Description

Technical Field

[0001] The utility model relates to the technical field of vibration reduction mechanisms, in particular to a vibration reduction mechanism for a high-pressure water injection pump. Background Art

[0002] A high-pressure water injection pump is a pump that generates high-pressure liquid flow. It is mainly used to inject water or other liquids into equipment processes to complete industrial tasks such as flushing, sand cleaning, rust removal, and mud transportation. High-pressure water injection pumps are widely used in mining, oil fields, construction and other industries due to their reliable performance and diverse applications.

[0003] Especially for the high-pressure water injection pumps used in the oilfield industry, mechanical vibration and internal imbalance may occur, causing the high-pressure water injection pump to shake left and right during use. For example, the friction and movement between the running parts or components inside the high-pressure equipment may cause vibration, or the uneven distribution of liquid mass inside the high-pressure equipment may also cause imbalance during the operation of the high-pressure water injection pump, thereby causing jitter. Therefore, it is necessary to set a vibration reduction mechanism compatible with the high-pressure water injection pump to reduce the vibration of the water pump.

[0004] However, most of the existing vibration reduction methods used by high-pressure water injection pumps use vibration reduction brackets to reduce the vibration of the high-pressure water injection pump. However, the damper on the vibration reduction bracket alone cannot effectively reduce the vibration of the high-pressure water injection pump. Therefore, a special mounting base is required to fix the high-pressure water injection pump, so as to limit the high-pressure water injection pump to prevent the high-pressure water injection pump from not fitting with the mounting assembly, causing the damper to always be in a working state, which reduces the service life of the damper.

[0005] Therefore, the utility model proposes a vibration reduction mechanism for a high-pressure water injection pump. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings in the prior art and to provide a vibration reduction mechanism for a high-pressure water injection pump.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a vibration reduction mechanism for a high-pressure water injection pump, comprising a high-pressure water injection pump mechanism and a bottom plate, the bottom plate is arranged below the high-pressure water injection pump mechanism, mounting brackets are arranged at both ends of the high-pressure water injection pump mechanism, a vibration reduction bracket is arranged at the bottom of the high-pressure water injection pump mechanism between two mounting brackets, a mounting assembly is arranged between the high-pressure water injection pump mechanism and the bottom plate, and a vibration reduction assembly is arranged between the two mounting assemblies;

[0008] The mounting assembly includes a lifting frame, which is connected to a base plate, a sliding limit groove being provided on the lifting frame, a lifting seat being slidably connected to the sliding limit groove, a mounting frame being provided on the top of the lifting seat, the top of the mounting frame being in contact with a mounting bracket, a screw rod penetrating the lifting frame being provided on the lifting seat, and the bottom of the screw rod being rotatably connected to the base plate.

[0009] As a preferred embodiment, the vibration damping assembly includes a vibration damping mounting plate, two of which are provided, and the two vibration damping mounting plates are respectively provided on both sides of the vibration damping bracket, a vibration damping bottom plate is provided at the bottom of the two vibration damping mounting plates, a vibration damping spring sheet is provided at the bottom of the vibration damping bottom plate, and the bottom of the vibration damping spring sheet is in contact with the surface of the bottom plate.

[0010] The beneficial effect of adopting the above-mentioned further scheme is: through the setting of the vibration-damping component, when the high-pressure water injection pump mechanism is in use, the liquid in the middle section of the high-pressure water injection pump mechanism flows, causing the high-pressure water injection pump mechanism to become unbalanced, thereby causing shaking. At this time, when the high-pressure water injection pump mechanism shakes, under the action of the vibration-damping spring, it repeatedly deforms, contracts or expands, supporting the middle section of the high-pressure water injection pump mechanism while playing a buffering and vibration-reducing effect.

[0011] As a preferred embodiment, strip-shaped limit blocks are provided on both sides of the vibration-damping spring sheet on the bottom plate, and first fixing holes are provided on the vibration-damping mounting plate and the vibration-damping bottom plate.

