Description

[0002] As a core component of fluid transport systems, the pump body's sealing performance directly affects the equipment's efficiency and safety. In industrial production, pump bodies are widely used in water conservancy, chemical, and energy fields. Insufficient sealing can lead to minor issues like media leakage and energy waste, or even serious problems like equipment failure and safety accidents.

[0014] Preferably, a connecting plate is fixedly connected to the sealing cover, a plurality of studs are fixedly connected to the base plate, a plurality of fourth through holes are opened on the connecting plate, the studs are inserted into the fourth through holes, and nuts are threadedly connected to the studs.

In this case, the liquid inlet mechanism can be opened to allow liquid to enter the sealing cover until the liquid completely submerges the pump body. At this point, the location of the pump body leak can be observed. This utility model avoids the need to immerse every pump body in liquid during use. When a pump body leaks, only the leaking pump body needs to be immersed in liquid, thus improving the testing efficiency. Attached Figure Description

[0023] 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.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Referring to Figures 1-2, this utility model provides a pump body sealing performance testing device, comprising:

[0026] The tabletop 1 has a first through hole, a water tank 2 is installed in the first through hole, the water tank 2 is filled with a test liquid, the water tank 2 is made of transparent material, a number of first support legs 3 are fixedly connected to the bottom of the tabletop 1, an air supply mechanism is provided on the tabletop 1, the air supply mechanism is connected to a first rigid pipe 4, a valve 5 and a pressure gauge 6 are installed on the first rigid pipe 4, and a lifting mechanism is provided on the tabletop 1.

[0027] The testing mechanism includes a base plate 7, with several second legs 8 fixedly connected to the bottom surface of the base plate 7. A sealing cover 9 is detachably connected to the base plate 7. The sealing cover 9 is made of transparent material. A connecting nozzle 10 and a blocking block 11 are provided on the base plate 7. The connecting nozzle 10 is connected to the first rigid pipe 4 and is used to connect to the pump body 12. The blocking block 11 is used to seal the pump body 12. A first exhaust pipe 13 is connected to the sealing cover 9. A one-way valve 14 is installed on the first exhaust pipe 13. The outlet of the first exhaust pipe 13 faces downward. A liquid inlet mechanism is provided on the sealing cover 9. A lifting mechanism is connected to the base plate 7 through a transmission.

[0028] In this device, the water tank 2 is made of transparent material to facilitate observation of the inside of the water tank. The air supply mechanism is used to provide high-pressure gas. The pump body 12 is placed on the base plate 7. The connecting air nozzle 10 is used to connect to the pump body 12. The plug 11 is used to block other holes of the pump body 12. The first exhaust pipe 13 is used to discharge gas. When the pump body 12 leaks gas, the gas will be discharged from the first exhaust pipe 13. The one-way valve 14 can prevent liquid from entering the sealing cover 9. The lifting mechanism can move the base plate 7 up and down.

[0029] Before testing, the base plate 7 is raised using the lifting mechanism, and then the pump body 12 is placed on the base plate 7. The connecting air nozzle 10 is connected to the pump body 12, and the other openings are blocked using the plug 11. The sealing cover 9 is installed on the base plate 7, and the base plate 7 and the sealing cover 9 are fully immersed in the liquid using the lifting mechanism. Air is supplied to the pump body 12 through the air supply mechanism, and the pressure gauge 6 is observed. When the air pressure reaches the specified value, the valve 5 is closed to prevent gas backflow, and the pressure is maintained for a certain period of time. If there is a problem with the pump body 12, the air pressure inside the sealing cover 9 will increase, and the gas will be discharged through the first exhaust pipe 13. Since the outlet of the first exhaust pipe 13 faces downward, bubbles will only emerge from the first exhaust pipe 13 when the air pressure inside the sealing cover 9 increases, indicating a problem with the pump body 12. In this case, the liquid inlet mechanism can be opened to allow liquid to enter the sealing cover 9 until the liquid completely submerges the pump body 12. At this time, the location of the leak in the pump body 12 can be observed. This avoids the situation where each pump body 12 is immersed in liquid, improving the testing efficiency. When there is no air leakage in the pump body 12, no gas will be discharged from the first exhaust pipe 13.

[0030] In practical applications, if there are many orifices in the pump body 12, multiple plugs 11 can be used. The plugs 11 are tightly connected to the pump body 12 and can withstand high-pressure gas. In this embodiment, only one plug 11 is shown.

[0031] The scheme is further optimized. A first support plate 15 and a second support plate 16 are fixedly connected to the base plate 7. A first electric telescopic rod 17 is fixedly connected to the first support plate 15. A connecting air nozzle 10 is fixedly connected to the output end of the first electric telescopic rod 17. A block 11 is fixedly connected to the second support plate 16. A pad 18 is fixedly connected to the base plate 7. The pump body 12 is placed on the pad 18.

[0032] The first electric telescopic rod 17 drives the connecting nozzle 10 to move, which facilitates the installation of the connecting nozzle 10. The pad 18 is used to place the pump body 12 to prevent the pump body 12 from being damaged.

