Screw rotor of air compressor

Product Description
The screw rotor of an air compressor, as the core component of a screw type air compressor, consists of a pair of precision manufactured male and female screws (also known as primary and secondary screws or concave convex screws). These screws are arranged in parallel inside the air compressor and tightly mesh together. Among them, the male screw (convex screw) is usually driven by an electric motor as the driving shaft to rotate, while the female screw (concave screw) rotates as the driven shaft.
During the operation of a screw air compressor, air is drawn in from the inlet and enters the compression chamber enclosed by the male and female screws and the casing. As the screw rotates, the volume of the compression chamber gradually decreases, thereby compressing the air. During this process, the small gaps between the screw rotors and between the screw and the casing ensure the high efficiency and stability of compression. At the same time, lubricating oil is sprayed into the compression chamber to provide lubrication, cooling, and sealing.
The design of screw rotors typically uses high-strength, wear-resistant materials such as alloy steel or stainless steel to withstand the pressure and wear generated during high-speed rotation and compression processes. In addition, the surface of the rotor is specially treated, such as chrome plating or sprayed with wear-resistant coatings, to further improve its durability and performance.
The precise engagement and rotation of the yin-yang screw not only achieve continuous compression of air, but also ensure the stable operation and low noise characteristics of the air compressor. Screw air compressors have been widely used in industries, manufacturing, and other fields due to their high efficiency, energy efficiency, stability, and reliability.
1、 Basic composition and working principle
Basic composition:
The screw rotor of an air compressor is usually composed of a pair of parallel, interlocking male and female rotors. Among them, the male rotor (also known as the active rotor or convex rotor) is driven by an electric motor to rotate at high speed, while the female rotor (also known as the driven rotor or concave rotor) rotates along with the male rotor.
working principle:
During the inhalation process, external air is drawn into the tooth slot space formed by the two screw rotors through the intake port.
As the rotor continues to rotate, the tooth slot space gradually decreases, the air is continuously compressed, and the pressure gradually increases.
When the set exhaust pressure is reached, compressed air is discharged from the exhaust port, completing the entire compression cycle.
2、 Characteristics and advantages
Efficient compression:
The screw rotor is manufactured using high-precision machining technology, ensuring small clearances between rotors and between rotors and stators, thereby achieving efficient compression processes.
The special treatment of the rotor surface, such as chrome plating or spraying wear-resistant coatings, further reduces wear and friction, and improves compression efficiency.
Stable operation:
Screw rotors are usually made of high-strength alloy steel or stainless steel materials, which can withstand the pressure and wear caused by high-speed rotation.
Bearings play a role in supporting and guiding the rotation of the screw rotor in screw air compressors, ensuring the stability of the rotor during high-speed rotation.
Sealing performance:
Screw air compressors use advanced sealing technologies such as labyrinth seals, mechanical seals, or dry gas seals to effectively prevent gas leakage during the compression process.
High quality sealing materials have good elasticity and wear resistance, which can maintain stable sealing effect during long-term use.
Strong adaptability:
Screw air compressors have the characteristic of forced gas delivery, and the exhaust volume is basically not affected by the exhaust pressure.
The gap between rotors can withstand the impact of liquids, so screw air compressors can pressurize and send out gases containing liquids, dust, polymeric gases, etc.
Easy to maintain:
Screw air compressors have fewer components and fewer vulnerable parts, making them reliable to operate and easy to maintain.
Regularly inspecting the wear, surface smoothness, and meshing clearance of the screw rotor can promptly detect and repair potential problems.
3、 Application and Prospect
Screw air compressors have been widely used in the industrial field due to their high efficiency, stability, and reliability. With the continuous development of the manufacturing industry and the increasing demand for energy efficiency, the market demand for screw air compressors will continue to grow. Meanwhile, with the continuous advancement and innovation of technology, the design of screw rotors will be further optimized, and their performance will be further improved to meet a wider range of application needs.
