[0002] The centrifugal industrial fan performance test bench is designed to eliminate interference factors in actual applications, ensuring accurate and systematic testing of various performance indicators of centrifugal industrial fans. This test bench comprehensively evaluates key parameters of industrial fans, such as efficiency, noise, and stability, by simulating actual operating conditions, such as different air volumes, air pressures, and rotational speeds.

[0003] During prolonged use, the centrifuge in the performance testing equipment of the industrial fan undergoes certain material deformation, especially in the contact area with the bottom pad. This deformation gradually leads to gaps between the centrifuge and the pad, resulting in a lack of stable bottom support structure during operation. Due to this lack of sufficient support, the centrifuge generates unnecessary vibrations during operation. These vibrations not only reduce the equipment's operating efficiency but may also damage the overall structure, thus affecting its performance. Therefore, improvements are needed to address these deficiencies. Utility Model Content

[0004] The purpose of this invention is to provide a performance testing device for industrial fans, aiming to solve the problem that during long-term use, the centrifuge in the industrial fan performance testing device undergoes certain material deformation, especially in the contact area with the bottom pad.

Due to the lack of sufficient support, the centrifuge generates unnecessary vibrations during operation. These vibrations not only reduce the operating efficiency of the equipment but may also damage the overall structure of the equipment, thereby affecting its performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a performance testing device for an industrial fan, including a fan frame, a control console mounted on the fan frame, one end of the fan on the fan frame connected to a centrifuge, the other side of the centrifuge connected to a motor, a vertical plate connected to the bottom of the motor, and an adjusting rod threaded through one end of the vertical plate near the bottom.

[0008] The surface of the ear is welded with an internally threaded post, and two symmetrical sliding grooves are provided on the bottom of the slide. An insertion port is provided on the surface of the slide on both sides of the notch.

[0009] To mitigate the impact of instantaneous pressure on the slide when the support moves downwards, as a performance testing device for industrial fans according to this utility model, preferably, the support has an arc-shaped opening on its surface, a rectangular block is bonded to the center of the bottom of the support, and a side block is welded to each side of the support.

The rectangular block is made of deformable hard rubber. Two pins are symmetrically installed at the bottom of the support, and each pin is matched with a socket.

[0010] In order to enable the slide table to move back and forth on the wind tunnel frame, as a performance testing device for industrial fans according to this utility model, preferably, the slide table slides and connects to the corresponding slide rails through two slide grooves at the bottom, and the slide table forms a sliding adjustment mechanism with the wind tunnel frame through the upright plate, adjusting rod and bearing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4. This utility model provides the following technical solution: a performance testing device for an industrial fan, including a fan frame 1, a control console 2 installed on the fan frame 1, one end of the fan on the fan frame 1 being connected to a centrifuge 3, the other side of the centrifuge 3 being connected to a motor 4, a vertical plate 5 being connected to the bottom of the motor 4, and an adjusting rod 6 threaded through one end of the vertical plate 5 near the bottom.

[0024] One end of the adjusting rod 6 is fixedly connected to the inner ring of the bearing 7. One side of the outer ring of the bearing 7 is fixedly connected to the outer wall of the slide table 8. The bottom of the slide table 8 is connected to the support platform 10. The bottom of the slide table 8 is movably mounted on the slide rail 9. The bottom of the slide rail 9 and the vertical plate 5 are both fixedly mounted on the air duct frame 1. The surface of the support platform 10 is movably connected to the bottom of the centrifuge 3.

[0025] After the centrifuge 3 is started by the motor 4, the force generated by the centrifuge 3 accelerates the airflow and changes its direction within the duct, thereby generating the required air pressure and volume. The control console 2 can capture and record these key data in real time, thus enabling comprehensive testing and evaluation of the industrial fan performance. The following are existing technologies; for details, please refer to: DYT012 Centrifugal Fan Performance Test Bench.

[0026] Preferably, a notch 81 is provided at the center end of the surface of the slide table 8, a side lug 82 is welded on each side of the slide table 8, an internally threaded post 83 is welded on the surface of the side lug 82, two slide grooves 84 are symmetrically provided at the bottom of the slide table 8, and an insertion port 85 is provided on the surface of the slide table 8 on both sides of the notch 81.

