Nozzle material Hesitate in deciding which nozzle material. Is there any information about material standard? |
|
| |
 |
・ |
To extend nozzle longevity, material is very critical. Please consider wearable, medication-resistant, and heat-resistant material.
Select standard listed below. Furthermore, for special usage, please consult us. |

Planned to equip mini spray nozzle for 2nd cooling of continues foundry machine.Please info us latest movement. |
|
| |
|
・ |
Because of multiplicity of steel sorts and size, high speed foundry, more requirement for
air mist nozzle.
Listed below (Air mist nozzle)
|
|
| |
| |
|
|
Items |
Summary |
|
Lower water air ratio |
Because of less air, lower working costs |
|
Thicker sprayer |
Spray does not touch roller. Increase spray thickness, extend steel board cooling area. |
|
Slow gyration down |
Bases on variety of steel sorts, equal flux distribution even in lower water volume |
|
No blocking |
Strongest requirement in market |
|
Easy for maintenance
|
Time to increase production. Hardly insure personnel and time are available |
|
High wallop |
Destroy steam film by strong spray, promote cooling efficiency |
|
|
| |
| |
|
If informed us your requirements and nozzle model, we will reply as written report.
For each nozzle model, there is a corresponding air mist. |

Steel Industry
Question about carbon removal. |
|
| |
|
・ |
What we thinking about is that, not normal slender nozzle, but large end extension nozzle which makes air speed close to velocity of sound(Vapor nozzle straight type).
Comparing with pipe air spray, wallop increasing germination. Air focusing on a single spot to spray. Make extreme effect to carbon removal.
So as other fields, for example, some outlandish situation. |

Trouble in dryness after washing and air washing.Is there any better air nozzle? |
|
| |
|
・ |
According to different form of a dried thing, nozzle might be different too.
Here is a representative example.As reference while
your company using slit air nozzle. |
|
| |
|
| |
|
| |
| |
|
| Distance to base(mm) |
2～5 |
| Nozzle elevation(°) |
25～30 |
| Nozzle level angle(°) |
15～30 |
| Air pressure (MPa) |
0.05～0.1 |
|
Nozzle slit thickness(mm) |
0.06～0.3 |
|
|
Left sheet
indicates glass base without water drops.
With Variety glass base types and size, the
value differs. Standard for using Slit
air nozzle |

Paper making industry Often use purified water to wash appliance, but always encounter nozzle blocking. Big trouble. |
|
| |
|
| |
| |
|
|
|
Pipe that Impurity can hardly inflow into nozzle (left)Choose nozzle(Type C)is more effective.
In condition of water volume, if choose spray nozzle with certain water amount, makes flux caliber bigger, and hardly blocking.
No need to remove blocking even there is blocking.
Simply lower pressure to 0.03MPa, enlarge nozzle, the blocking shall be removed.

Always use Mist Nozzles to cool exhaust temperature.Hope to reduce dust in cooling tower. |
|
| |
|
・ |
try to use average and maximum particle diameter.(KAMX)
Many cases which the diameter of the maximum particle of the nozzle which carries out atomizing of the adhesion of dust becomes a part for un-evaporating, and generates are seen.
It shows that average particle diameter is very important, but try to restrain the diameter of the maximum particle is necessary. |
|
| |
| |
|
 |
|
More dust caused by nozzle position.
For example, sprayer touches tower wall directly is considerable. If provided nozzle conditions, we may offer position and air restrain report.
Furthermore, spray circle and gas flow may test spray model change. |

Plan to purchase plant dustproof spray nozzle.Need to know information about small particle diameter nozzle. |
|
| |
|
・ |
Firstly, explain how Single-Fluid Nozzle and Mist make particle diameter smaller. |
|
| |
|
| |
| |
|
1) increase working pressure
2) reduce nozzle diameter (reduce spray flux)
Besides above, water bump selection and nozzle blocking are problems too.
For Hydraulic, 17μm is the lowest.
Small particle diameter Single-Fluid Nozzles is Moya nozzle,Hollow-cone nozzle Refer to reference |
|
| |
|
| |
| |
|
Make liquid into particle by using high speed compressed air.
As normal way, widely used in many fields.
So, for plant dustproof, 2-luquid would be better.
For dustproof, Mini mist Nozzle,Pneumatic Atomizing Nozzle PV are suitable.
Minimal particle diameter is 5.3μm (arithmetic average particle diameter) |
