is an incredible display of power and ingenuity. It combines some great mechanical technology, including a huge, 12-cylinder, two-stroke diesel engine, with some heavy duty electric motors and generators, throwing in a little bit of computer technology for good measure.This دیدن لینک ها برای شما امکان پذیر نیست. لطفا ثبت نام کنید یا وارد حساب خود شوید تا بتوانید لینک ها را ببینید.
is designed to tow passenger-train cars at speeds of up to 110 miles per hour (177 kph). The diesel engine makes 3,200 horsepower, and the generator can turn this into almost 4,700 amps of electrical current. The four drive motors use this electricity to generate over 64,000 pounds of thrust. There is a completely separate V-12 engine and generator to provide electrical power for the rest of the train. This generator is called the head-end power unit. The one on this train can make over 560 kilowatts (kW) of electrical power.This combination of diesel engine and electric generators and motors makes the locomotive a hybrid vehicle. In this article, we'll start by learning why locomotives are built this way and why they have steel wheels. Then we'll take a look at the layout and key components.The main reason why دیدن لینک ها برای شما امکان پذیر نیست. لطفا ثبت نام کنید یا وارد حساب خود شوید تا بتوانید لینک ها را ببینید.
s are hybrid is that this eliminates the need for mechanical transmission, as found in cars. Let's start by understanding why cars have transmissions.

, regardless of its location or product application. There are idlers, winches, bearings, couplings, gearboxes, motors, fluid couplings, and scrapers — not to mention the structure as well.Conventional conveyor belts are comprised of three layers.There is the top layer, or cover, which is what the product rests on during transportation. The middle layer is also known as the carcass, which helps support the belt. The carcass tends to be made of either metal or woven fabric. Then, there’s the bottom cover to complete the belt makeup.Today, دیدن لینک ها برای شما امکان پذیر نیست. لطفا ثبت نام کنید یا وارد حساب خود شوید تا بتوانید لینک ها را ببینید.

is mainly used in mining areas above coal mines or metal mines, because after scraping the soft slag to the ideal location, for example, our ideal location distance in the mining area is 30-100 meters, which is not very convenient or safe for labor. . Then we can use a slag scraper instead of manually fetching the slag to the ideal position for raking and loading the slag. According to the principle of the winch, the scraper uses a wire rope to drive the scraper bucket to remove the slag, pull it back to the ideal position from a certain distance, and send it back to the coal mining face for a new round of slag removal, which is convenient and quick.
