1. High temperature or high temperature fault shutdown
Inferior oil or bad oil, lack of oil; blockage of oil filter or oil circuit; failure of fan motor (contactor failure); blockage of air filter; failure of temperature sensor; poor heat dissipation of cooler or blockage of heat sink; failure of temperature control valve ; the host is damaged.
2. The whole machine consumes a lot of fuel
High oil content in non-exhaust: leakage of lubrication pipeline or failure of seals; high oil content: whether the oil return pipe is unblocked; oil level is too high; long-term low-pressure operation; oil failure; oil emulsification or deterioration; precision filter failure; excessive loading and unloading frequently.
3. Electrical failure
Whether the electrical parts work normally (high voltage, low voltage, bad contactor); motor failure; poor contact of the power switch.
4. Abnormal shutdown
Non-overload shutdown: high temperature shutdown, power failure, loose wiring, loop relay or fuse failure. Overload shutdown: Exhaust pressure is too high, thermal relay failure, lubricating oil viscosity increases, main motor failure, motor or contactor wiring is loose, main engine failure, set value is too small.
During maintenance, be sure to turn off the power and completely relieve pressure.
