When the metal spacer is used in the previous technology, the spacer is in a sinusoidal alternating magnetic field, and the eddy current is induced on the section perpendicular to the direction of the magnetic force line and converted into heat, which will have a very negative impact on the life of the pump. To solve this technical problem, the Future R&D team found a high-quality carbon fiber material to replace metal after long-term research and exploration. T300, T700, and T800 grade carbon brazing materials can produce carbon fiberrear shellcomposite insulation reinforcement sleeves according to the drawings according to customer needs by molding, winding, and autoclave processes. The carbon fiberrear shell isolation reinforcement sleeve is durable and magnetically permeable and has a pronounced effect in reducing eddy currents. Compared with ordinary pumps, the working efficiency is increased by 5%-8%, and the weight of the spacer is only a quarter of the original metal spacer.
