辽宁省保国铁矿选矿厂原32米。内滤式过滤机采用8Z-4型水环式真空泵作真空设备。自采用山东博山阀门厂生产的SPB-600型水喷射泵取代水环式真空泵之后,取得了良好的应用效果:铁精矿水份由11.5％下降为10％;铁精矿滤饼厚度由15～20毫米上升为18～23毫米;电耗由每小时54.7度下
Liaoning Province Baoguo iron ore beneficiation plant 32 meters. Internal filter filter using 8Z-4 water ring vacuum pump for vacuum equipment. Since the adoption of SPB-600 water jet pump manufactured by Shandong Boshan Valve Factory, the water ring vacuum pump has been replaced with good application effect: the water content of iron concentrate has dropped from 11.5% to 10%; the thickness of the iron concentrate cake has increased from 15 ~ 20 mm rose to 18 ~ 23 mm; power consumption by 54.7 degrees per hour
