Concrete Pump Elbow The use of pressure to transport the concrete along the pipeline. By the pump and the composition of the pipeline. According to the structure is divided into piston type, squeeze type, water pressure diaphragm type. The pump body installed in the car chassis, and then equipped with retractable or inflected cloth rod, the composition of the pump. The concrete pump is retrofitted on a truck chassis, which is equipped with a sports and powertrain, a pump and a stirrer, a cloth, and other auxiliary devices on the chassis. The power of the concrete pump through the power transfer box to the engine power transmission to the hydraulic pump or rear axle, hydraulic pump to promote the piston to drive the concrete pump work. And then use the pump on the cloth rod and the delivery pipe, the concrete will be transported to a certain height and distance.
Concrete Pump Elbow Concrete pump electric control system control methods are mainly five kinds of mechanical, hydraulic, electromechanical control, programmable logic controller, logic circuit control. In addition to the installation of electrical control system to complete the control task, the concrete pump is equipped with a manual control system, which is also part of the control system. If the use of mechanical manipulation, the general control of the rod and the shaft control mechanism in two ways. If the comparison between the two is not difficult to find, flexible shaft control mechanism has more advantages, such as flexible layout, high transmission efficiency, less transition joints and small empty stroke, easy travel adjustment, so the concrete pump truck operating system Mainly to choose the flexible shaft control mechanism. According to actual needs, in the pump operating system should be able to achieve stepless speed control, and can make the joystick to stop at any one position of the locking mechanism is to achieve stepless speed control of the key device, generally can choose disc spring Or spring board. For ease of operation, the joystick is designed to be installed in a more convenient location, such as the Putzmeister BSF36.09Z pump, the control of the engine speed control handle installed in the ladder side, the operation is very convenient. The concrete pump truck's operating system is mainly used to control the main hydraulic pump flow and engine speed, thereby changing the pump discharge of concrete. Such as the use of hydraulic control, you can directly from the pump pumping system to obtain hydraulic drive force, and through the manual hydraulic valve to achieve control. And the performance of concrete are inseparable relationship, while the operation process attention to the details of the operating procedures, timely detection and troubleshooting in order to improve the efficiency of the pump. Pipeline cleaning There are two ways to wash and air wash. Whether it is washed or air washing, the valve box and hopper should be cleaned. When the water is washed, the cemented bag and the cleaning ball which have been dipped in water have been put into a clean cone tube, connected to a tapered pipe, a pipe, close the discharge door, and then fill the hopper with water Continuous water). Pump the water until the cleaning balls emerge from the front end of the pipe. Air wash that is compressed air purge, is the soaked water cleaning ball first into the airtight connection, and then connected with the reducer connected to the first straight pipe, and in the end of the pipe connected to the safety cover, safety cover The orifice is going down. Control the pressure of compressed air does not exceed 0.8MPa, the valve should be slow to open, when the concrete can flow out of the open air valve.
Concrete Pump Elbow Maintenance
1, the concrete pump truck maintenance methods should be in accordance with the maintenance manual in the corresponding requirements and methods, daily use, before and after the use of pump-related projects to check.
2, in accordance with the use of maintenance manual in the corresponding requirements and methods, refer to the lubrication table, the pump parts for timely and adequate lubrication.
3, in accordance with the use of maintenance manual in the corresponding requirements and methods, select the designated model of hydraulic oil, regular replacement of hydraulic system oil.
4, in accordance with the manual in the concrete pump truck maintenance methods and requirements, regular inspection pump part of the water tank, concrete tank, concrete pipe.
