The working principle of the air compressor

Breathe in process:


Screw type air inlet side of the suction mouth, must be designed to make the compression chamber can inhale fully, no air intake and exhaust valve group and screw compressor, air intake by a regulating valve opening and closing adjustment, as the rotor turns, main rotor tooth groove space when transferred to the inlet end wall openings, its space is the largest, the rotor tooth groove space and the freedom of the inlet air are interlinked, was all for tooth groove in exhaust air discharge, vent finished, tooth groove is in a vacuum state, when transferred to air inlet, outside air is inhaled, along the axial flow into the main rotor tooth groove. When the air is full of the whole tooth groove, the inlet side of the rotor end face turn away from the chassis, the intake air is blocked between the tooth groove, above, for the admission process. 4.2 closed and transportation process: main two rotor, at the end of the suction and its main rotor tooth summit with casing sealed closed, the air inside the tooth groove closed no longer outflows, namely process [closed]. Two rotor continues to turn, the teeth with tooth groove on the suction side, consistent surface gradually moving to the exhaust end, this is known as [process]. 4.3 compression and oil spraying process: in the process of conveying, mating surface gradually moving to the exhaust end, i.e. between meshing tooth groove between the face and vent gradually decreases, and the gas gradually compressed within the tooth groove, pressure increase, this is known as compression process. And compression lubricating oil at the same time because of the action of pressure difference and spray into the compression indoor mixed with air.


Exhaust process:


When the meshing surfaces of the rotor to the mines with casing exhaust, (highest compressed gas pressure at this time) began to discharge the compressed gases, until the teeth with tooth groove of the mating surface to the exhaust end face, the two rotor tooth meshing surface and chassis vent groove space is zero, namely complete (exhaust process), at the same time the rotor mesh surface and casing length of tooth groove between the inlet and the longest, the suction process is in progress.
