Non-contact driving device of rotary type conducting liquid permanent magnet

Abstract

The invention provides a non-contact driving device of a rotary type conducting liquid permanent magnet, which comprises a cylinder body, a suction and discharge one-way valve, a connecting tube, a permanent magnet and a rotary motion driving device of the permanent magnet, wherein the cylinder body is a partially hollow circular body with an arced central line and made from non-magnetic-conducting materials; an outer wall of the cylinder body is a thin wall; the front end part of the cylinder body is connected with the connecting tube of a liquid pipe by a suction valve, and the back end part of the cylinder body is connected with the connecting tube of the liquid pipe by a discharge valve; the permanent magnet is made from permanent magnet materials, arranged outside the outer wall of the cylinder body, and has a certain gap with the outer wall of the cylinder body; the permanent magnet generates a dipolar or multipolar field in the circular cylinder body; the rotary center point ofthe permanent magnet coincides with the geometric center point of a circle in which the central line of the circular cylinder body is located; and the permanent magnet revolvably moves along the central line of the cylinder body under the action of the rotary motion driving device.

Description

technical field [0001] The invention relates to a rotary permanent magnet non-contact drive device, in particular to a rotary permanent magnet non-contact drive device for conductive liquid. Background technique [0002] At present, the widely used liquid pumps mainly include two types: rotary type and reciprocating type. It converts the energy of the prime mover into liquid energy through the rotation of the impeller or the linear motion of the piston, so as to achieve the purpose of transferring liquid. Whether it is a rotary or reciprocating liquid pump, their common feature is that there is a moving part in contact with the liquid. When the prime mover drives the moving part, the part changes the pressure of the liquid, thereby producing the motion of the liquid. When this moving part acts on the liquid, it will affect the liquid, for example: the impeller of a blood pump will cause hemolysis, and the liquid will also damage the moving parts through cavitation and corro...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art that the moving parts in the liquid pump must be in direct contact with the liquid, resulting in bad interaction, and propose a rotary conductive liquid permanent magnet non-contact drive device
