S11sc mining machine of Xindong Technology

1. At present, the well-known mining machinery manufacturers in the market include bitmainland, Jianan Yun, etc., but now the price of bitcoin has fallen more, and the electricity charge is higher. Mining is not cost-effective. You can directly buy bitcoin as an investment in bitnet exchange.

2. OK. It's not as complicated as you think

4. A9 is still considerable in terms of current revenue. Now it's about 620 yuan a day. Because the income of the first group of miners who used this mining machine to mine is still stable, and the initial income is also 550-650 up and down. The price may not fall, but will rise. Now the currency price is rising steadily, driving the price of mining machinery is also rising. There is also a serious shortage of cash on the market

5. If you dig, now the mining machines are all assembled by yourself, and there is no one specially selling mining machines. Taobao should have, but the performance is very poor, do not recommend directly buy the whole chicken, or recommend you self-assembly.

6.

There is a flat head screw at the bottom of carburetor, which can be unscrewed

carburetor is a key part of engine, small changes may affect vehicle performance. Therefore, in the process of carburetor disassembly, appropriate tools should be used, and the force should be moderate, so as to prevent the deformation of parts. The disassembled parts should be placed in order in order to prevent missing or wrong assembly

in the process of cleaning the carburetor, if more deposits are found in the float chamber of the carburetor, it is often caused by the failure of the gasoline filter. At this time, the gasoline filter should be checked. If the failure is confirmed, the gasoline filter should be cleaned or replaced

extended information:

precautions:

1. Carburetor is a key part of engine, small changes may affect the vehicle performance. Therefore, in the process of carburetor disassembly, appropriate tools should be used, and the force should be moderate, so as to prevent parts from deformation. The disassembled parts should be placed in order in order to prevent missing or wrong assembly

2. The carburetor should be cleaned in a clean place, the outer surface of the carburetor should be cleaned, and the internal parts can be cleaned with special cleaning agent for carburetor or instrial gasoline. In addition to impurities, pay attention to clean the gasoline gum on the surface of parts

3. Clean the cleaned parts with compressed air, and do not wipe them with cloth or paper that may cause burr to prevent re pollution. It is forbidden to poke the blocked small hole with steel wire and other hard objects to prevent the change of carburetor performance caused by changing the aperture. Gasoline or compressed air should be used to wash out

7. R9380x single card computing power 20 is 16.83 per day according to today's 1800
the mining price is a little low these days, and the fluctuation range is very large

8. Now the big end of the mining machine is the core and ants. Each has its own merits. The advantage of ant is that the quality of mining machine is very good and the probability of shutdown is small. Xindong has high computing power, considerable revenue and low purchase cost.

labor distribution rate = labor cost / added value of instrial enterprises
personnel cost rate = labor cost / sales income
average labor cost = labor cost / number of employees
labor cost output coefficient = added value / labor cost
labor cost sales income coefficient = sales income / labor cost
labor cost content = labor cost / total cost
labor cost wage content = labor cost Total capital / labor cost
total labor proctivity = added value of instrial enterprises / number of employees
