Description

Technical Field

[0001] This utility model relates to the field of pump head testing technology, and in particular to a pump head testing device with a material sorting and screening function. Background Technology

[0002] The pump head testing equipment can test the pump head's sealing performance by simulating pressing operations to observe for leaks and ensure a good seal; assess flow accuracy by measuring the output flow rate with each press to determine if it meets design requirements and ensure accurate flow control; test pressing force to determine the minimum pressing force and force variation, ensuring easy and uniform use; and test durability by simulating frequent use through repeated pressing to assess whether it can withstand long-term testing, providing a basis for quality and lifespan.

[0003] When testing existing press pump heads, unstable clamping can lead to inaccurate test data. Due to pump head shaking or displacement, data such as flow rate and pressure have large errors, which cannot reflect performance and make it difficult to assess durability. Uneven force can cause excessive wear in some parts and insufficient testing of other parts, making it impossible to determine lifespan. It also reduces testing efficiency, requires constant adjustment of the pump head position, increases time and difficulty, and is not conducive to large-scale testing. Utility Model Content

[0004] This utility model discloses a pump head testing device with material sorting and screening function, which aims to solve the technical problems of inaccurate test data due to unstable clamping during existing press pump head testing, large errors in flow and pressure data caused by pump head shaking or displacement, which cannot reflect performance, make it difficult to assess durability, reduce efficiency, require adjustment of pump head position, increase time and difficulty, and are not conducive to large-scale testing.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pump head testing device with material sorting and screening function, comprising a testing platform, wherein multiple equidistant circular holes are opened on the testing platform, and multiple connecting ring tubes are fixedly connected inside each circular hole. Each connecting ring tube contains a screening and fixing assembly, which includes a second drive motor. The power output shaft of the second drive motor is connected to a first bevel gear via a bearing transmission. A second bevel gear is movably connected to the outer side of the first bevel gear, and the first bevel gear meshes with the second bevel gear through a tooth groove. The inner side of the bevel gear two is fixedly connected to a rotating ring, the bottom end of the rotating ring is fixedly connected to an electric drive telescopic rod, the bottom end of the electric drive telescopic rod is fixedly connected to a base, the top end of the base is fixedly connected to a telescopic motor connecting frame, the inner side of the upper end of the telescopic motor connecting frame is fixedly connected to the outer side of the drive motor two, the electric drive telescopic rod is located at the front end of the drive motor two, the top end of the rotating ring is movably connected to multiple connecting rods, the top end of each connecting rod is movably connected to multiple connecting seats two, and the top end of each connecting seat two is fixedly connected to multiple arc-shaped clamping plates.

[0006] The system, equipped with a testing platform, connecting ring tube, and screening and fixing components, operates as follows: Before the material sorting and screening process, the electric drive telescopic rod rotates inward, causing the connecting rod on the rotating ring to rotate. This causes the arc-shaped clamping plate, fixedly connected to the connecting seat two above the connecting rod, to clamp the outer side of the pump head. Simultaneously, the drive motor two rotates the bevel gear one, which in turn rotates the rotating ring as a whole, moving the pump head to the corresponding position on the pressing plate. During this process, the screening and fixing components ensure stable pump head detection, prevent displacement and shaking, and ensure accurate pressing position and force, thereby improving the accuracy and reliability of the test results. Furthermore, the components fix the angle and direction, preventing angle changes from affecting the data, ensuring the consistency and comparability of the results, and simulating the actual installation state, making the testing environment more realistic and enhancing the practicality and reference value of the results.

[0007] In a preferred embodiment, a rotating rod is fixedly connected to the bottom of the detection platform, and a screening tube is fixedly connected to the bottom of each of the multiple connecting seats. A connecting plate is movably connected to the outer side of the rotating rod. The bottom of the screening tube contacts the top of the connecting plate. Symmetrical circular holes are provided on the connecting plate. A faulty pump head conveying pipe and a good pump head conveying pipe are fixedly connected to the inner side of each circular hole. A sorting platform is fixedly connected to the outer side of each faulty pump head conveying pipe and a good pump head conveying pipe. The top of the sorting platform is fixedly connected to the bottom of the connecting plate. The rotating rod is located inside the sorting platform. A linkage gear is fixedly connected to the bottom of the rotating rod. A drive gear is fixedly connected to the outer side of the linkage gear. The linkage gear and the drive gear mesh through a tooth groove. A drive motor is connected to the top of the drive gear through a bearing. A detection mechanism is movably connected to the bottom of both the linkage gear and the drive gear.

[0008] The system comprises a rotating rod, a screening tube, a connecting plate, a faulty pump head conveying tube, a good pump head conveying tube, a sorting table, a linkage gear, a drive gear, a drive motor, and a detection mechanism. After pump head inspection, the detection mechanism separates the good and bad pump heads. Then, the drive motor is activated to rotate the drive gear, which in turn rotates the linkage gear that meshes with the drive gear. This rotation drives the detection table to send the good and bad pump heads into the faulty pump head conveying tube and the good pump head conveying tube, respectively, thus achieving the sorting of pump heads.

