Abstract
A self-circulating small-sized water tunnel, which relates to a water tunnel used for carrying out research and test on different device or parts moved in fluid. It comprises of a column pipe with the section of square shape, and said column pipe is horizontal arranged, flow straightener are arranged on both ends of said column pipe respectively. Between two flow straighteners are arranged a test section, in which there placed a detachable upper cap that is connected with pressure sensing signal collector via circuitry. Reducing pipe, pump,flowmeter and flow control valve are connected with outer ends of two flow straighteners in the form of annular ring. It makes current state meet with test requirement through flow straighteners in shorter distance, test section arranges a detachable upper cap ,through which, automatic pressure distribution collection systems can be installed based on different test specimen. Test pressure can be transmitted to analysis equipment in time via pressure signal gatherer so as to determine and control the rate, velocity and pressure of current flow in water tunnel. Column pipe with section of square makes testpieces installation more convenient.
Description
Technical field
The utility model relates to a kind of water hole that the different device that moves or parts are studied test in fluid.
Background technology
In order to measure and control flow, flow velocity and the pressure that passes through in the water hole, different device or parts are tested, flowmeter and flowrate control valve are installed on circulation line, are provided with detachable loam cake at the middle part of cylindricality square tube, on cover and pressure transducer has been installed is carried out pressure test.Had only large-scale water hole in the past at the utility model, not resembling the utility model can move so at any time, the installation test specimen is flexible, and exact instrument such as available PIV, LDV have the small-scale structure water hole of pressing kinetic characteristic to carry out DCO research to different device or the parts that move in fluid.
The utility model content
But the utility model purpose is to design a kind of convenient test, test specimen is had the small-sized water hole of small and exquisite self-loopa of pressing the kinetic characteristic micrometric measurement.
The utility model comprises that one section section is foursquare column tube, described column tube level is to layout, the two ends of described column tube are provided with current regulator respectively, column tube middle part between two current regulators is provided with test section, detachable loam cake is set on test section, cover on detachable by circuit connection pressure sensor signal collector, connect reducer pipe, water pump, flowmeter and flowrate control valves two current regulator outer end ring-types.
The utility model adopts special-purpose current regulator to make flow-shape Pass Test requirement in short distance, and at test section proprietary test specimen loam cakes conveniently replaced, loading and unloading is housed, and can automatic pressure distribution collection system be installed according to different test specimens.Adopt the circulation system of water pump, flowmeter, flowrate control valve, test square tube section and constant-current stabilizer, because described column tube seals, wherein the pressure of Yun Dong fluid is variable, so can test pressure in time be sent to analytical equipment by the pressure signal collector, flow that passes through in mensuration and the control water hole and flow velocity, pressure, square experimental section make the testpieces installation measure more convenient.
Because common water pipe, particularly the connector of water pump, flowmeter, flowrate control valve is circular, and, realize intact connection between the two in order to form the square section stream section of convenient experiment, the two ends of the utility model cylindricality square tube connect circle side's transition conduit respectively.
Above-mentioned pressure sensor signal collector can be pressure transducer, also can be common measuring cell.
