Description

[0002] Reciprocating pumps include piston pumps, metering pumps, and diaphragm pumps, collectively known as reciprocating pumps. They are a type of positive displacement pump with wide applications. Reciprocating pumps are conveying machines that directly provide energy to liquids in the form of pressure energy through the reciprocating motion of a piston. Based on the driving method, reciprocating pumps are divided into two main categories: motorized pumps (driven by electric motors) and direct-acting pumps (driven by steam, gas, or liquid). Furthermore, the casing of a reciprocating pump requires grinding during manufacturing.

[0003] In existing reciprocating pumps, the crosshead's reciprocating motion can easily cause oil and air to accumulate inside the cavity, increasing resistance and reducing efficiency. Dry friction is also easily generated during the crosshead's reciprocating movement, leading to rapid temperature rise, accelerated wear, and reduced service life. Existing grinding devices have poor grinding effects and cannot handle the dust generated during grinding. To address these issues, the inventor proposes a reciprocating pump and processing device with a shock-resistant and wear-resistant crosshead bushing structure. Summary of the Invention

The new bushing facilitates more thorough lubrication and less wear between the new bushing and the embedded crosshead, extending service life; the embedded crosshead allows oil and gas to flow freely from both sides without blockage, thereby reducing motion resistance and improving the mechanical efficiency of the entire reciprocating pump.

[0012] 2.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example: Figure 1-16 As shown, the present invention provides a reciprocating pump with a shock-resistant and wear-resistant crosshead bushing structure, including a housing 100, a crankshaft 200 is provided on one side inside the housing 100, a plurality of connecting rods 300 are mounted on the surface of the crankshaft 200, and an embedded crosshead 700 is rotatably provided on the connecting rod 300 through a pin 400. The embedded crosshead 700 is slidably disposed inside a novel bushing 500, and a piston rod 600 is fixedly provided on one side of the embedded crosshead 700.

[0034] The inner wall of the new bushing 500 is provided with multiple spiral semi-circular oil grooves 501, and the two ends of the new bushing 500 are symmetrically fixed with bosses 502.

[0035] By adopting the above technical solution, a spiral semi-circular oil groove 501 is added to the inner wall of the new bushing 500, which makes lubrication more sufficient and reduces the wear between the embedded crosshead 700 and the new bushing 500, thereby extending the service life. At the same time, bosses 502 are added to both ends of the new bushing 500 to ensure that the new bushing 500 is firmly fixed and does not fall off when the embedded crosshead 700 reciprocates within the new bushing 500.

[0036] The inlaid crosshead 700 has symmetrical shapes on both sides set as a plane.

[0037] By adopting the above technical solution and through the planar setting, during the reciprocating motion of the embedded crosshead 700, oil and gas can flow freely from both sides without obstruction, thus reducing motion resistance and improving the mechanical efficiency of the entire reciprocating pump.

[0038] A reciprocating pump processing device with a shock-resistant and wear-resistant crosshead bushing structure includes a base plate 1. A grinding mechanism 2 is provided at one end of the top of the base plate 1. A placement mechanism 3 is provided on one side of the grinding mechanism 2. A transmission mechanism 4 is provided on one side of the placement mechanism 3. A dust removal mechanism 5 is provided at the other end of the top of the base plate 1. The dust removal mechanism 5 is connected to the transmission mechanism 4. A limiting mechanism 6 is provided on the outer ring of the top of the base plate 1. The grinding mechanism 2 is connected to the limiting mechanism 6.

[0039] By adopting the above technical solution, the grinding mechanism 2 facilitates the grinding operation of the reciprocating pump housing, the placement mechanism 3 facilitates the placement and rotation of the reciprocating pump housing, the transmission mechanism 4 facilitates the rotation of the dust removal mechanism 5 to remove the powder and dust generated during the grinding process, and the limiting mechanism 6 facilitates the limiting of the reciprocating pump housing.

