Problems solved by technology
The wear of the pump body parts is a key factor affecting the reliability of the scroll compressor, because the friction between the pump body parts and the high temperature generated by the compressed refrigerant will reduce the lubricating properties of the refrigeration oil, thereby accelerating the wear of the pump body parts
In addition, for the working condition of suction with liquid, the liquid refrigerant deposited at the bottom of the lower cover is transported by the oil pump to the oil pool of the upper bracket, and the refrigerated oil with liquid refrigerant is scooped out by the main balance weight to the friction contact surface of the movable scroll and the upper bracket , causing wear between the movable scroll and the upper bracket, thus affecting the reliability of the compressor

The invention relates to the technical field of daily electric appliances, in particular to a scroll compressor and refrigeration equipment. The scroll compressor comprises an upper support, a staticscroll plate and a liquid supply pipe, and the upper support is provided with a liquid supply hole and an oil pool which communicate with each other; the static scroll plate is installed on the uppersupport, the static scroll plate is provided with a liquid inlet hole, a cooling groove and a liquid discharge hole, and the liquid inlet hole, the cooling groove and the liquid discharging hole communicate with one another; and the two ends of the liquid supply pipe are connected with the liquid supply hole and the liquid inlet hole correspondingly so as to communicate with the oil pool and the cooling groove. According to the scroll compressor, the static scroll plate is cooled to improve the friction environment thereof, and at the same time, the content of a liquid refrigerant deposited inthe oil pool of the upper support can be reduced.
Description
technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a scroll compressor and refrigeration equipment. Background technique [0002] Scroll compressors are widely used due to their advantages of simple structure, low noise and high working efficiency. The wear of the pump body parts is a key factor affecting the reliability of the scroll compressor, because the friction between the pump body parts and the high temperature generated by the compressed refrigerant will reduce the lubricating properties of the refrigeration oil, thereby accelerating the wear of the pump body parts . In addition, for the working condition of suction with liquid, the liquid refrigerant deposited at the bottom of the lower cover is transported by the oil pump to the oil pool of the upper bracket, and the refrigerated oil with liquid refrigerant is scooped out by the main balance weight to the friction contact surface of the movable...
