Weichai diesel generator set is a first-class diesel generator set in the generator set market. It can play a very important role in the process of enterprise use. A better diesel generator set can greatly improve the guarantee of the enterprise . Weichai diesel generator set is a kind of performance and excellent power generation equipment; it can show his value in long-term work. Weichai diesel generator set needs our simple maintenance of the generator set after 250 hours, such as The exhaust part of the connection pipeline of the diesel generator set, these are the places that we need to check. The following Feng Yue editor will briefly give you an analysis of how to troubleshoot the exhaust pipe of the Weichai generator set:

Generally speaking, the operation of the generator set is unstable after starting, and the speed is high and low, mostly due to the failure of the fuel adjustment system. Causes of failure: poor operation of each cylinder, resulting in inconsistent deflation pressures; air, moisture, or poor oil flow in the fuel supply system; the amount of fuel supplied by the plungers of the sub-cylinders in the high-pressure fuel pump is more related; the governor speed Functional problems; the governor cannot reach low speeds; the internal rotating parts of the governor are unbalanced and have large gaps; the speed of the governor does not reach the rated data.

1. Consider the problem of engine oil, low viscosity or excessive oil volume, resulting in incomplete burning and high temperature evaporation into oil and gas discharged from the exhaust pipe. At this time, you need to check the oil scale in the oil pan of the diesel engine to identify the cause.

2. Considering that air enters the oil circuit, you need to loosen the bleed screw of the high-pressure oil pump and press the hand oil pump to discharge the gas.

3. Considering the poor tightening of the tubing, use a special wrench to tighten the oil return screws of the high and low pressure tubing of the unit.

After corresponding solutions to the above three points, start the equipment, increase the speed, and check whether it is stable. If the diesel engine operation is still unstable at this time, it means that the problem is elsewhere and the investigation needs to be continued.

At this time, the problem is concentrated on the oil pump. Firstly, the high-pressure oil pipe of the upper cylinder of the oil pump is tested for oil cut one by one. If it is found which blue cylinder phenomenon is solved after the cylinder is disconnected, it is necessary to stop immediately and spray this oil cylinder. Remove the oiler and perform the injection pressure test. At this time, you must find that this cylinder has oil dripping. Take the thin copper wire to dredge the fuel injection hole, re-install and start, you will find that the smoke exhaust is normal, and the exhaust pipe problem is just solved.
