Use and repair of hydraulic hoses

Hydraulic hose from the high pressure steel wire braided hose and fittings components. Common damaged hydraulic hoses and fittings are bursting slider or ball nut sealing surface is damaged and so on. A hydraulic hose burst reasons (l) hydraulic hose aging, cracks, or due to prolonged sun exposure . Exposure to gasoline , diesel , etc. , so that the hose corrosion damage. ( 2 ) farm tools and other elevated to the transport position after high-speed driving on uneven pavement , hanging body severe turbulence generated in the high-pressure hose several times larger than the original shock loads , then the safety valve in an instant and hard work, forcing the soft pipe burst. ( 3 ) improper installation of  Hydraulic tube fittings hose , because twisted, bent , wire layer abrasion , corrosion or partial overload and burst . ( 4 ) error using ' punch up " position . Operating tools and downs due to the uneven ground , in the" neutral "position, the cylinder piston pressure generated by the movement over the hose pressure capacity and rupture. ( 5 ) safety valve opening pressure adjusted high , long-term overloading hydraulic hose burst . ( 6 ) automatic return mechanism distributor disorders, joystick can not jump back in time "neutral " position , the operator without promptly pulled the hose to withstand greater loads arising from prolonged burst 2. pipe joints causes of damage (l) slider nut and sealing surfaces for damage .
