What is an air nozzle?

Know the type of air nozzle first.

According to the atomization principle of the air nozzle, it can be roughly divided into 3 different types.

1. Liquid pressurized nozzles (single-fluid air nozzles) only use a pump to pressurize the liquid to the required pressure, that is called a liquid pressurized air nozzle. This type of air nozzle has a coarser average spray particle size and the smallest spray The minimum size is about 50μm

2. Gas-assisted nozzles (two-fluid air nozzles) use high-pressure gas as power to assist the micro-atomization of liquids, that is called air-assisted nozzles, and the liquid supply methods of such nozzles can be divided into two types: pressure type and siphon type. Fine, the smallest can reach 10~20μm (Micron).

3. The ultrasonic air nozzle is a titanium alloy ultrasonic generator installed at the nozzle tip of the air-assisted nozzle. When the atomized droplets hit the titanium alloy ultrasonic generator at high speed, sound waves are generated immediately, and the spray particle size Therefore, it will be more micro-atomized, and the average spray particle size can reach below 10μm (Micron).

What is the spray angle?

When the spiral air nozzle is spraying, the angle that is closest to the spray angle on both sides is called "spray angle". The size of the relationship between the spray angle and the spray height (the distance from the nozzle mouth to the sprayed object).

What is the air nozzles spray particle size?

The average particle size of spray droplets is called "spray particle size". The spray particle size is related to the contact probability, penetration rate and evaporation time of the spray droplet and the sprayed object.

How to distinguish the flow distribution of spray?

In most cases where air nozzles are used, several nozzles need to be arranged together. In order to achieve the same uniformity after multiple arrangements, our R&D engineers design the distribution characteristics for the nozzles. The flow distribution measurement method, simply put, is to arrange a whole row of test tubes under the nozzle in the spray, and the droplets ejected from the nozzle are completely received by a test tube. The amount of liquid received is different, so from The flow distribution can be seen from the side view.

1. Air nozzles standard convex distribution

The flow distribution is in the form of many in the middle, and the two sides gradually decrease. When the plural numbers are arranged, they must overlap by 50%, so that when the plural numbers are arranged, the flow distribution reaches the complete

2. Air nozzles convex equal distribution complex number permutation

Equal distribution The flow distribution is almost completely uniform, and only 10% overlap is required when the complex arrangement is completed, so that when the complex arrangement is completed, the flow distribution is completely uniform

3. Air nozzles equally distributed complex number permutation

Concave distribution The flow distribution shows the distribution pattern of the middle concave, which is the unique flow distribution pattern of hollow conical nozzles

4. Air nozzles single point distribution

This is the unique flow distribution method of linear nozzles

Impact of air nozzles

The pressure on the unit area of the surface of the object being sprayed is called the impact force. Under the same operating conditions, the impact force is compared, and the results are as follows: Linear > Sector > Hollow Cone > Solid Cone and Square Cone

Rotation angle of air nozzle

When a complex arrangement is performed, because of its strong impact force, it must be rotated 12°~15° in the same direction to avoid mutual interference between the nozzles, which will affect the spray quality and nozzle effect.

What about the air nozzles at the bottom of the jacuzzi?

High water volume mute adjustable nozzle, 3/8" nozzle, at 18psi (Pascals), with the air switch fully open, the air nozzle output is 14gpm (refill/min). This nozzle can produce about 10,000 Small air bubbles, small air bubbles are not easy to float to the water surface quickly and burst, so the water flow from the nozzle is strong but very soft. The air nozzle massages the size of the water, and the air nozzle can be opened from the front to clean the inside of the nozzle. Double Spiral massage air nozzle, unique swirling bubbles and continuous vortex action create a consistent rotation of air and water flow.

Delivers a deep massage force that effectively relaxes tense muscles and relieves stress. The bubble massage system uses the bubble pump through the bubble air nozzles at the bottom of the bathtub to generate a large amount of bubbles to wrap the whole body and gently touch the body, that can make the spine and neck feel comfortable, so that the muscles and body and mind can be relaxed.

Many Jacuzzis on the market have air nozzles at the bottom, but don't actually function as a bubble massage

The reason is:

(1) If the bubble pump is not installed, there is no bubble massage function.

(2) The air nozzles at the bottom is connected to the water pump, and the spray is water, that cannot relax the body. Moreover, because the pipes connecting the nozzle at the bottom and the water pump are lower than the suction port, the accumulated water in these pipes cannot be discharged at all.

Matching nozzle:

1. Heavy duty aerosol air nozzle, using compressed air, nitrogen, steam to atomize liquid.

2. Lightweight aerosol air nozzle, using compressed air

3. Single fluid fine atomizing air nozzle.
