Description

Technical Field

[0001] The utility model relates to the technical field of plunger pumps, in particular to a plunger pump which is easy to connect. Background Art

[0002] Petroleum engineering includes oil reservoirs, drilling, oil production and oil surface engineering. In the process of oil extraction, acid fracturing technology is usually used to improve oil and gas seepage conditions, thereby increasing oil production. In the acid fracturing operation, a plunger pump is used. The plunger pump can be used to inject acid into the formation, thereby crushing the rocks in the formation and forming cracks. The existing plunger pump still has certain defects when used.

[0003] In the prior art, the plunger pump is an important device of the hydraulic system. It relies on the reciprocating motion of the plunger in the cylinder to change the volume of the sealed working chamber to achieve liquid suction and discharge. At the same time, the plunger pump can transport various liquids. During the use of the plunger pump, the pipeline needs to be docked and installed on the feed port end and the discharge port end of the connecting pipe respectively, so as to transport the liquid through the pipeline. The traditional flange and bolt connection and fixing method is not only time-consuming and labor-intensive, but also requires the use of various tools during the disassembly and maintenance process, which makes it difficult to quickly dock and assemble the plunger pump and the pipeline. Utility Model Content

[0004] The utility model aims to provide a plunger pump which is easy to connect, so as to solve the problem that the connection between the plunger pump and the pipeline in the current market is inconvenient as mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a plunger pump that is easy to dock, comprising: a pump body, a connecting pipe, a feed port, a discharge port, a plunger push rod, a pipeline and a connecting block, the outer side of the pump body is connected with a connecting pipe, one end of the connecting pipe is provided with a feed port, and the other end of the connecting pipe is provided with a discharge port, the interior of the connecting pipe is connected with the plunger push rod, the ends of the feed port and the discharge port are both provided with pipelines, and the connecting block is respectively welded on both sides of the feed port and the discharge port, the interior of the connecting block is connected with a rotating rod through a bearing, the outer side of the rotating rod is welded with a first gear, the side of the connecting block close to the rotating rod is connected with a threaded column through a bearing, the outer side of the threaded column is welded with a second gear, the outer side of the threaded column is movably connected with a moving block, the outer side of the moving block is welded with a limiting block, the inner walls of the feed port and the discharge port are both equipped with sealing sleeves, the end of the pipeline is welded with a plug-in block, and the interior of the plug-in block is welded with a conical clamping block.

[0006] Preferably, a meshing structure is formed between the first gear and the second gear, and a sliding structure is formed between the moving block and the connecting block.

[0007] Preferably, a clamping structure is formed between the plug-in block and the limiting block through a conical clamping block.

[0008] Preferably, a connecting plate is installed at the bottom of the pump body, and a connecting seat is welded at the bottom of the connecting plate.

[0009] Preferably, a first knob is connected through one side of the connecting seat, and a second knob is connected through the other side of the connecting seat.

[0010] Preferably, a fixing rod is welded inside the connecting seat, and a supporting rod is movably connected to the outer side of the fixing rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the plunger pump which is easy to dock can drive the plug-in block to penetrate the ends of the feed port and the discharge port respectively when pushing the pipeline to move; when the ends of the pipeline are docked with the ends of the feed port and the discharge port respectively, the sealing sleeve can be plugged into the inside of the pipeline; when the first gear rotates, it can drive the second gear to engage and rotate; the first knob and the second knob can limit the position of the support rod so that the support height of the support rod can be fine-tuned, so that the pump body can be stably placed on the ground; through this simple and convenient method, the pump body can be stably placed, and the pump body is not easy to tip over during use.

[0012] 1. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment, but the docking and assembly between the connecting pipe on the plunger pump and the pipeline is relatively troublesome. When the pipeline is pushed to move, the plug-in block can be driven to penetrate the ends of the feed port and the discharge port respectively. When the ends of the pipeline are docked with the ends of the feed port and the discharge port respectively, the sealing sleeve can be plugged into the inside of the pipeline. When the first gear rotates, it can drive the second gear to engage and rotate. When the second gear rotates, it can drive the threaded column to rotate. When the moving block thread slides, it can drive the limit block to move. When the end of the limit block is plugged into the inside of the plug-in block, the limit block can be engaged and docked with the plug-in block through the conical clamping block. At this time, the limit block can limit and fix the pipeline. Through this simple and convenient method, the pipeline can be quickly docked with the ends of the feed port and the discharge port, thereby improving the docking and installation efficiency of the plunger pump.

