The wall of the honeycomb duct is provided with multiple pressure holes, and each of pressure holes is connected with a corresponding pressure measuring glass tube via a silicone tube. Because the hydrostatics experimental apparatus is provided with multiple pressure measuring points and multiple differential pressure gauges, the working principles of the U shaped differential pressure gauge, the single tube pressure gauge, the liquidometer, the micro differential pressure gauge, the water seal and a communicating vessel can be demonstrated, positive pressure and negative pressure operations can be carried out, and the density of a certain liquid can be measured.
Description
Affiliated field
The utility model belongs to integrated form Experiment of Principles of Chemical Engineering device technique field, and what relate generally to is a kind of hydrostatics experimental provision.
Background technology
At present; In multiple fluid statics experimental provision; Generally can only demonstrate the principle of work of common differential manometer, linker, fluid-tight, but for being implemented in the elementary errors meter that carries out work under the principle of uniformity, liquid level gauge, positive negative-pressure operation and also not being seen in report through the statics experimental provision that Principles of Statics is measured some fluid density.
Summary of the invention
The purpose of the utility model provides a kind of statics experimental provision, and this device can be demonstrated the principle of work of U-shaped pipe differential manometer, single column manometer, liquid level gauge, elementary errors meter, fluid-tight, linker, can carry out positive negative-pressure operation, and can measure some density of liquid.
To achieve these goals; The utility model solves the technical scheme that its technical matters adopted: a kind of hydrostatics experimental provision; Comprise and increase and decrease circulating water chennel, the ebullator of pressing tube body and being arranged on its underpart; The mozzle on the cushion seal jar of right-hand member, liquid level gauge, water-air U-shaped differential manometer, kerosene-air U-shaped differential manometer, mercury-air U-shaped differential manometer, water-mercury dual liquid columns differential manometer, water-phenmethylol elementary errors meter, water-air single column manometer, water seal and top; On the tube wall of mozzle main body, have 8 pressure taps, each pressure tap is connected with separately pressure measurement glass tube through silicone tube, it is characterized in that: described increase and decrease pressure tube body is body always; The vertical installation, its underpart is connected with ebullator with the cushion seal jar.
The utility model all links with the cushion seal jar owing to each pressure gauge; Therefore can the pressure in the surge tank be read through the different pressures meter; Thereby the transformational relation between the various pressure gauge principle of work that can sharpen understanding and various pressure gauge reading, and can calculate some density of liquid.
