Are you caught in the flow error of the water softener?

3M Science Laboratory —— Are you caught in the flow error of water softener?

"Since I washed my face with an artifact, my skin is so slippery."

"Artifact really bad, after taking a shower,

The skin is no longer tight and the hair is smooth. "

"No wonder the clothes in the washing machine recently,

No longer stiff. "

……

?

Yes, these are all 3M artifacts.

The magical feeling.

This artifact is

-3m water softener

?

Soft water can bring many benefits to our life.

So how do I choose?

How about an ideal water softener?

?

Before buying a water softener,

Consumers can first know their water demand,

According to the demand,

Select the water softener product with corresponding flow,

So as to find a suitable water softener model.

Here's a simple way,

Can help you estimate quickly.

Flow demand of domestic water softener—

That is, according to the number of kitchens and bathrooms in the room type.

The 3M Science Laboratory has prepared a photo.

Usually it is a corresponding table for reference.

Knowing the family's demand for soft water flow,

You can start to choose products with corresponding traffic.

Generally speaking,

Flow of water softener

Closely related to the softening resin capacity,

The more softened resin, the greater the flow.

But some people will ask,

After purchasing the water softener,

Some water softeners containing more softening resin were found,

Its sewage flow ratio

The water softener with less softening resin is smaller.

Why is this?

?

Let me answer your question:

This is because the test water pressure is different from the domestic water pressure.

When testing the flow rate of the water softener,

The laboratory has no restrictions on water pressure.

So some products will be based on hotels and factories.

For example, the inlet pressure of commercial buildings,

This kind of water pressure, under the condition of small resin capacity,

You can get a lot of traffic,

And the family's water pressure will be much lower.

Just like a hotel shower,

Large water output and fast water flow,

Some families use the same shower,

It is necessary to install additional pumps.

This leads to a measured flow in the home environment.

Less than the flow measured in the laboratory environment,

But both of them meet the water pressure standard of the test.

?

If consumers believe it,

According to the flow data calculated by commercial inlet pressure,

I bought one that seems to have a lot of traffic.

But a water softener with small resin softening capacity,

It may be because the flow of domestic water equipment is small,

The water pressure is not enough to work.

?

To this end, 3M Company is developing the water softener.

Several schemes have been demonstrated and developed,

It is proved that large flow can be realized in laboratory environment.

But it is not suitable for home environment.

The following are the internal tests of the two schemes.

?

As can be seen from the above table,

R&D scheme a, in the laboratory environment,

When batch flow can be realized, the pressure drop loss is 0.07MPa.

In R&D scheme b, the pressure drop loss is 0.23MPa.

?

Usually,

In order to ensure the family

Normal operation of other water-using equipment,

The allowable peak pressure drop of the water softener is about 0.65438±0 MPa,

Thus, two research and development schemes can be obtained.

The peak flow of home environment after transformation.

?

As can be seen from the above data,

A water softener with large batch flow,

The capacity of that soften resin is not necessarily high,

In a home environment, the peak traffic may be smaller.

* In the internal test of R&D stage, some products mentioned were not listed.

?

Seeing this, everyone will definitely think,

How to be an ordinary consumer?

Practice a pair of golden eyes,

To judge the authenticity of traffic in the home environment?

Actually, it's not difficult,

You can ask the brand two questions:

Question 1,

The flow rate of this water softener,

Is it the flow of home environment?

Question two,

What is the resin capacity of this water softener?

Friends who are not good at math don't have to worry.

You can buy a 3M water softener directly.

After rigorous and responsible research and development,

The flow released by the 3M water softener,

Is the fluidity in the home environment,

Show it to you intuitively, without your time-consuming calculation.

?

* Peak flow: the flow under the condition of continuous operation and pressure difference of 15psi.

* * Water batch flow: experimental data in the approval of water-related products in China.
