[0001] This invention relates to the field of water pump testing equipment, and more particularly to a centrifugal water pump testing line. Background Technology
[0002] A centrifugal water pump is a pump that uses the centrifugal force generated by the rotation of an impeller to transport liquids. The pump shaft drives the impeller to rotate at high speed, and the rotation of the impeller causes the water to undergo centrifugal motion. The water is thrown towards the edge of the impeller and flows into the pump's pressure pipeline through the flow channel of the volute.
[0003] Centrifugal water pumps need to be tested before leaving the factory. Currently, factory testing is generally done manually, which is inefficient, prone to errors and omissions, and requires a special drying process after testing, making the process cumbersome. Therefore, there is an urgent need for a centrifugal water pump testing line that can automatically perform factory testing and drying to overcome these shortcomings. Summary of the Invention

[0025] like Figures 1 to 7 As shown, the present invention provides a centrifugal water pump testing line 100 for performing factory testing on a centrifugal water pump 01, which has an outlet 011 and a wiring terminal 012.
[0026] The centrifugal water pump testing line 100 includes a material conveying line 10 and a water pump testing dryer 20. The material conveying line 10 transports centrifugal water pumps in a specific direction (set as the X direction in this embodiment). The water pump testing dryer 20 includes a gripping device 21, a water outlet pipe device 22, an electrical connector device 23, and a water tank 24. The material conveying line 10 has a testing position 011. The gripping device 21 and the electrical connector device 23 are respectively arranged opposite each other on both sides of the testing position 011. The water tank 24 is located below the testing position 011. One end of the water outlet pipe device 22 is provided with a connecting pipe 221. When the centrifugal water pump 01 is transported to the detection position 011 by the material conveyor line 10, the gripping device 21 removes the centrifugal water pump 01 and places it into the water tank 24. The connecting pipe 221 is inserted into the water outlet 011, and the electrical connector device 23 is connected to the terminal block 012. The centrifugal water pump 01 starts and pumps the water in the water tank 24 into the water outlet pipe device 22. The water outlet pipe device 22 detects the head and flow rate of the output water. In this invention, the centrifugal water pump detection line 100 includes the material conveyor line 10 and the water pump detection dryer 20. The material conveyor line 10 is used to transport the centrifugal water pump 01. The water pump detection dryer 20 includes the gripping device 21, the water outlet pipe device 22, the electrical connector device 23, and the water tank 24.
[0027] During testing, the gripping device 21 grips the centrifugal water pump of the lower logistics conveyor line 10 and places it into the water tank 24. Then, the connecting pipe 221 is inserted into the outlet 011 of the centrifugal water pump 01, and the electrical connector device 23 is connected to the terminal 012 of the centrifugal water pump. At this time, the centrifugal water pump is powered on. After the centrifugal water pump is started, the centrifugal water pump pumps the water in the water tank 24 into the outlet pipe device 22. The outlet pipe device 22 detects the head and flow rate of the output water.
[0028] As can be seen, the centrifugal water pump testing line 100 of the present invention can automatically perform online testing of centrifugal water pumps, realize automatic loading and unloading and performance testing (head, flow rate), with a high degree of automation and improved work efficiency.
[0029] like Figures 1 to 7As shown, the water outlet device 22 includes a connecting water pipe 222 and a head and flow rate detector 223. The head and flow rate detector 223 is installed on the connecting water pipe 222, and a connecting pipe 221 is located at one end of the connecting water pipe 222. The other end of the connecting water pipe 222 is connected to the water tank 24. During testing, the centrifugal water pump 01 pumps water into the connecting water pipe 222, and the head and flow rate detector 223 detects the head and flow rate of the pumped water. Afterward, the water flows back to the water tank 24 for recycling.
[0030] like Figures 1 to 7 As shown, the gripping device 21 is arranged to slide in the vertical direction. After the inspection is completed, the gripping device 21 grips the centrifugal water pump 01 and puts it back on the logistics conveyor line 10, which facilitates the handling of the centrifugal water pump 01.
[0031] like Figures 1 to 7 As shown, the gripping device 21 includes a gripping robot 211, a vertical drive device 212, a first slide rail 213, and a mounting base 214. The first slide rail 213 extends vertically. The mounting base 214 is slidably mounted on the first slide rail 213 and is mounted at the output end of the vertical drive device 212. The vertical drive device 212 drives the mounting base 214 to slide vertically, and the gripping robot 211 is mounted on the mounting base 214. Preferably, the vertical drive device 212 can use a combination of a motor and a lead screw and nut pair to drive the mounting base 214. Preferably, to better grip the centrifugal water pump, two gripping robots 211 are provided, one on the left and one on the right. The ends of the gripping robots 211 are provided with arc-shaped gripping parts. The two gripping robots 211 clamp the centrifugal water pump through the gripping parts provided thereon to grip the centrifugal water pump.
[0032] like Figures 1 to 8 As shown, the water outlet device 22 also includes a rotary actuator 224, which is installed on the connecting water pipe 222.

