Gravity supercharging water feeding machine

Abstract

The invention discloses a gravity boost water delivery machine, and relates to high-rise water delivery, water storage, water supply, electricity generation by water energy and other application of water energy. According to the basic structure and principle of the prior volume delivery single-cylinder single-acting reciprocating pump, the invention develops a working piston rod into a water storage cylinder, and combines the water storage cylinder and a piston into a piston assembly capable of storing and emptying water to replace the prior piston rod; when the piston assembly works, water source without drop height is led into the water storage cylinder of the piston assembly, so as to increase the weight of the water storage cylinder, improve kinetic energy of the piston descending gravity speed, and achieve the improvement of gravity boost horsepower; at the same time, the vacuum generated when the piston assembly ascends to enlarge the volume and reduce the pressure of a working chamber thrusts aside an emptying valve on the piston assembly and the water in the water cylinder is emptied into a working chamber of a pump cylinder, so as to lighten the ascending weight of the piston assembly to achieve reset after the emptying, and further realize effective energy conservation of the gravity boost water delivery machine in the water delivery process.

Description

technical field [0001] The invention relates to the technical field of high-rise water delivery, water storage, water supply, hydropower generation and other hydropower applications Background technique [0002] The technical structure of the existing volumetric single-cylinder single-acting reciprocating pump is composed of: pump cylinder, piston, piston rod, discharge valve, suction valve, power machine, reducer and so on. [0003] The working principle of the existing volumetric single-cylinder single-acting reciprocating pump: when the piston moves upward, the working volume of the pump cylinder expands and the pressure decreases to generate a vacuum, the suction valve opens, the liquid is sucked into the outlet, and the valve closes; when the piston moves downward, the pump cylinder The volume of the working chamber decreases, the pressure rises, the suction valve closes, the outlet valve opens and the liquid is discharged, the piston keeps reciprocating, and the liquid...
