目前砂泵种类繁多,为了不使砂浆不从轴颈流出,几乎都有水封装置,均引高压水进入作为水封,各泵房几乎均配有水封泵,耗能较多。其能耗与水量、水压及选用的水封泵型有直接关系。水封水量与砂泵型号、水封间隙大小及压差大小有关。老砂泵耗水耗能量都很大,水封水压压差越大,水封水耗量也越大,能耗也就越多;水压过高及水封泵选型不当,都会使能耗增大。铜山矿选硫砂泵站标高+60米,生产水池水面标高+125米该泵房原有5台4(1)/2PSJ衬
Currently a wide range of sand pump, mortar does not flow out from the journal, almost all have water seal devices, are cited high-pressure water into the water seal, the pump room is almost all equipped with water seal pump, more energy. Its energy consumption and water, water pressure and the selection of water seal pump has a direct relationship. Water seal water pump type and size, size and size of the water seal pressure on the size. Old sand pump water consumption and energy are large, the greater the water pressure seal, water seal water consumption is greater, the more energy consumption; high water pressure and water seal pump improper selection, will make Increased energy consumption. Tongshan mine selected sulfur sand pumping station elevation of +60 meters, the production of water table elevation +125 meters The original pump room 5 4 (1) / 2PSJ lining
