Description

Technical Field

[0001] The present invention relates to the technical field of pumping devices, and particularly to a structure of a grease filling channel for a skeleton oil seal of an oil guide bearing in a pumping station. Background Art

[0002] An oil guide bearing is a type of bearing used in rotating mechanical equipment, mainly used in hydro-generators, large motors, and large pump equipment. In pump equipment, the oil guide bearing is installed inside a seal. In order to prevent the lubricating grease inside the seal from leaking and prevent water from entering the seal, skeleton oil seals need to be installed at both ends of the seal.

[0003] The channel between the skeleton oil seal and the seal also needs to be filled with lubricating grease. Since the performance of the grease will decay after long-term use, it is necessary to regularly replace the grease in the channel where the skeleton oil seal is located. The traditional grease filling channel can only be used for transporting and storing grease, and by filling the grease between the skeleton oil seal and the rotating shaft, the friction between the two is reduced and the seal is maintained. However, with the rotation of the rotating shaft, the grease near the contact position between the skeleton oil seal and the rotating shaft is more likely to deteriorate under multiple factors such as temperature, stress, and oxidation. The grease near the side wall of the channel is difficult to flow due to the frictional force of the side wall, resulting in low utilization rate of this part of the grease, uneven use of the grease in the channel, reduced use effect of the grease, and more frequent replacement of the grease. In addition, when replacing the grease in the traditional grease filling channel, the pump needs to be shut down, increasing energy consumption and maintenance costs. Summary of the Invention

[0007] As a further description of the structure of the grease adding channel of the skeleton oil seal of the pump station oil guide bearing in the above technology: two mirror - arranged flow - guiding plates are fixedly connected between the bottom of the separation ring and the annular part, and the two flow - guiding plates are respectively located on both sides of the spiral blade, so that the grease gathers towards the spiral blade when flowing to the lower part of the separation ring.

[0008] As a further description of the structure of the grease adding channel of the skeleton oil seal of the pump station oil guide bearing in the above technology: the bottom of the rotating rod and the spiral blade extends into the inside of the connection head at the bottom of the annular part, and when the rotating rod and the spiral blade rotate, the grease deposited inside the connection head is conveyed upwards.

[0009] As a further description of the structure of the grease adding channel of the skeleton oil seal of the pump station oil guide bearing in the above technology: the transmission assembly includes a housing fixed inside the separation ring, a worm and a worm gear that are rotatably connected inside the housing and mesh with each other, rollers penetrating the top surface of the housing are fixedly connected to both ends of the worm, and the top end of the rotating rod is fixedly connected to the worm gear.

[0010] As a further description of the structure of the grease adding channel of the skeleton oil seal of the pump station oil guide bearing in the above technology: a sealing ring is fixedly connected to the inner wall of the separation ring.

[0011] As a further description of the structure of the grease adding channel of the skeleton oil seal of the pump station oil guide bearing in the above technology: a conveying channel that communicates the connection head with the inner flow channel in the annular part is opened inside the rotating rod.

[0012] As a further description of the structure of the grease adding channel of the skeleton oil seal of the pump station oil guide bearing in the above technology: it further includes a closing unit, the closing unit includes a mounting frame fixed inside the connection head, an upper baffle is fixedly connected inside the conveying channel of the rotating rod, a lower baffle is rotatably connected to the top of the mounting frame, a connecting piece embedded in the lower baffle is fixedly connected to the bottom of the upper baffle, a counterweight is arranged inside the lower baffle, and when the upper baffle drives the lower baffle to rotate and stop through the connecting piece, the lower baffle continues to deflect under the action of inertia to align the holes of the upper baffle and the lower baffle to open.

[0013] In summary, due to the use of the above-mentioned technology, the structure of the oil seal grease channel of the oil guide bearing skeleton of the pump station has the following beneficial effects: During the operation of the pump, the present application uses the power of the rotating shaft to rotate the spiral blades to circulate the grease in the internal channel of the annular member between the inner flow channel and the outer flow channel, so that the grease in various places inside the greasing channel is evenly utilized, and the role of the grease is fully exerted, thereby extending the effective use time of the grease, reducing the frequency of grease replacement, and reducing the cost of grease replacement. At the same time, the rotation of the spiral blades can also output the grease deposited inside the connector, avoiding the accumulation of impurities and grease that may cause blockage inside the connector, so that the grease can be replaced.

[0014] By arranging the delivery pipe, the grease inside the annular member can be replaced without disassembling the pump casing, which simplifies the grease replacement process and saves time and effort in replacing the grease.

