At present, the hydraulic oil pipes on the market are generally configured by the parts dealers according to the size and size provided by the owners. Some parts dealers find the configuration tools themselves and press the high-pressure oil pipes with the iron joints. Joints suppressed by different standards have hidden dangers. Once the vehicle hydraulic system has ultra-high pressure, it will burst from the joint or the hydraulic oil pipe itself, causing hydraulic oil to leak.
The hydraulic oil pipe has been in friction with hard objects such as the frame for a long time, causing the surface of the hydraulic oil pipe to wear out, and the wear part cannot withstand the excessive pressure and burst; the high-pressure oil pipe rubber is aging due to long-term use without replacement, and it cannot withstand the excessively high rubber. It burst under oil pressure.
Due to improper use or overloading of the vehicle, for example, when the dump truck is landing after unloading the cargo, and the carriage has not completely landed, that is, moving the hand-operated valve to the "stop" position, the hydraulic pressure will remain in the cylinder. The oil pressure of the hydraulic oil in the oil cylinder after loading the cargo will increase, and the car will bump and vibrate during driving, which makes the hydraulic oil pipe prone to fatigue damage, and even bursts suddenly when the heavy load is lifted, causing the hydraulic oil to leak. Accelerate the fall and damage the vehicle, or even cause an accident.
