摘要
螺管式电磁铁是电磁铁中应用最广、产量最大的一种。由于电磁系统磁场与温度场分布不均匀以及磁性材料性能的非线性等原因,造成吸力计算及温升控制较为复杂。电磁阀设计主要解决的是密封和温升问题,必须对电磁阀、弹簧力和气体压力进行准确计算确保气路的通断,并且保证正常工作情况下的温升。因而电磁铁的电磁力与密封和温升息息相关。采用双线圈,选择合适的软磁材料、电磁铁结构和漆包线设计电磁铁,在通电1h内保证磁力的同时温升不超过100℃。ANSOFT软件仿真及实验证明了优化设计的可行性和有效性。
Solenoid electromagnet is a kind of most extensively used one. Since the uneven distribution of the magnetic and temperature field of electromagnetic system as well as non-linear properties of magnetic materials, its temperature control and suction calculation are very complex. For the design of solenoid valve, the sealing and temperature rise are mainly problems. The accurate calculation of electromagnetic force, spring force and gas pressure is necessary to ensure gas on-off and the control of temperature rise under normal operating conditions. So the electromagnetic force is closely related to sealing and temperature. By selecting proper soft magnetic materials, magnet structure, wire, double-coil electromagnet wasdesigned. The ANSOFT simulation and experiments prove the feasibility and effectiveness of the design.