[0015] The present application utilizes a separation ring to separate the interior of the annular member into inner and outer flow channels. During the operation of the pump, the deteriorated grease discharged from the inner flow channel can be first sucked out, and then fresh grease can be transported to the outer flow channel. Afterwards, the fresh grease in the outer flow channel will gradually replace the deteriorated grease in the inner flow channel under the action of the grease exchange component, thereby realizing grease replacement without stopping the large pump, allowing the large pump to continue to operate, saving downtime losses and energy losses caused by switching on and off the large pump.

[0016] In the present application, only after the inner flow channel is filled with grease, excess grease will overflow to the outer flow channel through the connector. This design can ensure that there is sufficient grease between the skeleton oil seal and the rotating shaft, avoiding the problem of the liquid level dropping due to evaporation and oxidation loss of grease during long-term use, which will cause the sealing between the skeleton oil seal and the rotating shaft to decrease, thereby improving the sealing and delaying the aging of the skeleton oil seal.

Detailed implementation manners

[0019] Next, the structure of a grease adding channel for a skeleton oil seal of an oil guide bearing in a pump station according to the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0020] As Figures 1 - 9 shown, the structure of a grease adding channel for a skeleton oil seal of an oil guide bearing in a pump station provided by the present invention: includes a pump housing 10, an internal seal 11 is fixedly connected inside the pump housing 10, an oil guide bearing is installed inside the seal 11, both ends of the seal 11 are fixedly connected with mounting cylinders 12, and the mounting cylinders 12 are used to prevent the lubricating oil inside the seal 11 from leaking out and the water inside the pump housing 10 from entering the seal 11. An annular part 14 is fixedly connected to the middle of the mounting cylinder 12, a skeleton oil seal 13 is press-fitted inside the mounting cylinder 12, the pump rotating shaft passes through the seal 11, the skeleton oil seal 13 and the annular part 14, and a seal is maintained between the annular part 14 and the rotating shaft. It further includes: The fat adding mechanism 20 has connectors 21 fixedly connected to both the top and bottom of the annular member 14. A ball valve 22 is fixedly installed on the outer side of the connector 21. A delivery pipe 23 that penetrates and is fixed to the pump housing 10 is fixedly connected between the pump housing 10 and the ball valve 22. The ball valve 22 is used to control the on-off of the delivery pipe 23. The outer end of the delivery pipe 23 is closed by a plug. When it is necessary to replace the grease, the plug is removed and the delivery pipe 23 is connected to the external grease delivery equipment. Through the delivery pipe 23, the grease inside the annular member 14 can be replaced without disassembling the pump housing 10. Delivery pipes 23 are arranged both above and below the annular member 14. The lower delivery pipe 23 is used for injecting grease, and the upper delivery pipe 23 is used for outputting grease, so that the grease fills the internal channel of the annular member 14. The fat adding mechanism 20 includes a connector 24 fixed to the inner wall of the annular member 14. An oil exchange assembly 25 for circulating grease is provided inside the annular member 14. The oil exchange assembly 25 includes a partition ring 251 fixed below the connector 24. An outer flow channel is formed between the annular member 14 and the partition ring 251. The middle part of the inner wall of the partition ring 251 is in contact with the rotating shaft, and the two sides of the inner wall are inclined planes. An inner flow channel is formed between the inclined plane and the skeleton oil seal 13. A sleeve 252 is fixedly connected to the bottom of the partition ring 251. A rotating rod 253 is rotatably connected inside the sleeve 252. A spiral blade 254 is fixedly connected to the rotating rod 253. Through holes are provided at both the top and bottom of the partition ring 251 for communicating the inner flow channel with the connector 24 and the sleeve 252 respectively; The partition ring 251 divides the internal space of the annular member 14 into an inner flow channel and an outer flow channel. The rotating rod 253 and the spiral blade 254 rotate to convey the grease at the bottom of the outer flow channel upward, so that this part of the grease enters the bottom of the inner flow channel through the sleeve 252 and the through hole. The increase in grease in the inner flow channel causes the grease at the top of the inner flow channel to be squeezed, and enters the outer flow channel through the through hole and the connector 24. Then the grease flows downward under the action of gravity until it falls to the bottom of the outer flow channel. In this way, the grease can be circulated and conveyed between the inner flow channel and the outer flow channel.

