Description

Technical Field

[0001] The invention relates to the technical field of plunger pumps, in particular to a plunger pump slipper pair testing tool and a testing process thereof. Background Art

[0002] The plunger pump is an important part of the aircraft. The axial pull-off force of the plunger pump shoe assembly is one of the indicators of the plunger pump quality. The plunger pump shoe assembly is characterized by a ball socket of the shoe and a ball head of the plunger connected by a rolling package, and has a small size. The axial pull-off force index is the maximum pulling force when the ball head of the plunger is pulled out of the ball socket of the shoe during the test. The test process is a process in which the shoe is gradually destroyed.

[0003] The outer dimensions of the plunger pump slipper assembly are small. In the absence of special tooling, the vise-type hard clamping method of the equipment is usually used to clamp the outer circle of the slipper and the plunger for testing. The outer dimensions of the plunger pump slipper assembly are small and difficult to operate, which poses a personal safety risk to personnel. The slipper and the plunger are not easy to be coaxial, and the tested pull-off force is not the axial pull-off force;

[0004] When the slipper and the plunger are in use, the angle between the plunger's ball head and the slipper's ball socket will change as the plunger and the swash plate rotate. However, the existing common testing method can only measure the maximum tension in a vertical direction, and cannot measure the maximum tension at multiple angles when the plunger's ball head falls out of the slipper's ball socket according to actual usage.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-7 The present invention provides a technical solution: a plunger pump slipper pair test fixture, comprising a test mechanism 1, a hydraulic tensioner 10 is installed on the inner wall of the bottom of the test mechanism 1, a plunger 11 is installed at the front end of the test mechanism 1, a ball head 12 is installed at the bottom end of the plunger 11, and a slipper 13 is arranged at the bottom of the ball head 12; and

[0038] A clamping assembly 2, which is mounted on the front end of the top of the testing mechanism 1 and is used to clamp and fix the plunger 11; and

[0039] A follow-up tension component 3, which is installed on the top of the hydraulic tensioner 10. The follow-up tension component 3 is used to apply tension to the angle adjustment component 4 through the hydraulic tensioner 10, and change the angle by following the angle change of the angle adjustment component 4;

[0040] An angle adjustment component 4, which is disposed at the top of the follower tension component 3 and is used to drive and adjust the angle between the sliding shoe 13 and the ball head 12; and

[0041] The rotating fixing component 5 is installed at the top of the angle adjustment component 4. The rotating fixing component 5 is used to fix the sliding shoe 13 and can slide between the sliding shoe 13 and the angle adjustment component 4 when the angle changes, so that the tension between the sliding shoe 13 and the plunger 11 is always kept vertical.

[0042] Furthermore, the clamping assembly 2 includes a servo motor 20, which is installed at the front end of the test mechanism 1. A worm 21 is provided at the output end of the servo motor 20, and the bottom end of the hydraulic tensioner 10 and the bottom inner wall of the test mechanism 1 are arranged to be vertically installed.

[0043] Furthermore, a fixed shaft 22 is installed at the front end of the testing mechanism 1, the outer wall of the fixed shaft 22 is sleeved with a rotating drum 23, the outer wall of the rotating drum 23 is sleeved with a worm gear 24, a side clamp 25 is installed at the bottom end of the rotating drum 23, an arc clamp 26 is installed at the bottom end of the side clamp 25, a plurality of anti-slip strips 27 are provided on the inner side of the arc clamp 26, and the plunger 11 is installed on the inner side of the side clamp 25.

