Do you know the driving device of the charging mixer? Its function is to drive the concrete storage tank to rotate. If the drive device fails, the whole concrete tank will not rotate, which will lead to the scrapping of concrete in the vehicle, and even the whole tank of concrete will condense in the tank, resulting in vehicle scrapping. So we should do a good job in its maintenance.

1、保證液壓油清潔。自上料攪拌車工作環(huán)境惡劣，一定要防止污水泥沙進入液壓系統(tǒng)。液壓油要按使用手冊要求定期更換。一旦檢查時發(fā)現(xiàn)液壓油中混入水或泥沙，就要立即停機清洗液壓系統(tǒng)、更換液壓油。

1. Keep the hydraulic oil clean. Since the working environment of the loading mixer is bad, it is necessary to prevent the dirty cement sand from entering the hydraulic system. The hydraulic oil should be replaced regularly according to the requirements of the manual. Once it is found that the hydraulic oil is mixed with water or sediment, it is necessary to stop the machine immediately to clean the hydraulic system and replace the hydraulic oil.

2、萬向轉(zhuǎn)動部分是故障多發(fā)部位，應(yīng)按時加注潤滑脂，并經(jīng)常檢查磨損情況，及時修理更換。車隊應(yīng)有備用的萬向軸總成，以保證一旦發(fā)生故障能在幾十分鐘內(nèi)恢復(fù)工作。

2. The universal rotating part is a fault prone part, so grease should be added on time, and the wear condition should be checked frequently, and the repair and replacement should be carried out in time. The team should have spare cardan shaft assembly to ensure that it can resume work in dozens of minutes in case of failure.

3、保證液壓油冷卻裝置有效。要定時清理液壓油散熱器，避免散熱器被水泥堵塞，檢查散熱器電動風(fēng)扇運轉(zhuǎn)是否正常，防止液壓油溫度超標。液壓部分只要保證液壓油清潔，一般故障不多；但生產(chǎn)廠家不同，使用壽命則不一樣。

3. Ensure that the hydraulic oil cooling device is effective. The hydraulic oil radiator should be cleaned regularly to prevent the radiator from being blocked by cement, and check whether the electric fan of radiator operates normally to prevent the temperature of hydraulic oil exceeding the standard. As long as the hydraulic oil is clean, there are not many faults in the hydraulic part, but the service life varies with the manufacturer.

以上就是自上料攪拌車驅(qū)動裝置的維護方法，希望大家能夠定期維護，提高工作效率，延長它的壽命。

The above is the maintenance method of the driving device of self feeding mixer. I hope you can maintain it regularly, improve work efficiency and extend its service life.
