Description

Technical Field

[0001] This utility model relates to water pumps, and in particular, to a high-efficiency and energy-saving split-type pipeline booster pump. Background Technology

[0002] A booster pump is a type of pump used in pipelines to increase the pressure of fluids within the pipeline. It is widely used in domestic water supply, industrial circulation systems, and water supply for high-rise buildings.

[0003] Currently, Chinese patent CN217873310U discloses a booster pump, including a pump body, a drive motor connected to the pump body, the drive motor including a motor housing and a shielding sleeve, the motor housing being fixedly connected to the pump body, the shielding sleeve being located inside the motor housing, the shielding sleeve having a first mounting hole, the first mounting hole being coaxially fixed to a fixed shaft, the pump body having an inlet chamber, an impeller chamber and an outlet chamber, the inlet chamber and the outlet chamber being connected through the impeller chamber.

[0004] The aforementioned patent still has shortcomings. When the booster pump is used in the industrial field, the pump body and motor are integrated, which requires complete disassembly for maintenance. In addition, the head is low and the power consumption is high when supplying high-pressure water. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a high-efficiency and energy-saving split-type pipeline booster pump, which solves the problems mentioned in the background.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a high-efficiency and energy-saving split-type pipeline booster pump, including a motor body and a water pump body. The water pump body includes a housing, a central rod and multiple impellers connected in series. The housing is provided with an inlet and an outlet. The central rod and impellers are disposed inside the housing. The impellers are arranged in a straight line and fixed on the central rod. The impellers deliver the medium from the inlet to the outlet. The output shaft of the motor body is detachably connected to the central rod.

[0007] Preferably, a coupling is provided between the output shaft of the motor body and the central rod, and a mounting platform is provided at the upper end of the housing, and the motor body is fixed to the mounting platform by screws.

[0008] Preferably, the housing includes a base, a sleeve, and an upper mounting base. The water inlet and outlet are disposed on the base, the sleeve is disposed between the base and the upper mounting base, and a fixing rod is disposed around the upper mounting base. The fixing rod passes through the base and is locked by a nut.

[0009] Preferably, a flow channel is formed between the casing and the outer side of the impeller. The medium enters the impeller from the inlet and flows into the flow channel, and then flows from the flow channel to the outlet. A sealing ring is provided between the casing, the base, and the upper mounting seat. The fixing rod cooperates with the nut to press the casing tightly against the sealing ring.

[0010] Preferably, the base is further provided with a bearing seat, the bearing seat is provided with a self-lubricating bearing, the central rod is fixed to the inner ring of the self-lubricating bearing, and the bearing seat is fixed to the outer ring of the self-lubricating bearing.

[0011] Preferably, the pump body is further provided with a one-way component, which includes a sliding sleeve, a one-way valve plate, and a pressure seat. The sliding sleeve is fixed on the central rod, and the one-way valve plate is slidably disposed on the sliding sleeve. The one-way valve plate has a first inclined top surface on its outer side, and the pressure seat has a second inclined top surface. When the medium enters the pump body, the one-way valve plate slides upward and separates the first inclined top surface from the second inclined top surface. When the booster pump is turned off, the one-way valve plate moves downward by gravity and abuts the first inclined top surface from the second inclined top surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By adopting a split design for the motor body and the water pump body, and with the output shaft of the motor body being detachably connected to the central rod, the installation, disassembly and maintenance of the equipment are facilitated, reducing maintenance costs and time. Through multiple series impellers forming a multi-stage pressurization structure on the central rod, the head performance is significantly improved, enabling stable operation under high-pressure water supply conditions, while reducing energy consumption per unit flow. 2. The housing adopts a split structure of base, shell sleeve and upper mounting seat, with locking method of fixing rod and nut, which not only facilitates the processing and manufacturing of each part of the housing, but also facilitates the inspection and replacement of internal components. The setting of sealing ring effectively prevents medium leakage and ensures the normal operation of booster pump; 3. The self-lubricating bearing installed in the base reduces the frictional resistance when the central rod rotates, lowers energy consumption, extends the service life of the equipment, and the self-lubricating characteristic also reduces the dependence on lubricants during maintenance.

