Accurate control on different components, the flow amount, the flow direction and the flow speed of the conductive liquid can be realized, and the conductive liquid micro driving device has the advantages that the overall structure is compact; the device is flexible and deformable; pressed driving does not exist; no push rod mechanism is needed; the pipeline can be cleaned by itself; assembly and disassembly are convenient; the space utilization rate is high; the application range is wide; the use is simple; portability is realized; the noise is small; the service life is long and the like.

Description

technical field [0001] The present invention relates to a liquid delivery device and its application, in particular to a liquid driving motor and its application, and also to a liquid micro-injection and distribution device and its application, which are used in biomedicine, chemical engineering, material synthesis, fluid transportation, Liquid micro-drive control technology field such as food processing. Background technique [0002] Linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. Generally, it can be considered that the linear motor is evolved from the ordinary rotary motor. The cylindrical stator and rotor of the rotary motor are cut and straightened along the axial direction to form a linear motor with a flat plate mechanism, and then the flat primary and secondary Winding on an axis parallel to the moving direction of the magnetic field, flat, cylindrical,...

AI Technical Summary

Problems solved by technology

The laminated structure is generally assembled by 4 to 6 sets of independent iron cores, the primary eddy current loss is reduced, but its structure is complex and difficult to assemble

The horizontal lamination type and the silicon steel sheet type are simple in structure, easy to manufacture, and are also widely used. The main disadvantage is that the eddy current loss of the iron core is large, which greatly reduces the efficiency of the motor.

The eddy current loss of the laminated window structure is small, but the processing cost is high

[0005] The traditional linear induction motor not only has the above-mentioned serious current loss problems, but also has a bloated device and limited structural form, so it cannot be used in miniature or complex equipment.

In view of the above technical problems, it is a technical problem to be solved urgently to provide a new type of conductive liquid micro-drive method that can overcome the defects of the above-mentioned devices that are bloated and have limited structural forms.
