Description

Technical Field

[0001] This utility model belongs to the field of axial flow pump technology, specifically a chemical axial flow pump that is easy to maintain. Background Technology

[0002] In chemical production, chemical axial flow pumps are a common type of pump, which work by relying on the lift generated by the impeller rotation on the water flow.

[0003] Chemical axial flow pumps are based on the lift theory of airfoils in aerodynamics. When the impeller rotates, the blades, similar to airfoils, create a pressure difference between the upper and lower surfaces of the fluid. The pressure on the lower surface is less than that on the upper surface, which generates an upward reaction force on the fluid, propelling the fluid to flow axially.

[0004] After prolonged use, chemical axial flow pumps require maintenance and repair. The complex structure of chemical axial flow pumps, with numerous fasteners assembling various parts, makes maintenance difficult. Therefore, this paper proposes a chemical axial flow pump that facilitates maintenance. Utility Model Content

The lower end of the coupling 5 is located inside the outlet bend 2. A shaft 7 is installed at the lower end of the coupling 5. A quick-release mechanism is installed at the lower end of the shaft 7. The quick-release mechanism allows the user to quickly remove the guide vane impeller 8 from the lower end of the shaft 7 for easy maintenance.

[0033] The quick-release mechanism is equipped with a guide vane impeller 8, which is used to pump the chemical liquid in the pump body 1 into the outlet bend 2.

[0034] Furthermore, such as Figure 1 and Figure 2 As shown, the pump casing connection mechanism includes a lower connecting flange 9 on the pump body 1 and an upper connecting flange 10 below the outlet bend 2. The lower connecting flange 9 has an annular groove 11, and the upper connecting flange 10 has a retaining ring 12. The retaining ring 12 and the annular groove 11 engage with each other. The lower connecting flange 9 and the upper connecting flange 10 are connected by screws.
