Structural characteristics of deep shaft submersible PUMPS May 08, 2017

1. impeller for centrifugal closed structure, and through the static balance test, sealing ring material for HT200.

2. Water pump shaft adopts (30CR13) or 45 steel to adjust the treatment, the surface of hard chromium plating.

3. Bearings: Should meet the continuous operation of 12 months without fault.

4. After the submersible pump assembly, should rotate evenly, no card lag phenomenon.

5. The pump inlet area is closed with the net, the filter net over water is not less than the impeller inlet area of 5 times times.

6. The pump body is subjected to hydraulic pressure test, the test pressure is 1.5 times times the pressure of the work, the holding pressure 5 minutes does not allow leakage.
