Problems solved by technology

After actual use, it was found that when the suction pressure of the compressor is extremely low in some extreme working conditions, the oil entering the compression cavity of the compressor with the refrigerant is greatly reduced, and the moving parts in the compressor are lacking in oil lubrication and cooling. The temperature of the moving parts rises sharply, which can easily cause wear on the contact surface between the diaphragm and the rollers, and damage the compressor

Abstract

The present application provides a pump body assembly, a compressor and an air conditioner, comprising a crankshaft, a compression part and a partition part, the compression part and the partition part are sleeved on the crankshaft, and there are at least two compression parts, The partition part is arranged between the adjacent compression parts, a central oil passage is arranged in the crankshaft, a section of the crankshaft and the partition part sleeved is a connecting section, and a connecting section is arranged on the connecting section. A first oil hole, the first oil hole communicates with the central oil passage. The pump body assembly provided in the embodiments of the present application can reduce the wear between the partition part and the compression part when the suction pressure of the compressor is very low.

Description

technical field [0001] The application belongs to the technical field of air conditioning, and in particular relates to a pump body assembly, a compressor and an air conditioner. Background technique [0002] Rolling rotor compressors have the outstanding advantages of small size, low cost and high energy efficiency, and are now widely used in various fields such as air conditioners and heat pumps. After actual use, it is found that when the suction pressure of the compressor is extremely low under certain extreme operating conditions, the oil entering the compression chamber of the compressor with the refrigerant is greatly reduced, and the moving parts in the compressor are due to the lack of oil lubrication and cooling. The temperature of the moving parts rises sharply, which can easily cause the contact surface between the separator and the roller to wear and damage the compressor. SUMMARY OF THE INVENTION [0003] Therefore, the technical problem to be solved by the ...
