How Oil Flows in Electric Screw Air compressor?
56In my previous post,you come to know about Air Flow of Screw Air Compressor.The flow of Oil is much more important in any Screw Air Compressor.The Oil in Screw Air Compressor works as Coolant,Sealant and Lubricant.Therefore it is very important to take due care about Oil.
In Screw Air Compressor the Flow of Air and Oil has made combined effect on performance of the Compressor.It will be better to know the circulation of Oil for clear knowledge of Screw Air compressor.
From below description,you will come to know,How Oil flows and what is the importance of Oil in Screw Air Compressor.
Oil is circulated by the Receiver Air Pressure to various parts of the Compressor where it serves as Lubricant,Coolant and Sealant.Cool Oil is injected directly on to the Rotors limiting the Temperature rise of the Air during Compression and Sealing the Clearance between the Rotor Lobes,Casing and End plates.
In addition Oil is directed to the Bearings and Gears.The Air which is being Compressed mixes with the Oil which is introduced into the Compression Chambers and forms Mist.This Air-Oil mixture then enters the Receiver.
The Oil flows from the Air-Oil Receiver to Oil Cooler through a By-Pass Thermostat which By-Passes Oil Cooler upto 80 Degree Centigrate.The Oil flows through Strainer,Oil Check Valve, and then to Oil Filter.
Should the Filter become so Clogged with Dirt so as to seriously restrict the flow of Oil,a Relief Valve inside the Filter opens to allow the Oil to By-Pass the Filter Element.The Cooled Oil from the Filter is then piped to Oil Inlet Manifold.
At the Manifold three outlet connections are taken to
A)"Y" type Strainer and Choke to Step-Up Gears.
B)Male and Female Rotors.
C)Bearings.
The Air and Oil Mist passes through Air Discharge Valve to Air-Oil Receiver.The Cycle is thus repeated.
