Method for mounting fluid energy conversion experimental sleeve type tube ruler multi-reference pressure measuring device

Abstract

The invention relates to the technical field of mounting methods for fluid energy conversion experimental devices. The fluid energy conversion experimental sleeve type tube ruler multi-reference pressure measuring device comprises a frame, a pressure measuring device outer tube ruler, a pressure measuring device, dual slideways, a pressure measuring device inner tube ruler and a pressure-measuring pointer. The mounting method is characterized by comprising the following steps of: A. vertically welding a tubular central line of a dual slideway sleeve and the pressure measuring device inner tube ruler; B. sleeving the dual slideway sleeve on the dual slideways, wherein the pressure measuring device inner tube ruler is on the upper part, and the tube ruler has outward scales; C. horizontally mounting the dual slideways on two sides of the frame and pre-tightening the dual slideways; D. correcting the dual slideways to be horizontal by using a laser level gauge, and aligning the scale point 0 of the tube ruler with a low-level energy small-diameter tube and a central line of a level energy tube by using a vapor water level gauge, and fixing; E. sleeving the pressure measuring device outer tube ruler on the pressure measuring device inner tube ruler, wherein the window is outward; and F. sleeving the pressure-measuring pointer device on the scale area of a pressure-measuring device outer tube ruler of the pressure measuring device outer tube ruler.

Description

technical field [0001] The utility model relates to a multi-reference pressure measuring device of a casing type pipe ruler for a fluid energy conversion experiment, which relates to the technical field of installation methods of a fluid energy conversion experiment device. Background technique [0002] For incompressible fluids, when there is a steady flow in the pipeline, and the system exchanges reactive power with the environment, if the fluid per unit mass is used as the basis for calculation, due to the different flow velocities of the various cross-sectional areas of the pipeline, the horizontal benchmark of the pipeline The heights are different, and these differences make the corresponding static pressure heads different. The conversion relationship of fluid energy can be described by the energy constant calculation equation in the flow process, namely: [0003] z 1 + p 1 ...

AI Technical Summary

Problems solved by technology

None of the prior art fluid energy conversion experimental devices can accurately read the original data at one time, for example, use a box ruler to measure the height h of the piezometer liquid column from the upper end surface of the piezometer support 5 1 and the highest point of the low-level energy thin-diameter tube 6 to the upper end surface of the pressure measuring tube support 5 h 2 Height, and then measure the diameter of the low-energy thin-diameter tube 6 and divide it by 2 to calculate the sum of the three, that is, h 1 + h 2 +φ / 2 (see attached figure 1 And attached figure 2 ), the error of data accumulation is large, and the original data cannot be read directly. Once the accumulated data of mental calculation is wrong, the original record cannot be restored, which leads to the failure of the experiment
