翻开国产注塑机液压州路图册,不难发现目前国产注塑机所用的电液(磁)换向阀中位机能绝多者为“O”型、“Y”型,而“N型”、“H”型、“J”型等则用得极少。与国产注塑机有过一段接触的人都有这种体会,即在所用的液压件中,电液(磁)换向阀的使用寿命较短,这里一个重要的原因是其工作较为频繁,阀芯与阀体接触面积大,导致磨损率大,一旦阀体内泄漏增大该阀就失去其功能了,对于塑料制品生产厂家来说,一般是无能力将其磨损间隙修复
Open domestic injection molding machine Hydraulic State Road Atlas, is not difficult to find the current domestic injection molding machine used in the electro-hydraulic (magnetic) to the median position of a lot of “O” type, “Y” type, and “N type” , “H” type, “J” type, etc. are rarely used. Have some contact with the domestic injection molding machine who have this experience, that is used in hydraulic parts, electro-hydraulic (magnetic) valve life is shorter, an important reason here is that its work is more frequent, the valve The contact area between the core and the valve body is large, resulting in a large rate of wear. Once the valve body leak increases, the valve loses its function. For a plastic product manufacturer, it is generally incapable of repairing the wear gap
