[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] Example 1, please refer to Figure 1 , 24. This utility model provides a technical solution: an electromagnetic pump flow testing device. Multiple sets of positioning components 2 are arranged in parallel on the top of a support frame 1. Each positioning component 2 includes a base plate 2.1 fixed to the top of the support frame 1, a pair of slotted blocks 2.2 fixed to the top surface of the base plate 2.1 and used to support the electromagnetic pump inlet and outlet nozzles, a transverse movement mechanism, an oil receiving component that moves with the transverse movement mechanism to engage with the ports of the electromagnetic pump inlet and outlet nozzles, and an electrical probe 2.4 that moves with the transverse movement mechanism to engage with the electromagnetic pump wiring port. The oil receiving component corresponding to the electromagnetic pump inlet nozzle is connected to an oil storage tank via a pipeline, and the electrical probe 2.4 is electrically connected to a power source. The transverse movement mechanism and the oil receiving component are configured in the following ways:

[0025] Oil receiving blocks 2.6 are fixed to the front and rear sides of the middle of the base plate 2.1. A pair of slot blocks 2.2 are provided on both sides of the oil receiving blocks 2.6. Clamping telescopic cylinders 2.9 are fixed horizontally at the middle of both ends of the base plate 2.1. Moving blocks 2.3 are fixedly fitted on the piston rod ends of the clamping telescopic cylinders 2.9. Oil receiving pipe heads 2.5 are fixedly fitted horizontally at the front and rear ends of the moving blocks 2.3 corresponding to the positions of the slot blocks 2.2. The electrical probe 2.4 is fixed to the inner side wall of the moving block 2.3. The top of the two side walls of the oil receiving block 2.6 are respectively provided with interfaces that match the liquid outlet of the electromagnetic pump. The oil receiving block 2.6 has a pipe with the top end connected to the interface and the bottom end connected to the outlet end placed in the mouth of the measuring cylinder 3.4.

[0026] The measuring mechanism 3 includes multiple measuring cylinders 3.4 vertically arranged within the inner cavity of the support frame 1. The outlet end of the pipeline connected to the oil receiving end corresponding to the oil outlet of the electromagnetic pump is placed inside the cylinder opening of the measuring cylinder 3.4. The measuring mechanism 3 also includes a pair of bearing seats 3.1 fixed to the inner cavity of the support frame 1, a shaft 3.2 with its front and rear ends respectively connected to the top of the bearing seat 3.1, and multiple retaining rings 3.3 uniformly fixed axially to the outer peripheral wall of the shaft 3.2. The middle portions of the measuring cylinders 3.4 are respectively fixedly fitted into the retaining rings 3.3. Furthermore, the front and rear ends of the shaft 3.2 are rotatably connected to the top of the bearing seat 3.1. A gear 3.5 is fixedly fitted at one end of the shaft 3.2. A fixing frame 3.6 extending laterally is fixed in the inner cavity of the support frame 1 corresponding to the position of the gear 3.5. A push-telescopic cylinder 3.7 is fixedly mounted laterally on the fixing frame 3.6. A rack 3.8 meshing with the gear 3.5 is fixed to the end of the piston rod of the push-telescopic cylinder 3.7.

[0027] The inner cavity of the support frame 1 is provided with a collection tank 4 located below the measuring mechanism 3, and a drain pipe head 4.1 is fitted onto the bottom of the side wall of the collection tank 4.

[0028] In summary, when testing the flow rate of the electromagnetic pump, first connect the outer port of the oil inlet pipe 2.5 to the oil storage tank via a flexible hose. Connect the outer end of the power probe 2.4 to the power supply via an electrical wire. Connect the bottom port of the oil inlet block 2.6 to the infusion line, with the bottom port of the infusion line positioned at the top of the corresponding measuring cylinder 3.4.

[0029] Place the inlet nozzle of the electromagnetic pump under test on the slot block 2.2 near the oil inlet head 2.5, and place the outlet nozzle on the slot block 2.2 near the oil inlet block 2.6. The slot block 2.2 has a U-shaped slot at the top center for placing the oil nozzle.

[0030] Subsequently, the piston rod of the clamping telescopic cylinder 2.9 is extended, and the piston rod drives the moving block 2.3 to move towards the electromagnetic pump under test until the oil receiving end 2.5 is connected to the port of the liquid inlet, and the power probe 2.4 is plugged into the wiring port of the electromagnetic pump. At the same time, the oil outlet of the electromagnetic pump is inserted into the interface on the top side wall of the oil receiving block 2.6.

[0031] Turn on the power supply switch of the power equipment to start the electromagnetic pump. The electromagnetic pump draws oil from the oil storage tank through the inlet nozzle, oil inlet head 2.5 and corresponding pipelines, and discharges the oil into the measuring cylinder 3.4 through the outlet nozzle, oil inlet block 2.6 and corresponding pipelines. After the electromagnetic pump has run for a fixed time, turn off the power supply switch of the power equipment. The flow rate of the electromagnetic pump can then be calculated from the amount of oil in the measuring cylinder 3.4.

