Description

Technical Field

[0001] This utility model belongs to the field of sealing performance testing technology, specifically an oil pump sealing performance testing device. Background Technology

[0002] An oil pump is a mechanical device used to transport liquid oil, widely used in automobiles, machinery, and industrial production. Its main function is to draw oil from a storage container and deliver it to the required parts to provide lubrication, cooling, or power support. It plays a vital role in engines and mechanical systems, ensuring normal equipment operation and extending service life. The sealing performance of an oil pump is crucial in its operation. Good sealing performance can prevent oil leakage, reduce oil waste and the risk of contamination, and directly affect the pressure stability of the system, ensuring efficient operation of the oil pump. Therefore, sealing performance testing is required during the oil pump manufacturing process.

[0003] Traditional oil pump sealing tests involve filling the oil chamber with water through the inlet, then pressurizing it to force the water out of the outlet. The water volume is then measured using a measuring cup to determine if the pump is leaking. This method requires filling the pump with water, which must be drained after testing, and the pump's interior must be dried before further processing. Therefore, improvements are needed to address these issues. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figures 1 to 5 The present invention includes a device base 1, with a water tank 2 on the top of the device base 1. Water for detecting leaks is added to the inside of the water tank 2. A fixing plate 3 is fixedly installed on the top of the device base 1. An electric telescopic rod 4 is installed in the middle of the fixing plate 3. Two sliding rods 5 are symmetrically fixedly installed on one side of the fixing plate 3. A reinforcing diagonal rod 6 is fixedly connected between one end of the two sliding rods 5 and one side of the fixing plate 3. Movable sleeves 7 are movably fitted onto the surfaces of both sliding rods 5. A horizontal moving plate 8 is fixedly installed between the opposite ends of the two movable sleeves 7. The telescopic end of the electric telescopic rod 4 is connected to... A horizontally movable plate 8 is fixedly connected to the middle of one side, and an oil pump carrier plate 9 that can be moved horizontally and adjusted vertically is installed at the bottom of the horizontally movable plate 8; an air pump is installed on the top of the fixed plate 3, and a pipe is installed at the air outlet of the air pump. One end of the pipe is installed with a threaded connecting pipe for connecting to the oil pump inlet or outlet, and a pressure gauge and an exhaust valve are installed in the middle of the hose. The air pump, pipe, threaded connecting pipe, pressure gauge and exhaust valve are not shown in the attached drawings, and the air pump, hose, threaded connecting pipe, pressure gauge and exhaust valve are all existing technologies, thus enabling effective sealing tests.

[0020] Specifically, the oil pump inlet is connected to a threaded connecting pipe, and the outlet is sealed. The oil pump is then submerged in the water inside the water tank 2. The air pump is then started, allowing gas to be delivered to the oil pump through the pipe. At the same time, the internal air pressure of the oil pump is observed using a pressure gauge, and the presence of air bubbles in the water inside the water tank 2 is checked. This process is used to assess the sealing performance of the oil pump. After the test is completed, the oil pump is removed from the water by moving the oil pump towing plate 9 upwards. The test is then completed by releasing air through the vent valve and disassembling the threaded connecting pipe.

[0021] A long platform 10 is fixedly installed on one side of the device base 1. Support rollers 11 are installed at equal intervals on the top of the long platform 10. Through grooves 12 matching the support rollers 11 are installed at equal intervals in the middle of the oil pump carrying plate 9. The support rollers 11 are movably inserted into the inside of the through grooves 12. The length of the long platform 10 is greater than the length of the oil pump carrying plate 9, so that the oil pump can be effectively moved and loaded.

[0022] Specifically, the oil pump carrier plate 9 is moved to the top of the long platform 10 through the through groove 12, while the support roller 11 is located inside the through groove 12, and the top of the surface of the support roller 11 is higher than the top of the oil pump carrier plate 9. Then, the oil pump is moved by the rolling of the support roller 11, thereby moving the oil pump to the top of the oil pump carrier plate 9. Then, the oil pump is lifted and moved upward by the upward movement of the oil pump carrier plate 9.

[0023] The top of the oil pump towing plate 9 is fixedly connected to both ends of a first vertical rod 13 and a second vertical rod 14. The first vertical rod 13 and the second vertical rod 14 are staggered front to back and left to right. At the same time, the two second vertical rods 14 are located between the two first vertical rods 13. Rollers 15 are installed on the top of the two first vertical rods 13 and the two second vertical rods 14. A fixing block 16 is fixedly installed on the upper part of one side of the fixing plate 3. Two vertical through slots 17 are opened at both ends of the bottom of the fixing block 16. The two vertical through slots 17 at any end of the bottom of the fixing block 16 are staggered front to back and left to right. One end of the four vertical through slots 17 is aligned with the two first vertical rods 13 and the two second vertical rods 14 respectively. The top of the four vertical through slots 17 is provided with a curved wheel slot 18. The four rollers 15 are installed inside the four curved wheel slots 18 respectively. The four curved wheel slots 18 are composed of a short inclined slot, a horizontal slot and a long inclined slot, so as to effectively adjust the oil pump towing plate 9 for lifting and horizontal adjustment.

[0024] Specifically, the retraction of the electric telescopic rod 4 drives the horizontal moving plate 8 and the two moving sleeves 7 to move, so that the two moving sleeves 7 drive the horizontal moving plate 8 to move horizontally in a stable manner on the surface of the two sliding rods 5. The horizontal movement of the horizontal moving plate 8 is driven by the two first vertical rods 13 and the two second vertical rods 14 to move four rollers 15, so that the rollers 15 move upward at an angle within the short inclined groove inside the curved wheel groove 18 to the inside of the horizontal groove, then move horizontally inside the horizontal groove, and then move downward at an angle from the inside of the horizontal groove to the inside of the long inclined groove.

[0025] The upward, horizontal, and downward tilting movements of the four rollers 15 will cause the two first vertical rods 13 and the two second vertical rods 14 to move synchronously. This will cause the two first vertical rods 13 and the two second vertical rods 14 to move the oil pump carrier plate 9 and the oil pump on it, thereby moving the oil pump from the top of the oil pump carrier plate 9 to the water inside the water tank 2 for immersion.

[0026] This oil pump sealing performance testing device effectively tests sealing performance through a combination of a submersible structure and an airtight design. This combination avoids the need to fill the oil pump with water during testing and eliminates the need for subsequent drying of the pump's interior. This significantly improves the efficiency and quality of oil pump sealing performance testing. Furthermore, this device features a simple design, is easy to use and operate, and provides stable and reliable testing. Its performance meets the requirements for sealing performance testing.
