The multi-stage centrifugal pump for mine installation of the frequency converter can make the constant speed submersible pump a variable speed and high speed water pump, which makes the pump suitable for normal operation in different situations.
Advantages of variable frequency water pump:
1. The deep well situation is complex and variable. The frequency conversion speed regulation improves the flexibility of the water pump. Adjusting the frequency of the frequency conversion device can increase the viscosity of the well fluid and reduce the frequency, so that the production of the submersible pump is always in an optimal state to ensure that the motor is not overloaded.
2. Reduce the number of repairs and save the cost of downholes and wells.
3. The three-phase submersible motor is fully pressurized, the starting current is about 4-6 times the rated current, and the current is too large, so that the generator will burn out. However, the frequency conversion device can be started at low frequency and low voltage, and the starting current is about 1.5 times the rated current, which can reduce the damage to the motor. In addition, when short-term overload, the frequency conversion device automatically reduces the frequency, reduces the number of starts of the shutdown, and can extend the life of the pump.
4. The frequency conversion speed regulation can make the water pump in the best state, and solve the problem that the power consumption is the same when the water pump flow rate is low, so that the energy saving purpose can be achieved.
5. The water pump is in unclear geological conditions, and the well conditions change greatly during operation. At this time, frequency conversion speed regulation is required to make the water pump in an optimal state and flexible work.
