Best.No.0210 13mm Hole Fengshen Refrigeration Solenoid Valve Coil

Best Nr.0210B Refrigeration Solenoid Coil 13 mm x 40 mm is an solenoid coil widely used on a refrigeration solenoid valve. The movable iron core in the solenoid coil is attracted by the solenoid coil when the refrigeration solenoid valve is energized, and the spool is moved to change the refrigeration solenoid valve on state.

The principle of Best Nr.0210B Refrigeration Solenoid Coil:

It is established by the existence of magnetic field around the wire, and it is wound into a spiral to strengthen the magnetic field, that is, the minimum magnetic field is used to achieve the highest magnetic field strength. The wire with a layer of insulating varnish on the surface is used instead of the ordinary wire. save space. The inductance of an air-core coil is different from the inductance of the core after the core is added. The former is small and the latter is large. When the coil is connected to alternating current, the impedance generated by the coil is different. When the AC power of the same frequency is added, the inductance will vary with the position of the core, that is, the impedance changes with the position of the core. When the impedance is small, the current flowing through the coil will increase.

According to the classification of the current through the solenoid coil, there are two kinds of DC electromagnets and AC electromagnets. Let's make a comparison between them.

Humming:

For 50 Hz AC, there are 100 suctions per second of zero. Due to the loss of suction, the moving iron core began to return to its original position. However, in a short time, the suction force increases again, and the moving iron core rejoins, forming a moving iron core to vibrate and beep. A precaution is to provide a magnetic separation ring on the suction surface of the electromagnet. The magnetic flux in the magnetic pole surrounded by the magnetic separation ring is sometimes inferior to the magnetic flux in the unsurrounded magnetic pole, and the corresponding suction force is sometimes poor, so that the total suction force of the movable iron core at any time is not zero, and the vibration can be eliminated. The smaller the resistance of the magnetic separation ring, the better (for example, brass, copper), but too small, the current flowing through the magnetic separation ring is too large, and the loss is large. Setting the magnetic separation ring naturally reduces the mechanical strength. Since the magnetic ring is often broken, the life is shortened. The DC solenoid does not click.