[0044] Furthermore, the worm wheel 24 is meshed with the worm 21, the arc clamp 26 is set to be arc-shaped and fits the plunger 11, the rotating cylinder 23 is rotatably connected to the outer wall of the fixed shaft 22, and the outer wall of the arc clamp 26 is sleeved with a lock ring 14. In real-time use, the staff first extracts an installed sliding shoe 13 and plunger 11, and inserts the sliding shoe 13 horizontally into the inner wall of the base 50 in the rotating fixed component 5, so that the sliding shoe 13 is in the center of the base 50, and then places the plunger 11 in the arc-shaped clamp 2 in the clamping component 2. The staff then starts the servo motor 20 to drive the worm 21 to rotate the worm gear 24 meshing with it, and then the worm gear 24 drives the side clamp 25 and the arc clamp 26 to rotate toward the middle until the anti-slip strip 27 clamps the plunger 11. At this time, the staff puts the locking ring 14 on the outside of the arc clamp 26 and locks it to further fix the plunger 11. The anti-slip strip 27 made of hot-formed steel is to increase the friction to prevent the plunger 11 from slipping during the tensile test. After installation, the plunger 11 and the sliding shoe 13 are in a vertical state, and the staff starts to start the hydraulic tensioner 10, and pulls the ball socket of the sliding shoe 13 and the ball head 12 at the bottom of the plunger 11 downward through the following tension component 3, the angle adjustment component 4 and the rotation fixing component 5 until the ball head 12 at the bottom of the plunger 11 is separated from the ball socket of the sliding shoe 13. At this time, the staff records the maximum tension value of the hydraulic tensioner 10, which is the maximum tension value of the ball socket of the sliding shoe 13 and the ball head 12 at the bottom of the plunger 11, and When the clamping assembly 2 measures the maximum tension of the coaxial sliding shoe 13 and the plunger 11, the servo motor 1 20 is in the off state. At this time, since the side fixing plate 32 can slide inside the side slot 31, according to the principle that the clamping assembly 2 and the hydraulic tensioner 10 are in a vertical state, the tension is also vertical. Therefore, at this time, the sliding shoe 13 will follow the rotating fixing assembly 5 through the two sets of side fixing plates 32 to change the adaptive angle in the side slot 31, ensuring that the sliding shoe 13 and the plunger 11 are coaxially tested with the coaxial maximum tension;

[0045] Furthermore, the follower tension component 3 includes an arc plate 30, the front end and the back of the arc plate 30 are provided with side slots 31, the inner wall of the side slot 31 is movably connected to the side fixing plate 32, the top of the side fixing plate 32 is installed with a pull rod 33, the top of the arc plate 30 is set to an arc, the top of the arc plate 30 is installed with a rack 34, the side fixing plate 32 can slide in an arc on the inner wall of the side slot 31, the number of side fixing plates 32 and pull rods 33 is set to two groups, the angle adjustment component 4 includes an adjustment plate 40, side baffles 41 are installed on both sides of the adjustment plate 40, the bottom of the adjustment plate 40 is set to an arc, and the arc angle is the same as that of the top of the arc plate 30, a servo motor 42 is installed at the front end of the adjustment plate 40, a gear column 43 is installed at the output end of the servo motor 42, an adjustment column 44 is installed at the top of the adjustment plate 40, and the adjustment column 44 A sliding plate 45 is arranged at the top, a gear column 43 is meshedly connected with the rack 34, and a pull rod 33 is arranged above the adjustment plate 40 and on the inner side of the side baffle 41. In real-time use, when it is necessary to measure the maximum pulling force value of other angles between the ball socket of the sliding shoe 13 and the ball head 12 at the bottom end of the plunger 11, firstly, by starting the servo motor 2 42, the gear column 43 is driven to rotate the rack 34 meshedly connected with the top of the adjustment plate 40 below. At this time, the rack 34 drives the adjustment plate 40 to rotate, and the adjustment plate 40 drives the top side fixing plate 32 and the pull rod 33 to rotate together while rotating. At this time, the side fixing plate 32 follows the adjustment plate 40 to slide in an arc shape on the inner wall of the side slot 31. The side fixing plate 32 and the pull rod 33 have the function of pulling and limiting, and the pull rod 33 is always blocked on the inside by the side baffle 41 and will not slip off;

