Solutions to various problems in ultrapure water systems
1. There is a problem with water quality, and what factors are related to it
1) Functional consumables are due, especially DI column or RO membrane;
2) The equipment parameters are unreasonable and need to be adjusted (RO);
3) Customer source water quality deterioration (RO);
2. In the event of a power outage, the machine will not start normally when it is restarted. What causes this situation and what needs to be paid attention to
Ultrapure water systems generally do not have this problem. Our machine is not afraid of sudden power failure. If so, you can try to manually re-energize and start it again. If it doesn’t work, there is a problem with the electric control board;
3. How to judge whether the RO membrane is broken or the problem of the RO membrane sealing ring. If there are problems with both, there will be those conditions
1) The problem of the sealing ring of the ultrapure water system usually leads to very poor water quality, and it can be basically confirmed that the membrane is no problem, such as a new membrane. Of course, the membrane module can also be removed to check the deformation of the sealing ring;
2) The damage of the RO membrane is a slow process and cannot occur suddenly, that is, the water quality will not deteriorate suddenly, but gradually deteriorate, usually accompanied by a decrease in water volume, an increase in system pressure and other complications.
4. The internal structure of the water machine (such as the relevant knowledge and functions of a specific component)
5. Reasons corresponding to specific failures, possible problematic accessories and their simple inspection methods
1) The simplest method is the elimination method. First, analyze the possible faulty components according to the flow chart, and then use manual or other auxiliary small parts to temporarily replace a possible faulty component to simulate the operation, and check the troubleshooting to judge;
2) For common non-hardware faults, we usually analyze, judge and deal with them by checking the routine indicators in the maintenance report. Familiarity with the equipment’s workflow can help us judge the source of the fault well.
