Problems solved by technology

However, this method increases the number of electronic components and increases production costs
[0003] The research on the double-cylinder variable-capacity rotary compressor is developing rapidly. Compared with the single-cylinder rotary compressor, the double-cylinder variable-capacity rotary compressor has the disadvantages of a large number of parts and high production costs.
Moreover, due to the addition of a set of compression components to the two-cylinder variable displacement rotary compressor, the friction loss increases
[0004] In response to this situation, the research on the single-cylinder double-vane rotary compressor is advancing. However, when the single-cylinder double-vane rotary compressor is in the high-capacity working mode, because only the first vane works, there is an increase in the clearance volume. Large, low volumetric efficiency and other issues

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] see Figure 1-Figure 7 , the double vane rotary compressor includes a motor assembly and a compression assembly arranged in the casing 10, the motor assembly includes a stator 18 and a rotor 17, the stator 18 is fixed on the inner wall of the casing 10, and the rotor 17 is fixed on the eccentric crankshaft 16 on. The compression assembly includes a piston 12 arranged in a cylinder 11. The cylinder 11 is provided with a first slide groove for accommodating a first slide 13.1 and a second slide groove for accommodating a second slide 13.2. The first slide groove and the second slide One slide cavity 84 communicates with the second slide cavity. Along the rotation direction of the eccentric crankshaft 16 , the angle between the first slide groove and the second slide groove is θ.

[0026] The rear part of the first slide groove is provided with a ...

Abstract

The invention relates to a double-slip-sheet rotary compressor, comprising a motor assembly and a compression assembly which are arranged in a housing, wherein the compression assembly comprises a piston disposed in an air cylinder; the air cylinder is provided with a first slip sheet groove for accommodating a first slip sheet and a second slip sheet groove for accommodating a second slip sheet; the first slip sheet groove is communicated with a first slip sheet cavity; the second slip sheet groove is communicated with a second slip sheet cavity; the second slip sheet cavity is communicated with a pressure-switch pipe and realizes volume change by switching the pressure of the second slip sheet cavity; the air cylinder is provided with a first exhaust notch and a second exhaust notch; a main bearing is provided with an upper exhaust hole; an auxiliary bearing is provided with a lower exhaust hole; an angle beta is formed by connecting lines between the center of the first exhaust notch and the center of the air cylinder and between the center of the second exhaust notch and the center of the air cylinder; and on basis of the center line of the first exhaust notch and in a counter-clockwise direction, the angle beta meets the following relationship. With the double-slip-sheet rotary compressor, clearance volume of a low-capacity working mode is effectively decreased; and volume efficiency of the compressor is improved.

Description

technical field [0001] The invention relates to a rotary compressor, in particular to a double-vane rotary compressor. Background technique [0002] In recent years, the method of changing the rotational speed of the rotary compressor by frequency conversion technology to realize the change of the displacement of the rotary compressor has become more and more popular. However, this method increases the number of electronic parts and increases production costs. [0003] The research on the double-cylinder variable-capacity rotary compressor is developing rapidly. Compared with the single-cylinder rotary compressor, the double-cylinder variable-capacity rotary compressor has the disadvantages of large number of parts and high production cost. Moreover, since a set of compression components is added to the double-cylinder variable displacement rotary compressor, the friction loss increases. [0004] In response to this situation, the research on the single-cylinder double-van...
