Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting molds, in particular to a casting mold for a zirconium corundum water pump volute. Background Art
[0002] Zirconia corundum is a composite material composed of zirconium oxide (ZrO2) and aluminum oxide (Al2O3). Due to zirconium oxide's high strength, wear resistance, and high-temperature stability, zirconium corundum is often used to manufacture high-temperature and wear-resistant components, such as industrial refractories and cutting tools. Zirconia corundum's properties make it well-suited for use in harsh environments, such as high temperatures and corrosive media.
[0003] The volute of the water pump is a key component in the centrifugal pump. The volute is shaped like a snail shell. Its main function is to guide the liquid discharged by the water pump impeller to the outlet through a spiral channel, and convert part of the kinetic energy into pressure energy to improve the efficiency of the pump.
[0004] Casting molds: Casting molds are used to manufacture parts. Liquid material (such as metal or plastic) is injected into the mold cavity, and the material cools and solidifies to form a specific shape. For zirconium corundum, the design and manufacture of casting molds must take into account its high melting point and unique physical and chemical properties.
[0005] In practice, water pump volutes are typically demolded using steel shot blasting. However, this approach presents significant challenges. While effective in releasing the pump volute from the mold, this process can also cause significant surface damage. Tiny particles or abrasion can lead to grain damage or uneven quality on the volute surface, significantly impacting not only its visual appearance but also its fire resistance and service life. This damage can increase frictional losses during operation, reducing efficiency and potentially leading to more serious mechanical failures over time. Utility Model Content