[0009] In a preferred embodiment, a pressing assembly is provided above each of the plurality of screening and fixing components. The pressing assembly includes a third drive motor. The power output shaft of the third drive motor is connected to a threaded ring via a bearing drive. A helical gear ring is movably connected to the outer side of the threaded ring. The threaded ring and the helical gear ring are meshed through three-phase gear teeth. A base plate is fixedly connected to the bottom end of the helical gear ring. A symmetrical connecting seat is fixedly connected to the top end of the base plate. Each connecting seat has a through hole. The power output shaft of the third drive motor is rotatably connected inside one of the through holes. A connecting post is bolted to the opposite side of the symmetrical connecting seat. The threaded ring is located outside the connecting column, and an auxiliary sliding rod is fixedly connected to the top of the base plate. The auxiliary sliding rod is located in front of the connecting seat one on the side away from the drive motor three. A rotating screw is fixedly connected to the top of the helical gear ring. Sliding seats are movably connected to the outer sides of the rotating screw and the auxiliary sliding rod. A connecting rod is fixedly connected to the opposite side of the sliding seats. Symmetrical limiting plates are provided on the outer sides of the connecting column and the connecting column. The bottom end of the limiting plate is fixedly connected to the top end of the base plate. The limiting plates are all located inside the symmetrical connecting seat one. A pressing plate is fixedly connected to the outer side of the connecting rod. The pressing plate is located above the screening fixing component.

[0010] By incorporating a pressing assembly, during pump head testing, the drive motor rotates the threaded ring on the outer side of the connecting column. The helical gear ring on the outer side of the threaded ring rotates the lead screw. Simultaneously, the lead screw and the sliding seat on the outer side of the auxiliary sliding rod slide up and down. The pressing plate, fixedly connected to the sliding seat, slides up and down inside the limiting plate, repeatedly pressing the pump head. During this process, the pressing assembly repeatedly presses the pump head multiple times, allowing for comprehensive observation of performance under different pressing cycles, testing its stability, and assessing its durability. Furthermore, multiple sets of data more accurately reflect performance characteristics than single pressing data, reducing the influence of accidental factors and making the results more representative and convincing.

[0011] As can be seen from the above, the pump head testing device with material sorting and screening function provided by this utility model has a screening and fixing component that can ensure the stability of pump head testing, prevent displacement and shaking, make the pressing position and force accurate, improve the accuracy and reliability of the test results, fix the angle and direction, avoid the angle change affecting the data, ensure the consistency and comparability of the results, and simulate the actual installation state, making the testing environment more realistic, and enhancing the practicality and reference value of the results.

[0022] Reference Figure 1 and Figure 5In a preferred embodiment, a pressing component 8 is provided above each of the multiple screening and fixing components 11. The pressing component 8 includes a drive motor 801. The power output shaft of the drive motor 801 is connected to a threaded ring 803 via a bearing drive. A helical gear ring 804 is rotatably connected to the outer side of the threaded ring 803. The threaded ring 803 and the helical gear ring 804 are meshed by three-phase gear teeth. The bottom end of the helical gear ring 804 is bolted to a base plate 807. The top end of the base plate 807 is bolted to a symmetrical connecting seat 802. Each connecting seat 802 has a through hole. The power output shaft of the drive motor 801 is rotatably connected inside one of the through holes.

[0023] Working principle: Before the material sorting and screening process, the electric drive telescopic rod 1108 is started, which drives the connecting rod 1107 on the rotating ring 1106 to rotate inward. This causes the arc-shaped clamping plate 1110, which is fixedly connected to the connecting seat 1109 above the connecting rod 1107, to clamp the outside of the pump head. At the same time, the drive motor 1101 is started, which drives the bevel gear 1104 to rotate. Then, the bevel gear 1105, which meshes with the bevel gear 1104, drives the rotating ring 1106 to rotate as a whole, rotating the pump head to the position corresponding to the push plate 811. When the pump head is being tested, the drive motor 801 is started, which drives the threaded ring 803 on the outside of the connecting column 812 to rotate. The helical gear ring 804 on the side realizes the rotation of the lead screw 805. At the same time, the sliding seat 806 on the outside of the lead screw 805 and the auxiliary sliding rod 809 slides up and down. The push plate 811, which is fixedly connected to the sliding seat 806, slides up and down on the inside of the limiting plate 808, realizing the repeated pressing of the pump head by the push plate 811. After the pump head is tested, the good and bad pump heads are screened by the testing mechanism 7. Then, the drive motor 14 is started to drive the drive gear 13 to rotate. At the same time, the linkage gear 12, which meshes with the drive gear 13 through the tooth groove, rotates. Then, the testing table 1 is rotated to send the good and bad pump heads into the bad pump head delivery pipe 5 and the good pump head delivery pipe 6 respectively, realizing the screening of pump heads.
