375 Cfm Diesel Air Compressor
The working principle of diesel air compressor
1. The suction process: the screw compressor has no intake and exhaust valve, and the intake is only adjusted by the opening and closing of a regulator. When the space between the main and auxiliary rotors is transferred to the opening of the inlet end wall of the machine, the space is large. At this time, the space of the tooth grooves below the rotor is communicated with the free air of the intake port. In the exhaust, the air in the gully is discharged through the whole number. When the exhaust is finished, the groove is in a vacuum state. When the air inlet is turned to the air inlet, the outside air is inhaled and flows into the teeth of the main and the secondary rotors along the axial direction. When the air is full of tooth grooves, the inlet side face of the rotor is turned off the air inlet of the casing, and the air between the teeth trenches is closed. The above is the intake process.
2. The process of closing and conveying: at the end of the suction, the main and vice-rotor teeth summit and the casing seal are sealed, and the air in the tooth groove is no longer outflow, which is the "closed process". The two rotor continues to rotate, the tooth peak and the tooth groove are in the suction end, and the anastomosis surface gradually moves to the exhaust end, which is the "transportation process".
3. The compression and injection process: during the transportation of diesel air compressor, the meshing surface gradually moves to the exhaust end. That is, the tooth groove space between the meshing surface and the vent gradually decreases, and the air in the tooth groove is gradually compressed and the pressure increases gradually. This is the "compression process". At the same time, the lubricating oil is also injected into the compression chamber and mixed with the air because of the pressure difference.
4. Exhaust process: when the end surface of the exhaust port of the rotor is connected with the case, when the pressure of the compressed gas is high, the compressed gas starts to discharge until the meshing surface of the tooth peak and the gear groove moves to the exhaust end face of the casing. At this time the space between the meshing surface of the two rotor and the exhaust port of the engine shell is zero, that is, the "exhaust process" is completed. At the same time, the length of the tooth groove between the meshing surface of the rotor and the air inlet of the casing is long, so a new compression cycle is started.
