2. 1. The high-pressure fault of the air conditioner caused the protection shutdown. The reason may be that the weather is too hot, the radiator of the outdoor unit is dirty and blocked, and the heat can not be dissipated. It is for this reason that the machine can only be started after the power is removed for a few minutes. After the shutdown, the pressure is restored to balance, and the machine cools down, so it can be started. It is recommended to clean the radiator of outdoor unit and spray water with clean water or air conditioner cleaning agent. 2. Fan problem. If the air conditioning compressor and Freon are basically normal when the machine is just started, check whether the speed of the external fan is normal. If the external fan doesn't run or the speed becomes slow, the normal operation of the air conditioner will be affected. The current will increase and the load of the air conditioner will be too heavy.

Ant miner is the first cryptocurrency miner brand in the world with a market share of about 70%. The mining machine is developed by bitmainland and has a patent in mainland China. At the beginning, ant miner had only bitcoin miner. Later, its business expanded to other cryptocurrencies, such as Ethereum, dascoin, Leyte, Monroe, etc

ant mining machine adopts ASIC chip designed by bitcontinental, which is proced by TSMC. All chips are made of BM prefix. Each miner has three to four circuit boards, and there are dozens of chips on the circuit board. Therefore, each miner can only be used to mine one or more cryptocurrencies using the same algorithm

ant mining machine needs special mining software, and can not use third-party software. In addition, because of its high power, the ant miner also needs to be used with a special fire ox

The ant miner is often criticized as monopolizing the cryptocurrency mining instry e to its 70% market share, which goes against the purpose of cryptocurrency decentralization. Because Monroe was worried that the mining machinery would monopolize the mining market, Monroe announced to change the mining algorithm a few days after the launch of Monroe (X3 model) despite the opposition of Monroe community, so that all mining machinery could not be used to mine Monroe. Bitcontinent also encountered the failure of its first proct here

the ant miner will use a lot of electricity and proce a lot of waste heat in the process of operation. This leads to a large amount of electricity being consumed for mining or cooling, causing a lot of social criticism. Too much ant mining machine at the same time also led to fire and power failure, causing social inconvenience

6. 1 whether the power supply provides enough power
2 whether the graphics card overclocking parameters are correct
3 whether the temperature control and cooling are normal

7. In fact, regardless of water cooling, the difference between the price of power supply and the electricity bill comes out. For the same power consumption, ants can arrange three... View the original post & gt& gt;