[0040] The grinding mechanism 2 includes a mounting plate 21 and a mounting ring 22. A grinding motor 23 is mounted on one side of the mounting plate 21. An outer rod 25 is fixedly mounted on the output end of the grinding motor 23 via a first rotating shaft 24. A limit groove is opened at one end of the outer rod 25, and an inner rod 26 is slidably mounted in the limit groove. A grinding brush 27 is fixedly mounted on one end of the inner rod 26. A round block 28 is fixedly mounted on the surface of the inner rod 26. The outer wall of the round block 28 is rotatably engaged with the inner wall of the mounting ring 22. A first vertical plate 29 is rotatably mounted on one end of the first rotating shaft 24. An electric push rod 210 is mounted on one side of the first vertical plate 29. A vertical block 211 is fixedly mounted on the output end of the electric push rod 210. The bottom of the vertical block 211 is fixedly engaged with the top of the mounting ring 22.

[0041] By adopting the above technical solution, when it is necessary to polish the outer shell of the reciprocating pump, the polishing motor 23 is started to drive the first rotating shaft 24, the outer rod 25 and the inner rod 26 to rotate, which in turn drives the polishing brush 27 to rotate. At the same time, the round block 28 rotates inside the mounting ring 22, and the electric push rod 210 is started to extend it, which drives the inner rod 26 to slide along the inner wall of the outer rod 25 and approach the outer shell to perform the polishing operation on the outer shell.

[0042] The placement mechanism 3 includes a second vertical plate 31, a third rotating shaft 32, a sleeve 33, a fourth rotating shaft 34, and a placement tray 35. The bottoms of the second vertical plate 31 and the mounting plate 21 are fixedly fitted to one end of the top of the base plate 1. Two horizontal plates 36 are fixedly installed on one side of the second vertical plate 31, and a second rotating shaft 37 is rotatably connected between the two horizontal plates 36. Two first pulleys 38 are installed on one side of the second rotating shaft 37, and the two first pulleys 38 are connected by a first conveyor belt 39. One first pulley 38 is mounted on the second rotating shaft 37, and the other first pulley 38 is mounted on the third rotating shaft 32. Two bevel gears 310 are provided at the top. One bevel gear 310 is fitted onto the top of the third rotating shaft 32, and the other bevel gear 310 is fitted onto the first rotating shaft 24. A first spur gear 311 is fitted onto the surface of the second rotating shaft 37. A second spur gear 312 is meshed on one side of the first spur gear 311. The second spur gear 312 is fitted onto the sleeve 33. The inner wall of the sleeve 33 is rotatably engaged with the surface of the fourth rotating shaft 34. A placement disk 35 is fixedly provided at the top of the fourth rotating shaft 34. A fixing ring 313 is rotatably provided on the bottom outer ring of the placement disk 35. Support columns 314 are fixedly provided at the bottom corners of the fixing ring 313.

[0043] By adopting the above technical solution, when preparing to polish the housing of the reciprocating pump, the housing is placed at the top center of the placement plate 35, and the housing is limited by the limiting mechanism 6. When the first rotating shaft 24 rotates, it drives the bevel gear 310 to rotate, which in turn drives the third rotating shaft 32 and the first pulley 38 to rotate, which in turn drives the first spur gear 311 and the second spur gear 312 to rotate, so as to provide power for the rotation of the placement plate 35.

[0044] A rotating disk 315 is fixedly installed at the center of the fourth rotating shaft 34. A circular groove 316 is opened at the center of the top of the rotating disk 315. Multiple sliding grooves 317 are opened on the outer ring of the top of the rotating disk 315. The circular groove 316 is connected to the sliding groove 317. An arc-shaped block 318 is fixedly installed between each pair of sliding grooves 317. The bottom end of the fourth rotating shaft 34 is rotatably engaged with the top center of the base plate 1. A fixing block 319 is fixedly installed at the bottom end of the second rotating shaft 37. A fan-shaped plate 320 is fixedly installed on one side of the fixing block 319. One side of the fan-shaped plate 320 is slidably engaged with the inner wall of one of the arc-shaped blocks 318. A rotating bar 321 is fixedly installed on the other side of the fixing block 319. A rotating block 322 is fixedly installed at the bottom of the rotating bar 321. The rotating block 322 is slidably engaged with the sliding groove 317.

