摘要
叉车货叉下滑量、门架自倾角和超载安全性达不到技术条件要求的主要原因是原多路换向阀存在缺点。采取的主要改进措施是改用合理的新加工工艺,保证滑阀与主阀孔的配合同心度,采用新型组合式密封;改进安全阀阻尼孔等。
The unsatisfaction of technical requircments, such as fork settlement, mast self-inclination and overload safety, is mainly due to the shortcomings of multiported directional valve. The measures of modification include improvement in machining technology to ensure quality of fit between spool valve and main valve hole, application of new integrated sealing and improvement of safety valve damping orifice.
