高速开关阀电磁铁设计及磁力特性研究
Design and Magnetic Characteristics Study of High-speed On/Off Valve Electromagnet
摘要
Abstract
The electromagnet is the electromechanical conversion device of high-speed on/off valves,which achieves rapid response of high-speed on/off valves through the rapid opening and closing of valves.The performance of the electromagnet directly affects the dynamic characteristics of high-speed on/off valves.Therefore it is crucial to research the design and magnetic characteristics of the electromagnet.Based on this,this study carried out the structural design of high-speed on/off valve electromagnet,established the magnetic field model of the electromagnet,analyzed the magnetic field law of the electromagnet,and obtained the magnetic characteristics of the electromagnet.The results show that the maximum electromagnetic force of the electromagnet is about 28.0 N,the magnetic field establishment time is about 15 ms,and the magnetic field disappearance time is about 20 ms in the separated state.In the suction state,the maximum electromagnetic force is about 45.7 N,the magnetic field establishment time is about 15 ms,and the magnetic field disappearance time is about 50 ms.Under the separated and suction states,the steady-state electromagnetic force experiment and simulation average errors are less than 2.5%,and the experimental results are consistent with the design expectations.The structural gap has a significant impact on the performance of the electromagnet.Increasing the moving iron core and reducing the air gap can increase the electromagnetic force.关键词
