Baffle type slide machine

Abstract

The invention relates to a sliding vane machine, in particular to a baffle type sliding vane machine in which baffles are arranged at both ends of a cylindrical rotor in the shape of a coil. The baffle type sliding vane machine, the sliding vane machine includes a stator and a sliding vane rotor. The two ends of the cylindrical rotor are provided with baffles that rotate together to form a baffle type sliding vane rotor. The inner wall surface of the stator is in contact with the sliding vane to form a rotating sealing section sandwiched between the two Between the two baffles, the two baffles respectively form a rotary seal with the protruding cylinder inner wall surface at both ends of the stator, thus forming a single-stage baffle type sliding vane machine. It solves the problem of large leakage of the existing sliding vane machine, and unexpectedly solves the problem of the suspended shear force of the sliding vane. It can improve energy efficiency, improve the reliability and durability of the baffle-type sliding vane machine, can be used as an expander, has a wide speed range, and can be made into a multi-stage baffle with a larger output power than a single-stage baffle-type sliding vane machine The sliding vane machine can be used not only as a hydraulic pump, a compressor, but also as a hydraulic motor and an expander, which is conducive to increasing production and reducing costs and selling prices.

Description

technical field [0001] The invention relates to a sliding vane machine, in particular to a baffle type sliding vane machine in which baffles are arranged at both ends of a cylindrical rotor in the shape of a coil. [0002] technical background [0003] Prior art slide vane machines, typically used as pumps or hydraulic motors. The extension work of the slider is divided into centrifugal throwing out and spring preloading. The rotor of the slider is a cylinder, and the slider is also called a blade. It is usually made of non-metal such as plastic, and the suspension extension of the slider is less than its radial length. one-half of. The groove is also called the chute. There are only 1 or 2 cylinders. Each cylinder is divided into a suction chamber and a discharge chamber. Every time the rotor rotates, the working volume between two adjacent blades absorbs liquid and discharges liquid once. It is a single-acting vane pump, and the working volume between two adjacent blades ...

AI Technical Summary

Problems solved by technology

When working, the sliding piece should protrude from the groove, and it is suspended without support. Under the action of pressure and sliding contact friction between the sliding piece and the inner wall of the stator, the protruding sliding piece is no longer parallel to the inner plane of the groove, and it will be in contact with the inner surface of the groove. The groove opening forms a seesaw to generate a suspended shear force, which will increase with the extension of the slide and the force. The suspended shear will hinder the speed of the slide and accelerate the wear of the slide. It will cut off the slide, and also limit the maximum speed of the rotor and the extension of the slide

[0013] 3. The slide machine is more expensive than other models

The reason is that in addition to requiring a reasonable high cost of precision machining, the leakage cannot be solved, the cost performance is low, the application is limited, it is difficult to sell, and the natural output does not increase, which leads to high costs and a vicious circle, which is the main reason for the high price.

[0014] 4. The prior art sliding vane machine usually has only 1 or 2 cylinders, and the power of the single machine is relatively small

[0015] 5. The prior art sliding vane machine is used in a single stage and cannot be used in multiple stages. It is usually used as a pump and has a single purpose.

[0016] In order to solve the problem of large leakage, people have also proposed solutions, such as patent application number CN201810831776.6, a sliding vane air compressor with enhanced sealing structure, but it only solves the problem of directly injecting lubricating oil into the cylinder block through several small hole channels Internally, an oil film layer is formed between the rotor and the vane and between two vanes
