Micro Fire-Extinguishing Aerosol Systems for CNC Machines

CNC-machines short for “computer numerieke besturingsmachines, are automated milling devices that make industrial components without direct human assistance.

Er zijn veel verschillende soorten CNC-machines, but the most common ones are milling machines, lathes, and grinders.

echter, the CNC machines are not only very expensive for each device, but also work every 7/24 hours in operation very easy to get a fire and the fire destroys them.
So that the workshop owners are always suffering from a great loss.

Now not only in China but also all over the world showing interest in installing a small size and highly effective fire suppression device inside the CNC machines, een soort klein op aerosol gebaseerd brandblusapparaat omdat het in het zicht van mensen komt.

Analysis of Causes

Why do people like the fire extinguishing aerosol system device in CNC machines, we zetten de volgende punten op een rij::

• Punt één, We can make the aerosol fire suppression devices in very small sizes, and not take up much space in the CNC machines.
• Punt twee, it is a standalone system with fire detection and fire suppression functions, not required to work with any other fire alarm systems like fire control panel, rookmelder, hitte detector, gasvrijgave-indicatoren, enzovoort.
• Point three belongs to a new advanced technology that makes it highly effective, schoon middel, milieuvriendelijk, and not have a bad effect on machines and equipment.
• Punt vier, enkele andere factoren, like other gas suppression systems, are very complex and very large.

Feasibility Description of Aerosol Application in CNC Machines

In practice and after many actual tests it proven that the aerosol fire extinguishing system and its device are very suitable for installation in CNC machines.

Inside a CNC machine space, the temperature is always a bit high, and the working temperature of an aerosol fire extinguishing device is normally from -40 tot +108 graden Celsius, so an aerosol system is very suitable to install in a CNC machine space.

An Aerosol system is good to install in CNC machines, one method is to use an installation bracket and its screws to fix the aerosol inside the CNC machine space, het kan aan de bovenkant worden bevestigd, or the side, een andere is om magnetische en 3M-lijm te gebruiken om het aan het bovenste plafond of de zijkant van de CNC-machines te hechten.

The Aerosol system works to flood the whole CNC machine spaces to suppress the fire, it runs out of the fog-alike aerosol compound and quickly reaches everywhere in the CNC machine spaces to extinguish the fire.

We kindly recommend thermal cord activation of the aerosol fire extinguishing device of thermo bulb activation of the aerosol fire suppression generator inside the CNC machine because using them does not require any fire alarm system to work with, en zo eenvoudig te installeren.

Aerosol Basic Specification

Aerosol has the following basic specifications:

• Aerosol fire extinguishing agents are very highly effective.
• Werkelijke ontwerpdichtheid: niet meer dan 100 gram per kubieke meter
• Veiligheidsafstand: 1.5 meter.
• Ontlaadtijd:: binnen 30 seconden
• Brandbestrijding veiligheidsafstand: 0.3 meter.
• Levensduur: 10 jaar
• Type brandbestrijding:: EEN, B, C, E, F
• Uitlooptemperatuur: niet meer dan 200 graden Celsius (5mm afstand van het mondstuk)
• Zal oppervlaktetemperatuur: niet meer dan 100 graden Celsius.
• Installatiemodus:: door installatiebeugel of door magnetisch met 3M-lijm
• Werktemperatuur: -40 tot +108 graden Celsius.
• Werktemperatuur: ≤95%
• Werkkracht: gelijkstroom 3 tot 24 volt (of AC3 naar 380 volt).
• Minimale startstroom: meer dan 250 Maar voor 5 milliseconden.
• Maximale veiligheidsstroom: niet meer dan 150 MA per minute.

An Example

Hoe we brandblus-aërosolsystemen ontwerpen in een CNC-machinekamer, hierbij geven we hieronder een voorbeeld::

A compact center-less style internal grinder with a size of 690 mm lang, 670 mm in width, en 450 mm in height requires to design of a small fixed aerosol fire extinguishing device to protect.

ten eerste, bereken het beschermingsvolume van de machine, het is 0,69 m * 0,67 m * 0,45 m en komt op: 0.20 Kubieke meters.

ten tweede, to choose which quantity of aerosol and which model to install in this machine, we have already calculated out the protection volume is 0.2 Kubieke meters, so the required aerosol device can cover this volume, zoals onze aërosolontwerpdichtheid is: 100 gram per kubieke meter, en ons kleinste model is 30 gram aerosolapparaat, dus modelnummer AW-QH-30TH(of AW-QH-30ST) is needed to design and install in this grinder machine.

So you can see only a small capacity of the aerosol device can be installed inside the expensive grinder machine, so it is cost-effective and workable.

In China, we have installed many aerosol devices inside the CNC machines for many manufacturer companies and small workshops, and also in the overseas market we have many cases if readers of this article have some similar project which will require a fire suppression system to cover the CNC machines, laat het ons dan gerust weten, we willen graag voor u ontwerpen en servicen!.

More Applications for Fire-Extinguishing Aerosol Systems

Aerosol devices not only be able to installed in CNC machines but also can be able to used in some of the following similar spaces:

• Ruimtes in de machinekamer van voertuigen.
• Ruimten in de machinekamer van windturbines
• Ruimten in de machinekamer van het schip
• ATM spaces
• Ruimten voor schakelkasten en bedieningspaneel
• Enkele andere kleine behuizingen of semi-behuizingen.

Conclusion and feedback

Some people do not like to install a small fire suppression device inside the CNC machine the reason is that the machines seldom catch fire or there is zero possibility of catching fire, in their real operation it is true seldom a fire in a CNC machine, but once a CNC gets a fire, dan wordt de hele werkplaats en hun uitrusting en lading zelfs in één nacht vernietigd.

In China in our city there is a block company that produces bus energy that caught fire in one workshop and caused a loss of USD1500000, the cause of the fire is that one milling machine operated for a long time and melted the electrical cable to catch fire, dus denk hier eens over na, denk je nog steeds dat het niet nodig is om een ​​brandblusapparaat in een CNC-machine te installeren?? This is a serious question we need to think about.
