In the process of using the hydraulic pump of the mixer, if the hydraulic system fails, the working performance of the mixer will be greatly reduced. Should be very good to understand the cause of the mixer hydraulic system failure, can be very good troubleshooting and maintenance, can let the mixer return to normal work, does not affect the work schedule. Now let's take a look at the detection of automatic feeding mixer hydraulic pump fault method.

嗅觉诊断法：是用鼻子闻液压油是否有异味，若闻到液压油局部有焦臭味，说明液压泵等液压元件局部发热，导致液压油被烤焦冒烟，据此可判断其发热部位。闻液压油是否有恶臭味或刺鼻的辣味，若有说明液压油已严重污染，不能再继续使用。

Olfactory diagnosis: use nose to smell whether the hydraulic oil has peculiar smell. If you smell the local burnt smell of the hydraulic oil, it means that the hydraulic components such as the hydraulic pump are locally heated, causing the hydraulic oil to be scorched and smoke. According to this, you can judge the hot part. Smell whether the hydraulic oil has stench or pungent pungent smell. If so, it indicates that the hydraulic oil has been seriously polluted and cannot be used any more.
          

视觉诊断法：是用眼睛来观察液压系统工作情况，观察液压系统各测压点的压力值、温度变化情况，检查油液是否清洁、油量是否充足。观察液压阀及管路接头处、液压缸端盖处、液压泵传动轴处等是否有漏油现象。观察从设备加工出的产品或所进行的性能试验，鉴别运动机构的工作状态、系统压力和流量的稳定性以及电磁阀的工作状态等。

Visual diagnosis method: use eyes to observe the working condition of the hydraulic system, observe the pressure value and temperature change of each pressure measuring point of the hydraulic system, and check whether the oil is clean and sufficient. Observe whether there is oil leakage at the joint of hydraulic valve and pipeline, end cover of hydraulic cylinder and transmission shaft of hydraulic pump. Observe the products processed from the equipment or the performance test, identify the working state of the motion mechanism, the stability of the system pressure and flow, and the working state of the solenoid valve.

听觉诊断法：是用耳朵来判断液压系统或元件的工作是否正常等。听液压泵和液压系统噪声是否过大;听溢流阀等元件是否有异常声音;听工作台换向时冲击声是否过大;听活塞是否有冲撞液压缸底的声音等。

Auditory diagnosis: it uses the ear to judge whether the hydraulic system or components work normally. Listen to whether the noise of hydraulic pump and hydraulic system is too loud; listen to whether the relief valve and other components have abnormal sound; listen to whether the impact sound of worktable reversing is too loud; listen to whether the piston collides with the bottom of hydraulic cylinder.

触觉诊断法：是用手触摸运动部件的温度和工作状态，用手触摸液压泵外壳、油箱外壁和阀体外壳的温度。正常温度应在55℃左右，如果超过60℃以上就应检明原因。用手触摸运动部件和油管，感觉有无明显振动。

Tactile diagnosis method: touch the temperature and working state of moving parts by hand, and touch the temperature of hydraulic pump shell, oil tank outer wall and valve body shell by hand. The normal temperature should be about 55 ℃. If the temperature exceeds 60 ℃, the cause should be found out. Touch the moving parts and oil pipes with hands to feel whether there is obvious vibration.

以上给大家分享的是检测自动上料搅拌车液压泵故障的方法，大家在操作搅拌车液压泵过程中，如果出现故障，可以采取以上方案对应的去检测。

The above is to share with you the method of detecting the fault of the hydraulic pump of the automatic feeding mixer. If there is a fault in the process of operating the hydraulic pump of the mixer, you can take the corresponding detection of the above scheme.
