hydraulic valve opening

The machine has the drawbacks of short service life,as well as big difficulties and high cost in maintenance,In view of the above drawbacks,a pure hydraulic nozzle-tapping machine was utilized for the 1# 1750 blast furnace,which was modified and optimized,and taken as the experiment site.

针对以上缺陷,将1号1750高炉作为试点,通过一系列优化改造,在不停产的情况下将气动开口机改为液压开口机,取得了良好的效果。

A computer intelligent control system, which consists of microcomputer, switch mode hydraulic valve and displacement sensor, is developed.

研制出了由微机、开关式液压阀及位移传感器等组成的液压送进装置的计算机智能控制系统。
