la verdad no se tiene que exagerar, yo lo he dicho y fuerte, con energía y orgullo de ser MEXICANO, pero nunca he llegado a ese límite de exagerar porque se que se ve muy mal
Que tristeza que ya no haya buenos maestros. Este niño tiene habilidades especiales para la declamación, pero necesita a alguien que le explique como utilizar su lenguaje corporal.
@TrainSpotter Leo He must haven't known things... If you have doubts on EMD and GE, ask me, I will answer your queries. - By Jishnukrishna V of Class VIII, Navkis Educational Center, Gokula, Mathikere, Bangaluru (India)
Thats an inverter unit takes 72 volts DC and inverts it to 120 VAC for the compressor to start. Newer ones use R410A, older ones use R22. Probabaly a Carrier. Carrier made several types of units for EMD and GE locomotives and retrofits for earlier models like the GP38.
Vary excellent video and performing self load test. But in the eight notch hariable sound. We protect safety device for ears. Other vice ear drums are damage. Few locomotives of two stroke of E. M. D. Load test I may observed. Now I am retired my service. O. K vary nice. And my best wishes to you.
These engines have an electrical pre-oiler pump to force oil up into the valve-train like aircraft and marine engines would have. You will hear the pre-oiler pump run for about 20-30 seconds if you watch a full cold startup, right before the decompression condensation blow out valve opening and closing procedure. The engine won't even blow out or auto crank up start until the pre-oiler pump has hit engine oil operating pressure of about 90 PSI.
In rail locomotives, which this engine is fitted to, the engines are not pre-lubed unless they are fitted with an electric pump. That's extremely uncommon except on railroads that run their equipment infrequently enough that completely dry starts are a concern. The fuel pump will indeed run for 20 seconds or so, but once the engine lights off the oil pressure guage can be at zero for a maximum of 45 seconds before the mechanical governor shuts the engine down. It's not uncommon to wait around 10-20 seconds for oil pressure to start building at all. This idea that the idea of some oil pressure switch preventing cranking is just something you pulled right out of your as s. No such thing happens in locomotives at all, with the ONLY exception being a soakback pump for turbochargers on engines so equipped. You can blow down without even turning the engine start switch to prime, but it's bad for the injectors. Autostarts also don't run pre-lube on older EMDs as the engine has oil in the block already. Also, oil pressure is generally 20-30 at idle, not 90 you freakin clown. People really oughta read a single sentence of information before they just straight up make shiт up.
Youre right, this loco arrived to our workshop for a complete overhaul., Here photos after rebuilt process: s16.postimg.org/6k1g8n9it/IMG_20160305_WA0000.jpg s16.postimg.org/a4xbrve2d/IMG_20160306_WA0000.jpg
hola amigo buenas mi nombres es yiannis y trabajo en el ferrocarril de antofagasta en chile y la verdad es que nosotros utilizamos estos mismos ventiladores tipo roots que nosotros les llamamos blowers que usan las locomotoras y me causa mucha curiosidad que tipo de prueba le estan haciendo... verificando si los lobulos estan en buenas condiciones o mejor aun el caudal de entrega hacia el motor del blower amigo estoy muy interesado en saber al respecto comunicate conmigo por whatsapp si quieres +56961236438 al mail : yiannis_vs@hotmail.com o al facebook con el nombre de yiannis venizelos solari estoy a la espera de tu respuesta ya que veo que trabajas en un lugar muy parecido al mio que estes muy bien adios!
