Description

Technical Field

[0001] The present invention relates to the technical field of water flow transportation, in particular to a water pump. Background Art

[0002] A water pump typically consists of a motor, impeller, pump body, and pump head. The motor and impeller are housed within the pump body, which is connected to the pump head. The pump head has an inlet connected to the inlet pipe to guide water into the pump body. When the motor is running, it drives the impeller to rotate, creating negative pressure, which draws water in through the inlet. After passing through the channel connecting the pump head and pump body, water enters the impeller chamber where it is pressurized and is then ejected from the pump's outlet, completing its liquid transport function.

[0017] Compared with the prior art, this embodiment has the following outstanding and beneficial technical effects:

[0018] An integrated pump head is installed inside this embodiment, which is connected to the pump inlet, pump outlet and water injection port of the water pump. It adopts an integrated structure, is stable in structure, and is easy to install; it cooperates with the end mounting shell to form an impeller mounting cavity, and the impeller mounting cavity and the guide body component inside it cooperate to form a water-gas separation chamber, and a drainage curved surface 1 is provided in the slow flow cavity of the water-gas separation chamber. Water flows into the slow flow cavity from the water outlet, and the drainage curved surface 1 diverts the water flow to the water outlet direction of the slow flow cavity to avoid the water flow directly impacting the parts inside the pump body, reducing vibration, and helping to better protect the parts inside the pump body. The water blocking ring causes the flowing water to collide with the components in the pump body, thereby reducing the water flow speed and accelerating the water-gas separation, thereby achieving a better water-gas separation effect.

[0019] Furthermore, a reflux channel is provided on one side of the water-gas separation chamber, and a self-priming valve is provided in the reflux channel, which controls the cutoff or conduction of the reflux channel by the self-priming valve. When the pump body is pumping air, the inhaled water flow is detected by detecting the pressure change in the pump body to detect whether it meets the standard. If it meets the standard, the pump body operates normally, the self-priming valve is closed, the reflux channel is cut off, and the water body cannot flow back, thereby reducing the energy loss of the pump body and improving the energy utilization rate of the pump body; if it does not meet the standard, when there is more gas in the water flow, the internal pressure of the pump body is small, the self-priming valve opens and the reflux channel is conducted; the water flow accumulates in the water-gas separation chamber and is re-delivered by the impeller through the reflux channel. At the same time, the pump inlet also inhales water flow, and the water flow in the pump body gradually increases until the water flow in the pump body meets the set standard, the self-priming valve closes, and returns to the normal supply state; wherein, an elastic member is provided on the valve stem of the self-priming valve, and an electromagnetic coil part is provided at the lower part of the self-priming valve. When the electromagnetic coil part is energized, it cooperates with the elastic member to keep the elastic member in an open state.

[0020] Furthermore, the guide body assembly is provided with a plurality of impeller chambers, and the impeller chambers are provided with impeller assemblies. The impeller assemblies are all fixed on the main shaft of the pump body, and the main shaft drives the impeller assembly to rotate. A separable sealing component installation cavity is formed between the front side wall of the impeller chamber and the ring cover. A sealing component is sleeved in the sealing component installation cavity. The position of the sealing component corresponds to the upper side of the middle sleeve part of the impeller. When the sealing component is subjected to a certain external force, it can move in the sealing component installation cavity. That is, the water pump is in the running-in period for the first few times when the water pump is used. During the running-in period, during the rotation of the impeller, the middle sleeve part of the impeller may hinder the sealing component. At this time, the impeller will push the sealing component to rotate in the sealing component installation cavity until there is no obstruction between the sealing component and the impeller, thereby ensuring that the gap reserved between the middle sleeve part of the impeller and the sealing component is minimized, thereby better controlling the situation where part of the water flow in the next-stage impeller chamber flows back through the gap to the impeller chamber of the previous stage, resulting in a decrease in the pressure of the water outlet, further improving the working efficiency of the water pump; wherein, the sealing component is preferably a ceramic ring or an engineering plastic ring with good wear resistance.

[0021] Furthermore, the pump casing of this embodiment is an upper casing and a lower casing that are installed by snapping together. The overall assembly method of the casing is stacked in sequence. The upper casing and the bottom casing are assembled first, and then the left and right side casings are installed. The left and right side casings are installed on both sides of the upper casing and the bottom casing by screws and nuts. Combined with the structure of the integrated pump head, the overall structure of the present invention is simpler, and installation and disassembly are simple and convenient, which saves time and effort and has high disassembly efficiency.

