What is a HYDAC system?

1. GENERAL In a back-up version with nitrogen bottles to increase the efective volume The HYDAC system approach creates a HYDAC system of, for example, bladder or piston accumulator stations, by integrating individual HYDAC components. The modular design of the accumulator stations enables HYDAC to incorporate all customer requirements.

What is a hydraulic accumulator?

A hydraulic accumulator is a pressure storage reservoir in which an incompressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy.

What is a compressed gas accumulator?

It is a type of energy storage device. Compressed gas accumulators, also called hydro-pneumatic accumulators, are by far the most common type. The first accumulators for William Armstrong 's hydraulic dock machinery were simple raised water towers. Water was pumped to a tank at the top of these towers by steam pumps.

Where is the accumulator located in a multi-piston pump?

An accumulator is placed close to the pump with a non-return valve preventing flow back to the pump. In the case of piston-type pumps this accumulator is placed in the ideal location to absorb pulsations of energy from the multi-piston pump. [citation needed] It also helps protect the system from fluid hammer.

How can HYDAC calculate accumulator volumes?

Taking the customer’s own operating data into account, HYDAC can calculate the required accumulator volumes using the accumulator simulation program: z ASP – Accumulator Simulation Program. Please read the relevant operating instructions for the individual HYDAC components! 2. MODEL CODE 3. EXAMPLES OF ACCUMULATOR STATIONS 3.1.

How does a cylinder accumulator work?

The cylinder is closed by a piston on which a series of weights are placed that exert a downward force on the piston and thereby pressurizes the fluid in the cylinder. In contrast to compressed gas and spring accumulators, this type delivers a nearly constant pressure, regardless of the volume of fluid in the cylinder, until it is empty.
