Prolong service life of fine concrete pump truck and make pump life longer.
Extension Fine aggregate concrete pump The service life of the vehicle and the service life of the pump car are longer. Today, Xiaobian will let you know how to use the pump truck reasonably.
Pump truck vulnerable parts replacement
The wearing parts that need to be replaced are: conveying pipe, glass plate, cutting ring, rubber spring, accumulative sealing body (piston), guide ring, dustproof ring, S shape tube, wear resistant sleeve, YX seal, nylon bearing, mixing shaft socket and seal, size bearing block and seal, delivery cylinder, transition sleeve.
Main cylinder piston rod seal, hydraulic oil, engine oil, transfer box oil, filter element, etc.
Consumption parts should follow the principle of dismantling and replacement: from outside to inside, the first is easy, the top is downward, the left and right are care, the principle is inference, the order is marked, the paper is firmly sealed, security is put in the first place, prevention is the main, and coordination is strictly prohibited.
The following principles should be followed when assembling. First, remove the rear part from inside to outside, then remove one piece. It is difficult, easy to connect, reliable, clean, repeated check and confirm.
Tool selection: try using pneumatic tools, socket wrenches, Plum wrenches, open wrenches and six angle wrenches to reduce labor, save time and protect standard connectors for reuse.
After determining the hydraulic system of the concrete pump truck, the corresponding electrical control system solution can be determined. Mechanical, hydraulic, electromechanical control, programmable logic controller and logic circuit control have five main types. Most of them now use PLC type electrical control systems. In addition to completing the electrical control system of the control task, the concrete pump truck is equipped with a manual control system, which is also part of the control system. If mechanical operation is used, the lever operating mechanism and the flexible shaft operating mechanism usually have two modes. If we compare the two, it is easy to see that the flexible shaft operating mechanism has more advantages, such as flexible layout, high transmission efficiency, less transition joints, small air stroke and convenient stroke adjustment. Therefore, the main choice of the control system concrete pump truck is the flexible shaft control mechanism. According to actual needs, stepless speed regulation should be realized in the pump system. The locking mechanism which can stop the joystick at any position is the key device to achieve stepless speed regulation. Usually, dish springs are used. Or spring plate. To facilitate operation, the joystick is designed to be installed in a convenient location, such as Putzmeister BSF36.09Z pump truck. The joystick that controls engine speed is mounted on the side of the ladder to facilitate operation. The operation system of concrete pump truck is mainly used to control the flow rate and engine speed of the main hydraulic pump, thus changing the concrete displacement of the pump truck. If the hydraulic operation is adopted, the hydraulic driving force can be obtained directly from the pumping system of the pump truck and controlled by the manual hydraulic valve. Such systems are produced by CIFA concrete pump cars produced in Italy and concrete pump trucks produced by Korea Daewoo Corporation. The control panel is usually graphic indicator, easy to learn and understand, and can avoid misoperation.
