Description

Technical Field

[0001] This utility model belongs to the field of delivery pumps, specifically relating to an energy-saving, stable-flow, high-pressure delivery pump. Background Technology

[0002] In modern industrial systems, high-pressure transfer pumps are key equipment for ensuring the efficient flow of various liquid media. Their applications are widely covered in many fields such as industrial production, municipal water supply, and agricultural irrigation, making them the "heart" of liquid transport systems. In the field of industrial production, whether it is the precise transport of chemical raw materials, the supply of cooling circulating water in the metallurgical industry, or the high-pressure transmission of boiler feedwater in the power system, there are stringent requirements for the operational stability of high-pressure transfer pumps.

[0003] However, during the liquid transportation process, high-pressure transfer pumps often experience increased wear on internal components due to impurities, particles, and other foreign objects in the transported medium. This not only shortens the maintenance cycle and service life of the equipment but may also cause unstable flow and increased energy consumption due to blockage by impurities. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, where high-pressure transfer pumps suffer from increased component wear and shortened maintenance cycles and service life due to impurities in the liquid transport medium, thereby realizing an energy-saving and stable-flow high-pressure transfer pump.

[0005] To achieve the above-mentioned objectives, the technical solution of this utility model is: an energy-saving, stable-flow, high-pressure delivery pump, comprising a delivery pump body and a drive motor, wherein one end of the delivery pump body is connected to a water outlet pipe; The end of the water outlet pipe away from the main body of the delivery pump is connected to a filter pipe via a flange, and a filter mechanism is snapped into the inside of the filter pipe.

[0006] In the aforementioned energy-saving, stable-flow, high-pressure delivery pump, an inlet pipe is connected to the top of the pump body.

[0007] In the aforementioned energy-saving, stable-flow, high-pressure delivery pump, the output end of the drive motor is connected to a coupling, the end of the coupling away from the drive motor is connected to a bearing housing, and the end of the bearing housing away from the coupling is connected to a drive shaft.

[0008] In the above-mentioned energy-saving and high-pressure conveying pump, a first limiting sleeve is fixed inside one side of the conveying pump body, and a second limiting sleeve is fixed on the outer surface of the same side of the conveying pump body. The drive shaft passes through the first limiting sleeve and the second limiting sleeve in sequence, and extends into the interior of the conveying pump body.

[0009] In the aforementioned energy-saving, constant-flow, high-pressure delivery pump, the filtration mechanism includes a support cover, a filter cover, and a flow divider cone; One end of the support cover is fixed with a limiting ring, and a placement groove is provided at the flange connection between the filter pipe and the water outlet pipe. The limiting ring is adapted to the placement groove. The sidewall of the support cover is provided with multiple water outlet holes, and the filter cover is snapped into the inside of the support cover.

[0010] In the aforementioned energy-saving, constant-flow, high-pressure delivery pump, the flow divider cone is fixed to the inner bottom wall of the filter cover, and the flow divider cone has a hollow structure.

[0011] In the above-mentioned energy-saving and high-pressure conveying pump, three connecting plates are evenly distributed and fixed at the bottom of the support cover, and baffles are connected between the three connecting plates; The baffle abuts against the bottom of the filter cover.

[0012] Compared with the prior art, the energy-saving, steady-flow, high-pressure delivery pump of this utility model has at least the following beneficial effects: 1. By setting up a filtration mechanism consisting of a support cover, a filter cover, and a flow divider cone, the liquid, after being filtered by the filter cover, will impact the hollow flow divider cone. The flow divider cone can disperse the liquid, making the liquid more evenly discharged from the inner wall of the filter cover, which helps to alleviate the problem of local high pressure impact caused by uneven liquid distribution in traditional single filter structure. 2. The three connecting plates at the bottom of the support cover cooperate with the baffle to form a stable support for the inner bottom wall of the filter cover, effectively reducing the pressure on the bottom of the filter cover, reducing the risk of the filter cover deforming due to long-term pressure, and further ensuring the filtration effect; 3. The first and second limiting sleeves installed on one side of the pump body provide a double limiting function for the drive shaft, which helps to reduce radial runout of the drive shaft during high-speed operation, reduce mechanical wear and noise, protect the internal components of the pump body, and extend the overall service life of the equipment.

Detailed Implementation

[0015] The energy-saving, stable-flow, high-pressure delivery pump of this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] This embodiment discloses an energy-saving, steady-flow high-pressure transfer pump. High-pressure transfer pumps suffer from drawbacks in liquid transfer, such as accelerated wear of components due to impurities in the medium, leading to shortened maintenance cycles and service life. Referring to… Figures 1-9 It mainly includes a pump body 1 and a drive motor 5. One end of the pump body 1 is connected to a water outlet pipe 3. The end of the water outlet pipe 3 away from the pump body 1 is connected to a filter pipe 4 through a flange. A filter mechanism 9 is snapped into the inside of the filter pipe 4.

[0018] The axis of the drive motor 5 is coaxial with the pump shaft of the main body of the delivery pump 1; the outlet pipe 3 is connected to the outlet end of the main body of the delivery pump 1 by a threaded seal, and its end away from the main body of the delivery pump 1 is connected to the filter pipe 4 by a flange to form a detachable connection. An annular sealing gasket is provided at the flange connection to ensure the sealing reliability under high pressure conditions; the filter mechanism 9 inside the filter pipe 4 adopts a modular design. Its snap-fit ​​structure forms a positioning fit between the annular groove on the inner wall of the filter pipe 4 and the elastic protrusion on the outer edge of the filter mechanism 9, which not only ensures the installation accuracy of the filter mechanism 9, but also facilitates quick disassembly and replacement; the inlet end face of the filter mechanism 9 and the inlet of the filter pipe 4 form a flow channel transition to avoid local pressure changes caused by liquid impact, thereby optimizing the kinetic energy distribution of the fluid during the filtration process.

