Comparative Analysis of Static Solenoid Force Magnitude of Two Different Structures of Static Iron Core Solenoid Valves
In order to compare the applicable scenes and the magnitude of static solenoid force generated by solenoid static iron core solenoid valve and pole static iron core solenoid valve.Firstly,the finite element model of the two types of static iron cores is established and the model is verified through experiments,and then the static solenoid force of the two types of structures is compared in different currents and under different air gaps.Through the calculation and analysis,it is concluded that in the same shape and volume,solenoid force generated by solenoidal static iron core steadily increases with the increase of coil current.Because the coil temperature is too high when the current is too high,under the working condition of 40 A current,the coil temperature reaches 186.2 ℃.It is suitable for small current and small stroke working situation.While the solenoid force generated by the pole static iron core solenoid valve rises faster and is also larger with the increase of the coil current,and the bare single-layer coil ensures heat dissipation,under the working condition of 40 A current,the temperature is only 51.1 ℃.It is suitable for large current and large stroke working situation.Meanwhile,the pole static iron core solenoid valve solenoid force increases first and then decreases with the increase of the number of poles.Under the same conditions,six-pole static iron core solenoid valve generates the largest solenoid force and it provides theoretical guides for the design of new high-speed solenoid valve static iron core.
