Description

Technical Field

[0001] This utility model belongs to the field of fluid transport equipment technology, and in particular relates to an impact-resistant ceramic impeller with a metal frame. Background Technology

[0002] With the research on ceramic materials technology, the application fields are constantly expanding. Existing technologies mainly produce high-temperature resistant plates and small integral ceramic impellers, but there are problems such as ceramic impellers being unable to be scaled up and being not impact-resistant and prone to breakage. It is necessary to optimize the structure of ceramic impellers to solve these problems. Utility Model Content

[0003] The purpose of this invention is to solve the problems of traditional ceramic impellers, such as inability to be scaled up, poor impact resistance, and easy breakage, and to provide an impact-resistant ceramic impeller with a metal frame.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] This utility model discloses an impact-resistant ceramic impeller with a metal frame, comprising a ceramic outer frame, a metal inner frame, a ceramic rear cover plate, and a ceramic pressure block.

[0006] The ceramic outer frame has a circular plate-shaped mounting cavity on its rear end face, and each blade of the ceramic outer frame has an axially penetrating blade metal support mounting cavity.

[0007] The metal inner skeleton includes a main metal support and a blade metal support;

[0008] The middle part of the main metal support body is a metal hub that matches the front end of the pump shaft. The front end of the hub is provided with a plate-shaped metal support body. The plate-shaped metal support body has a blade metal support positioning elongated hole that matches the distribution position of the mounting cavity of the ceramic outer skeleton blade metal support body.

[0009] The main metal support and the ceramic rear cover are sequentially glued into the circular plate-shaped mounting cavity of the ceramic outer skeleton. The blade metal support is glued into the mounting cavity of each blade metal support of the ceramic outer skeleton, and the rear end of each blade metal support is inserted into the positioning elongated hole of each blade metal support of the main metal support. The ceramic pressure block is glued to the front end of the mounting cavity of each blade metal support of the ceramic outer skeleton, so that the metal inner skeleton is completely encapsulated in the ceramic outer skeleton.

[0010] Beneficial effects

[0011] This invention relates to an impact-resistant ceramic impeller, which combines a metal frame with a ceramic impeller, solving the problem in existing technologies where ceramic components are not impact-resistant and cannot be mass-produced. This impact-resistant ceramic impeller can meet the impact requirements of high-torque starting of large ceramic impellers, is safe and reliable in use, has low manufacturing difficulty, and is suitable for mass production.
