[0003] However, the rollers and vanes in existing compressors are limited by their structural design
When the compressor is running at high and low frequencies, the sliding vane is easily limited by its own running inertia and cannot follow the roller in time, so that the sliding vane is separated from the roller. Once there is a gap between the roller and the sliding vane, the compressor cylinder will The high-pressure chamber and the low-pressure chamber are connected in series, resulting in reduced energy efficiency of the compressor and abnormal mechanical noise

The invention discloses a pump body module. The pump body module comprises a roller and a slide piece; annular grooves distributed around the periphery of the roller are formed in the outer peripheralwall of the roller; clamping parts movably embedded in the annular grooves are arranged on the end surfaces, contacted with the roller, of the slide pieces; and the clamping parts are in sliding contact fit with the annular grooves in the peripheral direction of the roller, and are in stop contact fit with the annular grooves in the radial direction of the roller, so that the slide pieces are inrelative sliding fit with the roller in the peripheral direction of the roller. The pump body module can guarantee stable operation energy efficiency of a compressor, and reduces abnormal mechanical noise. The invention further provides a pump body and the compressor; and the same beneficial effects are achieved. In addition, as the roller is provided with the annular groove structures, the volumeof crescent space can be increased under the condition of not changing the size compared with a traditional roller, and the exhaust quantity of the compressor is effectively improved.
Description
technical field [0001] The present application relates to the technical field of compressors, in particular to a pump body assembly, a pump body and a compressor. Background technique [0002] Inverter compressors are widely used in modern air conditioners due to their superior energy adjustability. The rolling rotor compressor is one of them. The pump body is one of the important components of the compressor. Composition, the upper flange, the roller, and the lower flange are sleeved on the crankshaft in sequence along the axial direction of the crankshaft, forming a dynamic seal with the cylinder, so that a crescent-shaped space is formed inside the cylinder, and the end of the slide is pressed against the rolling surface by a spring. On the outer surface of the roller, the crescent-shaped space is divided into a suction chamber and a compression chamber, driven by the crankshaft, to complete the process of suction, compression and exhaust. [0003] However, the rollers ...
