Methods to improve the displacement range of the screw pump

【Pump Network in Asia】 The following is the main introduction to improve the displacement of the screw pump range. Methods to increase the displacement range of screw rod method First, to expand the speed Fan 闱 This method to improve the displacement of the screw pump is the most direct way, but this method also has some drawbacks, it will increase the load on the pole, increase In addition, the stator, rotor and pole will also increase the wear and tear on the tubing, so to speak, this method is subject to certain restrictions. Second, to improve the structural parameters (such as increasing the rotor eccentricity, stator lead, etc.) This method to improve the displacement range of the screw pump is required according to screw pump displacement calculation formula to increase the rotor eccentricity, so as to improve However, this also has the disadvantage that increasing the eccentricity leads to an increase in the diameter of the rotor section and to an increase in the diameter of the pump. In addition, due to the limited downhole space, this also determines The limits of increasing the pump displacement by increasing the eccentricity are limited. Method three, increase the number of pumps This method is a more efficient method of displacement range of high screw pumps, but there are also some restrictions. Method 4, the use of electric submersible screw pump Although the use of electric submersible screw pump can greatly increase the speed and increase displacement, but also to reduce the rod string, but the former stator rubber fatigue temperature and wear When the performance will make the increase rate of speed subject to certain restrictions.
