عربى(1) Suction process: screw-type intake side suction port, must be designed to make the compression chamber can be fully suctioned, and double alloy screw compressor and no intake and exhaust valves, intake only relies on a regulator valve open, close the regulator, when the rotor is rotating, the main rotor teeth groove space in the turn to the intake wall opening, the space is the largest, at this time, the rotor's teeth groove space and the inlet of the free air through, because the air is fully discharged in the discharge At this time, the tooth groove space of the rotor is connected with the free air of the air inlet, because the air in the exhaust of the tooth groove is completely discharged, and at the end of the exhaust, the tooth groove is in a vacuum state when it is turned to the air inlet, the outside air is sucked into the tooth groove along the axial direction of the primary and secondary rotors. When the air fills up the whole tooth groove, the air inlet side of the rotor turns away from the air inlet of the casing, and the air between the tooth grooves is closed.
(2) Closed and transport process: the main and vice two rotors at the end of the suction, the main rotor tooth summit and casing closed, this time the air in the tooth groove closed no longer outflow, that is, [closed process]. The two rotors continue to rotate, its tooth peak and tooth groove in the suction end of the anastomosis, the anastomosis surface gradually to the exhaust end of the move.
(3) Compression and oil injection process: in the process of conveying, the jet surface gradually to the exhaust end of the move, that is, the meshing surface and the exhaust port between the teeth between the grooves gradually reduced, the teeth groove of the gas gradually be compressed, the pressure increases, that is, [compression process]. At the same time, the lubricating oil is also sprayed into the compression chamber and mixed with the room gas due to the pressure difference.
(4) Exhaust process: when the rotor mesh faces the chassis exhaust through, (at this time the pressure of compressed gas) the compressed gas begins to discharge until the tooth peak and tooth groove of the mesh surface moved to the exhaust surface, at this time, the two rotor mesh face and chassis exhaust this tooth groove space is zero, that is, the completion of the (exhaust process), at the same time, rotor mesh face and the length of the tooth groove between the chassis inlet and the longest length of their The suction process is going on again.
