Concrete used large displacement pump

Generally used in the pump pressure of the concrete 9 ~ 13MPa, large displacement of the pump up to 15 ~ 22MPa, pushing the piston hydraulic system pressure is generally rated pressure of 1/3. Concrete mixer delivery pressure pushes the piston depends on the ability and the total resistance of the pipeline, the two also determines the size of the pump conveying distance. Ability to push the piston structure itself is determined by the prime mover. General model to determine the pump size can not be changed later. Determined by the total resistance of the pipeline has a lot of factors, such as concrete gradation has been described previously. Under normal concrete mixing machine,  the most influential design of piping, such as the transmission distance of the horizontal or vertical, the number of straight pipe, elbow, conical tubes and hoses. So be careful in the construction designs are arranged.
