Abstract
The utility model relates to a precision test-bed for testing the comprehensive performance of a blow head, which belongs to the technical field of the test of agricultural facilities or plant protection facilities. The utility model comprises a water conveying pipeline which is provided with a pressure regulating valve, and a fog collecting groove, and also comprises a door-shaped stand which is arranged above the fog collecting groove, wherein a cross beam of the stand is provided with the blow head which is to be tested; the water conveying pipeline is connected with the testing blow head which is to be tested through a flow sensor and a pressure sensor. When the utility model is used for testing, the signal output ends of the flow sensor and the pressure sensor are connected with the signal input end of a microcomputer, a water pump is started, a control valve is opened, and the conditions of parameters, such as the flow of the blow head, the angle of fog blowing, the distribution of fog quantity, etc., with the change of pressure. Therefore, the characteristic of the blow head can be known, fast and simple test conditions are provided to the research of a sprinkling irrigation facility, and the detection requirements of the blow head can be satisfied.
Description
Technical field
The utility model relates to a kind of test bed, and especially a kind of microtest platform that is used to test spray nozzle integrative performance belongs to agricultural or plant protection facility technical field of measurement and test.
Background technology
Shower nozzle is an agricultural irrigation and plant protection field facility commonly used, in other many fields application is arranged also, and it is of a great variety, and performance is different.In the past, adopt manual measurement such as the mensuration of sprinkler performance parameters such as flow, spreading of spray, the distribution of mist amount, precision can not guarantee, therefore can not satisfy agricultural, the research and development of plant protection science and technology and the series-produced detection demand of shower nozzle more.
Summary of the invention
The purpose of this utility model is: criticize the demand of production testing at agricultural, the scientific and technological research and development of plant protection and shower nozzle, proposes a kind of can the test simultaneously and comprise that flow, spreading of spray, mist amount are distributed in the spray nozzle integrative performance microtest platform of interior multinomial sprinkler performance parameter.
In order to reach above purpose, spray nozzle integrative performance microtest platform of the present utility model comprises hydraulic pipeline and the collection mist groove that pressure regulator valve is housed, also comprise the door shape stand that is installed in collection mist groove top, shower nozzle to be tested is installed on the crossbeam of described stand, and described hydraulic pipeline is surveyed shower nozzle by flow sensor, pressure transducer reception.
During test, the signal output part of flow, pressure transducer is connect the signal input part of microcomputer and so on test signal processes and displays device, start water pump, open by-pass valve control, can test the pressure-dependent situations of parameter such as capacity of sprinkler, spreading of spray, the distribution of mist amount simultaneously, thereby understand the shower nozzle characteristic,, and can satisfy the detection demand of shower nozzle for the research of equipment of sprinkler irrigation provides rapidly test condition easily.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
Embodiment one
Present embodiment is a micro-processor controlled spray nozzle integrative performance microtest platform, and major function is to finish the isoparametric test that distributes of total capacity of sprinkler, spreading of spray, mist amount, to detect the performance of shower nozzle.Its structure constitutes mainly due to hydraulic pipeline 1, door shape stand 2, collection mist groove 3 as shown in Figure 1.Door shape stand 2 is installed in collection mist groove 3 tops.In the hydraulic pipeline from the water pump end of driven by motor, tipping has pressure regulator valve 1-1, the first solenoid valve 1-2, buffer tank 1-3, filtrator 1-4, the second solenoid valve 1-5, flow sensor (model MUT500-MC308) 1-6, pressure transducer (model KYT1-10) 1-7, tensimeter 1-8 according to the order of sequence, finally is the shower nozzle to be tested 4 that is fixed on the stand crossbeam.In addition, also be furnished with LOAD CELLS 5, and design there is the turnover panel cut-off device.
The stand of this spray nozzle integrative performance microtest platform can three-dimensional regulation, and sampling, final proof can be controlled automatically.During test, test signals such as flow sensor, pressure transducer, LOAD CELLS are transferred in the microcomputer, by computer-automatic collection, processing in good time, directly show measured performance parameter values such as shower nozzle spreading of spray, liquid measure distribution, flow, and can finish characteristic curve protract,, finish simultaneously and comprise that pressure, flow, the isoparametric precision of spreading of spray measure synchronously the test report printout with diagrammatic form.The design of present embodiment spray nozzle integrative performance test board according to the ISO standard.Its performance parameter is as follows:
Total flow error at measurment≤± 1%
Shunt volume is measured :≤± 1%
Piezometry :≤± 1%
Spreading of spray is measured :≤± 5 °
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
