In the process of driving the mixing machine, we will encounter the situation that the oil alarm light is on. How can we solve this problem? Let's take a look at the common fault causes and solutions.
Failure Analysis and Solution of the Engine Oil Warning Light on the Agitator
1. First of all, the solution to the problem of insufficient oil is to check the oil level in the oil pan every day to ensure that the oil level is normal. If insufficient oil is found, it is necessary to add oil of the same model produced by the same manufacturer.
2. When the oil pump is worn, and the clearance between the oil pump shaft and the bushing, the clearance between the gear end face and the pump cover, the clearance between the gear side or the radial clearance is too large due to wear, the oil volume will be reduced and the oil pressure will be reduced. At this time, the worn parts should be replaced and the inner surface of the pump cover should be ground to restore the clearance between the worn parts and the gear end face to the standard range.
3. The oil pump does not rotate. The solution: replace the damaged flat key or filter collector.
4. The engine oil temperature is too high. If the engine cooling system has too much scale, poor heat dissipation, long-time overload operation, or the fuel supply time of the fuel injection pump is too late, the engine will overheat, accelerate the aging, deterioration, thinning of the engine oil, leak from various fitting gaps, and the pressure will drop. At this time, the scale shall be removed in time, the oil supply time shall be adjusted, and the engine shall work within the rated load.
5. The fit clearance between the main bearing and the connecting rod bearing increases. After the engine has been used for a long time, the fit clearance between the main crankshaft and the connecting rod bearing gradually increases. With the increase of leakage, the oil pressure decreases. At this time, the crankshaft can be ground, new connecting rod bearing and main bearing can be selected, and the fit clearance can be restored.
6. The oil radiator leaks oil, which will pollute the engine surface and reduce the pressure; The internal leakage makes the engine oil enter the water tank, the cooling effect of the cooling system becomes worse, the engine overheats, the engine oil becomes thinner, and the pressure drops. Remove the radiator, repair or replace it, and restore its function.
7. When the pressure sensor fails or the oil passage from the main oil passage to the pressure sensor is blocked and the oil flow is not smooth, the oil pressure will drop. The following inspections can be made: the engine runs at idle speed, loosen the oil pipe connector, observe the oil flow, determine the fault location, replace the pressure sensor or clean the oil passage.
This is the end of the abnormal analysis of the oil alarm light of the agitator. We have learned about it from seven aspects, and more relevant matters will come to our website http://www.zkhntjbj.com consulting service
