Description

Technical Field

[0001] The present invention relates to the technical field of fluid delivery, and in particular to a multi-cavity booster pump. Background Art

[0002] As an important device used to do work on fluid during fluid transportation, booster pumps are widely used in existing industrial production and human life.

[0003] When supplying water, the existing booster pump is affected by the structure inside the booster pump, so that the pumping efficiency of the booster pump is low. Summary of the invention

[0004] The object of the present invention is to provide a multi-cavity booster pump, which improves the water pumping efficiency of the booster pump by adding a plurality of cavities.

[0005] In order to solve the above technical problems, the present invention adopts the following solutions:

[0006] A multi-chamber booster pump comprises a pump head body and a pump cover. A connecting seat for connecting a motor is connected to the pump head body. A source water chamber, a water outlet chamber and a booster chamber are arranged in the pump head body. The connecting seat is connected to the pump head body to form an installation chamber. A compression assembly is matched and installed in the installation chamber. The compression assembly changes the volume of the booster chamber through a booster diaphragm. The source water chamber and the water outlet chamber are respectively connected to the water inlet and the water outlet on the end cover assembly. The booster chamber is connected to the water outlet chamber and the source water chamber. The transverse axis of the pump head body has two or more through chambers circumferentially distributed and located in the pump head body. The water outlet chamber is formed at the intersection of multiple through chambers. A one-way assembly is arranged in the through chamber to control the connection or blocking of the water path between the source water chamber and the booster chamber, and the water path between the booster chamber and the water outlet chamber. The pump cover, the booster diaphragm and the pump head body are sealed together to form a booster chamber.

[0007] Compared with the prior art, the existing booster pump has fewer pumping cavities. The source water is sucked into the boosting cavity by the action of the motor, and then pumped out to the outside from the water outlet. Its pumping capacity is limited. In the present technical solution, two or more through cavities are arranged in the circumference of the transverse axis of the pump head body. The through cavity is connected with the source water cavity, the boosting cavity, and the water outlet cavity. A one-way component is matched and installed in each through cavity. The one-way component only allows water to flow from the source water cavity to the boosting cavity and from the boosting cavity to the water outlet cavity. The volume of the boosting cavity is changed by driving the compression component by the motor. When the volume of the boosting cavity increases, the water in the source water cavity is sucked into the boosting cavity through the one-way component and the related waterway; when the volume of the boosting cavity decreases, the water inside the boosting cavity is pressed into the water outlet cavity at the convergence of each through cavity through each one-way component, and then flows out through the water outlet. Under the drive of the compression component driven by the motor, the boosting cavity opens and closes in such a cycle, and water is sucked and discharged through the one-way components in multiple through cavities at the same time, thereby improving the pumping efficiency of the booster pump. The booster pump structural design in this solution optimizes the internal water channel structure of the entire booster pump.

The side wall of the eccentric piece is sleeved with a bearing, and the bearing is connected to the connecting sleeve. The boost diaphragm is located in the boost chamber and is circumferentially compressed and sealed between the pump cover and the pump head body. A matching pressure piece is provided in the middle of the boost diaphragm. The screw passes through the pressure piece, the boost diaphragm, and the connecting rod sleeve from top to bottom to compress and fix the boost diaphragm between the pressure piece and the connecting rod sleeve. A sleeve for supporting the boost diaphragm is sleeved on the connecting rod sleeve.

[0010] Preferably, a first sealing ring and a second sealing ring are provided between the end cover assembly and the pump head body, and the first sealing ring and the second sealing ring are pressed into the groove formed by the pump head body through the end cover assembly to strengthen the sealing performance between the end cover assembly and the pump head body and prevent water from the source water cavity and the outlet water cavity from leaking out of the installation gap.

[0022] Example 1

[0023] A multi-chamber booster pump, including a pump head body 37 and a pump cover 13. The pump head body 37 is connected to a connection seat 15 for connecting a motor. The pump head body 37 is provided with a source water chamber 05, a water outlet chamber 27, and a booster chamber 08. The connection seat 15 is connected to the pump head body 37 to form an installation chamber 14. A compression assembly is matched and installed in the installation chamber 14. The compression assembly changes the volume of the booster chamber 08 through a booster diaphragm 11. The source water chamber 05 and the water outlet chamber 27 are respectively connected to the water inlet 01 and the water outlet 03 on the end cover assembly 02. The booster chamber 08 is connected to the water outlet chamber 27 and the source water chamber 05. The transverse axis of the pump head body 37 is circumferentially distributed with two or more through chambers 36 located in the pump head body 37. The transverse axis is relative to Figure 1 The structure in FIG. 1 is described as follows. The transverse axis and the center line of the water outlet cavity 27 are in a straight line. The circumferential direction of the transverse axis can be understood as a plurality of through cavities 36 distributed in the circumferential direction of the water outlet cavity 27. Figure 2 As shown, with the water outlet chamber 27 as the center, a plurality of through chambers 36 are provided in the radial direction thereof, and the water outlet chamber 27 is formed at the intersection of the plurality of through chambers 36. A one-way component 07 is provided in the through chamber 36 for controlling the connection or blocking of the water path between the source water chamber 05 and the boosting chamber 08, and the water path between the boosting chamber 08 and the water outlet chamber 27. The pump cover 13, the boosting diaphragm 11, and the pump head body 37 are jointly sealed to form the boosting chamber 08.

