Description

Technical Field

[0001] This utility model relates to the field of water pump technology, and in particular to a high-pressure sealed water pump. Background Technology

[0002] Currently, large-scale water pumps often require a dedicated sealing pump to ensure reliable sealing water operation during operation. Previously, this was conventionally achieved by connecting a water pipe from the main pump. However, the frequent pressure fluctuations of the main pump resulted in inconsistent sealing water supply, necessitating a dedicated pump to meet this requirement. In response, this pump unit was developed specifically for ensuring the sealing water supply of high-pressure and supercritical water pumps.

[0003] However, high-pressure sealed water pump units are often fixed to a rigid base with bolts. This installation method is not only inefficient, but also requires specialized tools. This makes it time-consuming and labor-intensive to disassemble, repair and maintain the water pump later, which is not conducive to improving the convenience of disassembly, maintenance and repair and the efficiency of disassembly and assembly work. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a high-pressure sealed water pump.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-pressure sealed water pump, including a rigid base, a pump body disposed on the surface of the rigid base, a motor fixedly connected to the top of the pump body, an inlet end and an outlet end disposed on the surface of the pump body, a mounting base fixedly connected to the bottom of the pump body, a locking block fixedly connected to the surface of the mounting base, the locking block engaging with the rigid base, a locking groove being formed on the surface of the rigid base, a bidirectional lead screw being laterally rotatably connected inside the locking block, an L-shaped locking plate one and an L-shaped locking plate two being threadedly connected to the surface of the bidirectional lead screw, the L-shaped locking plate one and the L-shaped locking plate two being engaged inside the locking groove, and a knob fixedly connected to one end of the bidirectional lead screw.

[0006] Preferably, there are two sets of L-shaped clamping plates, which are symmetrically distributed on both sides of the middle of the surface of the mounting base. There are also two sets of L-shaped clamping plates, which are symmetrically distributed on both sides of the middle of the surface of the mounting base.

[0007] Preferably, the surface of the knob is fixedly connected with anti-slip ribs, which are evenly distributed on the surface of the knob.

[0008] Preferably, a flow divider is provided inside the water inlet, and the edge of the flow divider is fixedly connected to the inner wall of the water inlet.

[0009] Preferably, both the inlet and outlet are fixedly connected to flanges, and the surface of the flanges is provided with fixing holes.

[0010] Preferably, the flange surface has a sealing groove, and a metal sealing gasket is provided inside the sealing groove.

[0011] Preferably, the water pump is mounted on a rigid base in a column-like manner.

[0012] Preferably, the surface of the rigid base is provided with a limiting groove, and the bottom of the mounting base is fixedly connected with a limiting rod. The limiting rods are distributed at the four corners of the mounting base and are inserted into the limiting groove.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by using a locking block to engage with the rigid base slot and fixing it with a two-way screw rod, L-shaped locking plate one, and L-shaped locking plate two, compared with the traditional method of fixing only with bolts, the installation does not require complicated bolt tightening operations or too many professional tools, which greatly improves the installation efficiency and allows the water pump to be installed on the rigid base more quickly and put into use. At the same time, when disassembling, inspecting, and maintaining, simply rotating the knob to drive the two-way screw rod can easily release the fixing relationship between the locking plate and the slot, making it easy to remove the pump body from the rigid base. This effectively improves the convenience and efficiency of disassembly and assembly work and reduces maintenance costs and time costs.

[0015] 2. In this utility model, a limiting groove is opened on the surface of the rigid base, and a limiting rod is fixedly connected to the four corners of the bottom of the mounting base and inserted into the limiting groove. This design can accurately position the water pump during the installation process, ensuring that the water pump is installed in the correct position and avoiding installation deviation. At the same time, during the operation of the water pump, the displacement of the water pump is further restricted, enhancing the stability of the water pump installation and ensuring that the water pump can still operate stably and reliably under the conditions of water flow impact and vibration. It can also protect the L-shaped clamping plate one and the L-shaped clamping plate two. Attached Figure Description

