1. Conveying Crude Oil: In 2010, the CSG214J2I-80/640 double-headed single screw pump was used for crude oil conveying at Changguanmiao Union Station of Wuqi Oil Production Plant in Yanchang Oilfield. The pump’s flow is 80m³/h, pressure is 6.4Mpa, motor power is 200kw, medium temperature is ≤80 ℃, equipped with frequency conversion.

Effect: This is a high-pressure double-headed single screw pump for crude oil transportation, which fully meets the process requirements for crude oil transportation, saves energy, is easy to use and maintain, and has low operating costs.


2. Conveying of Crude Oil: In 2015, the CS22002I-260/250 CS double-headed single screw pump was used for conveying crude oil at Qinghai No. 1 Oil Production Plant. The pump’s flow is 260m³/h, the pressure is 2.5Mpa, the medium temperature is ≤70 ° C, and its motor power is 280kw, under an altitude of 2800 meters, equipped with frequency conversion.

Effect: This pump is the world's high-flow and high-pressure crude oil pumping unit. It is not afraid of sand and impurities, and adapts to the working conditions with large changes in liquid volume. The pumping unit has the advantages of good suction performance, energy saving, and convenient use Low operating costs.


3. Oil and Gas Mixed Conveying: In 2007, the CS21I-400/160 single-head single screw gas-liquid mixed pump was applied to the gas-liquid mixed transmission of No. 56 Station of Zhongyuan Oilfield Production Plant No. 2. Its flow is 400m³/h and the pressure is 1.6Mpa, gas-liquid ratio 1:50, equipped with closed-loop fully automatic control.

Effect: This pump set is still the largest single-screw pump set in the world at present. It has been in running for more than 10 years, and it is suitable for large oil and gas working conditions.


4. Oil and Gas Mixed Conveying: In 2012, CSY22402I-350/160 double-headed single screw gas-liquid mixed transportation pump was applied to the gas-liquid mixed transportation of Weigang Mine in Henan Oilfield. The pump’s flow is 350m³/h, pressure is 1.6Mpa, its gas-liquid ratio 1:30, closed-loop fully automatic control.

Effect: This pump set is still the world's largest double-head single screw pump set. It has been running for 7 years, saves energy, is easy to use and maintain, with low operating cost, and has a significant effect on reducing back pressure at the wellhead.


5. Polymer Conveying: In 1998, the CS15I-100/200 single-head screw pump was applied to the Saltu injection polymerization station of the No. 1 Oil Production Plant of Daqing Oilfiel. The pump’s flow is 100m³/h,  pressure is 2Mpa, and adopts rigid stator and our equal wall thick stator.

Effect: High single-stage pressure, short pump set size, low energy consumption, good suction performance, strong resistance to the system, and low operating costs.


6. Polymer Conveying: In 2009, the CS21602I-150/250 double-head single screw pump was used in the polymer injection station of the test team of the No. 6 Oil Production Plant of Daqing Oilfield. Its flow is 150m³/h, the pressure is 2.5Mpa, and the polymer injection viscosity is ≤5000mpa .s.

Effect: This is a large-displacement, high-pressure pump unit in the polymer injection field, with good suction performance, energy saving, and convenient use and maintenance.


7. Sewage Oil and Sewage Conveying: In 2010, the CS21802I-200/160 double-head single screw pump was applied to the sewage treatment station of the No. 3 Oil Production Plant of Daqing Oilfield. Its flow is 200m³/h, and the suction depth of the pressure is 1.6Mpa. The suction is 4m.

Effect: Good suction performance, adapt to different viscosity and changing working conditions, changed the traditional sewage and oil conveying process, energy saving, easy to use and maintain.

 

8. Offshore Platform Crude Oil Conveying: In 2011, the CS214LI-200/80 double-headed single screw pump was applied to the Bohai offshore platform for crude oil transfer. The pump’s flow is 200m³/h and the pressure is 0.8Mpa.

Effect: The pump set has low vibration and noise, wide speed range, energy saving, and is certified by the Classification Society.
