In the selection of hydraulic hose standards, we often consider a very practical question, that is, the quality of the hydraulic hose I chose, how long it can be used, and how long it can be used. This problem is also related to the failure of hydraulic hoses. In the current hydraulic system, the failure of hydraulic pipes mainly has the following performances:
A. The outer layer is torn or damaged, and the reinforcement layer has signs of friction or corrosion.
B. The hose breaks at the bend, and the hose usually remains elastic.
C. The inner rubber layer is severely damaged, swollen or blistered, or even falling off.
D. The outer layer of the hose is foamed, and the inner or outer rubber layer is foamed or softened.
E. Fine cracks appear in the inner rubber layer, but still maintain elasticity. However, no obvious cracks were seen in the joints.
F. At ambient temperature, the hose becomes hard, fragile and cracked. The outer adhesive layer showed signs of drying or zooming.
G. Under the use temperature, the inner rubber layer or the outer rubber layer cracks but still maintains softness and flexibility.
H. Burst of hose reduces life. Usually, the burst occurs suddenly, and there is no trace of wear on the steel wire and the outer rubber layer.
I. The hose has leaked, and the inner tube has been chiseled.
J. The hose breaks at the joint of the jacket.
The above listed are some common failures of high-pressure hoses in general hydraulic systems. Among these failures, they have a direct impact on the use of hydraulic hoses. In most cases, the above-mentioned hoses appear, It must be replaced, otherwise it will pose a serious threat to the safety and reliability of the entire hydraulic system.
