Accumulator Main Usages

ENERGY STORAGE

1. Energy Storage

By installing accumulator (ACC), oil pump capacity can be downsized and idling operation of the electrical motor can be stopped. So, the initial cost for machineries can be minimized and electricity consumption can be reduced.
By the idling-stop operation of the electrical motor and the hydraulic pump, temperature rise of the system fluid is suppressed and cooler becomes no need of use. Also, prevention of the system fluid deterioration can be attained.
Accumulator can also be used as hydraulic pressure source on an emergency case such as hydraulic pump or hydraulic source equipment trouble or electricity failure.

2. FOR THE PRESSURE PRESERVATION

When the hydraulic pressure in the pipe line of the closed circuit changes in wide range due to the temperature change, the pressure can be stabilized to an almost constant level by using accumulator.
On the other hand accumulator can compensate for the pressure drop that will be caused by the oil leakage on the equipments these require to keep constant pressure condition for long time (Pressure maintaining circuit, etc.), and as the result, the pressure drop in such circuit can be minimized.

Shock Absorber

FOR SHOCK DAMPENING

Rapid opening and closing of valves can create shock waves in a hydraulic system. Installing accumulator that is also an "Energy Saving Equipment" near to the source of these shocks, the accumulator can absorb the shocks.
By decreasing the shocks in the hydraulic circuit, vibration and noise are damped, and premature failure to hoses, fittings, and other components can be prevented.

FOR PULSATION DAMPENING

Installing an accumulator near to the source of the pulsations created by such as pump etc. the accumulator (so called energy saving equipment) can attenuates pressure pulsations in the hydraulic line.

FOR THE TRANSFER BARRIER

A transfer barrier type accumulator can be used as a substitute for a hydraulic pump by transferring or transmitting fluids, with the bladder being operated as a piston to let a fluid flow into and out of the accumulator intermittently.

For Oil Tank Dust Prevention

Dynaclean has a function to protect the hydraulic fluid in the oil tank from contamination and oxidation.
