How to maintain hydraulic hose?

The high-pressure hose is like the arteries of the hydraulic system, and the hydraulic oil is continuously transmitted to the various working devices. But often important things are more fragile, a set of original hydraulic pipe is expensive. In order to extend the service life of the hydraulic pipe, the most important thing is that the driver's action should be gentle when operating the excavator, and the appropriate maintenance method will also greatly affect the life of the hydraulic pipe.

1. Steel wire protective ring

Hydraulic working devices such as gear pumps, hydraulic pumps, motors will make the hydraulic pipe produce high-frequency vibration when working, this high-frequency vibration can not be completely eliminated, so it is necessary to install a protective ring outside the hydraulic hose.

2. Don't rub

Some excavator hydraulic hose is later equipped with their own, the length and fixed parts are not suitable, it is easy to friction with the big arm, or the mutual friction and bending between the pipes, resulting in local thinning of the outer wall, under the action of high pressure, it is easy to burst the pipe phenomenon.

3. Do not touch steam and diesel

Try not to let the hydraulic hose contact steam, diesel, although the hydraulic hose is oil-resistant, but long-term contact will cause the rubber to swell, crack and lose elasticity.

4. Grease the interface

The central rotary joint, as well as the metal joint of the high-pressure tubing, can be applied with butter or oil-resistant sealant after the surface treatment is clean to avoid rust in these places.

Brief summary

The quality of the original factory's oil hose must be absolutely accurate, the current market to do the oil hose, the quality is different, the technology of the oil jhose business and the quality of the oil hose are uneven, resulting in the life of the oil hose is different. Clamping technology and equipment, this is the key to the length of tubing life. The clamping technology is difficult to master, and the clamping force is large and small. The clamping of the original hose can not be done with the ordinary hose locking machine, and most hose crimping machines on the market can not do the effect and quality of the original factory. Therefore, in order to extend the life of the hydraulic hose, we must pay attention to the above maintenance measures.
