QJR is specially designed for geothermal applications featured by heat-resisting, anti-corrosion and anti-aging properties, water temperature up to 90℃
Construction & Features
- Compact vertical centrifugal multi-stage design with perfect standardization and generalization, easy operation and convenient maintenance.
- A complete electric submersible pump includes a water pump set, electric motor, a discharge piping, water-proof cable and a control panel.
- Submersible motor filled with clean water for cooling and lubrication. And the pressure regulation switch, located at the bottom of motor, shall automatically operate to
- balance the pressure fluctuation caused by temperature variations.
- A sand slinger and oil-sealed skeleton are equipped at the upper part of motor to form a closed operating system for the motor, thus preventing any sand to penetrate into the motor.
- Water injection hole, as well as air release hole, are designed at the upper part of the motor, and water release hole at bottom (lower) part.
- Thrust bearing and collar are designed at lower part of motor to stand the weight of the squirrel caged rotor and the axial thrust residual.
- Water-proof electromagnetic wiring for stator with excellent insulation.
