When using the hydraulic pump of a small mixer, the failure of the hydraulic system will greatly reduce the performance of the mixer. It is suggested to understand the cause of the mixer hydraulic system failure, so as to solve and maintain it, so that the mixer can return to normal operation without affecting the normal operation time. Let's see how to detect the hydraulic pump failure of the automatic feeding mixer.
 

 

气味诊断：您是否闻到鼻子中的液压油？如果液压油有异味，则液压泵等液压零件会被部分加热，并且液压油会燃烧并散发烟气，因此您可以判断是否是高温零件。检查液压油是否有难闻或刺鼻的气味。如果液压油被严重污染，则不能使用它。

Odor diagnosis: do you smell the hydraulic oil in your nose? If the hydraulic oil has a peculiar smell, the hydraulic parts such as the hydraulic pump will be partially heated, and the hydraulic oil will burn and emit smoke, so you can judge whether it is a high temperature part. Check the hydraulic oil for bad or pungent smell. If the hydraulic oil is seriously contaminated, it cannot be used.

视觉诊断方法：目视观察液压系统的运行状况，观察液压系统每个压力测量点的压力值和温度变化，并确认油是否清洁且油量是否充足。观察液压阀和管路之间的接头，液压缸的端盖以及液压泵的驱动轴是否漏油。观察设备处理过的产品或进行性能测试，以确定移动机构的运行状态，系统压力和流量的稳定性以及电磁阀的运行状态。

Visual diagnosis method: visually observe the operation of the hydraulic system, observe the pressure value and temperature change of each pressure measuring point of the hydraulic system, and confirm whether the oil is clean and sufficient. Observe the joint between the hydraulic valve and the pipeline, the end cover of the hydraulic cylinder and the drive shaft of the hydraulic pump for oil leakage. Observe the products processed by the equipment or conduct performance test to determine the operation status of the mobile mechanism, the stability of the system pressure and flow, and the operation status of the solenoid valve.

听觉：人耳决定液压系统或组件是否正常运行。听听液压泵和液压系统的过多噪音。聆听溢流阀和其他组件的异常噪音。如果影响太大，请收听工作台。听听液压缸底部的活塞声音。

Hearing: the human ear determines whether the hydraulic system or components work properly. Listen to the excessive noise of the hydraulic pump and hydraulic system. Listen for abnormal noise from relief valve and other components. If the impact is too big, listen to the workbench. Listen to the piston at the bottom of the cylinder.

触觉诊断方法：触摸运动部件的温度和工作条件，并触摸液压泵壳体，油箱外壁和阀体壳体的温度。室温约为55℃。如果温度超过60°C，则需要确定原因。触摸运动部件和管道，感觉明显的振动。

Tactile diagnosis method: touch the temperature and working conditions of moving parts, and touch the temperature of hydraulic pump shell, 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 determined. Touch moving parts and pipes to feel obvious vibration.

以上是用于检测小型搅拌机的液压泵中的故障的共享方法。如果在搅拌机的液压泵运行过程中发生故障，则可以使用相应的程序进行检测。

The above is a shared method for detecting faults in the hydraulic pump of a small mixer. If the hydraulic pump of the mixer fails during operation, the corresponding program can be used for detection.