[0024] In this embodiment, Figure 1 and 2As shown, two or more through cavities 36 are arranged in the circumferential direction of the transverse axis of the pump head body 37, and the through cavities 36 are simultaneously connected to the source water cavity 05, the boosting cavity 08, and the water outlet cavity 27. A one-way component 07 is matched and installed in each through cavity 36, and the one-way component 07 only allows water to flow from the source water cavity 05 to the boosting cavity 08, and the boosting cavity 08 to the water outlet cavity 27. The volume of the boosting cavity 08 is changed by driving the compression component by a motor. When the volume of the boosting cavity 08 located above increases, the water in the source water cavity 05 is sucked into the boosting cavity 08 through the one-way component 07 and the related water path. At this time, the volume of the boosting cavity 08 located below becomes smaller, and the water inside the boosting cavity 08 is pressed into the water outlet cavity 27 at the convergence of each through cavity 36 through each one-way component 07, and then flows out through the water outlet 03; and vice versa. Driven by the motor driving the compression assembly, the boost chamber 08 opens and closes in a reciprocating cycle, and at the same time, water is absorbed and discharged through the one-way assembly 07 in the multiple through cavities 36, thereby improving the pumping efficiency of the boost pump. The boost pump structural design in this solution optimizes the internal waterway structure of the entire boost pump.

[0025] Example 2

[0026] Specifically, the one-way component 07 includes an inlet baffle 20, a support frame 29, a water outlet baffle 33, an inlet one-way diaphragm 22, and an outlet one-way diaphragm 31. The inlet baffle 20 is matched with the inlet one-way diaphragm 22, and the outlet baffle 20 is matched with the outlet one-way diaphragm 31. The support frame 29 is respectively connected with the outlet baffle 33 and the inlet baffle 20 to form the one-way component 07, and the one-way component 07 is tightly connected with the inner wall of the through cavity 36. A water inlet passage cavity 38 is formed between the inlet one-way diaphragm 22 and the support frame 29, and a water outlet passage cavity 30 is formed between the outlet one-way diaphragm 31 and the support frame 29. The periphery of the inlet baffle 20 is pressed and sealed between the pump cover 13 and the pump head body 37. The inlet baffle 20 and the support frame 29 are respectively provided with The first flow channel 21 and the second flow channel 24 are connected to the water inlet passage chamber 38, and a water inlet groove 35 formed by the pump cover 13 body is provided on the top of the support frame 29. The water inlet groove 35 is connected to the boosting chamber 08. The second flow channel 24 is connected to the source water chamber 05 through the source water through hole 25 formed by the pump head body 37. The water inlet one-way diaphragm 22 is located on the water path between the first flow channel 21 and the water inlet groove 35. A water inlet nozzle 23 connected to the water inlet groove 35 is provided on the top of the support frame 29. A water outlet flow channel connecting the water inlet nozzle 23 and the water outlet passage chamber 30 is provided in the support frame 29 body. A third flow channel 32 connecting the water outlet chamber 27 and the water outlet passage chamber 30 is provided on the water outlet baffle 33. The water outlet one-way diaphragm 31 is located on the water path between the third flow channel 32 and the water outlet chamber 27.

[0027] The specific working principle of this embodiment is as follows: when the motor is not working, the source water in the source water chamber 05 enters the water inlet and water passage chamber 38 through the source water through hole 25 and the second flow channel 24 for temporary storage. When the motor is working, the motor drives the compression assembly to change the volume of the boost chamber 08, so that the volume of the boost chamber 08 increases or decreases. When the volume of the boost chamber 08 increases, suction is generated in the boost chamber 08, so that the water inlet one-way diaphragm 22 opens, and the water in the water inlet and water passage chamber 38 enters the water inlet groove 35 and the boost chamber 08 through the second flow channel 24 and the water inlet one-way diaphragm 22. In the pressure chamber 08; when the volume of the boosting chamber 08 is reduced by compression, the water in the boosting chamber 08 is compressed and can only enter the water outlet chamber 30 through the water inlet nozzle 23 and the water outlet channel, and is further pressed into the water outlet chamber 27 through the third channel 32 and the water outlet one-way diaphragm 31. The boosting chamber 08 reciprocates in a cycle of opening and closing, and starts to take in water after the water is discharged, thereby ensuring the continuity of the water outlet; through the setting of multiple through cavities 36 and the internal one-way component 07, the amount of water inlet and outlet is increased, thereby improving the water pumping efficiency of the boosting pump. The reasonable design of multiple through cavities 36 optimizes the internal water channel structure of the booster pump, making the structure more reasonable. The water inlet one-way diaphragm 22 can effectively prevent water from flowing back from the water inlet groove 35 to the source water chamber 05, so that when the boosting chamber 05 presses water, the water will not be pressed out from the water inlet one-way diaphragm 22. The water outlet one-way diaphragm 31 can effectively prevent the water in the water outlet chamber 27 from flowing back to the water outlet passage chamber 30. When the boosting chamber 08 absorbs water, it can prevent the water in the water outlet chamber 27 from being sucked back into the water outlet passage chamber 30.

