The quality of the hydraulic rubber hoses is directly related to the safety and economy of the use process. The hydraulic rubber hoses of poor quality usually have problems such as uneven thickness of the hose, too loose or too tight steel wire reinforcement layer, and large deformation after pressurization. Therefore, it is crucial to choose a good quality hydraulic rubber hose. Here are four ways to help you identify the quality of your hydraulic rubber hose:
First, you need to see the overall appearance of the hydraulic rubber hose. If the outer rubber layer can see obvious pores and damage, causing the steel wire reinforcement layer to be exposed, this is an obvious low-quality hydraulic rubber hose. It is also necessary to see whether the cross section of the hydraulic rubber hoses is a perfect circle and whether the wall thickness is even. If there is a deviation from the center of the circle and the deviation of the wall thickness is large, it may cause partial rupture during high pressure work and affect the use.
Secondly, the condition of the steel wire reinforcement layer should be observed. It is necessary to observe whether the distribution of the steel wire is even and the degree of adhesion with the rubber layer. The high adhesion force can better meet the requirements of the crimping of hydraulic rubber hoses joints.
In addition, you also need to observe the elasticity and smoothness of the hydraulic rubber hose. You can press the inner rubber of the hydraulic rubber hoses and bend the hoses with your fingers to see if it has good elasticity. Good elasticity means high rubber content and better quality.
The measurement of hydraulic rubber hoses mainly requires measuring the inner and outer diameters, so as to observe whether the size meets the requirements and whether the wall thickness is even. If the deviation exceeds the allowable range, it will have a great impact on the installation and use of hydraulic rubber hoses joints.
Smell whether the hydraulic rubber hoses itself have abnormal smell. If there is abnormal smell, it means that the rubber used in the hoses is recycled material. This kind of hoses are often insufficiently vulcanized during the manufacturing process, which seriously affects the quality of the hoses.
Testing is a very objective and intuitive way to identify the quality of hydraulic rubber hoses. The tests required to inspect the hydraulic rubber hoses include: pressure test, bending test, leakage test, deformation test and impulse test. Carry out the above tests to obtain the most intuitive reports, and it is more convenient to distinguish the quality of the hydraulic rubber hose.
The above are the four methods for the quality identification of hydraulic rubber hoses. Select qualified products to ensure the safety of users, and we provide high quality hydraulic rubber hoses, if you have any needs you can contact our sale manager for detailed inquiry.
