How to choose a concrete pump

A concrete pump has the following main technical parameters: delivery displacement, outlet pressure, motor power and distribution valve form. According to the new national standards, these main parameters are known from the model of the concrete pump. 

The motor power of a concrete pump is the precondition for determining the outlet pressure and the delivery volume. When the motor power is constant, the increased pressure will reduce the delivery volume; on the contrary, reducing the outlet pressure will increase the delivery volume. In order to ensure that the concrete pump has a large conveying capacity, and can have a certain outlet pressure with the matching economic power, in the design of the concrete pump, most of the constant power piston pump is used; that is, the constant power value After the selection, when the outlet pressure rises, the output displacement of the oil pump will automatically decrease, reaching the value corresponding to the power design; if it is necessary to achieve high outlet pressure, and customer want to obtain a large amount of transportation.



The only way is to increase the motor power. Therefore, in the new national standard, the concept of capacity index of concrete pump (measured in MPa•m3/h) is quoted; Which is the product of the actual outlet pressure of the concrete pump and the actual delivery volume per hour. The higher the capacity index, the higher the power of the motor, thus achieving the goal of large displacement and high lift.
