DTH (Down the Hole) drilling tool including dth hammer, dth bit, and dth drill pipe. DTH bit is mady by tungsten carbide buttons and steel, with special heat treatment to improve the drill bit hardness and drill bit surface is compressed to improve the drill bit wear-resistance. Combine the quality raw material and the mature produce experience makes our DTH drill bit have long service lifeand good performance in thehard formation and widely used for large scale mine (open and underground), open quarry, water-well drilling, tunnel, geothermal drilling, subway engineering drilling, roads, power stations, and other construction projects, we can supply DTH drilling tool with high air pressure, middle air pressure and low air pressure.

POE switch usage precautions?
POE switch usage precautions?
With regard to POE switches, we have more or less certain understanding. POE power supply switches use the network cable as the remote power receiving terminal to provide power for the network. It contains two major functions of the network switch and POE power supply. It is common in POE power supply systems. Power supply equipment. This approach eliminates the need for separate power cables for each AP, IP camera, and IP phone, which can significantly reduce deployment costs. Although we know that POE-powered switches can save us some of the cost of power supply, what should we pay attention to during the purchase and use?
1, the top line, this dried, used, and eaten losses know. The quality of the network cable is crucial to the success of POE power supply. Generally, five types of network cables, super five cable cables, and six network cables are generally recommended. The internal material of the cable is also very important. Do not use any aluminum wire, copper clad aluminum wire, copper clad wire, iron core wire, etc. Pure copper wire is the best choice.
2. Theoretically, the POE power supply distance is within 100 meters within a distance of 80 meters. However, in view of the quality of the market's internet cable and the influence of the environment, the actual power supply distance is maintained within 80 meters.
The POE switch Xiaobian reminds you that POE power supply is only one of the power supply methods for many engineering projects. There are many other ways that have their own applicability. It does not matter whether it is good or bad. Everyone can use it according to the project needs and construction difficulty.
About the classification and selection of POE switches , and the use of attention do you understand? I hope this knowledge will help you in the future.
