 of the sleeve 33 serves as a second link 12 (refer to Fig. 24).
具体而言,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;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与转轴10的轴心O1的连线为直径的圆。Specifically, the axis O 1 of the rotating shaft 10 corresponds to the center of rotation of the first link 11 , and the axis O 2 of the cylinder 20 corresponds to the center of rotation of the second link 12 ; the slip fit surface 111 of the rotating shaft 10 Corresponding to the first link l 1 , the guide hole 311 of the piston sleeve 33 corresponds to the second link l 2 ; 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 and the axis O 2 of the shaft 10 of the wiring 1 is the diameter of the circle.
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15所示,其中,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。 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 . As shown in FIG. 15, the center axis 15 of the rotating shaft and the piston sleeve axis 333 are separated by an eccentric distance e, and the piston mass center trajectory line is circular.
如图6和图16所示,其中,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322呈圆形。As shown in FIG. 6 and FIG. 16 , the axial center 15 of the rotating shaft and the piston sleeve axial center 333 are separated by an eccentric distance e, and the piston centroid trajectory line 322 is circular.
活塞套33与转轴10偏心安装,活塞套轴34与电机组件92连接,电机组件92直接驱动活塞套33转动,属于活塞套驱动结构。活塞套33转动从而带动活塞32旋转,活塞32通过转轴支撑面进而带动转轴10旋转,活塞32、活塞套33、转轴10在旋转进程中,与其他泵体零件配合完成吸气、压缩和排气过程,一个循环周期为2π。转轴10顺时针转动。The piston sleeve 33 is eccentrically mounted with the rotating shaft 10, and the piston sleeve shaft 34 is connected to the motor assembly 92. The motor assembly 92 directly drives the piston sleeve 33 to rotate, which belongs to the piston sleeve driving structure. The piston sleeve 33 rotates to drive the piston 32 to rotate, and the piston 32 drives the rotating shaft 10 to rotate through the rotating shaft supporting surface. The piston 32, the piston sleeve 33 and the rotating shaft 10 cooperate with other pump parts to complete the suction, compression and exhaust during the rotation process. Process, one cycle is 2π. The shaft 10 rotates clockwise.
具体而言,电机组件92驱动活塞套轴34作旋转运动,导向孔311驱动活塞32做旋转运动,但是活塞32相对于活塞套33仅作往复运动;活塞32进一步带动转轴10作旋转运动,但是活塞32相对于转轴10同样仅作往复运动,此往复运动与活塞套33—活塞32的往复运动相互垂直。在往复运动过程中,整个泵体组件完成吸气、压缩、排气过程。在活塞运动过程中,活塞32-活塞套33、活塞32-转轴10这两个相互垂直的往复运动,使得活塞32的质心轨迹线为圆形,圆直径等于偏心量e,轴心在转轴10的中心与活塞套33的中心连线的中点上,旋转周期为π。Specifically, the motor assembly 92 drives the piston sleeve shaft 34 for rotational movement, and the pilot hole 311 drives the piston 32 to perform a rotational motion, but the piston 32 reciprocates only relative to the piston sleeve 33; the piston 32 further drives the shaft 10 for rotational movement, but The piston 32 also reciprocates only with respect to the rotating shaft 10, and this reciprocating motion is perpendicular to the reciprocating motion of the piston sleeve 33-piston 32. During the reciprocating motion, the entire pump body assembly completes the process of inhaling, compressing, and exhausting. During the movement of the piston, the two mutually perpendicular reciprocating motions of the piston 32-piston sleeve 33, the piston 32-the shaft 10, the center line of the piston 32 is circular, the diameter of the circle is equal to the amount of eccentricity e, and the axis is at the shaft 10 At the midpoint of the center of the piston sleeve 33, the rotation period is π.
活塞在活塞套33的导向孔311及气缸20的内圆面形成两个空腔,活塞套33旋转一周,两个空腔分别完成吸气、压缩、排气过程,不同点在于两个空腔吸排气压缩有180°相位差。以其中一个空腔为例说明泵体组件93的吸气、排气、压缩过程,如下:当空腔与压缩进气口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、转轴10顺时针旋转,当变容积腔31脱离压缩进气口21,整个吸气结束,此时空腔完全密封,开始压缩(请参考图19);继续旋转,气体不断压缩,当变容积腔31与压缩排气口22连通时,开始排气(请参考图20);继续旋转,不断压缩的同时不断排气,直到变容积腔31完全脱离压缩排气口22,完成整个吸气、压缩、排气过程(请参考图21和22);随后变容积腔31旋转一定角度后再次连接压缩进气口21,进入下一个循环。The piston forms two cavities in the guiding hole 311 of the piston sleeve 33 and the inner circular surface of the cylinder 20. The piston sleeve 33 rotates once, and the two cavities respectively perform the processes of inhaling, compressing and exhausting, and the difference lies in the two cavities. The suction and exhaust compression has a phase difference of 180°. Taking one of the cavities as an example to describe the process of inhaling, exhausting, and compressing the pump body assembly 93, as follows: when the cavity is in communication with the compressed air inlet 21, inhalation is started (please refer to FIG. 17 and FIG. 18); 33 continues to drive the piston 32, the shaft 10 rotates clockwise, when the variable volume chamber 31 is out of the compressed air inlet 21, the entire inhalation ends, at this time the cavity is completely sealed and begins to compress (please refer to Figure 19); continue to rotate, the gas is continuously compressed When the variable volume chamber 31 is in communication with the compressed exhaust port 22, the exhaust gas is started (please refer to FIG. 20); the rotation is continued, and the air is continuously exhausted while continuously compressing until the variable volume chamber 31 is completely separated from the compressed exhaust port 22, and is completed. The entire inhalation, compression, and exhaust process (please refer to Figures 21 and 22); then the variable volume chamber 31 is rotated by a certain angle and then connected to the compressed intake port 21 to enter the next cycle.
