Analysis of Structure and Common Faults of Industrial Chiller Water Solenoid Valve

Air-cooled chiller | Water-cooled chiller | Screw-type chiller | Shenzhen chiller- Shenzhen Dongyuejin chiller factory on the structure of the industrial chiller solenoid valve and common failure analysis: solenoid valve is composed of electromagnetic coil and magnetic core, when the coil When the power is turned on or off, the operation of the magnetic core will cause the fluid to pass through the valve body or be cut off to achieve the purpose of changing the direction of the fluid. The electromagnetic components of the electromagnetic valve are composed of fixed iron cores, moving iron cores, and coils. The valve body consists of a slide valve core, a slide valve cover, and a spring base.

After a long period of operation of an industrial chiller, it is normal for parts and components to wear. If the solenoid valve of the chiller does not work, the operation of the switching valve and the regulating valve may be affected, and the operation of the entire chiller is affected. Therefore, the operator of the chiller should regularly check and record the relevant data, so that the problem can be found in time. Solve the problem.

The common faults of solenoid valves are the following:
1, the power supply voltage is too low, so that the solenoid valve can not normally open, work;
2, poor circuit contact, that is, open circuit or coil short circuit, so that the solenoid valve can not work, can be used multimeter test;
3. The installation direction of the solenoid valve is reversed, that is, the flow direction of the fluid is opposite to the flow direction required by the solenoid valve, so that the valve closing is not strict;
4, the solenoid valve chip has dirt, so that the chip stuck, causing close or not closed;
5, the pressure difference between the inlet and outlet of the fluid is greater than the valve opening capacity, so that the solenoid valve cannot be opened;
6, the electromagnetic valve seal gasket damage or slide valve wear caused by several cavity helium, will cause air pressure is insufficient, making it difficult to open and close the forced valve.

Although the solenoid valve is only a small and small part of the industrial chiller, its role is unmatched. Therefore, Dongyuejin Chiller Factory mainly uses the American ALCO brand solenoid valve to ensure its quality while ensuring its safety.
