Tubular Flow Pump

Second, technical characteristics

    The principle of the full-flow submersible electric pump device is that the pump impeller is installed in the rotor inner cavity of the motor and forms an integral part with the rotor. The rotor is equivalent to the impeller casing of the water pump, so that the invalid part of the motor becomes the working part, and the water flows from the rotor during operation. The cavity flows through, and the device maintains the advantages of investment in the submersible electric pump, compact structure, convenient installation, low noise, and good heat dissipation. Since the water flows straight in and out, the full-flow submersible electric pump has the characteristics of good hydraulic performance, smooth flow path and high device efficiency.

1. Wet stator structure, windings do not need to be sealed

    The coil of the wet stator winding structure is a special water-resistant winding wire patented by the multi-layer eutectic co-extrusion winding wire technology, which is not afraid of water immersion, and has no insulation safety problem caused by poor sealing leakage.Reliability is much higher than existing dry stator submersible pumps.

2. Compact size and shortened size

    Small in size and compact in size, the axial size is reduced by nearly half compared to conventional dry submersible axial pumps. Light weight, metal consumption savings of 40%, enabling fast self-installation. Simplified pumping station structure can be derived by a large number of installation methods suitable for engineering applications, such as vertical, horizontal and inclined. It is especially suitable for pumping stations with two-way irrigation and drainage. Horizontal cross flow is the main installation method, and it can also be installed diagonally or vertically.

3. The efficiency of the device is obviously improved

    The water flow passes through, reducing the influence of the turning and the special-shaped tube, the flow velocity distribution is uniform, the flow state is smooth, the local loss is small, and the flow path is short, the flow path loss is small, and the device efficiency is obviously improved.

4. Very low noise and good heat dissipation

    The operating conditions are greatly improved, the underwater heat dissipation conditions are good, the noise is low, and the environmental impact is small.

 5. Easy to operate and manage, easy to control automatically. The amount of foundation excavation is small and the construction period is short.
