Drivers a ring, gold throughout two thousand &;
, the excavator is the user's production tools, money maker, once appear, fault will face economic loss, if the fault is not handled correctly, the loss will be more serious.
So, what are the common faults excavator, after these problems how to deal with?
Excavator common troubleshooting guide a, engine common malfunction and maintenance common faults and maintenance proposal 1.
Complete engine speed increase after the warm-up, engine oil alarm in the face of this situation, we usually adopt the following steps in turn to solve: filling the oil to the oil level, consider replacement oil filter cartridge, check tubing or tapping oil leak, change the CPU controller.
Had steam overflows from the top of the radiator pressure valve, water level alarm lights when the radiator top pressure overflow with steam valve, water level alarm when the light is bright, want to consider to add coolant and check for leaks, then adjust the fan belt tension, cleaning of the cooling system inside, clean or repair radiator, check the thermostat, tighten the radiator cover or replace the oil seal, replace the CPU controller.
Can't start the engine, and start the motor working properly when excavator start motor work is normal, and the engine does not start, the first thing to consider refueling, if still can't start the engine, so want to consider to check whether there is air leaking fuel system, then check the high-pressure pump in turn or nozzle, valve clearance and engine compression pressure.
Exhaust into a white or blue white or blue, if it is found that equipment exhaust oil should first adjust the volume to the appropriate levels, if there is no obvious improvement, will be expected to oil change as required.
Sometimes when the exhaust in black when equipment exhaust in black, first of all to clean or replace the air filter cartridge, then check the nozzle, check engine compression pressure, finally to clean or replace the turbocharger. 6.
Sound sometimes is not normal if it is found that the engine combustion, the voice is not normal phenomenon, you need to check the nozzle in a timely manner.
The engine sound abnormal sound when the engine is not normal, first check the fuel is in line with the requirements, then check whether the engine is overheating, replace the silencer, adjust the valve clearance.
God steel excavator two common faults and maintenance suggestion 1, electrical system.
The engine at high speed, charging indicator light is still on when the engine at high speed, if the charging indicator is on, you will need to check the generator and power lines, if the problem is still the end, the need to change the CPU controller.
The generator abnormal sound when the generator abnormal sound, please carefully check the generator immediately.
Switch to spin & other
Start & throughout;
Position, start the motor does not turn when opened and spin to & other;
Start & throughout;
Position, start the motor does not turn, first consider check repair the wire, then consider to the accumulator, check the starter motor, check the safety relay, finally consider the replacement CPU controller.
Start the motor cannot easily start the engine if the starter motor does not start easily engine, first please recharge battery, if the problem not solved, when check the starter motor has a problem.
Before starting the engine start motor loosen if before starting the engine start motor, want to consider to check repair the wiring, then consider giving the accumulator.
Start switch in & other;
Position, the engine oil pressure light not on.
If the engine does not start, start switch in & other;
Position, the engine oil pressure light is not on, then you will first need to check the monitor, if the problem is not solved, want to consider to check and repair the wire.
Monitor the keyboard doesn't work monitor the keyboard doesn't work, please turn off the power supply, reopen after 5 seconds.
Third, other common faults and maintenance advice 1.
Driving wheel excessive wear, excessive wear, driving wheel of crawler tension is not excessive wear driving wheel of crawler tension is not enough when excavator, track tension is not enough, to timely adjust the crawler tensioning degree, avoid the happening of the accident.
Scoop up slowly or exercise Volvo excavator bucket up slowly, or slow movement if digging bucket rise or not movement, is likely to be enough hydraulic oil, then consider filling the hydraulic oil to the specified location.
Abnormal sound from the pump if abnormal sound heard hydraulic pump, first consider cleaning hydraulic filter tank.
Hydraulic oil temperature is too high, too fast when excavator hydraulic oil temperature is too high temperature, heating up too fast, the first to clean the hydraulic oil cooler, and then adjust the belt tension, add the hydraulic oil to suitable location.
