15mm Wire Lead Type DC24V/12V Refrigeration Coil AC220V Chiller Electric Valve Solenoid Coil

The coil of the solenoid valve passes Faraday's law, and after the energization, magnetic lines of force are generated, and then the magnetic lines of force cause the two metals inside to attract each other, thereby generating an action. The solenoid coil is established by the presence of a magnetic field around the wire, and is wound into a spiral-shaped reinforcing magnetic field, that is, the minimum magnetic field is used to achieve the highest magnetic field strength, and the wire coated with a layer of insulating varnish is used instead of the ordinary wire to save space.

Electromagnetic forming can effectively improve the forming properties of lightweight alloys, and the coil structure is one of the key factors affecting the forming quality. It is necessary to determine the distribution of the electromagnetic force according to the needs of the deformation part of the workpiece and design a coil suitable for it.

Daily solenoid valve with coils problem solving of low temperature chiller:

The solenoid valve used in the low temperature chiller is composed of a solenoid coil and a magnetic core, and is a valve body including one or several holes. When the coil is energized or de-energized, the operation of the core will cause fluid to pass through the valve body or be severed to achieve the purpose of changing the direction of the fluid. If the solenoid valve does not work, it will directly affect the action of the chiller switching valve and the regulating valve. When the low temperature chiller solenoid valve does not work, Hailingke Xiaobian should be investigated from the following four aspects:

1. The solenoid valve terminal is loose or the wire ends are off. The solenoid valve is not allowed to be energized and the wire ends can be tightened.

2, the solenoid valve is stuck: the sliding gap between the sliding valve sleeve and the valve core of the low-temperature chiller solenoid valve is very small, generally one-piece assembly, when mechanical impurities are brought in or the lubricating oil is too small, it is easy to get stuck. The treatment method can use a steel wire to break in from the small hole of the head to make it bounce back. The fundamental solution is to remove the solenoid valve, take out the valve plug and the valve core sleeve and clean it, so that the valve core can move flexibly in the valve sleeve. When disassembling, pay attention to the assembly sequence of each component and the external wiring position, so as to reassemble and wire correctly, and check whether the oil mist injection hole is blocked and the lubricating oil is sufficient.

3. Air leakage: Air leakage will cause insufficient air pressure, which makes the forced valve open and close difficult. The reason is that the gasket is damaged or the spool is worn out, causing several cavity helium. When dealing with the solenoid valve failure of the switching system, the appropriate timing should be selected, and the solenoid valve should be processed when the power is lost. If the processing is not completed within one switching gap, the switching system can be suspended and taken care of.

4. The solenoid valve coil is burnt out: The wiring of the solenoid valve can be removed and measured with a multimeter. If the circuit is open, the solenoid valve coil is burnt out. The reason is that the coil is damp, causing poor insulation and magnetic leakage, causing the current in the coil to be too large and burning, so it is necessary to prevent rainwater from entering the solenoid valve. In addition, the spring is too hard, the reaction force is too large, the number of coil turns is too small, and the suction force is insufficient to cause the solenoid valve coil of the low temperature chiller to burn. For emergency handling, the manual button on the coil can be turned from the “0” position to the “1” position during normal operation, causing the valve to open.
