Shenzhen Qiyu told the damage reason of high voltage silicon rubber tube you
![]()
(1) by the frequent and intense pressure impact. High voltage silicon hose burst, is generally not under static pressure too much, but impact and pressure related to severe degree and number. Engineering machinery in operation, will appear repeatedly hydraulic tubing in the suddenly increased or decreased, which impact on the tubing pressure seal frequent, resulting in each part of the damage aggravated, high-voltage silicon hose loose leakage foaming and rupture and pipe joint. Therefore, when in operation, the valve stem can not be too fierce, must be gentle.
(2) the use of stainless steel metal hose oil temperature too high. Operation engineering machinery, hydraulic system for power loss and make the oil heating, plus the influence of outside air temperature (especially in summer), can cause a sharp increase in oil. Oil used for higher temperature, rubber aging, elasticity variation, decreased strength and sealing performance, will soon burst hose. Therefore, in the operation, when the hydraulic system temperature is too high, too, should identify the reasons, be excluded; summer homework, especially in continuous operation, should take the necessary cooling measures.
(3) high voltage silicon tube selection, installation is not reasonable. In the replacement of large diameter high pressure silicon rubber hose, high pressure hose length selected silicon, wire layers, joint shape and size are to be reasonable, and should try to reduce the high voltage silicon tube bending degree; in tightening the union nut, don't make a high voltage silicon hose distorted, excessive bending and twisting will reduce the pressure of the silicone tube the service life is greatly; some of the easy occurrence of friction parts should take protective measures, to prevent the high voltage silicon rubber tube due to wear and burst.
