Abstract
The invention relates to an air volume test system which comprises a gas collection port, an exhaust port and a fixing support, wherein the gas collection port is connected with an upstream sampling device by a fastener; the upstream sampling device is matched with a downstream sampling device to work; the downstream sampling device is connected with an air volume test bin; and an air outlet of the air volume test bin is equipped with the exhaust port. According to the air volume test system, with the adoption of the mode, the front of an airflow passes through to-be-tested equipment, and upstream and downstream gas flows of the to-be-tested equipment are detected and compared to judge the air volume of the to-be-tested equipment. The system has the advantages of high test efficiency, simple operating method, convenience in equipment maintenance and the like, and can improve economic benefits of an enterprise and enlarge enterprise production.
Description
Technical field
The present invention relates to the detection system field, particularly relate to a kind of wind quantity test system.
Background technology
The air measuring test unit is the air quantity test unit that is specifically designed to all kinds of smoke exhaust ventilators, vent fan etc.Its measuring principle is hamper formula flow measurement principle, uses standard major diameter slow speed jet as hamper, flows through the air mass flow of nozzle by the differential static pressure measurement of bioassay standard nozzle ends.The wind quantity test system can carry out the suction air volume test, also can carry out the exhaust air rate test, also can carry out deciding the air quantity test, can also carry out the constant static-pressure test.Wind quantity test of the prior art system, its practical performance is lower; And its work efficiency is low, can not effectively carry out the measurement of air quantity.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of wind quantity test system, and it is reasonable in design, and is simple in structure, can carry out the data designated test to measurand efficiently.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts provides a kind of wind quantity test system, and it is made up of a plurality of independently unit, comprising: gas is collected mouth, exhausr port and fixed support; Described gas is collected mouth and is connected the sampled upstream device by securing member; The work that cooperatively interacts of described sampled upstream device and sampled downstream device, the sampled downstream device connects the wind quantity test storehouse; The air outlet in described wind quantity test storehouse is equipped with described exhausr port.
Preferably, be provided with traversing carriage below the described sampled upstream device.
Preferably, be provided with the nozzle combination that is parallel to air flow in the described wind quantity test storehouse.
Preferably, the air inlet in described wind quantity test storehouse and air outlet are equipped with the homogenizing plate perpendicular to air flow.
The invention has the beneficial effects as follows: a kind of wind quantity test system is provided, makes air-flow positive by equipment under test, by detecting and the airshed of contrast equipment under test upstream and downstream is judged the air quantity of this equipment under test.The present invention its have the testing efficiency height, method of operating is simple, maintenance of equipment is convenient etc. manyly a bit can improve economic benefit of enterprises, enlarge enterprise and produce.
Description of drawings

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also accompanying drawing 1, the embodiment of the invention comprises:
A kind of wind quantity test system, it is made up of a plurality of independently unit, comprising: gas collects mouthful 1, exhausr port 2 and fixed support 3; Described gas is collected mouth 1 and is connected sampled upstream device 4 by securing member; Described sampled upstream device 4 belows are provided with traversing carriage 7.The work that cooperatively interacts of described sampled upstream device 4 and sampled downstream device 5, sampled downstream device 5 is provided with cylinder 10, is used for clamping tested filter 12; Described sampled downstream device 5 connects wind quantity test storehouse 6; The air outlet in described wind quantity test storehouse 6 is equipped with described exhausr port 2.Be provided with the nozzle combination 8 that is parallel to air flow in the described wind quantity test storehouse 6.The air inlet in described wind quantity test storehouse 6 and air outlet are equipped with the homogenizing plate 9 perpendicular to air flow.Described exhausr port 2 ends are connected with the exhaust fan 11 of auxiliary exhaust.
In use, as Fig. 1, tested filter 12 is clamped by cylinder 10, moving blower fan then blows, determine the test air quantity by nozzle combination 8, record the resistance of tested filter 12 by the static pressure ring, obtain the filtration efficiency of tested filter 12 by upstream and downstream samplings (atmosphere).
The invention provides a kind of wind quantity test system, make air-flow positive by equipment under test, by detecting and the airshed of contrast equipment under test upstream and downstream is judged the air quantity of this equipment under test.The present invention its have the testing efficiency height, method of operating is simple, maintenance of equipment is convenient etc. manyly a bit can improve economic benefit of enterprises, enlarge enterprise and produce.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
