[0024] As Figs. 1-2The hydrogen engine lubricating oil rapid evaluation simulation device shown in the application comprises a container 2, a stirrer 4, an oil pump 9, a controllable high-temperature heater 7, a copper alloy catalytic metal strip 14, and an oil temperature sensor 13. The upper part of the container 2 is provided with an oil inlet, the oil temperature sensor 13, and the copper alloy catalytic metal strip 14. The bottom is provided with the stirrer 4 and an oil outlet valve 11. The inlet of the oil pump 9 is connected with an oil conveying pipe 10. The other end of the oil conveying pipe 10 is connected with the container 2. The outlet of the oil pump 9 is connected with an oil inlet pipe 8. The other end of the oil inlet pipe 8 is connected with the inlet of the controllable high-temperature heater 7. The outlet of the controllable high-temperature heater 7 is connected with the upper part of the container 2 through an oil outlet pipe 5. In this way, after the oil pump 9 is started, the oil circulates in the oil conveying pipe 10, the oil pump 9, the oil inlet pipe 8, the controllable high-temperature heater 7, the oil outlet pipe 5, and the container 2. The improvement lies in that a controllable flow dripping pipe 12 is further arranged on the upper part of the container 2, which is used to simulate the environment in which a large amount of moisture is generated during the actual operation of the hydrogen engine. Specifically, the oil inlet is provided with an oil inlet cover 1. Preferably, the controllable flow dripping pipe 12 comprises a pipe body and a flow valve. The pipe body is fixed on the container 2 and located directly above the stirrer 4. The lower end of the pipe body extends below the oil liquid level in the container 2. The upper part of the pipe body is provided with the flow valve. More specifically, the inner wall of the container 2 is provided with a scale. A welding joint of the oil conveying pipe is welded at a position 10 cm below the scale and connected with the oil conveying pipe 10.

[0025] Preferably, the dripping pipe 17 comprises a tapered glass pipe 16 and a rubber head 15. The tapered glass pipe 16 is small at the lower end and large at the upper end. The upper part of the tapered glass pipe 16 is provided with the rubber head 15. The oil inlet cover 1 is provided with a perforation for assembling the dripping pipe 17. The diameter of the perforation is equal to the outer diameter of the middle part of the tapered glass pipe 16. That is, the diameter of the perforation is between the outer diameter of the upper end and the outer diameter of the lower end of the tapered glass pipe, so that the middle part of the tapered glass pipe 16 is clamped on the oil inlet cover 1 and cannot fall into the container, serving as a temporary storage for the dripping pipe 17 during the test. In a more preferred embodiment, the perforation is surrounded by a gasket to protect the tapered glass pipe 16.

[0026] In other embodiments, the gasket 18 is an annular sheet provided with a central hole 19. The diameter of the central hole 19 is greater than the diameter of the lower end of the tapered glass pipe 16. The gasket 18 is foam cotton. The good elasticity of the foam cotton clamps the dripping pipe 17 in position, so that the lower end of the dripping pipe 17 is located above the oil liquid level. When it is necessary to collect the oil sample, the dripping pipe 17 is pressed downward to extrude the gasket, so that the lower end of the dripping pipe 17 extends below the oil liquid level, thereby enabling the sample to be collected.

According to actual needs, the lubricating oil in the lubricating oil container 2 is sampled at any time, the water content of the oil sample is detected according to the oil sample, water is added into the container in time, and when the emulsification degree and the oil temperature of the oil sample reach target values, the operation is stopped. Subsequently, the emulsified and aged lubricating oil can be subjected to physical and chemical detection and friction and wear test, so as to fully evaluate the influence degree of different emulsification degrees and high-temperature aging on the performance of the lubricating oil.

[0028] The controlled high-temperature heater 7 simulates the local high-temperature environment of the piston and other parts of the engine, and is linked with the oil temperature sensor 13 to control, so that the lubricating oil container 2 can simulate the relatively stable temperature environment in the oil sump of the engine. Preferably, the controlled high-temperature heater 7 comprises a heater and a metal oil pipe 6, two ends of the metal oil pipe 6 are connected with the oil outlet pipe 5 and the oil inlet pipe 8 respectively, and the heater is used to heat the metal oil pipe 6.

The stirrer 4 is arranged at the bottom of the lubricating oil container 2, which can adjust the stirring rate and ensure that the water and the lubricating oil are fully stirred. The lubricating oil container 2 is further provided with an oil adding port cover 1 at the top, which is used to add the test lubricating oil into the container and sample the lubricating oil. The controlled flow water dripping pipe 12 is used to add water in different proportions into the container to be stirred and emulsified with the lubricating oil according to test requirements, and the dripping flow rate can be adjusted according to needs. The oil pump 9 inputs the fully stirred and emulsified lubricating oil into the controlled high-temperature heater 7 through the oil delivery pipe 10 and the oil inlet pipe 8 to be subjected to high-temperature heating, so as to simulate the lubricating oil flowing through the high-temperature area of the piston in actual operation of the engine. The controlled high-temperature heater 7 is adjusted according to the piston temperature in actual operation of the engine, and the built-in metal oil pipe 6 can be detached for cleaning.

[0030] Preferably, the device further comprises an oil return pipe 3, the oil return pipe 3 is installed on the upper part of the container 2, the upper end of the oil return pipe 3 is connected with the oil outlet pipe 5, and the lower end of the oil return pipe 3 is communicated with the container 2.
