自動(dòng)上料攪拌車(chē)是一種特種車(chē)輛，并不是所有會(huì )開(kāi)車(chē)的司機都會(huì )開(kāi)攪拌車(chē)，如果操作不當會(huì )引起翻車(chē)、液壓泵、馬達、減速機過(guò)快磨損甚出現嚴重后果。所以需要了解相關(guān)操作的規范是怎樣的。

The automatic loading mixer truck is a special vehicle, and not all drivers who can drive it will drive it. If it is not operated properly, it will cause overturning, rapid wear of hydraulic pump, motor and reducer, and even serious consequences. Therefore, we need to understand the specifications of relevant operations.

攪拌車(chē)車(chē)內裝有混凝土時(shí)，在現場(chǎng)停滯時(shí)間不得超過(guò)1小時(shí)，如超時(shí)應立即要求現場(chǎng)負責人給予及時(shí)處理。

When the mixer truck is loaded with concrete, the standstill time on the site shall not exceed 1 hour. If it exceeds the time limit, the person in charge of the site shall be immediately required to deal with it in a timely manner.

攪拌車(chē)運送混凝土塌落度不得低于5cm。從混凝土入罐到排出，氣溫高時(shí)不得超過(guò)2小時(shí)必須排出，陰雨天氣溫度低時(shí)，不得超過(guò)2.5小時(shí)。

The slump of concrete transported by mixer truck shall not be less than 5cm. From the time of concrete pouring into the tank to discharging, it must be discharged within 2 hours when the temperature is high, and within 2.5 hours when the temperature is low in rainy weather.

攪拌車(chē)在排出混凝土之前，應使攪拌筒在10-12轉/分的轉速下轉動(dòng)1分鐘，再進(jìn)行排料。

Before discharging the concrete, the mixer shall rotate the mixing drum at the speed of 10-12 rpm for 1 minute before discharging.

攪拌車(chē)出料完畢，應立即用隨車(chē)的沖洗系統放水將進(jìn)料口、出料斗及出料溜槽等部位沖洗干凈，排去粘結在車(chē)身各處的污物及殘留混凝土，再向攪拌筒內注水150-200L的清水，在返回途中要讓攪拌筒慢速轉動(dòng)，以清洗內壁，避免殘余料渣附在筒壁和攪拌葉上，并在再一次裝料前將這些水放掉。

After the discharge of the mixer truck, the feeding inlet, discharge hopper, discharge chute and other parts should be washed with water immediately with the flushing system of the truck, the dirt and residual concrete adhered to the body should be discharged, and then 150-200l of clean water should be injected into the mixing drum. On the way back, the mixing drum should be turned slowly to clean the inner wall, so as to avoid the residual slag attached to the drum wall and mixing blade, and these water should be discharged before loading again.

攪拌車(chē)運送混凝土時(shí)，發(fā)動(dòng)機轉速在1000-1400轉/分范圍內工作，以使發(fā)動(dòng)機有大扭距，在運送混凝土過(guò)程中，車(chē)速不得超過(guò)40km/h，以保行車(chē)。

When the mixer truck is transporting concrete, the engine speed is within the range of 1000-1400 rpm, so that the engine has a large torque. In the process of transporting concrete, the speed should not exceed 40km / h, so as to ensure driving safety.

工作完畢，應把攪拌筒內部和車(chē)身清洗干凈，不能使剩余的混凝土留在筒內。

After the work is completed, the interior of the mixing drum and the vehicle body shall be cleaned, and the remaining concrete shall not be left in the drum.

攪拌車(chē)水箱的水量要經(jīng)常保持裝滿(mǎn)，以備急用，冬季停車(chē)后，應將水罐、水管、攪拌筒內的水放凈，并停放在朝陽(yáng)、不積水的地方，以免凍壞部件及管路。

The water tank of the mixer truck should always be kept full for emergency use. After parking in winter, drain the water in the water tank, water pipe and mixing drum, and park it in a sunny place without ponding, so as to avoid freezing and damaging the parts and pipelines.

攪拌車(chē)在冬季應及時(shí)安裝保溫套，并使用防凍液對攪拌車(chē)加以保護，根據天氣變化更換燃油標號，確保機械的正常使用。

In winter, the mixer truck should be installed with insulation sleeve in time, and use antifreeze to protect the mixer truck. The fuel grade should be changed according to the weather changes to ensure the normal use of the machinery.

在檢查、修理攪拌車(chē)液壓傳動(dòng)部分時(shí)，應使發(fā)動(dòng)機熄火，液壓泵在沒(méi)有壓力的情況下進(jìn)行。

When checking and repairing the hydraulic transmission part of the mixer truck, the engine should be shut down and the hydraulic pump should be operated without pressure.

經(jīng)常性檢查自動(dòng)上料攪拌車(chē)各潤滑部位，尤其是托輪，要經(jīng)常性的注入潤滑脂。

Regularly check the lubricating parts of the automatic feeding mixer, especially the supporting wheel, and inject lubricating grease regularly.
