Screw air compressor injection treatment method:
First of all, check whether the oil solenoid valve is faulty. If the oil solenoid valve is normal, further check whether the main exhaust pipe check valve can be closed in time or closed normally. If there is a fault, it should be eliminated.
At present, the twin-screw air compressor is generally no longer installed with oil cut-off solenoid valve, so the main reason for oil injection is the check valve.
The check valve is recommended to use stainless steel valve, because the compressed air contains moisture, the oxidation corrosion of ordinary cast iron valve is fast, easy to cause the check valve corrosion card astringent and loose closure.
Once the power, the solenoid valve, the intake butterfly valve closed, initial isolation.
But the intake butterfly valve generally has a vent or gap, can not be completely isolated from the outside, heavy hammer check valve emergency closure, which is the most effective and the last measure to prevent oil injection.
Because the current twin screw air compressor generally does not install oil break valve, after shutdown through the check valve partition, pressure to the host oil in the machine internal pressure relief to zero, gravity flow back to the oil and gas barrel, heavy hammer check valve is the most effective way at present.
Air compressor oil injection will not only affect the overall performance of air compressor, reduce its service life, but also lead to more failures.
Therefore, when the oil injection fault occurs in the air compressor, it is necessary to find out the reason immediately and use effective methods to deal with and solve it.
