Piston type water-pumping device

Abstract

The invention discloses a piston type water-pumping device. The piston type water-pumping device comprises a cylinder block and a motor, wherein the cylinder block is supported on the water surface through a floater; a piston plate capable of moving upwards and downwards in a reciprocating way is arranged in the cylinder block; the piston plate is provided with a water outlet; a valve I is arranged at the water outlet; the piston plate is connected with the motor through a crank connecting rod mechanism; the upper side of the cylinder block is open, and the periphery of the opening is connected with a water pan; the water pan is connected with a water outlet tube; the lower end of the water pan is connected with a water inlet tube; the water inlet tube is provided with a valve II. The device has very high working efficiency, and the problem that a large amount of electric energy is unavoidably converted into kinetic energy or pressure energy of pumped water in a power type or volumetric water-pumping device is solved.

Description

technical field [0001] The invention relates to a water pumping device, in particular to a piston type water pumping device. Background technique [0002] Most of the existing pumping devices are power pumps. Power pumps are also called impeller pumps or vane pumps. They rely on the force of the fast-rotating impeller on the liquid to transfer mechanical energy to the liquid, increasing its kinetic energy and pressure. Then through the pump cylinder, most of the kinetic energy is converted into pressure energy to realize delivery. Centrifugal water pumps are the most common dynamic water pumps. Dynamic water pumps generally have no self-priming ability. It is necessary to fill the pump cylinder with liquid or evacuate the pipeline before starting to work. In addition, during the working process, a large amount of electric energy is converted into kinetic energy of water, resulting in excessive power consumption. The disadvantage of a large amount. Existing water pumping d...

AI Technical Summary

Problems solved by technology

Dynamic water pumps generally have no self-priming ability. It is necessary to fill the pump cylinder with liquid or evacuate the pipeline before starting to work. In addition, during the working process, more electrical energy is converted into kinetic energy of water, resulting in excessive power consumption. Disadvantages of large quantity

Existing water pumping devices also include positive displacement pumps, which have self-priming capabilities, but when the positive displacement pumps press the liquid out of the pump cylinder, the pressure energy will consume part of the potential energy, resulting in a waste of energy, which cannot be maximized. The kinetic energy of the piston movement is converted into the potential energy of the water, which reduces the efficiency of pumping water.
