Observation of failure of oil-free air compressor

With the development of science and technology, the requirements for mechanical equipment in industrial production are getting higher and higher. Now many enterprises are using oil-free air compressors to replace traditional air compressor equipment in order to ensure the quality of production. However, oil-free air compressor equipment is the same as ordinary air compressor equipment. They work continuously every time, so it is prone to problems and failures. What are the general manifestations of oil-free air compressor failures?

Oil-free air compressor failure will generally have what performance?

Poor performance 1. environmental ventilation and heat dissipation

there are three main situations in which the surrounding environment of the oil-free air compressor affects heat dissipation: first, it is too close to wall obstacles; Second, there are other heat sources near the oil-free air compressor; third, the front door and side doors of the screw air compressor fittings are open during operation, and the fan cannot form strong airflow.

Performance 2. fan tape broken or loose

when the tape breaks, the oil-free air compressor will automatically stop when it runs for about 5 minutes due to excessive temperature. If the tape is too loose, it will slip, which will reduce the fan speed and affect heat dissipation. At this time, the tightness of the fan tape should be replaced or adjusted.

Performance 3. exhaust pressure is too high

when the exhaust pressure exceeds the rated 12MPa, long-term operation will automatically stop due to excessive load on the compressor and diesel engine. At this time, first check and adjust the pressure valve, and then check the diesel engine throttle control system and exclude this fault.

Performance 4. oil and gas separator filter element is too dirty

when it is too dirty, the oil will affect the circulation due to excessive resistance, causing overheating and shutdown. This situation is judged from the pressure difference before and after loading. When the pressure difference at both ends is 3 times or more of the pressure difference at the beginning of the startup and reaches 0.1MPa, it should be cleaned or replaced.

If you find that your oil-free air compressor has the above performance, we need to find the right way to deal with it, otherwise it will affect the normal operation of the oil-free air compressor and the production schedule of the enterprise.
