ASCO Type Repair Kit Armature Plunger K0850 for Pulse Jet Valve

Because there is no hysteresis eddy current loss in dc electromagnet, the core can be made of the whole ferromagnetic material. Moving iron core is often made of cylindrical, known as i-shaped or spiral tube type electromagnet, compared with t-shaped electromagnet, compact structure, small volume, short travel, moving parts light, small impact force, air gap all in the spiral pipe ring, generating greater suction. But the direct current electromagnet must prevent the residual magnetism from being too large to affect the normal work.

Hysteresis eddy current loss exists in the core when ac electromagnet passes through alternating current. On the small electromagnet and the electromagnetic pilot valve, the integral I electromagnet can be used. In order to reduce iron consumption and heating, t-shaped electromagnet is often used on the direct-moving solenoid valve which needs a larger attraction. Its iron core is made of silicon steel sheet to reduce iron consumption and heating. T - shaped electromagnet movable parts of the weight, action, the impact force, but the suction force, travel.

Starting current and holding current

When the voltage of ac electromagnet is fixed, the exciting current is mainly affected by the stroke, although it is related to the resistance of coil. Big travel, big reluctance, big exciting current. The current at the maximum stroke is called the starting current, while the current at the moment of absorption is called the holding current, also called the excitation current. In large electromagnets, the starting current can be more than 10 times the holding current.

The starting current of small electromagnet can also reach 2 to 4 times of holding current. If the moving iron core is stuck and the starting current continues to flow, the coil will become extremely hot and even burn out. Small travel of the electromagnetic pilot valve is not easy to burn out. Ac electromagnet should not be switched on and off frequently. Not as long as dc electromagnet.

When the voltage is constant, the coil current of the dc electromagnet depends only on the coil resistance, and has nothing to do with the travel size. The moving core will not burn the coil when it gets stuck. Dc electromagnet can be frequently on and off, safe and reliable work. However, the wrong high voltage, flow through the current is too large, will still burn out the coil.

The relationship between suction and travel

The relationship between electromagnetic suction and travel (i.e. air gap) is called suction characteristics. The relationship between spring force and gravity is called reaction characteristic. It is hoped that the electromagnet under any stroke, the suction force is slightly greater than the reaction force, which can ensure the moving iron core absorption, and avoid the action speed too fast to cause impact and rebound. This can avoid contact welding and burning, to improve the life. The suction force of the dc electromagnet is inversely proportional to the square of the travel. The suction characteristic curve of ac electromagnet is relatively flat, that is, it has larger suction force when the travel is large.
