The automatic feeding mixer is a common transport tool for concrete and clay. It should be ensured that there is no mistake during the transportation. The concrete and soil will be mixed in the whole process, so that the quality of concrete and clay can be maintained well until the destination is reached. The operation requirements of its hydraulic rotation system are as follows:

　　1、新車開(kāi)始使用前，檢查和液壓系統(tǒng)各處的灰塵和雜物，并檢查各處連接是否正確和有無(wú)其它問(wèn)題。

　　1. Before the new car starts to use, first check and remove the dust and debris around the hydraulic system, and check whether the connection is correct and whether there are other problems.

　　2、油箱中裝液壓油到油標(biāo)刻度線以上，泵殼和馬達(dá)殼內(nèi)也要充油。

　　2. The oil tank is filled with hydraulic oil above the oil mark, and the pump housing and motor housing should also be filled with oil.

　　3、啟動(dòng)發(fā)動(dòng)機(jī)，操縱伺服手柄使自動(dòng)上料攪拌機(jī)拌筒在低速下正轉(zhuǎn)，觀察液壓系統(tǒng)是否正常工作。

　　3. Start the engine, operate the servo handle to make the mixing drum of automatic feeding mixer rotate forward at low speed, and observe whether the hydraulic system works normally.
                

　　4、油溫不得超過(guò)60℃，泵殼壓力必須小于0.25MPa。

　　4. The oil temperature should not exceed 60 ℃, and the pump shell pressure must be less than 0.25MPa.

　　5、注意散熱器上的風(fēng)扇在50℃-70℃范圍內(nèi)應(yīng)是運(yùn)轉(zhuǎn)狀態(tài)。風(fēng)扇發(fā)生故障不運(yùn)轉(zhuǎn)時(shí)，應(yīng)及時(shí)修理。

　　5. Note that the fan on the radiator should be in operation state within the range of 50 ℃ - 70 ℃. When the fan fails to work, it should be repaired in time.

　　6、補(bǔ)油泵溢流閥、低壓溢流閥、高壓溢流閥壓力出廠時(shí)已調(diào)定，不得隨意改動(dòng)。

　　6. The pressure of relief valve, low-pressure relief valve and high-pressure relief valve of make-up oil pump has been set before delivery and shall not be changed at will.

　　7、自動(dòng)上料攪拌機(jī)油路中各部件及管路不得有漏油現(xiàn)象，如發(fā)生滲漏，應(yīng)及時(shí)修理。

　　7. There shall be no oil leakage in the parts and pipelines of the automatic feeding and mixing oil pipeline. In case of leakage, it shall be repaired in time.

　　8、工作運(yùn)轉(zhuǎn)狀態(tài)時(shí)，不得隨意修理和調(diào)整。

　　8. It is not allowed to repair and adjust at will when working.

　　9、液壓油泵、馬達(dá)若發(fā)生故障需及時(shí)更換下來(lái)送指定維修部修理。

　　9. If the hydraulic oil pump and Mada fail, they should be replaced in time and sent to the professional designated maintenance department for repair.

　　我們?cè)隈{駛自動(dòng)上料攪拌機(jī)的時(shí)候應(yīng)該做好各個(gè)方面的檢查，液壓轉(zhuǎn)動(dòng)系統(tǒng)對(duì)于整個(gè)攪拌車來(lái)說(shuō)是很關(guān)鍵的一部分，液壓轉(zhuǎn)動(dòng)系統(tǒng)符合使用要求才能率使用攪拌車。

　　We should do a good job in all aspects of the inspection when driving the automatic feeding mixer. The hydraulic rotation system is a key part of the whole mixer. Only when the hydraulic rotation system meets the requirements can we use the mixer efficiently.
