What should I pay attention to when installing hoses? (two).

Provide protection:

Now hose manufacturers offer various products with wear-resistant shells. Through analysis, it is found that about 80% of hose failures are caused by external physical damage, and wear is proved to be the main reason. Wear is mainly caused by repeated friction between hose and equipment surface or hose. To avoid wear, the hose should be fixed with pipe clamps so that it does not rub against adjacent surfaces. The tightness of the pipe clamp should be appropriate to prevent the hose from moving, but too tight will compress and damage the hose.

Appropriate allowance shall be reserved for the hoses on both sides of the pipe clamp to compensate for the expansion and contraction of the hoses. The sleeve can provide further protection, and the spring-like metal sleeve can protect the hose from being squeezed. Soft sleeves can prevent the hose from wearing, and some types of sleeves must be installed along the hose from the unconnected end.

There is no need to disconnect the connection at both ends of the hose when installing the sleeve with an opening along the length direction. Both types of sleeves can bundle multiple hoses together. Try to avoid the contact and friction between the hose and the machine or the driving shed, so as to prevent the outer rubber layer and the steel wire braid from being worn. In the section where mechanical friction may occur with the outside world, canvas tape or rubber tube shall be wrapped for protection.

Adapt to exercise:

In addition to torsion and wear, if the hose cannot properly adapt to the movement of the working device, it will also cause it to be damaged quickly. For example, when connected to a swingable hydraulic cylinder, the length and arrangement of the hose must be appropriate to avoid tangling or bending beyond the recommended smaller radius. When multiple lengths of hoses are arranged close to each other. And some of them will move linearly. At this time, hose conveyor should be used to keep the hoses neat, so as to avoid entanglement, torsion and mutual friction. Some special types of hose conveyors can also isolate possible external situations such as falling objects, friction, chemicals or high temperature.
