6 FAQs about [Ship hydraulic permanent accumulator]
What is a hydraulic accumulator?
Hydraulic accumulators are closed pressure vessels designed to store then discharge pressurised fluids. A hydraulic accumulator consists of a fluid section and a gas section with a gas-proof separation element between them.
In what form does a hydraulic accumulator store energy?
A hydraulic accumulator is a simple hydraulic device which stores energy in the form of fluid pressure. This stored pressure may be suddenly or intermittently released as per the requirement.
When might a hydraulic system need an accumulator?
An accumulator might be able to help you out if your particular hydraulic system is noisy or has vibrations, making it hard to read gauges and sensors, or if you need to maintain pressure while the pump is off. Not all hydraulic systems will require an accumulator.
Can hydraulic accumulators be soldered?
Hydraulic accumulators are subject to high pressures; therefore no welding, soldering or mechanical work can be carried out on them. HYDAC recommends that all hydraulic accumulators have a dedicated relief valve and a method of isolating and bleeding the accumulator as this will ensure the correct and safe application.
Do hydraulic accumulators need a CE stamp?
Hydraulic accumulators are not held to the same standard as the Pressure Equipment Directive (PED), so a CE stamp must not be applied to the vessel. However, the accumulator must be marked with 'SEP' on the label. Manufacturers may also offer dual-certified ASME/CE accumulators.
What is HYDAC accumulator technology?
HYDAC Accumulator Technology can reflect on over 45 years' experience in research & development, design and production of Hydac accumulators. Bladder, piston, diaphragm and metal bellows accumulators from HYDAC together form an unbeatable range and as components or units, support hydraulic systems in almost all sectors.
