PULSCO’s Hydropneumatic Bladder Surge Control System
designs are developed from a proprietary program developed especially
for surge control analysis to model the fluid system and offer
a low cost alternative for small water system application. From
this analysis, the correct surge tank and components can be sized
and determined. The result is a complete and accurate account
of system requirements and a reliable solution design for any
transient flow problem.
The Bladder Surge Control System controls the energy and thus
minimizes transient pressure from the shock waves. The system
is pre-charged to a calculated pressure that will resupply
the system with water after a pump station shut-down or start-up
procedure. Either the bladder will be charged for waste water
type applications or the tank will be charged for potable water
applications. Complete protection of the fluid system may require
multiple bladder surge control systems depending on the allowable space.
The principal components of the system are the ASME tank, bladder,
safety valve, pressure gauge assembly and air charging valves. The tank is
designed, built and certified to ASME Sec. VIII, Div. 1 requirements.
The tank volume and design pressure is determined by the system's
requirements and horizontal or vertical arrangements are possible
with capacity ranging from 120 to 8,000 gallons, or to customer
specification. The bladder is a heavy duty FDA grade Butyl Rubber.
An optional PULSCO Bladder Failure Alarm provides local and remote alarm indication for a ruptured bladder. |
