Description
Technical field
The present invention relates to a kind of for paper permeability detector leakage tester and method of testing thereof.
Background technology
Paper permeability detector is a kind of specialized equipment for measuring paper permeability, and the permeability being mainly used in the Cigarette papers such as the cigarette paper in production of cigarettes, tipping paper, forming paper is measured.
Because the air permeability of paper has considerable influence for cigarette tar content, so paper permeability detector is the important instrument equipment that tobacco business uses.The leakage of instrument can directly affect Cigarette paper air permeability measurement result, and finally affects cigarette quality.
According to the requirement of standard GB/T/T23227-2008 " cigarette paper, forming paper, tipping paper and there is the mensuration of material gas permeable degree of directed air permeable belt ", under the condition on sealing gauge head assembly composition surface, should guarantee that the result of flow measurement is not more than 2cm
3/ min.
The main model of air permeability detector of domestic current use has A20, TQY-III, TQY500, D23 etc., structure and the principle of these air permeability detectors are incomplete same, but substantially all comprise source of the gas, pressure governor, measuring unit, the several part of gauge head assembly in its structure.Part instrument wherein self is with leakage detection function, but this leakage detection function realizes mainly based on the sensor of instrument internal, and this function has certain limitation, cannot measure when leakage rate is less time.At present, the universal external detection method for paper permeability detector Leak Detection has no relevant research report.
Summary of the invention
The one that object of the present invention proposes for above-mentioned prior art situation is just for paper permeability detector leakage tester and method of testing thereof, utilize pick-up unit of the present invention can detect the leakage situation of the paper permeability detector of each manufacturer, effectively solve the Leak Detection problem of various paper permeability detector.
The object of the invention is to be realized by following end scheme:
A kind of for paper permeability detector leakage tester, comprise by soap liquid box, the soap film flowmeter that is arranged on the rubber ball on soap liquid box and forms with the glass tube of scale mark, draft tube is connected with in glass tube bottom, wherein: set up one on the top of glass tube and to exert pressure arm, the other end of arm of exerting pressure is connected with an air punch cylinder.
The concrete grammar step utilizing aforementioned proving installation to carry out leak-testing to paper permeability detector is as follows:
(1) gas circuit between the pressure governor of air permeability detector and measuring unit is disconnected, pressure governor is connected with the inlet end of soap film flowmeter by use silicone tube respectively, measuring unit is connected with the outlet side of soap film flowmeter;
(2) with BOPP film, the gauge head module testing mouth of air permeability detector is sealed, select the Leak Detection of air permeability detector or calibration function that test port is closed, the path of air-flow is completely enclosed;
(3) extrude rubber ball and produce soap bubble in glass tube, utilize syringe to regulate the position of soap bubble, the bubble face of soap bubble is overlapped with 0, glass tube high scale line;
(4) start stopwatch and start timing, observe the number of division of soap bubble movement in 1 minute, if soap bubble is moved beyond 2 milliliters, then can judge that detector does not meet standard-required, if the amount of soap bubble movement is less than 2 milliliters, then detector meets standard-required.
Invention mechanism of the present invention and process are: between the pressure governor first soap film flowmeter being connected in series to air permeability detector and measuring unit, and utilize BOPP diaphragm seal instrument test mouth, then whole current path is all closed.Then at generation soap bubble, syringe can be utilized can to regulate the position of soap bubble, the bubble face of soap bubble overlapped with scale mark, is convenient to reading by extruding rubber ball.When arrival is stablized, the soap bubble in soap film flowmeter should not produce movement.If soap bubble moves, illustrative system exists and leaks, and the time utilizing stopwatch to record soap bubble to move a certain distance, can calculate the leakage rate of instrument.
Compare other air-flow measurement equipment, the soap film flowmeter adopted in the present invention is with low cost, and accuracy of measurement is high.Method of the present invention is simple to operate, and testing result is intuitively accurate, and versatility is good, is applicable to the Leak Detection of the paper permeability detector of different manufacturers.
