In the construction of hydropower stations in the past, the large-diameter water-conducting pressure steel pipe was artificially welded by four curved steel plates, which was time-consuming, labor-intensive, and difficult to control. The new large-diameter steel pipe rolling technology developed by the Hydraulic Machinery General Factory adopts a one-time overall roll forming scheme, a one-time fully automated integral roll-formed pressure steel pipe, which has passed the State Key Laboratory—Lanzhou University of Technology. All-round scientific testing, all data indicators meet or exceed the design requirements. On November 23, at the results appraisal meeting organized by Huanghe Company, this technical solution was reviewed by domestic experts as “domestic leadingâ€. This equipment has changed the traditional manufacturing process of pressure pipe manufacturing in the past, increasing the technological content, improving the mechanization level and labor efficiency.
Intelligent water meter is a new type of water meter that uses modern microelectronic technology, modern sensing technology and intelligent IC card technology to measure water consumption, transfer water consumption data and settle transactions. This kind of water meter has the following three advantages: first, without manual meter reading; Second, save labor cost; Third, improve the efficiency of meter reading.
Smart water meters adopt point-to-point remote transmission mode. If a water meter has a problem, it will only reflect the problem of the user's water pipe, and will not affect other users, which also brings great convenience to the maintenance of water meters and meter reading work in the later stage.
