Safety Equipment for Hydraulic Accumulators
Hydraulic accumulators are pressure vessels, as defined by PED 97/23/EC, and as such their manufacture is subject to the statutory pressure equipment regulations.
Therefore, for safety in the workplace, system manufacturers and operators must draw up a risk assessment for the particular site.
These must take into account possible risks at the installation site, particularly in combination with external factors.
Fundamental risks affecting hydraulic accumulators are:
- Excessive pressure and
- Temperature increase (e.g. in the event of an external fire).
HYDAC provides the appropriate safety equipment to protect accumulators from excessive values on the gas and fluid side; see also catalogue section: Accumulators No. 3.000.What's more, HYDAC safety devices have a CE marking and are shipped with a declaration of conformity. A gas safety block simplifies the operation of hydraulic accumulators on the gas-side and also provides a means of attaching the above safety equipment using the various ports.
