Design of Mechanical Injection Type Foam Proportional Mixing Unit

The existing foam proportional mixing devices has the defects such as foam liquid cannot be added at any time and the structure is complex.To solve this problem,a mechanical pumping foam proportional mixing unit and its core components hydroturbine were designed.The working principle and design method of the device were described;the relevant experiments were carried out according to the national standards.The results show that the pressure loss and foam mixing ratio in the designed device meet the requirements of national standards.The research results can provide reference for the research of mechanical pumping foam proportional mixing unit.
