New Description: [New Technology Field] This creation is about a submerged vertical fruit puddle with a bubble elimination device, especially a pump that is immersed in a bath and connected with a support tube. The drive motor above the body and the pump immersed in the bath, the long axis of the motor is directly driven through the center of the support tube to directly drive the pump impeller, and the long shaft of the motor rotates in the space of the support chamber, the support tube The liquid in the content chamber space is moved by the rotating shaft to form a natural eddy flow. The centrifugal force generated by the deflation of the ventilating φ disk installed in the space of the branch room is directly guided by the centrifugal force to generate a radial flow to change the original freedom. The funnel portion of the downwardly extending vortex flows in the direction of flow and stops the microbubbles from being directly drawn into the pumping front cover by the back blades. [Prior Art] Please refer to the first figure, the general immersion vertical pump is used for chemical key or residual process to pump strong acid, strong or residual liquid, of which the motor shaft 3 passes through the center of the support tube 1, and the bottom of the motor shaft 3 is directly connected to the impeller hub 52 of the blade 5. The back surface of the blade 5 is provided with a back blade 51 for balancing the axial thrust, and the blade 5 is mounted on the blade 5. In the front cover 4, the front cover 4 opens a pump inlet 44 corresponding to the motor shaft center 3, and a chestnut outlet 45 is opened on the side and is connected to the outlet pipe 43. In actual state, the liquid is sucked by the pump inlet 44 by the blade 5, and the fluid flow After passing through the flow path of the blade 5, it becomes a liquid with pressure and is output by the pump outlet 45. When the pump is running, the rotational tangential speed U' of the sealing sleeve 31 of the motor shaft 3 causes 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 is formed in the center of the scroll, and the flow direction of the free scroll 2 also has a secondary flow line 22 having an rz plane of M330369, and the funnel portion 21 is mixed with the liquid by the suction air 24 to generate microbubbles. The main area of 241 is such that the back blade 51 is applied to attract the microbubbles 241 to flow downwards 'for example, the microbubbles 242 flowing to the rear cover aperture 42 , and the microbubble containing fluid passes through the rear cover aperture 42 and enters the pump 'shell front cover 4 The inside is pressurized into microbubbles 243 having a smaller diameter, and is output from the pump outlet 45 through the outlet pipe 43. The microbubble flow direction 23 also includes flowing from the lower hole 11 of the support tube, the intermediate hole 112 of the support tube, the hole above the support tube, and the like to the bath liquid, and the microbubbles 231 in the grooves may be weak due to the small buoyancy effect of the bubble diameter. The entire in-slot space can be distributed and sucked into the finer microbubbles 244 via the pump inlet 44. These micro-bubbles will pose a greater threat to the process. 0 See the second figure, the seal of the motor shaft 3 The liquid near the surface of the sleeve 31, after receiving the kinetic energy of the rotation of the pump shaft, its rotational flow rate Cu will approach the rotational tangential velocity U of the surface of the sealing sleeve, but the tangential speed of the free vortex

Therefore, the central portion of the free vortex will have a downwardly extending funnel shape due to the low flow rate, as shown in Fig. - that is, the funnel portion 2 is vortexed near the surface of the shaft. The outer surface of the curved surface 2A has a higher potential energy due to the slower flow rate Cu, and the liquid level is higher than the central funnel portion 21 and higher than the liquid of the tank: 29 '. The reason is that the liquid absorbs the axial kinetic energy and the kinetic energy and potential energy according to the flow rate. Turn: Relationship, in line with the principle of energy blame for the law of Bai's efforts. The funnel (4) that is sucked into the free thirst 2 is violently mixed to generate microbubbles 241. See the third figure, the person; Shi, Yi Dantian pump > When the large output pressure of the claw is low and the liquid level of the groove is low, the backing H e, the Ψ 蛀 蛀 蛀 ^ leaf The centrifugal force generated by 51 is sufficient to overcome the pumping pressure of the pump, and the portion of the back blade 51 near the impeller hub 52 produces a sufficient low pressure suction of 7 M330369, which will be introduced into the chamber space 12 via the rear cover aperture 42. The liquid is sucked into the front cover 4 of the pump casing; so that the free vortex 2 liquid level in the chamber space 12 is lowered 'although the support tube 1 is provided with a lower hole ^ ^ to supplement the liquid in the tank to flow in the liquid flow direction 26, but The liquid level outside the vortex curved surface 2A in the chamber space 12 is similar to the liquid level 29 of the tank. At this time, the liquid level of the funnel portion 21 is greatly reduced or even directly reaches the rear cover 41, so that the air 24 passes through the rear cover aperture. 42 is sucked into the pump front cover 4. Therefore, the minimum liquid level is the necessary regulation. • When the liquid level 29 of the δ 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, such as an arrow. As shown, the microbubbles 232 in the direction of liquid flow 26 in the pump casing are drawn in by the pump inlet 44. Referring to the fourth figure, when the pump flow rate is small and the output pressure is high and the tank level 29 is high, the centrifugal force of the back blade 51 is insufficient to balance the high output I force, and the liquid will be on the side of the back blade 51. The rear cover aperture on the rear cover 41 = 2 leakage outflow, the leakage flow direction 262 will flow into the chamber space 12; the liquid level in the space 12 rises, that is, the free vortex 2 rises 'although the branch pipe 1 Open a number of lower holes 11, in the middle, the main opening of the sugar hole 111 (as shown in the fourth figure) 'but the liquid is transmitted by the axis. The outer 2A is combined, the free vortex 2 liquid level will still rise or even the vortex curved body The flying money is sucked onto the lower surface 61 of the supporting plate above the supporting pipe, and the surface of the liquid ring seat 64, the sealing ring 71 and the V-type oil seal 72 is suffocated to generate crystallization and damage the v-type oil seal 72, so that the steam is steamed. control. The motor causes the motor to malfunction 'so, the highest liquid level is necessary. The microbubble 241 generated in the valley to the space 12 along the flow direction 2 3, the M330369 flows from the chamber to the lower hole 11, the intermediate hole 112, and the upper hole U1. The number of bubbles 231, the micro-bubbles 242 that flow through the microchannels 曰0 but flow downwards, are significantly reduced, so that the micro-bubbles 244 that are finer by pumping continue to increase.

