[0002] The filter mechanism of a booster pump is a component or system installed at the inlet of the booster pump to filter and purify the fluid before it is pressurized. Its main purpose is to prevent solid particles, impurities, and foreign matter in the fluid from entering the pump, thereby protecting the internal parts of the pump from wear, extending the service life of the pump, and ensuring the normal operation of the fluid system. The design and selection of the filter mechanism depends on the type of fluid, the required filtration accuracy, the operating conditions of the pump, and the overall requirements of the system. Proper selection and maintenance of the filter mechanism is crucial to ensuring the efficient and reliable operation of the booster pump.

[0003] In the existing technology, during long-term operation, the moving parts of the equipment may wear out due to lack of lubrication. A mechanism that can automatically lubricate during operation is needed to extend the life of the equipment. Therefore, the existing needs are not met. We propose a filtering mechanism for a booster pump. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: This example aims to solve the problem in the prior art that during long-term operation, the moving parts of the equipment may wear out due to lack of lubrication, and a mechanism that can automatically lubricate during operation is needed to extend the life of the equipment. Figure 1-Figure 4 A filtering mechanism of a booster pump includes a fixed block 110, a fixed cylinder 120 is fixedly installed on the side of the fixed block 110, a support rod 130 is installed on the side of the fixed block 110, a mounting shell 140 is installed on the side of the fixed cylinder 120, an extrusion groove 170 is opened in the middle of the fixed cylinder 120, a limiting rod 150 is inserted in the middle of the extrusion groove 170, an extrusion plate 160 is fixedly connected to the side of the limiting rod 150, a filter plate 180 is clamped and connected to the side of the mounting shell 140 through a clamping assembly 380, and a lubrication assembly 370 is provided in the middle of the fixed cylinder 120.

[0023] The locking assembly 380 includes a mounting slot 190 opened in the middle of the mounting shell 140, a fixing rod 200 is fixedly installed in the middle of the mounting slot 190, a push plate 290 is sleeved on the side of the fixing rod 200, and a connecting spring 210 is fixedly connected to the side of the push plate 290, and the connecting spring 210 is fixedly connected to the mounting shell 140.

[0024] When the boost pump is not started, the filter mechanism is in a stationary state, the filter plate 180 is fixed to the side of the mounting shell 140 by the locking assembly 380, the extrusion plate 160 and the limiting rod 150 are located in the extrusion groove 170, and when the boost pump is started, the fluid begins to flow and generates pressure, the fluid passes through the filter plate 180, impurities are intercepted, and the clean fluid continues to flow. As the fluid pressure increases, the push plate 290 pushes the block 270 under the action of the connecting spring 210, and the block 270 is engaged with the slot 260 on the side of the filter plate 180 to ensure that the filter plate 180 will not shift due to pressure. The limiting rod 150 and the extrusion plate 160 are subjected to the fluid pressure in the extrusion groove 170, and the extrusion plate 160 applies uniform pressure to the filter plate 180 to maintain the filtering effect.

[0025] If the fluid pressure changes, the connecting spring 210 will automatically adjust the position of the push plate 290 and the block 270 to keep the filter plate 180 stable. The design of the rotating shaft 220 and the mounting ring 230 allows the filter plate 180 to be fine-tuned when necessary to adapt to different working conditions. During the operation of the filtering mechanism, the oil absorption plate 340 on the side of the extrusion spring 330 is in intermittent contact with the extrusion plate 160 through the wiping plate 360 under the contact of the oil droplets 350 to achieve lubrication. The oil groove 300, oil rod 310, connecting plate 320 and extrusion spring 330 in the lubrication assembly 370 work together to ensure that moving parts such as the extrusion plate 160 and the limit rod 150 are continuously lubricated to reduce wear.

[0026] In this embodiment: through the arrangement of the fixing block 110, the fixing cylinder 120, the support rod 130 and the mounting shell 140, a solid structural foundation is provided, ensuring the stability of the filtering mechanism during operation; the filter plate 180 is fixed to the side of the mounting shell 140 through the snap assembly 380, which can effectively filter impurities in the fluid and protect the booster pump and other system components; through the arrangement of the snap assembly 380, the installation and replacement of the filter plate 180 becomes simple, reducing maintenance time and cost; through the arrangement of the extrusion groove 170, the limiting rod 150 and the extrusion plate 160, uniform pressure can be applied to the filter plate 180 to maintain its position while preventing displacement caused by changes in fluid pressure.

[0027] Example 2: This example is intended to solve the problem that the existing filter mechanism may be complex in design and difficult to install, maintain and replace. This example is an improvement made on the basis of Example 1. For details, please refer to Figure 1-Figure 4 A clamping block 270 is fixedly installed on the side of the push plate 290, a fixing column 280 is fixedly installed in the middle of the clamping block 270, and a clamping slot 260 is opened on the side of the filter plate 180.

[0028] The card slot 260 is engaged with the card block 270, the fixed column 280 is inserted in the middle of the rotating plate 250, the side of the mounting shell 140 is fixedly installed with the rotating shaft 220, the side of the rotating shaft 220 is installed with the mounting ring 230, one side of the mounting ring 230 is fixedly connected to the rotating plate 250, and the other side of the mounting ring 230 is fixedly connected to the pull rod 240.

[0029] The lubrication assembly 370 includes an oil groove 300 opened in the middle of the fixed cylinder 120, and an oil rod 310 is fixedly connected to the side of the oil groove 300, and a connecting plate 320 is sleeved on the side of the oil rod 310, and an extrusion spring 330 is fixedly connected to the side of the connecting plate 320, and an oil suction plate 340 is fixedly connected to the side of the extrusion spring 330, and an oil bead 350 is contacted and connected to the side of the oil suction plate 340, and a wiping plate 360 is connected to the side of the oil bead 350, and the wiping plate 360 is intermittently in contact with the extrusion plate 160.

[0030] In this embodiment: by setting the connecting spring 210, the push plate 290 and the block 270 can automatically adjust their positions when the filter plate 180 is subjected to fluid pressure, maintain the filtering effect, and reset after the pressure disappears. The setting of the block 270, the fixing column 280, the card slot 260 and the rotating plate 250 provides a reliable fixing and connection method, ensuring the stability of the filter plate 180 in high-speed fluid. The setting of the rotating shaft 220 and the mounting ring 230 increases the flexibility of the filtering mechanism, so that the filter plate 180 can adjust its angle or position as needed.
