Description
Technical field
This utility model relates to a kind of low noise compressor.
Background technology
Compressor, is a kind of driven fluid machinery that low-pressure gas is promoted to gases at high pressure,
It it is the heart of refrigeration system.It sucks the refrigerant gas of low-temp low-pressure from suction nozzle, by electricity
After machine operating drives piston to be compressed it, discharge the cold-producing medium gas of High Temperature High Pressure to exhaustor
Body, provides power for kind of refrigeration cycle, thus realizes compression → condensation (heat release) → expansion → steaming
Send out the kind of refrigeration cycle of (heat absorption).Linear compressor, is to use magnetic suspension principle and helical ring
Hydrodynamics structure, is compressed gas, provides power for refrigeration.Compressor divides piston pressure
Contracting machine, helical-lobe compressor, centrifugal compressor, linear compressor etc..Piston compressor typically by
Housing, motor, cylinder body, piston, control equipment (trigger and thermal protector) and cooling
System forms.The type of cooling has oil cold and air-cooled, natural cooling three kinds.Linear compressor does not has
Axle, does not has cylinder body, sealing and radiator structure.The compressor of general domestic refrigerator and air-conditioner is
Using single-phase alternating current as power supply, their structural principle is essentially identical, but the system of both uses
Cryogen is different.Compressor produces in a pipeline fashion.At engineering shop's (bag
Include casting) produce cylinder body, piston (rotating shaft), valve block, connecting rod, bent axle, end cap
Deng parts；Rotor, stator is assembled in motor workshop；Housing etc. is produced in press workshop.
Then carry out assembling at assembly shop, weld, cleaning, drying, after pack out through inspection is qualified
Factory.Compression ratio is a kind of technology representation of pressure differential, and its implication is high-pressure side absolute pressure
Absolute pressure divided by low-pressure side.The calculating of compression ratio must use absolute pressure value.In order to keep away
Exempt to make compression ratio value of calculation that negative value occurs, when calculating pressure ratio, must use absolute pressure, and not
It it is meter pressure.Use absolute pressure value just can make compression ratio value of calculation on the occasion of, the most just have a mind to
Justice.
Current existing compressor operating less stable, uses noise relatively big, installs inconvenience,
Structural volume is bigger.
Utility model content
