Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] The permanent magnet non-contact driving device of the conductive liquid in the embodiment of the present invention is composed of a cylinder body, a suction valve, a connecting pipe, a permanent magnet and a reciprocating driving device of the permanent magnet, and their structures and relative positions are as follows figure 1 shown.

[0018] Such as figure 1 As shown, the cylinder body of the permanent magnet non-contact driving device is a hollow square, rectangular, polygonal, circular or elliptical cylinder, and its outer wall is made of non-magnetic, non-conductive or non-magnetic, low-conductivity, thin metal or made of non-metallic materials. The two ends of the cylinder are made of metal or non-metal material with a certain thickness to ensure sufficient rigidity and strength of the cylinder. The left end of the cylinder is ...

Abstract

The invention discloses a reciprocating conducting liquid permanent magnet contactless driving device, which consists of a cylinder body, an inhalation valve, two connecting pipes, a permanent magnet and a reciprocating driving device for the permanent magnet, wherein the cylinder body is a hollow cylinder; an outer wall of the cylinder body is made of a non-magnetism-conducting non-conducting or non-magnetism-conducting low-conductivity thin metal or nonmetallic material; two end parts of the cylinder body are made of metal or nonmetallic materials with certain thickness; a left end part of the cylinder body is connected with a connecting pipe of a liquid pipeline through the inhalation valve; a right end part of the cylinder body is connected with the other connecting pipe of the liquid pipeline; conducting liquid is filled in the cylinder body; and the permanent magnet is positioned at one end outside the cylinder body and linearly reciprocates along an axial direction of the cylinder body under the driving of the reciprocating driving device for the permanent magnet.

Description

technical field [0001] The invention relates to a non-contact driving device, in particular to a non-contact driving device for conductive liquid. Background technique [0002] A liquid pump is a machine that converts the energy of the prime mover into liquid energy. It mainly has two types: rotary and reciprocating. There are three types of rotary liquid pumps: centrifugal pump, axial flow pump and mixed flow pump. Its prime mover drives the impeller to rotate through the pump shaft, and does work on the liquid to increase its energy to transport the liquid. The reciprocating liquid pump consists of two parts: the pump body and the prime mover, and the pump body can be divided into two parts: the liquid end and the transmission end. The hydraulic end mainly includes discharge valve, suction valve (or suction window), pump cylinder and cylinder liner, piston (or plunger), sealer, various connecting pipes and compensation pipes. Its function is to compress the liquid in the...
