When the oil-air mixture screw, the screw compressor unit is collected in the oil separator tank. Accumulates in the bottom of oil tank, while a small amount of oil mixed pulverized through the air separator.
The air inlet hole of the oil separator title passes from the falling oil and air separator separator entering from outside the inner layer of paper out of. Very small amount of oil in the last separtörün separator paper is collected at the bottom and called skavenç thin line oil return line pipe leakage is absorbed back into the screw.
Separator last air, minimum pressure valve to the income and then passes out. Minimum pressure valve outlet passes (up to 5 million ie 5 ppm by weight pulverized fat) of fresh air after being cooled at cooling the air compressor, compressor unit shall be given to the output. Of moisture in the air can leave the air is cooled yoğuşturularak.
Minimum pressure valve opens at a pressure between 3-4 bar (generally is set to 3.5 bar). Compressor oil separator or separator in the header tank when you have less pressure, minimum pressure valve valve remains closed. Thus, the system checks the oil separator tank pressure and oil flow is preserved, as well as extremely fast in low pressure air to move out of the oil is prevented. Minimum pressure valve also irreversible (check) valves and, in the compressed air output of compressor oil separator prevents return to the tank. Feature irreversible valve, minimum pressure valve, to stop when the compressor is running or idle, oil separator tank (also the pressure of the compressor systems) were separated from the external pressure is.
A new entry and exit separator pressure difference between the maximum 0.2 bar'dır. Timing caused pollution and clogged separator to 1 bar pressure loss may occur. Separator pressure difference ranged from 0.5-1 bar (0.8 bar, while the most common) must change the separator.
