Description
Technical field
The present invention relates to a kind of life detecting method and device of purified water filter core, in particular, more particularly to it is a kind of
The life detecting method of the purified water filter core of life-span judgement is carried out by judging the pressure between filter core water inlet end and water side
And device.
Background technology
The water quality of drinking water, directly affects the healthy of the crowd of drinking, it is ensured that the safety of drinking water is basic place.
However, developing rapidly with social economy, while bringing abundant material, also result in serious environmental pollution,
Wherein water pollution is especially prominent.Waste water, waste residue, the waste gas of plant emissions not only directly pollute rainwash, but also permeate
To underground, pollution is caused to underground water.Therefore, in order to ensure the security of drinking water, it will usually in tap water pipe network
Water is purified again, to ensure the safety of drinking water.
In the purification process of drinking water, the fine impurity in water quality, heavy metal etc. are filtered out by filter core, reached net
Change the purpose of water quality.A set of water purification system, although purification of water quality is completed using multi-stage filter core, but the life-span of each filter core is
It is regular.In service life, filter core can play filtration well；Useful life, then filter if more than
The filter capacity reduction of core, cause detergent power decline or can not filtering water, therefore the life tests of filter core are particularly important.
About the detection of filter element life, typically now using periodic replacement filter core, or according to total purification water come
Change filter core.However, influenceed by water quality is different, when identical filter core is purified to different quality, its service life be it is different, it is single
It is pure by periodically or fixed purification water weighs filter element life, be inaccurate, do not meet it is actual.
The content of the invention
The present invention in order to overcome the shortcoming of above-mentioned technical problem there is provided a kind of life detecting method of purified water filter core and
Device.
