New description: '[New technical field] This creation is related to the improvement of the shaft seal structure of a submerged vertical pump, especially for immersing in a bath with a support tube to connect the tank The driving motor and the pump immersed in the bath, the long axis of the motor directly passes through the center of the support tube to directly drive the pump impeller, and the long axis of the motor rotates in the space of the support tube, and the space of the support tube is room. The liquid will be driven by the rotating shaft into a natural eddy current and generate a large number of air bubbles. The shaft sealing device installed in the front cover of the pump casing and the lining officer in the supporting pipe can block the air bubbles from entering the pump casing and slow the leakage of the high pressure fluid in the shaft seal. When the pump is shut down, the high-pressure fluid generates a reverse-pressure high-pressure pulse wave generated in the pipeline, and the trapping device can guide the inflow tank to prevent the liquid from splashing upward. [Prior Art] Please refer to the first figure, the conventional flooding vertical pump is used in chemical ore or remnant process to pump strong acid, strong or rotted liquid, of which motor shaft 3 Through the support tube, the center of the motor shaft 3 is directly connected to the impeller hub 52 of the blade 5, and the back of the blade 5 is provided with a back blade for balancing the axial thrust, and the blade 5 is installed in the front cover 4. • The crucible 4 corresponds to the motor shaft 3 opening - the chestnut inlet 44, the side opening a chestnut outlet 45 and engaging the outlet pipe 43; in the actual state, the liquid is sucked by the pump inlet material by the vane 5, and the fluid flows through the vane 5 The flow path becomes a pressurized liquid and is output by the pump outlet 45. When the Lipu is running, the rotational tangential speed U' of the motor shaft and the sealing sleeve 31 of the 3 will drive the liquid in the chamber space 12 to flow in the free vortex 2, and the tangential flow rate 267 is distributed as shown in the second figure. And a funnel portion 21 having a downward extending direction of the M341769 is formed at the center of the scroll, and the flow direction of the free scroll 2 also has a primary flow line 22 of the rz plane, and the funnel portion 21 is mixed with the liquid by the suction air 24 to generate fine bubbles. The main area of 241 is such that the back blade 51 is applied to attract the fine bubbles 241 to flow downward, for example, the fine bubbles 242 flowing to the rear cover aperture 42, and the microbubble-containing fluid passes through the rear cover aperture 42 and enters the pump casing front cover 4. The microbubbles 243 having a smaller diameter are pressed and output from the pump outlet 45 through the outlet pipe 43. The microbubble flow direction 23 also includes a flow through the support tube lower hole 11, the support tube intermediate hole 112, the support tube upper hole m 10, etc., and the microbubbles 231 in these grooves may be weak due to the small buoyancy effect of the bubble diameter. All of the in-slot space is distributed and pumped into the finer microbubbles 24 4 via pump inlet 44, which will pose a greater threat to the process. Referring to the first, as shown in the figure, the liquid near the surface of the sealing sleeve 31 of the motor shaft 3, after receiving the kinetic energy of the rotation of the pump shaft, the rotational flow rate Cu will be close to the rotational tangential velocity U of the surface of the sealing sleeve. However, the rotational flow rate (the tangential speed of the free vortex) Cu decreases as the surface radius r 10 increases beyond the distance from the seal bushing 31, and is proportional to the derivative γ of the radius 1·. Therefore, the central portion of the free flow will have a downwardly extending funnel shape due to the low flow rate, as shown in Fig. 1, that is, the funnel portion 21 which extends downward near the axial surface, and the vortex The outer side of the curved surface has a higher static energy due to the slower flow rate Cu, so that the liquid level is higher than the central funnel portion 21 and higher than the liquid level 29 of the tank. The reason is that the liquid absorbs the axial kinetic energy and the kinetic energy and potential energy according to the flow rate. The conversion relationship, the energy conservation principle of Fukoubai's law of effort. The inhaled air 24 enters the funnel portion 21 of the free vortex = and is vigorously mixed therein to generate fine bubbles 241. Referring to the third figure, when the pump flow rate is high and the output pressure is low and the tank level 29 is low, the centrifugal force generated by the back blade 51 is sufficient to overcome the output pressure of the pump M341769, and the back blade 51 is close to the leaf. A portion of the hub 52 produces sufficient low pressure