When using the hydraulic pump of the mixer, the failure of the hydraulic system will greatly reduce the performance of the mixer. It is suggested to understand the causes of the hydraulic system failure of the mixer, eliminate and maintain the fault, so that the mixer can resume normal operation without affecting the working time. Let's look at how to detect a hydraulic pump fault in the automatic feed mixer.
嗅觉：鼻子是否闻到液压油？如果您担心液压油的气味，则可以将其确定为高温部件，因为液压泵等液压部件被部分加热并且液压油会燃烧和冒烟。检查液压油是否有难闻或刺激性气味。如果液压油非常脏，则无法使用。
Smell: does nose smell hydraulic oil? If you are worried about the smell of the hydraulic oil, you can identify it as a high temperature component, because the hydraulic components such as the hydraulic pump are partially heated and the hydraulic oil will burn and smoke. Check the hydraulic oil for unpleasant or irritating odor. If the hydraulic oil is very dirty, it cannot be used.
视觉诊断方法：目视检查液压系统的运行状态，并观察液压系统每个压力测量点的压力值和温度变化，以检查油是否清洁以及油量是否充足。观察液压阀和管接头，液压缸端盖以及液压泵驱动轴是否漏油。在设备加工过程中观察产品或进行性能测试，以检查移动机构的工作状况，系统的压力和流量稳定性以及电磁阀的工作状况。
Visual diagnosis method: visual inspection of the operation status of the hydraulic system, and observe the pressure value and temperature change of each pressure measuring point of the hydraulic system to check whether the oil is clean and whether the oil quantity is sufficient. Observe the hydraulic valve and pipe joint, hydraulic cylinder end cover and hydraulic pump drive shaft for oil leakage. In the process of equipment processing, observe the product or conduct performance test to check the working condition of mobile mechanism, the stability of system pressure and flow and the working condition of solenoid valve.
听力诊断：人耳确定液压系统或部件是否正常工作。倾听液压泵和液压系统上是否有过多的噪音，倾听溢流阀和其他零件上的异常声音，如果冲击太大，则倾听工作台，然后对液压缸底部的活塞进行操作。听声音。
Hearing diagnosis: the ear determines whether the hydraulic system or component is working properly. Listen to the hydraulic pump and hydraulic system for excessive noise, listen to the abnormal sound on the relief valve and other parts, if the impact is too big, listen to the workbench, and then operate the piston at the bottom of the hydraulic cylinder. Listen to the sound.
触觉诊断方法：触摸运动部件的温度和工作状态，并触摸液压泵壳体，油箱外壁和阀体外壳的温度。室温约55℃。如果温度超过60°C，则需要检查原因。触摸运动的零件和管道，并感觉到明显的振动。
Tactile diagnosis method: touch the temperature and working state of moving parts, and touch the temperature of hydraulic pump housing, oil tank outer wall and valve body shell. The room temperature is about 55 ℃. If the temperature exceeds 60 ° C, the cause needs to be checked. Touch moving parts and pipes and feel obvious vibration.
这就是每个人共享它的方式，以检测自动水混合器中的液压泵故障。如果在搅拌车的液压泵运行过程中出现故障，则可以使用相应的程序进行检测。
This is how everyone shares it to detect a hydraulic pump fault in the automatic water mixer. If there is a fault in the operation of the hydraulic pump of the mixer truck, the corresponding program can be used for detection.
