1. Cut off the oil. When the oil is cut off, the oil pump will generally squeal. At this time, immediately stop the machine and check if there is no oil in the oil tank. It is best to install a fuel cut alarm device in the fuel tank, or observe the fuel consumption of the fuel mark on the fuel tank regularly to avoid damage to the oil pump due to fuel cut.
2. The oil quality is poor, the water content is high, and there are many mechanical impurities. This is also the main reason why oil pumps are often easily damaged, so filtration should be strengthened, cleaned regularly, and the oil tank should be drained regularly. When entering the oil, check the oil product inspection report to see if it meets the burning conditions of the burner.
3. The oil pump is of poor quality. This may be experienced by anyone in the burner business. The quality of the oil pumps equipped on the burners is far from that of the earlier ones.

4. There is gasification in the pipeline. At this time, the pump pressure of the oil pump is often unstable. When the pump pressure is found to be unstable, it should be stopped immediately for dehydration and exhaust treatment.
5. Some small units mistaken the three-phase electrical phase during circuit maintenance, causing the burner oil pump to reverse and damage the oil pump. Of course, this phenomenon rarely occurs, but not without.
6. Human Factors. Some operators remove the gear of the oil pump when cleaning the oil pump. If the assembly is not good, it is easy to damage the oil pump. In fact, just clean the filter inside the oil pump. If you have conditions, you can also use diesel to burn for a while, and you can also clean the oil pump, clean the pipeline, and clean the nozzle.
