1. This new machine is specially used for the original chain of digbi. For example, digyi mining has sold this kind of mining machine with good price and service
2. Rated 1800W eth mining machine power supply 24 pin / 6 pin, with 8 independent graphics cards, high power supply
3. It's the feeling of separating him from home and work. I think he doesn't want to have pressure at home when he comes home. Then don't think so much about it. You don't have to do anything for him, on the contrary, it will increase his pressure. Face his time at home with ease. Just be happy.
4. Instrial and mining enterprises,,.
5. I've made some money. I think the risk of investment in ancouli is small. Every day's income will be automatically transferred into my own account. This is much better than other financial management methods.
6. 1、 There are three kinds of driving devices for diesel locomotives:
1, electric drive
DC drive, AC / DC drive and AC / DC (AC) drive. Dongfeng, Dongfeng 2 and Dongfeng 3 locomotives are DC drive locomotives; Electric drive diesel locomotive developed after Dongfeng 4, All of them are AC and DC electric drive locomotives
since 1999, some AC drive locomotives have appeared in succession
the more successful ones are Dongfeng 4dj made in Dalian and Dongfeng 8CJ made in Qishuyan
the domestic electric drive locomotives are all named Dongfeng * type, while the imported ones are nd * type
the most famous ones in China are Dongfeng 11g and Dongfeng 8b made by Qishuyan Locomotive and rolling stock works < br />
2. Hydraulic transmission
General (mechanical reversing) hydraulic transmission and hydraulic transmission with hydraulic reversing; Another is hydraulic mechanical transmission. Beijing type and Dongfanghong series locomotives are hydraulic transmission locomotives; Most GK series instrial and mining locomotives are hydraulic reversing locomotives< The domestic hydraulic transmission is generally Dongfanghong * type and Beijing * type, and the GK series of instrial and mining locomotives are NY * type
the most famous hydraulic transmission locomotive in China is the ND5 type of American General Electric Company
3. Mechanical transmission
should be rare in China; It is rarely used in small power local railways and instrial and mining locomotives.
the main diesel locomotives in China are mainly electric driven Dongfeng locomotives.
now there are fewer hydraulic drive locomotives. However, in the past, the chief special trains were all electric driven internal combustion locomotives driven by ny6 and NY7 of Hansel factory in Germany, Only one Dongfeng 11z locomotive manufactured by Qishuyan Locomotive and rolling stock works is used for traction of special train
the function of transmission device of diesel locomotive
when the fuel supply per cycle is fixed, the torque of diesel engine changes little with the speed; The power of diesel engine is approximately proportional to the speed, and it can reach the rated power only at the rated speed. In order to make full use of the power of diesel engine and realize the requirements of locomotive traction characteristics, diesel locomotive must be equipped with transmission device, which is the intermediate link between diesel engine crankshaft and locomotive moving shaft. The torque, power speed characteristics of diesel engine are converted into the traction characteristics of diesel locomotive: that is, the locomotive has greater traction when starting and low-speed traction; After the train starts, when the handle of the main controller of the locomotive is at a given position, the speed and power of the diesel engine are fixed, and the train running resistance is less than the traction force of the locomotive (the acceleration force is positive), the speed of the locomotive increases along the traction characteristic curve (the traction force decreases accordingly); When the train resistance is greater than the locomotive traction force (the acceleration force is negative), the locomotive speed decreases along the traction characteristic curve (the traction force increases with it); At the same time, through the transmission device to achieve locomotive reversing, power braking and other conditions conversion function, to meet the requirements of train traction.