9. The protective measures are aimed at the problems of the equipment. Yantai Jinpeng mining machinery has been engaged in the proction of mining machinery for many years, and the manufacturing of quarrying machinery has sorted out the protective measures of the quarrying machine and the troubleshooting and simple maintenance methods of the abnormal
1. The main engine vibrates when lifting, and the left and right lifting are not synchronized. The main causes of these faults are as follows:
(1) the fasteners of various transmission parts are loose or damaged
(2) the four columns are changed, which makes the four lifting screws stifle when lifting
(3) the gap between the left and right four sliding seats and the column is not consistent
(4) four bevel gears are damaged
(5)
(6)
2. The following methods should be adopted to check and eliminate the above problems
(1) carefully check whether the pad iron, top screw and fastening bolt under the four columns are loose, and whether the foundation under the column has cracks. If so, timely reinforce and readjust the four columns to make them meet the e standards
(2) carefully check the fastening parts of each transmission part to make it reach the proper fastening state
(3) check the clearance between the sliding seat and the column, and adjust it to the specified range
(4) check the clearance and wear condition between the big and small bevel gears. If there is any damage, replace them in time and adjust the clearance between the big and small bevel gears in time to make them consistent
(5) remove the cover plate on the column and carefully check the wear condition of the four screws. If they are inconsistent, they should be replaced in time or readjusted according to the wear condition of each screw, But in the future proction, we should increase the inspection times of the lead screw and lead screw, and clean the marble particles on the lead screw in time, so as to prevent the occurrence of large mechanical failure and the phenomenon of "locking" of the lead screw
(6) carefully check the fastening of the connecting plate on each transmission part and the connection between the connecting plate and the transmission shaft. If there is looseness, it should be tightened. If there is iron pin or looseness on the transmission shaft, it should be removed in time to check the wear of the key and keyway. If there is wear, it should be replaced in time to avoid greater mechanical failure< 2. Abnormal vibration sound ring cutting
1. Cause analysis of the disease:
(1) excessive bearing clearance; The bearing clearance in the spindle box is too large or seriously damaged; The flange plate is not fastened in place and there are bumps; The main shaft or saw blade support ring is seriously worn and the gear is partially damaged; The fastener at the connection between the spindle box and the gearbox is loose; The large and small V-belts are not statically balanced or loose; When cutting, the knife is too big and the knife is too fast
(2) the cutting head is not sharp, the welding of the cutting head is inconsistent, and there is dislocation
(3) the misalignment error of the inner and outer circles of the matrix is too large, and the center hole of the matrix is too large, which results in the misalignment between the matrix and the main axis, and the outer circle runout is too large; The stone materials are not placed solidly; The pad iron or fastening bolt under the guide rail is loose
2. If the above problems occur, the following methods should be adopted to solve them:
(1). Check the wear condition of the saw blade support ring and the spindle, and repair or replace them if there is any damage
(2) carefully check the clearance of all bearings in the spindle box, especially whether the axial movement of the pinion shaft is too large. Disassemble the gearbox to check the wear condition of the big and small gears. If there is any damage, replace it to prevent damaging the bearing. Reasonably adjust the clearance of each bearing to make the axial movement of the axle reach 0.07-0.10 mm and the radial jump 0.03-0.07 mm, After installing the large V-belt pulley, the runout of the large V-belt pulley shall not exceed 0.30mm. The axial movement of the main shaft shall not exceed 0.10mm. The radial runout of the main shaft shall be 0-0.03mm. After installing the flange, the runout of the outer end face of the flange shall not exceed 0.14mm. After adjustment, the lock nut shall be locked and the washer tooth between the nut and the bearing shall be put into the empty groove of the nut, Rotate the axle by hand to check the operation of each bearing of the headstock, so as to ensure smooth operation without jamming. If there is jam, the bearing is damaged and must be replaced
(3) clean the stone powder on the large and small V-belts to avoid the vibration caused by static imbalance, and adjust the V-belts to the appropriate degree of tightness
(4) check the fastening condition of the inner and outer flange plates, carefully check the use condition of the inner and outer flange plates, carefully clear the burrs, bumps and oil stains, and meet the above standards after installation
(5) cushion the stone and use less sleepers as far as possible
(6) correct the misplaced cutter head by cutting with firebrick, and select the specified feed speed and depth< The main reasons are as follows:
(1)
(2) the bearing clearance on the spindle is too large; The cooling effect is not ideal e to insufficient coolant supply
1) insufficient coolant
2) there is a problem with the coolant supply pump
3) the cooling water pipe on the saw blade shield is blocked
. The quality of the cutter head is not up to the standard, resulting in the diamond particles falling off too fast
(4) the sleeper is used too much and the cushion is not solid
(5) the trolley guide rail is loose
2. To solve the above problems
(1). We must strictly abide by the operating proceres, civilized operation, never for the sake of temporary interests to pursue a "fast" word, otherwise you will pay high maintenance costs
(2) after frequent inspection and maintenance, the symptoms of faults can be eliminated in time
(3) inject water frequently to ensure enough coolant. Frequently clean up the debris in the cooling pool to ensure that the cooling water pipe is unblocked. If there is floating st in the air, stop and check the coolant and cooling water pipe in time to avoid unnecessary loss
(4) try to use hard supports and less sleepers
(5). Always check the fastening of trolley guide rail to avoid unnecessary trouble.
