How to choose the car washer nozzle?

What is a fan nozzle? The more common fan nozzles on the market are just the following four: red is a zero-degree nozzle, yellow is 15 degrees, green is 25 degrees and white is a 40 degree nozzle。

The red and yellow jetheads, which are 0 degrees and 15 degrees, are still of relatively little use, because their impact is too strong, the corresponding flow is smaller, and the efficiency is low and not practical. Therefore, we rarely use a spray head at this angle when we wash our cars.

Occasionally we may need to rinse the ground, especially when stubborn stains require strong pressure, and this small fan with a strong nozzle will be needed.

The most commonly used are a green 25 degree nozzle and a white 40 degree nob.

For example, a 25 degree nozzle is suitable for pre-cleaning, because the impact of near-range cleaning will be greater, and it is easier to rinse off all kinds of dirt on the paint surface.

In contrast, the 40 degree fan is larger, so the foam can be flushed more efficiently when washing.

There's another small shower head, which, as the name suggests, is basically not very powerful.

However, it has a relatively large amount of water - for example, sometimes when we brush the tires, the soap and foam will be much faster, and it will also prevent the droplets from splashing back.

Next, let's give you an example of this more commonly used 40 degree jet.

We see this section has a data. It's written as 040, and it represents a 40 degree fanhead.

Then there's the following 040, which represents a 0.040-inch water vent.

That is, the diameter of the water outlet inside it is 0.040 inches, which translates into 1.236 mm.

Then let's look at the other blowout, which is also 40 degrees. Look at it, which says 40055.

That means he's also a fan blowout at 40 degrees.

But his inner core is 0.055 inches in diameter.

This is 040.

So his fan angle is the same.

But his inner core aperture is one big and one small.

What would this cause?

Let's test them directly and feel their actual grip and strike strength.

It can be obvious that the 40 aperture blowout will be more powerful than the 55 aperture.

It is actually very easy to understand that the smaller the aperture of the nozzle, the greater the force of the water spray.

However, it is not that the smaller or the larger the better, the diameter of the vent must be the most suitable power and flow of the car wash machine.

For example, when this car wash machine came out of the factory, it was standardized with a 40 jet. If we replaced it with a 055 jet, it would obviously have a smaller impact.

But the same requirement is a 40 jet. If we switch to a 30 jet, he will most likely have a truck situation, which is very, very bad for car wash machines.

In simple terms, too small will catch a card, too large will not have a strike force, and the matching required is the most suitable.
