Operating system and performance of concrete pump truck:

There are five kinds of control modes in the electric control system of the concrete pump truck, which are mechanical, hydraulic, electrical and mechanical control, programmable logic controller and logic circuit control. In addition to the installation of the electrical control system to complete the control task, the concrete pump truck is also equipped with a manual control system, which is also part of the control system. If the use of mechanical manipulation, there are generally two kinds of control system and the operating mechanism of the flexible shaft.

If the comparison is not difficult to find, flexible operating mechanism has more advantages, such as flexible layout, high transmission efficiency, the transition joint air and less on the trip, travel convenient adjustment, so the control system of the concrete pump truck is the main choice of cable shifting mechanism. According to the actual need, the manipulation of the pump system should be able to achieve stepless speed control, and the joystick can stop at any one location of the locking mechanism is the key to realize the stepless speed regulation control devices, the general can use disc spring or spring plate etc.. For ease of operation, the control handle are designed and installed in more convenient locations, such as Putzmeister BSF36.09Z pump, the engine speed control handle is arranged on the side of the ladder, the operation is very convenient.

The control system of the concrete pump truck is mainly used to control the flow rate of the main hydraulic pump and the engine speed. Such as the use of hydraulic control, you can directly from the pump truck pumping system to obtain hydraulic driving force, and through the manual hydraulic valve control. There is a close relationship with the performance of concrete, and pay attention to the details of operating procedures in the process of operation, timely detection and troubleshooting in order to improve the efficiency of the pump. There are two ways to clean pipes. Whether it is water or gas washing, the valve box and hopper cleaning. When washing, the water soaked into the cement bag and cleaning ball cylindrical has put into clean the cone tube, the cone tube, pipe, close the discharge gate, and then to the hopper is filled with water (water must be kept constant). Pump water until the ball is washed out from the front end of the pipe. The utility model is characterized in that the water soaked cleaning ball is firstly inserted into the air inlet washing joint, and then the first straight pipe is connected with the variable diameter pipe, and a safety cover is connected at the end of the pipeline. Control the pressure of compressed air is not more than 0.8MPa, the valve should be opened slowly, when the concrete can be successfully discharged before the opening of the air valve.