[0013] 2. During use, the plunger pump is usually placed directly on the oil field land. Since it is difficult to have a flat place on the land surface, the plunger pump is prone to tipping over during use. For this reason, the first knob and the second knob can be rotated respectively so that the ends of the first knob and the second knob are moved away from the outside of the support rod. When the support rod moves, it can be rotated through the fixed rod. When the fixed rod is rotated to a specified angle, the first knob and the second knob can be rotated. The first knob and the second knob can limit the position of the support rod so that the supporting height of the support rod can be fine-tuned, so that the pump body can be stably placed on the ground. Through this simple and convenient method, the pump body can be stably placed, making it less likely for the pump body to tip over during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In specific implementation, the plunger pump has the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment, but the docking and assembly between the connecting pipe 2 and the pipeline 6 on the plunger pump is more troublesome. For this reason, the two sets of pipelines 6 can be pushed to the ends of the feed port 3 and the discharge port 4 respectively. When the pipeline 6 is pushed to move, the plug-in block 15 can be driven to penetrate the ends of the feed port 3 and the discharge port 4 respectively. When the ends of the pipeline 6 are docked with the ends of the feed port 3 and the discharge port 4 respectively, the sealing sleeve 14 can be plugged into the inside of the pipeline 6. At this time, the rotating rod 8 can be rotated, and the rotating rod 8 rotates When the first gear 9 moves, it can drive the first gear 9 to rotate, and when the first gear 9 rotates, it can drive the second gear 11 to mesh and rotate, and when the second gear 11 rotates, it can drive the threaded column 10 to rotate, and when the threaded column 10 rotates, it can drive the moving block 12 to slide threadedly, and when the moving block 12 slides threadedly, it can drive the limit block 13 to move.

At this time, the limit block 13 can limit and fix the pipe 6.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 It can be seen that, through this simple and convenient method, the pipeline 6 can be quickly docked with the ends of the feed port 3 and the discharge port 4, thereby improving the docking and installation efficiency of the plunger pump.

[0024] See also Figure 1 and Figure 4It can be seen that a connecting plate 17 is installed at the bottom of the pump body 1, a connecting seat 18 is welded to the bottom of the connecting plate 17, a first knob 19 is penetrated and connected to one side of the connecting seat 18, and a second knob 20 is penetrated and connected to the other side of the connecting seat 18, a fixing rod 21 is welded inside the connecting seat 18, a support rod 22 is movably connected to the outer side of the fixing rod 21, and a rotating structure is formed between the support rod 22 and the fixing rod 21.

[0025] During specific implementation, the plunger pump is usually placed directly on the oil field land during use. Since it is difficult to have a flat place on the land surface, the plunger pump is prone to tipping over during use. For this reason, the first knob 19 and the second knob 20 can be rotated respectively so that the ends of the first knob 19 and the second knob 20 are moved away from the outside of the support rod 22. At this time, the support rod 22 can be pushed. When the support rod 22 moves, it can be rotated through the fixed rod 21. When the fixed rod 21 is rotated to a specified angle, the first knob 19 and the second knob 20 can be rotated so that the ends of the first knob 19 and the second knob 20 are close to both sides of the support rod 22. The first knob 19 and the second knob 20 can limit the position of the support rod 22, so that the support height of the support rod 22 can be fine-tuned, so that the pump body 1 can be stably placed on the ground.

[0026] See also Figure 1 and Figure 4 It can be seen that, through this simple and convenient method, the pump body 1 can be placed stably, so that the pump body 1 is not easy to tip over during use.

[0027] In summary, when the plunger pump that is easy to dock is used, when the plunger push rod 5 moves in a direction away from the feed port 3 and the discharge port 4, a negative pressure is formed inside the connecting tube 2. At this time, the feed port 3 is opened, and the liquid is sucked into the connecting tube 2. When the plunger push rod 5 moves in a direction close to the feed port 3 and the discharge port 4, a positive pressure is formed inside the connecting tube 2. At this time, the feed port 3 is closed and the discharge port 4 is opened, thereby transporting the liquid inside the connecting tube 2 out. The plunger pump is a prior art and will not be described in detail here. When the end of the limit block 13 is plugged into the plug-in block 15, the limit block 13 can be engaged and docked with the plug-in block 15 through the conical clamping block 16 At this time, the limit block 13 can limit and fix the pipe 6. Through this simple and convenient method, the pipe 6 can be quickly connected with the ends of the feed port 3 and the discharge port 4, thereby improving the docking and installation efficiency of the plunger pump. The first knob 19 and the second knob 20 can limit the position of the support rod 22, so that the supporting height of the support rod 22 can be fine-tuned, so that the pump body 1 can be stably placed on the ground. Through this simple and convenient method, the pump body 1 can be placed stably, making it difficult for the pump body 1 to tip over during use.
