concrete pump from the motor power

A concrete pump motor power outlet is to determine the amount of pressure and concrete mixing machine motor power given in the case of pressure increase will make the delivery was reduced; Conversely, lowering the outlet pressure will cause the throughput increases. In order to ensure concrete pump conveying both a large amount, but also have some outlet pressure and the matching of economic power in the design of concrete pump, mostly using a constant power piston; namely constant power value selected, when the outlet pressure increases, the pump will automatically reduce the output displacement, achieved with a value corresponding power design; If we want to achieve exports of high pressure, but also want the purpose of transporting large. The only way is to increase the motor power. Therefore, in the new national standards, citing concrete pump capacity index concept (in MPa · m3 / h for the unit of measurement); namely concrete pump outlet pressure and concrete block making machine throughput of the hourly real product, the greater the value its ability to index the greater the power of the motor will also be greater, thus achieving large displacement, high-lift purposes. My company in the design, but also uses a high-voltage switching function designed to meet the requirements of different construction, the state in the economy, but also have a greater throughput, or the same motor power, produce a higher outlet pressure .
