Screw air compressor structure
Air compressor equipment-screw air compressor adopts high-capacity compression components, its rotor outer speed is low and the best oil injection is achieved, achieving high efficiency and high reliability. As of 2012, the manufacturer's design can ensure that the system temperature and compressed air temperature are extremely low. Ensure that all components achieve the best cooling effect and maximum service life.
Drive concept Air compressor equipment-screw-type air compressor drives the compression assembly at the best speed suitable for the application through a high-efficiency transmission system. No maintenance is required during normal operation. It has the advantages of maintenance-free, highly reliable and efficient filtration. Low maintenance costs The unique compressor design of the air compressor equipment-screw air compressor saves unnecessary maintenance costs. All parts are designed for long life. Large inlet filters, oil filters and fine separators ensure the best compressed air quality. All oil filters and separator components within 22kW (30hp) are centrifugal opening and closing, further reducing maintenance time. Built-in intelligent control To reduce operating costs, precise operation control is essential. All screw compressors are equipped with an intelligent control system, and the control menu is simple and easy to use.
work process: The screw compressor is a volumetric gas compression machine with a working volume for rotary motion. The compression of gas depends on the change of volume to achieve, and the change of volume is achieved by the rotary motion of a pair of rotors of the compressor in the casing. The basic structure of the screw air compressor: In the compressor body, a pair of interlocking spiral rotors are arranged in parallel, and the rotor with convex teeth outside the pitch circle is usually called the male rotor or male screw. The rotor with concave teeth in the pitch circle is called a female rotor or a female screw. Generally, the male rotor is connected to the prime mover. The male rotor drives the female rotor to rotate. The last pair of bearings on the rotor achieve axial positioning and bear the compressor The axial force in the. At both ends of the compressor body, openings of a certain shape and size are opened respectively. One for intake, called the air intake; one for exhaust, called the exhaust.
Intake Detailed analysis of the working process of the screw air compressor: the intake process: when the rotor rotates, the space of the tooth groove of the male and female rotors is the largest when it is turned to the opening of the intake end wall. At this time, the space of the rotor groove and the inlet Connected. Because the gas in the tooth groove is completely discharged during the exhaust, the groove is in a vacuum state when the exhaust is completed. When it is turned to the air inlet, the external gas is sucked in and enters the tooth groove of the Yin and Yang rotor in the axial direction. When the gas fills the entire tooth groove, the end face of the rotor intake side turns away from the air inlet of the casing, and the gas in the tooth groove is closed. compression The detailed analysis of the working process of the screw air compressor: the compression process: at the end of the suction of the male and female rotors, the tip of the male and female rotors will be closed with the casing, and the gas will no longer flow out of the tooth groove. The engaging surface gradually moves toward the scheduling end. The space of the tooth groove between the meshing surface and the exhaust port is gradually reduced, and the pressure of the gas in the tooth groove is increased by the compression. exhaust The exhaust process of detailed analysis of the working process of the screw air compressor: when the meshing end surface of the rotor turns to communicate with the exhaust port of the casing, the compressed gas begins to be exhausted until the meshing surface of the tooth tip and the tooth groove moves to the scheduling The end face, at this time, the space between the meshing surface of the male and female rotors and the groove of the casing exhaust is 0, that is, the exhaust process is completed, and at the same time, the length of the groove between the meshing surface and the inlet of the casing reaches The longest, the intake process is carried out again.
