Engine high-pressure oil pipe fracture reason:

The high-pressure oil pipe of the engine and other high-speed running machinery is fastened at the end of the injector and the end of the fuel injection pump by a screw sleeve at both ends and suspended in the middle. Engine and other power machines are inevitably accompanied by strong vibration in the working process, so the high-pressure oil pipe is easy to fracture at the fastening place of both ends. The common high pressure oil pipe only has the simple round hole male sleeve, the high pressure oil pipe vibrates in the screw sleeve inner hole end part to receive the strong interference, then will produce the high frequency cutting stress in the contact with the oil pipe, sometimes will cause the oil pipe to break in the short time.
