Air leakage: there may be air leakage in the pipes, joints, valves, seals and other parts of the air compressor, resulting in compressed air leakage, and the pressure cannot rise. Common leakage points are solenoid valves, filter pressure regulating valves, gas storage tanks and so on.
Head wear: After the head of the air compressor is used for a long time, the internal leather bowl, cylinder liner, piston ring and other components will wear, resulting in reduced compression efficiency and no pressure.
Improper selection or large gas consumption: If the selection of air compressor is too small, the gas production can not meet the actual gas demand, or the gas consumption of gas equipment suddenly increases, it will also cause the pressure to go up.
The solution:
Check the leak parts: Use soapy water or leak detector to check the pipes, joints, valves and other parts of the air compressor, and repair or replace the seals in time after finding the leak point. For the leakage problem of the solenoid valve and filter regulator, it is necessary to repair or replace it according to the specific situation.
Replace the head parts: If the head is seriously worn, it is necessary to replace the leather bowl, cylinder liner, piston ring and other parts to restore the compression efficiency of the air compressor.
Re-selection or increase of equipment: If it is a problem of improper selection or large air consumption, it is necessary to re-select the right type of air compressor, or add an air compressor to meet the demand for gas.
