LGBP series of variable frequency drive (VFD) switchboard for progressive cavity pump (PCP) unit, developed by Dongying Orientsun Electric Co. Ltd, equipped with the automatic measuring and controlling instrument for fluid level, can automatically adjust the motor speed as per the fluid level. The motor speed may be automatically decreased when the well fluid is insufficient. The function can effectively prevent PCP burning accidents caused by pumping out, and the energy saving effect is also remarkable. The switchboard has two control modes of variable frequency and fixed frequency.
