Hydraulic hoses play a key role in many hydraulic machinery, and their effects on the guidance of hydraulic oil cannot be ignored. In fact, hydraulic hoses may also leak oil during continuous use, so what is the reason for this?
1. There is a problem when working. When the hydraulic press is working, the joint part of the hydraulic hose is broken and loose. This situation is more common. Therefore, it is recommended to check the joint part of the hydraulic hose when the hydraulic press is running to avoid the hydraulic pressure caused by the problem of the joint part. Oil leaking hose.
2. The sealing part of the hydraulic hose has been aging. The hydraulic machine has seals such as oil seals and seals. These parts are prone to some aging phenomena. Therefore, it is recommended that you check regularly to avoid leakage. It is also what we need to pay attention to when using hydraulic hoses. place.
High-pressure hose
In relatively cold winter conditions, cracks in the outer surface can cause the rubber hose to twist. If you find cracks on the outer surface of the rubber hose, you should pay attention to observe whether the rubber hose has cracks, and decide whether to replace the rubber hose immediately. Because the load-bearing capacity of the hose depends on the steel wire reinforcement, which is the skeleton of the hose, usually braided and surrounded by steel wires. HV and EHV are mostly braided from multiple layers of steel wire and surround the frame. The low-pressure hose is woven with cotton and hemp instead of steel wire, and is generally used for low-pressure oil return pipelines. Temperature has a great effect on rubber hoses.
Therefore, do not move the hose or disassemble and repair the hydraulic system at will in a cold environment to ensure the safety of the hydraulic hose, if necessary, it should be done indoors. If you need to work in a colder environment for a long time, replace the anti-icing hose. Finally, whether the outer rubber layer of the hydraulic hose is damaged or whether the inner and outer surfaces are defective, we need to be careful to avoid small problems causing big problems.
