Water Purifier Circuit Overload Monitoring Method

Abstract

The invention relates to a water treatment industry and especially relates to drinking water filtration. The invention discloses a water purifier circuit overload monitoring method. The water purifier circuit overload monitoring method utilizes filtration liners and water feeding pipes, wherein fine filtration liners with a booster pump and an electrical control circuit are used or ultraviolet sterilization filtration liners with an ultraviolet lamp and an electrical control circuit are used; the filtration liners are connected in the water feeding pipes in series so that filtration channels are formed; the electrical control circuit is used for controlling operation of the booster pump or the ultraviolet lamp; the water purifier circuit overload monitoring method also utilizes a load monitoring circuit device for setting preset parameters; and the load monitoring circuit device is used for monitoring electrical control circuit-transmitted operating parameters of the booster pump or ultraviolet lamp, carrying out comparison between the operating parameters and related preset parameters, and giving an alarm to prompt a user when the actual operating parameters exceed limiting values, or cutting off the electrical control circuit when the actual operating parameters exceed the limiting values.

Description

technical field [0001] The invention relates to the water treatment industry, and specifically relates to the deep filtration and purification of drinking water. Background technique [0002] At present, water purifiers are relatively popular in China. The water purifier is used to deeply filter the impurities in the water and water pipelines, which better protects the health of users. Yet, along with the popularization of water purifier, their defect and deficiency also gradually exposed in application aspect. After the filter element of the water purifier is used for a period of time, the filter material of the filter element is gradually blocked by impurities and adsorbed on the outer surface of the filter material, resulting in a significant decline in filtration and adsorption effects. The "pollution" degree of the filter element impurities exceeds the "pollution" degree of the drinking water itself, so that the filter element becomes a new "pollution" source. Even i...

AI Technical Summary

Problems solved by technology

As more and more impurities are intercepted by the nanofiltration membrane or reverse osmosis membrane filter element, the load on the booster pump in the water inlet pipeline is also increasing. The tap water fills the water storage container, and the drive circuit of the booster pump is overloaded for longer and longer

The long-term overload operation of the drive circuit of the booster pump will eventually cause the rectifier components to be "burned out", the booster pump will stop running, and the water purifier will have no water supply

There are many reasons why the water purifier does not supply water, such as failure of the lower limit switch of the water storage container, blockage of the pre-filter element, normal blockage of the filter element of the nanofiltration membrane or reverse osmosis membrane, "short circuit" or "open circuit" of other circuits leading to interruption of the power supply circuit, etc.

During the use of the water purifier, it is usually difficult to judge the damage of the electronic control device due to the long-term overload operation of the drive circuit of the booster pump. The outlet water enters the water storage container, and the electric control device is broken again after a short time

Want to replace the expensive nanofiltration membrane or reverse osmosis membrane filter element, but observe that the filter membrane or reverse osmosis membrane filter element has water when the water purifier is running, so it is impossible to confirm whether it should be replaced

In addition, for water purifiers using "ultraviolet filter elements", there is also a similar circuit overload problem: although the life of the ultraviolet lamp of the water purifier is long, it is only suitable for small flow, intermittent, long-term operating environments

For places where there is no need to use ultraviolet light to sterilize and the water consumption is large, the long-term uninterrupted continuous operation of the ultraviolet lamp will cause the radiation intensity of the ultraviolet lamp to attenuate very seriously, and the corresponding service life is far lower than the normal service life, often only a few tens of the normal service life one-third, or even shorter

Moreover, even if the ultraviolet lamp can be lit, its radiation intensity may not meet the radiation intensity requirements, resulting in poor sterilization effect

Above-mentioned defective and deficiency have had a strong impact on the popularization of water purifier product and the raising of quality
