Treatment Of Yuchai Generator Problem

In the operation of the diesel engine, a mechanical fault occurred, resulting in the damage of the basic components, leading to the occurrence of major mechanical accidents. Under normal circumstances, the diesel engine before the failure of diesel engine, engine speed, sound, exhaust, water temperature, oil pressure and other aspects will appear abnormal phenomenon, that is, the characteristics of the fault. Therefore, the operator should make a correct judgment according to the characteristics of the omen and adopt the decision method to prevent the occurrence of accidents.

1. Working in the "flying car" fault warning sign, the diesel engine generally has blue smoke, burning oil or unstable speed.

Treatment methods: one is to close the throttle, stop the oil supply, step on the brake; The second method is to block the intake pipe and cut off the air. Third, fast release high-pressure tubing to stop oil supply; Fourth, the engine can be used for heavy load (braking) running in a diesel engine, so the engine will lose power due to a lack of torque.

2. Portent characteristics of viscous cylinders.

Stick in the case of serious water shortage in the diesel cylinder, rubber cylinder engine before operation, the water temperature table shows beyond 100℃, a few drops of cold water on the body, there is a "hissing" sound, white smoke, water droplets transpiration quickly.

Method: Idle operation for a period of time or stall shake crankshaft to assist cooling water temperature down to about 40℃, gradually add water, water. Pay attention not to add cooling water immediately, otherwise, when the local temperature suddenly drops too fast, it will lead to deformation or cracking of mechanical parts.

3. Characteristics of project cylinder failure warning.

Forming knife knife cylinder big mechanical problems, in addition to the valve cylinder cylinder to drop, mainly because of the connecting rod bolt looseness, connecting rod bolt looseness or after stretching, connecting rod bearing clearance cooperation are added, then the crankcase parts can hear the "click" development, use changes from small to large, * * connecting rod bolt loss or damage after thoroughly, connecting rod bearing cap, broken body and related parts.

Treatment method: immediately stop repair, replace the new.

4. Warning signs for burning tiles.

Diesel engine speed suddenly reduced, load added, the engine is black smoke, oil pressure drop, crankcase has "chirp" dull conflict sound.

Treatment: immediately stop, disassemble and check the connecting rod bearing, find out the reason, repair and replace.

5. Prediction characteristics of cracking shaft.

When the diesel engine crankshaft journal hidden fatigue crack shoulder, the symptoms are not clear, the crack expansion is intensified, depressed use occurs in the engine crankcase, speed attack intensified, engine smoke, soon after, gradually use to add, the engine produces vibration, crankshaft cracking, immediately closed.