[0013] 4. The design of the unidirectional component prevents backflow of the medium when the booster pump is shut down, avoiding the impact and damage to the equipment caused by water hammer due to backflow, and improving the reliability and stability of the equipment. Attached Figure Description

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0017] A high-efficiency, energy-saving, split-type pipeline booster pump includes a motor body 1 and a pump body 2. The pump body 2 includes a housing 3, a central rod 4, and multiple impellers 5 connected in series. The housing 3 has an inlet 6 and an outlet 7. The central rod 4 and impellers 5 are housed inside the housing 3, with the impellers 5 arranged in a straight line and fixed to the central rod 4. The impellers 5 deliver the medium from the inlet 6 to the outlet 7. The output shaft of the motor body 1 is detachably connected to the central rod 4. A coupling 8 is also provided between the output shaft of the motor body 1 and the central rod 4. A mounting platform 9 is also provided at the upper end of the housing 3, and the motor body 1 is fixed to the mounting platform 9 with screws. Because the motor body 1 and the pump body 2 are designed as separate units, and the output shaft of the motor body 1 is detachably connected to the central rod 4, the installation, disassembly, and maintenance of the equipment are facilitated. When the equipment needs to be repaired, only the motor body 1 and the pump body 2 need to be separated, and the internal components of the pump body 2 can be repaired and replaced, greatly reducing maintenance costs and time.

[0018] The housing 3 includes a base 10, a sleeve 11, and an upper mounting base 12. An inlet 6 and an outlet 7 are located on the base 10. The sleeve 11 is positioned between the base 10 and the upper mounting base 12. A fixing rod 13 is arranged around the upper mounting base 12, passing through the base 10 and locked by a nut. A flow channel 14 is formed between the sleeve 11 and the outer side of the impeller 5. The medium enters the impeller 5 from the inlet 6 and flows into the flow channel 14, then flows from the flow channel 14 to the outlet 7. A sealing ring 15 is provided between the sleeve 11 and the base 10 and the upper mounting base 12. The fixing rod 13 cooperates with the nut to press the sleeve 11 tightly against the sealing ring 15.

[0019] The split structure of housing 3, combined with the locking mechanism of the fixing rod 13 and nut, not only facilitates the manufacturing of each part of housing 3 but also makes the inspection and replacement of internal components easier. During maintenance, simply loosening the fixing rod 13 and nut allows the housing 11 to be removed from between the base 10 and the upper mounting seat 12, enabling the inspection and replacement of internal components. This design improves the maintainability of the equipment and extends its service life.

[0020] The base 10 also contains a bearing housing 16, within which a self-lubricating bearing 17 is installed. The center rod 4 is fixed to the inner ring of the self-lubricating bearing 17, and the bearing housing 16 is fixed to the outer ring of the self-lubricating bearing 17, thereby reducing the frictional resistance when the center rod 4 rotates. The self-lubricating bearing 17 does not require additional lubricating oil, avoiding the problem of oil contamination of the medium, making it particularly suitable for water supply systems with high water quality requirements.

[0021] The pump body 2 is also equipped with a one-way component 18, which includes a sliding sleeve 19, a one-way valve plate 20, and a pressure seat 21. The sliding sleeve 19 is fixed on the central rod 4, and the one-way valve plate 20 is slidably mounted on the sliding sleeve 19. The outer side of the one-way valve plate 20 is provided with a first inclined top surface 22, and the pressure seat 21 is provided with a second inclined top surface 23. When the medium enters the pump body 2, the one-way valve plate 20 slides upward and separates the first inclined top surface 22 from the second inclined top surface 23. When the booster pump is turned off, the one-way valve plate 20 moves downward by gravity and abuts the first inclined top surface 22 against the second inclined top surface 23.

[0022] The process is as follows: When the booster pump is turned on, the medium enters the pump body 2. The check valve plate 20 slides upwards under the pressure of the medium, separating the first inclined surface 22 from the second inclined surface 23, allowing the medium to pass smoothly. When the booster pump is turned off, the check valve plate 20 moves downwards under gravity and water pressure, causing the first inclined surface 22 to abut against the second inclined surface 23, thus preventing backflow of the medium. This design avoids the impact and damage to the equipment caused by water hammer due to backflow, improving the reliability and stability of the equipment.

[0023] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
