Description

Technical Field

[0001] This utility model relates to the field of sealing test equipment technology, and in particular to a turbine pump end face sealing test device. Background Technology

[0002] The end face seal test of the turbopump verifies the reliability and performance parameters of the sealing structure to ensure stable fluid isolation under harsh conditions such as high-speed rotation and high pressure differential, and avoids media leakage, wear or failure.

[0003] The test requires the use of testing equipment to check whether the leakage of the sealing surface under rated pressure is lower than the design threshold, in order to prevent safety accidents caused by leakage of dangerous media such as fuel and oxidizer. However, most existing sealing test equipment adopts a single-port test mode, which cannot simultaneously test the sealing surfaces at both ends of the turbopump in parallel. This results in a long test cycle, which is difficult to meet the rapid verification requirements of mass production. In addition, the sealing structure needs to be frequently disassembled and replaced, which further prolongs the test process. Furthermore, the sealing components of existing devices are usually of fixed specifications, which are difficult to adapt to the port size differences of different turbopump models. When the test object is changed, the entire sealing module or even the test frame needs to be replaced, which not only increases the equipment cost. Utility Model Content

[0023] like Figure 2As shown, the output end of the top plate 7 extends through the top plate 7 to the area below the top plate 7 and is fixedly installed with a pressure head 17. The lower end face of the pressure head 17 has a spherical groove and a rubber pad is fixedly installed. The cooperation between the cylinder 9, the rubber seat 10, and the pressure head 17 can fix the turbine pump on the rubber seat 10, which is convenient for testing operations.

[0024] like Figures 2-6 As shown, the rubber seat 10 is made of rubber and has an air hole 15 inside. A pad 16 is fixedly installed at the bottom of the rubber seat 10. The bottom of the pad 16 is fixedly installed on the base plate 5, and a connector is fixedly installed at the bottom of the pad 16 and communicates with the cavity of the air hole 15. One end of the connector at the bottom of the pad 16 is also connected to an external air pump through an air pipe. The rubber seat 10 is designed with a conical structure to allow for the insertion and sealing of turbine pump ports of different sizes. The fixing frame 11 has first sliding grooves 18 on both sides. The vertical adjustment frame 12 has first sliders 19 fixedly installed on both sides. The first sliders 19 are slidably connected in one of the first sliding grooves 18. The vertical adjustment frame 12 has second sliding grooves 20 at the top and bottom. The horizontal adjustment block 13 has multiple shaft holes 22. A screw 23 is threadedly connected to the middle of the horizontal adjustment block 13. One end of the screw 23 is fixedly installed in the... The sealing plate 14 is equipped with a rotating block 24, and an operating handle is fixedly installed at the other end of the screw 23. The top and bottom of the horizontal adjusting block 13 are fixedly installed with second sliders 21, and the second sliders 21 are slidably connected in one of the second slide grooves 20. The horizontal adjusting block 13 is slidably connected in the vertical adjusting frame 12, and the vertical adjusting frame 12 is slidably connected in the fixed frame 11, so that the position of the sealing plate 14 can be arbitrarily adjusted. Multiple sealing gaskets 25 are fixedly installed on one side of the sealing plate 14. Multiple sealing gaskets 25 of different diameters can be adapted to turbine pump ports of different sizes. Multiple guide shafts 26 are fixedly installed on the side of the sealing plate 14 opposite to the sealing gaskets 25.

[0025] It should be noted that this utility model is a turbine pump end face sealing test device. During the test, one port of the turbine pump is placed above the rubber seat 10. At this time, the cylinder 9 on the top plate 7 is connected to an external air pump through an air pipe. The output end of the cylinder 9 pushes the pressure head 17 downward. The rubber pad at the lower end of the pressure head 17 presses against the top of the turbine pump, thereby completing the fixation of the turbine pump. Subsequently, the operating handle at one end of the screw 23 can be held and the horizontal adjusting block 13 can be adjusted horizontally within the vertical adjusting frame 12 by using the screw 23. Simultaneously, the vertical adjusting frame 12 slides vertically within the fixed frame 11 by the force of the horizontal adjusting block 13, thereby adjusting the sealing plate 14 to the test port side of the worm gear pump. At this time, the operating handle at one end of the screw 23 can be rotated to make the screw 23... 3. Rotate the screw 23 towards the turbine pump side within the vertical adjustment frame 12, thereby causing the rotating block 24 at the other end of the screw 23 to rotate in the rotating groove within the fixed seat 27. This causes the sealing plate 14 to move towards the test port side of the turbine pump, and the corresponding sealing gasket 25 on one side of the sealing plate 14 to engage with the test port of the turbine pump. The remaining large-diameter sealing gaskets 25 abut against the test port side of the turbine pump, fitting the end face through a simulated flange connection to form a sealing test interface. Subsequently, after both ends of the turbine pump are sealed by the rubber seat 10 and the sealing plate 14 respectively, the test medium is injected into the water tank 1. The main controller 2 controls the pressurization system to apply the rated pressure to the inside of the turbine pump through the rubber seat 10. At this time, observe whether the leakage between the sealing gasket 25 and the end face is lower than the design threshold.
