Description

Technical Field

[0001] The invention relates to the technical field of centrifugal pumps, and in particular to an intelligent pump room for secondary water supply equipment. Background Art

[0002] Secondary water supply refers to the storage and pressurization of urban public water supply or water supplied by self-built facilities by units or individuals and then supplied to users through pipelines. For high-rise buildings, due to the lack of pressure in municipal water supply pipelines, it is usually necessary to pressurize the municipal water supply for the second time so that the tap water can reach the upper floors and be used by high-rise users. Secondary water supply is the only way to supply water to high floors. Secondary water supply equipment is mainly composed of air pressure tanks, water pumps, water supply tanks, water supply pipe groups and control cabinets, and is centrally installed in a pump room with dustproof protection. The water pump is the core component of the water supply equipment, and most of them are centrifugal pumps with large flow and high head.

[0003] There are many technical defects in the existing pump room and centrifugal pump when they are in use. First, at high temperature nodes in summer, the pump room in the external environment faces heat dissipation problems. Relying solely on cooling fans and ventilation cannot solve the high temperature problems caused by the operation of water supply equipment, which can easily cause frequent alarms (control cabinets) or even damage to the equipment; second, after a long period of use, precipitated impurities will form on the inner surface of the water supply tank. When these precipitated impurities fall off, they will be sucked into the water inlet pipe. After the water flow is accelerated, they will enter the centrifugal pump cavity, collide with the impeller, generate noise, and easily damage the impeller; third, the impeller generates a large centrifugal force when it rotates at high speed. Under the action of centrifugal force, the water reduces the pressure at the inlet of the pump, that is, the water inlet pipe. When the inlet pressure reaches the water vaporization pressure at this temperature, the water begins to vaporize to form bubbles. In this way, the bubbles formed in the moving water flow with the liquid. When the static pressure of the bubble exceeds the saturated vapor pressure, the bubble collapses rapidly, and the surrounding water moves toward the center of the bubble at high speed, forming a high-frequency water hammer effect, which can generate a pressure of tens of thousands of kilopascals, hitting the surface of the impeller. It also generates noise and vibration. When the bubble generation and collapse process is repeated, it will damage the impeller surface in this area, causing the pump flow rate to decrease, the head to drop, and the efficiency to decrease.

[0004] To sum up, considering that the existing facilities cannot meet the work needs, we propose an intelligent pump room for secondary water supply equipment. Summary of the invention

[0024] The present invention provides an intelligent pump room for secondary water supply equipment through improvement, which has the following significant improvements and advantages compared with the prior art:

[0025] A high-temperature radiator is designed with the help of the power of a centrifugal motor. When the drive shaft rotates, it drives the roller to rotate at high speed through a chain transmission. The sprinkler on the centrifugal sprinkler first passes downward through the cooling water trough, and uses the infiltration port at the end to scoop up the cooling water in the upper layer of the trough. The water in the water collecting chamber undergoes centrifugal motion and is transformed into droplets from the fine sprinkler holes and thrown out. When the centrifugal sprinkler passes through the sprinkler port, the droplets move from the sprinkler port into the water supply room. At this time, several groups of heat dissipation fans are started to generate horizontal wind force, carrying the moving droplets to disperse and flow to various places inside the water supply room, absorbing heat and cooling the internal air of the entire pump room, achieving the effect of heat dissipation in high temperature seasons, with long duration and better effect.

[0026] The driving rod rotates with the high-speed movement of the head. During the rotation process, several groups of flexible crushers are caused to move against the action of the water flow. On the one hand, when precipitated impurities move to this area with the water flow, they will randomly collide with the crushing blades on the flexible rope, which can crush the precipitated impurities and reduce their movement speed, thereby reducing damage to the impeller and reducing noise.

[0027] On the other hand, based on the dual effects of water flow and centrifugal force, the movement area of ​​the flexible rope is close to the impeller. Therefore, the breaking blade will be used to break the bubbles as soon as they are generated, and the bubbles will be eliminated in time to prevent a large number of bubbles from entering the impeller area and causing a series of hazards, thereby achieving a protective effect. In addition, the flexible breaker is based on a flexible rope, which is light in material and occupies a small volume. During movement, it has little interference with the flow of water and will not affect the water supply work. It has a high degree of intelligence.

