Description
Technical field
The utility model relates to a kind of multipurpose test system, particularly a kind of dust free room basic parameter multifunctional testing bar.
Background technology
At present, between test wind speed time probe and the filtrator apart from 15cm (ISO14644-B.4.2.1.1). measuring distance often is not easy to fix during test.In addition, when using the air-flow angle of deviation of spike line test layer flow structure dust free room, use two lines to measure, the fixing weight of going up in single line bottom makes line vertical with ceiling, and single line is unsettled; Need to measure the deflection distance of spike line, and the point of test deflection distance is apart from the height of ceiling, in order to calculate the air-flow angle of deviation; Generally use the line of electrostatic prevention material to measure in order to reduce static for the influence of two lines, but because wire rod matter is softer, two lines are easy to be intertwined, and cause operating difficulties.Have again, will keep the distance of 1cm when measuring filter leaks between (simple detection method) laser particle counter probe and the filtrator, need high-rise working or will pop one's head in fixing and be put into correct position mensuration with bar.
Therefore, provide a kind of simple to operate, obvious results dust free room basic parameter multifunctional testing bar, have very important significance, become one of these those skilled in the art problem anxious to be addressed simultaneously for actual production.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of simple, practical, effective dust free room basic parameter multifunctional testing bar is provided.
The technical scheme that the utility model adopted is for achieving the above object: a kind of dust free room basic parameter multifunctional testing bar; It is characterized in that this reference test bar comprises main body bar, elongated body bar, fixedly sliding sleeve, locating platform and hook; The segmentation of described main body bar is threaded, and its top connects the elongated body bar, and described elongated body masthead end is connected with locating platform perpendicular to elongated body club shaft one side, and locating platform is provided with bottom outside and is provided with hook; Described fixedly sliding sleeve is sheathed on the elongated body bar.
The beneficial effects of the utility model are: its result is simple, and is reasonable in design, multiple functional, use easy, the effect highly significant.When the test wind speed, probe is fixed on the slide bar of top main body bar, on the multi-functional bar distance scale is arranged, easily the distance between static probe and the filtrator.When the test airflow angle of deviation, directly the spike line is hung on the hook on the multi-functional bar locating platform, wrapping phenomena can not take place.On the theme bar scale is arranged, directly measure the deflection distance, can calculate the air-flow angle of deviation (can be according to the distance of air-flow angle of deviation standard and measuring point and ceiling, calculate standard deflection distance, actual deflection distance is partial to then conformance with standard of distance less than standard during test, otherwise then do not meet standard, method of testing is easier).And the main body bar is a metal material, does not produce static, adsorption phenomena can not take place, and convenient and swift during test, error is less.When testing filters leaks, will pop one's head in and fix with top main body bar, convenient and swift during test.Test operation and production cost can be reduced greatly, be more suitable for industrialized production.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1 main body bar, 2 elongated body bars, 3 fixing sliding sleeves, 4 locating platforms, 5 hooks.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment that foundation the utility model provides:
Referring to Fig. 1, a kind of dust free room basic parameter multifunctional testing bar comprises main body bar 1, elongated body bar 2, fixedly sliding sleeve 3, locating platform 4 and link up with 5; Described main body bar 1 segmentation is threaded, and its top connects elongated body bar 2, and described elongated body bar 2 tops are connected with locating platform 4 perpendicular to elongated body bar 2 bodies of rod one side, and locating platform 4 is provided with bottom outside and is provided with hook; Described fixedly sliding sleeve 3 is sheathed on the elongated body bar 2.Be used for fixing the probe of measuring anemoscope, for example unit type P9555-P; Also can not install and fix sliding sleeve 3, and fixing anemoscope otherwise, for example: sticking etc. with adhesive tape.
Multifunctional testing bar main body bar 1 can be applicable to the dust free room of differing heights by the length of the control main body bar 1 that is threaded.Multifunctional testing bar main body bar 1 and elongated body bar 2 are provided with scale, and elongated body bar 2 length can be established 1m, are beneficial to suitable distance and read; Main body bar 1 length can be established 0.5m.According to dust free room height difference, general elongated body bar 2 adopts 2～4 joints.
Described locating platform 4 makes multi-functional bar and ceiling contact area increase, and it is vertical with ceiling to be beneficial to the multifunctional testing bar.The hook 5 that is provided with above is 2cm or adjusts as required apart from elongated body bar 2 nearest lateral extents.Available being threaded between hook 5 and the locating platform 4 also can be waited the connection of other method with welding.
This multifunctional testing bar adopts material: aluminium alloy etc. do not produce static, do not send out the material of dirt.
Using method of the present utility model:
1,, selects main body bar quantity, and will couple together on main body bar and the elongated body bar by screw thread according to the dust free room height.
When 2, measuring wind speed, the anemoscope probe is fixed on fixedly on the sliding sleeve, and makes that lateral extent is 15cm on probe and the locating platform; Locating platform is fully contacted with ceiling,, read numerical value on the anemoscope so that the main body bar is vertical with ceiling.
When 3, measuring the air-flow angle of deviation, the spike line is hung on the hook; (1) desirable when going out the concrete numerical value of air-flow angle of deviation, measure lateral separation apart from ceiling fixed position spike line, calculate the air-flow angle of deviation according to trigonometric function; For example apart from ceiling 1m place record spike line lateral separation be 1m then the air-flow angle of deviation be 45 °.(2) desirablely go out the air-flow angle of deviation when whether qualified, calculate spike line lateral separation according to trigonometric function apart from ceiling fixed range position, lateral separation with the actual spike line of the bar of the lateral separation that equals to calculate, when actual spike line lateral separation is big, then the air-flow angle of deviation does not meet standard, on the contrary conformance with standard then; For example standard air-flow angle of deviation is 14 °.In distance ceiling 1m position, spike line lateral separation should be less than 0.24m.With the lateral separation of bar that equals 0.24m and actual spike line relatively, lateral separation is during greater than 0.24m, and then the air-flow angle of deviation does not meet standard greater than 14 °, on the contrary conformance with standard then.
When measuring filter leaks, the cleanliness factor probe of tester is fixed on the elongated body bar of top, measures.
Above-mentioned with reference to embodiment to the detailed description that this dust free room basic parameter multifunctional testing bar carries out, be illustrative rather than determinate; Therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection domain of the present utility model.
