In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0019] The technical solution adopted by this invention to solve its technical problem is: like Figure 1 , Figure 3 , Figure 7 and Figure 11 As shown in the figure, some embodiments of the present invention disclose an offline performance testing device for auxiliary pump sets of nuclear power diesel engine systems. This device includes a pump 10, a drive module 20, a cooling water medium module 30, a lubricating oil medium module 40, and a fuel medium module 50. The cooling water medium module 30, lubricating oil medium module 40, and fuel medium module 50 each store a medium. The pump 10 is mounted on the drive module 20 and can selectively connect to one of the cooling water medium module 30, lubricating oil medium module 40, and fuel medium module 50. Driven by the drive module 20, the pump 10 can selectively output and input the medium from one of these modules, allowing for medium exchange and circulation. This enables performance testing and the acquisition of parameters such as flow rate, pressure, and sealing performance of the pump 10. This equipment is used for spare parts acceptance testing, performance re-evaluation, and fault analysis of airborne pumps in nuclear power emergency oil extraction machines.

[0020] In some embodiments, pump 10 may include pumps required for airborne pump sets such as cooling water pumps, lubricating oil pumps, and fuel pumps.

[0021] like Figure 1 and Figure 2 As shown, in some embodiments, the drive module 20 may include a frame 21, a motor 22, a gearbox 23, and a pressure testing assembly 24. The motor 22 is mounted on the frame 21, the gearbox 23 is connected to the output shaft of the motor 22, and the pump 10 is mounted on the gearbox 23. The motor 22 provides the rated speed input to the pump 10 through the output speed of the gearbox 23. The pressure testing assembly 24 is disposed on the frame 21 and is used to test whether the pump 10 leaks externally.

[0022] Continue to refer to Figure 1 and Figure 2 In some embodiments, the frame 21 may include a platform 211, a handle 212, first rollers 213, a stabilizing assembly 214, a bracket 215, a retaining ring 216, angle steel 217, and a first drain valve 218. The handle 212 is located on one side of the platform 211 to facilitate the movement of the drive module 20. Four first rollers 213 are provided and installed at the four corners of the bottom of the platform 211 for easy movement. The stabilizing assembly 214 is installed at the bottom of the platform 211 and is used when the drive module 20 is parked to prevent it from moving due to collisions. The bracket 215 is installed on the platform 211 to support the motor 22. The retaining ring 215 is located on one side of the bracket 215. Four angle steels 217 are provided and installed at the four edges of the platform 211; the angle steels 217 have an L-shaped structure and form a water storage cavity 210 between themselves and the edges of the platform 211, which can be used to store media; during testing, if the pump 10 leaks media, it can flow into the water storage cavity 210. The first drain valve 218 is installed at the bottom of one of the angle steels 217 to drain the medium in the water storage chamber 210.

[0023] Refer again Figure 1 and Figure 2In some embodiments, the pressure-pressurizing assembly 24 may include a pressure-pressurizing pump 241, an inlet quick-connect coupling 242, an outlet quick-connect coupling 243, and a handle 244. The pressure-pressurizing pump 241 is mounted on one side of the bracket 215. The inlet quick-connect coupling 242 and the outlet quick-connect coupling 243 are respectively mounted on the water inlet and outlet ends of the pressure-pressurizing pump 241. The inlet quick-connect coupling 242 can be selectively connected to one of the cooling water medium module 30, the lubricating oil medium module 40, and the fuel medium module 50 via a pipe. The outlet quick-connect coupling 243 is connected to the outlet of the pump 10 via a pipe. Using the high pressure generated by the pressure-pressurizing pump 241, the high-pressure medium is injected and fills the pump 10. The pressure is maintained for a period of time, and the presence of leaks and whether the pump 10 meets the required strength are determined by observing the pressure drop or directly inspecting the pump 10. The handle 244 is placed in the retaining ring 216 and is used when the pressure-pressurizing pump 241 is pressurizing.

[0024] Specific steps: S1, the outlet end of one of the cooling water medium module 30, lubricating oil medium module 40, and fuel medium module 50 is connected to the inlet quick connector 242 of the pressure pump 241 via a pipe; the outlet quick connector 243 of the pressure pump 241 is connected to the inlet end of the pump 10 via a pipe; the outlet end of the pump 10 is connected to the inlet end of one of the cooling water medium module 30, lubricating oil medium module 40, and fuel medium module 50 via a pipe. The cooling water medium module 30, lubricating oil medium module 40, one of the fuel medium module 50, the pressure pump 241, and the pump 10 form a circulation loop.

