250QJB Profundus Bene Submersible Pump

The product adopts special waterproof wire design, which can realize long-term stable conversion operation of the motor within the frequency range of 1HZ-50HZ. The frequency conversion winding design not only makes the frequency conversion deep well pump more energy saving, but also prolongs its service life. The motor winding adopts special water-resistant conductors that are resistant to high frequency impact, pulse peak voltage impact and high temperature aging, with excellent characteristics and stability.

The product is powered by three-phase AC 380V power supply, 50HZ frequency, suitable for the environment with harsh water quality conditions. Specific requirements include water temperature below 20 °C, solid impurities content is not greater than 0.01%, PH value is 6.5-8.5, hydrogen sulfide content is not greater than 1.5mg/L, chloride ion content is not greater than 400mg/L. The product adopts closed or water immersion structure of the motor, before use to ensure that the pump is fully filled with water, no-load test run is strictly prohibited. The pump must be completely immersed in water, not more than 70m water depth, water source to meet the requirements of the pump water output and continuous operation. In addition, the well must be vertical, the pump can only be used vertically. The wiring should be supported according to the requirements, and equipped with external overload protection device. This series of requirements to ensure the efficient and stable operation of the product, suitable for all kinds of special environment of the pump demand.

1, well submersible pump for clean water pump, prohibit the new well, pumping sediment and muddy water,

2, well water pump voltage grade of 380/50HZ, the use of other voltage grades of submersible motors need to be customized. The underground cable must use waterproof cable, must be equipped with starting equipment, such as distribution box, start not ready should have commonly used motor comprehensive protection function, such as short circuit overload protection, phase protection, undervoltage protection, grounding protection, idling protection, in case of abnormal conditions, the protection device should be timely action trip.

3, the installation and use of the pump must be reliably grounded, prohibit the push and pull switch when the hands and feet are wet, the installation and maintenance of the pump must be cut off the power supply, the use of the pump place to set up "to prevent electric shock" obvious signs:

4, down the well or before installation, the motor cavity must be filled with distilled water or non-corrosive clean cold boiling water, tighten the / water bolt, the pump on the ground test run, must be to the pump chamber water lubrication rubber bearings, instant start not more than a second, see whether the steering is the same as the steering instructions. When the pump is upright, pay attention to safety, prevent overturning injury.

V, stricte secundum praescripta sentinae tollunt, fluunt usui, ne humilis fluat vel alta vi flare tollat, impulsus sustinens et alias partes indumenti, motor oneris combustus.

6, after the pump down the well, the measurement of the motor to the ground insulation resistance should not be less than 100M, after the start to observe the voltage and current, check the motor winding insulation, whether in line with the requirements; pump storage location temperature if less than freezing point, should be dry the motor cavity water, prevent the motor cavity water ice damage caused by low temperature.

The pump parts are mainly composed of pump shaft, impeller, shunt shell, rubber bearing, check valve body and so on; the motor part mainly includes base, pressure regulating diaphragm, thrust bearing, thrust plate, lower guide bearing seat, stator, rotor, upper guide bearing seat, sand discharging ring, water inlet section, cable lead, etc. The main characteristic of the product is that the motor is a water-filled wet submersible three-phase asynchronous motor, the motor cavity is filled with water, used to cool the motor and lubricate the bearing; the pressure regulating diaphragm at the bottom is used to adjust the expansion and contraction pressure difference of the internal water caused by the change of the temperature rise of the motor. In order to prevent the sand particles in the well water from entering the motor, two sand sealing rings are installed on the upper end of the motor shaft extension, and a sand discharging ring is installed to form a sand prevention structure. To prevent the pump shaft from jumping when starting up, the pump shaft is connected with the motor shaft through a coupling, and the thrust bearing is installed on the lower part of the motor. The motor and pump bearing adopt water lubrication technology, and the stator winding of the motor adopts high quality submersible motor winding with high insulation performance. The pump is designed by computer CAD, with simple structure and excellent technical performance.
