Can a pump run from a portable gasoline power station?

Good day! There is a vibration pump “Rodnik” - power consumption is 225 watts, 3.5 amperes. Is it possible to work from a portable gas power plant with a capacity of 850 watts? From a network of 220 volts it works perfectly, but every time I'm tired of pulling an electric wire up to 500 meters from the apartment to the garden (to the stream).

I am 68 years old. I will look forward to your answers to my question.

    Hello Anatoly!

    The capacity of an autonomous power plant should be equal to or greater than the total capacity of all energy consumers + 20% for the reserve. If you connect only a 225 W vibration pump to the power plant, then its 850 W power is enough for uninterrupted operation of the unit.

    When operating the pump from a portable power plant, you may encounter two problems:

    1) For most power plants, the optimal mode of operation is at a load of 40-80% of the nominal. In your case, it is 340-510 watts. For a short time, not more than 5 minutes, the electric generator can operate with increased (up to 110%) and with reduced (25-40%) load. Continuous operation in non-optimal load mode will lead to premature wear of the induction motor. Your pump gives the station a load of 25% of the rated power, i.e. the engine runs in uncomfortable mode. This problem can be solved very simply. It is enough to use additional electric consumers with a power consumption when the pump is operating, which in total with the pump will be the required 340-510 watts. When calculating, do not forget about the reserve + 20% for each consumer!

    2) When starting the pump from the power plant, inrush currents occur several times higher than the rated ones. Information on inrush currents can be found in the passports of both devices. Rodnik vibration pumps are equipped with an automation system that shuts off the unit in case of overload. Those. Your pump may not start. In this case, it is recommended to purchase a soft starter - soft starter. The cost of the device is from 2000 rubles. The soft starter is built into the line between the pump and the station and during the starting time (approximately 20-30 seconds) gradually raises the voltage. At this time, direct current is transmitted to the coil, an electromagnetic field is created and the equipment starts to work.In general, the use of soft starters significantly extends the "life" of pumping equipment.