[0028] A self-rotating knife is used instead of a crushing blade. The annular knife seat on the self-rotating knife will rotate around two sets of inner bearings due to the unidirectional impact of the water flow. The knife teeth accelerate and extend out of the receiving groove in turn. The crushing force is stronger for the precipitated impurities or bubbles passing through, and the performance is improved with the help of the water flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Among them, supports are arranged on the outer sides of the centrifugal motor 11, the transmission shaft 13 and the pump housing 14, and a protective cover is arranged on the outer side of the centrifugal motor 11 to play a protective role.

[0045] Furthermore, the transmission shaft 13 is sleeved with a first sprocket 16 in the area between the bearing seat 12 and the pump housing 14. Figure 1 and 2 shown.

[0046] Furthermore, a high-temperature radiator 7 is provided at the lower left corner of the water supply chamber 2 (the high-temperature radiator 7 can be disassembled when not in use). Figure 2 shown.

[0047] Specifically, the high temperature radiator 7 includes an annular protective sleeve 71, an inner cavity 72, a water sprinkling port 73, a cooling water tank 74 and a rotating roller 75. Figure 4 and 5 shown.

[0048] In this embodiment, an inner cavity 72 is opened inside the annular protective sleeve 71, and a water sprinkling port 73 connected to the inner cavity 72 is opened at the top of the annular protective sleeve 71. The width of the water sprinkling port 73 is determined according to actual conditions. A cooling water trough 74 is extended downward from the bottom of the annular protective sleeve 71. The cooling water trough 74 can be excavated 1-2 meters underground to form surface cooling water, and can also be set as a pool. A roller 75 is rotatably set in the middle of the inner cavity 72.

[0049] Furthermore, the high temperature radiator 7 further includes a drain hole 76, a fixed bearing 77, a shaft portion 78, a second sprocket 79 and a centrifugal sprinkler 8, as shown in FIG. Figure 4 and 5 shown.

[0050] In this embodiment, the roller 75 is a hollow structure, including several groups of drainage holes 76, which play the role of reducing weight and diverting water downward. The two ends of the roller 75 are fixed by fixed bearings 77 and the inner wall of the annular protective sleeve 71, and the roller 75 rotates around the two groups of fixed bearings 77.

[0051] In this embodiment, a shaft 78 is provided at one end of the roller 75 extending to the outside of the annular protective sleeve 71, and a second sprocket 79 is sleeved on the shaft 78. The second sprocket 79 and the first sprocket 16 are connected by a chain 17. The sizes of the second sprocket 79 and the first sprocket 16 are determined according to actual needs. A plurality of groups of centrifugal sprinklers 8 moving in the inner cavity 72 are evenly distributed on the outer surface of the roller 75.

[0052] Specifically, the centrifugal sprinkler 8 includes a connecting rod 81, a sprinkler tube 82, a water collection chamber 83, a permeation port 84, and a fine sprinkler hole 85. Figure 5 and 6 shown.

[0053] In this embodiment, one end of the connecting rod 81 is fixed to the outer surface of the roller 75, and the other end of the connecting rod 81 is connected to a sprinkler 82. The sprinkler 82 moves in a circle near the inner wall of the annular protective sleeve 71. The sprinkler 82 enters the cooling water tank 74 during the circular movement. A water collecting chamber 83 is provided inside the sprinkler 82, and penetration ports 84 are symmetrically provided at the center positions of both ends of the sprinkler 82. A plurality of groups of fine sprinkler holes 85 are evenly provided on the side of the outer cylinder surface of the sprinkler 82 away from the connecting rod 81. The fine sprinkler holes 85 are used to convert water into droplets similar to atomization to improve its fluidity.

[0054] The outer side of the pump room 1 is provided with a fan unit 54, which includes a plurality of cooling fans 55. The inner side of the pump room 1 is provided with a guide groove 56 for acting on the cooling fans 55. The guide groove 56 is located obliquely above the high-temperature radiator 7. Figure 1 and 2 shown.

