Description

Technical Field

[0001] This utility model relates to the field of plunger pump technology, specifically a plunger pump with a corrosion-resistant plunger pump rod. Background Technology

[0002] A piston pump is a positive displacement hydraulic pump that achieves oil suction and pressure through the reciprocating motion of a piston within a cylinder. Piston pumps are characterized by their ability to operate under high pressure, compact structure, high efficiency, and convenient flow regulation. They are widely used in applications requiring high pressure, large flow rates, and flow regulation, such as hydraulic presses, construction machinery, and ships. As a commonly used hydraulic pump, piston pumps need to resist corrosive media. To improve their durability and reliability in these environments, manufacturers use special materials and coatings to manufacture key components, especially the piston rod.

[0003] As disclosed in Chinese Patent CN214836909U, a plunger pump with a corrosion-resistant plunger pump rod is designed with a threaded shaft, a plunger rod, and a positioning shaft. This design, combined with the galvanized layer on the outside of the plunger rod, the helical connection between the threaded shaft and the slider, and the sliding connection between the positioning shaft and the slider and the plunger pump, improves the corrosion resistance of the plunger rod during use, ensuring the sealing effect inside the plunger pump. At the same time, it facilitates the disassembly and assembly of the plunger pump when the device is damaged and needs repair, making the operation simple, convenient, and quick.

[0004] Although the plunger pump is galvanized for corrosion protection, the entire plunger pump is still exposed to the outside environment for a long time, and it will eventually corrode and be damaged. Therefore, we propose a plunger pump with a corrosion-resistant plunger pump rod that can provide overall protection to the plunger pump and improve its corrosion resistance. Utility Model Content

[0005] The purpose of this invention is to provide a plunger pump with a corrosion-resistant plunger pump rod to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a plunger pump with a corrosion-resistant plunger pump rod, comprising a pump rod, a pump body slidably disposed on the outer wall of the pump rod, an mounting plate fixedly installed on the outer wall of the pump body, and a processing component disposed outside the pump body, the processing component including a protective component disposed outside the pump body, and a cleaning component disposed on the side of the protective component near the mounting plate.

[0007] Preferably, the protective assembly includes a fixed plate fixedly installed on the outer wall of the pump rod, a first connecting plate fixedly installed at the bottom of the fixed plate, a protective tube fixedly installed at the bottom of the first connecting plate, a second connecting plate fixedly installed at the bottom of the protective tube, a movable plate fixedly installed at the bottom of the second connecting plate, a sliding groove opened inside the protective tube, a slider slidably arranged inside the sliding groove, a first rubber ring fixedly installed at the bottom of the fixed plate, a second rubber ring fixedly installed on the top surface of the first connecting plate, a third rubber ring fixedly installed at the bottom of the second connecting plate, and a fourth rubber ring fixedly installed on the top surface of the movable plate.

[0008] Preferably, the cleaning assembly includes a cleaning layer fixedly installed on the side of the movable disc away from the second connecting disc, a wear-resistant layer fixedly installed on the outer wall of the cleaning layer, a sealing layer fixedly installed on the outer wall of the wear-resistant layer, an anti-corrosion layer fixedly installed on the outer wall of the sealing layer, and a ceramic layer fixedly installed on the outer wall of the anti-corrosion layer.

[0009] Preferably, the slider is fixedly installed on the outer wall of the pump body, and the slider is slidably configured with a groove opened on the inner wall of the protective pipe. Under its constraint, the sliding of the protective pipe can be made more stable.

[0010] Preferably, the first, second, third, and fourth rubber rings are made of rubber. The first and second rubber rings are in contact with each other, and the third and fourth rubber rings are in contact with each other. Under this constraint, the sealing between the fixed plate, the first connecting plate, the protective tube, the second connecting plate, and the movable plate can be increased, and corrosive substances can be prevented from corroding the pump rod and the pump body.

[0011] Preferably, the cleaning layer is slidably disposed with respect to the outer wall of the pump body. The cleaning layer is made of a flexible material, which allows for cleaning of the outer wall of the pump body while preventing scratches.

