Oil-free air compressor common faults and maintenance methods?

Q: Oil-free air compressor common faults and maintenance methods?

Answer:

oil-free air compressor common faults include:

leakage: Check whether the gas supply pipeline, one-way valve, safety valve, pressure switch and other joints are leaking. If gas leakage is found, it must be dealt with in time.

Head cup wear: general cup life of about 3 years, expired must be replaced.

Exceeding the rated flow or overloading the machine may also cause the oil-free air compressor to malfunction.

For the maintenance of oil-free air compressors, the following methods can be adopted:

regularly check and replace the air intake filter core to ensure the normal operation of the oil-free air compressor. If the filter core is seriously fouled, it will increase the air intake resistance and affect the air pressure. In addition, it is necessary to check whether the suction pipe has a longer and thinner pipe to minimize the suction resistance.

Check whether the check valve, air valve, etc. are faulty, because the failure of these parts is usually caused by indentation, cracks, spring breakage, etc. on the valve plate. At the same time, check the fastening of the fasteners and the degree of wear of the wear parts, and replace the wear parts.

Check whether the exhaust pressure is normal. Too low exhaust pressure is usually caused by clogging of the air filter, too long suction pipe or pipe cracking, which must be checked and adjusted in time.

Check whether the oil-free air compressor is overheated. If it is overheated, it may be caused by high exhaust temperature, insufficient lubricating oil or insufficient cooling water. In this case, the cooling system must be checked and the lubricating oil or cooling water must be replenished in time.

As an oil-free air compressor, the water-lubricated air compressor of Shanghai Granklin Group also needs to pay attention to the common faults and maintenance methods mentioned above. At the same time, because it uses water as a lubricating and cooling medium, it does not need to use lubricating oil. Therefore, during the maintenance process, it is necessary to regularly check the quality of the water and replace the water to ensure its normal operation and extend its service life.
