Screw air compressor in the loading state does not pump, there are a variety of possible reasons. First of all, it is necessary to check whether the air inlet of the air compressor is unblocked, because the blocked air inlet will prevent air from entering the compressor, thereby affecting its pumping ability. Secondly, if the filter device of the air compressor, such as the air filter, is not cleaned or replaced for a long time, it may also cause poor air intake due to blockage, which will affect the pumping effect.
In addition, the internal parts of the screw air compressor, such as screws, bearings, etc., if worn or damaged, will also reduce its pumping efficiency. At the same time, the sealing performance of the compressor is also an important factor affecting the pumping effect. The sealing is not tight, which may lead to gas leakage, thereby reducing the pumping pressure.
In addition, it is necessary to consider the setting of the air compressor. For example, improper setting of the pressure switch may cause the air compressor to stop pumping when the preset pressure is not reached. At the same time, problems in the electrical control system, such as the failure of contactors, relays and other components, may also affect the normal operation of the air compressor.
In summary, the screw air compressor loading does not pump the reason may involve the air inlet blockage, filter device blockage, internal parts wear, poor sealing performance and set or electrical control system problems and other aspects. In order to accurately find out the problem, it is recommended to conduct a comprehensive inspection of the air compressor and take corresponding maintenance or replacement measures according to the actual situation.
