Abstract

A magnetically suspended piston pump comprises a cylinder made of cylindrical permanent magnet, a piston made of circular permanent magnet, and a circular magnetic plate located at an end of the cylinder, in which an outer surface of the piston has an identical magnetic polarity with an inner surface of the cylinder, and a surface of the circular magnetic plate towards an inside portion of the cylinder has an identical magnetic polarity with a surface of the piston facing to the circular magnetic plate.

Description

[0001] This application claims the benefit of Chinese Patent Application No. 200410051345.6 filed which is explicitly incorporated by reference in its entity. TECHNICAL FIELD OF THE INVENTION

[0002] This invention relates to a piston pump, and more particularly to a magnetically suspended piston pump. BACKGROUND OF THE INVENTION

[0003] In the prior art, a piston pump typically comprises a cylinder, a piston, an inlet valve and an outlet valve located in the cylinder, and a driving mechanism connected to the piston. The driving mechanism usually comprises a crank connecting rod, a vapor device, and a magnetic connecting rod driving device, etc. According to the number of the cylinders or the number of the inlet / outlet valves, the piston pump may be classified as a single-cylinder, a double-cylinder and a triple-cylinder piston pump, or as a single-purpose and a double-purpose piston pump.

[0004] The conventional piston pump has disadvantages that it is of a relatively short service l...
