    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.
    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.
    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.
    When the water pump is working, the cement mixer is not allowed to run idle, and the continuous use should not exceed 15 minutes.
    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.
    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.
    When inspecting and repairing the hydraulic transmission part of cement mixer, the engine and hydraulic pump should be operated without pressure.
    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.
