Abstract

A stationary vane type compressor comprises a rotor (1), a cylinder (2), a vane (3), a rotary column (4) and end closures. The rotor is eccentrically disposed in the cylinder. An axis of the rotor rotates about that of the cylinder. An outer surface of the rotor is tangent to an inner circumferential surface of the cylinder and cooperates with it. The outer end of the vane fixedly connects with the cylinder, and two lateral ends of it fixedly connect with two corresponding end closures respectively. A circular slot (5) is provided in the rotor. The rotary column is fitted in the circular slot and rotatably matches with it. A flat slide slot (6) is provided in the rotary column. The vane inserts into the slide slot and slidably matches with it. The cylinder, the vane and the end closures are all arranged in a stationary manner, so that the fit clearance and the relative movement between the cylinder and the vane or between the vane and the end closures are eliminated, and the friction loss and the leakage loss between them are reduced. On the other hand, the vane is not a movable member, so it is unnecessary to consider the dynamic balancing of the vane. That is to say, the dynamic balancing of the compressor can be simplified.

Description

说明书 静止叶片式压缩机  Instruction manual stationary vane compressor
[1] 技术领域  [1] Technical field
[2] 本发明涉及一种压缩机, 具体地说涉及一种叶片式压缩机, 更具体地说涉及 一种静止叶片式压缩机。  [2] The present invention relates to a compressor, and more particularly to a vane compressor, and more particularly to a stationary vane compressor.
[3] 背景技术 [3] Background Art
[4] 压缩机是各种气体压缩设备的关键装置, 在石油、 化工、 动力以及轻工等部 门均有大量使用。 在各种压缩机中, 有一类量大、 面广、 影响深的压缩机, 这 就是具有滑片结构特征的压缩机, 如滚动活塞式压缩机、 摆动转子式压缩机和 滑片式压缩机等等, 上述压缩机均属于旋转式压缩机的范畴, 与往复活塞式压 缩机相比, 它们具有体积小、 重量轻、 结构简单和动平衡性能好等优点, 故而 在空气压缩、 制冷以及空调领域得到非常广泛的应用。  [4] Compressors are the key components of various gas compression equipment and are used extensively in the petroleum, chemical, power and light industries sectors. Among various compressors, there is a large-volume, wide-faced, deep-impacting compressor, which is a compressor with a sliding structure, such as a rolling piston compressor, a oscillating rotor compressor, and a vane compressor. Etc., the above compressors belong to the category of rotary compressors. Compared with reciprocating piston compressors, they have the advantages of small size, light weight, simple structure and good dynamic balance performance. Therefore, in air compression, refrigeration and air conditioning. The field is very widely used.
[5] 但是, 传统滑片类旋转式压缩机存在有一个共性的弊端, 这就是它们均有一 个或多个做往返运动、 旋转运动或摆动运动的活动叶片。 由此就带来了两个问 题: 首先, 有运动就会存在配合间隙, 如叶片与气缸、 叶片与端盖之间就留有 配合间隙, 这不仅导致压缩机的内部泄漏损失, 而且会导致摩擦损失; 其次, 有运动就可能存在惯性力, 这是众所周知的事实, 如叶片的往复运动会造成往 复惯性力、 叶片的旋转运动会造成离心惯性力、 而叶片的摆动运动会造成摆动 惯性力, 这些惯性力的存在将导致压缩机的动平衡性变差, 并由此产生振动和 噪声。  [5] However, conventional slider-type rotary compressors have a common disadvantage, that is, they all have one or more moving blades that perform reciprocating, rotational or oscillating motion. This brings up two problems: First, there is a matching clearance when there is motion, such as a clearance gap between the blade and the cylinder, and between the blade and the end cap, which not only causes internal leakage loss of the compressor, but also causes Friction loss; Secondly, there may be inertial force when there is motion. It is a well-known fact that the reciprocating motion of the blade will cause the reciprocating inertial force, the rotational motion of the blade will cause the centrifugal inertial force, and the oscillating motion of the blade will cause the swinging inertial force. The presence of force will cause the dynamic balance of the compressor to deteriorate, and thereby generate vibration and noise.
[6] 发明内容  [6] Summary of the invention
[7] 针对传统滑片类旋转式压缩机存在的上述问题, 本发明提供一种静止叶片式 压缩机, 其目的在于有效解决叶片与气缸、 叶片与端盖之间的摩擦与泄漏问题 , 同吋还降低压缩机动平衡的复杂性。  [7] In view of the above problems of the conventional sliding type rotary compressor, the present invention provides a stationary vane type compressor, which aims to effectively solve the problem of friction and leakage between the vane and the cylinder, the vane and the end cap,吋 also reduces the complexity of the compressor dynamic balance.
[8] 为达到上述目的, 本发明釆用的技术方案是: 提供一种静止叶片式压缩机, 该压缩机包括一个转子、 一个气缸、 一个叶片、 一个转柱以及两个端盖; 转子 有一个圆柱形外表面, 气缸有一个圆孔形内孔面, 叶片呈扁平状, 转柱有一个 圆柱形外表面; 转子偏置在气缸内, 转子的轴线与气缸的轴线平行设置, 转子 的外表面与气缸的内孔面相切接触配合, 转子的轴线围绕气缸的轴线转动; 叶 片的外端与所述气缸密封连接, 叶片的两侧端分别与相对应的两个端盖密封连 接, 压缩机的叶片、 气缸和端盖均为静止布置, 亦即叶片为不运动的静止叶片 ; 在转子上开设有与转子轴线平行的圆弧槽, 转柱配装在该圆弧槽内并与之转 动配合; 在转柱上开设有一条与圆弧槽轴线平行的扁平状的滑槽, 叶片插设于 该滑槽内并与之滑动配合。 [8] In order to achieve the above object, the technical solution adopted by the present invention is: Provided a stationary vane type compressor, the compressor comprising a rotor, a cylinder, a blade, a rotating column and two end caps; a cylindrical outer surface, the cylinder has a circular hole-shaped inner hole surface, the blade is flat, and the rotating column has a a cylindrical outer surface; the rotor is biased in the cylinder, the axis of the rotor is disposed parallel to the axis of the cylinder, the outer surface of the rotor is in tangential contact with the inner bore surface of the cylinder, and the axis of the rotor rotates about the axis of the cylinder; the outer end of the blade The cylinders are sealingly connected, and the two ends of the blade are respectively sealedly connected with the corresponding two end caps, and the blades, the cylinders and the end caps of the compressor are all arranged in a stationary manner, that is, the blades are stationary blades that are not moving; An arc groove parallel to the axis of the rotor is disposed, and the rotating column is fitted in the arc groove and is rotated and matched with the rotating column; a flat sliding groove parallel to the axis of the circular groove is opened on the rotating column, and the blade is inserted In the chute and sliding fit with it.
本发明釆用叶片、 气缸和端盖为静止布局的结构方式, 一方面消除了它们之 间的配合间隙和相对运动, 结果减少了叶片与气缸、 叶片与端盖的摩擦损失和 泄漏损失; 另一方面, 由于叶片为静止状态而不再作为运动件, 故它无须进行 动平衡考虑, 换言之压缩机的动平衡得以简化。  The blade, the cylinder and the end cap of the invention have a static layout structure, on the one hand, the matching clearance and the relative movement between them are eliminated, and as a result, the friction loss and the leakage loss of the blade and the cylinder, the blade and the end cover are reduced; On the one hand, since the blade is in a stationary state and no longer acts as a moving member, it does not require dynamic balance considerations, in other words, the dynamic balance of the compressor is simplified.