[0032] After testing a set of electromagnetic pumps, the telescopic cylinder 3.7 performs the corresponding push-pull operation of the rack 3.8, so that the shaft 3.5 rotates through the meshing of the rack 3.8 and the gear 3.5, thereby pouring the oil in the measuring cylinder 3.4 into the collection tank 4. The oil collected in the collection tank 4 is discharged through the pipeline connected to the drain pipe head 4.1.

[0033] In addition, to ensure the smooth movement of the movable block 2.3 along with the piston rod of the clamping telescopic cylinder 2.9, guide blocks 2.8 are fixed on the top surface of the base plate 2.1 at positions corresponding to the outer sides of the front and rear ends of the movable block 2.3. The outer end of the oil inlet pipe head 2.5 is slidably sleeved on the guide block 2.8, and a support seat 2.7 is fixed on the top surface of the base plate 2.1, which slides laterally in contact with the electromagnetic pump terminal. That is, when the movable block 2.3 moves, the oil inlet pipe head 2.5 moves relative to the guide block 2.8, and the guide block 2.8 provides a guiding function.

[0034] After performing a flow test on the electromagnetic pump, the piston rod of the clamping telescopic cylinder 2.9 is retracted, which allows the oil inlet head 2.5 to be disconnected from the inlet nozzle, the oil inlet block 2.6 to be disconnected from the outlet nozzle, and the electrical probe 2.4 to be disconnected from the electrical port. This facilitates the removal of the tested electromagnetic pump and makes it easier to conduct flow tests on the next batch of electromagnetic pumps.

[0035] Example 2, please refer to Figure 1 , 3 4. The only difference between this embodiment and embodiment 1 is the arrangement of the transverse mechanism and the oil receiving component. In this embodiment, the transverse mechanism and the oil receiving component are arranged as follows:

[0036] U-shaped grooves 2.12 are fixed near both ends of the top surface of the base plate 2.1. A pair of retaining blocks 2.2 are provided on the front and rear sides of the U-shaped grooves 2.12. Guide rails 2.10 are fixed laterally on both sides of the top surface of the base plate 2.1, located on either side of the U-shaped grooves 2.12. Sliding blocks 2.11 are slidably mounted on the guide rails 2.10. Moving blocks 2.3 are fixed to the top surface of the sliding blocks 2.11. The front and rear ends of the moving blocks 2.3 are respectively fixedly fitted laterally at positions corresponding to the retaining blocks 2.2. The oil pipe head 2.5 and the electrical probe 2.4 are fixed on the outer movable block 2.3. A handle 2.13 is rotatably connected between the front and rear walls of the inner cavity of the U-shaped groove 2.12. The handle 2.13 is located on the upper and lower sides of the shaft connecting it to the U-shaped groove 2.12 and is rotatably connected to the connecting rod 2.14. The other end of the connecting rod 2.14 is rotatably connected to the middle of the corresponding movable block 2.3. A support seat 2.7 is fixed on the top surface of the base plate 2.1 and slides laterally with the electromagnetic pump terminal.

[0037] That is, when testing the flow rate of the electromagnetic pump, the inlet of the electromagnetic pump is placed on top of the outermost slot block 2.2 in each set of slot blocks 2.2, and the outlet is placed on top of the innermost slot block 2.2.

[0038] The outer end of the oil inlet pipe head 2.5 on the outer movable block 2.3 is connected to the oil storage tank via a hose, and the outer end of the power probe 2.4 is connected to the power supply via an electric wire; the output end of the pipeline sleeved on the port of the oil inlet pipe head 2.5 on the inner movable block 2.3 is placed at the top of the inner cavity of the corresponding measuring cylinder 3.4.

[0039] Then, the top of the handle 2.13 is swung, and the handle 2.13 pulls the moving block 2.3 towards the center via the connecting rod 2.14. The moving block 2.3 moves synchronously towards the center under the guidance of the slider 2.11 and the guide rail 2.10. This allows the outer oil inlet head 2.5 to connect with the inlet nozzle of the electromagnetic pump, and the inner oil inlet head 2.5 to connect with the outlet nozzle of the electromagnetic pump. At the same time, the electrical probe 2.4 is plugged into the wiring port of the electromagnetic pump.

[0040] Turn on the power supply switch of the power equipment to start the electromagnetic pump. The electromagnetic pump draws oil from the oil storage tank through the inlet nozzle, the outer oil inlet head 2.5 and the corresponding pipeline, and discharges the oil into the measuring cylinder 3.4 through the inner oil inlet head 2.5 and the corresponding pipeline. After the electromagnetic pump has run for a fixed time, turn off the power supply switch of the power equipment. The flow rate of the electromagnetic pump can then be calculated by the amount of oil in the measuring cylinder 3.4.

[0041] After performing a flow test on the electromagnetic pump, the handle can be reversed to disconnect the oil inlet 2.5 from the inlet and outlet nozzles, and the electrical probe 2.4 from the electrical port, so that the tested electromagnetic pump can be removed, thus facilitating the flow test of the next batch of electromagnetic pumps.
