Efficiency of an air filter by changing the static outlet pressure of a air filter of a compressor

Abstract

Twin-screw compressors are widely used in aerodynamics, refrigeration and other fields. The screw rotors are the core component of the screw compressor and affect the performance of the compressor. Compressed air filtration plays a hugely important role in any compressor installation. Having a high-quality air compressor filter will protect your system from particulates, dirt, dust, solid particles, and oil. Harmful contaminants like these can cause damage to your equipment and downstream machinery, wearing down parts and causing blockages. A thermal process simulation model considering leakage is established to calculate the efficiency of the compressor. Different lead change methods are compared by evaluating the contact line, exhaust port and simulation results. The results show that the compressor obtains better performance when the lead decreases rapidly on the discharge side. Furthermore, the effects of the wrap angle and internal volume ratio on variable-lead rotors are studied. The work provides a reference for the design of the screw compressor rotor