Preferably, to better drive the connecting pipe 221 to rotate, a gear 2211 is provided at one end of the connecting pipe 221, and the rotary actuator 224 drives the connecting pipe 221 to rotate in both directions through gear transmission.
[0033] like Figures 1 to 7 As shown, the water pump testing dryer 20 of the present invention also includes a second slide rail 25. The second slide rail 25 is disposed opposite to the first slide rail 213 on both sides of the testing position 011 of the logistics conveying line 10.

[0034] like Figures 1 to 7As shown, the water pump testing dryer 20 of the present invention also includes a water absorption and drying device 26. A three-way controller 27 is installed on the connecting water pipe 222. The water absorption and drying device 26 is connected to the connecting water pipe 222 through the three-way controller 27. When testing is performed, the three-way controller 27 disconnects the connection between the water absorption and drying device 26 and the connecting water pipe 222. After the testing is completed, the three-way controller 27 opens the connection between the water absorption and drying device 26 and the connecting water pipe 222. After the testing is completed, the water absorption and drying device 26 extracts the water remaining in the centrifugal water pump and dries the centrifugal water pump.
[0035] The water-absorbing drying device 26 can be used to dry the centrifugal water pump after testing, eliminating the need for additional drying procedures. Furthermore, by setting up a three-way controller 27, the connection between the water-absorbing drying device 26 and the connecting water pipe 222 can be controlled. During testing, water will not flow into the water-absorbing drying device 26, and after the test is completed, the water in the centrifugal water pump will flow into the water-absorbing drying device 26.
[0036] like Figures 1 to 7 As shown, the centrifugal water pump testing line 100 of the present invention also includes a defective product conveying line 30. A transfer position 012 is provided to the right of the testing position 011 on the material conveying line 10. The defective product conveying line 30 is located on one side of the transfer position 012 and is connected to the material conveying line 10. The conveying direction (X direction) of the material conveying line 10 is orthogonal to the conveying direction (Y direction) of the defective product conveying line 30. A reversing conveying device 40 is installed below the transfer position 012. After testing, centrifugal water pumps that pass the test continue to be conveyed along the X direction by the material conveying line 10, while centrifugal water pumps that fail the test are transported along the Y direction to the defective product conveying line 30 via the reversing conveying device 40.

The support plate 50 is roughly plate-shaped, with a circular support base 51 on top. The centrifugal water pump 01 is installed in the support base 51, providing stable support and ensuring more stable transport of the centrifugal water pump 01. To facilitate the detection of the centrifugal water pump 01 reaching the detection position 11, an infrared sensor 60 is installed on the side of the detection position 11.
[0038] The following is a brief description of the testing process of the centrifugal water pump testing line 100 of the present invention: The material conveyor line 10 transports the centrifugal water pump to the testing position 011. The gripping device 21 removes the centrifugal water pump 01 and places it into the water tank 24. The electrical connector device 23 disconnects the connection between the water pipe 222 and the water absorption and drying device 26. The rotary driver 224 drives the connecting pipe 221 to rotate, and the connecting pipe 221 is inserted into the water outlet 011. The electrical connector device 23 is connected to the terminal block 012. The centrifugal water pump is started, and the centrifugal water pump pumps water from the water tank 24 into the connecting water pipe 222. The head and flow rate detector 223 detects the head and flow rate of the output water. After the test, the gripping device 21 lifts the centrifugal water pump 01, the rotary driver 224 drives the connecting pipe 221 to rotate, the connecting pipe 221 exits the water outlet 011, and the electrical connector device 23 is disconnected from the terminal block 012. The logistics conveyor line 10 transports the tested centrifugal water pump 01 to the transfer position 012. According to the test results, if the centrifugal water pump is found to be qualified, it continues to the right. If the centrifugal water pump is found to be unqualified, it is transferred to the defective product conveyor line 30 through the reversing conveyor device 40.
