The hydraulic pump is an indispensable part of the automatic mixer, but after a long time of use, the hydraulic pump will inevitably fail. Which aspects can we start to check?

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 method: smell whether the hydraulic oil has peculiar smell by nose. If the smell of the local burnt smell of the hydraulic oil, it indicates that the hydraulic components such as the hydraulic pump are heated locally, which leads to the coking and smoking of the hydraulic oil, so as to determine the heating position. Smell whether the hydraulic oil has odor or pungent pungent smell. If so, it indicates that the hydraulic oil has been seriously polluted and can not 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 whether the oil quantity is sufficient. Observe whether there is oil leakage at the hydraulic valve and pipeline joint, the end cover of hydraulic cylinder and the transmission shaft of hydraulic pump. Observe the products processed from the equipment or the performance test, identify the working state of the moving 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 is to use 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, whether there is abnormal sound of relief valve and other components, whether the impact sound is too loud when the worktable is reversing, and whether the piston collides with the bottom of hydraulic cylinder, etc.

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 it is higher than 60 ℃, the reason should be found out. Touch the moving parts and oil pipes by hand to feel whether there is obvious vibration.
