First: When purchasing a wireless electronic crane, we must first consider its function. With the rapid development of electronic technology and the rapid development of Internet technology, various weighing control devices have been born. To facilitate connection with instruments such as computers, reduce the attenuation of the output signal of the load cell. We have to choose a wireless electronic crane scale with an RS232 interface and a 20 mA current loop. This wireless electronic crane scale also has peeling clear, storage license plate number, print weighing information, automatic overload alarm, automatic password setting, Classifying and weighing other functions. So be careful when choosing.
Second: We must also consider its economic benefits when purchasing wireless electronic crane scales. We should not blindly choose expensive wireless electronic crane scales, and we should not blindly choose inexpensive electronic electronic cranes. Because both of these have drawbacks, the most appropriate choice is the king of cost, its cost is to use in the operation can reduce the link, can not save operating time, can not always stable weighing, can save space and so on.
PE is a kind of inert material. It can resist the corrosion of various chemical medium and microorganisms except for a few strong oxidants. Thr corrosion resistance of HDPE materials to common chemical medium under different temperature and medium concentration.
PE water supply pipe uses special polyethylene as raw material and is extruded once by plastic extruder. It is applicable for urban water supply network, irrigation and division project and agricultural sprinkler project, especially for acid and alkali resistant and corrosion resistance environment. Since the Pe Pipe adopts hot-fusion and electro-fusion connection, the integration of joints and pipe is realized. It can also resist circumferential stress generated by internal pressure and impact stress on axial direction. In addition, the PE pipe is free from stabilizing agent of heavy metallic salt and the material is non-toxic and free from scaling and bacteria breeding so as to aviod secondary pollution of drinking water.
