Description

Technical Field

[0001] This application belongs to the field of plunger pump technology, and particularly relates to an expansion pipeline for a plunger pump. Background Technology

[0002] A piston pump is an important component of a hydraulic system. It relies on the reciprocating motion of a piston in a cylinder to change the volume of the sealed working chamber, thereby achieving oil suction and pressure.

[0003] Currently, existing plunger pumps cannot adjust the dimensions of the piston, inlet pipe, and reservoir during use. When it is necessary to increase the oil suction efficiency, it is necessary to control the operating speed of the pump. However, when the operating speed of the plunger pump is increased, the piston impact noise is louder, the oil outlet pipe vibrates more, and cracks in the pipe and buffer tank often occur.

[0004] To address this issue, we propose an expansion pipeline for a plunger pump. Utility Model Content

[0005] The purpose of this application is to solve the problem in the prior art that the storage size of the piston, inlet pipe and outlet pipe cannot be adjusted, and to propose an expansion pipeline for a plunger pump.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An expansion pipeline for a plunger pump includes a housing. A plunger is slidably connected inside the housing, and a piston is disposed on the outer side of the plunger. The inner wall of the piston and the inner wall of the plunger are threadedly connected to a first bolt. A disassembly block is snapped into the inside of the housing. Three sets of disassembly plates are snapped into the inside of the disassembly block and the inside of the housing. Two baffles are snapped into the inside of the housing. Two second bolts are threadedly connected to the inner wall of each baffle. The outer surface of each second bolt is threadedly connected to the inner wall of the housing. A sealing gasket is fixedly connected to the side of the two baffles that are far apart from each other. A circular ring plate is disposed on the side of the two sealing gaskets that are far apart from each other. The side of the two circular ring plates that are close to each other respectively contacts the side of the two sealing gaskets that are far apart from each other. A first storage rack is fixedly connected to the upper surface of the housing, and a second storage rack is fixedly connected to the front of the housing.

[0008] Preferably, the inner wall of the outer shell is rotatably connected to two short shafts, and a rotating block is fixedly connected to one end of each short shaft that is close to the other.

[0009] Preferably, the two rotating blocks are fixedly connected to a fixed shaft on their adjacent sides, a rotating plate is rotatably connected to the outer surface of the fixed shaft, a transmission block is rotatably connected to the inner wall of the rotating plate, and the front of the transmission block is fixedly connected to the end of the plunger near the transmission block.

[0010] Preferably, a stepper motor is fixedly connected to the right side of the housing, and the output end of the stepper motor is fixedly connected to the right end of one of the short shafts.

[0011] Preferably, the inner wall of the outer shell is fixedly connected to two fixed rubber pads, and the outer surface of each fixed rubber pad is fixedly connected to a folded rubber pad. The bottom surface of each folded rubber pad is in contact with the inner bottom wall of the outer shell, and the bottom surface of one of the folded rubber pads is in contact with the upper surface of one of the baffles.

[0012] Preferably, the inner wall of the outer shell is threaded with three sets of third bolts, each set having two third bolts, and the outer surface of each third bolt is threaded to the inner wall of the outer shell. The upper surface of the outer shell is fixedly connected to an output pipe, and the bottom surface of the outer shell is fixedly connected to an input pipe.

[0013] In summary, the technical effects and advantages of this application are as follows:

[0014] By removing the disassembly block and two disassembly plates that are snapped together inside the disassembly block, the circular space between the disassembly block and the outer shell increases due to the removal of the two disassembly plates. This allows for the storage of more air, which in turn increases the oil output flow rate when the plunger moves back and forth. The piston and first bolt are then installed, and the piston can be removed from the plunger using the threaded connection between the first bolt and the piston. Spare pistons of different diameters stored in the second storage rack can then be removed and fixed back to the plunger using the first bolt. This allows the piston diameter to be changed to match the size of the disassembly plate and the internal space of the outer shell, ensuring good sealing of the space before and after the piston. The baffle can be removed using the second bolt, and the annular plate can be replaced. Spare annular rings with larger opening diameters stored in the first storage rack can be taken out, allowing the inlet and outlet diameters of the pipes to be changed. This effectively avoids the problems of excessive piston impact noise and frequent pipe and buffer tank cracks that occur when the plunger pump needs to deliver oil efficiently due to the inability to adjust the piston, input pipe, and output pipe diameters.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 An expansion pipeline for a plunger pump includes a housing 1, with a plunger 21 slidably connected inside the housing 1. Two short shafts 2 are rotatably connected to the inner wall of the housing 1. A rotating block 10 is fixedly connected to one end of each short shaft 2 that is close to each other. By providing the short shafts 2 and the rotating blocks 10, a supporting force can be provided to the rotating blocks 10, and the rotating blocks 10 can be rotated.

