Air-conditioning compressor

Abstract

The invention provides an air conditioner compressor. A rotor is arranged in a compression chamber of a cylinder, and an upper sliding plate and a lower sliding plate are respectively connected to two radial ends of the rotor. The head of the upper slide plate is hinged with the inner wall of the cylinder, and its sliding part is slidably connected with the rotor. The head of the lower slide is hinged to the rotor, and its sliding part is slidingly connected to the inner wall of the cylinder. The upper slide is hinged to the inner wall of the cylinder and slides relative to the rotor. The lower slide is hinged to the rotor and connected to the guide rail to adapt to the change of the direction of the lower slide. The two compression chambers formed in the cylinder can realize the function of compressing the gas. At the same time, two pairs of air inlets and air outlets corresponding to the position are set on the cylinder inlet end cover and the cylinder exhaust end cover. The positions of the two air inlets correspond to the positions of the two compression chambers. Therefore, when the cylinder is working, the With one rotation, two exhausts and two suctions can be realized, so that the performance of the compressor with double slides is improved.

Problems solved by technology

[0003] Rolling rotor compressors usually include a rotor and a slide plate in structure. In terms of working principle, the slide plate is mainly attached to the surface of the rotor, and a working volume is formed between the outer surface of the rotor, the inner wall of the cylinder and the slide plate. In order to reduce gas The leakage from the compression chamber to the suction chamber requires the slide plate to form a certain pressure on the outer surface of the rolling rotor, which leads to greater wear and energy loss between them

In addition, due to the high relative motion speed between the slide plate and the cylinder, the rolling rotor compressor has serious mechanical friction, so the efficiency is low.

[0004] Screw compressors are generally used in workplaces with large cooling capacity. The pressure increase of screw compressors depends on the shape of the male and female rotors to seal the gas, so the processing technology is complex and the processing accuracy is high. The characteristics of the material are required high, resulting in higher cost

[0005] Although the scroll compressor is used in the field of small cooling capacity, its working principle is to seal the gas according to the profiles of the dynamic and static discs. Generally, the machining accuracy of the profiles is controlled at the μ level, and the detection is difficult. high manufacturing cost

[0006] The usual disadvantages of traditional compressors are severe friction and wear, large energy loss, large leakage, and low efficiency, making it difficult to meet the energy-saving operation requirements

Moreover, the traditional type of compressor has complicated process, high processing precision and high cost, which brings certain problems to industrial mass production.

Due to the large exhaust pulse and large rotation pulsation of the single-slide rotary compressor, the noise and vibration of the compressor are large, and the motor control is difficult.
