Screw compressors rely 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.
Screw compressors rely 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, the economic benefit decreases, so the exhaust pressure has a very significant impact on the energy consumption of the compressor.
Screw air compressors are widely used in mining, chemical, power, metallurgy, construction, machinery, refrigeration and other industrial sectors, in a wide range of capacity and mining, and gradually replace other types of compressors. Statistics show that the sales volume of screw compressors has accounted for more than 80% of the sales volume of positive displacement compressors, and 50% of all positive displacement compressors are screw compressors.
The screw-type air intake port on the air intake side must be designed so that the compression chamber can fully inhale, while the screw compressor does not have an air intake and exhaust valve group. The air intake is only adjusted by the opening and closing of a regulating valve. When the rotor rotates, the tooth groove space of the main and auxiliary rotors will be large when it is turned to the opening of the air intake end wall. At this time, the free air between the tooth groove space of the rotor and the air inlet is connected, therefore, all the air in the tooth groove is discharged during exhaust. When the exhaust is over, the tooth groove is still in a vacuum state. When it turns to the air inlet, the outside air is sucked in and flows into the main and auxiliary rotors along the axial direction. In the tooth groove.
