Aerosol fire suppression installed on railway locomotive

Spoorweg lokomotiewe het honderde jare se ontwikkelingsgeskiedenis en baie jare van tegniese innovasie, vandag praat ons oor die brandbeskerming van spoorlokomotiewe, Eerstens, ons moet praat oor die kennis van spoorlokomotiewe.

Kennis van spoorlokomotiewe en rollende materieel

Die spoorlokomotief self het geen kragtoestel nie, 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. daarom, the locomotive is the basic power of railway transportation.

Daar is baie soorte lokomotiewe wat op die spoorweg gebruik word, according to the original power of the locomotive, there are Steam locomotives, diesel locomotives, and electric locomotives.

Stoomlokomotief

The application of steam locomotives has a history of more than 170 jaar. It converts the heat energy of a fuel (steenkool, olie, hout) into mechanical energy through a steam engine,

It converts the heat energy of a fuel (steenkool, olie, hout) into mechanical energy through a steam engine, to make the train move. The steam locomotive is mainly composed of a boiler, stoomturbine, raam, steenkoolwatervoertuig, koppelaar, buffer device, and braking device.

Die stoomlokomotief het eienskappe van lae termiese doeltreffendheid, large energy consumption, and small transmission capacity, dus is dit tans in die wêreld uitgefaseer.

Diesellokomotief

A diesel locomotive is a locomotive powered by a diesel engine, its characteristics are high thermal efficiency, lang aaneenlopende werktyd, geskik vir langafstand-operasies.

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, verskaffing van die elektriese energie aan die traksiemotor, 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.

Elektriese lokomotief

Concept and Description of Electric Locomotives

The electric locomotive itself does not carry electric energy, dit hang af van die verkryging van elektriese energie vanaf die kettingdraad langs die pad, it is driven by a traction motor.

Die kragsentrale stuur 110 om 220 kv driefase-kragfrekwensie WS-krag deur die transmissielyn na die spoorweg-traksie substasie, wat verskaf 25 om 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, hardloopuitrusting, onder-raam, koppelaar en buffer toestel, braking device, and a complete set of electrical equipment.

The electric locomotive has the advantages of large power, vinnige beginspoed, goed met klim, maklik om hoëspoed en swaar vrag te implementeer.

Huidiglik, due to the extensive development of electric power and the continuous development of new energy power, die elektriese lokomotief het die mees gebruikte geword.

Die hoëspoed spoor, metro, and light rail we use are all driven by electric locomotives.

Fire Protection Issues and Solutions for Electric Locomotives

Maar, maak nie saak watter tipe lokomotief nie, insluitend elektriese lokomotief, hulle sal baie hitte produseer wanneer hulle werk.

Daar is baie pypleidings op die lokomotief en die spasie is baie beperk, dit is maklik om termiese weghol te veroorsaak onder die toestand van lang tyd beweeg, aging of the line, and high temperature of the weather.

The loss of a locomotive caused by fire after a thermal runaway is huge, en die ekonomiese verlies is duisende dollars. daarom, ons moet die kwessie van lokomotiefbrandvoorkoming oorweeg, en dit is nodig om 'n geskikte lokomotiefbrandbeskermingstelsel te kies.

Soos ons vroeër genoem het, there are many locomotive pipes and networks on the expensive railway locomotive and its space is very limited, Die brandonderdrukkingstelsel wat geïnstalleer is, moet dus die volgende kenmerke hê:

• No damage to the locomotive pipeline, parts, or engine compartment.
• Die volume van die produk moet klein wees, en dit sal nie baie spasie in beslag neem nie.
• Maklik om die stelsel te installeer en te ontfout.
• Sensitiewe reaksie. Once the railway locomotive gets getting thermal runaway, dit moet aksie neem om die vlam onmiddellik te onderdruk.

Huidiglik, large-scale gas, skuim, and water-mist fire extinguishing systems are not suitable for railway locomotives. die oorblywende twee produkte sal heel waarskynlik die keuse van lokomotiefbrandbeskerming wees, is: aerosol fire protection of brandspoorbuisonderdrukkingstelsel.

Laat ons hiermee hierdie twee stelsels vergelyk: the Aerosol System and the Fire Trace System.

Vir Aerosol System

The Aerosol system has the following main advantages:

• Dit is pyploos en sonder druk om te werk.
• Releasing clean aerosol-forming agent.
• Grootte is baie klein en kompak, normally installed inside the engine compartment of a locomotive.

For the Fire Trace System

Brandspoorstelsel het die volgende hoofvoordele:

• It has white or red pipes for transporting fire extinguishing agents.
• It normally works with 1 om 5 Mpa druk.
• Maak skoon HFC-22yea of ​​NOVEC vry 1230 (FK 5112) blusmiddel.
• It has a larger size than the aerosol device.
• In general, its installation position is on the outside of the electrical cabinet or engine compartment.

daarom, 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. Oor die algemeen, the aerosol device has its mounting bracket, clamp, and screw, boor net 'n paar gate op die regte posisie op die lokomotief (gewoonlik die posisie wat geneig is tot vuur), en maak dit dan vas met die monteerhakies.

Daar is ook 'n geriefliker manier om te installeer, dit is, om te installeer deur magneetadsorpsie, en maak die brandblustoestel direk aan die ysterplaat van die lokomotiefenjin vas.

Op die bedrading, koppel die brandblustoestel met 'n sagte draad aan die battery op die lokomotief, en installeer dan 'n beginknoppie en 'n alarmtoestel in die laboratorium, Dit is so eenvoudig!

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

• China hoëspoed trein.
• Wuhan-spoor van China.
• Singapore rail.
• Euro-ster hoëspoed trein.
• Thailand hoëspoed trein.
• Bandung High-Speed Rail.
• Suid-Afrika Spoorweg.

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