Causes of hose failure and how to deal with it

1. The cracking of the high-pressure hose is related to the quality of the high-pressure hose and the method of machinery and equipment after the high-pressure hose. In the machine and equipment air conditioning copper pipe need to pay attention to the fact that the angle distance is too large in the connection of the high-pressure hose will cause pressure aggregation, forming the connection of the oil pipeline cracked. At this time, it is only necessary to disassemble and install the diesel pump for inspection, and then change to a fuel pump to overcome the difficulty.

2. The cracking of the high-pressure hose is necessarily related to the poor load of the oil pump. The high-pressure hose causes cracks in the pipeline based on long-term accumulation.

3. It is recommended that if the injector is stuck in the work of the machine, the hydraulic plunger pump is still on the gasoline pump again, and the high-pressure hose solves the working pressure is very limited, and the long-term acceptance of this pressure will crack. Therefore, once the diesel engine high-pressure hose is cracked, the key provision is to check whether the diesel pump is stuck.

4. The cracking of the high-pressure hose also has a great connection with the diesel engine. The high-pressure hose management only relies on the oil pipeline to clamp a galvanized iron fulcrum support point, diesel engine boom discussion will cause the oil pipeline resonance to crack the oil pipeline, like that to remove and replace the high-pressure hose is useless, you have to deal with the diesel engine before dismantling.

5. Some auto repair shop masters often find that the diesel engine high-pressure hose is cracked, and the head of the diesel pump is connected to the diesel pump on both sides of the high-pressure hose and the fuel pump tight seat of the diesel pump is tilted in orientation, after tightening the screw caps on both sides of the high-pressure hose, the high-pressure hose is crooked and bent, and after the diesel engine is recommended, the high-pressure hose cracks due to the hesitation.
