Description

technical field [0001] The invention relates to the technical field of electromagnetic pump design, in particular to a high and low pressure fixed molding system for an electromagnetic pump. Background technique [0002] Electromagnetic pump is a pump in which the current-carrying fluid in the magnetic field flows in a certain direction under the action of electromagnetic force. The electromagnetic pump is a device that uses the interaction between the magnetic field and the current in the conductive fluid to cause the fluid to generate a pressure gradient under the action of electromagnetic force, thereby pushing the fluid to move. The electromagnetic pump has the characteristics of compact structure, high output pressure, relatively low price and good dynamic adjustment characteristics. Zinc alloy hub adopts different pressure modes during filling and solidification to achieve complete compactness and high performance of zinc alloy hub, and can avoid zinc alloy hub high-p...

AI Technical Summary

Problems solved by technology

At present, there is no molding process for zinc alloy wheels, and the low-pressure casting process is generally used. The traditional aluminum alloy low-pressure casting molding process is used, which has low sealing performance and short production time. Zinc alloys are easily oxidized, resulting in increased costs.

For related technical problems, no effective solutions have been proposed
