What are the unique properties of screw air compressors？

The main performance parameters of screw air compressors are power, volumetric flow, suction pressure, outlet temperature, discharge pressure and speed. In the design of screw air compressors, a pair of intermeshing rotors is a very important parameter. Because it is closely related to the performance of the compressor.

The male and female rotors of the screw compressor can be regarded as a pair of helical gears that mesh with each other. Therefore, the profile of the female and male rotors of the screw compressor must also satisfy the meshing law. The intersection line between the tooth surface of the rotor and the vertical plane of the rotor axis is called the rotor profile. The rotor profile of the screw compressor is divided into symmetric profile and asymmetric profile, as well as unilateral profile and double profile. When the profile on both sides of the tooth top center line is exactly the same, it is called symmetric profile.

Conversely, when the profile lines on both sides of the tooth top center line are different, it is called an asymmetric profile. There is a profile line only on the inner or outer side of the rotor pitch circle, which is called a unilateral profile line. There are contour lines inside and outside the pitch circle, which are called bilateral contour lines. Generally speaking, the development and design of the new line directly affects the performance of the screw air compressor, and the performance of the screw air compressor also depends on the design of the profile.

The screw compressor relies on the continuous meshing of the rotor to output compressed gas. Therefore, the change of the spindle speed will affect the volume flow and exhaust pressure of the compressor. Therefore, the spindle speed is a major factor affecting the performance of the screw compressor. When the exhaust pressure increases, the power consumption of the compressor also increases, and the specific power increases, and the economic benefit decreases. Therefore, the exhaust pressure has a very significant impact on the energy consumption of the compressor.

At the same time, some test results show that the external ambient temperature will also affect the performance of the screw compressor. The air temperature in China varies greatly in different seasons and in different regions, and the suction temperature of the compressor is different when the ambient temperature is different. This parameter will directly affect the performance of the screw compressor. Therefore, the analysis of the above factors affecting the performance of the screw compressor will greatly help the use of the screw compressor.
