AI Technical Summary

Technical Problem

When transporting highly corrosive media or media containing fine particles, the sealing mechanism of traditional centrifugal pumps directly contacts the shaft, which leads to high requirements for the performance of the shaft material, increased manufacturing and maintenance costs, and easy damage to the internal structure of the pump body when encountering large particles that cause jamming.

Method used

The system employs a power separation structure, which includes a drive motor, transmission device, fixed disc, return spring, and bearing. The return spring drives the fixed disc to engage with the drive disc. When resistance is encountered, the fixed disc locks onto the bearing, achieving power separation and preventing the drive motor from continuing to rotate, thus protecting the pump body structure.

Benefits of technology

It effectively protects the internal structure of the pump body, avoids damage caused by sudden resistance, reduces maintenance costs, and simplifies the maintenance process.
