The pump car is composed of boom, pumping, hydraulic, support and electric control. [1] Concrete pump truck is modified on the chassis of truck, which is installed with motion and power transmission devices, pumping and mixing devices, distributing devices and other auxiliary devices. The power of the concrete pump truck transmits the power of the engine to the hydraulic pump group or the rear axle through the power transfer box, and the hydraulic pump pushes the piston to drive the concrete pump to work. Then the concrete is transported to a certain height and distance using the material rod and conveying pipe on the pump truck.

The electric control system of concrete pump truck mainly has five kinds of mechanical, hydraulic, electromechanical electrical control, programmable controller, logic circuit control. In addition to the electrical control system installed on the concrete pump truck to complete the control task, there is also a manual control system installed, which is also a part of the control system. If mechanical control is used, there are generally rod control mechanism and flexible shaft control mechanism two ways. If the two are compared, it is not difficult to find that the flexible shaft control mechanism has more advantages, such as flexible arrangement, high transmission efficiency, less transition joints and small empty travel, convenient travel adjustment, so the control system of the concrete pump car is mainly to choose the flexible shaft control mechanism

There are two methods of pipe cleaning: wash and air wash. Whether it is washed or air washed, the valve casing and hopper should be cleaned. When washing, put the cement bag and cleaning ball soaked in water into the cleaned cone tube, connect the cone tube and pipe, close the discharge door, and then fill the hopper with water (keep the water source constant). Pump water until the cleaning ball emerges from the front end of the delivery line. Gas washing, namely compressed air blowing, is to plug the water-soaked cleaning ball into the air washing joint first, and then connect the first straight pipe connected with the reducer, and connect the safety cover at the end of the pipe, and the hole of the safety cover should face down. Control the pressure of compressed air is not more than 0.8MPa, the air valve should be slowly opened, when the concrete can be smoothly discharged to open the big air valve.
