    • A submersible pump for attachment to the lower end of a well pipe discharge tube for insertion in liquid includes a stationary collecting tube for collecting the liquid and an upward and downward reciprocating pumping tube within the collecting tube for pushing and lifting the liquid into the discharge tube; source of pressurized gas, a casing assembly including a casing tube and a gas valve, and a piston assembly with the casing tube including a piston tube having a lower end connected to the pumping tube for reciprocating the pumping tube and an upper portion having pistons for moving in chambers with the inside of the casing tube. Preferably the same amount of liquid is pumped during the upward movement of the pumping tube as during the downward movement.
    • 用于连接到用于插入液体的井管放电管的下端的潜水泵包括用于收集液体的固定收集管和在收集管内的向上和向下往复泵送管,用于将液体推入和提升到排放管中 ; 加压气体源,包括套管和气阀的壳体组件以及具有套管的活塞组件,所述活塞组件包括活塞管,所述活塞管具有连接到泵管的下端,用于往复运动泵管和具有活塞的上部, 在室内与套管的内部移动。 优选地,在向下运动期间,在泵管的向上运动期间泵送相同量的液体。
