Application of several powerful magnets powerful magnets in the valve has a valve in a certain application, which includes switch-mode and two proportional, and this one powerful magnet switch type is mainly used in directional control valves commutation The system of unloading and loading, and so on; and proportional powerful magnets are mainly installed on various types of proportional valve, often used to control the direction of flow, pressure, and flow rate. Many proportional pressure valve are electronically controlled variable displacement pump mounted on the magnet, which is used to control the flow and direction of the pump. In addition, powerful magnets proportional electromagnetic force also has within its stroke characteristics almost unchanged, the switch can be different from the ordinary type strong magnet. Another major feature of this attraction is through the special shape and guide the work of the guide magnet magnetic air gap formed. The difference between the switch-mode and proportional powerful magnets are not completely dependent on a strong magnet itself proportional powerful magnets at maximum current, it has the equivalent of a switching of powerful magnets, powerful magnets and a switching simultaneously in different currents will produce different thrust. The powerful magnet performance indicators include applicable voltage (current), push (pull) force and itineraries. Then we can roughly be divided into 12 V, 24V DC and 110V, 220V AC and so on according to the voltage. Another powerful magnets push (pull) NG6 force solenoid valve is usually 20 ~ 70N, the stroke is between 3 ~ 7mm. So Liwan magnet manufacturers, it will be able to travel within the above range is to be judged by checking if we suspect that a solenoid valve coil burned or when catching. Parallel powerful magnet magnetic circuit analysis of a cylindrical drum, outside there is a strong magnet ring, placed inside a circular iron (iron outer diameter approximately equal to the inner diameter of the drum), the ability to move up and down the outside by means of powerful magnets to drag move up and down movement of internal iron circular iron plate theory you can overcome gravity and friction with the inner diameter of the drum on it. Steady static magnetic field is the magnetic field produced by a current or permanent magnets. Static magnetic shielding is the use of high magnetic permeability μ shield made of ferromagnetic material in order to shield the external magnetic field. It is similar with the electrostatic shielding effect and there are different. But Longgang magnet manufacturers mentioned circular iron overcome gravity and friction above complex association. Security kid magnet businesses under desks desktop, with powerful magnets to drag on the desktop steel pieces move, magic. No gravity problem.
