Piezoelectric Control Switch And The Key Technology Research

The traditional water dispenser requires agencies repeatedly pulling underground operations, time-consuming, increasing costs, especially after the underground organization corrosion and scaling can not be normal tripping operation, not only greatly extended the construction period, but also by big construction difficult. The recent use of underground water distribution technology voltage-controlled switches, pressure sensors can be received through the water from the ground control information, which replaced the cable for the exchange of information between ground and underground methods. In the case of the fixed string, from the ground to achieve the deployment and the underground opening and closing the control wells, compared with the conventional process, reducing the workload of pulling water nozzle and the cost of debugging and improve sub-injection effect. Also a good solution to deploy in the face of conventional instruments, " Don't go and don't pick up" and so on. With easy operation, safe, reliable, low cost, short construction period features. Column can be used to complete a trip underground layer of water injection and opening and closing pressure measurement functions well, deployment of wide, free to frequent manipulation. Field of application shows that the voltage-controlled switches with water smart technology is a good complement to traditional techniques.
