Description

平动式旋转压缩装置 技术领域  Translational rotary compression device
本发明涉及在气体压缩、 流体输送和抽真空领域， 尤其涉及一种具有平动 活塞的旋转压縮机械。 说背景技术  This invention relates to the field of gas compression, fluid delivery and evacuation, and more particularly to a rotary compression machine having a translational piston. Background technology

At present, the rolling piston compression machine and the rotor compression machine are representative of the second generation of compression mechanical books, each having a crescent-shaped working cavity; the slit-shaped working chamber is separated into an expansion chamber and a compression chamber by a sliding plate; Or the translational piston) changes the volume of the expansion chamber and the compression chamber to achieve the suction (liquid) and exhaust (liquid) of the compression machine. However, there is a problem in both compression machines, that is, the slide plate protrudes into the working chamber to isolate the expansion chamber and the compression chamber by contacting the cylinder or the rotor (piston). This contact is a line contact, and the contact surface is high. Relative speed; These two factors determine that this type of compression machine can not withstand a large pressure difference, and the wear of the wearer is severe; in severe cases, the surface of the slide plate and the cylinder or the rotor (piston) are separated, causing the seal to fail.
大金工业株式会社于上世纪 90年代提出一种摇动压缩机械 （专利申请号 94191130. 6), 将活塞和滑板作成一体， 滑板穿过工作腔进入带导轨的缸体中， 将工作腔隔成膨胀腔和压缩腔。 导轨可沿缸体摇动， 滑板可在导轨中做往复运 动， 从而使得活塞在转子驱动下做摇动压縮。 该结构减少了磨损和泄漏， 在制 冷压縮行业取得了一些运用。 但是其活塞与滑板是一体的， 很难加工； 缸体内 侧需要预留滑板的往复运动空间， 使得缸体体积庞大， 容易变形； 由于结构限 制， 工作时机器产生的压缩热和摩擦热无法快速排出， 散热性能差。 发明内容 Daikin Industries Co., Ltd. proposed a rocking compression machine (patent application number 94191130. 6) in the 1990s. The piston and the slide plate are integrated. The slide plate passes through the working chamber and enters the cylinder with the guide rail to separate the working chamber. Expansion chamber and compression chamber. The guide rail can be rocked along the cylinder, and the slide can reciprocate in the guide rail, so that the piston is rocked and compressed under the driving of the rotor. This structure reduces wear and leakage and has achieved some use in the refrigeration compression industry. However, the piston and the sliding plate are integrated, which is difficult to process; the reciprocating space of the sliding plate needs to be reserved inside the cylinder body, so that the cylinder body is bulky and easily deformed; due to structural constraints, the compression heat and friction heat generated by the machine during operation cannot be fast.

