The present study deals with the experimental facility for PSD (POGO Suppression Device) performance test systems. Basically there are two methods to pulsate the system; whole-feeding-system pulsation and working-fluid pulsation. The latter method adopts either a piston-type pulsator or a restrict-type pulsator. The working-fluid pulsation using a restrict-type pulsator was considered to be the most appropriate experimental system to study the effects of the primary parameters, and a practical design of the system was proposed. Also, the experimental facility adopts the ball valve type pulsator considering the leak problem of the plate type pulsator.

In this Study, the types of PSD performance test systems were reviewed. And as a results of that reviewing process, a suitable PSD performance test system type for PSD design was proposed. PSD performance test systems can be classified with pulsating methods - the pulsating whole feeding system and the pulsating working fluid. The pulsating working fluid method can be re-classified with the devices of pulsating working fluid - a piston-type pulsator and a restrict-type pulsator. The pulsating-working-fluid performance test system with restrict-type pulsator was proposed to be a suitable type for identification of main-design-parameters.
