The bursting of hydraulic oil pipes is a headache for many equipment users. After a pipe burst, hydraulic oil will leak, affecting the operation of the equipment. So, why do pipes burst, and what should be done to minimize losses after a burst? Next, I'll tell you how to avoid pipe bursts.

1. Using inferior oil pipes

Many people, when replacing the original oil pipe after it's damaged, choose inexpensive and unknown hydraulic oil pipes to save money. As a result, the quality is inferior to the original hydraulic oil pipe, and the reliability is low. If the hydraulic oil pipe is damaged due to this, it can only be blamed on oneself.

2. Excessive pressure in the hydraulic system

The hydraulic system has its appropriate preset pressure. When the pressure is too high, exceeding the original preset pressure of the hydraulic oil pipe, the probability of a pipe burst will increase. The solution is to measure the pressure value of the main pump during operation and appropriately adjust the pressure in the multi-way valve.

3. High temperature of hydraulic oil

The physical property of thermal expansion and contraction cannot be avoided in your equipment. The high temperature of the hydraulic system will affect the sealing of hydraulic components. The deformation of hydraulic parts due to high temperature will cause the valve body to get stuck, creating local high pressure and leading to a pipe burst.

4. Mixing different types of hydraulic oil

The hydraulic oil pre-installed in the equipment after use is different from the commonly available hydraulic oil types on the market. Adding different types of hydraulic oil without knowing this will lead to unstable properties of the hydraulic oil, damage the hydraulic system, and easily cause pipeline leakage.

5. Bad operating habits

Many equipment users operate the machinery roughly, generating an instantaneous impact force within the hydraulic system. This instantaneous impact force acts on the weak points of the hydraulic system, greatly reducing the service life and causing frequent problems with the equipment. Therefore, the operation should be gentle during work, and high-intensity operations should be avoided.

6. Corrosion on the outer side of the hydraulic oil pipe

Nowadays, hydraulic oil pipes are treated for corrosion resistance in terms of materials and processes. However, the hydraulic oil pipe is essentially a rubber product. Long-term contact with oil stains and diesel will damage the structure of the hydraulic oil pipe itself. Usually, the stains on the excavator should be cleaned frequently to avoid damage to the excavator.

7. Abnormal vibration of the hydraulic pipe

As long as the hydraulic pump is working, it will generate vibration, which will be transmitted to the hydraulic oil pipe. This long-term vibration will cause fatigue wear of the hydraulic oil pipe and lead to damage. The excavator should be checked regularly to avoid the loosening of the pipe clamps and protective sleeves of the hydraulic oil pipe, which may wear the pipe.

What should be done after the hydraulic oil pipe bursts?

When the oil pipe bursts during operation, first lower the equipment and turn off the machine in a timely manner to reduce the pressure in the hydraulic system and avoid losing more hydraulic oil.

When it's not possible to replace the hydraulic oil pipe in a timely manner, industrial glue and tape can be used for temporary sealing. At the same time, the damaged hydraulic oil pipe can be used to replace other oil pipes with lower pressure to reduce losses.

The bursting of hydraulic oil pipes is something that no one wants to see. Therefore, choose oil pipes from big brands to ensure that all parameters are within a reasonable range. Usually, clean them in a timely manner. Only by taking good care of it can it better exert its performance!