[0046] Furthermore, the rotating fixing assembly 5 includes a base 50, a track plate 51 is installed at the front end and the bottom of the back of the base 50, side pull plates 52 are installed on both sides of the top of the base 50, the sliding plate 45 is arranged on the inner wall of the track plate 51, the sliding plate 45 is slidably connected to the inner wall of the sliding plate 45, a side opening 53 is opened on one side of the side pull plate 52, a servo motor 3 54 is arranged on one side of the side pull plate 52, a rubber turntable 55 is installed on the output end of the servo motor 3 54, the rubber turntable 55 is arranged on the inner side of the side opening 53, the sliding shoe 13 is arranged on the inner side of the side pull plate 52, and the top two sides are blocked by the side pull plate 52, and the rubber turntable 55 is close to the sliding shoe 13. In real-time use, when the adjustment plate 40 is adjusted to the required angle, the angle of the base 50 of the side fixing plate 32 and the rotating fixing assembly 5 will also change accordingly, and drive the ball socket of the sliding shoe 13 and the ball head 12 at the bottom of the plunger 11 to change, which is also in line with actual use. When the angle of the base 50 changes, the sliding plate 45 at the top of the adjusting column 44 at the bottom will also slide in the track plate 51 at the bottom of the base 50. Since the angle changes, the distance will also change accordingly, so it is necessary for the track plate 51 at the bottom of the base 50 and the sliding plate 45 at the top of the adjusting column 44 to slide a certain distance to offset the rotation angle (such as Figure 6 and 7As shown), finally, the staff starts the hydraulic tensioner 10 to pull downward until the ball head 12 at the bottom of the bent plunger 11 is separated from the ball socket of the sliding shoe 13. At this time, the maximum pulling force value of the hydraulic tensioner 10 is recorded, which can be the maximum pulling force value of the ball head 12 at the bottom of the bent plunger 11 to separate from the ball socket of the sliding shoe 13;

[0047] When this angle is measured, the staff puts the other plungers 11 and the sliding shoes 13 into the rotating fixing assembly 5 and the clamping assembly 2 on the top of the angle adjustment assembly 4 with the adjusted angle, and fixes the plunger 11 and the sliding shoes 13 so that their rotation is the same as the previous group, but different (before, the staff will mark the same position of the plunger 11 and the sliding shoes 13). When measuring this group, the servo motor 3 54 is started to drive the rubber turntable 55 to rotate, and the sliding shoes 13 are driven to deflect a certain angle from the marked position. This can measure the maximum tension values ​​of the sliding shoes 13 and the ball head 12 at the bottom of the plunger 11 at different angles and different rotation degrees, so as to achieve a more practical use. The angles of the ball head 12 of the plunger 11 and the ball socket of the sliding shoes 13 will change with the rotation of the plunger 11 and the inclined plate, and the maximum tension values ​​of multiple rotation degrees, thereby improving the accuracy of the tensile test between the ball head 12 of the plunger 11 and the ball socket of the sliding shoes 13.

[0048] A plunger pump slipper pair testing process, the specific operation steps are as follows:

[0049] S1: Take out an installed sliding shoe 13 and plunger 11, insert the sliding shoe 13 horizontally into the inner wall of the base 50 in the rotating fixing assembly 5, so that the sliding shoe 13 is in the center of the base 50, and then place the plunger 11 in the middle of the arc clamp 26 in the clamping assembly 2, start the servo motor 20, drive the worm 21 to rotate the worm gear 24 meshing with it, and then the worm gear 24 drives the side clamp 25 and the arc clamp 26 to rotate toward the middle until the anti-slip strip 27 clamps the plunger 11, and then put the lock ring 14 on the outside of the arc clamp 26 and lock it to further fix the plunger 11;

