The working principle of a screw-type air compressor: The air cylinder of the screw-type air compressor is equipped with a pair of meshed spiral male and female rotors, which rotate in opposite directions. The gap between the rotors, the casing, and the space between them is only 5-10 wires. The main rotor is driven by an engine or an electric motor. The intermeshing pores are driven by the injection of the main rotor or by the end and concave parts of the main rotor and the oil film. The synchronous gears on the rotor side drive. The screw rotor slots are filled with gas when passing through the inlet. When the rotor rotates, the rotor slots are closed by the casing wall to form a compression chamber. When the rotor slots are closed, the lubricating oil is sprayed into the compression chamber and sealed, cooled, and lubricated. When the rotor rotates and compresses the mixture of lubricating oil, oil, and gas, the volume of the compression chamber decreases, and the oil-gas mixture is compressed to the exhaust port. When the compression chamber passes through the exhaust port, the oil and gas mixture is discharged from the compressor to complete the suction compression - exhaust process. Each rotor of the screw machine is supported by anti-friction bearings kept by the end cover close to the shaft end. The inlet end is supported by roller bearings, and the exhaust end is usually supported by bearings. The bearing is an exhaust end, that is, a thrust bearing, which is supported by a pair of conical rollers to resist axial thrust and withstand radial loads. The minimum clearance required for axial operation is provided. The working cycle can be divided into three processes: suction, compression, and exhaust. When the rotor rotates, each pair of meshed teeth continuously complete the same working cycle.
Advantages of screw air compressors:
The screw compressor is similar to the piston compressor and belongs to the type of volumetric compressor. The screw air compressor has the following advantages in terms of efficiency.
2. High reliability. The screw compressor has fewer components and less wear on those components, resulting in stable operation and a longer service life. The major maintenance interval can reach 40,000 to 80,000 hours.
3. Easy to operate and maintain. The screw compressor is highly automated, allowing operators to achieve unmanned operation without the need for long-term professional training.
4. Excellent power balance. The screw compressor has no unbalanced inertia, and the machine operates smoothly at high speeds, enabling non-standard operations. It is particularly suitable for mobile compressors. It has a small size, light weight, and occupies a small area.
5. Adaptability. The screw compressor has the characteristic of forced ventilation. The volumetric flow rate is almost independent of the exhaust pressure, and it can maintain high efficiency over a wide range. Moreover, it can be applied to various working conditions without changing the compressor structure. You.
Both vortex-type and screw-type air compressors belong to volumetric rotary compressors. The difference lies in that the vortex-type air compressor uses rotors and stators to form multiple compression chambers. The internal volume changes to achieve gas intake and compression. The compressed air in the screw-type air compressor is achieved through the volume changes in the tooth gaps between the parallelly arranged male and female rotors inside the housing. Screw air compressors are widely used in various industrial fields such as machinery, metallurgy, power, medicine, packaging, chemical engineering, food, mining, textile, transportation, etc. Mainstream air compressor manufacturers produce these machines.