[0055] Among them, the other side of the pump room 1 is provided with a ventilation grille 57, which plays the role of ventilation and heat dissipation. Figure 1 and 2 shown.

[0056] Furthermore, a centrifugal pump chamber 20 is provided inside the pump housing 14, and the other end of the transmission shaft 13 extends into the centrifugal pump chamber 20 and is provided with an impeller shaft 21, a rear cover plate 22 is sleeved on the impeller shaft 21, and a plurality of impellers 23 are installed on the rear cover plate 22 (it can also be provided as a multi-stage impeller combination to become a multi-stage centrifugal pump), and a head 24 is provided at the end of the impeller shaft 21, such as Figure 7 shown.

[0057] Furthermore, a water outlet channel 58 is connected to the cross-section of the pump housing 14, and a diffuser 59 is installed at the upper end of the water outlet channel 58. The upper end of the diffuser 59 is connected to the lower end of the water outlet main pipe 51 through a flange, and the outer side of the diffuser 59 is connected to the water inlet pipe 5 through the ejector pipe group 53. The ejector pipe group 53 drains part of the water in the diffuser 59 into the water inlet pipe 5, so that the fluid pressure at the inlet of the impeller 23 increases, thereby avoiding cavitation. Figure 3 and 7 shown.

[0058] The upper end of the water outlet main pipe 51 is connected to a water pipe 52. Figure 1-3 shown.

[0059] Furthermore, a control cabinet and a gas tank are also provided in the pump room 1.

[0060] When this embodiment is in use, when the equipment is used at high temperatures in summer, the centrifugal motor 11 is started, driving the transmission shaft 13 to rotate, causing several groups of impellers 23 to perform centrifugal motion, and using the water inlet pipe 5 to suck water temporarily stored in the water storage tank 3. Through the action of the impeller 23, the water in the centrifugal pump chamber 20 is discharged at high speed toward the water outlet channel 58, enters the water outlet main pipe 51, and is supplied to the tap water pipes 52 of high-rise residents.

[0061] When the transmission shaft 13 rotates, the first sprocket 16 causes the second sprocket 79 on the high-temperature radiator 7 to rotate synchronously through the chain 17, driving the roller 75 to rotate at a high speed, causing the multiple groups of centrifugal sprinklers 8 on the roller 75 to make centrifugal circular motions. The sprinkler 82 on the centrifugal sprinkler 8 first passes downward through the cooling water tank 74, and uses the penetration port 84 at the end to scoop up the cooling water in the upper layer of the tank and enter the water collection chamber 83. When the sprinkler 82 continues to move at a high speed, the water in the water collection chamber 83 makes a centrifugal motion and is concentrated to the position of the fine sprinkler hole 85. The water moves and turns into droplets from the fine water sprinkling holes 85 and is thrown out. Most of the droplets hit the wall of the inner cavity 72 and are finally diverted back to the cooling water tank 74. When the centrifugal sprinkler 8 passes through the water sprinkling port 73, the droplets move from the water sprinkling port 73 into the water supply chamber 2. At this time, several groups of heat dissipation fans 55 are started to generate horizontal wind force, which carries the moving droplets to disperse and flow to various places inside the water supply chamber 2, absorbs heat and cools the internal air of the entire pump room 1. Finally, most of the droplets are vaporized and discharged from the ventilation grille 57 to achieve the effect of heat dissipation in high temperature seasons. Embodiment 2