[0012] Preferably, the ceramic layer is made of silicon nitride and the anti-corrosion layer is made of an anti-corrosion material, which can extend the service life of the cleaning component.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This plunger pump with an anti-corrosion plunger pump rod comprises a protective assembly. When protection of the pump rod and pump body is required, a fixed disc, a first connecting disc, a protective tube, a second connecting disc, and a movable disc are bolted together to the outer wall of the pump rod and pump body. When the pump rod slides outward, the fixed disc, fixedly mounted on the outer wall of the pump rod, moves the first connecting disc via the bolt assembly. The first connecting disc, through the protective tube, moves the second connecting disc, which in turn moves the movable disc against the outer wall of the pump body. Under the protection of the protective tube, the outer wall of the pump rod remains sealed to prevent corrosion. Because the movable disc slides against the outer wall of the pump body via a cleaning assembly, when the pump rod slides outward... When the pump body slides inside, the cleaning components clean the outer wall of the pump body, and the protective tube resets to cover the pump body. With the cooperation of the fixed plate, the first connecting plate, the protective tube, the second connecting plate, and the movable plate, the pump rod and the pump body are protected as a whole, preventing the plunger pump from being damaged by corrosion. With the contact and cooperation of the first rubber ring, the second rubber ring, the third rubber ring, and the fourth rubber ring, the connection between the fixed plate, the first connecting plate, the protective tube, the second connecting plate, and the movable plate can be more sealed, further protecting the pump rod and the pump body and extending the overall service life of the plunger pump. With the sliding limit of the slider fixed on the outer wall of the pump body and the sliding groove opened on the inner wall of the protective tube, the protective tube slides more stably outside the pump rod and the pump body.

[0015] 2. This plunger pump with an anti-corrosion plunger pump rod is composed of a cleaning assembly as one component. When protection of the plunger pump is required, the entire cleaning assembly is protected by a ceramic layer. The ceramic layer can improve the overall rigidity of the cleaning assembly. Under the constraint of the anti-corrosion layer, the anti-corrosion effect can be improved. Under the constraint of the sealing layer, the sealing performance between the cleaning assembly and the outer wall of the pump body can be improved. Under the constraint of the wear-resistant layer, the cleaning assembly can be made more wear-resistant and have a longer service life. Under the constraint of the cleaning layer, the outer wall of the pump body exposed to the outside can be cleaned, thus extending the overall service life of the plunger pump.

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] Example 1

[0025] A preferred embodiment of the plunger pump with a corrosion-resistant plunger pump rod provided by this utility model is, for example... Figures 1 to 6 As shown: A plunger pump with a corrosion-resistant plunger pump rod, including a pump rod 1;

[0026] A pump body 2 is slidably mounted on the outer wall of the pump rod 1;

[0027] A mounting plate 3 is fixedly installed on the outer wall of the pump body 2;

[0028] The pump body 2 is equipped with a processing component 4. The processing component 4 includes a protective component 41 installed outside the pump body 2. The protective component 41 includes a fixed plate 411 fixedly installed on the outer wall of the pump rod 1. A first connecting plate 412 is fixedly installed at the bottom of the fixed plate 411. A protective tube 413 is fixedly installed at the bottom of the first connecting plate 412. A second connecting plate 414 is fixedly installed at the bottom of the protective tube 413. A movable plate 415 is fixedly installed at the bottom of the second connecting plate 414. A sliding groove 416 is opened inside the protective tube 413. A slider 417 is slidably installed inside the sliding groove 416. A first rubber ring 418 is fixedly installed at the bottom of the fixed plate 411. A second rubber ring 419 is fixedly installed on the top surface of the first connecting plate 412. A third rubber ring 420 is fixedly installed at the bottom of the second connecting plate 414. A fourth rubber ring 421 is fixedly installed on the top surface of the movable plate 415.

