Project Description

For the high-altitude,high-concentration,and high-drop working conditions at the Yalong River Mine,FENY independently developed the HGBZ70.15.320G cone valve industrial pump.Through the use of large-diameter sliding valve parallel synchronous control and high-flow,high-back-pressure hydraulic buffering technology,and by configuring a  large-capacity energy storage tank in the discharge pipeline to mitigate the backflow pressure,the pump addresses issues such as high-impact hydraulic system switching and water hammer effects.This is a pioneering case in China,capable of pumping to a height exceeding 500 meters,with a filling system capacity of 60–80 m³/h.

Project Outcome

the highest vertical difference for paste delivery. the First Prize of Scientific and Technological Progress in China's Nonferrous Metals Industry in 2023.
