Abstract

The invention provides an impact type hydraulic turbine spray nozzle adjustable pad measuring device which comprises an adjustable pad, a runner and a spray nozzle. The adjustable pad is arranged between a spray nozzle flange and a water distribution pipe water outlet flange. One side of the water distribution pipe water outlet flange is tightly connected with one side of a middle flange. The other side of the middle flange is connected with a swing flange. An adjusting screw is installed between the middle flange and the swing flange. A centering swing device is arranged in the center betweenthe middle flange and the swing flange. The center of the other side of the swing flange is connected with the spray nozzle. A piano wire is arranged between the center of the spray nozzle and a section disc at the front end of the runner. A gasket, a centering disc and a spindle lower flange are arranged on the other side of the runner. One end of the gasket is connected with the centering disc.The other end of the gasket is opposite to the whole runner. The other end of the centering disc is connected with the spindle lower flange. According to the device, the impact type hydraulic turbinespray nozzle adjusting pad can be accurately measured, and the installation precision of the impact type hydraulic turbine spray nozzle is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fluid machinery, and in particular relates to a measuring device for an impact water turbine nozzle adjustment pad. Background technique [0002] The impact turbine is a kind of hydraulic prime mover that converts water energy into mechanical energy by means of a special water guiding mechanism to draw a free jet with kinetic energy, rushing to the water bucket of the runner, and making the runner rotate to do work, thereby completing the conversion of water energy into mechanical energy; in the impact turbine , according to the relative position of the working jet and the runner and the number of working times, it can be divided into cutting-type turbines, oblique-type turbines and double-click turbines. [0003] The nozzle is a key part of the impact turbine, and the installation accuracy of the nozzle directly affects the parameters of the impact turbine; among them, the adjustment pad is inseparable f...
