三、结构原理
1. 如下图所示:
同步电机
刻度圆盘
指针
游丝2. 同步电机以稳定的速度旋转，连接刻度圆盘，再通过游丝和转轴带动转子旋转。如果转子未受到液体的阻力，则游丝、指针与刻度圆盘同速旋转，指针
被测液体在刻度盘上指出的读数为“0”;反之，如果转子受到液体的粘滞阻力，则游丝产生扭矩，与粘滞阻力抗衡最后达到平衡，这时与游丝连接的指针在刻度盘上指示一转子comply with the corresponding requirements of materials and manufacturing standards. (4) all pipes, pipe fittings, valves, welding material must be carried out according to specifications, such as Visual inspection, after passing the qualifying marks; required strength and tightness of valves, seals after qualifying, required testing and adjusting the opening pressure of the relief valve, when they debug, seals; records and safety valve fill valve test debug logging. Stainless steel pipe and components shall not be in contact with carbon steel during storage. (5) building materials, such as sand, stones and other submission submitted in a timely manner, and keep the test report. (6) all materials are neatly stacked, by category, and clearly identified. high pressure pipeline construction prefabricated pipe (1) high pressure high pressure pipes should be tested before the pipe prefabrication, magnetic study after passing inspection, after passing the magnetic exploration, precast. (2) high-pressure pipeline isometric, factory prefabricated, and leaving the closed mouth, spot welding. (3) after the high pressure piping prefabrication, require heat treatment heat treatment should be carried out promptly. (4) after the high pressure piping prefabrication should be in time for the piping piping on number and order number on the same line marking. (5) the completion of prefabricated sections, inside should be cleaned and should be promptly closed nozzle. construction before the conditions of (1)
