In the choice of hydraulic hose, we often consider a very practical problem, that is, the hydraulic hose I choose, what is the quality, how long it can be used. This problem is related to the failure of the hydraulic hose. In the current hydraulic system, the failure of hydraulic hoses mainly has the following performances:
A. The outer layer is torn or damaged, and the reinforcing layer shows signs of friction or corrosion.
B. The hose breaks in the bend and the hose usually remains elastic.
C, the inner rubber layer is severely damaged, swelling or stratification, or even falling off.
D. The outer layer of the hose is foamed, and the inner rubber layer or the outer rubber layer is foamed or softened.
E, the inner rubber layer appears fine cracks, but still maintains elasticity. However, no obvious cracks were observed in the joint portion of the joint.
F. At ambient temperature, the hose becomes hard, brittle and cracked. The outer layer has signs of drying out or zooming.
G. At the temperature of use, the inner rubber layer or the outer rubber layer cracks but remains soft and flexible.
H, the hose burst, reducing the life. Usually, the burst occurs suddenly, and there is no trace of wear on the wire and the outer layer.
I. The hose leaks and the inner tube has a trace of being chiselled.
J. The hose breaks at the joint of the jacket.
Listed above is a common manifestation of the failure of hydraulic hoses in general hydraulic systems. These faults have a direct impact on the use of high-pressure hoses. The hose in the above situation must be replaced as soon as possible. Otherwise, it poses a serious threat to the safety and reliability of the entire hydraulic system. Usually, after the above situation occurs, we will quickly find out which line of the entire system the fault is present. Analyze what role this pipeline takes. Then we will think about the reasons and propose specific measures to solve the problem.
