Micro Fire-Extinguishing Aerosol Systems for CNC Machines

CNC masjiene short for “rekenaar numeriese beheer masjiene, are automated milling devices that make industrial components without direct human assistance.

Daar is baie verskillende tipes van CNC masjiene, but the most common ones are milling machines, lathes, and grinders.

Maar, 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 grootte aërosol gebaseerde brandblusapparaat omdat dit in mense se sig kom.

Analysis of Causes

Why do people like the fire extinguishing aerosol system device in CNC machines, ons noem die volgende punte:

• Punt een, 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, gasvrystelling-aanwysers, ens.
• Point three belongs to a new advanced technology that makes it highly effective, skoonmaakmiddel, omgewingsvriendelik, and not have a bad effect on machines and equipment.
• Punt vier, 'n paar ander faktore, 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 om +108 grade 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, dit kan bo-op vasgemaak word, or the side, 'n ander is om magnetiese en 3M-gom te gebruik om dit aan die boonste plafon of kant van die CNC-masjiene te plak.

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 so maklik om te installeer.

Aerosol Basic Specification

Aerosol has the following basic specifications:

• Aerosol fire extinguishing agents are very highly effective.
• Werklike ontwerpdigtheid: nie meer as 100 gram per kubieke meter
• Veiligheidsafstand: 1.5 meter.
• Oplaaityd: binne 30 sekondes
• Brandbestrydingsveiligheidsafstand: 0.3 meter.
• Lewensduur: 10 jaar
• Brandonderdrukkingstipe: A, B, C, E, F
• Tuit temperatuur: nie meer as 200 grade Celsius (5mm afstand vanaf die mondstuk)
• Sal die oppervlak temperatuur: nie meer as 100 grade Celsius.
• Installasie-modus: deur installasiebeugel of deur magneties met 3M-gom
• werkstemperatuur: -40 om +108 grade Celsius.
• werkstemperatuur: ≤95%
• Working Power: DC 3 om 24 volt (of AC3 aan 380 volt).
• Minimum aanvangsstroom: meer as 250 Maar vir 5 millisekondes.
• Maksimum veiligheidsstroom: nie meer as 150 MA per minute.

An Example

Hoe ons aerosolstelsels in 'n CNC-masjienkamer ontwerp, hiermee lys ons 'n voorbeeld hieronder:

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

In die eerste plek, bereken die beskermingsvolume van die masjien, dit is 0,69m * 0,67m * 0,45m en kom tot 0.20 kubieke meter.

In die tweede plek, 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 meter, so the required aerosol device can cover this volume, soos ons aërosol-ontwerpdigtheid is 100 gram per kubieke meter, en ons kleinste model is 30 gram aërosoltoestel, dus Model 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 Sjina, 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 weet ons gerus, ons wil graag vir u ontwerp en diens lewer.

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:

• Voertuie-enjinkamerruimtes.
• Ruimte vir windturbine-enjinkamers
• Vaartuie-enjinkamerruimtes
• ATM spaces
• Elektriese kabinet- en kontrolepaneelruimtes
• Sommige ander klein omhulsels of semi-omhulsels.

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 sal die hele werkswinkel en hul toerusting en vrag selfs in een nag vernietig word.

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, oorweeg dit, dink u nog steeds dat dit nie nodig is om 'n blusapparaat binne 'n CNC-masjien te laat installeer nie? This is a serious question we need to think about.
