WORKING PRINCIPLE:

    The working of the lubricating system is as follows. The air from atmosphere is drawn into the air compressor and is compressed. The air compressor is driven by the motor. The high pressure air is stored in the air tank. Our system incorporates a solenoid valve and an electronic control unit, heat sensor. Heat sensor may be made to operate at periodic interval of time. Whenever the sensor signal is on, the solenoid valve gets opened. The air from the air tank is now admitted to the rear end of the double acting cylinder. Now the compressed air pushed the piston of the pneumatic cylinder forward. This makes the plunger in the distributor to push the oil towards the outlet of the distributor. So the oil is supplied to various parts where the hoses are connected. The valve is 5/2 solenoid valve which makes the piston of the pneumatic cylinder to its position (left end) after one stroke. During the return stroke a partial vacuum is created at the front end of the oil cylinder. To compensate the vacuum, the oil from the container enters the chamber.   During the forward stroke of piston the oil contained in the chamber is pushed out with pressure. The pressurized lubricating oil is then taken to required points through distributors. Flow control valves are provided in each hose so as to vary the flow of oil to different parts.
