A lifting structure is symmetrically arranged in the middle of the lower surface of the base plate. A pressure detection structure is fixedly connected to the middle of one side of the upper surface of the water tank. A lifting plate is arranged on the upper part of the base plate and fixedly connected to the upper surface of the lifting structure. The upper surface of the lifting plate is symmetrically and fixedly connected to a shock-absorbing structure. The upper surface of the shock-absorbing structure is fixedly connected to a mounting plate. The upper surface of the mounting plate is symmetrically and fixedly connected to a fixing structure.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: In actual use, the port positions of pump bodies are generally not fixed when facing different pump bodies. However, the aforementioned technologies connect the pump body ports through fixed-position connecting pipes, which makes the equipment only applicable to testing pump bodies of a single specification, resulting in poor applicability and difficulty in meeting usage requirements.

[0005] Therefore, we propose a testing device for acid-resistant stainless steel pumps. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides an acid-resistant stainless steel pump testing device, which solves the problem that the above-mentioned technologies use a fixed-position connecting pipe to connect the pump body port, making the device only applicable to the testing of a single specification of pump body, resulting in poor applicability and difficulty in meeting usage requirements.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: an acid-resistant stainless steel pump testing device, comprising a testing mechanism, a fixing mechanism, and a connecting component. The testing mechanism includes a water tank, with connecting pipes fixedly connected to both sides of the water tank. A flow meter is installed on one of the connecting pipes. The fixing mechanism is located at the top of the water tank, and the connecting component is located at the end of the connecting pipe.

[0010] The connecting assembly includes a connecting disc fixedly sleeved on the end of the connecting pipe.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a testing device for acid-resistant stainless steel pumps, which has the following beneficial effects:

[0020] 1. This utility model, by setting up a testing mechanism, a fixing mechanism, and a connecting component, allows the stainless steel pump to be placed on a water tank and fixed by the fixing mechanism when testing the pump. Then, the connecting pipe can be pulled to connect the connecting pipe to the pump port through the connecting component. Since the connecting pipe can be stretched freely, it is convenient to test pumps of different specifications, thus improving applicability.

[0021] 2. By setting up a connecting component, when connecting the pump body, simply align the connecting plate with the flange at the pump body port, then rotate multiple L-shaped plates in sequence until the L-shaped plates are rotated to the back of the flange, and then rotate the stud to make the stud drive the clamping plate to press against the back of the flange, thus tightening the flange and the connecting plate together. This allows for quick connection of the pump body without the need for additional bolts, making operation convenient. Attached Figure Description

[0030] This utility model provides a technical solution:

[0031] Please see Figures 1-3A testing device for acid-resistant stainless steel pumps includes a testing mechanism 1, a fixing mechanism 2, and a connecting assembly 3. The testing mechanism 1 includes a water tank 11, with connecting pipes 12 fixedly connected to both sides of the water tank 11. The connecting pipes 12 are corrugated telescopic hoses, and a flow meter 13 is installed on one of the connecting pipes 12. The fixing mechanism 2 is located on the top of the water tank 11, and the connecting assembly 3 is located at the end of the connecting pipe 12. By setting up the testing mechanism 1, the fixing mechanism 2, and the connecting assembly 3, when testing the stainless steel pump, the stainless steel pump can be placed on the water tank 11 and fixed by the fixing mechanism 2. Then, the connecting pipe 12 can be pulled to connect the connecting pipe 12 to the pump port through the connecting assembly 3. Since the connecting pipe 12 can be freely stretched, it is convenient to test pumps of different specifications, thus improving applicability.

[0032] The water tank 11 is provided with a liquid level window 14 on one side. By providing the liquid level window 14, it is easy to observe the liquid level in the water tank 11 and replenish water in time.

[0033] Specifically, the fixing mechanism 2 includes a fixing seat 21 fixedly connected to the top of the water tank 11. A bidirectional screw 22 is rotatably installed on one side inside the fixing seat 21. Two symmetrically distributed clamping blocks 23 are threaded onto the bidirectional screw 22. A knob 24 is fixedly connected to one end of the bidirectional screw 22. A guide rod 25 is fixedly installed on the other side inside the fixing seat 21. The other end of the clamping block 23 is slidably sleeved on the guide rod 25. By setting the fixing mechanism 2, when fixing the pump body, the knob 24 can be rotated to drive the bidirectional screw 22 to rotate, so that the bidirectional screw 22 drives the two clamping blocks 23 to slide relative to each other along the guide rod 25, so that the clamping blocks 23 clamp and fix the pump body.

[0034] Specifically, the connecting assembly 3 includes a connecting disc 31 fixedly sleeved at the end of the connecting pipe 12. Multiple L-shaped plates 32 are hinged at the edge of the connecting disc 31. One end of the L-shaped plate 32 is threaded with a stud 33, and the other end of the stud 33 is threaded with a clamping plate 34. By setting the connecting assembly 3, when connecting the pump body, it is only necessary to align the connecting disc 31 with the flange at the pump body port, then rotate the multiple L-shaped plates 32 in sequence to rotate the L-shaped plates 32 to the back of the flange, and then rotate the stud 33 to drive the clamping plate 34 to abut against the back of the flange, thus pressing the flange against the connecting disc 31. The pump body can be quickly connected without the need for additional bolts, which is convenient for operation.

[0035] A sealing ring 35 is fixedly connected to the surface of the connecting plate 31. By setting the sealing ring 35, the sealing performance between the connecting plate 31 and the pump body flange can be improved.

[0036] The surface of the clamping plate 34 is fixedly connected with an anti-slip pad 36. By setting the anti-slip pad 36, the anti-slip effect of the surface of the clamping plate 34 can be improved.

[0037] In practical use, the working principle of this utility model is as follows:

[0038] First, when testing the stainless steel pump, the stainless steel pump can be placed on the water tank 11. Then, the knob 24 can be turned so that the knob 24 drives the bidirectional screw 22 to rotate, so that the bidirectional screw 22 drives the two clamping blocks 23 to slide relative to each other along the guide rod 25, so that the clamping blocks 23 clamp and fix the pump body.

[0039] Then, pull the connecting pipe 12 to align the connecting plate 31 with the flange at the pump body port. Then, rotate multiple L-shaped plates 32 in sequence to rotate the L-shaped plates 32 to the back of the flange. Then, rotate the stud 33 to drive the clamping plate 34 to press against the back of the flange, thus tightening the flange and the connecting plate 31. This allows for quick connection of the pump body. Then, the pump body can be started to allow the water in the water tank 11 to circulate through the two connecting pipes 12. The pump body can be tested by observing the flow meter 13.

[0040] In summary, this acid-resistant stainless steel pump testing device, by setting up a testing mechanism 1, a fixing mechanism 2, and a connecting component 3, allows for testing of pumps of different specifications by enabling the connecting pipe 12 to be freely stretched during the testing of stainless steel pumps, thereby improving its applicability.

[0041] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
