B360 mining motherboard setting

1. Recently, the price of bitcoin has been rising. Last week, the single price of bitcoin broke through the RMB 20000 mark. Compared with speculation, what is more exciting is self-sufficient mining. The assembly of mining machine has become the focus of attention

in order to cater to the current mining boom, major manufacturers have released corresponding mining motherboards to seize the market. What can be inserted into the magic board of 13 graphics cards, super stable power supply and so on. It's easy to ignore the BIOS on the motherboard while configuring the heap. Although the current mining has experienced several years of training, but at present, when we assemble the mining machine, we still need to toss BIOS, in order to use the multi card to improve the performance of mining. For most mine friends, it is a great test to brush BIOS. If the brush is broken, the whole board will be scrapped. The major manufacturers in improving the corresponding configuration at the same time, but rarely invest too much research and development in BIOS. The reason is that the BIOS of mining machinery is difficult to develop, the research and development time is too long, and the cost recovery is slow. Therefore, compared with the BIOS of special mining machine, it is better to improve the profit of motherboard configuration
there are many mining motherboards on the market, but there are few motherboards with BIOS specially set for mining. Recently, Meijie has developed a special intelligent BIOS for the newly upgraded professional mining motherboard sy-b85-btc. The BIOS of this motherboard can intelligently identify 6 graphics cards. Save all mine friends time, plug and play, convenient and fast, mining no longer wait. We all know that AMD's mining graphics cards have been sold crazy recently, and NVIDIA can't sit there any more. It is reported that NVIDIA will launch a professional mine card gtx1060, which has no display output interface. Meijie, with foresight, has set up integrated display output for mining BIOS by default. After that, NVIDIA's gtx1060 can be perfectly adapted, more than enough

Meijie sy-b85-btc is based on the scheme design verified by mining instry for many years, and also continues the characteristics of Meijie's high efficiency and low price mine board. As an ATX board, Meijie is equipped with 7-phase luxury power supply, all solid black gold capacitor and PCI-E stabilized capacitor design, to ensure stable and safe mining< The sy-b85-btc adopts B85 chip design, supports the fourth and fifth generation CPU of lga1150 interface, and supports lga115x and LGA775 radiator. It is convenient for miner to upgrade the motherboard and use the old CPU and radiator at the same time. Of course, six PCI-E slots are essential for the motherboard specially designed for mining. Three of them are pci-ex16 slots and three are pci-ex1 slots, which can support up to 6 cards mining. Meijie sy-b85-btc also supports 7 * 24-hour all-weather mining, lightning protection, over-current protection, over-voltage protection, high temperature protection, etc. Such a sharp artifact, how can you not let mining friends heart?

2. It mainly uses the skill of "seeing and touching". When the power is turned off, check whether the components are connected correctly, whether the capacitance and resistance pins are in good contact, whether the surface of each component is scorched or cracked, and whether the copper foil on each circuit board is burnt out. At the same time, you can touch the surface of some chips with your hand to see if there is a very hot phenomenon

replacement method

when it is uncertain which component is responsible for some fault phenomena, the suspected part can be replaced

3. The unit of bar is about atmospheric pressure, 1 bar = 10 ^ 5 Pascal, 1 (L / min) = 0.001/60 cubic meters per second; In other words,
power = (pressure) × Flow rate / (600 * coefficient)
here, power: kW
pressure: bar
flow rate: L / min
the coefficient is the efficiency, and the surplus considering the load fluctuation and other factors is the driving power.
note that the coefficient in the formula is basically obtained in this way, which can be converted into international units

4. It shows that this kind of pump is
plunger pump
, that is,
when the motor drives
plunger reciprocating motion, the bearable force generated at the top of the plunger is 50kN, which is equivalent to 5T, which is very high.

5.

Calculation formula of head of three cylinder piston pump:

H = P1-P2 + velocity head difference + surface level difference, P1 is the pressure value at outlet, P2 is the pressure value at inlet

for example, the flow rate of a pump is 1t / h

When the outlet is DN25 and the inlet is DN50, H = 1.1 * 102 - (- 0.1 * 102) + velocity head difference + 0.2 = 122.6m, the flow rate of your pump is small, and the velocity head difference can be ignored

the head, flow and power of the pump are important parameters to investigate the performance of the pump

extended data:

power requirements of three cylinder piston pump:

first determine the maximum pressure and the maximum speed required by the actuator of the hydraulic system, calculate the maximum pressure of the system according to the maximum load, and calculate the maximum flow of the system according to the maximum speed, Pressure and flow are multiplied by a factor greater than one, respectively

Then the pressure and flow multiplied by the coefficient are multiplied to get the pump output

Network - Calculation Method of lift of three cylinder piston pump

6. I have made electromagnetic pump, the plunger force is like this: a proction of the coil with magnetic circuit, static state is the spring to push the plunger {that is, the moving iron core} to lengthen the magnetic circuit, in the moment of current magnetic force, strive to shorten the magnetic circuit to pull the plunger back. Alternating current, the spring pushes out the plunger at zero crossing time. This creates a reciprocating motion of the plunger. 2. The general plunger is provided with a valve check valve. You can pump liquid. Three general spring force as a return force, less than the electromagnetic force, so the plunger is attracted to the direction of the movement of the force.

7. Open CATIA software and create a new part file named ball plunger

select YZ plane to enter the sketch and draw a semicircle with diameter of 4; Exit sketch

select the revolver command to rotate to get a sphere

select YZ plane to enter the sketch and draw a contour line; Exit sketch, select revolver and chamfer

select the bottom surface to draw the hexagonal groove

select shape, create surface design and draw helix

create a normal plane with the end point of the helix, return to the part design, draw the thread
add the material, and finish the drawing.

8. When the pump power is fixed, the head is inversely proportional to the flow. That is, the flow is small and the lift is large; The flow is large and the lift is small
the pressure is directly proportional to the head

there is a certain flow rate when the water rises tens of meters from the pump body, which is called the head.

9.

The calculation formula is as follows: η= Q solution / Q management × In the formula of 100%, liquid q is the actual output of oil well (T / D); Q is the theoretical displacement of the pump (T / D)

the injection speed of the machine with the same power can be increased by more than 25%, which is more suitable for the requirements of thin-wall precision injection. Because the power calculation of ordinary PQ system is based on the pressure maintaining state, the power consumption of proportional variable pump system is very low in this action, so the pump displacement can be increased by more than 25%

The heating of the system is reced and the service life of the hydraulic components is prolonged. The proportional variable system has almost no throttling and overflow loss, and the heating of the system is greatly reced. It can not only save the consumption of cooling water, but also greatly improve the service life of sealing elements with low oil temperature

extended data:

piston pump is divided into two representative structural forms of axial piston pump and radial piston pump; As the radial piston pump is a new type of high-efficiency pump with high technology content, with the continuous acceleration of localization, the radial piston pump will inevitably become an important part of the application field of piston pump

The radial piston pump is a kind of piston pump whose reciprocating direction is perpendicular to the driving shaft. Working principle of radial piston pump: the driving torque is transmitted to the star shaped hydraulic cylinder rotor by the driving shaft through the cross coupling, and the stator is not subject to other transverse forces. The rotor is mounted on the port shaft. The radial plunger in the rotor clings to the eccentric stator through the statically balanced slipper