[0028] Example 3

[0029] Specifically, the compression assembly includes a boost diaphragm 11, a screw 10, a connecting rod sleeve 16, and an eccentric piece 19. The eccentric piece 19 is provided with an eccentric hole 18 connected to the output end of the motor. The side wall of the eccentric piece 19 is sleeved with a bearing 17, and the bearing 17 is connected to the connecting sleeve 16. The boost diaphragm 11 is located in the boost chamber 08 and is circumferentially compressed and sealed between the pump cover 13 and the pump head body 37. A matching pressure piece 09 is provided in the middle of the boost diaphragm 11. The screw 10 passes through the pressure piece 09, the boost diaphragm 11, and the connecting rod sleeve 16 from top to bottom to compress and fix the boost diaphragm 11 between the pressure piece 09 and the connecting rod sleeve 16. The connecting rod sleeve 16 is sleeved with a sleeve 12 for supporting the boost diaphragm 11.

[0030] like Figure 1As shown, the working principle of the compression assembly in this embodiment is as follows: the output end of the motor is connected to the eccentric hole 18 of the eccentric piece 09, the motor drives the eccentric piece 09 to rotate, the eccentric piece 09 drives the external bearing 17 to make an eccentric movement, the eccentric movement of the bearing 17 drives the connecting rod sleeve 16 to follow the eccentric movement, because the screw 10 fixes the boost diaphragm 11 and the connecting rod sleeve 16 as a whole, and at the same time the middle of the boost diaphragm 11 is pressed by the pressing piece 09, and the sheath 12 supports the bottom of the boost diaphragm 11 The boosting diaphragm 11 is circumferentially compressed and sealed between the pump cover 13 and the pump head body 37, and the eccentric movement of the connecting rod sleeve 16 causes the connecting rod sleeve 16 to move up and down. When the connecting rod sleeve 16 moves upward, the volume of the upper boosting chamber 08 decreases, and the volume of the lower boosting chamber 08 increases. Conversely, when the connecting rod sleeve 16 moves downward, the volume of the upper boosting chamber 08 increases, and the volume of the lower boosting chamber 08 decreases, thereby realizing the change of the volume of the boosting chamber 08, and then realizing the suction and discharge of water.

[0031] Example 4

[0032] Specifically, a first sealing ring 26 and a second sealing ring 04 are provided between the end cover assembly 02 and the pump head body 37, and the first sealing ring 26 and the second sealing ring 04 are pressed into the groove formed by the pump head body 37 through the end cover assembly 02. The sealing performance between the end cover assembly 02 and the pump head body 37 is strengthened to prevent water from leaking from the source water cavity 05 and the water outlet cavity 27 from the installation gap.

[0033] Specifically, a sealing gasket 06 is provided at the connection between the pump cover 13 and the pump head body 37, and the sealing gasket 06 is pressed into the installation groove formed by the pump head body 37 through the pump cover 13. The sealing performance of the entire booster pump device is enhanced to ensure that water in the internal cavities and flow channels will not leak out from the installation gap between the pump cover 13 and the pump head body 37.

[0034] Specifically, the water inlet baffle 20 is provided with a sealing groove in the circumference, and a third sealing ring 28 is sleeved in the sealing groove to strengthen the sealing performance between the one-way component 07 and the inner wall of the through cavity 36, so as to prevent the water in the source water cavity 05 from leaking into the water outlet cavity in advance through the installation gap between the one-way component 07 and the inner wall of the through cavity 36, thereby affecting the normal working performance of the booster pump.

[0035] Specifically, the outlet baffle plate 33 is provided with a sealing groove in the circumference, and a fourth sealing ring 34 is sleeved in the sealing groove to strengthen the sealing performance between the one-way component 07 and the inner wall of the through cavity 36, so as to prevent the water in the source water cavity 05 from leaking into the outlet cavity in advance through the installation gap between the one-way component 07 and the inner wall of the through cavity 36, thereby affecting the normal working performance of the booster pump.
