What factors will cause the solenoid valve of the ultrapure water machine to fail to close?

     The operation of ultra-pure water machines mostly adopts pretreatment, reverse osmosis technology, ultra-purification treatment and post-treatment methods to almost completely remove the conductive medium in the water, and also remove the non-dissociated colloidal substances, gases and organic substances in the water to a certain extent. Very low level of water treatment equipment. The resistivity of ultrapure water produced by it should generally be greater than 10 megohms, and water above 10 megohms is called ultrapure water. The better ultrapure water effluent can reach 18.25 megohms.

In the process of using the ultra-pure water machine, various failures will inevitably occur, and it needs to be dealt with in time according to the correct solution to operate normally. Below we will bring you the solenoid valve of the laboratory ultra-pure water machine. Can't close the problem.

The solenoid valve of the ultrapure water machine cannot be closed usually due to the following reasons:

1. The main valve core and moving iron core may be damaged. Check the working status of the main valve core, moving iron core and seals, and whether they really need to be cleaned or replaced.

2. The temperature of the source water becomes high, the viscosity of the source water is too high, and the corresponding solenoid valve should be replaced in time.

3. The spring in the solenoid valve may be deformed and needs to be replaced in time.

4. After removing the solenoid valve, blow it hard along the direction of the water flow to see if there is a transparent phenomenon. If it occurs, you need to contact the after-sales personnel to replace the solenoid valve.

5. Check whether the balance hole and throttle hole of the ultrapure water machine are blocked.

6. Check whether the solenoid valve is installed correctly. If the solenoid valve is installed reversely, you need to reinstall the solenoid valve.

The above are the main reasons why the solenoid valve of the ultrapure water machine cannot be closed. Only by understanding the causes can we better solve this problem.
