Problems solved by technology

However, after various pumps have been in operation for a period of time, the gap between the shaft and the seal will inevitably increase, or the seal will gradually fail due to aging, and the fluid in the pump chamber may flow out from the gap to cause damage.
Therefore, people have to carry out cumbersome time-consuming, labor-intensive and costly work on various types of pumps such as frequent maintenance and replacement of seals; A fundamental technical problem that has existed for a long time in machine use
In some special fields that require the use of motors (or generators), the overall size of the traditional rotating motor plus the transmission machinery is large and heavy, and it is very inconvenient to connect the machine tool (executive machinery) to use, such as the electric car. The connection, installation and use of the motor and the wheel, etc.
Moreover, the complex structure of traditional rotating electrical machines (including AC and DC motors and generators, etc.) also makes its manufacturing technology more complicated, time-consuming and material-intensive

Embodiment Construction

[0015] The specific implementation methods of various types of electromagnetic force coupling drivers can be as follows:

[0016] The composition of the electromagnetic force coupling drive is to turn the traditional rotating electrical machine (including AC and DC motors and generators, etc.) The air gap space between the surface of the primary stator and the surface of the secondary rotor is turned over from the initial position 0° to 180°, and the turning angle is correspondingly at the position A of 90°, the position of B is greater than 0° but less than 90°, and the position of C When it is greater than 90° but less than 180° and the D position is 180°, it constitutes four types of electromagnetic force coupling drivers with different structures, namely A-type, B-type, C-type and D-type), and from the end where it starts to flip along the radial direction It is evenly distributed and cut into several equal parts until it is the circumferential line at one end of the overt...

Abstract

The present invention relates to an electromagnetic force coupling driver and an inorganic shaft hole pump formed thereof, and a permanent magnetic force coupling driver and an inorganic shaft hole pump composed thereof. Electromagnetic force coupling driver is an integrated device of electricity, magnetism and machine that can directly realize mutual conversion of electric energy and mechanical energy, and permanent magnetic force coupling driver is an electromechanical device that uses permanent magnetic force coupling and transmission. The pump without shaft hole, that is, there is no need to open a shaft hole on the pump volute to directly connect the impeller shaft with the external transmission machinery, but a new type of pump shaft is driven by a magnetic coupling driver and mechanical torque and power are transmitted to it. Pump machine; the machine no longer has the problem of fluid leakage and sealing in the pump chamber because of the absence of shaft holes.

Description

technical field [0001] The present invention relates to a magnetic coupling driver which is coupled by electromagnetic force or permanent magnetic force and transmits electromagnetic force torque, mechanical torque and power, that is, a motor device which integrates electricity, magnetism and machine and can convert electric energy and mechanical energy. ; and a shaft-hole-less pump made of it, that is, a new pump that does not leak fluid in the pump chamber from the shaft hole. Background technique [0002] In the prior art, centrifugal pump machines are all driven by traditional rotating motors and connected into one body. Large and medium-sized pumps are generally composed of couplings or various transmission mechanisms to connect the motor shaft and the pump shaft, and there are many seals to seal the gap between the pump shaft and the volute, so that The fluid in the pump chamber cannot permeate through the gap between the rotating shaft and various seals and flow out ...
