The fountain submersible pump characteristics
1) start
Fountain submersible water pump should have faster start and stop response speed to facilitate the performance of water type. Its rotating inertia is less than the normal products, the design needs to improve the starting torque.
The submersible pump for fountain is often in the working state of approximately frequent starting, and the electromagnetic parts should have lower magnetic resistance; the winding line should withstand frequent current impact; the heat dissipation ability of the motor should be higher than that of the well pump design.
2) Low voltage operation capacity:
The total amount of fountain industry submersible cable is large, the cable cost accounted for a higher proportion of the project cost, to reduce the line voltage by increasing the section area of cable drop will bring material costs increased substantially. Therefore fountain submersible pump with characteristics of low voltage work better.
3) Horizontal installation:
The dewatering pumps in fountain projects often need horizontal installation, the existing structure cannot guarantee a long service life, especially large submersible pump. Need to design horizontal installation of submersible pump, the service life should be the same of the vertical pump life.
4) Frequency conversion characteristics:
The frequency transformer has been widely used in the fountain industry, the transformer works output is not a positive spin wave, will cause the rotor vibration, the motor bearing will easily wear out. High frequency harmonics also lead to heating the silicon steel plate, increase the temperature goes up of the motor. The cable of submersible pump is all very long, with large capacitance, when the inverter works, the high frequency harmonic will form high voltage pulse with the motor reactance and the line capacitance resonance. It will easily lead to the breakdown of the motor insulation.
