Description

Technical Field

[0001] This invention relates to the field of multistage pump technology, and more specifically, to a water-cooled, silent vertical multistage pump. Background Technology

[0002] Vertical multistage pumps are widely used in building water supply, industrial circulating water transportation, urban water supply and drainage and other fields due to their advantages such as high efficiency and energy saving and small footprint. In particular, the demand for silent vertical multistage pumps is increasing in commercial buildings, residential buildings and precision instrument workshops where there are strict requirements for operating noise.

[0003] Currently, the actual operating head of most existing vertical multistage centrifugal pumps is lower than the preset head indicated on the pump nameplate. The head of a vertical multistage centrifugal pump is used to overcome height and resistance. When a high-head multistage centrifugal pump operates at its high head point, its flow rate is the design flow rate. If a high-head multistage pump operates below its preset head, it is equivalent to a decrease in the pump's outlet resistance. At this time, the flow rate of the multistage centrifugal pump will increase, causing the multistage pump to operate under overload. This can easily cause the waterproof motor in the multistage pump to overheat. If the above overload condition is operated for too long, it can even cause the waterproof motor in the vertical multistage centrifugal pump to burn out, posing a certain safety hazard.

[0004] In view of this, we propose a water-cooled, silent vertical multistage pump. Summary of the Invention

[0020] Beneficial effects: One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. Heat is conducted to the cooling plate through the heat-conducting pad on the top of the waterproof motor. Combined with the natural heat dissipation of the fins on the top of the cooling plate and the synchronous heat absorption of the cooling pipes on the side of the waterproof motor, a dual heat dissipation structure is formed. This structure can quickly dissipate the heat generated by the waterproof motor during operation, preventing the performance of the waterproof motor from deteriorating or being damaged due to high temperature accumulation. It ensures that the waterproof motor can work stably at a suitable temperature for a long time, significantly extending the service life of the waterproof motor and the pump body as a whole.

[0021] 2. When water flows through the cooling pipe, it can not only directly carry away the heat absorbed by the waterproof motor, but also conduct the heat adsorbed by the cooling plate through the heat-conducting rod, thus constructing a complete heat transfer link of "waterproof motor - cooling plate - heat-conducting rod - cooling pipe - water flow". This enables rapid heat dissipation through multiple paths, effectively improving the comprehensiveness and uniformity of water cooling heat dissipation, avoiding local overheating, and ensuring the pump's operating efficiency.

[0022] 3. The water flow impacts the blades, driving the gear set to achieve the reciprocating motion of the cooling pipe. When the cooling pipe moves upward, it compresses the elastic compression pump, causing it to spray air into the gap between the fins through the nozzles, accelerating the airflow speed at the fins. This combines natural heat dissipation with forced airflow heat dissipation, further optimizing the heat dissipation effect and efficiency without increasing energy consumption, thus combining energy saving and practicality.

[0023] 4. During the movement of the cooling pipe, the heat-conducting rod will gradually sink into the pipe, dynamically increasing the contact area with the water flow, which can improve the heat exchange efficiency when the cooling pipe moves upward. 5. During the relative sliding process between the heat-conducting rod and the cooling pipe, the scraper set in the groove on the side of the bottom disc of the heat-conducting rod can scrape off the scale attached to the inner wall of the cooling pipe in real time. The sealing gasket fits the pipe wall to ensure that the scraped scale is stored in the groove and eventually collected in the collection tank. This avoids scale accumulation from affecting the heat conduction effect and water flow, reduces the frequency of manual cleaning and maintenance, and ensures the long-term stable heat dissipation and operating performance of the pump body. 6. It achieves active heat dissipation and self-cleaning by relying on the flow energy of water, without the need for additional power consumption, additional waterproof motors or power components, which reduces energy consumption and avoids new noise sources, thus balancing practicality and economy.

The transmission assembly 22 includes a geared disc 221 rotatably connected to the inside of the outlet pipe 18, and two bevel gears 224 rotatably connected to the inside of the rotating groove 24. A blade 222 is provided at the center of the geared disc 221. A drive gear 223 meshes with the side of the geared disc 221. The top of the drive gear 223 is fixedly connected to one of the bevel gears 224. A transmission gear 225 is fixedly connected to the side of the other bevel gear 224. A first driven gear 226 and a second driven gear 228 mesh with the two sides of the transmission gear 225, respectively. A first missing gear 227 is fixedly connected to the side of the first driven gear 226 away from the bevel gear 224, and a second missing gear 229 is fixedly connected to the side of the second driven gear 228 away from the bevel gear 224.

The first missing gear 227 meshes with the double-sided rack 23, and the two bevel gears 224 mesh with each other. When water flows through the blades 222, the blades 222 will drive the gear disk 221 to rotate under the action of the water flow. The rotation of the gear disk 221 will drive the drive gear 223 that meshes with it to rotate. The rotation of the drive gear 223 will drive the transmission gear 225 to rotate through the two bevel gears 224. The rotation of the transmission gear 225 will drive the second driven gear 228 and the first driven gear 226 that mesh with it to rotate. The rotation of the first driven gear 226 will drive the first missing gear 227 that is fixedly connected to it to rotate. The rotation of the first missing gear 227 will drive the double-sided rack 23 that meshes with it to move upward, thereby driving the cooling pipe 11 to move upward, stretching the metal bellows 19 and compressing the elastic compression pump 131. The air in the elastic compression pump 131 will enter the cavity 132 through the ventilation groove 133 and finally be ejected from the gap of the fins 135 through the nozzle 134, thus accelerating the air flow rate at the fins 135.

