登車橋 http://www.8kvv.com/負載主要表現(xiàn)為活塞桿停位不準(zhǔn)

、推力不足、速度下降

、工作不穩(wěn)定等

，登車橋液壓缸內(nèi)部泄漏包括液壓缸體密封、活塞桿與密封蓋密封及活塞密封均磨損過量等引起的泄漏

；钊麠U與密封蓋密封泄漏的原因是，密封件折皺

、擠壓

、撕裂、磨損

、老化

、變質(zhì)、變形等

，此時應(yīng)更換新的密封件

。
Ramps load mainly for piston stop bit inaccurate, insufficient thrust, slow down, job insecurity, etc, Ramps internal leakage of hydraulic cylinders including hydraulic cylinder seals, rod seals and piston seals and closures are excessive wear etc. caused by the leakage. Cause the piston rod and the sealing cap seal leaks, the sealing member wrinkle, crush, tear, abrasion, aging, deterioration, deformation, etc., we should replace with new seals.

登車橋 http://www.8kvv.com/活塞密封過量磨損的主要原因是速度控制閥調(diào)節(jié)不當(dāng)，造成過高的背壓以及密封件安裝不當(dāng)或液壓油污染

。其次是裝配時有異物進入及密封材料質(zhì)量不好

，其后果是動作緩慢、無力

，嚴(yán)重時還會造成活塞及缸筒的損壞

，出現(xiàn)“拉缸”現(xiàn)象。處理方法是調(diào)整速度控制閥

，對照安裝說明應(yīng)做必要的操作和改進

；清洗過濾器或更換濾芯、液壓油

。
Ramps piston seal wear is mainly due to excessive speed control valve regulating properly, resulting in excessive back pressure and a seal improperly installed or hydraulic oil contamination. Followed by a foreign substance enters the assembly and sealing materials quality is not good, the consequences are slow, weak, can also cause serious damage to the piston and the cylinder, a "pull-cylinder" phenomenon. Approach is to adjust the speed control valve, the control installation instructions shall make the necessary operation and improvement; cleaning the filter or replace the filter, hydraulic oil.