[0019] Reference Figures 1-9 The top of the pump body 1 is connected to an inlet pipe 2. The output end of the drive motor 5 is connected to a coupling 6. The end of the coupling 6 away from the drive motor 5 is connected to a bearing housing 7. The end of the bearing housing 7 away from the coupling 6 is connected to a drive shaft 8.

[0020] A first limiting sleeve 10 is fixed inside one side of the pump body 1, and a second limiting sleeve 11 is fixed on the outer surface of the same side of the pump body 1; the drive shaft 8 passes through the first limiting sleeve 10 and the second limiting sleeve 11 in sequence and extends into the interior of the pump body 1.

[0021] A flow guide and rectifier is installed at the inlet end of the water inlet pipe 2 to optimize the flow field distribution when the liquid enters the pump chamber and reduce energy loss caused by eddies. The output shaft of the drive motor 5 is flexibly connected to the bearing housing 7 via a coupling 6. This coupling 6 uses a stainless steel diaphragm assembly to transmit torque, which can compensate for the axial / radial displacement between the drive motor 5 and the bearing housing 7, and avoid vibration transmission caused by rigid connection, thereby reducing system noise and energy loss. The bearing housing 7 integrates a double-row tapered roller bearing, whose preload is adjusted by the bearing end cover to ensure that the drive shaft 8 maintains a low-friction operating state under high-speed rotation. The bearing lubrication adopts a combination of oil bath lubrication and labyrinth seal. This effectively extends the service life of the bearings and reduces the frequency of maintenance. The drive shaft 8 passes through the first limiting sleeve 10 and the second limiting sleeve 11 in sequence. The first limiting sleeve 10 is embedded in the inner wall of the pump cavity of the pump body 1 and is made of copper alloy to reduce friction with the drive shaft 8. The second limiting sleeve 11 is fixed to the outer wall of the pump body 1 by bolts. Together, they form an axial-radial double constraint structure, which effectively suppresses the vibration and offset of the drive shaft 8 under high pressure conditions, ensures stable impeller rotation, and thus achieves stable flow output. In addition, the dynamic balance accuracy of the drive shaft 8 reaches G2.5, which further reduces the unbalanced force of the rotating parts and improves the smoothness of pump operation and energy efficiency ratio.

[0022] Reference Figures 1-9The filtration mechanism 9 includes a support cover 901, a filter cover 903, and a flow divider cone 906. A limiting ring 902 is fixed to one end of the support cover 901. A placement groove 401 is provided at the flange connection between the filter pipe 4 and the outlet pipe 3, and the limiting ring 902 is adapted to the placement groove 401. Multiple outlet holes are evenly distributed on the side wall of the support cover 901, and the filter cover 903 is snapped into the interior of the support cover 901. The flow divider cone 906 is fixed to the inner bottom wall of the filter cover 903, and the flow divider cone 906 has a hollow structure. Three connecting plates 905 are evenly distributed and fixed to the bottom of the support cover 901, and a baffle 904 is connected between the three connecting plates 905; the baffle 904 abuts against the bottom of the filter cover 903.

[0023] The support cover 901 of the filter mechanism 9 adopts a ring frame structure. The limiting ring 902 at its water inlet end is a ring boss, which forms an axial positioning fit with the ring placement groove 401 opened on the inner wall of the filter tube 4. Multiple water outlet holes are evenly distributed on the side wall of the support cover 901. The filter cover 903 is detachably connected to the inner wall of the support cover 901, and its mesh density is set according to the filtration accuracy requirements. The flow divider cone 906 adopts a streamlined cone structure, in which the cavity is connected to the inner cavity of the filter cover 903. After the liquid is dispersed on the surface of the flow divider cone 906, a uniform flow field is formed, reducing the direct impact on the bottom of the filter cover 903. The three connecting plates 905 at the bottom of the support cover 901 are distributed in an equilateral triangle. The baffle 904 is fixed between the connecting plates 905 by welding. Its upper surface forms a surface contact support with the bottom of the filter cover 903, effectively dispersing the local pressure generated by the liquid impact and preventing the filter cover 903 from deforming or breaking due to long-term stress.

[0024] The working principle of this utility model of energy-saving steady flow high-pressure delivery pump is as follows: First, the support cover 901 is placed inside the filter tube 4, and the limiting ring 902 on the support cover 901 is engaged in the placement groove 401. Then, the filter tube 4 is connected to the outlet pipe 3 flange. The delivery pump body 1 is started, and the delivery pump body 1 is driven to rotate through the coupling 6, bearing box 7 and drive shaft 8, drawing liquid from the inlet pipe 2 into the outlet pipe 3. After being filtered by the filter cover 903, the liquid impacts the diverting cone 906, which disperses the liquid, making the liquid more evenly discharged on the inner wall of the filter cover 903. The baffle 904 and connecting plate 905 can support the inner bottom wall of the filter cover 903, reducing the pressure on the bottom of the filter cover 903.
