Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] figure 1 Shown is an embodiment of the invention. The multi-phase electromagnetic drive coils in this embodiment adopt three-phase electromagnetic drive coils.

[0023] The linear conductive liquid non-contact drive device of the embodiment of the present invention is composed of a cylindrical cylinder, a suction valve, a discharge valve, a three-phase electromagnetic drive coil, a three-phase AC power supply, a three-phase switch and a three-phase protection device. Its structure is as follows figure 1 shown. Such as figure 1As shown, the cylinder body of the linear conductive liquid non-contact driving device is a hollow circular cylinder, and the outer wall of the cylinder body is made of non-magnetic stainless steel sheet. The two ends of the cylinder body are made of non-magnetic stainless steel plates with a certain thickness, ...

Abstract

The invention relates to a non-contact solenoid drive device of a linear conducting liquid. One end part of a cylinder is connected with a connecting pipe of a liquid pipeline by a sucking valve or is directly connected with the connecting pipe of the liquid pipeline, and the other end part of the cylinder is connected with the connecting pipe of the liquid pipeline by a discharge valve or is directly connected with the connecting pipe of the liquid pipeline; multi-phase solenoid drive coils are periodically arranged outside the cylinder from the end of the sucking valve to the end of the discharge valve according a certain phase sequence A, B, C, D...; a multi-phase alternating current power supply has the phase number equal to that of the multi-phase solenoid drive coils and periodically supplies power for the phase winding of the multi-phase solenoid drive coils according to the sequence of first A phase, then B phase, and then C phase...; and the multi-phase alternating current power supply supplies power for the annular multi-phase solenoid drive coils, the annular multi-phase solenoid drive coils generate a three-dimensional magnetic field linearly moving from the end of the sucking valve to the end of the discharge valve in the cylinder, and the relative movement of the magnetic field and the conducting liquid generates induction current and electromagnetic force in the conducting liquid to realize the non-contact drive of the conducting liquid along a certain specific direction.

Description

technical field [0001] The invention relates to a non-contact drive device for conductive liquid, in particular to a linear non-contact electromagnetic drive device for conductive liquid. Background technique [0002] Liquid pumps occupy a very important position in the national economy. Liquid pumps are used wherever there is liquid transportation, from airplanes and rockets in the sky, to drilling and mining in the ground, from land trains, tanks, to sea Ships, submarines, whether it is industry or agriculture, whether it is cutting-edge technology or people's daily life, etc., liquid pumps are needed everywhere. Although liquid pumps with conventional structures have been widely used, there are still two key problems that are difficult to solve: one is the sealing of the conveying liquid in the liquid pump; the other is that the conveying liquid will damage the impeller through cavitation and corrosion. problems, especially for high-speed or high-pressure liquid pumps, t...
