Screw Air Compressor:

A rotary screw air compressor is a type of gas compressor that uses a rotary type positive displacement mechanism. Typically the screw air compressor is used to replace the piston compressor, where large quantities of high pressure air are required to operate for large industrial applications or to operate high powered air appliances such as jackhammer. The gas compression process of a rotary screw is a continuous wide speed, so the flow with the piston compressor is very low pulse or flow.

Screw Air Compressor Working:

The screw element was developed for the first time in the 1930s. In this, Mail and Female are two rotors, Mail rotor helps in running female rotor if it is an oil-injection screw compressor; And if this oil free compressor then a timing gear rotates both rotors. Both rotors move harmoniously with the minimum calculation clearance between the two elements. The basic principle of a screw compressor is that the male and female rotors are roaming in the opposite direction, so they pull the air in the middle.As the air progresses with rotors, the air is compressed because the volume space decreases between rotors, so the compressed air with the displacement in the outlet creates. The speed of rotors is optimized at a certain level to reduce the mechanical level (due to heat at very fast speed) and volumetric damage (air damage due to very low speed).

Unlike a piston compressor, a screw compressor usually does not have valves and there is no mechanical force in it which causes an imbalance, this means that it can work at high speeds with large flow rate and now Can also be contained within a small exterior.
