SIMULATION OF OPERATION OF PNEUMATIC COMPENSATOR WITH QUASI-ZERO STIFFNESS IN THE ELECTRIC CENTRIFUGAL SUBMERSIBLE PUMP UNIT

Simulation of operation of pneumatic compensator with quasi-zero stiffness in the electric centrifugal submersible pump unit

The ECSPU pneumatic compensators with quasi-zero stiffness are proposed.The pneumatic compensator with quasi-zero stiffness is suggested to be made in the form of pneumatic spring assemblies having a power characteristic with a positive stiffness working area and a set of successively connected Belleville springs and a power characteristic with a w
