1-35m, flow 1-5 ton hours；Water pump two and the data of water pump three：Power output 50W, lift 4m, the ton hour of flow 6.5.
4：The parameter of vacuum tank 19 is 50L-0.8MPa, and its pressure gauge position hydraulic pressure is maintained at 0.24 ± 0.02MPa.
5：Environment temperature is maintained at 25 ± 1 DEG C.
Two：Equipment workflow scheme
1：Raw water is configured and checked and accepted
Configuration：555g calcium chloride, the sodium acid carbonate of 537.6g, 100g sodium chloride are successively added to equipped with about 10L pure water
Clean bucket in, often add a kind of solute, stirred to it with glass bar be completely dissolved immediately, then add lower one kind, directly
To whole dissolvings.During the solution that above 10L is prepared is added equipped with about 1990L pure water sealing bucket 2, and electric rotating machine 14 is opened,
Uniform stirring.5.2% 10 milliliters of liquor natrii hypochloritis is taken, 2L is diluted to, is stirring evenly and then adding into above-mentioned sealing bucket 2,
And open electric rotating machine 14 and stir.With sodium hydroxide solution or sulfuric acid solution will seal water pH value in bucket 2 adjust to
Between 7.0-7.5.
Check and accept：After stirring, fetched water 3 times before reverse osmosis water purifier to be measured 5 after pressure gauge 21, the index of water should be as
Under：
A) total hardness should be controlled in (250 ± 20) mg/L；
B) basicity should control (160 ± 20) mg/L；
C) total dissolved solid should be controlled in (500 ± 50) mg/L；
D) pH value should be controlled 7~7.5.
If above index is not in the range of, should continue further to be adjusted with related reagent, make raw water within this range.
2：Test is carried out
Room is closed, and maintain the temperature at 25 DEG C, humidity is maintained at 45%~75%.By reverse osmosis water purifier to be measured 5
Pipeline is accessed, according to after water purifier specification installation and debugging, pump power is opened, variable frequency pump frequency and Flow-rate adjustment is adjusted
The devices such as valve 18, vacuum tank 19, pressure-reducing valve 20 so that water purifier raw water intake pressure is in 0.24 ± 0.02MPa.

Just (the 1st time sampling), 1/4 section of end (the 2nd sampling), 2/4 section of end (the 3rd sampling), 3/4 section of end (the 4th sampling), 4/4 section
When last (the 5th sampling) collection the totally 5 batches of water samples test water purifier go out water purification total hardness (with calcium carbonate) and dissolubility it is total
Solid (TDS).After measuring the total hardness and total dissolved solid fetched water every time, control raw water total hardness and dissolubility are always solid
Body, you can draw the total hardness clearance and total dissolved solid clearance of water purifier.Hardness clearance reaches more than 90%, molten
Solution property total solid clearance reaches more than 85% can think that its removal effect is effective.When hardness or total dissolved solid are removed
When rate is less than its minimum requirements (90%/85%), experiment should be stopped, judging that water purifier purifying water effect is not up to standard.
(2) net water flux measurement：Every time during water intaking, water purifier in 300 seconds should be measured and produce water purification water, calculate its stream
Amount.Water purifier net water flux should be greater than the net water flux of its nameplate sign.If less than nameplate sign, should judge that water purifier does not reach
Mark.
(3) the total water purification amount of water purifier：When water purifier water purification water yield reaches total water purification amount nominal value, total inflow should be recorded
With total concentration water.Water purification producing water ratio is calculated by formula (a) or (b)；If stream can not be met before total water purification amount nominal value is reached
Amount and clearance requirement, then judge that total water purification amount can not reach nominal value, terminates experiment.
In formula：
Y-water purification producing water ratio, %；
Qp-total water purification amount, unit liter (L)；
Qr-always concentrate water, unit liter (L)；
Qf-total inflow, unit liter (L).
Note 1：If water purifier has pre-washing function, washing water quantity should be calculated in total inflow.
Note 2：If water purifier has continuous work defencive function, this function should be shielded.
Note 3：If water purifier is furnished with pressurized tank, pressurized tank should be removed.
Above-described embodiment only to illustrate technology design of the present utility model and feature, technique is familiar with its object is to allow
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover protection domain of the present utility model it
