The battery of the sewer truck is used by the vehicle to start the engine and provide additional power to the engine, lights, and accessories. Sometimes it also supplies power to the car's electronic system. Sewage vehicles need to consider many factors when replacing batteries, but the principle of Xiaobian is to believe in reputable manufacturers and brands. Of course, there are many principles that need attention when choosing a battery.
When selecting the model of the sewer truck battery, be sure to select the appropriate model. If you choose a large model will cause the battery to charge less fully. Choosing a small one will result in half of the time when you use it, and you may not even start the car. When choosing a battery, pay attention to the quality of the battery, whether it passes the certification of some quality systems, and whether the manufacturers have perfect after-sales services, such as the national service hotline and service network, so that we can worry about when we encounter problems.
Here Xiao Bian has to mention two types of batteries, one is a maintenance-free battery and a maintenance battery. Maintenance-free batteries usually have a longer operating life, faster charging, and longer shelf life, but they are more prone to problems due to falling off of the moving disk material. The maintenance battery is more suitable for vehicles that are used in hot climates. Because the battery is not sealed, battery water can be added when needed.
When buying enough batteries, pay attention:
1, look at the shell. More refined, no burrs, and meshed skeletons on both sides of the battery.
2, see column. The ones that have scratches are used. This is a direct way to judge whether reviews have been used.
3. The weight of the battery basically represents the content of lead. The higher the lead content of the battery is, the higher the price of the battery is determined by the content of lead. The value of lead accounts for 70% of the value of the entire battery. In the same model, if the heavier weight indicates that the lead content is relatively high, the battery life will be relatively long.
4, different types of batteries, the voltage is the same, the storage capacity is not the same. In the case of the same load, the output current is the same, but the duration of continuous discharge is not the same, and the difference of about 10% in capacity has no effect on the use of the vehicle and the headlights.

A mining machine is a computer used to earn bitcoins. This type of computer generally has professional mining chips, and most of them work by burning graphics cards, which consume a lot of power. The user downloads the software with a personal computer and then runs a specific algorithm, and communicates with a remote server to obtain corresponding bitcoins, which is one of the ways to obtain bitcoins.
Mining machine is one of the ways to get it. (Bitcoin) is a network virtual currency generated by open source P2P software. It does not rely on the issuance of a specific currency institution, and is generated through a large number of calculations of a specific algorithm. The economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transaction behaviors. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be artificially manipulated through mass production.
Any computer can become a mining machine, but the benefit will be relatively low, and it may not be possible to mine one in ten years. Many companies have developed professional mining machines. This kind of mining machine equipped with special mining chips is dozens or hundreds of times higher than ordinary computers.
The graphics card (Video card, Display card, Graphics card, Video adapter) is one of the basic components of a personal computer. It converts the display information required by the computer system to drive the display, and provides progressive or interlaced scanning signals to the display to control the display. Correct display is an important component that connects the monitor and the motherboard of the personal computer, and is one of the important devices of "man-machine". Its built-in parallel computing capability is also used for deep learning and other calculations at this stage.
It is generally divided into three types: integrated graphics card, discrete graphics card, and core graphics card. As an important part of the computer host, the graphics card is a device for digital-to-analog signal conversion by the computer, and it undertakes the task of outputting display graphics.
The graphics card is connected to the computer motherboard, which converts the digital signal of the computer into an analog signal for display on the monitor. At the same time, the graphics card still has image processing capabilities, which can assist the CPU to work and improve the overall operating speed.
The current top500 computers all include graphics card computing cores. In scientific computing, a graphics card is called a display accelerator card.
Video memory is the abbreviation of display memory. Its main function is to temporarily store the data to be processed by the display chip and the processed data. The more powerful the graphics core, the more video memory it needs.
The previous video memory was mainly SDR, and the capacity was not large. In 2012, most of the graphics cards on the market used DDR3 video memory, and the latest graphics cards used GDDR5 video memory with better performance.
