Experimental Studies of the Influence of Configuration of Regular Microrelief of Plunger Surface on Sucker-Rod Pump Delivery

Аннотация

The influence of configuration of regular microrelief on leakage of fluid pumped through plunger pair of sucker-rod pump is studied. An experimental unit developed to study fluid leakage through plunger pair is presented. The experimental data and the results of simulation in ANSYS CFX of leakage through plunger pairs with and without microrelief are given. Practical recommendations are offered on the choice of geometric parameters of plunger pair grooves for minimizing leakage.
