在卡盘滑阀式混凝土泵(占我国目前使用的混凝土输送泵约50％以上)的使用过程中,有一些和混凝土直接接触的部件,如滑阀,滑阀底罩、搅拌叶片、输送缸、输送管等,它们的磨损量相对于一般部件要大得多。当这些部件磨损到一定程度,就会对混凝土输送产生不利影响,如输送效率低、混凝土离析、堵管等。解决的办法是更换磨损过度的部件,除搅拌叶片较便宜外,其它部件的价格都较贵,如果采用正确的堆焊修复,一般均可达到修复的目的。

In the process of using the chute type concrete pump (accounting for more than 50% of the concrete pump currently used in our country), there are some components that are in direct contact with the concrete, such as the slide valve, the slide valve bottom cover, the stirring blade, , Pipes, etc., their wear relative to the general components is much larger. When these parts wear to a certain extent, it will adversely affect the delivery of concrete, such as low transmission efficiency, concrete segregation, plugging and so on. The solution is to replace the excessive wear parts, in addition to cheaper mixing blades, the other parts are more expensive, if the correct surfacing repair, generally can achieve the purpose of repair.
