Use-case Pumps

Progressing cavity pumps, also known as eccentric screw pumps or Moineau pumps, are a type of positive displacement pumps used for pumping high-viscosity liquids, sludge, or abrasive materials. They consist of a rotary part, the eccentric screw (a helical rotor), and a stationary part, which is made of an elastic material and has a double helical winding.

The optimization of progressing cavity pumps may include several aspects:

Efficiency improvement: This can be achieved by enhancing the design of the screw and stator, selecting appropriate materials, and improving manufacturing processes.

Extended lifespan: The pump’s lifespan can be extended by using durable materials, improving maintenance processes, and reducing wear on the screw and stator.

Adaptability: The pump’s ability to handle a variety of liquids can be enhanced by adjusting the design and materials of the screw and stator.

Operating cost reduction: This can be achieved by improving energy efficiency, reducing maintenance costs, and extending the pump’s lifespan.

Simulation and modeling play a crucial role in the optimization of progressing cavity pumps, as they allow testing and optimizing various design and operational parameters without the need for costly and time-consuming physical tests.

Initial Situation:

The optimization of progressing cavity pumps is based on iterative design, manual adjustments, engineering experience, and real tests to improve performance.

Problem area

Main problems include high time consumption for manual adjustments, material waste, and strong dependence on the individual expertise of engineers.

Goal

The goal of using simulations is to gain insights into pump operation to optimize design and performance. This allows for the reduction of experiments, cost-saving, and efficiency improvements.

Relevant KPI’s

– Pump efficiency: Measurement of the ratio of delivery rate to the energy expended.