[0012] The beneficial effect of adopting the above further scheme is: through the setting of the strip limit block, the vibration damping component moves downward after being subjected to downward pressure, and at the same time, the two sides of the bottom of the vibration damping spring expand outward. When the vibration damping spring expands to the specified position, under the action of the strip limit block, the expansion distance of the vibration damping spring is limited to prevent the vibration damping spring from being damaged and losing its elasticity due to excessive downward pressure.

[0013] As a preferred embodiment, a mounting plate is provided on the bottom plate at the outer side of the mounting assembly, and a total of four mounting plates are provided, and the four mounting plates are distributed in a rectangular shape.

[0014] The beneficial effect of adopting the above further solution is that by setting the mounting plate, the base plate can be installed and fixed at a specified position through the mounting plate, so that the base plate and the mounting point are an integrated structure.

[0015] As a preferred implementation, the mounting bracket and the mounting frame are both provided with a second fixing hole.

[0016] The beneficial effect of adopting the above further solution is that through the provision of the second fixing hole, the mounting bracket and the mounting frame can be installed and fixed by bolts. The installation method using bolts is more convenient during disassembly than welding.

[0017] As a preferred embodiment, the mounting frame is an L-shaped structure, and the inner wall of the mounting frame is provided with support rods, and there are three support rods in total, and the three support rods are on the same horizontal line.

[0018] The beneficial effect of adopting the above further scheme is: due to the L-shaped structural design of the mounting frame, the mounting frame is easily deformed and bent during use. At this time, the mounting frame is auxiliary supported by the support rod to increase the strength of the support rod and prevent the mounting frame from deforming during use.

[0019] Compared with the prior art, the advantages and positive effects of the utility model are:

[0020] 1. In the utility model, by setting the mounting assembly, the high-pressure water injection pump mechanism can be connected and fixed between the mounting bracket and the base plate according to actual conditions during installation. Further, according to the different positions of the mounting points of the high-pressure water injection pump mechanism, the screw rod is rotated to drive the mounting bracket to move up and down in the sliding limit groove, so that the mounting bracket fits the mounting points of each part of the high-pressure water injection pump mechanism, so that the high-pressure water injection pump mechanism is in a horizontal state, reducing the imbalance caused by the uneven distribution of the internal liquid mass, avoiding the shaking of the high-pressure water injection pump mechanism, and thus improving the stability of the device during use.

[0021] 2. In the utility model, by setting the vibration reduction component, the high-pressure water injection pump mechanism will be unbalanced during operation due to the flow of liquid in the middle section of the high-pressure water injection pump mechanism during use, thereby causing shaking. At this time, when the high-pressure water injection pump mechanism shakes, under the action of the vibration reduction spring, it repeatedly deforms, contracts or expands, supports the middle section of the high-pressure water injection pump mechanism, and has a buffering and vibration reduction effect, thereby improving the practicality of the device when in use.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figure 1-5As shown, the utility model provides a technical solution: a vibration reduction mechanism for a high-pressure water injection pump, comprising a high-pressure water injection pump mechanism 1 and a bottom plate 13, the bottom plate 13 is arranged below the high-pressure water injection pump mechanism 1, mounting brackets 11 are arranged at both ends of the high-pressure water injection pump mechanism 1, a vibration reduction bracket 12 is arranged between the two mounting brackets 11 at the bottom of the high-pressure water injection pump mechanism 1, a mounting assembly 3 is arranged between the high-pressure water injection pump mechanism 1 and the bottom plate 13, and a vibration reduction assembly 2 is arranged between the two mounting assemblies 3; the mounting assembly 3 comprises a lifting frame 32, the lifting frame 32 is connected to the bottom plate 13, a sliding limit groove 321 is provided on the lifting frame 32, a lifting seat 312 is slidably connected to the sliding limit groove 321, a mounting frame 31 is arranged on the top of the lifting seat 312, the top of the mounting frame 31 is in contact with the mounting bracket 11, a screw rod 33 penetrating the lifting frame 32 is arranged on the lifting seat 312, and the bottom of the screw rod 33 rotates It is connected to the base plate 13, and a mounting plate 14 is arranged on the outside of the mounting assembly 3 on the base plate 13. There are four mounting plates 14 in total, and the four mounting plates 14 are distributed in a rectangular shape. The mounting bracket 11 and the mounting frame 31 are both provided with a second fixing hole 34. Through the setting of the mounting assembly 3, the high-pressure water injection pump mechanism 1 can be connected and fixed between the mounting bracket 11 and the base plate 13 according to actual conditions during installation. Further, according to the different positions of the mounting points of the high-pressure water injection pump mechanism 1, the screw rod 33 is rotated to drive the mounting frame 31 to move up and down in the sliding limit groove 321, so that the mounting frame 31 is fitted with the mounting points of each part of the high-pressure water injection pump mechanism 1, so that the high-pressure water injection pump mechanism 1 is in a horizontal state, reducing the uneven distribution of the internal liquid mass, the occurrence of imbalance, avoiding the shaking of the high-pressure water injection pump mechanism 1, and solving the technical problems during the installation of the high-pressure water injection pump mechanism 1.