[0022] A piston 22 is provided on the outer side of the plunger 21. The inner wall of the piston 22 and the inner wall of the plunger 21 are connected by a first bolt 20. A disassembly block 6 is snapped into the inside of the outer casing 1. A fixed shaft 17 is fixedly connected to one side of the two rotating blocks 10 that are close to each other. A rotating plate 18 is rotatably connected to the outer surface of the fixed shaft 17. A transmission block 19 is rotatably connected to the inner wall of the rotating plate 18. The front of the transmission block 19 is fixedly connected to the end of the plunger 21 near the transmission block 19. With the fixed shaft 17, rotating plate 18 and transmission block 19 provided, when the rotating block 10 rotates, it will drive the fixed shaft 17 to rotate around the center of the rotating block 10. When the fixed shaft 17 rotates, the rotating plate 18 will also rotate with the rotating block 10. However, one end of the rotating plate 18 is connected to the transmission block 19, so it will drive the transmission block 19 and the plunger 21 to move in a cycle.

[0023] The disassembly block 6 and the outer casing 1 are fitted with three sets of disassembly plates 11. The inner casing 1 is fitted with two baffles 14, each baffle 14 having two second bolts 23 threaded onto its inner wall. The outer surface of each second bolt 23 is threaded onto the inner wall of the outer casing 1. A stepper motor 3 is fixedly connected to the right side of the outer casing 1, and the output end of the stepper motor 3 is fixedly connected to the right end of one of the short shafts 2. The stepper motor 3 provides power for the operation of the equipment.

[0024] Sealing gaskets 16 are fixedly connected to the opposite sides of the two baffles 14. Circular ring plates 15 are provided on the opposite sides of the two sealing gaskets 16. The opposite sides of the two circular ring plates 15 contact the opposite sides of the two sealing gaskets 16. A first storage rack 4 is fixedly connected to the upper surface of the outer casing 1. Two fixing rubber pads 13 are fixedly connected to the inner wall of the outer casing 1. A folded rubber pad 12 is fixedly connected to the outer surface of each fixing rubber pad 13. The bottom surface of each folded rubber pad 12 contacts the inner bottom wall of the outer casing 1. The bottom surface of one of the folded rubber pads 12 contacts the upper surface of one of the baffles 14. By providing a fixed rubber pad 13 and a folding rubber pad 12, the folding rubber pad 12 can fold using its own soft properties. For example, when the piston 22 moves forward, it will compress the gas in the space in front of the piston 22, increasing the gas pressure in the space in front of the piston 22. This will push the upper folding rubber pad 12 to fold upward, allowing the oil in the space in front of the piston 22 to flow upward through the upper folding rubber pad 12. Conversely, when the piston 22 moves backward, the pressure in the space in front of the piston 22 decreases, which will pull the lower folding rubber pad 12 to fold, allowing the oil to enter the space in front of the piston 22.

[0025] The front of the outer casing 1 is fixedly connected to a second storage rack 9. The inner wall of the outer casing 1 is threaded with three sets of third bolts 7, each set containing two bolts. The outer surface of each third bolt 7 is threaded to the inner wall of the outer casing 1. The upper surface of the outer casing 1 is fixedly connected to an output pipe 5, and the bottom surface of the outer casing 1 is fixedly connected to an input pipe 8. The outer casing 1 can be fixed by the third bolts 7. The output pipe 5 can output oil, and the input pipe 8 can input oil into the space in front of the piston 22.

[0026] The working principle of this utility model is as follows: When using the equipment, the stepper motor 3 can be controlled to run. The operation of the stepper motor 3 will drive the short shaft 2, rotating block 10, rotating plate 18 and fixed shaft 17 to rotate. When the rotating plate 18 rotates with the fixed shaft 17, it will also pull the plunger 21 and transmission block 19 to move in a cyclic reciprocating motion, thereby completing the purpose of conveying oil. This technology is a conventional technology. If it is necessary to accelerate the oil conveying rate, the running speed of the stepper motor 3 can be increased. This will increase the reciprocating efficiency of the plunger 21 and piston 22, which will cause the piston 22 to make a louder noise during operation. At this time, the disassembly block 6 can be disassembled, and then two disassembly plates 11 that are stuck inside the disassembly block 6 can be removed. At this time, since two disassembly plates 11 are removed, the circular space between the disassembly block 6 and the outer shell 1 will increase, so more air can be stored. This will further increase the amount of oil output when the plunger 21 moves back and forth once. Then, by setting the piston... Using the threaded connection between the first bolt 20 and the piston 22, the piston 22 can be removed from the plunger 21. Then, spare pistons of different diameters stored in the second storage rack 9 can be removed and fixed to the plunger 21 again using the first bolt 20. This allows the diameter of the piston 22 to be matched with the size of the disassembly plate 11 and the internal space of the outer casing 1, thus ensuring good sealing of the space before and after the piston 22. The baffle 14 can be removed using the second bolt 23, and the annular plate 15 can be replaced to take out the spare annular ring with a larger opening diameter stored in the first storage rack 4. This allows the diameter of the pipe inlet and outlet to be changed. This effectively avoids the problem of excessive impact noise from the piston 22 inside the plunger 21 pump and frequent cracks in the pipes and buffer tank when the plunger 21 pump needs to deliver oil at high efficiency due to the non-adjustable diameter of the piston 22, input pipe 8 and output pipe 5.
