Working principle of moving screw air compressor a. The whole process of inhalation: The screw-type intake side suction port must be designed to allow the compression chamber to fully inhale. The screw compressor has no intake and exhaust valve groups. The intake air is only adjusted by the opening and closing of a regulating valve. When the rotor rotates, the space of the main and auxiliary rotors is turned to When the inlet end wall is open, the space is the largest. At this time, the space of the rotor and the free air between the air inlets are in communication with each other. Therefore, when the exhaust air is exhausted, the air of the groove is completely discharged, and when the exhaust ends, The groove is still in a vacuum state, and when it is turned to the intake port, the outside air is sucked and flows axially into the groove of the main and auxiliary rotors. When the air fills the entire tooth groove, the air intake side end surface of the rotor is turned away from the air inlet of the casing, and the air between the tooth grooves is closed. b. Closing and transmission process: When the main and auxiliary rotors are at the end of the inhalation, the main and auxiliary rotor tooth peaks will be closed with the casing. At this time, the air is closed in the tooth groove, but no more outflow, the two rotors continue to rotate. The tooth peak and the groove are aligned at the suction end, and the anastomosis surface gradually moves toward the exhaust end.
c, compression and fuel injection process: During the conveying process, the meshing surface gradually moves toward the exhaust end, that is, the gap between the meshing surface and the exhaust port gradually decreases, and the gas in the groove is gradually Compression, pressure is increased, this is the [compression process]. At the same time, the lubricating oil is also injected into the compression chamber and mixed with the chamber gas due to the pressure difference. d. Exhaust process: When the meshing end face of the rotor is turned into communication with the exhaust of the casing, (the pressure of the compressed gas is the highest), the compressed gas begins to discharge until the meshing surface of the tooth peak and the groove moves to the exhaust. End face, at this time, the space between the two rotor meshing surfaces and the casing exhaust port is zero, that is, the completion (exhaust process), at the same time, the length of the groove between the rotor meshing surface and the casing air inlet is the highest. Long, the inhalation process is going on.
Mobile screw air compressor Advantages:
1. High reliability: There are few compressor parts and there are no easily damaged parts, so it is more reliable. Long life; 2. Convenient operation and maintenance: High degree of automation, operators do not have to go through long-term professional training, can achieve unattended operation; 3, better power balance performance:
no unbalanced inertial force, smooth High-speed operation, can achieve no basic operation, especially suitable for use as a mobile compressor; 4, strong adaptability: with the characteristics of forced gas transmission, the volume flow is almost independent of the exhaust pressure, can be in a wide range of speed Maintain high efficiency.
