The ultra-pure water mechanism in the laboratory is a relatively common problem. Today, Xiaobian introduces in detail the influencing factors of the ultra-pure water mechanism in the laboratory:
1, PP cotton blockage
This is one of the most common failures. PP cotton is a primary filter element that can effectively remove various particulate impurities in the filtered liquid. The life span is 3-6 months, of course, it is also affected by water consumption and water quality. When the filter element is not replaced for a long time, it will cause blockage, which will affect the amount of water produced.
2, RO membrane blockage
The factors that affect the blockage of RO membrane are as follows:
1) The use of RO membranes has been more than a year or even longer. Water consumption, raw water quality, and RO membrane life are generally proportional.
2), the front filter does not change for a long time, causing the water quality inside the machine to be far worse than the water before entering the machine.
3) The raw water quality is poor, and the proportion of the wastewater is small, which causes the plugging of the waste water solenoid valve or the flushing combined valve, so that no waste water is discharged, or there is very little waste water.
4) The quality of the RO film itself is poor. Therefore, when purchasing RO film, you must purchase the original manufacturer.
5) Sometimes the membrane shell will also cause insufficient water.
3, the pump is small
It usually appears in pure water machines with a service life of more than two years or a pure water machine that has been in working for a long time. As we all know, the core component of the pure water machine has a booster pump, which is responsible for pressurizing the water so that the water can pass through the reverse osmosis membrane. The pump also has a long life. When the water machine is used for a long time, the pump will have a small pressure increase.
The pump loses pressure and is generally not easy to find. His direct performance is that the film has less water or the film does not produce water. It is easy to think that the membrane is blocked.
4, the water inlet solenoid valve malfunction, clogging or
When both pure water and waste water are scarce, after removing the filter plug, it is necessary to change the water inlet solenoid valve to see if it is blocked.
5, low temperature
The water production rate of the RO membrane has a great relationship with the temperature. The hottest does not exceed 45 ° C, the minimum is not less than 5 ° C. At 25 ° C, generally every 1 ° C reduction, the water production will be reduced by 3%. Therefore, the water production rate in winter is generally reduced by half or even more than in summer.
6, check valve blockage
Sometimes the check valve will also be blocked, although this happens very rarely. When checking, you can take the check valve and see the amount of water. If there is a significant change in the amount of water after and after the removal, it means that it is really blocked.
