Accumulators can be useful to the plant engineer. Hydropneumatic or gas-charged version are used effectively in hydraulic circuits for auxiliary power, energy storage, emergency operation, leakage compensation or makeup fluid, and motor soft starts. Accumulators are also applied for shock absorption in pressure and tank lines, pulsation dampening, elimination of pump cavitation, and noise attenuation. The first reaction to a malfunction in a hydraulic circuit is to check the pump and valves. Many times the problem may be flow related, either too much or too little. Jeffrey B. Mordas of Hydac Corp. explains how an accumulator resolves difficulties with fluid circuits and provides auxiliary power, energy storage, shock absorption, pulsation dampening, and noise attenuation.
