What to do if a chemical industry ultra-pure water system stops operating suddenly

Thread Content

　　After a chemical ultra-pure water system has been in use for some time, various factors, whether human-induced or otherwise, can cause certain malfunctions in the equipment. As users, one certainly hopes that the equipment will never experience problems, but this is almost impossible. So when a problem occurs, the first thing to do is to rule out external issues. For example, if the device will not start, basic checks can be carried out to see whether the power supply is properly connected, whether the connectors are loose, and whether there is power supplied to the device. After that, we examine whether there are internal problems with the device, such as damaged components or blockages in consumable parts. 　　Sometimes, many faults and problems are actually caused by improper operations on the part of the operators. However, when the equipment fails to start, on-site testing should be carried out first to determine whether corrosion resulting from iron ions entering the booster pump is the cause. If this is indeed the case, the booster pump must be stopped immediately, and the pressure switch as well as the water pipes need to be thoroughly cleaned before the equipment can be restarted.
