The technical solution for the suspended semi submersible vertical turbine pump impeller

The technical solution for the suspended semi submersible vertical turbine pump impeller is as follows: a suspended semi submersible vertical turbine pump impeller is provided with a steel disc, five upper blade steel skeletons, and five lower blade steel skeletons. The five upper blade steel skeletons and five lower blade steel skeletons are respectively connected to the steel disc by welding, forming the entire impeller steel skeleton; Set the steel wheel disc wear-resistant rubber pad as the first rubber pad, the five upper blade steel skeleton wear-resistant rubber pads as the second rubber pad, and the five lower blade steel skeleton rubber pads as the third rubber pad. The steel wheel disc, five upper blade steel skeleton, five lower blade steel skeleton, and rubber pads are cast as a whole on the entire impeller steel skeleton by high-temperature heating. The beneficial effects of this technical method are good wear resistance, long service life, and improved conveying capacity of the conveying pump.

Technical requirements: 1. A suspended semi submersible vertical turbine pump impeller, characterized in that: a steel disc (1), five upper blade steel skeletons (2), and five lower blade steel skeletons (3) are set, and the five upper blade steel skeletons (2) and five lower blade steel skeletons (3) are respectively connected to the steel disc (1) by welding to form the entire impeller steel skeleton; Set the steel wheel disc (1) with wear-resistant rubber pad (6) as the first rubber pad, five upper blade steel frames (2) with wear-resistant rubber pad (5) as the second rubber pad, and five lower blade steel frames (3) with rubber pad (4) as the third rubber pad. The steel wheel disc (1), five upper blade steel frames (2), five lower blade steel frames (3), and rubber pad are cast as a whole on the entire impeller steel frame by high-temperature heating.
