山东潍坊拖拉机厂XZB148B造型线在调试运转初期经常出现气缸、缓冲缸伸缩不灵导致全线停产的情况,经检查多为二位五通电磁换向阀换向不灵所致。因该阀价格较贵,故备件不多,可换阀多是经过检修、且修完后又无合适的试阀装置检测,故问题较多,换装时往往需要更换多次才能正常工作,大大降低了造型线的运转率。 Weifang tractor factory in Shandong XZB148B modeling line in the early stages of commissioning often appear cylinder, cylinder buffer cylinder ineffective lead to stop production line, after checking for more than two five-way solenoid valve commutation due to not working. Because of the valve price is more expensive, so spare parts is small, the valve can be replaced after many overhaul, and repaired after no test valve device testing, so the problem is more, when the dress often need to be replaced several times to work properly, Greatly reduce the molding line operation rate.
