Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in Figure 1, the present embodiment provides a kind of device for fast detecting of cylindrical empty air filter windage comprising one
Frequency conversion fan 1, a ventilation shaft 2, flow meters 3, a differential manometer 4, an air filter erection joint 5, one are for carrying simultaneously
Go up and down the hoistable platform 6, a controller and a display screen 8 of air filter 10 to be measured.
Wherein, which is three-stage, and preceding segment pipe 21, middle segment pipe 22 and rear segment pipe 23 are sequentially connected, should
Ventilation shaft 2 uses segmented fast interface connection type, and the leakproofness of adjacent segment pipe is also ensured while easy for installation.
The frequency conversion fan 1 may be alternatively mounted on the ground for not interfering operation, and it is raw which is placed in air filter
Produce on assembly line 9, the air inlet of the frequency conversion fan 1 is connected with the air outlet of the rear segment pipe 23, the preceding segment pipe 21 and this
One end of air filter erection joint 5 is connected, and the differential manometer 4 is provided on the preceding segment pipe 21, in this on segment pipe 22
It is provided with the flowmeter 3, the flowmeter 3, the differential manometer 4 and the display screen 8 are electrically connected with the controller.
The diameter for the end that segment pipe 22 and the preceding segment pipe 21 connect in this is identical as the diameter of the preceding segment pipe 21, should
The diameter for the end that middle segment pipe 22 and the rear segment pipe 23 connect is identical as the diameter of the rear segment pipe 23, segment pipe 22 in this
Diameter in addition to both ends is less than the diameter at the both ends of segment pipe 22 in this, and segment pipe 22 is using variable diameter connection type point in this
It is not connect with the preceding segment pipe 21 and the rear segment pipe 23.
The other end of the air filter erection joint 5 is used to install the air filter to be measured 10 risen, specifically, should
The diameter of the mounting surface of the other end of air filter erection joint 5 is identical as the diameter of air filter 10 to be measured, the air
The mounting surface of filter erection joint is contacted with the air filter to be measured 10 of rise.
The range of the flowmeter 3 can be selected according to the specification of air filter to be measured, and different flow meter specification is corresponding
Suitable ventilation shaft diameter may be selected in different installation apertures, flowmeter specification after deciding.
The operating process of the device for fast detecting is detailed below:
1, according to the size of air filter to be measured, suitable air filter erection joint 5, and the sky that will be selected are selected
Before air filter erection joint 5 is mounted on segment pipe 21；
2, frequency conversion fan 1, flowmeter 3, differential manometer 4 are opened, and sets the required windage value of test, such as 500m3/h；
3, when the stream in production line of air filter 10 to be measured is gone on hoistable platform 6, hoistable platform 6 is raised up to
Test starts when the top of air filter 10 to be measured and the installation face contact of air filter erection joint 5；
4, flowmeter 3 detects the vent flow in ventilation shaft 2 and vent flow is transmitted to controller, and differential manometer 4 is examined
It surveys the windage value of air filter 10 to be measured and windage value is transmitted to controller；
5, vent flow and windage value are transmitted to display screen by controller, and test data can be read from display screen 8, are surveyed
Try hoistable platform 6 after stablizing about 8s to decline, be compared according to setting value and test value, can interpretation this air filter 10 to be measured it is qualified
Whether, it circulates and arrives next procedure (such as qualified air filter 11) if qualified, it is unqualified to be chosen, it circuits sequentially
Test next air filter.
Air inlet mode needed for test is induced draft, and frequency conversion fan 1 is mounted on device end, can continuously operate without stopping,
Windage value is also real-time display, so windage value will be shown after air filter to be measured installs, about waiting 10s is readable
Stability number out；Ventilation shaft diameter is small, and length is short, light-weight, can be suspended on above workshop, ground only needs a test position
Set the position placed with frequency conversion fan；The air inlet mode of detection device is negative pressure exhausting, and uses the air of the overwhelming majority now
The air inlet mode of clarifier and fresh air system is the same, and the mounting means of air filter to be measured is that plane compression sealing is installed, and four
360 degree of week, also as the filtering mounting means of air purifier and fresh air system now, which was surveyed around air inlet
Situation is tried closer to actual use situation, so test data can be more acurrate.
In addition to requisite instrumentations such as blower, flowmeter, differential manometers, the consumptive material of pipeline and spare part is less, low cost, each component it
Between connection be installed as rapid structural installation, structure is simpler.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that these
It is merely illustrative of, protection scope of the present invention is defined by the appended claims.Those skilled in the art is not carrying on the back
Under the premise of from the principle and substance of the present invention, many changes and modifications may be made, but these are changed
Protection scope of the present invention is each fallen with modification.
