How to use two power sources for mining machine
all oil holes on the machine and all rotating parts should be refueled with clean sewing machine oil every 4 hours. Other oils and unclean sewing machine oil should not be used, so as not to affect the service life of the machine
(2) regular maintenance and inspection
it is necessary to keep the parts clean, regularly check whether the temperature and sound of the rotating parts are normal, and repair them immediately if any problems are found, so as to avoid damaging the machine
generally, minor overhaul is concted once a month, and cleaning and major overhaul are concted once a half year. After being put into use for a long time, it should be cleaned and overhauled first
the thickness and use speed of the sewing material should be selected within the specified range, and it should not be overloaded or over speed.
1. Open the iron box of the power supply, take out the circuit board from the box, and use a brush to remove the st
2. Find the key components. Including: power oscillation integrated block, optocoupler, 12V voltage regulator, pulse width adjusting potentiometer, etc. Find the information of power supply mole
3. First, change the 12V voltage regulator into 15V, and find the pulse width adjustment circuit according to the data of power supply integrated block. Some power supplies do not design power supply fine-tuning, but fixed resistance. Remove the fixed resistance, and connect a potentiometer whose resistance value is basically close to the welding resistance on the two solder joints. Now adjust the resistance of the potentiometer to the maximum
4. Use a multimeter to monitor the 12 V power supply port, turn on the power supply, slowly rece the resistance of the potentiometer, observe the voltage change, and adjust it to 15 v. After stabilization, observe for a little time and connect the false load toaster
5. After it is accurate, measure the resistance of the potentiometer and replace it with a fixed resistance with the same resistance.
The PFC circuit has at least boost inctor, field effect transistor and rectifier diode. Please refer to the above drawing< br />
however, an unstable power supply can not directly supply power to the load, so it must be stabilized first (energy storage, inverter, etc.)
power supply switching is very simple, with al power automatic switch, switching time is only a few milliseconds, which will not cause power interruption. You can also set a power priority
if al power supply is needed at the same time, it needs to be connected to the grid
it is simpler to switch the DC side of al power supply than the AC side.
1. Create a new archive (must be in the state of Networking), in this we suggest you build an internal line, simple and crude
2. According to the plot, after graating from high school, pig's feet will participate in the University League, a total of 5 games
before you start playing, please press your key 3 to set the difficulty of the game to [rookie] difficulty
the first game: Civil War
the second game: big a and big B PK
the third game: big a and big C pK (but this one has a lot of media attention)
the fourth game: University League semi-final
the fifth game: University League final (if you lose the semi-final, you still want to play the final?)
what can you row on the Internet? This is similar. I suggest you try not to row because it will affect your draft ranking. In other words, it will directly affect your playing time in the first few games after you enter the NBA
since it's a VC brush, I don't want to spend money or energy, so I can only send one sentence: why don't you go to heaven
please be a brush B as much as possible when playing in the University League, which is actually a brush B
the more adverse the data, the better! After that, we will receive coach k's invitation from the national team. I don't have a specific study on the impact of this game, but I don't think the impact should be too big. After playing the national team, it will be the draft
by convention, at least it's a lotto show, right? No matter which team is selected, before entering rookie season! Please do not forget to adjust the length of the game: 12 minutes, not long enough, do you want to brush VC
3. In the rookie's difficulty, you will be substituted for about 10-15 minutes in a 12 minute game
please cherish every minute you go on the court, cut points, brush assists, brush rebounds as much as possible! Generally speaking, a double double is no problem, scoring about 50 +, assists about 6-8, rebounds about 15, after the first game, if you can get this data, then your VC number can basically guarantee about 100000, if you can't get this data, then please play again, brush up your average data
4. Simulation ends the whole rookie season (select the second day of the last game day of your rookie season, click the pass key, there will be a dialog box, select "simulation ends the regular season"). After that, we will find that we have won the regular MVP, best rookie, best sixth person and other awards
5. Playoffs, it's more troublesome, Every playoff game needs us to get into the game screen! After entering the game screen, both sides can simulate the end of the circle jump. In this way, generally speaking, the most is to enter the second round of the playoffs and then be eliminated
6. After the elimination of the playoffs, we become free agents and randomly choose a team with relatively more playing time, which doesn't have much influence.
7. The second season begins, which is also the real start of our VC brush! On the first day of the second season, please open your SMS. You'll see a lot of news from agents and stars. Here's the key! Only look at the agent and mother's news, other people's news will be ignored
8. After reading the broker's news, open your own contract page and choose one with more activities to sign a contract.
9. Here I need to explain in detail that after signing a contract, business activities are the main source of our VC
-
open source big data ecosystem
-
Hadoop HDFS, Hadoop maprec, HBase, hive are graally born, and the early Hadoop ecosystem is graally formed
-
the open source ecosystem is active, but Hadoop has high technical requirements and poor real-time performance
