自動上料攪拌車是一種特種車輛，并不是所有會開車的司機都會開攪拌車，如果操作不當會引起翻車、液壓泵、馬達、減速機過快磨損甚出現(xiàn)嚴重后果。所以需要了解相關操作的規(guī)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.
攪拌車車內裝有混凝土時，在現(xiàn)場停滯時間不得超過1小時，如超時應立即要求現(xiàn)場負責人給予及時處理。
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，氣溫高時不得超過2小時必須排出，陰雨天氣溫度低時，不得超過2.5小時。
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.
攪拌車在排出混凝土之前，應使攪拌筒在10-12轉/分的轉速下轉動1分鐘，再進行排料。
Before discharging the concrete, the mixer shall rotate the mixing drum at the speed of 10-12 rpm for 1 minute before discharging.
攪拌車出料完畢，應立即用隨車的沖洗系統(tǒng)放水將進料口、出料斗及出料溜槽等部位沖洗干凈，排去粘結在車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，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.
攪拌車運送混凝土時，發(fā)動機轉速在1000-1400轉/分范圍內工作，以使發(fā)動機有大扭距，在運送混凝土過程中，車速不得超過40km/h，以保行車。
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.
攪拌車水箱的水量要經(jīng)常保持裝滿，以備急用，冬季停車后，應將水罐、水管、攪拌筒內的水放凈，并停放在朝陽、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.
攪拌車在冬季應及時安裝保溫套，并使用防凍液對攪拌車加以保護，根據(jù)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、修理攪拌車液壓傳動部分時，應使發(fā)動機熄火，液壓泵在沒有壓力的情況下進行。
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
自動上料攪拌車各潤滑部位，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.
