Description

Technical Field

[0001] This utility model relates to the technical field of flow testing platforms, and in particular to a flow testing platform for a pumping system. Background Technology

[0002] In hydraulic grouting systems, it is necessary to test the performance of pumping equipment. Timely detection of problems can reduce subsequent maintenance costs and downtime, thus mitigating operational risks. Furthermore, testing helps engineers assess the impact of different operating conditions and modes on pumping performance, thereby optimizing equipment operating parameters. The testing process requires measuring data such as flow rate, pressure, vibration, temperature, noise, and lifespan of one or two pumps with different types and materials in the pumping system. Currently available testing equipment is relatively rudimentary, using simple storage tanks combined with various crisscrossing pipelines and equipment, resulting in a relatively chaotic structure that hinders systematic flow rate testing. Utility Model Content

[0003] This invention addresses the aforementioned problems by disclosing a pumping system flow rate testing platform. Employing a systematic flow rate testing method, it can simulate various actual operating conditions to test and evaluate the comprehensive performance of the pumping system. The platform can monitor multiple parameters, including flow rate, pressure, vibration, temperature, and noise, thereby helping engineers comprehensively assess the effectiveness and reliability of the pumping equipment.

[0004] The specific technical solution is as follows:

[0005] A pumping system flow rate test platform includes a first storage tank, a second storage tank, a first suction / discharge circuit, and a second suction / discharge circuit. The first and second storage tanks are connected by pipelines. The outlet and inlet of the first storage tank are respectively connected to the inlet and outlet of two pumps under test via two first suction / discharge circuits, forming a loop. The outlet of the first storage tank is connected to the inlet of the second pump under test via the second suction / discharge circuit, and the outlet of the second pump under test is connected to the inlet of both the first and second storage tanks via the second suction / discharge circuit, forming a loop. Each first suction / discharge circuit includes an inlet pipe and a return pipe. One end of water pipe 1 is connected to the inlet and outlet of pump 1 under test, respectively. The other ends of water inlet pipe 1 and water return pipe 1 are connected to the outlet and inlet of storage tank 1, respectively. The suction and discharge circuit 2 includes water inlet pipe 2 and water return pipe 2. One end of water inlet pipe 2 and water return pipe 2 are connected to the inlet and outlet of pump 2 under test, respectively. The other end of water inlet pipe 2 is connected to the outlet of storage tank 1. The other end of water return pipe 2 is connected to the inlet of storage tank 1 and storage tank 2, respectively, through return pipe 1 and return pipe 2. Each of water return pipe 1 and water return pipe 2 is equipped with a flow meter, a pressure gauge, and an accumulator, wherein the number of accumulators on water return pipe 2 is at least two.

[0006] Both the pump under test 1 and the pump under test 2 are equipped with a vibration sensor, a noise sensor, an oil tank temperature sensor, an oil tank level sensor, and an oil tank pressure sensor. The test platform also includes a monitoring room PLC module, which is electrically connected to the flow meter, pressure gauge, vibration sensor, noise sensor, oil tank temperature sensor, oil tank level sensor, and oil tank pressure sensor.

[0007] Furthermore, the outlet end of the first storage pool is connected to a water outlet pipe, one end of which is equipped with a butterfly valve, and the other end of which is connected to two water inlet pipes and one water inlet pipe.

[0008] Furthermore, one end of each return pipe in the two suction and discharge circuits is connected to a manifold, so that the two return pipes are connected to the inlet end of the storage tank through the manifold.

[0009] Furthermore, the inlet end of the first pump under test is connected to one end of the first water inlet pipe via a steel wire hose, and the outlet end of the first pump under test is connected to one end of the first recovery pipe via a high-pressure rubber hose.

[0010] Furthermore, the flow rate of the second pump under test is greater than that of the first pump under test, and the diameters of the second inlet pipe and the second return pipe are both greater than those of the first inlet pipe and the first return pipe.

[0011] Furthermore, an electric ball valve is provided on the first return pipe, and a manual ball valve is provided on the second return pipe. The electric ball valve is electrically connected to the PLC module in the monitoring room.

[0012] The beneficial effects of this utility model are reflected in:

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Please see the appendix Figure 1-6This embodiment provides a pumping system flow test platform, including a storage tank 1, a storage tank 2, a suction / discharge circuit 3, and a suction / discharge circuit 4. Storage tank 1 and storage tank 2 are connected by a pipeline. The outlet and inlet of storage tank 1 are connected to the inlet and outlet of two pumps 8 under test through two suction / discharge circuits 3, forming a loop. The outlet of storage tank 1 is connected to the inlet of pump 9 under test through suction / discharge circuit 4. The outlet of pump 9 under test is connected to the inlet of storage tank 1 and the inlet of storage tank 2 through suction / discharge circuit 4, forming a loop.

