Easy. Generator refers to a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other electrical machine. It converts energy generated by water flow, air flow, fuel combustion or atomic energy. nuclear fission into mechanical energy and transmits it to the generator. It is then converted into electrical energy by the generator. The community generator is easily damaged if used continuously for a day. Generally, the usage time cannot exceed 12 hours. Exceeding 12 hours can easily cause device overheating, mechanical fatigue and device damage.
Please use with caution.
The main component of the submersible pump is the motor. Starting the motor has the particularity of requiring a significant starting current, qui is about 3 to 7 times the rated current. Calculated, a 1.5 kW motor requires at least a 7-8 kW generator to start. Therefore, higher power motors must be equipped with a star angle conversion device or a variable frequency starting device. Particularly for heavy-start loads (all submerged in water) such as submersible pumps, starting will instantly cause the overcurrent protection to trip.
There is a way to check this. Before starting the submersible pump, lift it out of the water, then close it and start the submersible pump without load, after the motor runs normally, turn it on slowly. in water. The main objective of using this method is to avoid starting under heavy load. If it can continue to work, it means the motor has high quality and good performance; if it goes offhe always due to overload you can only switch to a high power generator.
