This document discusses hydraulic circuits and systems. It describes different types of gas loaded accumulators including non-separator, separator, piston, diaphragm, and bladder types. It lists several applications of accumulators such as damping pulsations and shocks, increasing operational circuit speed, clamping devices, standby power supplies, surge reduction, and vehicle suspension. The document also discusses pressure intensifiers which are used to boost hydraulic system pressure above the pump discharge pressure, finding application where high pressure liquid is needed from a low pressure source, such as hydraulic presses.

HYDRAULIC CIRCUITS

18.  Pressure intensifiers, also known pressure
boosters are used to compress the liquid in a
hydraulic system to a value above the pump
discharge pressure.
 An intensifier is a device which converts a
large-volume, low-pressure fluid supply into
a proportionately small-volume, high-
pressure fluid outlet.
 It finds its application at places where a
liquid of very high pressure is to be
developed from available low pressure.
 Its used to hydraulic presses, riveting m/c.
spot welders.
