Description

Crankshaft structure and integrated swing rotor type pump body assembly

Technical Field

Background

Rotary compressors are widely used in the temperature conditioning industry, such as air conditioning, refrigerators, heat pumps, etc., with their excellent combination of properties in the current refrigeration industry. The rotary compressor in the prior art mainly includes a wobble rotor type compressor and a rolling rotor type compressor.

Rolling rotor compressors have the advantage of low cost, but their sliding vane cannot be fully and reliably contact sealed with the outer diameter of the rolling rotor (piston), resulting in increased leakage in the compressor. And under the condition of the same outer diameter size, the spring is used as the initial starting pressure, the spring structure occupies the radial size, so that the radial size of the compressor is increased, meanwhile, the structure of the cylinder is complex, the contact surface between the sliding vane groove of the cylinder and the sliding vane is greatly reduced due to the spring hole, and the sliding vane groove is more easily worn.

The swing rotor type compressor comprises a piston and sliding vane integrated structure and a fixed sliding vane structure. The piston and sliding vane integrated structure is that the sliding vane and the piston are integrated into a swinging rotor, and the fixed sliding vane type structure is that the sliding vane and the piston are hinged. The piston slide plate integrated structure has better sealing performance relative to the fixed slide plate type structure. However, the piston slide vane integrated structure is sliding friction among all parts in the pump body in the swing operation process, the inside of the pump body is easy to wear, and the traditional swing rotor compressor is used for exhausting through an exhaust valve, so that the exhaust valve plate is extremely easy to wear.