[0045] By adopting the above technical solution, when the second rotating shaft 37 rotates, it drives the fixed block 319 and the rotating block 322 to rotate. When the rotating block 322 enters one of the slide grooves 317 until it leaves the slide groove 317, it drives the rotating disk 315 to rotate, which in turn drives the fourth rotating shaft 34 and the placement disk 35 to rotate. When the rotating block 322 enters the circular groove 316 and rotates inside the circular groove 316, the fan-shaped plate 320 slides against the inner wall of the arc-shaped block 318, which plays a limiting role on the rotating disk 315. During this process, the rotating disk 315 and the placement disk 35 do not rotate, so that the polishing brush 27 can fully polish the side of the shell. In this way, the shell is rotated intermittently, which further improves the polishing effect.

[0046] The dust removal mechanism 5 includes a dust removal box 51. A piston plate 52 is slidably arranged inside the dust removal box 51. Straight rods 53 are symmetrically fixed at both ends on one side of the piston plate 52. A first connecting plate 54 is fixedly arranged through the straight rods 53 and at the bottom of the dust removal box 51. A second connecting plate 55 is fixedly arranged at the bottom of the first connecting plate 54. A dust outlet pipe 56 is connected to the top of the dust removal box 51. A first one-way valve 57 is installed on the surface of the dust outlet pipe 56. Support rods 58 are fixedly arranged at the bottom corners of the dust removal box 51. Dust guide pipes 59 are symmetrically connected at both ends on one side of the dust removal box 51. A second one-way valve 510 is installed on the surface of the dust guide pipe 59. A first suction pipe 511 is symmetrically connected to the top and bottom of the dust guide pipe 59. A second suction pipe 512 is connected to one side of the first suction pipe 511.

[0047] By adopting the above technical solution, when the shell is polished, the transmission mechanism 4 drives the second connecting plate 55 and the first connecting plate 54 to move back and forth, which in turn drives the piston plate 52 to move back and forth. When the piston plate 52 moves away from the shell, it generates suction near the second suction pipe 512. The air mixed with dust enters the second suction pipe 512, and enters the dust collection box 51 through the first suction pipe 511 and the dust guide pipe 59. The second one-way valve 510 only allows air to enter the dust collection box 51. When the piston plate 52 moves closer to the shell, the dust outlet pipe 56 is connected to other gas treatment equipment (existing technology, not described in detail). The air mixed with dust is discharged through the dust outlet pipe 56 and the first one-way valve 57, thus realizing the treatment of dust generated during the polishing process.

[0048] The transmission mechanism 4 includes a U-shaped frame 41 and an annular bar 42. The top of the U-shaped frame 41 has a mounting hole, and a connecting shaft 43 is rotatably mounted in the mounting hole. Two second pulleys 44 are mounted on one side of the connecting shaft 43. The two second pulleys 44 are driven and engaged by a second conveyor belt 48. One second pulley 44 is mounted on the connecting shaft 43, and the other second pulley 44 is mounted on the sleeve 33. A circular plate 45 is fixedly mounted on the top of the connecting shaft 43, and a mounting block 46 is fixedly mounted on the top of the circular plate 45. The outer wall of the mounting block 46 is slidably engaged with the inner wall of the annular bar 42. A third connecting plate 47 is fixedly mounted on one side of the annular bar 42. One end of the third connecting plate 47 is fixedly engaged with one side of the second connecting plate 55. The support rod 58 and the U-shaped frame 41 are both fixedly engaged with the other end of the top of the base plate 1.

