Raudteevedurid on sadade aastate pikkune arenduslugu ja palju aastaid tehnilist uuendust. Täna, we talk about the fire protection of railway locomotives. Esiteks, peaksime rääkima raudteevedurite teadmistest.
Raudteeveduril endal jõuseadet pole, whether it is a passenger locomotive or a freight locomotive; rongi moodustamiseks peame ühendama palju vaguneid, and then it can move only after being pulled by a locomotive. Seetõttu, vedur on raudteetranspordi põhijõud.
There are many kinds of locomotives for the railway. According to the original power of the locomotive, seal on Auruvedurid, diiselvedureid, ja elektrivedurid.
The application of steam locomotives has a 170-year history. See muundab kütuse soojusenergiat (kivisüsi, õli, puit) aurumasina kaudu mehaaniliseks energiaks,
See muundab kütuse soojusenergiat (kivisüsi, õli, puit) aurumasina kaudu mehaaniliseks energiaks, et rong liikuma panna. The components of a steam locomotive are the boiler, the steam turbine, the frame, the coal and water cars, the coupler, the buffers, and the brakes.
The steam locomotives are characterised by low thermal efficiency, high energy consumption, and low conveying capacity, and the people of the world no longer use them.
Diiselvedur on diiselmootoriga vedur, Its characteristics are high thermal efficiency, pikk pidev tööaeg, and suitability for long-distance operation.
The diesel locomotives have two styles: electric drive and hydraulic drive.
Elektrivedur ise elektrienergiat ei kanna, see sõltub elektrienergia saamisest kontaktvõrgu traadist teel. and the traction motor drives the locomotive forward.
Elektrijaam saadab 110 juurde 220 kV three-phase power frequency AC power through the transmission line to the railway traction substation, mis varustab 25 juurde 27.5 kV single-phase power frequency AC power to the catenary for electric locomotives.
An electric locomotive mainly contains the vehicle body, veermik, alumine raam, sidur ja puhverseade, piduriseade, ja täielik elektriseadmete komplekt.
Elektriveduri eelisteks on suur võimsus, kiire alguskiirus, hea ronida, and easy to implement high-speed and heavy-load.
Hetkel, elektrienergia ulatusliku arengu ja uue energiaenergia pideva arengu tõttu, elektrivedur on muutunud kõige laialdasemalt kasutatavaks.
Kiirraudtee, metroo, ja kergraudtee, mida me kasutame, juhivad kõik elektrivedurid.
Kuid, ükskõik mis tüüpi vedur, including an electric locomotive, nad toodavad töötamise ajal palju soojust.
There are many pipeworks on a locomotive, making the internal space limited, which can easily lead to thermal runaway after long periods of travelling, ageing wiring, and hot weather.
Tulekahju põhjustatud veduri kaotus pärast termilist põgenemist on tohutu, 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 is a lot of pipework and limited space, so the fire extinguishing system for locomotives should have the following characteristics:
Hetkel, suuremahuline gaas, vaht, ja vesi-udu tulekustutussüsteemid ei sobi raudteeveduritele. ülejäänud kaks toodet on suure tõenäosusega vedurite tulekaitse valik, on: aerosoolide tulekaitse või tulejälje toru summutussüsteem.
Käesolevaga, let us compare these two systems: the Aerosol Fire Suppression System and the Fire Trace System.
Aerosoolsüsteemil on järgmised peamised eelised:
The fire trace system has the following main advantages:
Seetõttu, from the point of view of safety and convenience, the aerosol fire extinguishing system will be more suitable for railway locomotives.
Many people are worried that they don’t know how to install aerosol systems on railway locomotives. The installation on a railway locomotive is simple. The steps are as follows:
Magnet-attached mounting is a simpler and more convenient way of mounting. We mount the fire extinguishing device directly to the iron plate of the locomotive engine.
The main steps in wiring are as follows
Meie edasimüüjatel üle maailma on palju paigalduskarpe. In the following, we list some of them:
Aerosoolse tulekustutussüsteemi valimine raudteeveduri tuletõrjelahenduseks on teostatav.
