Working principle of screw compressor and introduction of main functional parts
Release time:
2024-05-27
The screw gas compressor is an oil-injected single-stage screw compressor. It uses a coupling direct drive to drive the main engine to rotate and compress the gas, and cool the compressed gas in the main engine by oil injection. The gas + oil mixed gas discharged from the main engine is separated by coarse and fine separation to separate the oil in the compressed gas, and finally obtain clean compressed gas; the cooler is used to cool the oil. Working principle The screw compressor is a type of positive displacement compressor. The gas compression is achieved by the volume change of the teeth of the yin and yang rotors that are parallel and meshed with each other in the casing. The rotor pair rotates in the casing that is precisely matched with it, so that the gas between the rotor teeth continuously produces periodic volume changes and is pushed from the suction side to the discharge side along the rotor axis, completing the three working processes of suction, compression, and exhaust.
Gas flow:
Gas ~ Gas filter ~ Intake valve ~ Host ~ Oil-gas separator ~ Minimum pressure valve ~ Outlet (gas supply)
Lubricating oil flow: Lubricating oil ~ Separation oil tank ~ Temperature control valve ~ Oil cooler or bypass ~ Oil filter Oil stop valve ~ Host
The gas + oil mixed gas changes direction and turns in the separation oil tank, and most of the oil is separated. The remaining small part of the oil is separated through the oil separator 5. This part of the oil is inserted into the pipe in the oil separator and then drawn out from the host air inlet back to the host.
The hot oil in the separation oil tank flows into the temperature control valve. The temperature control valve controls the proportion of the oil flowing to the cooler and the bypass oil according to the temperature of the inflowing oil, so as to control the exhaust temperature not to be too low (ambient temperature + 50 ℃). Too low exhaust temperature will cause the moisture in the gas to precipitate in the separation oil tank, making the oil emulsified and unable to continue to be used. Finally, the oil passes through the filter and is sprayed into the host.
The circulation of lubricating oil is maintained by the pressure difference between the separation oil tank and the low-pressure chamber of the main engine. In order to keep the oil circulation during the operation of the machine, it is necessary to ensure that there is always a pressure of not less than 0.07MP in the separation oil tank. The minimum pressure valve 6 plays this role.