[0050] S2: After installation, start the hydraulic tensioner 10, and pull the ball socket of the sliding shoe 13 and the ball head 12 at the bottom of the plunger 11 downward through the following tension component 3, the angle adjustment component 4 and the rotation fixing component 5 until the ball head 12 at the bottom of the plunger 11 is separated from the ball socket of the sliding shoe 13. At this time, record the maximum tension value of the hydraulic tensioner 10, which is the maximum tension value of the ball socket of the sliding shoe 13 and the ball head 12 at the bottom of the plunger 11;

[0051] S3: By starting the servo motor 2 42, the gear column 43 is driven to rotate the rack 34 meshing with the top of the adjustment plate 40 below. At this time, the rack 34 drives the adjustment plate 40 to rotate. When the adjustment plate 40 rotates, it drives the top side fixing plate 32 and the pull rod 33 to rotate together. At this time, the side fixing plate 32 follows the adjustment plate 40 to slide in an arc shape on the inner wall of the side slot 31, and the pull rod 33 is always blocked by the side baffle 41 on the inside and will not slip off;

[0052] S4: When the adjustment plate 40 is adjusted to the required angle, finally start the hydraulic tensioner 10 to pull downward until the ball head 12 at the bottom of the bent plunger 11 is separated from the ball socket of the sliding shoe 13. At this time, the maximum pulling force value of the hydraulic tensioner 10 is recorded, which is the maximum pulling force value of the ball head 12 at the bottom of the bent plunger 11 to separate from the ball socket of the sliding shoe 13.

A plunger pump slipper pair testing tool as claimed in claim 3, Features: The rubber turntable (55) is arranged on the inner side of the side opening (53), the sliding shoe (13) is arranged on the inner side of the side pull plate (52), and the top two sides are shielded by the side pull plate (52), and the rubber turntable (55) is closely attached to the sliding shoe (13).

5. A testing process using the plunger pump slipper pair testing tool as claimed in claim 4, Features: The specific steps are as follows: S1: Take out an installed sliding shoe (13) and plunger (11), insert the sliding shoe (13) transversely into the inner wall of the base (50) in the rotating fixing assembly (5), so that the sliding shoe (13) is located at the exact center of the base (50), and then place the plunger (11) in the middle of the arc clamp (26) in the clamping assembly (2), start the servo motor 1 (20), drive the worm (21) to rotate the worm gear (24) meshed with it, and then the worm gear (24) drives the side clamp (25) and the arc clamp (26) to rotate toward the middle until the anti-slip strip (27) clamps the plunger (11), and then put the locking ring (14) on the outside of the arc clamp (26) and lock it to further fix the plunger (11); S2: After installation, the hydraulic tensioner (10) is started, and the ball socket of the sliding shoe (13) and the ball head (12) at the bottom end of the plunger (11) are pulled downward by the following tension component (3), the angle adjustment component (4) and the rotation fixing component (5) until the ball head (12) at the bottom end of the plunger (11) is separated from the ball socket of the sliding shoe (13). At this time, the maximum tension value of the hydraulic tensioner (10) is recorded, which is the maximum tension value of the ball socket of the sliding shoe (13) and the ball head (12) at the bottom end of the plunger (11); S3: By starting the servo motor 2 (42), the gear column (43) is driven to rotate the rack (34) meshing with the top of the adjustment plate (40) below. At this time, the rack (34) drives the adjustment plate (40) to rotate. When the adjustment plate (40) rotates, it drives the top side fixing plate (32) and the pull rod (33) to rotate together. At this time, the side fixing plate (32) follows the adjustment plate (40) to slide in an arc shape on the inner wall of the side slot (31), and the pull rod (33) is always blocked by the side baffle (41) on the inside and will not slip off; S4: When the adjustment plate (40) is adjusted to the required angle, the hydraulic tensioner (10) is finally started to pull downward until the ball head (12) at the bottom end of the bent plunger (11) is separated from the ball socket of the sliding shoe (13). At this time, the maximum pulling force of the hydraulic tensioner (10) is recorded, which is the maximum pulling force value for the ball head (12) at the bottom end of the bent plunger (11) to separate from the ball socket of the sliding shoe (13).
