Hot water submersible pump starting mode

Hot water submersible pump starting mode
Diving motor and hot water submersible pump generally have four ways to start:
 1, direct start mode
For low-power submersible motors and hot water submersible pumps, generally use a direct start mode. Because the submersible motor power is small, starting electric power is not large, the power supply grid or transformer will not cause a large current impact, so do not shape the normal work of other electrical equipment.
  2, since the lotus step down starting mode
  When the submersible motor and hot water submersible pump power is relatively large, the starting current is relatively large.For the power grid or change
The device will cause a relatively large current impact, the voltage will be a greater decline, which will affect the normal operation of other electrical equipment, then, submersible motor or submersible pump should be used to start the buck.
  When the submersible motor or submersible pump leads to only one cable, that is, if the submersible motor or submersible
When the pump has only three or four leads, it should be started with self-damper.
  3, Y- △ start mode
  When the submersible motor and submersible pump power is relatively large, need to use Ah - △ start way to start the buck,
Submersible motor or submersible pump outlet cable should have two, that is, the diving motor and submersible pump should have six lead-out, can be connected into the Ya-shaped and △-shaped two different ways to start.
  4, the frequency device soft start mode
  The use of frequency conversion device to achieve soft start mode, you can eliminate the starting motor when the impact of current, thereby extending the submersible motor and submersible pump life.