In this embodiment, the stationary vane compressor includes a rotor 1, a cylinder 2, a vane 3, a rotating column 4, and two end caps (not shown); the rotor 1 has a cylindrical outer surface, The cylinder 2 has a circular hole-shaped inner hole surface, the blade 3 is flat, and the rotary column 4 has a cylindrical outer surface; the rotor 1 is biased in the cylinder 2, and the rotor axis 01 is disposed parallel to the cylinder axis 02, and the distance between the two axes That is, the eccentricity of the rotor 1 with respect to the cylinder 2, the rotor axis 01 rotates around the cylinder axis 02, and the outer surface of the rotor 1 is in tangent contact with the inner bore surface of the cylinder 2 (allowing for a motion gap or a film gap); the vane 3 and the cylinder The axis 02 is parallel, and the outer end thereof is sealingly connected with the cylinder 2. The optimal position of the blade 3 is arranged along the radial direction of the cross section of the cylinder 2, and the two ends of the blade 3 are respectively sealedly connected with the corresponding two end caps (Fig. It is not shown in the drawings); in particular, the sealed connection refers to a connection structure such as an embedded connection, an articulated connection, a screw connection, a rivet connection, a welded connection or an interference connection, an adhesive connection, or the like. Therefore, it is tightly sealed, and even elastic sealing bodies such as rubber, enamel, copper, paper mat, fiber, sealant, etc. can be laid at the joint. In the embodiment shown in the figure, the blade 3 is used for the sealing structure embedded in the cylinder 2; in this embodiment, the cylinder 2, the blade 3 and the end cover are all in a static layout, that is, they are not moving parts, this is The greatest feature of the invention. A circular arc groove 5 parallel to the rotor axis 01 is disposed on the rotor 1, and the circular arc groove axis 03 is fitted in the circular arc groove 5 and is rotatably engaged with the rotary shaft 4; a flat-shaped chute 6 in which the arcuate groove axis 03 is parallel, the vane 3 is inserted into the sliding groove 6 and slidably engaged with the sliding groove 6; in order to drive the rotor 1 to move, a rotating shaft 7 is coaxially arranged at a central portion of the rotor 1, and the rotating shaft 7 can directly drive the rotor 1 (not shown). The rotor can also be driven by the bearing 8. The bearing 8 can be either a rolling bearing or a sliding bearing. It should be noted that the rotating shaft 7 can be directly driven by the motor or by the motor. Indirect drive through a coupling or belt or gear; relative to the cylinder axis 02, the shaft 7 belongs to the eccentric journal structure; Figure 2 shows the upper and right positions of the rotor 1 relative to the stationary cylinder 2 during movement The working state diagram of the compressor in the four extreme positions of the position, the lower position and the left position, wherein the upper position refers to the position of the rotor axis 01 which is the closest position to the blade 3, that is, the length of the blade 3 entering the chute 6 is the longest. Lower position Refers to a rotor axis 01 from the position of the blade 3 is the furthest position, i.e. this length of 3 inches into the chute blade 6 reaches the minimum. It is not difficult to find that the rotor 1 rotates on the one hand about the cylinder axis 02 following the rotor axis 01. On the other hand, the rotor 1 also oscillates about the rotor axis 01, from the outer surface of the rotor 1, the inner bore surface of the cylinder 2, and the end caps on both sides. Forming a closed crescent-shaped space, the vane 3 divides the space into two working chamber suction chambers 9 and a compression chamber 10. As the rotor 1 rotates, the volume of the suction chamber 9 gradually increases, and the compression chamber 10 The volume is gradually reduced. Obviously, the suction port is connected to the suction chamber 9 in the end cover or the cylinder 2 or the same on the end cover and the cylinder 2, and the exhaust port is connected to the compression chamber 10, The compressor is constructed.