[0025] The suction and discharge circuit 3 includes an inlet pipe 31 and a return pipe 32. One end of the inlet pipe 31 and the return pipe 32 are respectively connected to the inlet and outlet of the pump under test 8. The other end of the inlet pipe 31 and the return pipe 32 are respectively connected to the outlet and inlet of the storage tank 1. The suction and discharge circuit 4 includes an inlet pipe 41 and a return pipe 42. One end of the inlet pipe 41 and the return pipe 42 are respectively connected to the inlet and outlet of the pump under test 9. The other end of the inlet pipe is connected to the outlet of the storage tank 1. The other end of the return pipe 42 is connected to the inlet of the storage tank 1 and the storage tank 2 via return pipe 43 and return pipe 44, respectively. Both return water pipe 1 (32) and return water pipe 2 (42) are equipped with a flow meter (7), a pressure gauge (6), and an accumulator (5). There are two accumulators (5) on return water pipe 2 (42), and a spare accumulator mounting base (51) is reserved on the return water pipe. Two accumulators (5) are set in the suction and discharge circuit 2 (4) to avoid insufficient pressure release when a single accumulator (5) is used. By increasing the number of accumulators (5) in the pipeline, the magnitude of the compensation pipeline pressure can be better tested.

[0026] Both pump 8 and pump 9 under test are equipped with vibration and noise sensors, respectively. Their hydraulic tanks are equipped with tank temperature, tank level, and tank pressure sensors, respectively. Storage tanks 1 and 2 are also equipped with storage tank level sensors. The test platform also includes a monitoring room PLC module 10, which is electrically connected to the flow meter 7, pressure gauge 6, vibration sensor, noise sensor, tank temperature sensor, tank level sensor, tank pressure sensor, and storage tank level sensor. This allows both circuits to be monitored and controlled by the monitoring room PLC module 10. After receiving relevant data, the PLC module can project it onto a large screen in the monitoring room for real-time viewing via an industrial control computer. When the values ​​of the aforementioned sensors and instruments suddenly exceed limits or break through alarm settings, the monitoring room control system will immediately stop the equipment to protect it. Monitoring equipment can be deployed around the test platform equipment, and the data can be viewed at any time using the industrial control system. Furthermore, the testing platform has remote functionality, allowing users to log in to the system anytime, anywhere to view the current operating status of the equipment, the current camera feed, and remotely start and stop the equipment.

[0027] In this embodiment, the outlet end of the storage tank 1 is connected to a water outlet pipe, one end of which is equipped with a butterfly valve, and the other end of which is connected to two water inlet pipes 31 and one water inlet pipe 41.

[0028] In this embodiment, one end of each return pipe 43 in the two suction and discharge circuits 3 is connected to a collector pipe 12, so that the flow of the two return pipes 43 is concentrated through the collector pipe 12 and connected to the inlet end of the storage tank 1.

[0029] In this embodiment, the inlet end of the pump under test 8 is connected to one end of the water inlet pipe 31 through a steel wire hose 33, and the outlet end of the pump under test 8 is connected to one end of the recovery pipe 1 through a high-pressure hose 34.

[0030] In this embodiment, since the suction and discharge circuit 2 4 is mainly used to study and test how to reduce and eliminate the water hammer effect caused by the reversal of the pump under test 2 9, the suction and discharge ports of the pump under test 2 9 are relatively large, while the suction and discharge ports of the pump under test 1 8 are relatively small. This makes the flow rate of the pump under test 2 9 greater than that of the pump under test 1 8. In addition, the diameters of the manifold 12, the inlet pipe 2 41, and the return pipe 2 42 are all greater than the diameters of the inlet pipe 1 31 and the return pipe 1 32. This makes the upper limit of the system pressure of the suction and discharge circuit 2 4 greater than the upper limit of the system pressure of the suction and discharge circuit 1 3.

[0031] In this embodiment, an electric ball valve 431 is installed on the first return pipe 43, and a manual ball valve 441 is installed on the second return pipe 44. The electric ball valve 431 is electrically connected to the PLC module 10 in the monitoring room. The electric ball valve 431 and the manual ball valve 441 are used to control the system pressure of the second suction and discharge circuit 4. Using the manual ball valve 441 can reduce costs, and when personnel are at the equipment site, they can quickly control the pipeline pressure through the manual ball valve 441 without having to go to the monitoring room for control.

[0032] like Figure 5 As shown, the operating process of the suction and discharge circuit 3 is as follows: Two pumps under test 8 draw liquid material through a low-pressure inlet pipe 31 and a transparent steel wire hose 33 to the suction port. The material is then pumped out from the discharge port by the pumps under test 8, passing sequentially through a high-pressure hose 34, an accumulator 5, a flow meter 7, and a pressure gauge 6 before flowing back into the storage tank 1 and circulating in this manner. This allows for the testing of the lifespan and related data of two pumps with different types and materials of components.

[0033] like Figure 6As shown, the operating process of the suction and discharge loop 24 is as follows: Pump 29 under test draws liquid material through the low-pressure inlet pipe 241 to the suction port. The material is then pumped out from the outlet by pump 29 under test. The material passes through two accumulators 5 and a pressure gauge 6 before flowing into the storage tank and circulating in this manner. This tests how to reduce or eliminate the water hammer effect caused by the reversal of pump 29 under test, thereby mitigating pipeline damage caused by water hammer.

[0034] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