本发明中的泵体组件93为定压比泵体结构,两个变容积腔31为V=2*2e*S,S为活塞横截面积。The pump body assembly 93 in the present invention is a constant pressure ratio pump body structure, and the two variable volume chambers 31 are V=2*2e*S, and S is a piston cross-sectional area.
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。In addition, the compressor of the present invention also has the advantages of zero clearance volume and high volumetric efficiency.
需要强调的是,相对于转轴依次穿过上法兰50、气缸20和下法兰60的方案而言,本发明中的压缩机采用活塞套33带动活塞32旋转,活塞32带动转轴10旋转,活塞套33和转轴10分别承受弯曲变形和扭转变形,可以有效减小变形磨损;可以有效减小活塞套33的端面和上法兰50的端面之间的泄漏。该案重点在于,活塞套轴34与活塞套33是一体成型的。且上、下法兰偏轴心设置,以使转轴10和活塞套轴34偏心。It should be emphasized that, in the solution that the rotating shaft passes through the upper flange 50, the cylinder 20 and the lower flange 60 in sequence, the compressor of the present invention uses the piston sleeve 33 to drive the piston 32 to rotate, and the piston 32 drives the rotating shaft 10 to rotate. The piston sleeve 33 and the rotating shaft 10 respectively undergo bending deformation and torsional deformation, which can effectively reduce deformation wear; and can effectively reduce leakage between the end surface of the piston sleeve 33 and the end surface of the upper flange 50. The focus of this case is that the piston sleeve shaft 34 and the piston sleeve 33 are integrally formed. The upper and lower flanges are disposed off-axis to eccentrically rotate the shaft 10 and the sleeve shaft 34.
其他使用场合:该压缩机将吸、排气口交换位置,可以作为膨胀机使用。即,将压缩机的排气口作为膨胀机吸气口,通入高压气体,其他推动机构转动,膨胀后通过压缩机吸气口(膨胀机排气口)排出气体。 Other use occasions: The compressor exchanges the suction and exhaust ports and can be used as an expander. That is, the exhaust port of the compressor is used as an intake port of the expander, high-pressure gas is introduced, and other push mechanisms are rotated, and after being expanded, the gas is exhausted through the intake port of the compressor (expander port of the expander).
当流体机械为膨胀机时,气缸20的气缸壁具有膨胀排气口和第一膨胀进气口,当活塞套33处于进气位置时,膨胀排气口与变容积腔31导通;当活塞套33处于排气位置时,变容积腔31与第一膨胀进气口导通。当高压气体通过第一膨胀进气口进入变容积腔31内后,高压气体推动活塞套33旋转,活塞套33旋转以带动活塞32旋转,并同时使活塞32相对于活塞套33直线滑动,进而使活塞32带动转轴10旋转运动。通过将该转轴10与其他耗功设备连接,可以使转轴10输出做功。When the fluid machine is an expander, the cylinder wall of the cylinder 20 has an expansion exhaust port and a first expansion intake port, and when the piston sleeve 33 is in the intake position, the expansion exhaust port is electrically connected to the variable volume chamber 31; When the sleeve 33 is in the exhaust position, the variable volume chamber 31 is electrically connected to the first inflation inlet. When the high pressure gas enters the variable volume chamber 31 through the first expansion air inlet, the high pressure gas pushes the piston sleeve 33 to rotate, the piston sleeve 33 rotates to drive the piston 32 to rotate, and at the same time, the piston 32 linearly slides relative to the piston sleeve 33, thereby The piston 32 is caused to rotate the rotating shaft 10. By connecting the rotating shaft 10 with other power consuming devices, the rotating shaft 10 can be outputted for work.
优选地,气缸壁的内壁面具有膨胀排气缓冲槽,膨胀排气缓冲槽与膨胀排气口连通。Preferably, the inner wall surface of the cylinder wall has an expanded exhaust buffer tank that communicates with the expanded exhaust port.