[0021] Refer to Figure 6 and Figure 7 As impurities will accumulate inside the grease after long-term use, the impurities and grease are likely to block in the connector 21 at the bottom of the annular member 14 under the action of gravity, resulting in the obstruction of grease input when replacing the grease. To solve this problem, the bottom of the rotating rod 253 and the spiral blade 254 extends into the connector 21 at the bottom of the annular member 14. When the rotating rod 253 and the spiral blade 254 rotate, the deposited grease inside the connector 21 is conveyed upward. When the pump is running, the rotation of the spiral blade 254 can evenly mix the impurities and the grease, preventing the impurities from accumulating and blocking in the connector 21.

[0022] Refer to Figure 5, in order to facilitate the transfer of the grease in the outer flow path by the rotating rod 253 and the spiral blade 254, two flow guide plates 26 arranged in a mirror image are fixedly connected between the bottom of the separation ring 251 and the annular member 14. The two flow guide plates 26 are respectively located on both sides of the spiral blade 254, playing a role in guiding the grease. When the grease flows along the outer flow path to below the separation ring 251, it gathers around the spiral blade 254 under the guidance of the flow guide plates 26. After the grease flows onto the spiral blade 254, it is upwardly conveyed by the rotating spiral blade 254.

[0023] Referring to Figure 7 and Figure 8 , in order to synchronize the cyclic transfer of the grease with the operation of the pump, enable the grease to fully exert its effect when the pump is operating, reduce the friction between the skeleton oil seal 13 and the rotating shaft of the pump and improve the sealing performance between the two, a transmission assembly 30 for driving the rotation of the rotating rod 253 by means of the power of the rotating shaft is further included. The transmission assembly 30 includes a housing 31 fixed inside the separation ring 251. A worm 33 and a worm wheel 34 that mesh with each other are rotatably connected inside the housing 31. Both ends of the worm 33 are fixedly connected with rollers 32 that penetrate the top surface of the housing 31 and contact the outer wall of the rotating shaft. When the rotating shaft rotates, the rollers 32 are driven to rotate by friction, and then the worm 33 is driven to rotate. The top end of the rotating rod 253 is fixedly connected with the worm wheel 34. When the worm 33 rotates, the rotating rod 253 is driven to rotate under the transmission of the worm wheel 34. A sealing ring 35 that fits with the rotating shaft is fixedly connected to the inner wall of the separation ring 251. The sealing ring 35 isolates the periphery of the housing 31, so that the grease inside the annular member 14 will not enter above the housing 31, avoiding the occurrence of slipping during the transmission between the rollers 32 and the rotating shaft when they contact the grease.

[0024] Referring to Figure 8 and Figure 9, further comprising a sealing unit 40. The sealing unit 40 includes a mounting frame 41 fixed inside the connector 21. A conveying channel that communicates the connector 21 with the inner flow channel in the annular member 14 is provided inside the rotating rod 253. An upper baffle 42 is fixedly connected inside the conveying channel of the rotating rod 253. The top of the mounting frame 41 is rotatably connected with a lower baffle 43. The upper and lower surfaces of the upper baffle 42 and the lower baffle 43 have the same shape. When the lower baffle 43 deflects 45 degrees relative to the upper baffle 42, the holes in the two are misaligned and closed with each other. A connecting member 44 embedded in the lower baffle 43 is fixedly connected to the bottom of the upper baffle 42. A limiting groove for restricting the rotation angle of the connecting member 44 is provided inside the lower baffle 43, so that the maximum deflection angle of the connecting member 44 and the lower baffle 43 is 45 degrees. A counterweight is provided inside the lower baffle 43. When the rotating rod 253 drives the upper baffle 42 to rotate, the connecting member 44 rotates inside the lower baffle 43. When the upper baffle 42 and the connecting member 44 rotate 45 degrees, the connecting member 44 pushes the inner wall of the limiting groove of the lower baffle 43 to drive the lower baffle 43 to rotate. At this time, the holes in the upper baffle 42 and the lower baffle 43 are staggered and closed with each other. When the upper baffle 42 drives the lower baffle 43 to stop rotating through the connecting member 44, the lower baffle 43 continues to deflect under the action of inertia until the inner wall of the limiting groove of the lower baffle 43 is blocked by the connecting member 44. At this time, the upper baffle 42 and the lower baffle 43 are reset, so that the holes in the upper baffle 42 and the lower baffle 43 are aligned and opened.

