Description
Technical Field
The utility model relates to a scroll compressor field especially relates to a novel horizontal scroll compressor.
Background
The vehicle-mounted compressor comprises an air-conditioning compressor for a small car, an air-conditioning compressor for a bus and a freezing and refrigerating compressor, and the horizontal compressor is mainly used. In the past, the mainstream compressor form is that an engine drives a belt pulley to drive the compressor to run, and in recent years, the full-scale compressor is more popular. The full electric compressor integrates the motor and the compression part together, eliminates a shaft seal, has small leakage and high efficiency, and is easy to realize the control of the rotating speed. The scroll compressor in the full electric air conditioner compressor is more and more popular mainly because of the low cost, high efficiency and wide use working condition compared with the swash plate compressor, especially in the application of heat pump, but the scroll compressor has higher requirement on lubrication because of more friction surfaces.
The design concept of the horizontal vehicle-mounted compressor, in particular to an air conditioner compressor of a small car is that when the volume of an air suction cavity is small enough, because the gas flow velocity is high enough, lubricating oil mixed in refrigerant can reach the part needing lubrication along with the refrigerant, and the normal work of the friction part is ensured. This design has two disadvantages:
(1) the refrigerant does not necessarily reach the parts needing lubrication;
(2) the flow rate of the refrigerant is greatly influenced by application conditions, particularly the flow rate of the refrigerant is very low under the condition that the outdoor temperature is very low in the heat pump application which is popular on new energy automobiles recently, and meanwhile, the flow rate of the refrigerant is further reduced when the variable frequency motor runs at a low speed.
In order to solve the problem, the scheme which is easy to realize is to fill excessive lubricating oil, so that the quantity of oil circulating in the refrigeration heat pump system is kept large enough, the problem of insufficient oil circulation quantity under extreme working conditions is solved, meanwhile, the oil storage quantity in the compressor is also ensured to be sufficient, and the moving parts of the compressor can be ensured to obtain oil. This design has two disadvantages:
(1) the excessive oil circulation quantity reduces the efficiency of the heat exchanger and the heat exchange quantity;
(2) the excess oil stirs the moving parts of the compressor and the oil, consuming additional idle work.
From the perspective of ensuring reliability and heat exchange efficiency simultaneously, except for external oil circulation, it is necessary when oil circulation is designed inside the compressor. It is popular to design an oil pump in the motor cavity, and the oil pumped by the oil pump is delivered to the compression cavity and the friction part through the central hole of the shaft, but the design is proved to be effective in application, and has the disadvantages of complicated structure, high cost and additional useless power consumption and noise.
