Description
Technical field
The utility model relates to a kind of test system, particularly a kind of full-automatic draught fan performance test system.
Background technique
Blower fan is the custom abbreviation of China to gas compression and gas conveying machinery, and usually said blower fan comprises ventilator, blower.Blower fan carries out testing property at the Shi Douhui that dispatches from the factory, and guarantees that the performance of blower fan is qualified.Test according to GB/T1236-1985 " ventilator aerodynamic quality experimental technique " at China's fan performance.
In the testing property of present industrial fan, can be divided into the hand dipping analysis and based on two kinds of the test systems of DOS environment.When hand dipping is analyzed,, and, there is artificial error of calculations owing to need great amount of calculation because manual operation causes reading error easily.Drawing data needs the manual drawing plotted curve, very consuming time.And need the manual tune compressor flow to change, cause test process loaded down with trivial details.And there are problems such as operation interface is unfriendly based on the test system of DOS environment.
Summary of the invention
This novel disclosed a kind of full-automatic draught fan performance test system; Comprise blower fan 8, test runner 11, computer system 12; The air channel of blower fan 8 connects test runner 11; Torque sensor 5 is installed on the motor of blower fan 8 with speed probe 6, and torque sensor 5 is connected with computer system 12 respectively with speed probe 6.
Said test runner inboard 11 is equipped with pressure transducer 4, and the air channel installed inside of said blower fan 8 has pressure difference transmitter 7, and pressure transducer 4 is connected with computer system 12 respectively with pressure difference transmitter 7.
Said computer system 12 connects temperature transducer 1, humidity transducer 2 and barometric pressure sensor 3.
Said test runner 11 is provided with taper import 9, actuating motor band flow control valve 10.
Said computer system 12 is a single-chip microcomputer.Total head, static pressure, power of motor, the efficient of blower fan under different flow is calculated by the draught fan performance test system of the utility model through pressure reduction, pressure, motor speed and atmospheric environmental parameters in the draught fan performance test.Be converted into the data under the standard state again.Draw out characteristic curve of fan according to the standard state data at last.Standard state is meant rotating speed and the intake air density of blower fan when concrete working environment.
The fan performance characteristic curve is the plotted curve that is used for characterizing fan performance.In the use of blower fan, mainly be to be used for checking blower fan when some particular flow rate, whether its total head static pressure and power of motor can satisfy the demands.The fan performance characteristic curve by ventilator zero static pressure until zero import volume flow.Yet mostly just use a part, and the suggestion supplier should explain the import volume flow scope that blower fan adapts to.The ventilator characteristic of being drawn then can be restricted to this normal range of operation.Outside the normal range (NR) of import volume flow, the error of measured value has the trend of increase and possibly generate unsatisfied flow pattern at import or export.
Gather pressure, pressure reduction torque, rotary speed data respectively.By temperature transducer and pressure transducer measures ambient temperature and atmospheric pressure.Draw after the calculation of parameter of default value according to input, and on display device, show.After blower fan work, the internal resistance change in resistance of air channel pressure sensor converts pressure signal into through internal circuit, is undertaken obtaining measuring pressure after A/D conversion and the dimension conversion by single-chip microcomputer.Single-chip microcomputer calculates the data that record, and obtains current fans entrance flow.The inner pid control algorithm program of single-chip microcomputer is calculated controlled quentity controlled variable according to the drift indicator of setting value and present flow rate, after D/A conversion and voltage/current conversion, obtains the current signal of 4 ~ 20mA, and signal is transferred into actuating motor then.Actuating motor rotates the aperture of regulating flow control valve, thereby has realized the quantitative control to flow.
Testing procedure according to program setting is handled input value (air density of blower fan standard state, motor speed, blower fan small flow state volume flow Q min, blower fan rated condition volume flow Q e and testing time n); Initialization data, n point of the required measurement of setting test process.Utilize the flow setting type process of test system to test one by one again.All test is jumped out circulation after accomplishing, and test result is exported.Realized the automation of testing property process.
In process of the test, single-chip microcomputer is each to be measured all the data display of gathering on the single-chip microcomputer display device, realizes that test process is visual.The intermediate data storage that system acquisition is calculated is in the extraneous memory device of single-chip microcomputer.After experiment finishes, utilize supporting program (based on Matlab) that test result is analyzed, generate permanent speed curves figure of draught fan performance test and draught fan performance test form.Test result also will be stored in the extraneous memory device simultaneously, make things convenient for the tester to consult.
Adopt the full-automatic draught fan performance test system of the utility model, can realize the automatic collection and the processing of fan performance parameter, data processing accurately, reliable, can reduce labor intensity and avoid personal error effectively.In test process, show survey data in real time, make things convenient for tester's observation test process, judge working state of system.Whole test process only needs a tester to accomplish.System has realized the range performance of deciding of fan performance is tested, and only normal range of operation is tested, and has saved the test time, has given prominence to the emphasis of testing property.Multiple result treatment mode is convenient, flexible, can satisfy different demands.
