Abstract
The utility model relates to a flow force energy equation experimental device with an exhauster, which is characterized in that a vapor-barrier exhauster is arranged between a sewer pipe and an experimental pipe, and the interior of the vapor-barrier exhauster is divided by a vertical separation plate and an inclined blocking filter net into three spaces, i.e. a buffering exhaustion space, a collecting evacuating space and a rectifying press-out space; and a water inlet pipe on the vapor-barrier exhauster is communicated with the sewer pipe, a water outlet pipe on the vapor-barrier exhauster is communicated with the experimental pipe, a gradual-reduced exhaustion port on the vapor-barrier exhauster is communicated with an evacuating pipe, and the evacuating pipe is communicated with a drainage pipe. The flow force energy equation experimental device has good gas-liquid separation effect and eliminates the phenomenon that the gas enters the experimental pipe; and the experimental section is of a full single flow, so that the experimental measurement data which is obtained during the experimental process is correct.
Description
Technical field
The utility model relates to a kind of stream power energy equation experimental facilities, particularly a kind of stream power energy equation experimental facilities with air extractor.
Background technology
Stream power energy equation experimental facilities is effective experimental facilities of demonstrating, proving the basic physics theorem of fluid dynamics, basic physical concept.It can directly perceived, clear, effectively inquire into the main contents in the fluid dynamics basis, verifies basic law, fundamental equation in the fluid dynamics with experimental technique.In experimentation, need the spot speed that measures the fluid section, average velocity, the section static pressure of complete and accurate, the parameters such as dynamic pressure of section point, accurately obtaining these physical parameters is main tasks of stream power energy equation experimental facilities.
Existing stream power energy equation experimental facilities, in experimentation, be brought into the experiment pipeline section owing to exist a large amount of air in the fluid, make on the section of testing the air in the pipeline section and occupy 1/2～1/3 the flowing space, along with the space that flow velocity increase gas occupies is big more, pressure tester is in the gas even, has a strong impact on the accuracy of experimental data.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of stream power energy equation experimental facilities of novel band air extractor is provided.
The utility model is realized its purpose as follows: the stream power energy equation experimental facilities of described band air extractor is by water pump, elevated tank, downcomer, leak-off pipe, upper hose, experiment tube, low flush tank, the worm gear flowmeter, Flow Measurement Display Meter, support, return pipe constitutes, it is characterized in that being connected with between downcomer and the experiment tube trapping air extractor, trapping air extractor inside has been divided into three spaces by the vertical partition plate and the retaining air filter net that tilts: the buffering exhaust space, the gas collection space of bleeding, rectification extrudes the space, water inlet pipe on the trapping air extractor is communicated with downcomer, rising pipe on the trapping air extractor is connected with experiment tube, convergent exhausr port on the trapping air extractor is connected with exhaust tube, and exhaust tube is connected with leak-off pipe.The retaining air filter net that tilts is made up of the back up pad stainless steel filtering net.Experimental section uses transparent material, can observe the state of working fluid.
During the utility model work, connect pump power, experiment is delivered to elevated tank from low flush tank by water pump with liquid, elevated tank passes through spout hole to excess liquid, leak-off pipe returns low flush tank and forms the constant constant flow of liquid level homeostatic process pressure head, liquid in the elevated tank enters the trapping air extractor by downcomer, string has the liquid of gas at first to enter into the buffering exhaust space of trapping air extractor, it is moving that gas is gone up string along with liquid flows to, lighter gas enters into the gas collection space of bleeding, partly gas enters rectification with liquid and extrudes the space and kept off the air filter net and block and gather and float, make gas and fluid separation applications, isolated gas concentrates on the top of trapping air extractor, by the convergent exhausr port, exhaust tube links to each other with leak-off pipe, being in negative pressure state is extracted into isolated gas and part liquid in the leak-off pipe, thereby reach the purpose of gas-liquid separation and gas bleeding, flow into experiment tube through the rising pipe of the liquid after the gas-liquid separation through trapping air extractor bottom, the liquid of experiment tube of flowing through is the full packages flow state that a kind of no gas exists, the various Physical Experiment parameters that monitor in uniform full-section pipe-flow are accurate, can satisfy stream power dynamical foundation experimental requirements, the liquid that flows out from experiment tube flows back to low flush tank through return pipe, finishes the experiment circulation of liquid stream.
The utlity model has following advantage and good effect: simple in structure, easy to use, gas-liquid separation effect is good, has eliminated gas and has sealed in experiment tube section phenomenon, and experimental section is the individual event stream of full packages, and the measured data of experiment that is obtained in experimentation is accurate.