[0070] Furthermore, the water-blocking ring 603 is provided with an embedding groove 623 and an avoidance hole 633. When the terminal guide body 504 is installed on the guide body assembly 5, the upper end of the drainage curved surface 1 524 is embedded in the embedding groove 623. In addition, a hollow second fixing column 584 is provided in the slow flow chamber 601. The second fixing column 584 is integrally provided with the drainage curved surface 1 524 to make its structure more stable. A first fixing column 505 is provided on the outside of the impeller chamber 501. When the terminal guide body 504 is installed on the guide body assembly 5, the second fixing column 584 passes through the avoidance hole 633 and extends out of the surface of the water-blocking ring 603. The first fixing column 505 is inserted into the second fixing column 584.

[0071] Furthermore, mounting holes are evenly provided at corresponding positions on the circumference of the terminal guide body 504 and the circumference of the terminal shell 4, and the mounting holes correspond to the third mounting holes 3121 on the open port 312. The circumferential edge of the terminal guide body 504 is located between the edge of the open port 312 and the circumferential edge of the terminal shell 4, and the integrated pump head 3, the terminal guide body 504 and the terminal shell 4 are installed by screws and nuts; wherein, the circumferential side of the outer ring portion 514 abuts against the guide mounting surface 3120, and the circumferential side of the terminal shell 4 is provided with a recessed guide portion 11. When the integrated pump head 3, the terminal guide body 504 and the terminal shell 4 are installed, the raised guide portion 554 on the circumferential side of the terminal guide body 504 cooperates with the recessed guide portion 11 to play a role of guiding and positioning, thereby making the installation efficiency higher.

[0072] Furthermore, the front side wall of the impeller chamber 501 extends toward the main shaft 204, and a sealing component 521 is installed on the inner edge of the front side wall. The sealing component 521 is sleeved on the outer side of the middle sleeve part 5110 of the impeller assembly 511, and a ring cover 531 is installed on the front side wall of the impeller chamber 501. A sealing component installation cavity 541 is formed between the ring cover 531 and the front side wall of the impeller chamber 501, and the sealing component 521 is arranged in the sealing component installation cavity 541; the front and rear sides of the sealing component 521 are clamped by the ring cover 531 and the impeller chamber 501; a certain spare area is provided between the outer side of the sealing component 521 and the circumferential inner wall of the sealing component installation cavity 541, and the inner side of the sealing component 521 extends out of the sealing component installation cavity 541; when the inner side of the sealing component 521 is subjected to a certain external force, it moves in the sealing component installation cavity 541, automatically adjusts the radial position, and achieves a dynamic sealing effect.

[0073] 1 and 531, and the sealing member 521 is provided with a plurality of sealing members ... During the rotation, the middle sleeve part 5110 of the impeller assembly 511 may hinder the sealing component 521. At this time, the impeller assembly 511 will push the sealing component 521 to rotate in the sealing component installation cavity 541 until there is no obstruction between the sealing component 521 and the impeller assembly 511. After that, the sealing component 521 and the middle sleeve part 5110 of the impeller assembly 511 can move relative to each other without obstruction. The advantage of this structure is that it ensures that the reserved gap between the middle sleeve part 5110 of the impeller assembly 511 and the sealing component 521 is minimized, thereby better controlling the situation where part of the water flow in the next-level impeller chamber flows back through the gap to the impeller chamber of the previous level, resulting in a decrease in the pressure at the water outlet, thereby further improving the working efficiency of the water pump; in addition, during the operation of the water pump, the sealing component 521 will not shift with the movement or vibration of the pump body 2, thereby ensuring the stability of the sealing component 521.

[0074] Furthermore, the sealing component 521 of this embodiment is preferably a ceramic ring or an engineering plastic ring, both of which have high hardness and are convenient for pushing and adjusting during the running-in period of the water pump.

[0075] Furthermore, a plastic cylinder 506 is provided on the front side wall of the impeller chamber 501, and a hole is provided on the ring cover 531. The plastic cylinder 506 passes through the corresponding hole in the ring cover 531 to form an expansion portion 516. The expansion portion 516 fixes the ring cover 531 to the front side wall of the impeller chamber 501. The expansion portion 516 is formed by heating the plastic cylinder 506 to a softened state and then pressurizing and cooling it to form a fixed shape. The expansion portion 516 has a rivet-like structure. The advantage of this design is that the ring cover 531 is tightly mounted on the front side wall of the impeller chamber 501, ensuring that the ring cover 531 will not shift or loosen, further making the ring cover 531 more stable, and thus making the structure more stable, thereby extending the service life of the water pump. The cross-sectional shape of the plastic cylinder can be circular, elliptical, or other shapes, and the corresponding hole shape can also be adjusted accordingly.

