Small submersible pump voltage is too low

Small submersible pump is widely used in our daily life, the following voltage is too low, the small submersible pump how to use the correct, Zhengzhou Nine Dragons pump technical staff will give you a reasonable proposal:
As the power supply voltage is too low cause a small submersible pump can not start, the need to adjust the power supply voltage to 342V or more. In the disaster emergency drainage must use a small submersible pump, if the voltage is lower than 342v, you can take temporary and measures: appropriate to adjust the large pump protection switch setting current, so that the use of small submersible pump, the protection switch will not Frequent tripping due to overload. But should be used to control the submersible pump stator winding current does not exceed 1.1 times its rated current, and control the use of time, so that small submersible pump will not be used for too long, overload too long, resulting in stator winding temperature rise too high overheating damage.