In parallel, for example, the two-cylinder machine can be made into a "day"-shaped layout, and the three-cylinder machine can be made into a "product" shape. The layout and the four-cylinder machine can be made into a "field" shape layout, and a five-cylinder or five-cylinder or higher can be made into a plum-like layout.
[17] 值得说明的是, 压缩机零部件的材料可以釆用金属材料也可以釆用非金属材料 , 其最佳做法是以金属如铸铁、 钢和合金钢、 粉末冶金等材料为本体, 然后在 本体的基础上镶、 嵌、 镀或覆盖一些弹性材料如塑料、 橡胶、 尼龙和各种纤维 等, 上述非金属材料可以充填碳粉、 石墨、 玻璃粉等耐磨耐热和减摩材料, 这 样就可以将压缩机制成无油润滑压缩机。 [17] It is worth noting that the material of the compressor parts can be made of either metallic materials or non-metallic materials. The best practice is to use materials such as cast iron, steel and alloy steel, powder metallurgy, etc. Embed, embed, plate or cover some elastic materials such as plastic, rubber, nylon and various fibers on the basis of the body. Etc., the above non-metallic materials can be filled with wear-resistant heat-resistant and friction-reducing materials such as carbon powder, graphite, and glass powder, so that the compressor can be made into an oil-free lubricating compressor.

Friction and leakage; on the other hand, since the blade 3 and the cylinder 2 are both in a stationary state without moving, they do not need to be balanced, in other words, the dynamic balance of the compressor is simplified.
[19] 最后, 必须指出的是, 本发明的静止叶片式压缩机的结构和工作原理可以移植 到各种流体泵和流体马达上, 如液压泵、 流量泵、 污水泵、 真空泵和液压马达 等等, 凡在上述装置中釆用本发明技术的均应该属于本发明的范畴及落在本发 明的保护范围之内。  [19] Finally, it must be pointed out that the structure and working principle of the stationary vane compressor of the present invention can be transplanted to various fluid pumps and fluid motors, such as hydraulic pumps, flow pumps, sewage pumps, vacuum pumps and hydraulic motors, etc. The use of the technology of the present invention in the above apparatus should fall within the scope of the present invention and fall within the scope of the present invention.
