Full through flow submersible gate pump

Full through flow submersible gate pump

Product introduction

Full tubular submersible pump is the product of the combination of full tubular pump technology and gate technology. It is mainly used for electromechanical drainage and irrigation, water transfer between rivers, circulating water for urban environment and landscape, low lift and large flow water intake project combined with flood control and drainage or drainage and irrigation.

performance parameter

Nominal diameter 350 ~ 4000mm, lift 1 ~ 30m, flow 15-300000m3 / h, power 7.5 ~ 2000kW, voltage 380 ~ 10kV, water quality conditions, water temperature ≤ 50 ℃, pH value 4 ~ 10, the water quality is mild sewage, the equivalent diameter of particles ≤ 1 / 10, and there is no large amount of fiber sundries.

Technical features

The principle of the full through flow submersible electric pump device is that the water pump impeller is installed in the rotor cavity of the motor to form a whole with the rotor. The rotor is equivalent to the impeller shell of the water pump, so that the invalid part of the motor becomes the working part. During operation, the water flows through the rotor cavity. The device maintains the advantages of the submersible pump, such as low investment, compact structure, convenient installation, low noise and good heat dissipation. Because the water flows in and out directly, the full perfusion submersible electric pump has the characteristics of good hydraulic performance, smooth flow channel and high device efficiency.

1. With wet stator structure, the winding does not need to be sealed

The coil of wet stator winding structure is a water-resistant winding wire manufactured by using multi-layer co melting and co extrusion winding wire technology. It is not afraid of water immersion, and there is no insulation safety problem caused by poor sealing and water leakage. It is much higher than the existing dry stator submersible pump.

2. Compact structure and shortened size

Small size and compact structure. Compared with the traditional dry submersible axial flow pump, the axial size is shortened by nearly half. Light weight, saving 40% of metal consumption, and can realize rapid self coupling installation. A large number of installation methods suitable for engineering application, such as vertical, horizontal and inclined, can be derived to simplify the structure of the pump station. The pump station is suitable for the combination of two-way drainage and irrigation. Horizontal tubular is the main installation method, and it can also be installed obliquely or vertically.

3. The efficiency of the device is significantly improved

The water flows through to reduce the influence of bends and special-shaped pipes. The flow velocity distribution is uniform, the flow pattern is smooth, and the local loss is very small. In addition, the flow channel is short and the flow channel loss is small, so the efficiency of the device can be significantly improved.

4. Extremely low noise and good heat dissipation conditions

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

5. Convenient operation management and automatic control. The amount of foundation excavation is small and the construction period is short.
