The pressure and temperature influence oil density, viscosity, and modulus of elasticity. Their variation influences the flow through the piston-barrel interstitial to oil extraction pumps and the liquid flow that is lost through this gap. A model with 8 different liquid pressure zones was created in the LMS Amesim program to study fluid leakage through interstitial. The model is used in dynamic situations. The flow values of lost liquid are indicated and compared to the model with a single zone of liquid.
