装载机分配阀的再制造修复

Remanufacuring Repair In Distributing Valve of Wheel Loader

分配阀作为装载机液压系统控制元件之一,其损坏造成装载机工作装置无法正常工作。分配阀的典型失效是阀孔和阀杆的磨损和拉伤,只要解决阀杆和阀体孔的修复问题就能实现分配阀的修复。经过分析,按照一定的修复流程和工艺方法,分别对阀体进行珩磨和阀杆电镀的再制造修复,然后重新装配和通过出厂试验,就能保证再制造分配阀的性能不低于新件的质量水平,延长其生命周期,实现资源的重复利用,经济和社会效益巨大。

Distributing Valve is one of the hydraulic system controling components of Wheel loader,Its failure makes working device can＇t work normally.Its typical failure mode is scratches on the valve body or on the spools,we can solve the repair problem of the valve as long as we can repair the valve body and the spools.By analysis we can reman them according to some processes and technologies,we reman respectively the valve body by honing and the spools by plating,then assembly again and pass the tests,guarantee the performance of reman distributing valve not less than the level of quality of new parts,extend its life cycle and realize the recycle of resource,it＇ll do great contribution to the economy and society.
