Direct-drive screw oil pump

Direct-drive screw oil pump

1.The motor can output the torque to the screw pump directly, leaving out complex decelerate and belt gearing system, do not need reverse braking equipments, reducing the cubage, without the bother of oil-leaking problem of the gearbox.

2. Step less speed change and intelligent modulating, the oil production of the screw pump matches the supply of the oil well, preventing over-pumping and insufficient-pumping, extending the service life, enlarging the production. Leave out the labor of replacing the belts and configuring the parameter. Reduce the labor intensity. Improve usage rate of the equipment.

3. Soft startup, soft stop, reverse brake, interval work, variable-speed work, good for reducing the abrasion and vibration of the pump, preventing reverse rotating and drop, reducing oil leak , extending service life of the screw pump.

4. The controller has protections of overload, over-voltage, over-current, short current, open phase, high temperature, low insulation. The parameter can be displayed so that the operator could know about the working situation. Remote monitor and intelligent management.

5 .Compared with the variable-frequency drive + Y type motors, the direct-drive motor removes lots of disadvantages such as small torque at low speed, small speed range, poor overload, with gearbox and belts, screw pump having side force, low efficiency. After the direct-drive motor being used, maintenance work is reduced, labor intensity is small, the performance is improved, and the product is becoming more competitive.

6. The system is high-efficient and energy-saving throughout the whole speed range, improving the efficiency by 30%~60% and reducing the cost. When selecting this kind of system, you can choose half as the power of the Y type motors. The power factor of the motor is nearly 1, improving the power factor of the network, leaving our compensators, saving transmission cost.
