Description

Technical Field

[0001] The utility model belongs to the technical field of high-pressure plunger pumps, and in particular relates to a high-pressure plunger pump with a self-adaptive pre-pressure regulating function. Background Art

[0002] High-pressure plunger pump is a hydraulic component that can produce high-pressure fluid. Its main function is to convert mechanical energy into hydraulic energy, thereby achieving pressure and flow control of the hydraulic system. Its operating pressure can generally reach 10MPa-100MPa, or even higher, which enables it to meet the needs of a variety of high-pressure applications.

[0003] Secondly, high-pressure plunger pumps play an important role in industrial applications. For example, in the fields of petroleum industry, chemical industry, fertilizer, metallurgy, steel mills, etc., high-pressure plunger pumps are often used for tasks such as high-pressure water scaling, high-pressure water cleaning and scaling. In addition, it can also be used to provide a power source for oil field injection water, or play a role in boiler water and hydraulic presses. In the manufacturing industries such as food and medicine, high-pressure plunger pumps are also often used to manufacture high-pressure river water components.

[0004] When utilizing water resources such as rivers, high-pressure plunger pumps are key equipment responsible for sucking in and treating the river water. However, the river water inevitably contains impurities such as solid sediments, suspended matter and organic matter. These impurities will be sucked into the water inlet of the high-pressure plunger pump during the flow of the river water. If there is a lack of effective filtering measures at the water inlet, these impurities will easily accumulate inside the pump and form blockages. This will not only directly affect the normal operation of the high-pressure plunger pump, but also lead to a significant reduction in its working efficiency, thereby affecting the smoothness and efficiency of the entire water resource utilization process.

However, the river water inevitably contains impurities such as solid sediments, suspended matter and organic matter. These impurities will be sucked into the water inlet end of the high-pressure plunger pump during the flow of river water. If there is a lack of effective filtering measures at the water inlet end, these impurities will easily accumulate inside the pump and form a blockage. This will not only directly affect the normal operation of the high-pressure plunger pump, but will also lead to a significant reduction in its working efficiency, thereby affecting the smoothness and efficiency of the entire water resource utilization process.

[0014] As a preferred embodiment of the present invention, a first cavity is provided in the base;

[0022] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0023] When the high-pressure plunger pump needs to draw water from the river, it uses its powerful suction to successfully pump the river water from the river. In this process, the river water first enters the high-pressure plunger pump through the water inlet, but if the river water contains impurities, these impurities may interfere with the normal operation of the pump.

[0024] To solve this problem, the high-pressure plunger pump is equipped with an efficient filtering mechanism. When the first fixed shaft starts to rotate, it drives the filter element to rotate in the annular groove. This rotation not only effectively blocks the impurities on one side of the filter element, the impurities will be filtered out of the river water by the filter element, so that the river water and the impurities can be separated, but also the power generated by the rotation can prevent the impurities from settling at the bottom, thus avoiding clogging.

[0025] Specifically, when river water flows in through the water inlet, the filter element starts to rotate under the drive of the rotating shaft. Its rotation is like a filter, blocking impurities outside and allowing only clean river water to pass through and then smoothly enter the high-pressure plunger pump. At the same time, the rotating filter element also plays a stirring role, stirring up the impurities deposited at the bottom and preventing them from settling again, thereby ensuring the long-term filtering effect and stable operation of the pump.

DETAILED DESCRIPTION

[0031] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0032] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0033] See also Figures 1 to 4 The utility model provides a high-pressure plunger pump with an adaptive pre-pressure adjustment function, comprising a base 1, on which a high-pressure plunger pump 11 is arranged, characterized in that: a first water inlet pipe 12 is arranged at the water inlet end of the high-pressure plunger pump 11, an annular groove 13 is provided in the first water inlet pipe 12, and a filter is installed in the annular groove 13;

[0034] The filter element includes a filter screen 14, and the filter screen 14 is arranged in the annular groove 13;

[0035] A first fixed shaft 15 is fixedly connected to the center of the filter screen 14 .

