NOLE TJNB3000 Series Energy Saving Frequency Coverter

Product Description

The dedicated energy-saving frequency conversion controller of TJNB***0 series pumping unit is used for oil field pumping unit energy-saving control, during the working process of the pumping unit, the upstroke is a process that needs electric energy and the downstroke is a gravity dropping power generation process. In the upstroke, it is “big horse pulls a small carriage”, therefore the motor has excess power supply to the pumping unit, and the energy-saving frequency conversion controller can save the surplus motive power, thus achieving energy conservation goals. In the downstroke of the pumping unit, it is the power generation process of the motor, the energy-saving frequency conversion controller returns its generating power to the power grid is a power recovery process by changing the original power consumption into power generation process, therefore, the energy-saving effect is even more prominent that realizes energy-saving and emission reduction effect in genuine.