[0025] When the rotating rod 253 is in a rotating state, the upper baffle 42 and the lower baffle 43 close the conveying channel inside the rotating rod 253. At this time, when grease is injected through the lower conveying pipe 23, the grease will enter the outer flow channel between the annular member 14 and the partition ring 251 through the gaps between the spiral blades 254 under pressure, and will not enter the inner flow channel through the conveying channel inside the rotating rod 253. Only when the rotating rod 253 and the spiral blades 254 rotate can the grease in the outer flow channel be conveyed to the inner flow channel. At this time, fresh grease enters the inner flow channel from the bottom of the inner flow channel, and the deteriorated grease overflows from the top of the inner flow channel. The deteriorated grease can be pumped out through the connector 21 and the conveying pipe 23 at the top of the annular member 14, and the grease in the inner flow channel can be gradually replaced. During this process, the inner flow channel is always filled with grease, realizing the replacement of grease without stopping the pump.

[0026] When the rotating rod 253 is in a stationary state, the upper baffle 42 and the lower baffle 43 open the conveying channel inside the rotating rod 253. At this time, the grease injected from the connector 21 at the bottom of the annular member 14 can enter the inner and outer flow channels respectively through the conveying channel inside the rotating rod 253 and the gaps between the spiral blades 254, accelerating the replacement of the grease in the inner and outer flow channels.

[0027] Working principle: In the initial state, the inside of the annular part 14 is filled with grease. During the operation of the pump, the rotation of the rotating shaft drives the roller 32 to rotate. Through the transmission of the worm 33 and the worm gear 34, the rotating rod 253 and the spiral blade 254 are driven to rotate, and the grease in the outer flow channel between the separating ring 251 and the annular part 14 is transported through the sleeve 252 and the through hole at the bottom of the separating ring 251 to the inner flow channel between the inclined surface of the separating ring 251 and the skeleton oil seal 13. As the grease in the inner flow channel increases, the excess grease overflows from the through hole at the top of the separating ring 251 and the connector 24 into the outer flow channel. Then, the grease flows downward under the action of gravity and is transported upward again by the spiral blade 254 after being guided by the guide plate 26, realizing the cyclic transportation of the grease between the inner and outer flow channels, enabling the grease in the internal channel of the annular part 14 to be evenly utilized, extending the replacement time of the grease, and the inner flow channel is always filled with grease, which can prevent the sealing performance from decreasing due to the decrease in the grease level between the skeleton oil seal 13 and the rotating shaft; When replacing the grease with the pump running, at this time, the rotation of the rotating rod 253 drives the upper baffle 42 to rotate. The upper baffle 42 drives the connecting piece 44 to rotate inside the lower baffle 43. When the upper baffle 42 and the connecting piece 44 rotate by 45 degrees, the connecting piece 44 pushes the inner wall of the limiting groove of the lower baffle 43 to drive the lower baffle 43 to rotate together. At this time, the holes of the upper baffle 42 and the lower baffle 43 are staggered and mutually closed, closing the inside of the rotating rod 253. At the same time, the grease in the inner and outer flow channels is in a cyclic transportation state. The deteriorated grease overflowing from the inner flow channel and the deteriorated grease in the outer flow channel are continuously pumped out by using an external extraction device through the delivery pipe 23 at the top of the annular part 14, the connector 21, and the connector 24. At the same time, fresh grease is injected by using the lower delivery pipe 23 and the connector 21, so that the grease enters the outer flow channel through the gap between the spiral blades 254. The fresh grease not only pushes the deteriorated grease upward so that the deteriorated grease is pumped out, but also the fresh grease will be transported into the inner flow channel by the spiral blade 254, so that the deteriorated grease in the inner flow channel overflows and is pumped out until all the deteriorated grease in the internal channel of the annular part 14 is replaced with fresh grease; When replacing the grease in the pump machine in the shutdown state, when the rotating rod 253 and the upper baffle 42 stop rotating, the lower baffle 43 continues to deflect under the action of inertia until the inner wall of the limit groove of the lower baffle 43 is blocked by the connecting piece 44. At this time, the upper baffle 42 and the lower baffle 43 are reset, so that the holes of the upper baffle 42 and the lower baffle 43 are aligned and opened. Since the transmission of the worm 33 and the worm gear 34 has self-locking property, when the lower baffle 43 stops rotating, it will not push the connecting piece 44 to cause the upper baffle 42 and the rotating rod 253 to rotate. At this time, fresh grease is injected into the interior of the annular member 14 through the lower conveying pipe 23 and the connector 21. The fresh grease enters the outer flow channel through the gap of the spiral blade 254 and at the same time enters the inner flow channel through the internal conveying channel and the through hole of the rotating rod 253. At the same time, the deteriorated grease is extracted through the upper conveying pipe 23, the connector 21 and the connector 24, realizing the rapid replacement of the grease in the internal channel of the annular member 14.

[0028] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