[0036] Adopt the above scheme: when in use, when the high-pressure plunger pump 11 needs to absorb water from the river channel, it uses its own suction force to pump the river water up from the river channel. In this process, the river water will flow into the high-pressure plunger pump 11 through the water inlet end. If the river water contains impurities, the first fixed shaft 15 rotates at this time, and it will drive the filter element to rotate synchronously in the annular groove 13. This rotation action effectively blocks the impurities on one side of the filter element, thereby realizing the separation of impurities and river water. After such separation, the river water enters the high-pressure plunger pump 11 through the water inlet end.

[0037] At the same time, during the rotation of the filter element, the impurities deposited at the bottom are stirred up by the rotation speed to prevent them from being deposited at the bottom for a long time and causing blockage. This not only improves the efficiency of the high-pressure plunger pump 11 in extracting river water, but also ensures the continuous and effective operation of the filter element.

[0038] Specifically, when the river water flows into the water inlet, the first fixed shaft 15 starts to drive the filter screen 14 to rotate in the annular groove 13. The rotating filter screen 14 can effectively block the impurities on one side, so that the river water and the impurities can be separated. Then the river water enters the high-pressure plunger pump 11 through the water inlet. In this process, the filter screen 14 uses the gaps between its meshes to stir the river water to stir up the impurities deposited at the bottom, preventing them from staying at the bottom for a long time. This ensures the efficient operation and filtering effect of the high-pressure plunger pump 11 during the water absorption process.

[0039] See also Figure 1 , Figure 2 and Figure 4 , a second water inlet pipe 2 is fixedly connected to one side of the first water inlet pipe 12;

[0040] The first fixed shaft 15 extends into the second water inlet pipe 2;

[0041] The outer surface of the first fixed shaft 15 is fixedly connected with a spiral blade 21;

[0042] The spiral blade 21 is located on one side of the filter screen 14 .

[0043] Adopting the above scheme: when in use, when the high-pressure plunger pump 11 needs to pump water from the river, its first fixed shaft 15 will drive the spiral blade 21 to rotate. The spiral blade 21 not only helps the high-pressure plunger pump 11 to transport river water, but also plays a key role: if the river water contains large impurities, the spiral blade 21 will break these impurities so that they can smoothly enter the first water inlet pipe 12. The river water broken by the spiral blade 21, including the small impurities therein, will flow into the first water inlet pipe 12 through the second water inlet pipe 2, and then the broken impurities can be further filtered by the filter element. In this way, the spiral blade 21 not only plays the role of transporting river water, but also ensures the quality of the extracted river water and avoids clogging of the water inlet pipe.

[0044] See also Figure 4 A first one-way valve 3 is installed in the first water inlet pipe 12, and the first one-way valve 3 is located on one side of the filter screen 14. A second one-way valve 31 is installed in the second water inlet pipe 2, and the second one-way valve 31 is located on one side of the first fixed shaft 15.

[0045] With the above solution, when the filter element has completed the task of filtering impurities and is ready to discharge, the one-way valves in the first water inlet pipe 12 and the second water inlet pipe 2 are both in a closed state. At this time, the first one-way valve 3 in the first water inlet pipe 12 is closed, which can effectively prevent the river water from continuing to flow into the high-pressure plunger pump 11.

[0046] At the same time, the second one-way valve 31 in the second water inlet pipe 2 is closed, which can also ensure that the river water does not enter the second water inlet pipe 2. When both one-way valves are closed, part of the river water will temporarily remain in the first water inlet pipe 12 and the second water inlet pipe 2, which can facilitate the subsequent discharge of accumulated impurities.

[0047] See also Figure 2 and Figure 4 , a first cavity 4 is defined in the base 1;

[0048] A plurality of delivery pipes 41 are provided between the second water inlet pipe 2 and the base 1;

[0049] One end of the delivery pipeline 41 is connected to the first water inlet pipe 12;

[0050] The other end of the delivery pipe 41 is communicated with the first cavity 4;

[0051] A third one-way valve 42 is installed in each of the delivery pipelines 41 .

