Embodiment 1

[0068] Example 1: The ground is horizontal, and the air outlet direction is vertically downward to send air

[0069] Such as Figure 9 As shown, the main body 11 stops directly below the air outlet to be measured, and the tester brakes the self-locking pedal on the wheel 12 to keep the main body 11 stationary. The tester unscrewed the GB834 stainless steel knurled thumb screw on the guide piece 13, and released the air volume cover 14 freely to the bottom. The tester stands in front of the handle 15, holds the left and right handles 15 with both hands and presses down hard, uses the first wire tube 16 and the second wire tube 17 to push the air volume cover upward along the guide 13, and waits for the air volume cover 14 to open. The flexible film pressure sensor 19 on the surface of the EPDM foamed sealing strip 18 on the top of the air volume cover frame 14a gives an alarm through the display device. The angle of the monitoring device 19a is retrieved through the terminal ...

Embodiment 2

[0070] Embodiment 2: The ground is horizontal, and the air outlet direction is vertically downward to supply air

[0071] Such as Figure 10 As shown, when the parking position in the tuyere area to be tested has a slope of no more than 30°, stop the body 21 directly below the tuyere to be tested, and the tester brakes the self-locking pedals on the wheels 22 to keep the body 21 stationary . The straightness of the main body 21 is ensured by inserting the connecting rod into different heights of the cross bar, and the frame and the base of the air volume cover are perpendicular to the air outlet direction of the air outlet.

[0072] The tester unscrews the GB834 stainless steel knurled thumb screw on the guide piece 23, and releases the air volume cover 24 to the bottom freely. The tester stands in front of the handle 25, holds the left and right handles 25 with both hands and presses down hard, uses the first wire tube 26 and the second wire tube 27 to push the air volume c...

Embodiment 3

[0073] Embodiment 3: Horizontal ground, side air supply at a certain angle of the tuyere

[0074] Such as Figure 11 As shown, there is a certain angle between the air outlet to be tested and the horizontal ground to supply air from the side. Stop the main body 31 directly below the air outlet to be tested, and the tester brakes the self-locking pedal on the wheel 32 to keep the main body 31 stationary. Adjust the first brake air strut 39c and the second brake air strut 39d on both sides of the body 31, so that the base 34b of the air volume cover 34 and the air volume cover frame 34a are turned sideways to ensure that the base 34b is perpendicular to the air outlet direction.

[0075] After ensuring that the overturning brake air strut is stable, the tester unscrews the GB834 stainless steel knurled thumb screw on the guide piece 33, and releases the air volume cover 34 to the bottom freely. The tester stands in front of the handle 35, holds the two left and right handles 35...

Abstract

The invention relates to an air volume cover testing device. The air volume cover testing device comprises a frame body, an air volume cover, a linkage structure, a sealing piece, a sensor and a control device, wherein the frame body comprises a body and wheels arranged on the body, the frame body can move freely so as to improve the testing efficiency, the air volume cover comprises a base and an air volume cover frame, the base is detachably connected with one end, away from the wheels, of the body, and the linkage structure is detachably connected with the air volume cover frame. According to the invention, the linkage structure drives the air volume cover to move up and down in the direction of the center line of the frame body, and the linkage structure is operated to drive the air volume cover to move up and down in the direction of the center line of the frame body, so that the air volume cover is attached to the air opening, the testing efficiency is improved, and theadaptability of the testing deviceis enhanced; and the sealing piece is arranged on the inner side of the air volume cover frame, the sensor is arranged on the sealing piece, the sensor sends collected information to the control device, and the attachment between the air volume cover frame and the air opening is improved through the effect of the sealing piece, so that the testing accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of electromechanical installation measurement, in particular to an air volume hood testing device. Background technique [0002] With the development of the national construction industry, buildings with different functions gradually enrich our lives, such as libraries, office buildings, office buildings, high-end hotel rooms and meeting rooms, etc. At the same time, people are putting forward higher and higher requirements for the comfortable environment of these buildings. Among them, the air volume of the air outlet is one of the important test indicators. design and specification requirements. According to GB50243-2016 "Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering" E.2, there are two test methods in the air volume measurement of the tuyere. The first method is to arrange the measuring points according to the requirements of the specification, use the anemom...
