Singlestage and multistage electromagnetic revolutionary piston pump

Abstract

An electromagnetic revolutionary piston pump is disclosed. The electromagnetic revolutionary piston pump includes an inner tube, an outer tube, two annular separation plates, a plurality of pistons, and an electromagnetic coil. The inner tube has a plurality of first and second through holes, and it accommodates the abovementioned pistons to revolve inside. The outer tube has an intake opening and an exhaust opening, and it wraps the inner tube inside. In addition, the annular separation plates are disposed inside the outer tube for dividing the inner space of the outer tube into a first airproof space and a second airproof space. The first airproof space connects the intake opening and communicates the inner space of the first tube via the first through holes; the second airproof space connects the exhaust opening and communicates the inner space of the first tube via the second through holes. Moreover, the electromagnetic coil is mounted on the wall outside of the inner tube in the first airproof space for exerting magnetic force onto the pistons.

Description

BACKGROUND OF THE INVENTION [0001] (a) Field of the Invention [0002] The present invention relates to a piston pump and, more particularly, to an electromagnetic revolutionary piston pump. [0003] (b) Description of the Related Art [0004] An air pump is a device used to increase air pressure by reducing volume of the air. Air pumps are usually classified into three types—reciprocating, centrifugal, and axial-flow, and the reciprocating type is most commonly used due to its' ability to obtain a wide pressure range. [0005] A reciprocating pump is also called a reciprocating piston pump for that it has a piston reciprocating in a fixed space to compress air and thus increase pressure. Presently, electromagnetic force is often used to drive the piston, as illustrated in FIG. 1, to gain larger air pressure from the reciprocating piston pump. [0006] However, the reciprocating piston pump illustrated in FIG. 1 has the following disadvantages. Firstly, the pressure distribution is discontinu...

AI Technical Summary

Benefits of technology

[0009] Another object of the invention is to effectively increase airflow and pressure and to improve reciprocating piston pump efficiency.

[0010] Another object of the invention is to effectively reduce number of parts in electromagnetic reciprocating piston pumps and to make the reciprocating pump size smaller.

[0017] Through the design of the invention, the electromagnetic revolutionary piston pump is able to: 1. have continuous air pressure and increased airflow; 2. avoid the usage of parts like back-pressure valve, and thus effectively reduces the number of pump parts used and the pump size; 3. lower the energy loss in the system, and hence increases work efficiency and reduces working cost.

Problems solved by technology

Secondly, an extra pressure storage tank is often needed for the pump to get a stable and continuous pressure.

Thirdly, the back-pressure valves constraining airflow direction, the intake valves, and the exhaust valves provided inside the reciprocating piston pump are made of many parts, which not only complicates the whole system but also makes the system difficult to maintain.

Fourthly, the friction produced during reciprocation of the piston consumes a large amount of kinetic energy of the piston, results in more energy provision for the piston, and thus leads to an increase in working cost and a decrease in work efficiency.
