 Savings hydraulic pressure can be used (1) for the intermittent load, can reduce the transmission power of the hydraulic pump when the hydraulic cylinder needs more oil, accumulator, hydraulic pump, while oil; when the hydraulic cylinder does not work, the hydraulic pump to the accumulator oil filling, the pr essure reaches a certain hydraulic pump stops running (4) to maintain system pressure: to supplement the hydraulic system oil, or hydraulic pump used for a long time to stop running to maintain constant pressure on the device (2) in an instant pressure oil (5) to drive the secondary circuit: mechanical adjustment maintenance and other reasons, hydraulic hose crimping machineleaving the main loop to stop, you can use the hydraulic accumulator to drive the secondary circuit (3) emergency operation: hydraulic equipment failure and power outages steady pressure, as an emergency power source (6): in the latch circuit, due to the temperature rise leaving the expansion of the liquid, to produce high-pressure accumulator can be used to absorb the volume changes resulting from falls in the oil, can also play a compensation role to ease the impact and eliminate pulsation (1) absorb the pressure of the hydr aulic pump pulse (2) ease the shock: such as easing the valve quickly shut down and change hydraulic banjo fittingsdirection when caused by water hammer phenomenon Note: (1) to ease the impact of the accumulator, should be used in small inertia accumulator, such as Bladder type accumulators, spring-loaded animals can, etc..

     (2) to ease the impact of the accumulator, generally installed in as far as possible close to the shocks occur, and vertical mounting port down. Faithfully, subject to location restrictions, vertical installation can not be installed horizontally.

     Accumulator installed in the pipeline, must support plate or bracket accumulator tighten to avoid an accident.braided hose fittings

     4. Accumulator should be in stalled away from sources of heat to place.
