Hệ thống bơm PCP

Chi phí vận hành thấp, bảo trì ít và hiệu suất cực cao: Nhờ hệ thống bơm PCP của NETZSCH, có thể bơm mọi loại chất lỏng từ dầu nhẹ đến dầu thô có hàm lượng cát, nước và khí cao ở áp suất và lưu lượng ổn định. Ngoài ra, bạn còn giảm đáng kể nhu cầu năng lượng. PCP là viết tắt của bơm khoang tiến triển. 

The composition of crude oil is as varied as its density. Light oils with an API grade of 31 or higher to heavy crude oil with an API grade of less than ten are common in oil and gas production. The occasionally high sand, water and gas content quickly pushes most pumps to their limits. However, this is not the case for PCP pump systems from NETZSCH. Thanks to the innovative design, they pump effectively even in low-quality oil fields. In a PCP pump system, the stator is usually inserted into the well at the lower end of the production pipe, while the Rotorrotor, Rotors, rotorsrotor is connected to the lower end of the suction rod. By rotating the rod string using a surface drive system, the rotor turns within the stationary stator, creating the pumping action required to deliver fluids to the surface. Due to the small outer diameter, installation is straightforward and cost-effective.

PCP pump systems impress with high efficiency

In addition to pumping at a constant pressure and flow rate, PCP pump systems can work almost without pulsation and shear force. Therefore, emulsion effects in the oil-water mixture are avoided. This makes separating the oil-water mixtures at the surface much more accessible. However, the key advantage of the progressing cavity pump system is its extremely high efficiency. This makes even pumping under the most challenging conditions effective again. For example, the volumetric efficiency of a borehole progressing cavity pump is between 75 and 90 percent, which is significantly higher than that of conventional pumps. Electric submersible pumps or the frequently used horsehead pumps sometimes only have an efficiency of less than 35 percent.
