How to judge whether laboratory ultrapure water equipment needs maintenance?

Proper use of laboratory ultrapure water equipment can make the equipment last longer, and the performance of the water is guaranteed to be greater. However, if you do not follow the operating instructions during use, it will not only affect the quality of the effluent from the equipment. Increased the difficulty of equipment maintenance. How to judge whether the laboratory ultrapure water equipment needs maintenance? The specific performance is as follows:

1. Reduced water production

Under normal pressure, if the water production rate of the equipment drops and the water in the system is not full, the air needs to be discharged by non-pressure flushing. If the air is not exhausted, the phenomenon of "water hammer" will easily occur and be damaged. After normal operation, observe the production water flow rate, working pressure, conductivity, etc. of the equipment to judge whether the equipment is scaled, and determine the production according to the production water flow rate and concentration degree. Whether the quantity meets the design standard.

2. The pressure difference fluctuation between the inlet port and the concentrated water section

If the pressure between the water inlet of the equipment and the concentrated water fluctuates (such as rising or falling), it is an indication that it is contaminated and needs to be cleaned immediately.

3. Water quality

If the effluent becomes cloudy, apparently due to damage to some component in the unit, it should be investigated immediately. If the scale is not cleaned with chemicals in time, the Graduation of the equipment will increase. serious.

During the daily work of laboratory ultrapure water equipment, the place where the equipment is placed should be ventilated and dry, and it should be repaired regularly to ensure the normal operation of the equipment.
