The Pulsating Stroke Box Structure Improvements of SSS-Type Vertical Ring and High Gradient Magnetic Separator
This paper describes the pulsating stroke box’s role in the process of magnetic separation,and its some improvements on structure in order to optimize performance and enhance its service life: the support structure of reciprocating shaft,the sealing of reciprocating shaft’s stretched side and the stroke adjustment.The improved pulsating stroke box structure is stable performance,compact,easy to use and long life.
The author discusses the stability of the slip power recovery generator (SPRG), in open loop and in closed loop, for applications like the exploitation of ocean wave energy by water column devices. The stability study was performed using small displacement models for each of the following situations: SPRG in open loop, SPRG with inner current loop, and SPRG with active power regulation. Numerical results obtained for an experimental 3.2 kVA prototype are presented. >