suction that will draw liquid contained in the two chambers 12 into the front cover 4 of the pump casing via the rear cover aperture 42; such that free vortex 2 in the chamber space The liquid level is lowered, although the support tube is provided with a lower hole u to replenish the liquid in the tank to flow in the liquid flow direction 26, but the liquid level of the 2A outside the vortex curved surface in the chamber space 2 and the liquid level of the tank 29 Similarly, the liquid level of the funnel portion 21 drops drastically even directly to the rear cover 41, so that the inhaled air 24 is sucked into the pump front cover 4 via the rear cover aperture 42. It is necessary to control the minimum level. When the liquid level (minimum liquid level) 29 of the tank is the lowest liquid level, a part of the microbubbles 231 flow into the tank through the microbubble flow direction 23, and a plurality of microbubbles 243 are formed by the inhaled air 24. As indicated by the arrow, in the direction of liquid flow 261 in the pump casing, the microbubbles 232 in the tank are drawn in by the pump inlet 44. μ Refer to the fourth figure. When the pump output flow is low and the output pressure is high and the tank liquid (highest level) 29 is high, the centrifugal force of the (4) piece 51 is not enough. ♦ Balance = output pressure, the liquid will be backed by The back cover of the blade 51 on the side of the blade 茂 的 孔隙 孔隙 孔隙 孔隙 茂 ' ' ' ' 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂 茂The level of the free vortex 2 will rise, although the support tube! There are several lower f holes 1 and a middle hole 112 and an upper hole (1). However, when the liquid receives the rotational kinetic energy of the axis, the free vortex 2 liquid level will rise or even the outer side of the vortex surface will reach the upper side of the support tube. The table below the support plate is φ 6ι, and makes the liquid age seal ring seat 64, seal ring 71 and ¥ type oil seal? 2 On the surface, some of the surface crystallizes and damages the ν-type oil seal 2, causing the rot-resistant strip to ride into the motor to cause motor failure, so the maximum liquid level is necessary for M341769 regulation. The fine bubbles 241 generated in the chamber space 12 flow into the bath from the chamber space 12 through the lower hole 11, the intermediate hole 112, and the upper hole 111 in the flow direction 23, and continue to increase the number of microbubbles 231, and are pumped. The inhaled microbubbles 232 also increase, but the downwardly flowing microbubbles 242 are significantly reduced, so that the finer microbubbles 244 that are pumped and pressurized continue to increase. Referring to the fifth figure, when the machine is stopped, the blade 5 no longer generates high pressure. At this time, the high-pressure liquid accumulated in the pipe system will flow backward from the filter tank and the like of the pipe, and the pump outlet pipe 43 instantaneously flows. Backflushing, these counterflushing fluids 271 will be counter-flushed 281 from pump inlet 44 and also rushed toward the backing blades 51. These high kinetic energy recoil liquids 264 will flow upward through the rear cover apertures 42 and the recoil liquid 265 enters the chamber. In the space 12, the liquid in the chamber space 12 is still free to vortex 2, so that the lowest water level of the scroll center funnel 21 cannot block the kinetic energy of the absorption thrust fluid 265, and some of the thrust liquid 266 will be sprayed upward. Splashing, will spray to the lower surface 61 of the support plate, the pivot opening of the support plate &, 宓 = 』 and the type 7 oil seal 72, etc., the splashed liquid will remain crusting:, the sealing ring 71 and the v-type oil seal 72 In turn, liquid vapor infiltrates into the motor, causing damage to the motor bearings and coils. In order to solve the above problems, relevant solutions have been proposed. Taiwan's new 22nd version "Vertical Pump Sealing Structure - Congruence = Palace Sealing Device, This Patent: Solution: Pipeline High Pressure Liquid Backwash The problem is proposed, ^ in the = 2 Puya does not contain the rotation of the shaft caused by the free vortex generated by the gas, the door of the door ..., the liquid liquid Zhao thrust aspect of the patent maze device two:: collection: liquid M341769 The kinetic energy of the flow is closely related. Generally, the flow energy of the high-pressure thrust fluid can be fully absorbed. However, when the gap becomes larger due to wear, the pressure pulse wave transmission is completely effectively blocked. Therefore, when the process is operated at the liquid level The height difference is smaller than the day's 'this pressure pulse wave will still cause liquid level fluctuations and there is a potential problem of liquid splash. Taiwan's new type M330369 "water-immersed vertical pump with bubble elimination device" patent is related to A new device consisting of a getter disk and an inner liner is designed to