[0033] Further, such as Figure 1 - Figure 3 As shown: the vibration reduction assembly 2 includes a vibration reduction mounting plate 21, and there are two vibration reduction mounting plates 21 in total, and the two vibration reduction mounting plates 21 are respectively arranged on both sides of the vibration reduction bracket 12, and a vibration reduction base plate 22 is arranged at the bottom of the two vibration reduction mounting plates 21, and a vibration reduction spring piece 23 is arranged at the bottom of the vibration reduction base plate 22, and the bottom of the vibration reduction spring piece 23 is in contact with the surface of the base plate 13. Through the setting of the vibration reduction assembly 2, the high-pressure water injection pump mechanism 1 is in use. Due to the flow of liquid in the middle section of the high-pressure water injection pump mechanism 1, an imbalance phenomenon will occur during operation, thereby causing shaking. At this time, when the high-pressure water injection pump mechanism 1 shakes, under the action of the vibration reduction spring piece 23, it repeatedly deforms, contracts or expands, supports the middle section of the high-pressure water injection pump mechanism 1, and plays a buffering and vibration reduction effect, thereby solving the technical problem of the middle section of the high-pressure water injection pump mechanism 1 shaking when in use.

[0034] The above solution still has the problem that the vibration-damping spring 23 may be deformed and damaged after excessive expansion. Figure 3As shown: in the present embodiment, strip limit blocks 15 are provided on both sides of the bottom plate 13 of the vibration-damping spring piece 23, and first fixing holes 24 are provided on the vibration-damping mounting plate 21 and the vibration-damping bottom plate 22.

[0035] The above solution also has the problem that the mounting frame 31 is easily deformed and bent during use. Figure 4 As shown: In the present embodiment, the mounting frame 31 is an L-shaped structure, and a support rod 311 is provided on the inner wall of the mounting frame 31. There are three support rods 311 in total, and the three support rods 311 are on the same horizontal line.

[0036] Working principle:

[0037] like Figure 1-5 As shown, first, the high-pressure water injection pump mechanism 1 is placed above the bottom plate 13 so that the mounting bracket 11 and the mounting frame 31 are aligned with each other, and the mounting bracket 11 and the mounting frame 31 are further fixed by bolts. At the same time, the vibration-damping mounting plate 21 is clamped on both sides of the vibration-damping bracket 12 and fixed by bolts. The fixing is completed. According to the different installation points of the high-pressure water injection pump mechanism 1, the screw rods 33 on the four mounting components 3 are adjusted respectively. When the screw rods 33 rotate, the mounting frame 31 will be driven to move up and down in the sliding limit groove 321. At this time, the four mounting frames 31 are adjusted to the specified heights respectively, so that the high-pressure water injection pump mechanism 1 is in a horizontal state, reducing the shaking of the high-pressure water injection pump mechanism 1 during use. After the installation is completed, the bottom plate 13 is installed at the specified position through the mounting plate 14, and the high-pressure water injection pump mechanism 1 is turned on to work. When the high-pressure water injection pump mechanism 1 shakes, under the action of the vibration-damping spring piece 23, it repeatedly deforms, contracts or expands, supports the middle section of the high-pressure water injection pump mechanism 1, and plays a buffering and vibration reduction effect.