[0025] S2, the handle 244 is installed on the plunger of the pressure pump 241. When the plunger is lifted by the handle 244, the medium in one of the cooling water medium module 30, lubricating oil medium module 40 and fuel medium module 50 is input into the pressure pump 241 through the inlet quick connector 242. When the handle 244 is pressed down, the plunger outputs the medium from the outlet quick connector 243 into the pump 10. Then the medium in the pump 10 is output from the outlet end of the pump 10 back into one of the cooling water medium module 30, lubricating oil medium module 40 and fuel medium module 50.

[0026] S3, stop pressurizing pump 241, and stop injecting medium into pump 10.

[0027] S4. Carefully observe whether there is any medium flowing out from the pump 10 casing or other locations.

[0028] Refer again Figure 2In some embodiments, the stabilizing component 214 may include a connecting flange 2141, a lead screw 2142, a base support 2143, and an adjusting nut 2144. The connecting flange 2141 is mounted on the bottom of the frame 21, the lead screw 2142 is threaded onto the connecting flange 2141, the base support 2143 is mounted on the bottom of the lead screw 2142, and the adjusting nut 2144 is mounted on the lead screw 2142. Understandably, rotating the adjusting nut 2144 causes the lead screw 2142 to rotate. While rotating, the lead screw 2142 can rise and fall. When the drive module 20 is stationary, the lead screw 2142 causes the base support 2143 to move downwards to contact the ground for stability and to prevent accidental slippage.

[0029] The drive module 20 also includes a touch system, which comprises a control system and a data acquisition system. The control system can control the start / stop, speed, and direction of the motor 22. The data acquisition system can collect and edit the pump's performance parameters such as flow rate and pressure.

[0033] Refer again Figure 3 and Figure 4 Furthermore, a first level gauge 316 is installed on one side of the first tank 311 to measure and observe the liquid level of the medium inside the first tank 311. A first heater blockage plate 317 is installed on one side of the first tank 311. When heating the medium inside the first tank 311, the first heater blockage plate 317 is removed and the heating device is inserted into the first tank 311 to heat the medium. A first drain valve 318 is installed at the bottom of one side of the first tank 311 for draining. A first circular oil level indicator 319 is installed at the top of one side of the first tank 311 to observe the liquid level of the medium. Two first cleaning covers 320 are provided, one on each side of the first tank 311. They can be removed after the experiment to clean the inside of the first tank 311. A first air filter 321 is installed on the first tank 311, allowing air to enter the first tank 311 and preventing dust from entering. A cooling water temperature transmitter 322 is installed on the first housing 311 to measure the temperature of the medium inside the first housing 311. Two first lifting lugs 323 are provided, located diagonally opposite each other in the first housing 311, for easy lifting and handling. Of course, three, four, or other quantities of first lifting lugs 323 can be provided. A first pressure-pressurizing quick-connect fitting 324 is located at the bottom of one side of the first housing 311 and is connected to the inlet quick-connect fitting 242 of the pressure-pressurizing pump 241 via a pipe.

[0034] Refer again Figure 4In some embodiments, the first liquid inlet assembly 33 may include a first liquid inlet pipe 331, at least one first pipe clamp 332, a first quick connector 333, a first return flange 334, and a first pressure-pressurized liquid inlet quick connector 335. The first liquid inlet pipe 331 is mounted on the first housing 311 via at least one first pipe clamp 332. A first quick connector 333 is installed at the inlet end of the first liquid inlet pipe 331, and the first quick connector 333 can be connected to the outlet end of the pump 10 via a pipe. The outlet end of the first liquid inlet pipe 331 is inserted into the first liquid inlet chamber 3111 of the first housing 311 via the first return flange 334. The medium discharged from the pump 10 enters the first liquid inlet chamber 3111 of the first housing 311 through the pipe and the first liquid inlet pipe 331. The first pressure-pressurized liquid inlet quick connector 335 is mounted on the first liquid inlet pipe 331 and is connected to the outlet end of the pump 10 via a pipe.

[0035] like Figure 4 and Figure 5 As shown, in some embodiments, the first liquid outlet assembly 34 may include a first liquid outlet pipe 341 and a first ball valve 342. The first liquid outlet pipe 341 connects to the first liquid outlet chamber 3112 of the first housing 311, and the first ball valve 342 is disposed on the first liquid outlet pipe 341. Understandably, the first liquid outlet pipe 341 is connected to the inlet end of the pump 10 via a pipe, and the medium in the first liquid outlet chamber 3112 of the first housing 311 enters the pump 10 through the first liquid outlet pipe 341 and the pipe. The first ball valve 342 is used to control the flow of the first liquid outlet pipe 341 and to control the flow of the medium between the first housing 311 and the pump 10.

