The detailed process of air compressor working principle

1, Inhalation process:
The suction port on the screw inlet side must be designed so that the compression chamber can be fully inspiratory and the screw compressor does not have an intake and exhaust manifold. The intake air is only opened by a regulating valve, When the rotor is rotated, the tooth groove space of the main and auxiliary rotor has the largest space when it is transferred to the opening end of the inlet end. At this time, the tooth groove space of the rotor is connected with the free air of the air inlet. When the exhaust is completed, the tooth groove is in a vacuum state, when transferred to the intake port, the outside air is inhaled, along the axial flow into the main and auxiliary rotor teeth. When the air is filled with the entire tooth groove, the rotor's intake side of the face away from the chassis of the air inlet, the air between the tooth groove is closed, the above is [intake process]. 4.2 closed and transportation process: the main and vice two rotors at the end of the suction, the main and vice rotor teeth and the closure of the box closed, then the air is no longer out of the gap in the groove, that is [closed process]. The two rotors continue to rotate, the tooth peak and the tooth groove in the suction side of the anastomosis, the surface gradually moved to the exhaust side, that is [delivery process]. 4.3 compression and fuel injection process: in the transport process, the meshing surface gradually moved to the exhaust end, that is, between the meshing surface and the exhaust groove between the groove gradually reduced, the gas inside the trench gradually compressed, the pressure increases, This is [compression process]. While the compression while the oil is also due to the role of pressure and spray into the compression chamber and air mixed.
 
2, Exhaust process:
When the engaged end of the rotor is brought into contact with the exhaust of the casing, the compressed gas is discharged at the maximum pressure of the compressed gas until the engaging surface of the tooth crest and the tooth groove is moved to the exhaust end face, (The exhaust process), at the same time the length of the groove between the rotor meshing surface and the housing inlet is the longest, and the suction process is in turn In progress.
 
3, compression and fuel injection process:
During the conveyance process, the meshing surface gradually moves toward the exhaust end, that is, the gap between the meshing surface and the exhaust port is gradually reduced, and the gas in the groove is gradually compressed and the pressure is increased, that is, [compression process]. While the compression while the oil is also due to the role of pressure and spray into the compression chamber and mixed with air.
 
4, the exhaust process:
When the meshing end of the rotor is turned into contact with the exhaust of the casing, the compressed gas is discharged at the maximum pressure of the compressed gas until the engaging surface of the tooth crest and the tooth groove is moved to the exhaust end face, The meshing surface and the housing exhaust port of this tooth groove space is zero, that is completed (exhaust process), while the rotor meshing surface and the chassis inlet gap between the length of the longest, the suction process And in progress.
