Description
Technical Field
The invention relates to an alternating-current abrasive magnetic fluid jet generating device, in particular to an alternating-current abrasive magnetic fluid jet generating device based on a permanent magnet.
Background
The jet flow of the pre-mixed abrasive has the characteristics of low pressure portability because the abrasive has secondary acceleration, and the jet flow quality is superior to that of the post-mixed abrasive. However, because the volume of the grinding tank is limited, continuous work cannot be ensured in the jet process, and the application of jet technology is limited. The post-mix abrasive jet can work for a long time because the abrasive is added at the nozzle. However, because the working pressure required by post-mixing is high, the damage to the sealing element is serious, and the quality of abrasive jet is not the same, so that the development of the abrasive jet is restricted.
The interaction between the current and the magnetic field is utilized to enable the conductive fluid mixed with the abrasive to generate high-speed jet technology, namely abrasive magnetic fluid jet under the action of electromagnetic force. In 1962, america Owen M.Phillips first proposed the idea of alternating magnetic fluid propulsion. The traditional alternating current type abrasive magnetic fluid jet flow needs a superconducting coil to be electrified to generate a traveling wave magnetic field, so that the abrasive magnetic fluid generates induction current, and is propelled and ejected to form the jet flow under the action of electromagnetic force. Because the energy consumption of the superconducting coil is high, the prior art is still immature, and a generating device capable of replacing the superconducting coil needs to be provided.