[0027] The surface of the slide table 8 does not make direct contact with the bottom of the support table 10. When in use, the rectangular block 102 at the bottom of the support table 10 is inserted into the notch 81 on the slide table 8. When the support table 10 exerts instantaneous downward pressure, the rectangular block 102 will be squeezed and deformed, thereby reducing the impact.

[0028] Preferably, the support platform 10 has an arc-shaped opening 101 on its surface, a rectangular block 102 is bonded to the center of the bottom of the support platform 10, and a side block 104 is welded to each side of the support platform 10. A screw 105 is threaded through the surface of the side block 104. The length and width of the rectangular block 102 are smaller than the size of the notch 81, and the height of the rectangular block 102 is greater than the internal depth of the notch 81. The rectangular block 102 is made of deformable hard rubber. Two inserts 103 are symmetrically installed at the bottom of the support platform 10, and each insert 103 is matched with a socket 85.

[0029] In practical use, when the support platform 10 moves upward, it will drive the insertion post 103 to move upward synchronously. When the insertion post 103 moves upward, it will gradually move upward from the corresponding insertion port 85. This can prevent misalignment between the support platform 10 and the slide table 8 when they are separated. Furthermore, the maximum separation distance between the support platform 10 and the slide table 8 is less than the vertical length of the insertion post 103.

[0030] Preferably, the slide table 8 is slidably connected to the corresponding slide rail 9 through two slide grooves 84 at the bottom, and the slide table 8 forms a sliding adjustment mechanism with the air duct frame 1 through the upright plate 5, the adjusting rod 6 and the bearing 7.

[0031] In practical use, the adjusting rod 6 drives the bearing 7 to move through the threaded structure between it and the vertical plate 5. When the bearing 7 moves, it drives the slide table 8 to move. When the slide table 8 moves, it drives the bottom slide groove 84 to slide on the slide rail 9. In this way, the slide table 8 can be adjusted back and forth through this structure.

[0032] Preferably, each side block 104 is opposite to a side lug 82, and the threaded through hole on the side block 104 is opposite to the opening on the internal threaded post 83. The screw 105 passes through the side block 104 and is threadedly connected to the internal threaded post 83.

[0033] In practical use, the thread structure adopted by the screw 105 and the side block 104 has a spiral direction that is opposite to that of the thread structure on the internal thread column 83.

[0034] When a gap forms between the bottom of centrifuge 3 and the support platform 10, if this gap is not addressed promptly, it will affect the stability and efficiency of centrifuge 3 during operation, and may even pose a potential threat to its service life. To ensure that the support platform 10 can effectively and tightly support the bottom of centrifuge 3 again and restore its original supporting function, the following adjustment steps can be taken:

[0035] First, using the adjusting rod 6, smoothly and accurately push the slide 8 to the bottom of the centrifuge 3. Once the slide 8 reaches the predetermined position, its upper support 10 will precisely align with the bottom of the centrifuge 3, preparing for the subsequent adjustments.

[0036] Next, the two screws 105 need to be rotated simultaneously and evenly. These two screws 105, through their precise threaded structure with the internal threaded post 83, generate a stable lifting force. As the screws 105 rotate, they will cause the support platform 10 to move slowly upwards until it is tightly fitted against the bottom of the centrifuge 3. During this process, close attention must be paid to the rising of the support platform 10 to ensure smooth and precise adjustment, preventing damage to the equipment due to over- or under-adjustment.

[0037] Ultimately, through this series of fine adjustments, the slide 8 and its upper support platform 10 will be firmly supported at the bottom of the centrifuge 3, forming a stable support structure. This adjustment not only effectively prevents excessive vibration at the bottom of the centrifuge 3 due to lack of support, but also ensures that the centrifuge 3 maintains high stability and accuracy during high-speed operation, thereby avoiding any adverse effects on the centrifuge 3's performance and guaranteeing its long-term, efficient, and stable operation.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
