Problems solved by technology

[0003] At present, in the compressor pump body assembly, the gap between the cylinder vane groove and the vane needs to be extremely small to improve performance. It is best to only have a gap forming a layer of oil film, but the gap between the vane and the cylinder vane groove is too small. , easy to wear the slide and the cylinder slide groove
If it is intentionally enlarged in order to avoid wear and tear, the performance of the compressor will be limited, and at the same time, it is unavoidable that the sliding vanes will shift and fall off during operation, resulting in low cooling capacity and abnormal reliability of the compressor.

Embodiment Construction

[0023] See also Figure 1 to Figure 2 As shown, the existing compressor includes a pump body assembly. The pump body assembly includes a cylinder 1 and a sliding plate 2. The cylinder 1 is provided with a sliding plate groove 3, and the sliding plate 2 is slidably arranged in the sliding plate groove 3. When the compressor is running, the crankshaft drives the rollers to make a rotary motion. The sliding vane 2 closes to the roller and moves back and forth in the sliding vane groove 3 under the action of the spring, and cooperates with other pump body components to form a workable sealed environment.

[0024] In order to ensure the energy efficiency of the compressor, it is necessary to ensure that there is little gas leakage, that is, the roller and the sliding plate 2 are attached, and the gap between the sliding plate 2 and the cylinder 1 groove is as small as possible. When only the oil film is retained to ensure that the sliding plate 2 can operate, the sliding The leakage o...

Abstract

The invention provides a pump body assembly and a rotor compressor. The pump body assembly comprises an air cylinder (1) and a sliding sheet (2), the air cylinder (1) is provided with a sliding sheetgroove (3), and the sliding sheet (2) is slidably arranged in the sliding sheet groove (3); the sliding sheet (2) comprises a first sliding wall (4) and a second sliding wall (5), and the sliding sheet groove (3) comprises a first side wall (6) and a second side wall (7); the first sliding wall (4) and the first side wall (6) are opposite to each other, and the opposite faces of the first slidingwall (4) and the first side wall (6) have the same magnetism; and the second sliding wall (5) and the second side wall (7) are opposite to each other, and the opposite faces of the second sliding wall(5) and the second side wall (7) have the same magnetism. According to the pump body assembly, the clearance between the sliding sheet of the rotor compressor and the sliding sheet groove of the aircylinder can be effectively guaranteed, power consumption of the compressor is improved, and the performance and the quality of the compressor are improved.

Description

Technical field [0001] The invention belongs to the technical field of compressors, and specifically relates to a pump body assembly and a rotor compressor. Background technique [0002] At present, single-rotor compressors used in vehicle air conditioners, base station air conditioners, household small on-hook air conditioners, etc., are increasingly pursuing good performance and higher noise requirements. Quiet, highly adjustable and comfortable air conditioners with excellent performance have become the goal of air conditioner design. In order to meet the requirements of energy efficiency and strong adjustability, the operating frequency range of the core rotor compressor of the air conditioner is getting wider and the lowest. The operating frequency is getting smaller and smaller, and at the same time the cylinder diameter ratio of the compressor is getting larger and larger, and the requirements for matching between parts are getting higher and higher. [0003] At present, th...