[0076] Among them, the impeller chamber 501 can be made of engineering plastic, and the plastic column 506 and the impeller chamber 501 are integrally formed, making the structure more stable; the impeller chamber 501 can also be made of metal, and it is necessary to pre-open a groove with a large internal diameter and a small external diameter at the position where the plastic column 506 is set, and then the softened plastic column 506 is directly inserted into and fills the groove. After cooling and shaping, the installation of the plastic column 506 and the fixation of the ring cover 531 are completed.

[0077] Furthermore, a reflux channel 8 is provided on one side of the water-gas separation chamber 6, and the reflux channel 8 connects the storage chamber 602 and the water inlet 502 of the guide body assembly 5. A self-priming valve 7 is provided at the outlet of the reflux channel 8, which cuts off the reflux channel 8 when the self-priming valve 7 is in a closed state and connects the reflux channel 8 when the self-priming valve 7 is in an open state; an elastic member 702 is provided on the valve stem 701 of the self-priming valve 7, and the elastic member 702 enables the self-priming valve 7 to maintain a movement tendency in an open state; an electromagnetic coil part 703 is provided at the lower part of the self-priming valve 7, and the electromagnetic coil part 703 generates magnetic force when it is turned on, which adsorbs the self-priming valve 7 to move downward and keep it in an open state.

[0078] Among them, the self-priming valve 7 includes a valve stem 701, an elastic member 702 and an electromagnetic coil part 703. The valve stem 701 is cylindrical, the elastic member 702 is a spring, a valve cover 704 is arranged around the valve stem 701, and a sealing ring 705 is arranged on the valve cover 704. The valve stem 701 is used to conduct or cut off the opening of the reflux channel 8, and the sealing ring 705 prevents water from overflowing or passing through. The valve stem 701 is located below the valve cover 704 to form a blocking part 711; the electromagnetic coil part 703 is located on the lower side of the self-priming valve 7, and a groove 713 is provided on the upper side of the electromagnetic coil part 703, and the blocking part 711 moves in the groove 713; wherein, the valve stem 701 is a metal component.

[0079] When the pump body 2 is pumping air, if the pressure in the pump body 2 meets the standard, the blocking part 711 moves upward, the valve stem 701 pushes the elastic part 702 and compresses the elastic part 702, and the valve cover 704 covers the opening of the reflux channel 8 to prevent water from flowing back. If the pressure in the pump body 2 is small and does not meet the standard, the elastic part 702 expands and pushes the valve cover 704, thereby causing the blocking part 711 to move downward, opening the reflux channel 8. When the elastic force of the elastic part 702 is less than the water pressure, the electromagnetic coil part 703 generates magnetic force and exerts a downward pulling force on the adsorbed valve stem 701, increasing the elastic force of the elastic part 702, thereby causing the valve stem 701 to move downward, opening the reflux channel 8; during this process, the blocking part 711 is always in the groove 713. The advantage of this structure is that the blocking part 711 avoids deviation during the up and down movement, thereby avoiding the situation where the reflux channel 8 cannot be normally cut off or opened.

[0080] Furthermore, the electromagnetic coil part 703 is screwed into the installation groove 306 , and the electromagnetic coil part 703 extends into the installation groove 306 from the outside of the pump body 2 , and is installed on both sides by screws and nuts.

[0081] like Figure 3 As shown, when the pump body 2 is gas-filled, the program detects the pressure change in the pump body 2 and then detects whether the inhaled water flow meets the standard. When the pressure in the pump body 2 meets the standard, the self-priming valve 7 is closed, and the valve cover 704 cuts off the reflux channel 8, and the water flow cannot flow back, reducing the energy loss of the pump body 2 and further improving the energy utilization rate of the pump body 2; when there is more gas in the water flow, the internal pressure of the pump body 2 is relatively small, the self-priming valve 7 is opened, and the blocking part 711 moves downward to conduct the reflux channel 8. The water flow accumulates in the storage chamber 602 of the water-gas separation chamber 6 and is re-delivered by the impeller assembly 511 through the reflux channel 8. At the same time, the pump inlet 101 is also inhaling water flow, and the water flow in the pump body 2 gradually increases until the pressure of the pump body 2 meets the standard, the self-priming valve 7 is closed, and the pump body 2 returns to normal working state.

[0082] Furthermore, a pump motor 205 is provided on one side of the terminal housing 4 , and a silent fan 10 is installed on one side of the pump motor 205 . The silent fan 10 is used to dissipate heat for the pump motor 205 .

