What is the application of screw compressor?
Screw compressors are commonly used in a variety of process gas, process refrigeration and natural gas applications, including individual wellhead boosters, low pressure gathering systems, low stage boosters to existing reciprocating machines, fuel gas compression, solution gas and vapor recovery compression systems.
What is true for screw compressors?
Working Principle of a Screw Compressor. The oil injected rotary screw compressor is a positive displacement type compressor. A given quantity of air or gas is trapped in a compression chamber and the space that it occupies is mechanically reduced, causing a corresponding rise in pressure prior to discharge.
On which principle air pump is based?
The working principle of the air pump is that the engine drives the crankshaft of the air pump through two triangular belts, which drives the piston to inflate, and the inflated gas is introduced into the gas storage cylinder through the air duct.
Why oil is used in screw compressor?
In an oil injected rotary screw compressor, oil is used for four main purposes. It is injected into the compression chamber to cool the machine, provide adequate lubrication of the moving parts, provide sealing and to aid with noise dissipation.
How many screws a screw type compressor have?
Screw compressors use two meshing helical screws, while piston air compressors use pistons driven by a crankshaft. Another difference is the moving parts as the screw compressor has two moving parts which are not in contact while the piston compressor has a lot of moving parts.
What are the advantages of a screw compressor?
What are the advantages of using a Rotary Screw Compressor?
- Safe and Convenient.
- Functions at extreme weather conditions.
- They are designed to run tools that generate more power that typical equipment.
- They are easier to maintain.
- They run quietly despite their massive air flow.
- They are good energy conservers.
What is a 2 stage compressor?
A two-stage air compressor compresses the pressurized air a second time so the pressurized air being used will have double the pressure for double the efficiency and power.
What are the four stages of compression?
Compression occurs within the cylinder as a four-part cycle that occurs with each advance and retreat of the piston (two strokes per cycle). The four parts of the cycle are compression, discharge, expansion and intake.

How does a 2 way air pump work?
They have a piston inside and two one-way valves: one going to the bike tire and one to the outside air. When the pump is pulled up, the pressure inside decreases. This pulls in air from the outside but closes the valve to the bike tire. When the piston is pushed down again, it compresses the air inside.
What is the working principle of air compressor?
As the piston moves downward,atmospheric air fills the cylinder,resulting in a full cylinder filled with air at ambient pressure.
