If there is enough diesel in the fuel tank of the generator set, the diesel generator set may usually be equipped with a self-protection device. When the oil pressure is too low, it will automatically stop. the oil level of the diesel engine. If the oil level is normal, it is possible that the diesel engine oil pump is faulty or the leak somewhere is too large, preventing the oil pressure from building up if it still cannot be eliminated. , you can ask.
Troubleshooting the fault cause:
According to common practice, it is generally believed that the oil system of Cummins diesel generator is caused by air, blockage or loose seal. However, when it comes to a specific diesel generator, maintenance personnel should first check the oil system, filter element and other related components, no engine leaks or defects.no deadlock found; . have been checked and no problems found; in addition, valve clearance, injection advance angle, etc. of the diesel generator were also checked and adjusted to determine the fault. The phenomenon still exists.
Analysis of the causes of failure:
Then the technical staff analyzed that the check valve of the generator was not damaged, but only a little dust or dirt. dust particles adhered to the one-way engine oil return valve. The steel ball and sealing belt of the valve are on the upper surface, which prevents the valve from closing tightly, which will cause the generator set to fail in operation. It sounds simple, but it took several days from when the problem occurred to when it was resolved. In fact, I first suspected that there was something wrong with the h return bolt.oil, but when I pumped oil with a manual oil pump, I felt that the pressure in the oil system was basically normal, and there was also a clear oil return. noise coming from only the oil return bolt.