[0044] This invention provides a water-cooled, silent vertical multistage pump, the working principle and usage process of which are as follows: First, connect the inlet 104 and the outlet pipe 18 to the water supply pipeline. Then, start the waterproof motor 101 to make the pump body 103 work. The water entering from the inlet 104 is pressurized and then transported to the inside of the inlet pipe 17 through the outlet 105. The heat generated by the waterproof motor 101 is conducted to the cooling plate 12 through the heat-conducting pad on its top. The cooling plate 12 dissipates heat through the fins 135 on its top. The cooling pipe 11 located on the side of the waterproof motor 101 also absorbs some of the heat emitted by the waterproof motor 101. When the water entering through the inlet pipe 17 flows through the cooling pipe 11, it will carry away the heat absorbed by the cooling pipe 11. The heat absorbed by the cooling plate 12 will also be conducted to the cooling pipe 11 through the heat conduction rod 14, and the heat conducted on the heat conduction rod 14 will be carried away by the water flow, thus improving the water cooling effect. When water flows through the blades 222, the blades 222 will drive the gear disk 221 to rotate under the action of the water flow. The rotation of the gear disk 221 will drive the drive gear 223 to rotate. The rotation of the drive gear 223 will drive the transmission gear 225 to rotate through the two bevel gears 224. The rotation of the transmission gear 225 will drive the second driven gear 228 and the first driven gear 226 to rotate. The rotation of the first driven gear 226 will drive the first missing gear 227 fixedly connected to it to rotate. The rotation of the first missing gear 227 will drive the double-sided rack 23 to move upward, thereby driving the cooling pipe 11 to move upward, stretching the metal bellows 19 and compressing the elastic compression pump 131. The air in the elastic compression pump 131 will enter the cavity 132 through the ventilation groove 133 and finally be ejected from the gap of the fins 135 through the nozzle 134, which will accelerate the air flow rate at the fins 135 and improve the heat dissipation effect of the fins 135. As the cooling pipe 11 moves upward, the heat-conducting rod 14 will gradually sink into the cooling pipe 11, increasing the contact area between the heat-conducting rod 14 and the water flow. When the heat-conducting rod 14 slides relative to the cooling pipe 11, the scraper 21 located in the groove 205 will scrape off the scale adhering to the inner wall of the cooling pipe 11. Since the sealing gasket 204 is in contact with the inner wall of the cooling pipe 11, the scraped scale will be stored in the groove 205. When the scale accumulates, it will enter the collection tank 203 through the connecting groove 206. When the first missing gear 227 rotates to the position where it disengages from the double-sided rack 23, the second missing gear 229 will rotate to the position where it meshes with the double-sided rack 23 under the drive of the second driven gear 228. At this time, the second missing gear 229 continues to rotate, which will cause the double-sided rack 23 to drive the cooling pipe 11 downward. This cycle is repeated to dissipate heat from the silent vertical multistage pump body 10. The above process is the case when this scheme works on land. Furthermore, this device can also operate underwater. When the waterproof motor 101 is placed underwater, it is surrounded by water. At this time, the noise generated by the waterproof motor 101 is buffered and absorbed by the water, reducing its noise. At the same time, the water surrounding the waterproof motor 101 absorbs the heat generated by the waterproof motor 101 and dissipates it. The water passing through the cooling pipe 11 carries away the heat from the water environment around the waterproof motor 101. When the cooling pipe 11 moves up and down, it achieves the same effect as when used on land, while also disturbing the originally high-temperature water environment around the waterproof motor 101. This prevents the heat generated by the waterproof motor 101 from accumulating locally in the surrounding water, allowing the hot water that has absorbed the heat to mix quickly with the surrounding low-temperature water. This ensures that the surface of the waterproof motor 101 is always in contact with the lower-temperature water, significantly increasing the rate at which the water absorbs heat from the waterproof motor 101 and further enhancing the heat dissipation effect in the underwater scene. Furthermore, the flowing water formed by the disturbance of the cooling pipe 11 can further disperse the sound waves generated by the waterproof motor, preventing the sound waves from propagating in a concentrated manner in still water. At the same time, the flowing water has a better effect on the refraction and absorption of sound waves, which can further weaken the noise propagation intensity on the basis of the original underwater noise reduction, making the quiet operation of the pump body underwater more significant, and suitable for underwater application scenarios with extremely high noise control requirements. Meanwhile, the reciprocating motion of the cooling pipe 11 will cause the elastic compression pump 131 to draw in water and spray water through the nozzle 134, which helps to further disturb the water environment around the waterproof motor 101 and the fins 135, and replace the water in the cavity 132 used to absorb heat, so that all areas of the fins can be in full contact with the low-temperature water, avoiding the problem of uneven heat dissipation of the fins caused by local water stagnation and heating; especially for dense fin areas, the sprayed water can penetrate into the gaps and carry away the accumulated heat, ensuring the overall heat dissipation performance of the fins is stable, and further improving the comprehensiveness of the pump body heat dissipation system; In summary, this device can be used both on land and in water, and is suitable for various scenarios such as building water supply, underwater operations, industrial circulation, and urban water supply and drainage, with a wide range of applications.
