Abstract
The invention relates to an air filter test board. The air filter test board is formed by a primary pipeline, and the primary pipeline is sequentially provided with an air supplying unit, a filter fixing unit and an exhaust fan; the pipeline at the tail end of the air supplying unit is provided with a gas flow meter; the pipeline between the gas flow meter and the filter fixing unit is provided with a dust generating device; and sampling and detecting devices are arranged at two ends of the filter fixing unit. The air filter test board having the above structure allows the practical performances of an air filter to be balanced through comparing the gas qualities at the inlet and outlet of the air filter. The air filter test board has the advantages of effective control of the test process, guarantee of the smooth implementation of tests, simplicity, easy operation, and great increase of the test efficiency.
Description
Technical field
The present invention relates to the detection system field, particularly relate to a kind of air filter test board.
Background technology
The examination criteria of filtrator and method be along with the progress of filtrator and other correlation detection technologies progressively development with develop.At present, domestic air strainer detection system is divided into high efficiency particulate air filter detection system and general the ventilation with air strainer detection system two classes.General ventilate with the detection of air strainer from count the weight method, colourimetry changes particle sizing and counting method into; The efficient of high efficiency filter detects also generally, and tendency adopts particle sizing and counting method.The content that detects mainly is resistance and the efficient of filtrator, by the data analysis of sample being judged the work efficiency of filtrator.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of air filter test board, and it is reasonable in design, can effectively measure air strainer work efficiency.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts provides a kind of air filter test board, is made of main line, is provided with successively on the described main line: the unit of supplying gas, filter fixed cell and exhaust blower; The pipeline of the described cell end of supplying gas is provided with gas meter; Pipeline between described gas meter and the filter fixed cell is provided with sends out the dirt device; The two ends of described filter fixed cell are provided with sample detecting equipment.
