Operation of a Rotary Screw Compressor
Screw compressors offer a great number of advantages which other kinds of compressors, including the piston-type compressors, do not.
Operation of a rotary screw compressor
The rotary screw compressor has 2 rotors that can push air through it. Pressure is hence created. You can browse https://www.americanhermetics.net/content/compressors/bitzer_screw for screw compressors.
The compression of air is reached and created from the secondary and main rotors that populate and mesh with each other in a casing of double bore and single part design.
Helical grooves are in the main or the primary rotor. The inlet port to the incoming air is located on home's top, which is situated adjacent to the end of the drive shaft. The port for the discharge is located at the bottom, on the housing's opposite end.
From the water-injected or the oil-free designs, the fluid becomes introduced in the next step of compressor performance.
This eliminates the compression heat and also seals all the internal clearances. The injection of this fluid also prevents any type of metal or rotor contact.
They prevent the two rotors from calling each other. Water could be injected into the"compression" chamber so that sealing and cooling can be provided at higher temperatures.
The performance of the screw compressor is in numerous stages so that the efficiency of the process can be made better and maximum pressure can be produced.
In a number of the screw compressor designs, the atmosphere and the oil are discharged directly to the upcoming operational stage.
In the others, the oil has been eliminated, and the atmosphere is cooled between 2 consecutive phases within the intercooler.
