QJR hot water deep well pump prices

QJR hot water deep well pump, as the name suggests, is in the hot water environment in the use of QJ deep well submersible pump. Its structure and QJ deep well submersible pump is the same, by the pump head, motor, submersible cable composition, the difference is hot water deep well pump motor and diving cables are required to be heat-resistant. The following are the specific requirements of hot water submersible pumps:
1, hot water pump power requirements:
 (1) rated frequency of 50 Hz, the motor rated voltage should be guaranteed to 380 +5 volts of three-phase AC power (if the user voltage is 660 volts to be special orders).
 (2) Transformer load power should not exceed 75% of its capacity.
 (3) transformer far away from the well, the transmission line voltage drop should be considered for power greater than 45KW of the motor, requiring the transformer to the wellhead distance of not more than 20 meters, more than 20 meters, the requirements of transmission line specifications than with cable specifications Level and consider the line voltage drop.
2, water quality requirements:
  1: Allowable operating water temperature range: +5 to +105 ℃;
  2: solid impurity content (mass ratio) is not more than 0.01%;
  3: PH value (pH) 6.5-8.5;
  4: hydrogen sulfide content of not more than 1.5mg / L;
  5: chloride ion content of not more than 400mg / L;
  6: crew must completely invade the water work. Vertical use, select the model diameter and pump models to match, should not use large diameter diameter of small diameter pump, this is not conducive to the motor cooling.
3, wellbore requirements: integrity, smooth, no protrusion or well tube dislocation phenomenon, well diameter is not less than the corresponding frame number.
