Embodiment
As shown in Figure 1, IVC cage box air-flow measurement module provided by the invention, comprising: cage box link, windage adjustment member and air flowmeter;
Cage box link one end connects tested IVC system cage box, and the other end connects windage adjustment member, and the windage adjustment member other end connects air flowmeter; Cage box link, windage adjustment member and air mass flow count formation one current path that is tightly connected; The windage sum that cage box link, windage adjustment member and air flowmeter produce equals the windage that tested IVC system cage box air filter produces, and windage adjustment member is circular pipe;
The windage that cage box link, air flowmeter and tested IVC system cage box air filter produce obtains by measuring, windage-cage box link windage-air flowmeter windage that the windage that such windage adjustment member produces=tested IVC system cage box air filter produces; Obtain the required windage that produces of windage adjustment member and calculated the length and internal diameter (different length coordinates different inner diameters, can produce identical windage) that can obtain windage adjustment member by Darcy formula.According to optimum embodiment, make the internal diameter equaling tested IVC system cage box air filter at the internal diameter of cage box link, windage adjustment member and air flowmeter.The windage that so only the length of windage adjustment member need be regulated can to regulate windage adjustment member to produce.The ventilation of cage box is gentle breeze environment, and therefore the present invention can ignore windage adjustment member material to the impact of windage, and the material of windage adjustment member is solid inflexibility material, can not be out of shape due to deadweight; Suggestion adopts ganoid material manufacture, can adopt metal material (such as aluminium alloy, stainless steel), Inorganic Non-metallic Materials (such as glass, pottery, PVC) etc.; The windage that the surperficial more lubricious material of windage adjustment member produces is less, and the simulation of IVC system cage box air-flow measurement module to IVC system cage box air filter windage is truer.
A manufacture method for IVC system cage box air-flow measurement module, comprising:
Manufacture and form with IVC system cage box air hole the cage box link be tightly connected, the cage box link other end connects windage adjustment member, and the windage adjustment member other end connects air flowmeter; Cage box link, windage adjustment member and air mass flow count formation one current path that is tightly connected; Windage adjustment member is circular pipe.
The windage sum that cage box link, windage adjustment member and air flowmeter produce equals the windage that tested IVC system cage box air filter produces.Windage adjustment member by change length and or internal diameter adjust its windage produced.
Preferably, the internal diameter of cage box link, windage adjustment member and air flowmeter equals the internal diameter of tested IVC system cage box air filter; In fixed inner diameter and when ignoring windage adjustment member material to windage effect, the length obtaining windage adjustment member can be calculated by Darcy formula.
A using method for IVC system cage box air-flow measurement module, by the air intake opening of IVC system cage box air-flow measurement module installation in two blow vents of IVC system cage box described in above-mentioned any one.
Wherein, described IVC system cage box air-flow measurement module installation is in two blow vents of IVC system cage box.
Below through the specific embodiment and the embodiment to invention has been detailed description, but these are not construed as limiting the invention.Without departing from the principles of the present invention, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection scope of the present invention.
