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;
Matters needing attention
1, air compressor should be parked away from steam, gas and dust. The air inlet pipe shall be equipped with a filtering device. After the air compressor is in place, it should be wedged symmetrically with a cushion block.
2. Always keep the outside of the storage tank clean. Welding or hot working near the gas storage tank is prohibited. The gas storage tank is subjected to water pressure test once a year, and the test pressure is 1.5 times the working pressure. The barometer and safety valve should be checked once a year.
3, the operator should be specially trained, must fully understand the structure, performance and function of air compressor and ancillary equipment, familiar with the operation and maintenance procedures.
4, the operator should wear work clothes, lesbians should be woven into a work hat. It is strictly forbidden to operate after drinking, do not engage in things unrelated to the operation, do not leave the post without authorization, and do not decide to replace the work with non-local operators without authorization.
