The working principle of the invention is that the water pump body 1 works to convey liquid, wherein the conveying is that the rotation of the impeller assembly 4 generates driving force, if the water contains impurities such as stones, sand, silt and the like, the impurities can enter the water pump body 1 along with water flow and directly impact the impeller assembly 4, so that the surface of the impeller assembly 4 is damaged, worn and deformed, and cavitation corrosion is possibly even generated, and cavitation corrosion damage is formed. Such damage not only reduces the working efficiency of the impeller, but also may affect the overall performance and the service life of the water pump body 1, wherein the damage to the impeller assembly 4 is difficult to completely avoid, and the accumulated water is more likely to remain in the damaged impeller assembly 4, and the surface area of the impeller assembly 4 is increased, so that the damage is difficult to avoid rust even if the protective layer is coated, and therefore, the maintenance is required after the completion.
In the maintenance process, by moving the rust prevention unit 5, the arc-shaped groove 55 clamps the sector plate 43, so that impurities adhered to the sector plate 43 can be scraped off in the moving process, the sector plate 43 is completely exposed, the corrosion to the sector plate 43 is reduced, and the driving effect of the water pump body 1 is also avoided.
Simultaneously, the end cover 54 is opened, lubricating oil is infused from the inside of the end cover 54, so that the lubricating oil moves to the inside of the cavity layer 51 along the first liquid outlet 57 and moves to the inner slit 56, contact with the sector plate 43 is realized, the lubricating oil is coated on the sector plate 43, air can be isolated, the sector plate 43 is corroded as much as possible, in addition, the lubricating oil can be contacted with the sector plate 43 after impurities on the sector plate 43 are scraped, the consumption of the lubricating oil moving from the inner slit 56 can be reduced as much as possible, and waste is reduced.
The connecting pipe 53 can be driven to move through the water inlet 44, so that the water pump body 1 is prevented from being disassembled, and looseness among parts is avoided.
In the running process of the impeller assembly 4, the inner slit 56 and the first liquid outlet 57 in the arc-shaped groove 55 are blocked by the sector plate 43, so that the influence of liquid transmission is avoided, even if the influence is caused, the liquid is only entered into the cavity layer 51, impurities are not entered, the second liquid outlet 591 on the outer side is easy to enter the impurities, then the baffle circle 593 is arranged to block the second liquid outlet 591 under the action of the supporting spring 595, in addition, the driving port 599 is inserted through a screwdriver, the supporting rod 597 can be rotated, the pull rope 596 is pulled, the baffle circle 593 is separated from the protruding layer 592, the second liquid outlet 591 is opened, lubricating oil can be thrown out along the second liquid outlet 591 when the sector plate 43 rotates, the inside of the pump body 3 is coated, the thrown lubricating oil can be relatively dispersed, the pump body 3 is coated to the greatest extent, the consumption of the lubricating oil is reduced, and the water pump body 1 is prevented from being detached.