solve the bubble problem and the high pressure backlash problem. The solution uses a getter disk to change the free eddy current generated by the rotation of the motor shaft and utilize the porous liner. To separate the bubble from the liquid, to avoid the air bubbles from being dissipated into the liquid tank by the support tube. In addition, the air-dissipating disc is adjacent to the upper part of the pump casing and the bottom of the support tube, and also avoids the suction of the impeller back leaf at a lower liquid level. Rolling problem, but when operating at high pressure (>3bar) and high liquid level (with a liquid level difference of less than 5m), the pulse fluctuation of the high pressure thrust will still pass through the peripheral clearance of the getter disk and the opening of the inner liner The liquid surface splashes. As the production line pursues production efficiency and gradually increases the operating pressure and liquid level, the manager of the production line does not accurately control the tank level and filter system at any time. It also often stores high pressure flow, so that the situation of high liquid level operation still occurs frequently' The high-pressure thrust at high liquid level is very easy to cause the liquid to splash into the V-type oil seal of the motor shaft. Therefore, the damage of the motor is still very common. This creation is also specially improved for the above solution, with an innovative shaft seal structure. Vertical pumping for a variety of applications. In view of this, the creator has accumulated many years of careful research and repeated testing and improvement, and finally created a new type of shaft sealing device for = water vertical pumping. This creation can further enhance the performance of the product. Improve efficiency and improve performance. M341769 [New Content] The main purpose of this creation is to provide a shaft seal structure improvement for a submerged vertical pump, which is provided with a ring-type shaft sealing device, an inner liner tube, an upper inner liner, etc. in the pump casing of the pump. The device, the shaft sealing device can avoid the leakage of the backing blade and the pumping towel to reduce the leakage of the rolling fluid, and the inner liner can limit the direction of the free thirling, separating the bubbles and reducing the splash of the liquid at the high liquid level. The shaft sealing device also prevents the liquid from instantaneously collapsing up during shutdown and damaging the V-type oil seal on the motor side. Zize elaborates on the creation of the following as follows: [Embodiment] Please refer to the sixth figure (4), (8) and the seventh figure (4), (b), the Chuangyi% example t # π water vertical pump shaft Seal Structure & Good Description, Pilot:.

The fixed upper portion 546 of the fixed 'shaft sealing ring 54 is connected with the right ♦ wire of the inner liner tube', and the non-contact shaft seal gap 56 of the cone is maintained between the shaft sealing ring 53 and the shaft sealing ring 54. The shaft sealing ring 53 is provided with a moving ring = portion 531, and the shaft sealing ring 54 is provided with a fixed ring tapered portion 542. Both = cone = gap 561 is used to extend the sealing length of the shaft sealing gap and the kinetic energy of the pulse wave. And a plurality of ring holes 544 are provided on the shaft sealing ring 54 to connect the skin to the Z-work space 122 to guide the thrust pressure/the shaft seal 53 is provided with a moving ring hole 533 to eliminate the accumulation of the M341769 in the shaft seal. Impurities in the gap. An inner liner 81 is a cylindrical structure having a plurality of rectifying holes or openings in the middle portion, and is installed in the chamber space 12 of the support tube 1, and the inner liner 81 = valley to the work space 12 is divided into inner tubes The outer chamber space 12 2 on the outer side of the 81 and the inner chamber space 12 内侧 on the inner side of the inner liner tube 81, the upper portion 813 of the inner liner tube is coupled to the upper inner liner 83, and the lower portion 812 of the inner liner tube is coupled to the shaft seal ring 54. The outer trough space 122 is located in the space between the inner liner 81 and the support tube 1, and the fluid in the inner chamber space 121 generates the free vortex 2 due to the rotation of the motor shaft 3, as shown in the sixth figure (b). The fine bubbles 241 generated by the free vortex 2 flow upward along the inner side wall of the inner liner 81 and pass through the plurality of inner liner holes 811 or the inner tube opening portion 814 on the inner liner 81 to enter the outer valley to the space. 122, at this time, the fine bubble gw will increase the buoyancy effect in the outer chamber space 122 due to the slowing of the flow velocity, and the inner tube lower portion 812 and the shaft seal (4) are fixed on the ring to ensure that the fine bubble 241 is isolated by the shaft sealing device 55.