[0062] On the basis of the first embodiment, on the one hand, after the water storage tank 3 has been used for a long time, precipitated impurities will be formed on the inner surface. When these precipitated impurities fall off, they will be sucked into the water inlet pipe 5, and will enter the centrifugal pump chamber 20 after the water flow is accelerated, and collide with the impeller 23, generating noise, and easily damaging the impeller 23. On the other hand, the impeller 23 generates a large centrifugal force when rotating at a high speed. Under the action of the centrifugal force, the water reduces the pressure at the inlet of the pump, i.e., the water inlet pipe 5. When the inlet pressure reaches the water vaporization pressure at this temperature, the water begins to vaporize to form bubbles. In this way, the bubbles formed in the moving water flow with the liquid. When the static pressure of the bubble exceeds the saturated vapor pressure, the bubble collapses rapidly, and the surrounding water moves toward the center of the bubble at a high speed, forming a high-frequency water hammer effect, which can generate a pressure of tens of thousands of kilopascals, hitting the surface of the impeller 23, and generating noise and vibration. When the bubble generation and collapse process is repeated, the surface of the impeller 23 in this area is damaged, which reduces the pump flow, reduces the head, and reduces the efficiency. In order to solve the above problems, we have the following design, such as Figure 7-8 shown.

[0063] Specifically, a driving rod 25 is horizontally welded at the middle position of the head 24, and the driving rod 25 extends toward the inside of the connecting cover 15. Figure 7 shown.

[0064] Among them, a plurality of groups of flexible breakers 9 are evenly distributed on the driving rod 25, such as Figure 7 shown.

[0065] Specifically, the flexible crusher 9 includes a flexible rope 91, a rope loop 92 and a crushing blade 93. Figure 8 shown.

[0066] In this embodiment, the flexible rope 91 has flexible deformation capability and is light in weight. One end of the flexible rope 91 is tied to the driving rod 25. Several groups of rope loops 92 are sleeved on the flexible rope 91. A crushing blade 93 is arranged outside the rope loop 92 facing the water inlet pipe 5, which is used to positively crush the flowing precipitated impurities or bubbles.

[0067] When this embodiment is in use, the driving rod 25 rotates with the high-speed movement of the head 24. During the rotation, several groups of flexible breakers 9 are caused to move to overcome the action of the water flow. On the one hand, when precipitated impurities move to this area with the water flow, they will randomly collide with the crushing blades 93 on the flexible rope 91, which can not only crush the precipitated impurities, but also reduce their movement speed, thereby reducing damage to the impeller 23; on the other hand, based on the dual effects of water flow and centrifugation, the movement area of ​​the flexible rope 91 is close to the impeller 23, so the crushing blades 93 will be used to crush the bubbles as soon as they are generated, thereby preventing a large number of bubbles from entering the impeller 23 area and causing a series of hazards. Embodiment 3

[0068] like Figure 9-10 As shown, specifically, the flexible breaker 9 includes a flexible metal strip 30 , a receiving groove 31 and a self-rotating knife 33 .

[0069] In this embodiment, one end of the flexible metal strip 30 is tied to the driving rod 25 , and a plurality of groups of receiving grooves 31 are evenly distributed inside the flexible metal strip 30 . The receiving grooves 31 are open outward, and a self-rotating knife 33 is installed in each group of receiving grooves 31 .

[0070] Furthermore, the self-rotating knife 33 includes a knife shaft 40, an inner bearing 41, an annular knife seat 42 and a knife tooth 43. Fig.10 shown.

[0071] In this embodiment, both ends of the knife shaft 40 are fixed by an inner bearing 41 and the inner wall of the accommodating groove 31 , and an annular knife seat 42 is sleeved on the outer side of the middle part of the knife shaft 40 .

[0072] In this embodiment, a plurality of groups of blade teeth 43 are evenly distributed around the outer surface of the annular blade seat 42. The blade teeth 43 extend out of the accommodating groove 31 during movement. The installation direction of the blade teeth 43 is consistent with the direction of water flow, ensuring that the water flow can drive the rotating blade 33 to rotate at high speed.

[0073] When this embodiment is in use, a self-rotating knife 33 is used to replace the crushing blade 93 in the second embodiment. The annular knife seat 42 on the self-rotating knife 33 will rotate around the two sets of inner bearings 41 due to the unidirectional impact of the water flow, and the knife teeth 43 will accelerate and extend out of the accommodating groove 31 in turn, so that the crushing force for the precipitated impurities or bubbles passing through is stronger.

[0074] 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.

[0075] 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.