[0083] The silent fan 10 includes a blade mounting portion 1001 and an air guide blade 1002. The blade mounting portion 1001 is a circular substrate, which is mounted on the main shaft 204. The air guide blades 1002 are evenly spaced and circumferentially arranged on the blade mounting portion 1001. The advantage of this structure is that it is conducive to better guiding hot air into the interior of the fan blade. There are 15 air guide blades 1002. The thickness of the air guide blades 1002 gradually shrinks from the side close to the edge of the blade mounting portion 1001 to the side close to the center of the blade mounting portion 1001, forming a gas buffer surface 10021 on the inner side. The air guide blades 1002 are arranged from the top to the bottom. The width gradually becomes smaller towards the bottom, and a first air guide portion 10022 is formed on the side away from the center of the blade mounting portion 1001, and a gas buffer cavity 10023 is formed between two adjacent air guide blades 1002. The side of the gas buffer cavity 10023 away from the center of the blade mounting portion 1001 forms an air inlet 1005, and the side of the gas buffer cavity 10023 close to the center of the blade mounting portion 1001 forms an air outlet 1006; in addition, the first air guide portion 10022 is formed on the side of the air guide blade 1002 close to the air inlet 1005, and the width of the first air guide portion 10022 gradually narrows from top to bottom, and the lower side is gathered at the edge of the blade mounting portion 1001.

[0084] Furthermore, the edge of the blade mounting portion 1001 gradually bulges toward the middle to form a second air guide surface 10010 , and the air inlet 1005 , the gas buffer cavity 10023 , the air outlet 1006 and the second air guide surface 10010 are connected to form a complete heat dissipation channel.

[0085] Furthermore, a fixing ring 1007 is provided on the outer side of the upper end of the first air guide portion 10022. The blade mounting portion 1001, the air guide blade 1002 and the fixing ring 1007 are integrally formed, which is convenient for manufacturing and saves costs. The fixing ring 1007 is used to assist in fixing the air guide blade 1002, which is beneficial to improving the shape retention of the air guide blade 1002, improving the structural stability of the air guide blade 1002, and further extending the service life of the air guide blade 1002. The diameter of the fixing ring 1007 is larger than the diameter of the blade mounting portion 1001. The tangent of the inner lower end of the air guide blade 1002 and the connection position of the blade mounting part 1001 forms an angle a with the tangent of the corresponding position of the edge of the blade mounting part 1001, and the optimal value of the angle a is 134°. The tangent of the inner upper end of the air guide blade 1002 and the connection position of the fixing ring 1007 forms an angle b with the tangent of the corresponding position of the fixing ring 1007, and the optimal value of the angle b is 165°. The angle b is greater than the angle a. The advantage of this structure is that it is conducive to the first air guide part 10022 to better contact the hot air and introduce the hot air.

[0086] Furthermore, a drive connection hole 10011 is provided at the center of the blade mounting portion 1001 for connecting to the main shaft 204 , and the drive connection hole 10011 is cylindrical.

[0087] Furthermore, a reinforcement rib installation cavity 1004 is formed on the reverse side of the second air guide surface 10010, the drive connection hole 10011 is located at the center of the reinforcement rib installation cavity 1004, and five reinforcement ribs 1003 are evenly spaced around the drive connection hole 10011. The width of the reinforcement rib 1003 gradually narrows from one end close to the drive connection hole 10011 to the end close to the edge of the reinforcement rib installation cavity 1004, so that the structure of the reinforcement rib 1003 is more stable, and thus the structure of the drive connection hole 10011 is more stable.

[0088] The external driving structure of this embodiment is a water pump motor, and this embodiment is used to dissipate heat for the water pump motor. When the water pump motor is working, it drives the fan blade to rotate. The water pump motor generates heat during operation, and the hot air is introduced into the gas buffer chamber 10023 of the fan blade through the first air guide portion 10022 of the fan blade, and the hot air is discharged outward through the second air guide surface 10010. In this process, because the area of ​​the first air guide portion 10022 gradually increases from the air inlet 1005 to the air outlet 1006 of the fan blade, and the thickness of the air guide blade 1002 increases from the air inlet 1005 to the air outlet The opening 1006 gradually contracts and forms a gas buffer surface 10021 on the inside. Therefore, when the wind contacts the wind guide blade 1002, the contact surface between the wind and the wind guide blade 1002 gradually increases, and the force area of ​​the wind on the wind guide blade 1002 gradually increases, and the impact pressure of the wind on the wind guide blade 1002 decreases due to the increase in the force area, and the friction between the wind and the wind guide blade 1002 decreases, which not only achieves the purpose of reducing the wind noise, but also reduces the damage rate of the wind guide blade 1002 and extends the service life of the wind guide blade 1002.