These high kinetic energy thrust flow will flow out through the rear cover aperture 42#, the thrust fluid 265 $ into the room air ^ 12 Inside, the liquid in the chamber space 12 is still free to vortex. ^: The lowest water level of the heart funnel portion 21 cannot block the absorption of the thrust fluid. The counter-flushing fluid 266 of the part of the moon will splash upwards. To the support floor ^ support surface axial opening 62, seal ring 71 and ¥ type oil seal 72, the spray liquid will remain crystallized, which will damage the seal ring 71 = oil seal 72, which will cause liquid vapor to penetrate into the motor, causing the motor Damage to bearings and coils. _ This creator has accumulated many years of experience in this industry. It is researched and tested and improved. Now, I have finally created a new type of water-immersed vertical Lipu, which can eliminate the use of products. Disadvantages to improve efficacy. [New content] The reason is that 'the main purpose of this creation is to provide a kind of bubble-eliminating device ^ water-type vertical type (4), which is provided with a disc-shaped elimination 2, an inner liner and an inner liner in the support tube of Lipu. The bubble elimination device can be used to change the flow direction of the streamline from the funnel to avoid the bubble being sucked into the pump by the back blade. Also, when the machine is stopped, the liquid instantaneously reverses and damages the horse 9 M330369. V-type oil seals and seal rings and other devices. Zozuo elaborates on the creation of the following as follows: [Embodiment] Please refer to the sixth figure. 'This creation is mainly based on the installation of a gas-discharging plate 8, an inner liner 81 and an upper inner liner 83 in the vertical pump. The lower lining plate 82 and the like/bubble device, wherein: the deflated disk 8 is a disc structure, and is mounted on the sealing sleeve 31 at the bottom end of the motor shaft 3, and has a upper chamber space 121 above the deflation disk, below Yes, the lower chamber space 123 is adjacent to the pump casing rear cover 41, and the centrifugal force generated when the air-dissipating disc 8 rotates will directly direct the fluid to generate radial flow, that is, change the structure of the funnel portion 21 in which the original free vortex extends downward ( Comparing the first,)' and changing the microbubble flow direction 23 to prevent the bubbles from being directly backed, the sheet 51 is sucked into the pump, and the outer diameter of the getter disc 8 maintains a slight radial gap 422 with the inner diameter of the inner liner 81. The liquid in the chamber space 123 is not convected by the liquid in the chamber space 121 2, so that the microbubbles generated in the space 121 are prevented from entering the lower chamber space 123. The inner liner 81 is a cylindrical perforated rectifying cylinder installed in the valley to the space 12 of the support pipe 1, and the inner liner 8 is divided into the outer chamber space outside the inner liner 81. 122 and the inner space of the inner tube 81. The space (2) and the lower chamber space 123, the upper chamber space 121 is located above the air, the lower chamber space 123 is located below the air trap 8, and the outer valley to the space 122 is located. The space between the inner liner 81 and the support tube J, the micro-gas flow direction 23 of the funnel portion 21 of the free vortex 2 of the chamber space 121 is changed by the air-dissipating disk 8, and the flow direction 23 is directed to the first direction. Turning to the upper helium ring, the microbubbles will flow along the inner side wall of the inner liner 81 and pass through the plurality of inner liner holes 8U on the inner liner 81. This M330369 will rectify and reduce the flow velocity of the gripper. The micro-bubbles 233 increase the buoyancy effect and float up for gas-liquid separation. Compared with the "pore, there are more bubbles due to slower flow rate.

