混凝土输送泵泵送混凝土时,有时发生混凝土缸活塞行至行程端点处不能自动回程,与闸板阀(或摆动管式)动作不协调等故障。为此,对混凝土泵进行故障分析。 从使用维修实践中得知,要找到故障源,需将故障源分解到某个液压系统、液压回路中去;而后进一步分解到部分元件;最后通过这些元件的故障检查,确定故障源。整个混凝土输送泵的故障诊断过程,即是将故障层层分解,使其故障范围逐渐缩小的过程。 Concrete pump delivery of concrete, concrete sometimes occurs at the piston rod to the end of the trip can not automatically return, and the gate valve (or swing tube) action is not coordinated and other failures. To this end, the concrete pump failure analysis. From the use of maintenance practice that, to find the source of the fault, the source of the fault must be decomposed into a hydraulic system, the hydraulic circuit to go; and then further decomposition of some components; Finally, the failure of these components to check to determine the source of the fault. The whole concrete pump fault diagnosis process, that is, fault layers decomposition, so that the scope of the fault gradually narrowing process.
