AIR PRESSURE DIFFERENCE TYPE ENERGY SAVING WATER PUMPING DEVICE

摘要

An air pressure difference type energy saving water pumping device mainly includes: a water tower (1) provided with an electrogeneration equipment (14) and a civil use water pipe (18); an air pressure difference pump (2) which is divided into a left cylinder (20), a right cylinder (20) and their correlating components; a group of water pumping pipes (3) as the connection for the water cycle between the air pressure difference pump (2) and the water tower (1); a water storage tank (4) for supplying water to the left and right cylinders (20); a compressed air supplying controller (5) which can control suction/exhaust of the compressed air in order to drive the air pressure difference pump (2) ; left and right air intake pipes (25) for introducing the compressed air into left and right equivalent diameter collapsible cylinder tubes (230) in order to drive the pistons (200) of the left and right cylinders alternate in turn to pump water, then the water in the air pressure difference pump (2) can be pumped into the water tower (1). Thereby the device can be applied to water replenishment automatic control needed by hydraulic electrogeneration or water supply system.
