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.
嗅覺(jué)：鼻子是否聞到液壓油？如果您擔心液壓油的氣味，則可以將其確定為高溫部件，因為液壓泵等液壓部件被部分加熱并且液壓油會(huì )燃燒和冒煙。檢查液壓油是否有難聞或刺激性氣味。如果液壓油非常臟，則無(wú)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.
視覺(jué)診斷方法：目視檢查液壓系統的運行狀態(tài)，并觀(guān)察液壓系統每個(gè)壓力測量點(diǎn)的壓力值和溫度變化，以檢查油是否清潔以及油量是否充足。觀(guān)察液壓閥和管接頭，液壓缸端蓋以及液壓泵驅動(dòng)軸是否漏油。在設備加工過(guò)程中觀(guān)察產(chǎn)品或進(jìn)行性能測試，以檢查移動(dòng)機構的工作狀況，系統的壓力和流量穩定性以及電磁閥的工作狀況。
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.
聽(tīng)力診斷：人耳確定液壓系統或部件是否正常工作。傾聽(tīng)液壓泵和液壓系統上是否有過(guò)多的噪音，傾聽(tīng)溢流閥和其他零件上的異常聲音，如果沖擊太大，則傾聽(tīng)工作臺，然后對液壓缸底部的活塞進(jìn)行操作。聽(tīng)聲音。
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.
觸覺(jué)診斷方法：觸摸運動(dòng)部件的溫度和工作狀態(tài)，并觸摸液壓泵殼體，油箱外壁和閥體外殼的溫度。室溫約55℃。如果溫度超過(guò)60°C，則需要檢查原因。觸摸運動(dòng)的零件和管道，并感覺(jué)到明顯的振動(dòng)。
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.
這就是每個(gè)人共享它的方式，以檢測自動(dòng)水混合器中的液壓泵故障。如果在攪拌車(chē)的液壓泵運行過(guò)程中出現故障，則可以使用相應的程序進(jìn)行檢測。
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.
