Description

Technical Field

[0001] The invention relates to the technical field of long-shaft submersible pumps, in particular to a high-stability, wear-resistant long-shaft submersible pump. Background Art

[0002] Long-axis submersible pumps are suitable for conveying various corrosive media such as particles, high viscosity, strong acid, alkali, salt, strong oxidant, etc. New submersible pumps are suitable for conveying various lightweight media such as flammable and explosive media. The housing, outlet pipe and flow-through parts of traditional submersible pumps are all made of corrosion-resistant materials. The motor part is placed on the liquid surface and the pump part is placed below the liquid surface. It has the characteristics of strong corrosion resistance, no blockage, and high temperature resistance.

[0003] At present, when the submersible pump is in use, the driving motor provides kinetic energy to drive the main shaft to rotate at high speed, and the transmission distance of the main shaft is relatively long. During the long-distance transmission process, the main shaft will vibrate to varying degrees. The mechanical vibration generated during the high-speed rotation will directly act on the main shaft, which will aggravate the damage to the main shaft and reduce the service life of the submersible pump. At the same time, due to the high speed of the main shaft, it needs to be lubricated and repaired regularly during use. Once the lubrication is insufficient, it will easily affect the liquid delivery efficiency and increase the loss of the main shaft.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] See also Figure 1-Figure 11 The illustrated embodiment shows a high-stability, wear-resistant long-axis submersible pump, comprising a mounting plate 1, a driving mechanism 6, an anti-shake mechanism 7 and a lubricating mechanism 12.

The lateral vibration of the rotating block 9 is transmitted to the elastic metal ring 8 and dispersed to the dispersion piece 11 for shock absorption.

[0030] See also Figure 1-Figure 8The lubrication mechanism 12 shown in the figure includes a storage box 13 fixedly mounted on the mounting plate 1, and the storage box 13 is used to store lubricating oil. A liquid storage chamber 14 is provided between the device tube 4 and the elastic metal ring 8. When the rotating block 9 rotates, the elastic metal ring 8 is pushed to deform, and the lubricating oil in the liquid storage chamber 14 is squeezed and input into the connecting member 10 for lubrication. When the rotating block 9 stops rotating, the elastic metal ring 8 is reset, and the lubricating oil is drawn from the storage box 13 into a set amount into the liquid storage chamber 14, thereby achieving the purpose of automatic quantitative lubrication during each operation of the equipment.

[0031] See also Figure 1-Figure 5 The driving mechanism 6 shown in the figure includes a mounting frame 43 fixedly mounted on the storage box 13, and a driving motor 44 is fixedly connected to the mounting frame 43. The model of the driving motor 44 is preferably Y80M1-2, and the output end of the driving motor 44 is connected to the main shaft 2 through a coupling, and an impeller 45 is rotatably connected in the fixed cover 5. The bottom end of the main shaft 2 is coaxially fixedly connected to the impeller 45, and the side of the fixed cover 5 is connected to an output pipe 46 fixedly connected to the mounting plate 1.

[0032] In this embodiment, the coupling is driven by the driving motor 44 to make the main shaft 2 rotate at high speed, and the main shaft 2 drives the impeller 45 to rotate, and the liquid is sucked and output through the output pipe 46 to complete the suction and delivery of the liquid. The main shaft 2 and the rotating block 9 are limited by the connecting piece 10, and the friction during the rotation process is reduced. The lateral vibration of the position of the rotating block 9 is transmitted to the elastic metal ring 8 and dispersed to the dispersion piece 11 for shock absorption. When the rotating block 9 rotates, the elastic metal ring 8 is pushed to deform, and the lubricating oil in the liquid storage chamber 14 is squeezed and input into the connecting piece 10 for lubrication. When the rotating block 9 stops rotating, the elastic metal ring 8 is reset, and the lubricating oil is pumped from the storage box 13 into the set amount into the liquid storage chamber 14, so as to achieve the purpose of automatic quantitative lubrication during each operation of the equipment. The device has a simple structure, small rotation resistance and can realize automatic lubrication, which reduces maintenance costs, improves the stability of the equipment during operation, and prolongs the service life of the equipment.

[0033] Embodiment 2:

[0034] See also Figure 1-Figure 9 Embodiment 2 is described. This embodiment further describes Embodiment 1. The dispersion member 11 shown in the figure includes a sliding ring 15 fixedly mounted on the upper and lower sides of the elastic metal ring 8. The sliding ring 15 is slidably connected to the inner wall of the device tube 4 along the vertical direction. A first spring 16 is fixedly connected to the sliding ring 15. A vibration ring 17 is fixedly connected to the first spring 16. A second spring 18 fixedly connected to the inner wall of the device tube 4 is fixedly connected to the vibration ring 17. A transmission member 19 is provided on the rotating block 9 for transmitting vibration to the elastic metal ring 8 during rotation.

[0035] See also Figure 9-11 The transmission member 19 shown in the figure includes a sliding block 20 installed on the rotating block 9, a sliding groove 21 is provided on the rotating block 9, the sliding block 20 is slidably connected to the inner wall of the sliding groove 21 along the horizontal direction, a tension spring 22 fixedly connected to the rotating block 9 is fixedly connected to one side of the sliding block 20, a rolling cavity 23 is provided in the sliding block 20, and a first ball 24 is rollingly connected in the rolling cavity 23.

[0036] See also Figure 7-Figure 11 The connecting piece 10 shown in the figure includes a threaded ring 25 fixedly installed at the upper and lower ends of the device tube 4, and a connecting tube 26 is connected to the inner thread of the threaded ring 25. The upper and lower sides of the rotating block 9 are provided with a first rolling groove 27, and a plurality of groups of second balls 28 are rollingly connected in the first rolling groove 27. The bottom end of the connecting tube 26 is provided with a second rolling groove 29 that can be rollingly connected to the outer wall of the second ball 28.

