Model Description

product structure

1. Cable: The cable adopts a watertight cable;

2. Junction box: The junction box is fully enclosed and isolated from surrounding liquids and stator boxes;

3. Motor: 50Hz squirrel cage 3-phase submersible asynchronous motor, F-class insulation, protection level IP68. The motor is cooled by the surrounding medium;

4. Shaft: The shaft of the electric motor is made of stainless steel material, and the rotor undergoes dynamic balance testing;

5. Sealing: The static seal is an O-ring seal. The shaft seal is a mechanical seal that isolates the oil chamber from the surrounding medium;

6. Bearings: The bearings used have a designed service life of over 100000 hours;

7. Oil chamber: Oil is used to lubricate and cool the mechanical seal friction pair, and isolate the permeate;

8. Impeller: The impeller has three blades, which are wide and thin, with a smooth and swept back surface, efficient and unobstructed operation, and have self-cleaning function;

9. Cone tube: The purpose of a cone tube is to form a better flow state;

10. Discharge joint: The discharge joint is used to fix the cone tube on the outlet pipe;

11. Guidance device: The guidance device consists of two pipes (conduits) and an upper conduit clamp.