[0029] In this embodiment, when protection of the pump rod 1 and pump body 2 is required, the fixed plate 411, the first connecting plate 412, the protective tube 413, the second connecting plate 414, and the movable plate 415 are installed on the outer wall of the pump rod 1 and pump body 2 by bolt assembly. When the pump rod 1 slides outward to the pump body 2, the fixed plate 411 fixedly installed on the outer wall of the pump rod 1 drives the first connecting plate 412 to move accordingly through the bolt assembly. The first connecting plate 412 drives the second connecting plate 414 to move accordingly through the protective tube 413. The second connecting plate 414 drives the movable plate 415 to slide on the outer wall of the pump body 2. Under the protection of the protective tube 413, the outer wall of the pump rod 1 is always in a sealed state to avoid corrosion of the outer wall of the pump body 2. Since the movable plate 415 slides against the outer wall of the pump body 2 through the cleaning assembly 43, when the pump rod 1 slides inward to the pump body 2, the cleaning assembly 43 cleans the pump body 2. The outer wall of pump body 2 is cleaned, and the protective tube 413 is reset to fit the pump body 2. With the cooperation of the fixed plate 411, the first connecting plate 412, the protective tube 413, the second connecting plate 414 and the movable plate 415, the pump rod 1 and the pump body 2 are protected as a whole, avoiding corrosion damage to the plunger pump. With the contact and cooperation of the first rubber ring 418, the second rubber ring 419, the third rubber ring 420 and the fourth rubber ring 421, the connection between the fixed plate 411, the first connecting plate 412, the protective tube 413, the second connecting plate 414 and the movable plate 415 can be more sealed, further protecting the pump rod 1 and the pump body 2, so as to extend the overall service life of the plunger pump. With the sliding limit of the slider 417 fixedly installed on the outer wall of the pump body 2 and the sliding groove 416 opened on the inner wall of the protective tube 413, the protective tube 413 slides more stably outside the pump rod 1 and the pump body 2.

[0030] Furthermore, the slider 417 is fixedly installed on the outer wall of the pump body 2, and the slider 417 is slidably set with the groove 416 opened on the inner wall of the protective tube 413. Under its restriction, the sliding of the protective tube 413 can be made more stable.

[0031] Furthermore, the first rubber ring 418, the second rubber ring 419, the third rubber ring 420, and the fourth rubber ring 421 are made of rubber. The first rubber ring 418 and the second rubber ring 419 are in contact with each other, and the third rubber ring 420 and the fourth rubber ring 421 are in contact with each other. Under this constraint, the sealing between the fixed plate 411, the first connecting plate 412, the protective tube 413, the second connecting plate 414, and the movable plate 415 can be increased, thus preventing corrosive substances from corroding the pump rod 1 and the pump body 2.

[0032] Example 2

[0033] Based on Example 1, a preferred embodiment of the plunger pump with a corrosion-resistant plunger pump rod provided by this utility model is, for example... Figures 1 to 6As shown: The cleaning component 43 includes a cleaning layer 431 fixedly installed on the side of the movable disc 415 away from the second connecting disc 414. A wear-resistant layer 432 is fixedly installed on the outer wall of the cleaning layer 431. A sealing layer 433 is fixedly installed on the outer wall of the wear-resistant layer 432. An anti-corrosion layer 434 is fixedly installed on the outer wall of the sealing layer 433. A ceramic layer 435 is fixedly installed on the outer wall of the anti-corrosion layer 434.

[0034] In this embodiment, when protection of the plunger pump is required, the cleaning component 43 is protected by the ceramic layer 435. The ceramic layer 435 can improve the overall rigidity of the cleaning component 43. Under the restriction of the anti-corrosion layer 434, the anti-corrosion effect can be improved. Under the restriction of the sealing layer 433, the sealing performance between the cleaning component 43 and the outer wall of the pump body 2 can be improved. Under the restriction of the wear-resistant layer 432, the cleaning component 43 can be made more wear-resistant and have a longer service life. Under the restriction of the cleaning layer 431, the outer wall of the pump body 2 exposed to the outside can be cleaned, extending the overall service life of the plunger pump.

[0035] Furthermore, the cleaning layer 431 is slidably disposed on the outer wall of the pump body 2. The cleaning layer 431 is made of a flexible material, which allows for cleaning of the outer wall of the pump body 2 while preventing scratches on the outer wall of the pump body 2.

[0036] In addition, the ceramic layer 435 is made of silicon nitride and the anti-corrosion layer 434 is made of anti-corrosion material. Under their constraints, the service life of the cleaning component 43 can be extended.

[0037] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
