The hydraulic hose mainly consists of four parts. The most important requirement of the standard hose is to have a strong connection and excellent sealing effect to ensure its normal working function. If it is unsuccessful, we will start with the appearance and internal structure, and analyze the reasons why it cannot be used. Generally speaking, in addition to oil leakage in the buckling direction, there are three reasons for customizing straight-through hydraulic joints.
1. Bursting pipe body. According to the burst direction, pipeline burst can be divided into two ways. First, the bursting direction is located on both sides of the hose, within 25mm of the flexural grommet. The reason for the bursting in this direction is the improper manufacture or installation of the rubber tube. For example, the rubber tube is stretched and twisted together during the installation and use process. The roughness of the custom tee hydraulic joint may be lower than the minimum allowable roughness. through. Second, the ripping spacing button coat 25mm. Most of the reasons for this type of burst are excessive working pressure of the hydraulic press management system or damage to the pipe body.
2. Oil leakage from sand holes on the body of the hydraulic hose. Pipe body sand hole oil leakage is generally manifested as oil leakage or linear introduction after the vulcanized rubber bubble outside the hose. The blisters on the tube body are mainly caused by the product quality problems of the rubber tube, such as the residue in the super glue in the tube body. Part of the tube body is damaged. The problem of the tube body when ejecting the mold, etc.
3. Oil leakage at the joint. The oil leakage at the joint is mainly due to the inconsistency of the dimensional accuracy of the vulcanized rubber hose connector and the connecting interface butt to the other components, perhaps because of the mismatch between the customized hydraulic right-angle joint vulcanized rubber hose connector and the connecting connector. We should not panic if hydraulic hoses exhibit common failures. The first problem to analyze is whether the pipe body has burst, or some docking places have oil leakage. After grasping the cause of the problem, it is possible to replace the connector or pipeline with the matching dimensional accuracy to ensure that it is not easy to damage. Production at the back.