The end of the sliding plate 6 is provided with a cylindrical protruding head 9, and the cylindrical protruding head 9 is movably received in the concave groove 10 to form a hinge structure of the sliding plate 6 and the inner wall of the cylinder block 1.
如图 2所示， 平动活塞 2包括内壁体 13和外壁体 14， 内壁体 13和外壁体 14通 过若干放射状设置的连接板 15连接， 连接板 15之间形成有散热通道 16， 并且平 动活塞 2设有两块具有平行面的连接板 15， 两块连接板 15之间形成有滑板槽 8。 滑板 6穿过工作腔 6、 7 入到滑板槽 8内， 滑板 6与滑板槽 8滑动联接， 滑板 6可以 在滑板槽 8内往复运动， 滑板 6将工作腔分隔成膨胀腔 6和压縮腔 7， 膨胀腔 6和压 缩腔 7上分别设有吸入口 11和排出口 12。  As shown in FIG. 2, the translational piston 2 includes an inner wall body 13 and an outer wall body 14. The inner wall body 13 and the outer wall body 14 are connected by a plurality of radially disposed connecting plates 15, and a heat dissipation passage 16 is formed between the connecting plates 15, and is translated. The piston 2 is provided with two connecting plates 15 having parallel faces, and a sliding groove 8 is formed between the two connecting plates 15. The slide plate 6 passes through the working chambers 6, 7 into the sliding groove 8, and the sliding plate 6 is slidably coupled with the sliding plate groove 8. The sliding plate 6 can reciprocate in the sliding groove 8. The sliding plate 6 divides the working chamber into the expansion chamber 6 and the compression chamber. 7. The expansion chamber 6 and the compression chamber 7 are respectively provided with a suction port 11 and a discharge port 12.
当偏心转子 4通过轴承 5驱动平动活塞 2沿顺时针 V方向运动时，由于滑板 6的 约束， 平动活 ¾2只能以缸体 1的圆心为中心做近似平动， 运动过程中膨胀腔 6的 容积逐渐变大，将外界的气（液）体吸入，压縮腔 7的容积逐渐变变小，将气（液） 体排除， 从而实现了吸气 （液） 和排气 （液）。 活塞上的散热通道 16能将压縮产 生的热量快速带出。 When the eccentric rotor 4 drives the translational piston 2 to move in the clockwise V direction through the bearing 5, due to the slide 6 Constraint, translational movement 3⁄42 can only approximate the center of the cylinder 1 as the center, the volume of the expansion chamber 6 gradually becomes larger during the movement, the external gas (liquid) body is sucked, and the volume of the compression chamber 7 gradually The change is small, and the gas (liquid) body is removed, thereby achieving suction (liquid) and exhaust (liquid). The heat dissipation passage 16 on the piston can quickly bring out the heat generated by the compression.
本发明的工作原理如图 3所示： 平动活塞 2的圆心为 o2， 缸体 1的圆心为 0l， 缸体 1的最高点为 A，滑板 6圆头的圆心为 O3 ;当机器运行时，平动活塞 2以 A 为 半径， 绕 做平动， 同时又以03圆心， 以 O3为半径作轻微摆动， 在这过程中， 滑板 6在滑板槽 8中做有规律的往复运动。 定义平动活塞 2的运动方向为顺时钟， 以其圆心 与滑板 6的中心线 O3重合时为一个工作周期的起始点， 旋转角
Figure imgf000007_0001
时， 工作腔处于上 一周期的吸排气 （液) 结束状态； 随着 的增加， 新形成的膨胀腔 6逐渐变大， 开始将外界的气 （液） 体吸入； 而上一周期的膨胀腔 6开始封闭， 转变成本工作 周期的压缩腔 7， 将气 （液） 体排出； 到《=360° 时， 一个周期的吸气 （液） 过 程和排气 （液） 过程完成。 如此循环， 实现了平动回转压缩机械的吸排气 （液) 过程。 The working principle of the invention is shown in Fig. 3: the center of the translational piston 2 is o 2 , the center of the cylinder 1 is 0l , the highest point of the cylinder 1 is A, and the center of the round head of the sliding plate 6 is O 3 ; run flat piston radius a 2, about to do translation, while the center 03 again to swing slightly O 3 as a radius, in this process, to make the slider 6 in a regular reciprocating slide groove 8 motion. It is defined that the moving direction of the translational piston 2 is a clockwise direction, and the center of rotation of the slider 6 coincides with the center line O 3 of the slider 6 as a starting point of a working cycle, the rotation angle
Figure imgf000007_0001
At the end, the working chamber is in the end state of the suction and exhaust (liquid) in the previous cycle; as the increase occurs, the newly formed expansion chamber 6 gradually becomes larger, and the external gas (liquid) body is started to be inhaled; and the expansion of the previous cycle The chamber 6 begins to close, transforming the compression chamber 7 of the duty cycle, and discharging the gas (liquid) body; to "=360°, one cycle of the suction (liquid) process and the exhaust (liquid) process are completed. In this cycle, the suction and exhaust (liquid) process of the translational rotary compression machine is realized.
