SCHWERLL piston accumulator system with energy monitoring for emergency hydraulic power-source applications. Manufacturer information cites >=9 MPa as a high-pressure application context; final system ratings, monitoring architecture and supply scope require project-specific confirmation.
Overview
SCHWERLL’s Piston Accumulator System with Energy Monitoring Device is presented for emergency hydraulic power-source duties where stored accumulator energy must remain under monitored operating conditions.
Emergency application context
Manufacturer-published application examples include emergency actuation of hydraulic-turbine governor servomotors, emergency closing of chemical-process and hydropower inlet valves, and circuit-breaker operation after loss of power.
High-pressure application context
The manufacturer also cites high-pressure applications, for example where system pressure is >=9 MPa, as a context for selecting a piston-type accumulator system equipped with an energy-monitoring device. The >=9 MPa statement is an application/system-pressure example and does not establish the product’s working, design, allowable or maximum pressure.
Configuration confirmation
Exact monitoring architecture, measured variables, sensor types, signal interfaces, vessel configuration, system volume, pressure ratings, hydraulic media, precharge, testing and conformity scope require confirmation for the supplied project configuration.
