Self-circulating electrical-testing total hydrostatic pressure tester

Abstract

The invention discloses a self-circulating electrical-testing total hydrostatic pressure tester which is provided with a lower water tank and a water pump arranged in the lower water tank, wherein thelower water tank and an upper water tank are connected by a water supply pipe, a water drain valve is arranged at the bottom of the upper water tank, a support seat is arranged at the upper part of the upper water tank, a lever and the support seat are connected to a fulcrum, a sector body is fixed at the lower end of one side of the lever and extends into the upper water tank, a lever adjustingscrew is arranged at the other side of the lever and connected with a ballasting body by a weight hanging rope, and the ballasting body is positioned on a force sensor; and an axial level bubble and astaff gauge are arranged on the sector body. The tester adopts an independent self-circulating constant-pressure water supply system, and is simple, convenient and intuitional in operation; the measurement of the total hydrostatic pressure by using the force sensor is creative initially and is accurate and intuitional; the lever fulcrum and the axial level bubble which are specially arranged eliminate dual influences from external force and force body deformation; the force arm length is accurate; and data is more accurate and reliable.

Description

technical field [0001] The invention relates to an experimental measuring instrument, in particular to a self-circulating electrical measuring hydrostatic total pressure experimental instrument. Background technique [0002] Hydraulic structures are often in direct contact with water bodies, so calculating the hydrostatic pressure on a pressure surface is a practical problem that is often encountered. Therefore, the hydrostatic total pressure experiment is an indispensable experimental item in the teaching experiment of hydraulics and fluid mechanics. [0003] At present, the method of measuring the total hydrostatic pressure of similar experimental instruments at home and abroad mostly adopts the method of manual force matching. However, this kind of traditional hydrostatic total pressure tester has certain disadvantages: first, the fan-shaped body lacks a horizontal alignment reference point, which makes it difficult to calibrate the vertical rectangular surface of the fa...

Problems solved by technology

However, this type of traditional hydrostatic total pressure tester has certain disadvantages: first, the fan-shaped body lacks a horizontal alignment reference point, which makes it difficult to calibrate the vertical rectangular surface of the fan-shaped body, resulting in cumbersome and time-consuming experimental operations; The experimental error caused by the displacement cannot be eliminated; thirdly, relying only on manual force matching, the subjective influence factor of the experimenter is relatively large, which affects the accuracy of the experiment