[0036] Continue to refer to Figure 5 In some embodiments, the first detection and pressure regulating assembly 35 may include a first pressure sensor 351, a first pipeline temperature transmitter 352, a first pressure regulating valve 353, a first main flow meter 354, and a first auxiliary flow meter 355. The first pressure sensor 351, the first pipeline temperature transmitter 352, the first pressure regulating valve 353, the first main flow meter 354, and the first auxiliary flow meter 355 are sequentially installed on the first outlet pipe 341 from the inlet end to the outlet end.

[0037] Understandably, the first pressure sensor 351 is used to detect the pressure of the medium at the outlet of pump 10 (the inlet end of the first outlet pipe 341). The first pipeline temperature transmitter 352 is used to detect the temperature of the medium at the outlet of pump 10. The first pressure regulating valve 353 is used to regulate the pressure at the outlet of pump 10. The first main flow meter 354 and the first auxiliary flow meter 355 are used to detect the flow rate of the medium at different locations within the first outlet pipe 341. On one hand, one of the first main flow meter 354 and the first auxiliary flow meter 355 is located near the first pressure regulating valve 353 to detect the flow rate after pressure regulation by the first pressure regulating valve 353; the other is located near the outlet end of the first outlet pipe 341 to detect the flow rate at the outlet end of the first outlet pipe 341. On the other hand, the first main flow meter 354 and the first auxiliary flow meter 355 have different measurement ranges; the first main flow meter 354 is used to measure large flow rates, and the first auxiliary flow meter 355 is used to measure small flow rates.

[0039] The pump 10 (which is the cooling water pump of the diesel engine on-board pump set), drive module 20, and cooling water medium module 30 were tested together. To test for external leakage in pump 10, assemble pump 10, the pressure-pressurizing assembly 24 of drive module 20, and cooling water medium module 30: the first pressure-pressurizing outlet quick connector 324 of cooling water medium tank 31 is connected to the inlet quick connector 242 of pressure-pressurizing pump 241 via a pipe; the outlet quick connector 243 of pressure-pressurizing pump 241 is connected to the inlet of pump 10 via a pipe; the outlet of pump 10 is connected to the first pressure-pressurizing inlet quick connector 335 of first inlet assembly 33 via a pipe. Start pressure-pressurizing pump 241 to deliver the medium in cooling water medium tank 31 to pump 10, and the medium entering pump 10 is then delivered to cooling water medium tank 31. During this process, observe whether there is any external leakage in the pump 10 housing or other locations.

[0040] After eliminating external leakage, the pump 10, the gearbox 23 of the drive module 20, and the cooling water medium module 30 are assembled: the pump 10 is connected to the gearbox 23 via a coupling, and the first quick connector 333 of the first inlet assembly 33 is connected to the outlet end of the pump 10 via a pipe; the first outlet pipe 341 of the first outlet assembly 34 is connected to the inlet end of the pump 10 via a pipe. The starter motor 22 drives the gearbox 23 to drive the pump 10, which draws the medium from the cooling water medium tank 31 and then delivers it back to the cooling water medium tank 31 through the first outlet pipe 341. When the medium passes through the first outlet pipe 341, the pressure of the first pressure regulating valve 353 is adjusted, and the first main flow meter 354 and the first auxiliary flow meter 355 detect the flow rate in the first outlet pipe 341 to obtain the flow rate of the pump 10 outlet under different pressures. The pressure value of the first pressure regulating valve 353, and the flow values ​​detected by the first main flow meter 354 and the first auxiliary flow meter 355 are transmitted to the data acquisition system of the touch control system through the first terminal box 36. The data acquisition system collects the outlet pressure and flow of pump 10 to obtain the performance curve of pump 10. After the performance curve of pump 10 is completed, it is compared with the rated performance curve to determine whether pump 10 meets the usage requirements of emergency diesel engine.

The second inlet assembly 43 is connected to the top of the lubricating oil medium tank 41 and is connected to the outlet end of the pump 10 via a pipe. The second outlet assembly 44 is located at the bottom of one side of the lubricating oil medium tank 41 and is connected to the inlet end of the pump 10 via a pipe.

It can detect and eliminate potential performance defects of auxiliary pumps in advance, reduce the extension of whole machine testing time caused by auxiliary pump maintenance, improve the operational reliability of diesel engines, reduce maintenance costs, and prevent huge economic losses caused by the unavailability of emergency diesel engine auxiliary pump sets.
