TYPL series explosion-proof permanent magnet variable frequency motor and an intelligent variable frequency control cabinet.
It is an integrated device for an oilfield progressing cavity pump (PCP). A high-efficiency and the energy-saving product developed by the pumping unit, which is a new type of research and development based on the continuous development of power electronic devices, computer technology, and rare earth permanent magnet materials。
The system uses a vertical hollow shaft high-efficiency permanent magnet variable frequency motor to directly drive the screw of PCP. The reducer part is removed, which reduces energy consumption and reduces maintenance costs; At the same time, the oil well sealer is moved from the wellhead to the upper end of the motor, which makes the maintenance more convenient and simpler.
The high-efficiency permanent magnet frequency conversion motor is controlled by an intelligent frequency conversion cabinet. The system structure is simple, easy to adjust parameters, high efficiency, and has flexible protection after a power failure, shutdown, and fault alarm.
Reversal, power generation braking, low-temperature automatic heating and anti-condensation, high-temperature automatic cooling, over-torque, over-voltage, over-current, and other protection functions are key products to promote.
The system is suitable for PCP in oil fields with high viscosity, high sand content, and high-water content.