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 - Figure 5As shown, this utility model provides a technical solution: a high-pressure sealed water pump, including a rigid base 1, a pump body 3 on the surface of the rigid base 1, a motor 4 fixedly connected to the top of the pump body 3, the motor 4 being a Class I energy-efficient pump using a high-quality rigid coupling to significantly reduce power consumption and improve overall efficiency, an inlet end 5 and an outlet end 6 on the surface of the pump body 3, a mounting base 2 fixedly connected to the bottom of the pump body 3, a locking block 12 fixedly connected to the surface of the mounting base 2, the locking block 12 engaging with the rigid base 1, a slot 18 on the surface of the rigid base 1, a bidirectional lead screw 13 laterally rotatably connected inside the locking block 12, and an L-shaped locking plate 14 and an L-shaped locking plate 15 threadedly connected to the surface of the bidirectional lead screw 13. Plate 14 and L-shaped clamping plate 15 are clamped inside the clamping groove 18. One end of the bidirectional screw 13 is fixedly connected to a knob 16. There are two sets of L-shaped clamping plates 14, which are symmetrically distributed on both sides of the middle of the surface of the mounting base 2. There are two sets of L-shaped clamping plates 15, which are symmetrically distributed on both sides of the middle of the surface of the mounting base 2. Anti-slip ribs 17 are fixedly connected to the surface of the knob 16 and are evenly distributed on the surface of the knob 16. A diversion baffle 7 is provided inside the water inlet 5. The edge of the diversion baffle 7 is fixedly connected to the inner wall of the water inlet 5. Flanges 8 are fixedly connected to both the water inlet 5 and the water outlet 6. Fixing holes 10 are opened on the surface of the flanges 8.

[0026] In this embodiment, by using a locking block 12 to engage with the slot 18 of the rigid base 1, and fixing it with a bidirectional screw rod 13, L-shaped locking plate one, and L-shaped locking plate two, compared to the traditional method of fixing only with bolts, installation does not require complicated bolt tightening operations or too many professional tools, greatly improving installation efficiency. This allows the water pump to be installed on the rigid base 1 and put into use more quickly. Furthermore, during disassembly, inspection, and maintenance, simply rotating the knob 16 to rotate the bidirectional screw rod 13 easily releases the locking plate from the slot 18, facilitating the removal of the pump body 3 from the rigid base 1. This effectively improves the convenience and efficiency of disassembly and assembly, reducing maintenance and time costs. The two sets of L-shaped locking plates one and two sets of L-shaped locking plates two further enhance the efficiency of the pump installation. The second type of clamping plate is symmetrically distributed on both sides of the center of the mounting base 2, which makes the force on the water pump more even when it is fixed to the rigid base 1. This ensures the stability of the water pump after installation and avoids tilting or shaking caused by uneven force. This, in turn, ensures the smooth operation of the water pump, extends the service life of the water pump and related components, and reduces the potential for failure due to unstable installation. The knob 16 has anti-slip ribs 17 evenly distributed on its surface, which increases the friction between the operator's hand and the knob 16 when rotating it. To prevent hand slippage and ensure more precise and smooth operation, the knob 16 can be easily turned even in adverse operating environments such as dampness or oil stains, further improving the convenience and reliability of the entire installation and disassembly process. With flanges 8 fixedly connected to both the inlet end 5 and the outlet end 6, and fixing holes 10 on the flanges 8, the water pump is easily connected to external pipes. Using bolts and other connecting parts in conjunction with the fixing holes 10, the inlet and outlet pipes can be quickly and securely connected to the water pump, ensuring the sealing and reliability of the pipe connection.

[0027] Example 2: As Figure 3 - Figure 5 As shown, a sealing groove 9 is provided on the surface of the flange 8, and a metal sealing gasket 11 is provided inside the sealing groove 9. The water pump is mounted on a rigid base 1 in a column-like manner. A limit groove 19 is provided on the surface of the rigid base 1. A limit rod 20 is fixedly connected to the bottom of the mounting base 2. The limit rod 20 is distributed at the four corners of the mounting base 2 and is inserted into the limit groove 19.