The fluid in the lower chamber space 123 circulates according to the primary flow line 222, but does not attract air to generate microbubbles, and further insulates the entry of microbubbles in the upper chamber space 121, ensuring that the microbubbles do not pass through the rear cover aperture 42. It is sucked into the pump front cover 4. The lower inner liner 82 is a sealed circular orifice plate for fixing the inner liner tube 81, and is installed at the lower portion 812 of the inner liner tube and the upper edge of the lower hole u with respect to the support tube, further separating the outer chamber space 122. The microbubbles 233 are prevented from flowing out of the bath through the lower holes 11 and are also prevented from entering the front cover apertures 42 through the bath flow direction 26 and being sucked into the pump front cover 4. An upper lining plate 83, which is an outer perforated circular orifice plate for fixing the inner liner tube 81, is mounted on the top of the inner dam tube 81 and is connected to the inner diameter of the support tube 1 to block liquid splashing into the upper chamber A sealing device above the space 121 is integrally formed or separated from the lower inner liner 82 and the inner liner 8. Referring to the seventh figure, when the pump flow rate is large and the output pressure is low and the liquid level 29 of the plating tank is low, the liquid in the chamber space 121 on the air venting tray 8 is driven by the original sealing sleeve 31 to rotate the liquid. In addition, the surface of the blow disk 8 is a major factor for liquid driving, and the liquid vortex flow in the upper chamber space 121 becomes a forced vortex 9, at which time the vortex outer curved surface 9A has the highest tangential velocity, and the microbubbles are also intensely generated here. Since the vortex outer curved surface 9A has 11. M330369 • There is the largest movement and the southernmost potential energy, after the bubble is generated, it will pass through the inner liner hole 811 into the outer chamber space 122 and reduce the flow rate for gas and liquid. Separation 'At this time, there will be a large amount of supplementary tank liquid following the flow direction 26, and the hole 11 below the support tube passes through the circumferential gap 423, is attracted by the back blade 51 and enters the pump front cover 4, and the radial gap 422 of the air-dissipating disc is relatively small. The slit has a large flow resistance to reduce the low pressure attractive force of the back blade 51 without the microbubbles being attracted into the pump. Referring to Figure 8, when the pump output flow is low and the output pressure is high and the level of the electroplating bath is high, the high pressure liquid inside the pump will flow from the leakage flow direction 262 through the rear cover aperture 42 to the lower chamber space. In the 123, the liquid flow direction 263 flows backward from the lower hole 11 into the groove, so that no bubble is generated in the lower chamber space 123, and the fluid in the upper chamber space 121 is the free vortex 2, and the center funnel portion 21 is generated. A large number of microbubbles 241 follow the flow of microbubbles and flow toward 23, and flow through the inner liner hole 811. The microbubbles 233 are retained in the outer chamber space 12 2 , and the small bubbles are combined into large bubbles and overflow from the upper hole 111 to become a stop. The large bubbles 234 on the surface of the bath, the large bubbles 234 are limited by the buoyancy _ only stay on the surface of the liquid and cannot be dispersed in the bath, so they are not sucked into the microbubbles by the pump. The upper inner liner 83 is mounted on the top of the inner liner 81, and the central opening diameter of the upper inner liner 83 is smaller than the inner diameter of the inner liner 81 and maintains a radial aperture 424 with the outer diameter of the sealing sleeve 31. When the liquid splashes on the outer side 2A of the curved surface, the upper inner liner 83 can have a shielding effect, and the liquid contacts the support plate lower surface 61, the support plate axial opening 62, the seal ring 71, and the v-type oil seal 72, etc., which can greatly reduce the seal. Damage to the ring 71 and the V-type oil seal 7. The outer hole 831 of the upper inner liner 83 can guide the liquid into the outer chamber space 122 when there is excessive liquid splash. & 12 M330369 β month refers to the ninth figure, when the 'downtime' pipeline, the instantaneous pressure of the south pressure liquid is reversed by the outlet pipe 43 according to the flow direction 271, and flows back into the pump front cover 4 and flows out from the inlet 44 to the high-speed countercurrent liquid. It will also be backed by the back cover 51 through the back cover aperture 42 and the high pressure backwash liquid 265 will flow upward from the rear cover aperture 42. The air is removed from the air venting plate 8, the inner lining 81 and the lower lining 82. The high pressure thrust liquid 265 is caused to flow radially out of the circumferential aperture 423 in the leakage flow direction 262 and flow from the lower orifice 11 into the groove. In summary, the present invention has a water-immersed vertical pump with a bubble-eliminating device, and the system is equipped with a gas-discharging plate, an inner liner, an upper inner liner and a lower inner liner, which can completely and effectively isolate the micro-injection. The bubble is sucked into the pump by the back blade, and the liquid is prevented from being instantaneously backwashed during shutdown to damage the V-type oil seal and the seal ring on the liquid surface; the practical effect is undoubted, and the creation has never been disclosed to the city. Or have been seen in other publications, and have already complied with the provisions of the Patent Law, 爰"
