Operating system and the performance of concrete pump truck

Control concrete pump electrical control system there are five main mechanical, hydraulic, electromechanical electrical control type, the programmable controller type, logic-controlled. In addition to the concrete truck pump control system to complete the installation of electrical control tasks, is also equipped with a manual control to manipulate the system, it is also part of the system of control. 

If mechanical manipulation, generally bar system controls and flexible shaft steering mechanism in two ways. If you compare the two is not difficult to find, flexible shaft control mechanism have more advantages, such as layout flexibility, high transmission efficiency, transition joints and small air travel less convenient travel adjustment, etc., so theconcrete pump control system The main shaft is to select the operating mechanism. According to actual needs, in truck’s operating system should be able to achieve variable speed operation, while enabling the joystick to stop at any position locking mechanism is a key means to achieve stepless operated, generally you can use the disc springs or spring board. For ease of operation, joystick are designed to be installed at a convenient location, such as Putzmeister BSF36.09Z type pump, which controls the engine speed joystick mounted on the side of the ladder, the operation is very convenient. Concrete pump control system is mainly used to control the main pump flow and engine speed, thereby changing the concrete pump discharge amount. Such as the use of hydraulic control, it can get power directly from the hydraulic drive pump pumping systems, and to achieve through manual hydraulic control valve. There is a close relationship with the properties of concrete, while paying attention to detail procedures in the course of operation, the timely detection and timely troubleshooting to improve pump efficiency. There are two methods to clean water pipes and gas wash. Whether it is water or air wash, should the valve housing and hopper clean. When washing, the water soaked tied cylindrical cement bags and cleaning ball has been put into clean cone tube, connected to the cone, pipe, close the discharge door, hopper filled with water again (to be kept Water constantly). Pumping water until cleaning ball out from the tip of the delivery tube so far. Gas wash or compressed air purging, is the first water-soaked cleaning ball into the air purge fitting, connect with the adjustable tube connecting the first root straight, and at the end of the pipe connected to the safety cover, safety cover opening to down. Control air pressure does not exceed 0.8MPa, slowly open the valve, when the concrete can flow smoothly before opening a large valve.
