Screw air compressor cleaning and maintenance--6, return check valve cleaning
The check valve is composed of a valve body, a steel ball, a steel ball seat and a spring. Oil and gas mixture compressed air compressor mainframe first in oil tank by centrifugal force due to the initial separation, oil weight greater than air, most of the solid oil gas mixture by a centrifugal force to the oil tank, screw air compressor and internal pressure under the action of returned to the host for a lubrication cycle, compression the air contains a small amount of oil through the oil and gas separator separated again, lubricating oil at the oil and gas separator separates the oil and gas will fall to the bottom of the separator, in order not to let this part of the oil with compressed air away, with a unit of oil and gas pipe into the bottom of the separator in the design, through the pressure in this part oil directly into the lubricating and a check valve, the oil pipe, screw air compressor oil return valve single title.
Its function is to recover the oil from the oil and gas separator to the main engine without causing the main oil to flow back to the gas separator. The oil return single valve is connected to the valve body and unscrewed from it. Spring, steel ball and steel ball seat are taken out.
