The working principle for the injection of liquid out of well-head pipe back into the first two cyclone Desander will remove large particles of sediment; and then entered magnetic processor, remove the suspended solids containing magnetic iron, and then enter the inclined plate oil remover, the removal of the majority of the oil particles; then into walnut shell filter to remove most of them and the oil and suspended solids; and finally the ball into the fiber filters, which remove smaller oil and suspended solids; treated water into the fresh water tank, water tank in the filtered water to Cyprus by a triplex injection pump delivery into the injection wells wellhead casing to form a loop flushing operation.
其工作原理为注水井口油管返出的液体首先进入两级旋流除砂器，将大颗粒的泥沙除去；随后进入磁处理器，除去含有铁磁性的悬浮物，然后进入斜板除油器，去除其中的大部分油粒；然后进入核桃壳过滤器，除去其中的大部分和油及悬浮物；最后进入纤维球过滤器，除去其中更小的油及悬浮物；处理后的水进入清水箱，水箱中的滤后水再由三缸注塞泵输送进入注水井井口套管，形成循环洗井作业。
The pressure of pressure stabilizing pump will be settled on the basis of its delivery head which is not calculated but determined by the delivery head of main fire pump as the function of it is to stabilize the pressure inside the fire water system.
提要 稳压泵的压力设定值决定于稳压泵扬程，稳压泵的扬程一般不另行计算，而是采用消防主泵的扬程，其原因在于设置稳压泵的目的是使消防给水管网的水压稳定。
