Description

Technical Field

[0001] This utility model belongs to the field of centrifugal pump technology, and specifically relates to a centrifugal pump that is easy to maintain. Background Technology

[0002] Centrifugal pumps work by using the rotation of an impeller to cause water to move in a centrifugal motion. Before starting the pump, the pump casing and suction pipe must be filled with water. Then, the motor is started, and the pump shaft drives the impeller and water to rotate at high speed. The water moves in a centrifugal motion and is thrown towards the outer edge of the impeller. It then flows into the pump's discharge pipe through the flow channel of the volute casing.

[0003] In existing centrifugal pump installations, the pump is usually directly bolted to a concrete floor. When the pump is working, it needs to be connected to external pipelines. During the connection process, insufficient connection distance is common, requiring the centrifugal pump to be removed from the concrete floor and reinstalled, or the pipeline to be lengthened and spliced. This operation is cumbersome and complex, causing many inconveniences for users. In addition, existing centrifugal pumps have filters installed at their outlets to filter the pumped water. However, these filters can become clogged over time. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 - Figure 5 As shown, this embodiment provides a centrifugal pump that is easy to maintain, including a device body 1. The device body 1 contains a motor 2 and a centrifugal pump 4. A fixing plate 6 is connected below the centrifugal pump 4. A coupling 3 is provided between the centrifugal pump 4 and the motor 2. The centrifugal pump 4 is provided with an inlet 5 and an outlet pipe 7. The upper end of the outlet pipe 7 is connected to a mounting plate 8. A placement groove 10 is opened in the mounting plate 8. A placement ring 11 is installed in the placement groove 10. A filter screen 13 and a bolt 15 are installed in the placement ring 11. A support plate 16 is connected below the fixing plate 6. A base 17 is provided below the support plate 16. An installation groove 20 is opened in the base 17. A lead screw 21 is installed in the installation groove 20. A collar 23 is fitted on the lead screw 21 and one end of the lead screw 21 is connected to a motor 22. The part of the pump body that comes into contact with water is made of enamel material to achieve corrosion protection.

[0025] Preferably, both the placement ring 11 and the water outlet pipe 7 are provided with screw holes 14, and multiple sets of screw holes 14 are provided. Bolts 15 are screwed into the screw holes 14. By setting the bolts 15, the placement ring 11 and the water outlet pipe 7 can be connected and fixed, which increases the closeness and connection between the devices and ensures the safety of the devices during use. The mounting plate 8 is provided with a threaded groove 12, and a filter screen 13 is screwed into the threaded groove 12. The filter screen 13 is movably installed in the water outlet pipe 7, which can install and fix the filter screen 13, making it convenient for users to disassemble and maintain it later. A guide groove 19 is provided below the support plate 16, and a guide plate 18 is installed above the base 17. The guide plate 18 is slidably installed in the guide groove 19. By setting the guide plate 18 and the guide groove 19, the direction of movement of the device can be guided, avoiding the device from deviating in position during movement.

[0026] Preferably, mounting buckles 24 are installed on the outer wall of the base 17. Multiple sets of mounting buckles 24 are provided. By setting the mounting buckles 24, it is easy for users to install and fix the base 17, ensuring the safety of the base 17 during use. Fixing holes 9 are provided in the mounting plate 8. Multiple sets of fixing holes 9 are provided. The mounting plate 8 is fixedly connected to the water outlet pipe 7. By setting the fixing holes 9, it is easy for users to connect and fix the mounting plate 8 to external parts, providing convenience for users.

[0027] The working principle and process of this utility model are as follows: When in use, move the device to the work location and operate the centrifugal pump 4. When the operator needs to inspect or replace the filter screen 13 inside the centrifugal pump 4, disassemble the pipe connected to the mounting plate 8 of the outlet pipe 7. Using tools, unscrew the bolts 15 located in the outlet pipe 7 and the placement ring 11 in sequence. After removing the bolts 15, the user pulls the placement ring 11 upwards. As the placement ring 11 moves upwards, it moves the filter screen 13 out of the outlet pipe 7 until the filter screen 13 is completely removed. At this point, the user rotates the filter screen 13 by hand, and the filter screen 13 is rotated out from the threaded groove 12 of the placement ring 11. Then, the removed filter screen 13 can be cleaned or replaced. Conversely, the filter screen 13 can be cleaned or replaced. The installation allows for the installation and fixation of the filter screen 13 inside the device, facilitating disassembly and maintenance by the user and reducing the problem of filter screen 13 clogging and inconvenience in maintenance. When the spacing needs to be adjusted during use, the control motor 22 runs, driving the lead screw 21 to rotate in the mounting slot 20. When the lead screw 21 rotates, it drives the collar 23 to move on the lead screw 21. When the collar 23 moves, it drives the support plate 16 connected to it to move. When the support plate 16 moves, it drives the centrifugal pump 4 and the motor 2 to move accordingly until the device is adjusted to a suitable position. This allows for horizontal movement adjustment of the device, making it convenient for the user to connect and fix the device, increasing the practicality and convenience of the device, and avoiding the problem of repeated disassembly and assembly of the equipment due to insufficient installation distance.
