Concrete pump trapped with constant power regulation

It is a measure of the ability of a concrete pumping integrated indicators, but also concrete pump main basis for classification.
① same power different concrete pump, its pumping capacity index identical; ② in concrete pumping pressure is constant, the amount of concrete surface increases with the increase of power; ③ In the dynamic power is fixed, with the pressure pumping concrete increases, the amount of concrete mixing machine, and vice versa.Concrete Mixing Truck trapped with constant power regulation, so concrete pump working pressure of the outlet end of pumping concrete and concrete product of the actual maximum throughput is a certain value, this value is called the pumping capacity index, denoted by M.
