AI Technical Summary

Technical Problem

The existing centrifugal submersible pumps have excessively long support pipes, pump shafts, and outlet pipes, resulting in high material consumption and easy vibration, which affects the stability of normal operation.

Method used

Design a submersible pump with an extended suction pipe. The pump head is set at the highest liquid level in the reservoir. The suction pipe consists of multiple detachable suction pipe units connected by lugs and screws. The surface of the suction pipe is coated with a corrosion-resistant non-metallic anti-corrosion layer. The support pipe is fixed to the pump head and pump body.

Benefits of technology

The shortening of the pump shaft and outlet pipe reduces vibration, improves operational stability, saves material consumption, and enhances the product's market competitiveness and service life.
