High Pressure Piston Accumulator with Crimped Design- HCP Se

产品概况：

The high pressure piston accumulator (HCP) incorporate a patented crimped design that provides high-strength coupling of caps to steel tube plus superior fatigue life. High grade carbon steel tube and end cap material allows heat to dissipate effectively and is micro-finished for extended seal life.

Parker’s high pressure crimped piston accumulators (HCP series) are an ideal replacement for applications whereby membrane (also known as diaphragm) accumulators are utilized. One piston accumulator can deliver the same performance as five or more membrane accumulators. Reducing the number of required accumulators from five or more to just one piston accumulator will reduce components such as hoses and connectors and will;
* Reduce potential leak points
* Generate additional space
* Minimise installation time
* Reduce maintenance.

Although these accumulators are offered in standard capacities, the steel shell design affords an easy way to "custom" manufacture an accumulator to meet the exact capacity for any customer application.

Parker have developed very sophisticated simulation software to optimize sizing recommendations for hydraulic accumulators. You can download the accumulator sizing software from the Product Support tab.

• Cushioning
• Energy Storage

Function:
Hydraulic accumulators are an essential component for the optimum operation of a hydraulic circuit. The accumulator enables:
• Energy Storage: Saves energy without loss and redistributes when required therefore reducing installed power.
• Pressure Compensation: Absorbs pressure spikes from pumps or other components to control pressure and flow rates in the hydraulic circuit.
• Volume Control: Absorbs fluid volume variations induced by temperature changes in a closed hydraulic circuit and maintains a rated pressure.
• Emergency Energy Storage: In case of failure of the main energy source, these accumulators can provide sufficient energy to complete an operation or to realize a full hydraulic cycle.
• Hydraulic Spring/Shock Absorber: A piston accumulator can act as a gas spring suppressing shocks and vibrations in hydraulic systems of lifting vehicles (e.g. Forklift trucks) and maintains real suspension of the load on a gas spring.