[0037] In this embodiment, the connecting tube 26 is screwed into the threaded ring 25 so that the second rolling groove 29 fits the surface of the second ball 28, and then the device tube 4 is docked with the docking tube 3 for installation. When the main shaft 2 rotates at a high speed, the main shaft 2 and the connecting tube 26 are limited by the second ball 28, and the second ball 28 rolls between the first rolling groove 27 and the second rolling groove 29, which greatly reduces the friction during the rotation of the main shaft 2. As the rotating block 9 rotates at a high speed, the centrifugal force on the sliding block 20 increases, and the tension spring 2 2 is gradually stretched, and the first ball 24 gradually approaches the side wall of the elastic metal ring 8 and squeezes the elastic metal ring 8. At this time, the lateral vibration of the main shaft 2 and the rotating block 9 can be transmitted to the elastic metal ring 8, so that the elastic metal ring 8 can be stretched and retracted in the longitudinal direction, pushing the sliding rings 15 on the upper and lower sides to rise and fall, and then transmitted to the vibration ring 17 through the first spring 16, and the second spring 18 is used for shock absorption. Finally, the vibration is dispersed into the longitudinal force along the main shaft 2 through the vibration of the vibration ring 17, thereby reducing the damage to the lateral swing of the main shaft 2.

[0038] It should be noted that when the first ball 24 fits with the elastic metal ring 8, the first ball 24 evenly distributed around will tightly contact the elastic metal ring 8. The elastic metal ring 8 is made of an elastic metal sheet with a thickness of about 1 mm, and is resisted by the hydraulic oil in the side liquid storage chamber 14. It will not produce excessive plastic deformation and will rebound and reset after the rotating block 9 stops rotating. The first ball 24 rolls on the elastic metal ring 8 in contact, which can reduce the friction between the sliding block 20 and the elastic metal ring 8, and can effectively increase the supporting force of the rotating block 9 on the surroundings and reduce the lateral jitter of the rotating block 9. As the rotation speed of the rotating block 9 decreases, the centrifugal force weakens, and the tension spring 22 pulls back, which can drive the sliding block 20 to slide in the opposite direction to the inside of the rotating block 9 for reset.

[0039] Embodiment 3:

[0040] See also Figure 2-Figure 11 Embodiment 3 is described. This embodiment further describes embodiment 1. The lubrication mechanism 12 shown in the figure also includes a plurality of first pipes 30 fixedly installed in the device pipe 4. An annular groove 31 capable of communicating with the first pipe 30 is provided on the side of the connecting pipe 26. A plurality of second pipes 32 for connecting the annular groove 31 with the second rolling groove 29 are provided in the connecting pipe 26. A third pipe 33 connected with the first rolling groove 27 is provided on the rotating block 9. A connecting groove 34 for connecting the third pipe 33 with the sliding groove 21 is provided on the sliding block 20. A fourth pipe 35 for connecting the sliding groove 21 and the rolling cavity 23 is provided on the sliding block 20.

[0041] See also Figure 2-Figure 11 The lubrication mechanism 12 shown in the figure also includes a delivery pipe 36 connected to the storage box 13, and the delivery pipe 36 is connected to the multiple groups of liquid storage chambers 14. A one-way valve 37 is provided in the delivery pipe 36 for controlling the one-way input of lubricating oil from the storage box 13 into the delivery pipe 36. A control member 38 for controlling the flow direction of the lubricating oil is provided in the first pipeline 30. The control member 38 includes a first fixed ring 39 and a second fixed ring 40 fixedly installed in the first pipeline 30. The first fixed ring 39 is located on the side close to the liquid storage chamber 14. A third spring 41 is fixedly connected to the second fixed ring 40, and a blocking ball 42 for blocking the through hole of the first fixed ring 39 is fixedly connected to the third spring 41.

[0042] In the present embodiment, when the first ball 24 contacts and squeezes the elastic metal ring 8, the lubricating oil in the liquid storage chamber 14 will be pushed toward the sealing ball 42 through the first fixing ring 39, and then input into the first pipe 30 through the second fixing ring 40, and then input into the annular groove 31 along the first pipe 30, and then enter the second pipe 32 and the second rolling groove 29 to be smeared on the outer wall of the second ball 28 to lubricate the second ball 28, and then input into the sliding groove 21 through the first rolling groove 27, the third pipe 33, and the connecting groove 34 to lubricate the sliding of the sliding block 20, and then enter into the rolling chamber 23 through the fourth pipe 35 to lubricate the rolling of the first ball 24, which is convenient and efficient to operate.

[0043] It is worth noting that: when the main shaft 2 and the rotating block 9 stop rotating, the first ball 24 releases the resistance to the elastic metal ring 8, and the elastic metal ring 8 rebounds and resets, and the lubricating oil in the storage box 13 can be drawn into the delivery pipe 36 through the one-way valve 37 and input into the liquid storage chamber 14. At this time, the blocking ball 42 is pushed by the third spring 41 to block the through hole of the first fixed ring 39, thereby avoiding the backflow of the lubricating oil. During each rotation and stop of use, the lubricating oil is automatically added and maintained once, without manual control. The operation is convenient and efficient, and the amount added each time is relatively uniform. This amount can be controlled by the capacity design of the liquid storage chamber 14 and the elastic design of the elastic metal ring 8, so that the amount of lubricating oil delivered each time is controlled to 1-2 ml, which not only ensures that the internal parts can be effectively lubricated, but also avoids excessive addition of lubricating oil.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
