Service

Screw air compressors are widely used in various industries due to their high efficiency and reliability. However, like any other machinery, they are prone to faults and breakdowns. In this essay, we will discuss some of the most common faults of screw air compressors and the maintenance methods used to fix them.

1. Oil Leakage

Oil leakage is a common issue in screw air compressors. It can occur due to various reasons such as a worn-out oil seal, loose bolts, or damaged gaskets. To fix this issue, the first step is to locate the source of the leak. Once identified, the faulty part should be replaced or repaired. Regular inspections of the oil seals, bolts, and gaskets can help prevent oil leakage.

2. Overheating

Overheating is another common problem in screw air compressors. It can be caused by several factors such as low oil levels, clogged air filters, or faulty thermostats. To fix this issue, the compressor should be shut down immediately to prevent further damage. The cause of the overheating should be identified and addressed accordingly. Regular maintenance of the compressor, including changing the oil and air filters, can help prevent overheating.

3. Low Pressure

A drop in pressure is a common issue in oil-free silent air compressor. It can be caused by a clogged air filter, a damaged or worn-out compressor valve, or a malfunctioning pressure switch. To fix this issue, the compressor should be shut down, and the cause of the low pressure should be identified. The faulty part should be replaced or repaired accordingly. Regular cleaning of the air filter and proper maintenance of the compressor can help prevent low pressure.

4. Abnormal Noise

Abnormal noise is a common issue in screw air compressors. It can be caused by various factors such as loose components, damaged bearings, or worn-out belts. To fix this issue, the compressor should be shut down, and the source of the noise should be identified. The faulty part should be replaced or repaired accordingly. Regular maintenance of the compressor, including tightening loose components and replacing worn-out belts, can help prevent abnormal noise.

In conclusion, screw air compressors are essential machinery in various industries. However, they are prone to faults and breakdowns. Regular maintenance and inspections can help prevent these issues. In case of a fault, the compressor should be shut down immediately, and the cause of the issue should be identified and addressed accordingly. By following these maintenance methods, the lifespan and efficiency of the compressor can be extended.
