Raudteevedurile paigaldatud tulekustutus aerosool

Raudteevedurid on sadade aastate pikkune arenduslugu ja palju aastaid tehnilist uuendust, täna räägime raudteevedurite tulekaitsest, Esiteks, peaksime rääkima raudteevedurite teadmistest.

Raudteevedurite ja veeremi tundmine

Raudteeveduril endal jõuseadet pole, whether it is a passenger locomotive or freight locomotive, we must connect many carriages to form a train, then it can move only after being pulled by a locomotive. Seetõttu, the locomotive is the basic power of railway transportation.

Raudteel kasutatakse mitmesuguseid vedureid, according to the original power of the locomotive, there are Steam locomotives, diesel locomotives, and electric locomotives.

Auruvedur

The application of steam locomotives has a history of more than 170 aastat. It converts the heat energy of a fuel (kivisüsi, õli, puit) into mechanical energy through a steam engine,

It converts the heat energy of a fuel (kivisüsi, õli, puit) into mechanical energy through a steam engine, to make the train move. The steam locomotive is mainly composed of a boiler, auruturbiin, raami, kivisöe veesõiduk, sidur, buffer device, and braking device.

Auruveduril on madal soojustõhusus, large energy consumption, and small transmission capacity, seega on see praegu maailmas järk-järgult kasutuselt kõrvaldatud.

Diiselvedur

A diesel locomotive is a locomotive powered by a diesel engine, its characteristics are high thermal efficiency, pikk pidev tööaeg, sobib kaugsõiduks.

The diesel locomotives currently used can be divided into electric drive and hydraulic drive styles.

• For electric drive, it is driven by the diesel engine to turn mechanical energy into electric energy, veomootori elektrienergia tarnimine, and then transmitting it to the locomotive gear to make the locomotive run.
• Hydraulic drive is equipped with a set of hydraulic transmission devices between the diesel engine and the locomotive driving wheel. The torque output by the diesel engine is transmitted to the locomotive wheelset through the transmission device to make the locomotive produce traction.

Elektriline vedur

Concept and Description of Electric Locomotives

The electric locomotive itself does not carry electric energy, see sõltub elektrienergia saamisest kontaktvõrgu traadist teel, it is driven by a traction motor.

Elektrijaam saadab 110 juurde 220 kv kolmefaasilise toitesagedusega vahelduvvool läbi ülekandeliini raudtee veoalajaama, mis varustab 25 juurde 27.5 kv single-phase power frequency AC power to the catenary for electric locomotives.

An electric locomotive is mainly composed of the vehicle body, veermik, alumine raam, sidur ja puhverseade, braking device, and a complete set of electrical equipment.

The electric locomotive has the advantages of large power, kiire alguskiirus, hea ronida, lihtne rakendada suurel kiirusel ja suurel koormusel.

Hetkel, due to the extensive development of electric power and the continuous development of new energy power, elektrivedur on muutunud kõige laialdasemalt kasutatavaks.

Kiirraudtee, metroo, and light rail we use are all driven by electric locomotives.

Fire Protection Issues and Solutions for Electric Locomotives

Kuid, ükskõik mis tüüpi vedur, sealhulgas elektrivedur, nad toodavad töötamise ajal palju soojust.

Veduril on palju torustikke ja ruum on väga piiratud, Pikaajalise liikumise korral on lihtne termilist põgenemist põhjustada, aging of the line, and high temperature of the weather.

The loss of a locomotive caused by fire after a thermal runaway is huge, ja majanduslik kahju on tuhandeid dollareid. Seetõttu, peame kaaluma vedurite tulekahjude ennetamise küsimust, ja on vaja valida sobiv veduri tuletõrjesüsteem.

Nagu me varem mainisime, there are many locomotive pipes and networks on the expensive railway locomotive and its space is very limited, Seega peavad paigaldatud tulekustutussüsteemil olema järgmised omadused:

• No damage to the locomotive pipeline, parts, or engine compartment.
• Toote maht peaks olema väike, ja see ei võta palju ruumi.
• Süsteemi on lihtne paigaldada ja siluda.
• Tundlik vastus. Once the railway locomotive gets getting thermal runaway, ta peab leegi koheseks summutamiseks tegutsema.

Hetkel, large-scale gas, vaht, and water-mist fire extinguishing systems are not suitable for railway locomotives. ülejäänud kaks toodet on suure tõenäosusega vedurite tulekaitse valik, on: aerosol fire protection või tulejälje toru summutussüsteem.

Võrrelgem siinkohal neid kahte süsteemi: the Aerosol System and the Fire Trace System.

Aerosoolsüsteemi jaoks

The Aerosol system has the following main advantages:

• See on ilma torudeta ja ilma surveta töötada.
• Releasing clean aerosol-forming agent.
• Suurus on väga väike ja kompaktne, normally installed inside the engine compartment of a locomotive.

For the Fire Trace System

Tulekahju jälgimissüsteemil on järgmised peamised eelised:

• It has white or red pipes for transporting fire extinguishing agents.
• It normally works with 1 juurde 5 Mpa rõhk.
• Puhas HFC-22yea või NOVEC vabastamine 1230 (FK 5112) kustutusaine.
• It has a larger size than the aerosol device.
• Üldiselt, its installation position is on the outside of the electrical cabinet or engine compartment.

Seetõttu, considering the above features from the perspective of safety and convenience aerosol fire extinguishing systems will be more suitable for railway locomotives.

Many people worry that they don’t know how to install aerosol systems on railway locomotives it is very simple to install on the railway locomotive. Üldiselt, the aerosol device has its mounting bracket, clamp, and screw, lihtsalt puurige veduri õigesse kohta paar auku (tavaliselt tuleohtlik asend), ja seejärel kinnitage see kinnitusklambritega.

Paigaldamiseks on ka mugavam viis, see on, paigaldada magnetadsorptsiooniga, ja kinnitage tulekustutusseade otse vedurimootori raudplaadi külge.

Juhtmete peal, ühendage tulekustutusseade pehme traadiga veduri akuga, ja seejärel paigaldage laborisse käivitusnupp ja häireseade, Nii lihtne see ongi!

Our dealers around the world have many installation cases, in the following we list some of them:

• Hiina kiirrong.
• Hiina Wuhani raudtee.
• Singapore rail.
• Eurostaari kiirrong.
• Tai kiirrong.
• Bandung High-Speed Rail.
• Lõuna-Aafrika raudtee.

Choosing an aerosol fire suppression system as a railway locomotive fire protection solution is feasible.
