Screw air compressor is the mainstream of the development of air compressor products, with superior and reliable performance, its operation of small vibration, low noise, high efficiency, no wearing parts. But in the use of air compressor, may because of improper operation, the installation of the wrong parts, or serious blockage caused by oil injection fault.
Air compressor injection refers to the air compressor inlet outward injection of oil. Generally occurs in the case of sudden shutdown, such as the loss of power of the air compressor or manual emergency shutdown, this time and space compressor suddenly shut down and did not open the release valve in time to exhaust the air compressor oil and gas barrel of the residual gas, if the inlet check valve is too late to close, the air compressor inlet will spray lubricant.
2, screw air compressor oil injection treatment method: first should check the oil break solenoid valve has no fault, if the oil break solenoid valve is normal, should further check the main exhaust pipe check valve whether timely closed or closed is normal, if there is a fault should be eliminated.
At present, double-screw air compressor is generally no longer installed oil solenoid valve, so the main reason for oil injection is the reverse valve. Reverse check valve is recommended to use stainless steel valve, because compressed air contains water, the common iron valve oxidation corrosion speed is very fast, easy to cause the reverse check valve corrosion card and closed lax. Once the power, the role of the solenoid valve, intake butterfly valve closed, preliminary isolation. However, the inlet butterfly valve usually has a vent or clearance, which cannot be completely isolated from the outside. The hammer check valve is closed in an emergency, which is the most effective and final measure to prevent oil injection. Because the present twin-screw air compressor generally does not install the oil valve, shut down through the check valve partition, pressure to the host oil in the machine internal pressure relief into zero, gravity flow back to oil and gas barrels, heavy hammer type check valve is the most effective way.
Injection of air compressor not only affects the overall performance of the air compressor, reducing its service life, but also leads to more failures. Therefore, when the air compressor oil injection fault, immediately find out the cause, and use effective methods to deal with the solution.
