Common faults and maintenance methods of automobile air compressor

Common faults and maintenance methods of automobile air compressor

1, unable to start.

The fuse is blown; Low voltage, lack of phase of power supply or poor circuit contact; The starting electrical appliance is faulty and the starting button is in poor contact; Main motor failure; The host computer has failed; The fan motor is overloaded;

2. High exhaust temperature

Insufficient lubricating oil for air compressor; Oil cooler is dirty; The oil filter element is blocked; Temperature control valve failure, solenoid valve failure, coil damage, aging or rupture of diaphragm, etc. Temperature sensor failure; Fan motor failure, cooling fan damage or excessive ambient temperature, etc.

3. High fuel consumption

Excessive lubricating oil in air compressor, oil deterioration or expired use; The oil return pipe is blocked and improperly installed; The filter element of oil-gas separator is broken, and the separator in the separator cylinder is damaged; Oil leakage and oil leakage of the unit. Low unit pressure: the actual gas consumption is greater than the unit gas production; Intake valve failure; The exhaust valve is faulty and cannot be closed during loading; Low pressure setting, pressure sensor failure, pressure gauge failure, pressure switch failure, pressure sensor or pressure gauge input hose leakage;
