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?

嗅覺診斷法：是用鼻子聞液壓油是否有異味，若聞到液壓油局部有焦臭味，說明液壓泵等液壓元件局部發(fā)熱，導(dǎo)致液壓油被烤焦冒煙，據(jù)此可判斷其發(fā)熱部位。聞液壓油是否有惡臭味或刺鼻的辣味，若有說明液壓油已嚴(yán)重污染，不能再繼續(xù)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.

視覺診斷法：是用眼睛來觀察液壓系統(tǒng)工作情況，觀察液壓系統(tǒng)各測壓點(diǎn)的壓力值、溫度變化情況，檢查油液是否清潔、油量是否充足。觀察液壓閥及管路接頭處、液壓缸端蓋處、液壓泵傳動軸處等是否有漏油現(xiàn)象。觀察從設(shè)備加工出的產(chǎn)品或所進(jìn)行的性能試驗(yàn)，鑒別運(yùn)動機(jī)構(gòu)的工作狀態(tài)、系統(tǒng)壓力和流量的穩(wěn)定性以及電磁閥的工作狀態(tài)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.

聽覺診斷法：是用耳朵來判斷液壓系統(tǒng)或元件的工作是否正常等。聽液壓泵和液壓系統(tǒng)噪聲是否過大;聽溢流閥等元件是否有異常聲音;聽工作臺換向時沖擊聲是否過大;聽活塞是否有沖撞液壓缸底的聲音等。

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.

自動攪拌車

Automatic mixer

觸覺診斷法：是用手觸摸運(yùn)動部件的溫度和工作狀態(tài)，用手觸摸液壓泵外殼、油箱外壁和閥體外殼的溫度。正常溫度應(yīng)在55℃左右，如果超過60℃以上就應(yīng)檢明原因。用手觸摸運(yùn)動部件和油管，感覺有無明顯振動。

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.