[0028] In this embodiment, a sealing groove 9 is opened on the surface of the flange 8 and a metal sealing gasket 11 is built in. When connected to an external pipeline, it can effectively fill the tiny gaps at the connection point, forming a reliable sealing structure. This prevents water leakage and seepage during the operation of the water pump, ensuring the water pump's sealing performance and improving the operational stability of the entire water supply system. It also avoids water waste and adverse environmental impacts caused by leakage. The water pump adopts a vertical structure, reducing the floor space and greatly minimizing the volume and space occupied by the entire sealing unit. A limiting groove 19 is opened on the surface of the rigid base 1, and limiting rods 20 are fixedly connected to the four corners of the bottom of the mounting base 2 and inserted into the limiting groove 19. This design can accurately position the water pump during installation, ensuring that the water pump is installed in the correct position and avoiding installation deviations. At the same time, it further restricts the displacement of the water pump during operation, enhances the stability of the water pump installation, and ensures that the water pump can still operate stably and reliably under conditions such as water flow impact and vibration. It can also protect the L-shaped clamping plate one and L-shaped clamping plate two.

[0029] The working principle of this embodiment is as follows: During use, when installing the high-pressure sealing water pump, the limiting rod 20 at the bottom of the mounting base 2 of the high-pressure sealing water pump is aligned with the limiting groove 19 on the surface of the rigid base 1 and inserted to achieve initial positioning, so that the high-pressure sealing water pump can be accurately placed in the predetermined position. Then, the locking block 12 on the mounting base 2 is engaged with the locking groove 18 of the rigid base 1. By rotating the knob 16, the bidirectional lead screw 13 is driven to rotate. The surface of the knob 16 is evenly distributed with anti-slip ribs 17, which increases the friction between the operator's hand and the knob 16 when the operator rotates the knob 16, preventing the hand from slipping. Since the bidirectional lead screw 13 is threadedly connected to L-shaped locking plates one and two, as the lead screw rotates, L-shaped locking plates one and two... The second type of clamping plate moves laterally inside the clamping block 12 and finally locks into the clamping groove 18, completing the stable installation of the high-pressure sealing water pump on the rigid base 1. This installation method is simple to operate and reliable. Regarding the connection between the high-pressure sealing water pump and external pipelines, the flanges 8 at the inlet end 5 and the outlet end 6 play a crucial role. Through the fixing holes 10 on the flanges 8, bolts and other connecting parts are used to connect to the external inlet and outlet pipes. The sealing groove 9 on the flanges 8 and the internal metal sealing gasket 11 ensure the sealing of the connection points, preventing water leakage. Simultaneously, the high-pressure sealing water pump is installed as a column on the rigid base 1, reducing the floor space and significantly minimizing the overall volume of the sealing unit. This ensures that the high-pressure sealing water pump continuously and stably provides sealing water for equipment requiring sealing water, such as high-pressure and supercritical high-pressure sealing water pumps, meeting the sealing requirements under special operating conditions. Furthermore, it integrates with the main unit and the DCS of the main system. To ensure the reliability and efficiency of the entire operation, linkage and other control measures are implemented. During operation, water enters the pump body from the inlet 5. The diversion baffle 7 inside the inlet 5 diverts the incoming water flow, ensuring a uniform and stable flow towards the impeller inlet. This prevents vortices, surges, and other undesirable flow conditions, guaranteeing the stability of the incoming water. After entering the impeller, the blades at the impeller inlet have a rounded and appropriately enlarged curvature design, and the blade outlet cross-section is trimmed to improve the high-pressure sealing performance. (Pump hydraulic performance), the motor 4 drives the impeller to rotate at high speed. Based on the principle of centrifugal force, the impeller does work on the water flow, increasing the kinetic energy and static pressure energy of the water flow, and raising the pressure. Then, it is transported to the outlet end 6 through the flow channel inside the pump body 3. This high-pressure sealed water pump meets the needs of special working conditions in the industry, meets the applicability of high-pressure and supercritical water pumps for sealing water under special needs, meets the reliability guarantee of withstanding high pressure and frequent pressure changes, and has low cost, small space occupation, strong economy, convenient installation, and convenient piping, throttling and start-up control.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
