110KW, the reactive power required when starting is about 500KVAR, the 200KVA generator can provide about 200*0.6*1.3 and about 150KVAR, the capacitor requires 350KVAR, the capacity is not small. There is also a problem. It is difficult to start the motor and turn the capacitor on and off synchronously. For example, if the capacitor is inserted and the load is not turned on, the voltage will rise instantly, the generator will seriously move forward. in phase, or even lose magnetism. Change it to frequency conversion.
For drought-resistant soil irrigation: What size submersible pump should the generator be equipped with?
Please use it with caution.
The main component of the submersible pump is the motor. Starting the motor has the particularity of requiring a significant starting current, which is approximately 3 to 7 times the rated current. Calculated, a 1.5 kW motor requires at leastminus a 7 to 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 the water. The main objective of using this method is to avoid starting under heavy load. If it can continue to work, it means that the motor has high quality and good performance; if it still trips due to overload, you can only switch to a highpower.
1 horsepower is approximately 0.746 kW (kilowatt, what we call “degree”). If multiplied by a conversion efficiency of 80-90%, your diesel engine can achieve 18X0. 746X0.8=10.74KW, which means it can drive about 11KW generator, so the submersible pump you choose only needs to be less than 11KW.
However , according to the actual situation, you do not need such a powerful water pump. You can go to the market and take a look. I think a 3KW submersible pump is basically enough for you. The configuration you need is: 10m lift, and the water volume can be large or small.
