Technical field
The utility model belongs to Compressor Technology field, more particularly to a kind of variable compressor copper facing swash plate.
Background technique
In our life, walks anywhere all see compressor (compressor), be to mention low-pressure gas
It is upgraded to the driven fluid machinery of one kind of high pressure gas, is the heart of refrigeration system, it sucks the system of low-temp low-pressure from air intake duct
Refrigerant gas is operated after compressing with piston to it by motor, the refrigerant gas of high temperature and pressure is discharged to exhaust pipe,
Power is provided for refrigeration cycle, to realize compression → condensation (heat release) → expansion → evaporation (heat absorption) refrigeration cycle, straight line
Compressor is to be compressed using magnetic suspension principle and helical ring hydrodynamics structure to gas, provides power for refrigeration, press
Contracting machine divides piston compressor, helical-lobe compressor, centrifugal compressor, linear compressor etc., and piston compressor is generally by shell, electronic
Machine, cylinder body, piston, control equipment (starter and thermal protector) and cooling system composition, the type of cooling have oil cold and air-cooled, from
So three kinds cooling, linear compressor does not have axis, without cylinder body, sealing and radiator structure, on the current technology, swash plate durability
Not high, the service life is low.
