Concrete mixing plant air supply faults

1. air compressor

Check valve damage, piston ring wear, intake valve damage and air filter clogging. To determine whether check valve damage, automatic stop in air compressor after more than ten seconds, turn off the power supply, with the hand big belt wheel, if can easily turn a week, suggests that check valve is not damaged; On the other hand, the check valve is damaged. Sky press pressure rise slowly, accompanied by series oil phenomenon shows that the air compressor piston ring has serious wear and tear, it should be replaced in a timely manner. When the inlet valve damage or air filter jams, also can make the air compressor pressure rise slowly (but not series of oil).

2. faults of the pressure reducing valve

Pressure is not high, or pressure rise slowly, etc. Pressure is not high, is often caused by pressure regulating spring break or diaphragm rupture, must change new; Pressure rise slowly, is usually caused by filter blockage, should be removed for cleaning.

3. line fault

Pipeline leak, joint hose burst, condensate accumulation, etc. Pipe joint leakage and hose burst can be to judge the part of leakage from the her voice, should be timely repair or replacement; Have a condensed water accumulated in the pipe line, should be promptly eliminate, condensed water freezes easily and feature is the winter in the north block gas path.
