Hydraulichose damage the main reason:
Hose improper use will greatly reduce the hose life. In actual work, most of the hose damage is due to improper use.
(1) By frequent, intense pressure shocks. Hose burst occurs, generally not because of too much to withstand static pressure, but rather the severity of the impact of pressure and the number of times. Construction machinery in operation, the tubing will be repeated sudden increase or decrease in hydraulic pressure situation, which constitutes a frequent pressure on the tubing impact, leading to the Ministry of oil seal damage, hose blistering and rupture and the loose joints seepage Leakage phenomenon. Therefore, in operation, the valve stem can not be pulled too fast, must be gentle.
(2) Oil temperature is too high. Construction machinery operation, the hydraulic system due to power loss caused by fluid heat, coupled with the impact of outside temperature (especially in summer), can make the temperature rise sharply. The higher the fluid temperature, the more prone to aging bananas, flexibility, strength and sealing performance decline, the hose will soon burst. Therefore, in operation, when the hydraulic system temperature rise is too high, too fast, it should promptly identify the reasons to be ruled out; summer operations, especially in continuous operation, should take the necessary cooling measures.
(3) Hose selection, installation is not reasonable. When replacing the hose, the length of the hose used, the number of steel layers, the shape and size of the joint should be reasonable, and should be minimized hose bending; Tighten the joint nut, do not make the hose distorted, excessive bending and twisting Will greatly reduce the service life of the hose; Some prone to friction parts should take protective measures to prevent hose burst due to wear and tear.
(4) Friction leads to burst.