The second turning point 565 will be in contact with the plurality of moving ring holes 533, and the plurality of moving ring holes 533 will be in communication with the front bushing portion, and the high pressure fluid in the pump 4 will flow in from the moving ring hole 533 to accumulate in the shaft. The impurities of the enclosure 56 are removed by the rear sleeve gap 563. Please refer to the ninth figure. When the machine is stopped, the high-pressure liquid instantaneous flush in the pipeline is flowed by the outlet pipe 43 in the direction of the reverse flow 271, and flows back into the pump front cover & and flows out from the inlet 44, and the high-pressure thrust liquid 265 also The back blade 51 and the f-axis seal gap 56 will be reversely flowed upward, and the high pressure thrust liquid 265 will first absorb some kinetic energy by the front shaft seal gap 562, and then reverse to the tapered portion gap 561 at the first turn of the gap 564. The first turning point 564 will be directly discharged from the ring-shaped hole 544 directly to the outside of the shaft sealing device 55 due to the large change in the momentum direction, as indicated by the liquid flow direction 263, and the residual thrust liquid 265 The kinetic energy and pressure pulse waves will be absorbed by the next tapered portion gap 61. Similarly, at this time, the fluid must be reversed again into the rear bushing gap 563 at the second turning point 565 of the gap, and the portion of the thrust liquid 265 13 M341769 pressure pulse wave is again transmitted by the moving ring hole 533, and the residual thrust liquid 265 Finally, the rear bushing gap 563 will flow out into the content chamber space 12. At this time, the fluid has only a very low kinetic energy and cannot cause splashing of the liquid surface liquid. Please refer to the figure IX. During normal operation, the high pressure body in the front cover 4 of the pump casing will also leak upward from the back blade 51 through the shaft seal gap 56. The high pressure liquid will be absorbed by the front shaft seal gap 562 first. The kinetic energy then flows to the tapered portion gap 561 at the first turning point 564. Before the flow direction changes, the leakage of the moving ring tapered portion 531 of the sealing ring 53 will guide the leaking flow directly from the fixed ring hole. The 544 is directly discharged to the outside of the shaft sealing device 55, and the kinetic energy of the residual flow leakage fluid is absorbed by the tapered portion gap 561 and the second turning portion 5 and the sleeve gap 563. In addition, the rotation of the moving ring tapered portion 531 also provides flow resistance outside the j. Finally, the liquid will flow out and the sleeve gap 563 enters the inner valley chamber f曰1 121 to supplement the fluid flow out due to the free vortex 2 The loss of the chamber space 122, when the fluid has only very low kinetic energy, can not create space 121 liquid level rise and fall. s Please refer to the ninth figure. When the low liquid level is running, the back blade 51 is designed so that it does not generate excessively low negative pressure, so that the liquid is still held in the front cover 4 of the pump casing. The pressure is added to the shaft sealing device 55. Insulation, the fine air bubbles 241 of the content chamber space 121 are not sucked into the flow case front cover 4, and the low pressure liquid in the front cover 4 of the pump casing still flows upward through the shaft seal gap 56, and (4) will be reduced first. 562 absorbs part of the kinetic energy, and then in the tapered portion gap 561, and the rotation of the moving ring tapered portion 531 also directs the leakage fluid to be directly discharged from the fixed ring hole 5 to the outside of the shaft sealing device 55, and the rear bushing gap The small radius and long sealing length of 563 can also prevent the inflow of a large amount of bubbles in the inner chamber space i2i at low liquid level. In addition, the fluid in the front cover 4 of the pump casing flows into the front sleeve portion gap 562. The moving ring hole 533 flows into the gap and the second turning point 14 M341769 5 6 5 ' increases the partial pressure of the rear bushing portion gap 563, and by the rotation of the shaft sealing ring 53, the air bubbles may pass through the rear front bushing gap. The chance and quantity of 562 entering the front cover 4 of the pump casing is greatly reduced, and a small number of bubbles will be cited. The lead is directly discharged to the outside through the ring-shaped hole 544 via the ring-shaped hole 544, and the bubbles float on the surface of the low-level liquid without affecting the process. - Referring to the tenth and (C), the outer liner 71 is a schematic view of the outer liner 71, wherein the middle portion of the inner liner 81 and the lower portion 813, 812 are provided with a plurality of inner liner holes 811'. It may be a circular hole (such as the tenth figure), or it may be an inner tube opening 814 (as shown in the tenth figure) of opening a large opening. As shown in the tenth figure (c), the inner liner 81 may be made. The two parts are separated, wherein the inner tube upper portion 813 and the inner tube lower portion 812 are separated parts. "The middle portion of the tube 81 becomes a complete opening. In summary, the present invention is suitable for water immersion in high and low liquid level operations.
