Measuring method of concrete pump discharge based on pressure

摘要

The measuring of the real-time discharge of concrete pump is an issue which must be solved urgently. The mathematic model of the concrete pump discharge is established based on the working principle of concrete pump. The measuring method based on pressure is put forward. By measuring and analyzing the pressure in the material cylinder, calculating the real-time pumping efficiency, the real-time discharge of concrete pump could be measured. The preliminary experiment indicates that the measuring method based on pressure has high precision and the measuring error of which is less than 2%.
