Analysis of several key factors affecting the water production speed of laboratory pure water system

      The laboratory pure water system has a simple and clear structure, high pressure and no leakage, and low investment cost. It is widely used in hospitals, scientific research institutes, testing departments, physical and chemical laboratories, etc. After the system is used for a period of time, the water production gradually becomes slower, and it can not even meet the daily water demand. Slow water production in this system is a relatively common problem. So what are the specific reasons, let's take a closer look.

1. Blockage problem

(1) Activated carbon blockage

Activated carbon filters are generally prone to blockage after one year of use. If the raw water quality is not good, or the pre-filter is not replaced for a long time, it will also cause blockage.

(2) The check valve is blocked

It is rare for the check valve to be blocked. During the inspection, the check valve can be removed, and observe whether the change of water output before and after removal is obvious. If the change is obvious, it means that the check valve is blocked.

(3) PP cotton is blocked

The life of the PP cotton filter element is about 6 months, and the specific use time is also affected by the amount of water produced and the local water quality. Many users ignore the importance and necessity of replacing the filter element, and the clogging of PP cotton has become one of the more common faults. It is recommended that you equip the ultrapure water machine with pretreatment equipment to filter larger particles of impurities. Youpu ultrapure water machine can monitor the replacement cycle of consumables through flow and display replacement information.

(4) The water inlet solenoid valve is blocked or malfunctioning

If the amount of pure water and concentrated waste water is small, after eliminating the clogging factor of the filter element, you can check whether the solenoid valve is blocked.

2. Stress problems

(1) The pump loses pressure

Some users found that the water production was slow after using the system for a long time, and they thought that the membrane was blocked and contacted us to replace the membrane. But the water situation has not improved. Opok's after-sales engineers rushed to the scene and judged that there was a problem with the pump based on years of experience. After inspection, it was found that the output pressure of the pump was only 2KG. After the pump was replaced, water production returned to normal. Pump depressurization is often not noticeable. When everyone sees the drop in water production, they take it for granted that the membrane is blocked. Pump pressure loss generally occurs in pure water machines that have been used for more than 2 years or have been in a fatigued working state for a long time.

(2) The transformer is faulty

If there is no problem with the pump itself when the pump loses pressure, check whether the transformer is faulty. Transformer faults are generally less obvious, as the transformer is often not directly broken, but can also provide a smaller voltage. At this time, the voltage required for the normal boosting of the pump cannot be supplied. If the boost pressure is small, the water production will be slow.

3. Other reasons

(1) Human factors

Many pure water equipment will be equipped with water buckets. If the installer is negligent during installation and does not turn on the switch of the water storage tank, it will cause the water outlet to flow slowly, making people mistakenly think that the water production of the equipment has slowed down.

(2) Product factors

The quality of the membrane itself is poor and easy to block. Or there is a problem with the membrane casing, and the membrane casing can be replaced. Here we recommend that you buy products from better manufacturers.

(3) Environmental factors

The operating temperature of the system is between 5 and 40°C. If the temperature is too low, the water temperature will drop, the water flow will slow down, and the water production will be affected. Taking 20°C as the standard, the water production will decrease by 3% for every 1°C decrease in the general ambient temperature. In this case, don't worry too much, it will return to normal when the weather warms up.

The above are the key factors that affect the water production speed of the laboratory pure water system. Users can only deal with the problem in time if they understand several key factors that cause this problem.