[0052] The above scheme is adopted: when in use, when the first water inlet pipe 12 and the second water inlet pipe 2 need to discharge impurities, the one-way valve is closed and the river water is temporarily stored. At this time, the third one-way valve 42 is opened, and the first fixed shaft 15 drives the spiral blade 21 to rotate in the opposite direction, moving the river water, and driving the impurities into the first cavity 4 through the conveying pipe 41. If the impurities are not completely discharged, the spiral blade 21 rotates forward, and the river water and impurities are circulated again until the impurities are completely discharged.

[0053] The forward and reverse rotation of the spiral blade 21 realizes the reciprocating cycle discharge of impurities in the water inlet pipe, ensuring the thorough removal of impurities. This process does not require manual intervention, is easy to operate and efficient, greatly improves the cleaning efficiency and stability of the equipment, and extends the service life of the equipment.

[0054] See also Figure 3 A worm gear 5 is fixedly connected to the outer surface of the first fixed shaft 15. The worm gear 5 is located on one side of the spiral blade 21. A worm 51 is meshed on the lower side of the worm gear 5. A motor 52 is provided at one end of the worm 51. The output end of the motor 52 is fixedly connected to the worm 51.

[0055] The above scheme is adopted: when in use, when the output end of the motor 52 is started, it drives the worm 51 to rotate, and the worm 51 is tightly meshed with the worm wheel 5, so that the worm wheel 5 rotates synchronously with the worm 51. The rotation of the worm wheel 5 then drives the first fixed shaft 15 to rotate, realizing the required power transmission. This transmission method is not only compact in structure, but also has a large transmission ratio, and can effectively transmit a large torque while ensuring stability. In addition, since the worm wheel 5 and the worm 51 transmission are self-locking, they can maintain a certain position stability even under the action of external force.

[0056] See also Figure 1 and Figure 3 A support frame 6 is installed at one end of the first fixed shaft 15, one side of the support frame 6 is fixedly connected to the inner wall of the first water inlet pipe 12, and a water groove 61 is opened in the support frame 6.

[0057] In the above scheme, when the river water flows into the first water inlet pipe 12, the river water first contacts the support frame 6. The support frame 6 is designed with a water channel 61, which allows the river water to smoothly flow through the water channel 61 while contacting the support frame 6. It is ensured that the support frame 6 does not become an obstacle to the flow of the river water, thereby maintaining the natural flow rate of the river water in the pipeline.

[0058] The working principle of this utility model:

[0059] When the high-pressure plunger pump 11 needs to draw water from the river channel, it uses its own suction force to draw the river water from the river channel. In this process, the river water will first flow through the water inlet end and then enter the interior of the high-pressure plunger pump 11. However, if the river water contains impurities, the first fixed shaft 15 starts to rotate, and it will drive a filter element to rotate synchronously in the annular groove 13. This rotation action has a dual effect: on the one hand, it can effectively block the impurities on one side of the filter element, allowing the river water to pass through clearly, realizing the effective separation of impurities and river water; on the other hand, during the rotation of the filter element, the force generated by its rotation speed can stir up the impurities deposited at the bottom, thereby avoiding the blockage problem caused by the long-term deposition of impurities.

[0060] Specifically, the filter screen 14 is used as the filter element, and its role cannot be ignored. When river water flows into the water inlet, the first fixed shaft 15 drives the filter screen 14 to continuously rotate in the annular groove 13. In this way, the rotating filter screen 14 can act as a barrier to block impurities on one side, ensuring that only clear river water can enter the interior of the high-pressure plunger pump 11 through the water inlet.

[0061] At the same time, during the rotation of the filter screen 14, the gaps between the meshes can not only filter out impurities, but also effectively stir up the impurities deposited at the bottom by stirring the river water. In this way, the impurities can be prevented from staying at the bottom for a long time, thereby ensuring the water absorption efficiency and filtering effect of the high-pressure plunger pump 11.
