PU steel wire hose has three connection methods
It is a well-known fact that the high-pressure oil hose is a consumable item. However, if it is used incorrectly, its consumption rate will soar. As a professional manufacturer of high-pressure hoses, Orientflex has summarized several common misuses that are often overlooked:
Exposure to frequent and severe pressure surges
Typically, the bursting of high-pressure hoses is seldom due to excessive static pressure; rather, it is closely tied to the intensity and frequency of pressure surges. When construction machinery is in operation, sudden increases or decreases in oil pressure occur repeatedly within the oil hose. This leads to frequent pressure shocks, which in turn exacerbate the damage to oil seals throughout the system, cause blistering and cracking of the hose, and result in loose joints and leakage phenomena. Therefore, during operation, it is crucial that the valve rod be manipulated gently and not yanked forcefully.
Excessively high operating temperature of the oil
As construction machinery operates, the hydraulic system heats up the oil due to power dissipation, and coupled with the influence of external temperatures (particularly in summer), the oil temperature can skyrocket. The higher the oil temperature, the faster the rubber ages, leading to poorer elasticity, diminished strength and sealing performance, and a rapid increase in the likelihood of the hose bursting. Hence, during operation, if the temperature rise of the hydraulic system is too high or too rapid, the root cause must be promptly identified and rectified. In summer operations, especially during continuous use, necessary cooling measures should be implemented.
Unreasonable selection and installation of the oil hose
When replacing a high-pressure hose, it is essential that the length of the hose, the number of steel wires, the shape and size of the joint be carefully considered and made reasonable. Minimize the degree of bending of the hose as much as possible. When tightening the joint nut, take care not to distort the hose, as excessive bending and distortion will drastically reduce its service life. Additionally, protective measures should be implemented on areas prone to friction to prevent the hose from bursting due to wear.
We hope that everyone will pay heed to these points when using high-pressure oil hoses to avert premature damage caused by improper use. By following these guidelines, you can extend the lifespan of your hoses and ensure the efficient operation of your machinery.
