Abstract
The utility model embodiment discloses a kind of air permeability detector, comprise protection filtrator, the below of protection filtrator is respectively arranged with the first differential pressure pickup and multiple test conversion head, multiple test conversion head is connected in parallel and is connected in series with the first differential pressure pickup, the other end of described multiple test conversion head protects the second differential pressure pickup of filter interior to be connected in series with being arranged at, this programme have employed cylinder and feeds and carry out filter material and be installed, then closedown filter material Dust guard cover is carried out, automatically test according to test request, scene bigger than normal or less than normal is there is if there is measuring head, instrument can change measuring head aperture automatically, then retest, until complete test, protective cover adopts the two-stage filter of safeguard measure to protect, effectively prevent the particle affecting filter material performance from entering filter material, testing efficiency can be improved while minimizing manual operation, and avoid the impact at test environment, also carried out the security implication of production environment noise simultaneously.
Description
Technical field
The utility model relates to detector field, particularly relates to a kind of air permeability detector.
Background technology
At present, known air permeability detector is tested sensing, temperature sensing and circuit control system and micro computer computing system, filter material by source of the gas (air pump), minute-pressure and is clamped system and form.When testing filter material air permeability; need manually be installed by filter core and put into jig, then artificial some features according to material carry out estimation air permeability, carry out matching corresponding test aperture gauge head; if this structure estimation is inaccurate; want repeated multiple times test to carry out replacing different pore size measuring head, and filter material is placed in jig, without any protection; most environmental requirement is stricter; particularly dust, in the test of long period, dust blocking filter material hole can have influence on test result; The larger noise of easy generation.
Utility model content
The utility model embodiment technical matters to be solved is, providing a kind of can improve testing efficiency while minimizing manual operation, and avoids the impact at test environment, has also carried out the air permeability detector of the security implication of production environment noise simultaneously.
Described air permeability detector; comprise protection filtrator; the below of described protection filtrator is respectively arranged with the first differential pressure pickup and multiple test conversion head; described multiple test conversion head is connected in parallel and is connected in series with described first differential pressure pickup, and the other end of described multiple test conversion head is connected in series with the second differential pressure pickup being arranged at described protection filter interior.
Described protection filtrator is outside equipped with protective cover.
Implement the utility model embodiment, there is following beneficial effect:
This programme have employed cylinder and feeds and carry out filter material and be installed; then closedown filter material Dust guard cover is carried out; automatically test according to test request; scene bigger than normal or less than normal is there is if there is measuring head; instrument can change measuring head aperture automatically, then retests, until complete test; protective cover adopts the two-stage filter of safeguard measure to protect, and effectively prevents the particle affecting filter material performance from entering filter material.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model embodiment air permeability detector, comprise protection filtrator 1, the below of protection filtrator 1 is respectively arranged with the first differential pressure pickup 2 and multiple test conversion 3, multiple test conversion 3 is connected in parallel and is connected in series with the first differential pressure pickup 2, the other end of multiple test conversion 3 protects the second differential pressure pickup 4 of filter interior to be connected in series with being arranged at, protection filtrator 1 is outside equipped with protective cover, multiple test conversion head can automatically switch to suitable number according to test result, to reach test purpose, the present embodiment adopts an automatic card-loading filtering material, according to the flow automatically changing opening size test head adjustment turnover gas, reach test result requirement, at the exterior filtration protective cover of filter material jig, avoid environmental factor to the tests affect of filtering material, noise is controlled, meet noise circumstance requirement, after test terminates, do not calculate, but prompting input want test result corresponding standard, then calculate.According to result of calculation, generate test report list, select different needing result and provide corresponding curve map as required.And then print.
This programme have employed cylinder and feeds and carry out filter material and be installed; then closedown filter material Dust guard cover is carried out; automatically test according to test request; scene bigger than normal or less than normal is there is if there is measuring head; instrument can change measuring head aperture automatically; then retest; until complete test; protective cover adopts the two-stage filter of safeguard measure to protect; effectively prevent the particle affecting filter material performance from entering filter material; testing efficiency can be improved while minimizing manual operation, and avoid the impact at test environment, also carry out the security implication of production environment noise simultaneously.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
