Connecting line between oil cylinder and accumulator

How do I connect the oil filter and accumulator?

Connect the oil filter, cooler and Accumulator in series as shown using –10AN lines and fittings. If a remote oil filter with a one way valve is not used, we recommend installing a one way check valve on the filter side of the accumulator. Charge the unit as described under CHARGING THE SYSTEM.

How does an oil accumulator work?

The accumulator then releases the stored oil on demand to complete the cycle, there by serving as a secondary power source. When the four way valve is manually activated oil flows from the accumulator to blank end of cylinder. This extends the piston until it reaches the end of the stroke.

How does hydraulic accumulator work?

When the cylinder is in its fully extended position, the accumulator is being charged. The four way valve is then deactivated for retraction of the cylinder oil flows from both pump and accumulator to retract the cylinder rapidly. 10. Discuss in detail the application of hydraulic accumulator for protection against shocks

How accumulator supplements the pump flow?

First we will see the how accumulator supplementing the pump flow, this is probably the most important application of accumulator in hydraulic circuits. During resting periods of the pump when oil is not needed to move the cylinder the pump can store oil under pressure in an accumulator.

When does oil go to accumulator?

Fluid only goes to the accumulator when pump flow is greater than the system requires. This circuit fills the accumulator anytime the cylinders stop or anytime required volume is less than pump output. There will be some heating of the oil while the accumulator is filling until system pressure reaches 1500 psi or above.

How do you retract a accumulator cylinder?

Pre-charge the accumulator to a pressure slightly higher than it takes to retract the cylinder. The cylinder will then retract when directional valve A and normally open, solenoid-operated relief valve H shift. (Also see Figure 1-34 .) The large piston rod reduces the return volume, although retract pressure will be higher.
