In the field of modern security monitoring, wireless bridges are favored by various industries because of their convenient construction, easy expansion, low comprehensive cost and long transmission distance. So, what are the specific advantages of wireless bridges? The following Tengyuan Zhituo Xiaobian will explain in detail for you.
1. Compared with rural areas, which are sparsely populated and complex, wireless is easier to construct than wired, saving a lot of cumbersome cable wiring (some areas in rural areas cannot be constructed, wiring, etc.). In some places, only a pair of wireless bridges (one transmitter, one receiver) can be used for wireless transmission.
2, software and hardware maintenance is simple, safe and convenient.
3. The wireless networking is convenient for expansion and low maintenance cost. Compared with the wired network such as the twisted pair cable, the coverage area is wider and the mobile internet can be basically realized.
4. When the traditional wired network solves the problem of network connection between long distances, it is often necessary to lay a cable leased telecommunication line (need to pay an expensive telecommunication lease fee) or use a 3G network. The wireless network long-distance bridging solution can solve this problem by providing high-speed network transmission speed at a distance of 50 kilometers.
The above is a detailed introduction to the benefits of wireless bridges. More information can be focused on Tengyuan Zhituo, we will provide you with detailed answers.
Valves is one of the key components that affect engine reliability and safety. It's mainly used to start and shut down the intake and exhaust passages during engine operation, to control the intake of fuel mixture or air and the discharge of exhaust gases. . The working environment of the valve and Valve Seat is very harsh. In addition to the corrosion of high temperature gas, it also bears the impact of the burst pressure in the cylinder.
The material of the valve is usually divided into 40Cr, 4Cr9Si2, 4Cr10Si2Mo, 21-4N and 23-8N in China. 5Cr8Si2, 4Cr9Si3, 21-2N, 21-12N, 23-8N, XB, etc. have been used in large quantities on some imported models. High-temperature nickel-based alloys are also being used on high-load diesel exhaust valves.
