Pressure accumulator structure

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. The external source can be an engine, a spring, a raised weight, or a compressed gas.An accumulator enables a hydraulic system to cope.

Understanding the Function of Accumulators

The highest pressure that the accumulator will see. Each of these pressures provides information about the hydraulic system. If the accumulator is fully charged (is holding the maximum amount of hydraulic fluid), the maximum system pressure reading is p 2. If this reading is too high or too low, the controlling relief valve or pressure

This structure not only makes the system output stable speed and power, but also avoids the pressure shock in the main circuit caused by the release of the accumulator. At the same time, the additional auxiliary pump can directly apply torque to meet the control requirements of the system under different working conditions.

Hydraulic Accumulators Structure, Types And Usage

A gas-charged accumulator is filled with a compressed gas - usually air or nitrogen. A pump pumps a fluid into a cylinder. Compressed gas is pressed through a valve to a cylinder and it regulates pressure of fluid. In direct contact accumulators, gas has a direct contact with fluid. In case of piston, diaphragm and bladder accumulators, gas is
