Petroleum Pump

Its technology is originated in China. Used in petroleum extraction, it has advantages of energy conservation, consume reduction, long service life, convenient installation and high output. Thus it reduces the lifting cost dramatically. Our major customers are Daqing, Dagang, Shengli, Liaohe oil fields. (Its full name: ZQLB Direct Drive Submersible Screw Pump) The screw pump is set thounds meters underground and fastened on the pipeline. Length specification: Motor: 9.83 m Protector: 3.3 m Flexible shaft: 1 m Screw pump: 5.5 m Performance parameters of ZQLB direct drive submersible screw pump Technical parameters of the electrical cabinet of ZQLB direct drive submersible screw pump Advantages: 1. No sucker rod, thus the loss from its abrasion is eliminated. 2. The three-loop control method including position loop, speed loop and current loop is used in the management system to suit for different well conditions. 3. Slow speed of revolution of 50-500 rpm, large torque over 500Nm. 4. Less possibility of vapor lock , with the capacity of emulsion breaking. 5. Pumping continuously and steadily. 6. Applicable to vertical shaft, inclined shaft, horizontal well, especially the beam pumping wells. 7. Suitable for exploiting crude oil of high viscosity,high sediment and high oil-gas ratio. 8. Delivery volume: 10 150m3 /d, delivery lift: less than 2000m, and working temperature:≤150°C. 9. Simple installation due to removal of 1000-metre-long sucker rod. 10. Energy saving and consume reduction.
