        混凝土输送泵换向系统的两大常见故障及解决方

            混凝土输送泵在使用的过程中,换向系统如果出现问题如何解决呢?下面我们为大家介绍一下混凝土输送泵换向系统的两大常见故障及解决方法:

        1、主油缸不换向 

        故障原因:缺少液压油,熔断器烧断,反向按钮接触不良,反向继电器插座接线松动,电气控制箱内延迟继电器损坏,发光二极管不闪亮,发光二极管永久性闪亮,液压换向阀阀芯因脏物粘滞,电磁换向阀线圈烧断。 

        解决方法:加注液压油到规定位置,更换熔断器,检修或更换反向按钮,消除接线松动,更换延迟继电器,更换发光二极管,将开关插紧,清除换向阀阀芯中的脏物,使阀芯能自由移动,检修或更换电磁换向阀。 

        2、分配阀不能自动换向 

        故障原因:蓄能器油路不充压,分配阀反向开关损坏或接触不良,S管摆动区域内聚积了骨料或骨料沉积于料斗内,阻碍换向。 

        解决方法:检查蓄能器压力,关闭蓄能器卸荷阀,检修或更换反向开关,采用反复换向和反向泵送的方法将S管区域内的骨料泵送出去,必要时可打开料斗的卸料口清除骨料沉积物。所泵送的砼应满足可泵送性要求。

            以上就是混凝土输送泵换向系统的两大故障及解决方法,希望对大家有所帮助。
