Energy accumulator for emulsification pump

Why do hydraulic pumps use accumulators?

As energy storage, accumulators typically allow the hydraulic system to use a smaller pump because they amass energy from the pump during periods of low demand. This energy is available for instantaneous use, and is released on demand at a rate many times greater than what could be supplied by the pump alone.

How can accumulators reduce pump size?

By using the resulting high-pressure hydraulic fluid to charge an accumulator, the stored energy in the accumulator can then be used to supplement pump flow when it is time to raise the excavator arms and their load. This energy recovery approach makes it possible to reduce pump size by 25%.

How does a hydraulic accumulator work?

Supplementing pump flow — An accumulator configured for storing power can supplement the hydraulic pump in delivering power to the system. The pump stores potential energy in the accumulator during idle periods of the work cycle. The accumulator transfers this reserve power back to the system when the cycle requires emergency or peak power.

How can accumulators reduce the size of a hydraulic system?

Supplementing pump flow In many hydraulic systems where high flow is required for a short duration, followed by a few seconds of dwell time, the size of pumps and electric motors can be significantly reduced by incorporating accumulators into the system.

How do accumulators work?

This energy is available for instantaneous use, and is released on demand at a rate many times greater than what could be supplied by the pump alone. As a pulsation or surge damper, accumulators cushion the hydraulic hammer, reducing shocks caused by rapid operation or sudden starting and stopping of cylinders in a hydraulic circuit.

How does insulating a gas accumulator improve system efficiency?

Insulating the accumulator and associated piping can further improve system efficiency by capturing heat energy. When gas is compressed, it heats up. When it expands, it cools down. For mobile equipment that sits idle for a few minutes, or until flow is needed, the heat is lost to the surrounding atmosphere.
