1. Working principle and design of screw compressor
In the screw compressor, the other rotor (male rotor or male rotor) is driven by the oil film formed by the oil spray on the main rotor. This design principle is based on complex mechanical engineering and fluid dynamics. The screw compressor achieves gas compression by rotating in opposite directions in the cylinder with two tightly matched rotors, the male rotor and the female rotor.
2. Multiple roles of oil film in screw compressor
The oil film formed by oil spray plays a vital role in the screw compressor. It plays a lubricating role, reduces the friction between the rotor and the casing, prolongs the service life of the equipment, and also undertakes the functions of sealing and cooling. The oil film fills the tiny gaps between the rotors, forming a seal to prevent gas leakage and ensure compression efficiency. The oil film absorbs the heat generated during the compression process, takes away the heat through the oil circulation system, and maintains the normal operating temperature of the equipment.
3. Oil film drive mechanism and rotor rotation
During the driving process, the main rotor (male rotor or male rotor) is driven to rotate by the motor, while the other rotor (male rotor or male rotor) is driven to rotate by the transmission of the oil film. The oil film forms a thin layer of oil on the surface of the rotor. When the main rotor rotates, the oil film generates shear force on the surface of the rotor, which drives the other rotor to rotate. Due to the existence of the oil film, there is no direct metal contact between the two rotors during rotation, which reduces wear and noise and improves the operating efficiency and reliability of the screw compressor.
4. The relationship between the structural design of the screw compressor and the oil film
The formation and function of the oil film are closely related to the structural design of the screw compressor. The shape, size and clearance of the rotor are precisely calculated and optimized to ensure that the oil film can be evenly distributed and transmit power. During the design process, engineers need to comprehensively consider factors such as oil viscosity, temperature and pressure to ensure that the oil film can exist stably under various working conditions and meet the performance requirements of the screw compressor.
