Cement mixer is a very common engineering vehicle, so how much do you know about hydraulic conveying? After the discharge of cement mixer, immediately flush the inlet, outlet hopper and discharge chute with the hose attached to the truck, remove the dirt and residual concrete adhered to the body, and then inject 150-200l clean water into the mixing drum. On the way back, let the mixing drum rotate slowly to clean the inner wall, so as to avoid the residual slag adhering to the wall and mixing blade, And discharge the water before loading again.

水泥攪拌車運送混凝土水泥的時候，發(fā)動機轉速在1000-1400轉/分范圍內工作，以使發(fā)動機有扭距，在運送水泥過程中，車速不得超過40km/h，以保行車。

When transporting concrete, the engine speed of cement mixer should be in the range of 1000-1400 rpm to make the engine have the maximum torque. In the process of transporting cement, the speed should not exceed 40km / h to ensure driving safety.

水泥攪拌車工作完畢，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 cement mixer is completed, the inside and body of the mixing drum shall be cleaned, and the remaining concrete shall not be left in the drum.

水泥攪拌車在水泵工作時，禁止空轉，連續(xù)使用時不要超過15分鐘。

When the water pump is working, the cement mixer is not allowed to run idle, and the continuous use should not exceed 15 minutes.

水泥攪拌車水箱的水量要經常保持裝滿，以備急用，冬季停機后，應將水箱、水泵、水管、攪拌筒內的水放凈，并停放在朝陽、不積水的地方，以免凍壞機械。

The water in the water tank of the cement mixer should always be kept full for emergency use. After stopping in winter, the water in the water tank, water pump, water pipe and mixing drum should be drained, and the water should be parked in the sunny place without ponding, so as to avoid freezing the machinery.

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 should be installed with insulation sleeve in time, and use antifreeze to protect the mixer. The fuel label should be changed according to the weather change to ensure the normal use of the machinery.

在檢查、修理水泥攪拌車液壓傳動部分時，應使發(fā)動機和液壓泵在沒有壓力的情況下進行。

When inspecting and repairing the hydraulic transmission part of cement mixer, the engine and hydraulic pump should be operated without pressure.

在調整水泥攪拌車各部間隙、行程、壓力時，應由專職員檢查同意;更換機件時，必須由部長或主管經理簽字，否則出現(xiàn)問題后追究有關人員責任。

When adjusting the clearance, travel and pressure of each part of the cement mixer, it should be checked and agreed by the full-time safety officer; When replacing the machine parts, it must be signed by the minister or the manager in charge, otherwise the relevant personnel will be held responsible after the problems occur.
