[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1 to 5 As shown, a high-pressure gas source system performance verification device of the utility model includes a test bench 1, a base support assembly, a test base 2, and a motor 3. The base support assembly is connected to the test bench 1, and the test base 2 and the motor 3 are fixedly connected to the base support assembly. The test base 2 includes a pneumatic clutch 21, a base wheel 22, and an input shaft 23. The output end of the motor 3 is provided with a motor wheel 31, and the motor wheel 31 is connected to the base wheel 22 through a conveyor belt 32. The pneumatic clutch 21 is connected to the base wheel 22. One end of the input shaft 23 is assembled in the pneumatic clutch 21, and the other end is aligned with the power input end of the high-pressure gas supply equipment 5 to be tested. During the test, the pneumatic clutch 21 is closed to connect the base wheel 22 and the input shaft 23 as a whole.

[0024] The full verification device is equipped with an independent power supply box and controller. The motor 3 runs after the required power is connected. The high-speed rotation of the small pulley of the motor 3 is transmitted to the large pulley connected to the test base 2. The central outer end of the large pulley is designed with a "normally open" pneumatic clutch 21 device. When the low-pressure gas source interface on the pneumatic clutch 21 is opened, the gas pressure immediately pushes the internal friction plate 27, thereby realizing the clutch engagement transmission. The large pulley drives the input shaft 23 in the test base 2 to rotate through the flat key. Both ends of the input shaft 23 are equipped with high-speed bearings 25, which can realize the high-speed rotation of the input shaft 23. The high-pressure pressure supply equipment 5 is equipped with a crankshaft, a connecting rod, a piston, and a cylinder body. One end of the piston is movably connected in the cylinder body, and the other end of the piston is movably connected to the crankshaft through a connecting rod. The input shaft 23 is connected to the crankshaft, driving the crankshaft to rotate together, thereby driving the piston to reciprocate in the cylinder body, pressurizing the gas entering the cylinder body and then outputting it to form high-pressure gas.

[0025] The base support assembly includes a base 41, a bracket 42, and a conversion plate 43. The base 41 is installed on the test bench 1. The bottom of the bracket 42 is fixedly connected after adjusting its position on the base 41. The top of the bracket 42 is provided with an inclined mounting surface. The conversion plate 43 is fixedly connected after adjusting its position on the mounting surface of the bracket 42. The test base 2 is fixedly connected to the conversion plate 43.

[0026] The mounting surface of the bracket 42 is provided with a plurality of strip holes, and the conversion plate 43 is provided with mounting holes. After adjusting the alignment positions of the mounting holes and the strip holes, the conversion plate 43 is fixed to the bracket 42 by fasteners.

[0027] During installation, the test bench 1 is assembled with the fixed base 41, the fixed base 41 is assembled with the base bracket 42, the base bracket 42 is assembled with the base conversion plate 43, the base conversion plate 43 is assembled with the test base 2, and then the motor 3 drives the test base 2 through the motor 3 pulley and belt to test the high-pressure air supply equipment 5.

[0028] The installation position of the test can be adjusted horizontally by adjusting the installation position of the bracket 42 and the base 41. The bracket 42 is designed to be fixedly installed through the reserved hole position of the pneumatic clutch 21 to limit the rotational freedom of the pneumatic clutch 21. The height and angle of the test base 2 can be adjusted by different conversion plates 43, different angles of the bracket 42, and the adjustment of the installation holes of the conversion plate 43, the test base 2, and the bracket 42.

[0029] like Figure 5 As shown, the test base 2 also includes a base housing 24, a bearing 25, and an oil seal 26. The base housing 24 is fixedly connected to the base support assembly.

The oil seal 26 is connected to both ends of the base housing 24 and seals the rotating shaft chamber.

[0030] During assembly, first connect one side of the bearing 25 to the input shaft 23, then install the other side of the bearing 25 in the base housing 24, so that the input shaft 23 is installed as a whole on the base housing 24, and then install the corresponding spring retaining ring, oil seal 26, end cover 28 and other sealing parts; after the base wheel 22 is installed on the pneumatic clutch 21, it is assembled with the input shaft 23 as a whole, and the pneumatic clutch 21 and the input shaft 23 are then fastened together by the end cover 28.

[0031] The pneumatic clutch 21 includes an electromagnetic control valve, a high-pressure gas interface, a high-pressure gas pipeline, and a friction plate 27. The friction plate 27 is arranged in the clutch. One end of the high-pressure gas interface is connected to the friction plate 27, and the other end of the high-pressure gas interface is connected to an external gas source through a high-pressure gas pipeline. The electromagnetic control valve is arranged on the high-pressure gas pipeline. During testing, high-pressure gas is introduced to press the friction plate 27 to close the pneumatic clutch 21.

[0033] The pneumatic clutch 21 is usually in the normally open state. When the pneumatic clutch 21 needs to work, the pneumatic clutch 21 switch is turned on, and the electronic control system controls the valve to drive the gas source to supply gas. The high-pressure gas presses the pneumatic friction plate 27 to close the pneumatic clutch 21. At this time, the base wheel 22 is connected to the input shaft 23 as a whole, and the drive input shaft 23 starts to work. When the output gas of the high-pressure pressure supply equipment 5 reaches the rated pressure value, the electronic control system receives the signal from the digital pressure sensor and automatically drives the solenoid valve to open, disconnects the clutch gas source, and the pneumatic clutch 21 returns to the normally open state. During the working process, if the pneumatic clutch 21 needs to be disconnected, the electronic control system switch can also be manually operated to disconnect the pneumatic clutch 21 and restore the normally open state.

[0034] The test base 2 also includes a base housing 24, one end of which is connected to the high-pressure air supply device 5.

The relief valve 65 and the throttle valve 66 are used to control the oil volume in the high-pressure oil pipe and the output flow rate. The oil pressure gauge 69 is used to monitor the pressure in the high-pressure oil pipe in real time, so that the operator can adjust the supply of lubricating oil according to the pressure value.
