Static force hydroenergy water feeder

Abstract

The invention discloses a static force hydroenergy water feeder which is suitable for the water source recycling field including municipal first water supply, high-rise secondary pressure water supply, circulating cooling water, construction water saving, water storage and hydropower, drought resisting, surface water draining and the like. Pressure generated by U-type fluid static force in a pressure balance process serves as a high-potential-energy kinetic energy source for water feeding, the basic structure and the basic principle of a volumetric single-cylinder-body reciprocating pump are combined, a working piston rod is designed to be a water storage cylinder, and a piston assembly capable of storing water and feeding water is composed of the working piston rod and a piston. When a high-head water source passes through the working piston rod, the static force of the water source is converted into a dynamic force with pressure to improve gravity speed kinetic energy of the piston when the piston moves down, not only is static force pressurizing power promoted when the piston moves down, but also the piston assembly is driven to move down rapidly, an external water source flowing into the water storage cylinder of the piston assembly is pushed, and the purpose of the water feeding which is low in energy consumption, efficient and energy-saving is achieved.

Description

technical field [0001] The invention relates to a hydrostatic water energy water supply device suitable for the fields of water resource circulation and reuse, such as municipal primary water supply, high-rise secondary pressurized water supply, air-conditioning circulating cooling water, water storage, hydroelectric power generation, drought resistance and stain removal. Background technique [0002] Existing water supply mode is to realize by adopting volumetric single-cylinder single-acting reciprocating pump. Its working principle: when the piston moves upward, the volume of the working chamber of the pump cylinder expands, the pressure drops to generate a vacuum, the suction valve is opened, the liquid is sucked into the outlet, and the outlet valve is closed; when the piston moves downward, the volume of the working chamber of the pump cylinder decreases , the pressure rises, the suction valve closes, the outlet valve opens, and the liquid is discharged. The reciproca...
