Emulsion Pump Use Frequency Inverter

Product Description

Frequency Converter for Emulsion Pump

1. Product Introduction
BPJ1-315(400)/1140R series mine explosion-proof and intrinsically safe emulsion pump inverter is a high-tech product integrating all-digital frequency conversion speed regulation technology and related heat dissipation technology. This product is suitable for the control of emulsion pumping station with AC 50Hz, motor power 110KW~400KW and rated voltage 1140V. It can handle the dynamic process during sudden unloading, and the DC bus voltage suppression of the inverter is more stable and the current fluctuation is small. In addition to limiting the voltage and current fluctuations of the busbar, the acceleration and deceleration time of the special inverter for the emulsion pump can be set to 5 seconds for the characteristics of rapid pressure drop of the emulsion pump, that is, the inverter accelerates from zero speed to 50Hz full speed at full speed. The time is only 5 seconds, which makes the pressure follow better.


2. Product range
This product is applied to the frequency conversion speed control of emulsion pump equipment.