[0049] By adopting the above technical solution, when the sleeve 33 rotates, it drives the second pulley 44 and the connecting shaft 43 to rotate, which in turn drives the connecting shaft 43 and the circular plate 45 to rotate, which in turn drives the mounting block 46 to rotate while sliding inside the annular bar 42. This causes the annular bar 42 and the third connecting plate 47 to move repeatedly in the horizontal direction, thereby driving the dust removal mechanism 5 to work normally.

[0050] The limiting mechanism 6 includes a top plate 61, an electric hydraulic cylinder 62 is installed at the bottom center of the top plate 61, an intermediate block 63 is fixedly installed at the output end of the electric hydraulic cylinder 62, a limiting plate 64 is rotatably installed at the bottom of the intermediate block 63, and vertical rods 65 are fixedly installed at the bottom corners of the top plate 61, with the bottom end of the vertical rod 65 fixedly engaged with the top outer ring of the bottom plate 1.

[0051] By adopting the above technical solution, when the housing of the reciprocating pump is placed on the placement plate 35, the electric hydraulic cylinder 62 is activated to extend it, which drives the limiting plate 64 to move down and contact the housing, thus limiting it. When the housing rotates, the limiting plate 64 rotates along the axial direction of the intermediate block 63.

[0052] Working principle:

[0053] When the housing of the reciprocating pump needs to be polished, the housing is placed on the placement plate 35, the electric hydraulic cylinder 62 is activated to extend it, which drives the limiting plate 64 to move down and contact the housing, thus limiting it. The polishing motor 23 is activated to drive the first rotating shaft 24, the outer rod 25 and the inner rod 26 to rotate, which in turn drives the polishing brush 27 to rotate. At the same time, the round block 28 rotates inside the mounting ring 22. The electric push rod 210 is activated to extend it, which drives the inner rod 26 to slide along the inner wall of the outer rod 25 and approach the housing to polish the housing.

[0054] When the first rotating shaft 24 rotates, it drives the bevel gear 310 to rotate, which in turn drives the third rotating shaft 32 and the first pulley 38 to rotate, which in turn drives the first spur gear 311 and the second rotating shaft 37 to rotate. When the second rotating shaft 37 rotates, it drives the fixed block 319 and the rotating block 322 to rotate. When the rotating block 322 enters one of the slide grooves 317 and leaves the slide groove 317, it drives the rotating disk 315 to rotate, which in turn drives the fourth rotating shaft 34 and the placement disk 35 to rotate. When the rotating block 322 enters the circular groove 316 and rotates inside the circular groove 316, the sector plate 320 slides against the inner wall of the arc block 318, which plays a limiting role on the rotating disk 315. During this process, the rotating disk 315 and the placement disk 35 do not rotate, so that the polishing brush 27 can fully polish the side of the shell. This achieves intermittent rotation of the shell and further improves the polishing effect.

[0055] When the second spur gear 312 and sleeve 33 rotate, they drive the second pulley 44 and connecting shaft 43 to rotate, which in turn drives the connecting shaft 43 and circular plate 45 to rotate, which in turn drives the mounting block 46 to rotate while sliding inside the annular bar 42. This causes the annular bar 42 and the third connecting plate 47 to move repeatedly in the horizontal direction, driving the second connecting plate 55 and the first connecting plate 54 to move back and forth, which in turn drives the piston plate 52 to move back and forth. When the piston plate 52 moves away from the outer shell, it generates suction near the second suction pipe 512. Air mixed with dust enters the second suction pipe 512, and enters the dust collection box 51 through the first suction pipe 511 and the dust guide pipe 59. The second one-way valve 510 only allows air to enter the dust collection box 51. When the piston plate 52 moves closer to the outer shell, the dust outlet pipe 56 is connected to other gas treatment equipment (existing technology, not described in detail). The air mixed with dust is discharged through the dust outlet pipe 56 and the first one-way valve 57, thus realizing the treatment of dust generated during the grinding process.
