Q:How to deal with the liquid hammer phenomenon of compressor
Liquid hammer occurs mainly in piston compressors. As refrigerant liquid (or lubricating oil) is sucked in by compressor, it causes abnormal shock accident of compressor
Q:What is the purpose of a two-stage compression refrigeration cycle?
The traditional air conditioning system can only achieve the lowest heat at minus 7 degrees Celsius environment itself, and adopting the two-stage inverter air conditioner double stage compressor can be achieved in the limit condition minus 30 DEG C under strong heating
Q:What are the technical parameters of the compressor?
The volume efficiency of a compressor is the ratio of the actual gas flow to the theoretical gas flow
Q:How many types of drive are there in an air conditioner compressor?
At present, scroll compressors have absolute advantages in the field of cabinet air conditioners. In the field of automotive air conditioning, the refrigeration coefficient of scroll compressor has reached 2, showing a strong competitive edge. The development of scroll compressor is to expand its refrigeration range, further improve efficiency, use alternative refrigerants and reduce manufacturing costs and so on.
Q:What are the air compressors for?
Air jet loom with compressed air blowing weft to replace the shuttle
Q:What is the working principle of the compressor?
A driven fluid machine that promotes low-pressure gas as a high-pressure gas; the heart of a refrigeration system. It is of low temperature and low pressure refrigerant gas suction pipe from the suction, through the operation of the motor drives the piston to compress it after high temperature and high pressure refrigerant gas discharge pipe to the exhaust, to provide power for the refrigeration cycle, so as to realize the compression and condensation (exothermic), expansion and evaporation (endothermic) refrigeration cycle
Q:What is the function of the hydraulic differential controller in the compressor?
When the compressor works, an oil pump forces the oil circulation lubrication and cooling, and the oil pressure difference controller is a safety switch for the screw compressor
Q:What about compressor overload protection?
The starting capacitor of the compressor is invalid and short circuited, the starting winding is broken, the running winding partial turn short circuit, the compressor holding shaft and the clamping cylinder can cause the compressor starting current to be too large, and the protective relay action
Q:What is the cause of the overload of the air conditioning compressor?
Dust on the outside condenser can be cleaned, and the heat insulation cotton wrapped on the compressor can be removed
Q:What is the mean of condenser?
The condenser is a part of the refrigerating system, and belongs to a heat exchanger