[0033] The solution is further optimized so that the liquid inlet mechanism includes a water inlet pipe 19 and a second exhaust pipe 20. The second exhaust pipe 20 is installed on the top wall of the sealing cover 9, the water inlet pipe 19 is installed on the side wall of the sealing cover 9, a first solenoid valve 21 is installed on the water inlet pipe 19, and a second solenoid valve 22 is installed on the second exhaust pipe 20.

[0034] When it is necessary to detect liquid entering the sealing cover 9, the first solenoid valve 21 and the second solenoid valve 22 are opened, and the second exhaust pipe 20 facilitates the rapid discharge of gas from the sealing cover 9. Liquid enters the sealing cover 9 through the first water inlet pipe 19.

[0035] The scheme is further optimized by connecting the air nozzle 10 with a first hose 23, and a second through hole is opened on the base plate 7. A connecting pipe 24 is fixedly connected in the second through hole. The first hose 23 is connected to the connecting pipe 24. The end of the connecting pipe 24 away from the first hose 23 is connected to a second hose 25. The second hose 25 is connected to the first rigid pipe 4.

[0036] The first hose 23 is completely inside the sealing cover 9, which facilitates the movement of the connecting nozzle 10. The connecting pipe 24 is used to connect the first hose 23 and the second hose 25. The second hose 25 facilitates the up and down movement of the base plate 7.

[0037] The scheme is further optimized. The lifting mechanism includes several second electric telescopic rods 26. Several first connecting rods 27 are fixedly connected to the platform 1. The top of the first connecting rods 27 is fixedly connected to the top plate 28. The second electric telescopic rods 26 are fixedly connected to the top surface of the top plate 28. The second electric telescopic rods 26 and the base plate 7 are connected by a connecting mechanism.

[0038] The top plate 28 is used to install the second electric telescopic rod 26, which drives the bottom plate 7 to rise or fall.

[0039] The scheme is further optimized. The connecting mechanism includes several second connecting rods 29 and a movable plate 30. The second connecting rods 29 are fixedly connected to the base plate 7, and the movable plate 30 is fixedly connected to the top of the first connecting rod 27. Several third through holes are opened on the top plate 28. The second connecting rods 29 pass through the third through holes and are movably arranged in the third through holes. The output end of the second electric telescopic rod 26 is fixedly connected to the movable plate 30.

[0040] The second link 29 is used to connect the movable plate 30 and the base plate 7. The second electric telescopic rod 26 drives the movable plate 30 to rise or fall, and the movable plate 30 drives the base plate 7 to rise or fall through the second link 29.

[0041] The scheme is further optimized. A connecting plate 31 is fixedly connected to the sealing cover 9, and several studs 32 are fixedly connected to the base plate 7. Several fourth through holes are opened on the connecting plate 31, and the studs 32 are inserted into the fourth through holes. Nuts 36 are threadedly connected to the studs 32.

[0042] When installing the sealing cover 9, align the fourth through hole with the stud 32, and then tighten it with the nut 36. The cooperation between the nut 36 and the stud 32 makes the installation and removal of the sealing cover 9 very convenient.

[0043] The scheme is further optimized. The gas supply mechanism includes an air pump 33 and a high-pressure tank 34. Both the air pump 33 and the high-pressure tank 34 are fixedly connected to the platform 1. The air pump 33 and the high-pressure tank 34 are connected through a second rigid pipe 35, and the high-pressure tank is connected to a first rigid pipe 4.

[0044] The air pump 33 is used to supply gas, and the high-pressure tank 34 is used to store high-pressure gas.

[0045] Before testing, the device is used to raise the base plate 7 using the second electric telescopic rod 26, completely removing it from the liquid in the water tank 2. Then, the pump body 12 is placed on the base plate 7, and the connecting air nozzle 10 is connected to the pump body 12. The other openings are then blocked using the plug 11. The sealing cover 9 is installed on the base plate 7 and connected using nuts 36 and studs 32. The second electric telescopic rod 26 retracts, causing the moving plate 30 to descend. The moving plate 30, via the second connecting rod 29, causes the base plate 7 to descend until it and the sealing cover 9 are completely submerged in the liquid. The air pump 33 is then started, supplying air to the high-pressure tank 34. The air enters the pump body 12. The pressure gauge 6 is observed. When the pressure reaches the specified value, the valve 5 is closed to prevent backflow of gas, and the pressure is maintained for a certain period. If there is an air leak in pump body 12, the air pressure inside the sealing cover 9 will increase, and the gas will be discharged through the first exhaust pipe 13. Since the outlet of the first exhaust pipe 13 faces downward, bubbles will only emerge from the first exhaust pipe 13 when the air pressure inside the sealing cover 9 increases, indicating a problem with pump body 12. At this time, the first solenoid valve 21 and the second solenoid valve 22 can be opened, and the second exhaust pipe 20 can quickly discharge the gas inside the sealing cover 9. Liquid enters the sealing cover 9 through the first water inlet pipe 19 until the liquid completely submerges the pump body 12. At this time, the location of the air leak in pump body 12 can be observed. This avoids the situation where each pump body 12 is immersed in liquid, thus improving the detection efficiency.
