AI Technical Summary

Technical Problem

In aluminum liquid booster pumps, the metal transition parts expand at high temperatures, causing them to grow larger. This increases the clearance between parts and the risk of loosening, affecting the stability and safety of the equipment.

Method used

A fan and air distribution duct are installed on the drive unit of the aluminum liquid lifting pump. The impeller joint is cooled by blowing air through the air supply duct to reduce the temperature of the metal parts. The air supply duct with a steel wire hose lining is easy to move and avoid obstacles.

Benefits of technology

It effectively reduces the temperature of the impeller joint and output shaft joint, avoids thermal deformation and loosening, ensures stable and safe operation of the equipment, and reduces material and construction costs.

Abstract

This utility model belongs to the technical field of aluminum liquid vortex well systems, and discloses a cooling mechanism for the impeller connector of an aluminum liquid pump. It is installed on the drive unit of an aluminum liquid booster pump. An impeller is vertically arranged below the drive unit. The mechanism includes a fan, an air supply pipe, and an air distribution pipe. The fan is mounted on the top plate of the drive unit base frame, and its outlet is connected to the air distribution pipe via the air supply pipe. The air distribution pipe is vertically arranged below the base frame and blows air to cool the impeller connector at the top of the impeller. This aluminum liquid pump impeller connector cooling mechanism can cool the pump impeller connector by blowing air, reducing the working temperature of the metal transition parts and ensuring stable and safe operation of the equipment.
