can the accumulator speed up the cylinder
Charged Accumulator
This accumulator operates in a manner similar to the bladder type. Accumulator Sizing. Most accumulator systems should be designed to operate at a maximum oil pressure of 3,000 psi. This is the rating of most accumulators and will give the maximum effect for the least cost. Also, 3,000 psi is the maximum rating for most hydraulic valves.
Hydraulic Accumulators: What Are They and Why Do We Need …
Essentially, an accumulator is a vessel containing a bladder and gas so that as the bladder fills with pressurized hydraulic fluid, the gas compresses inside the vessel. When the fluid in the accumulator is released, the compressed gas pushes out the fluid. The accumulator will come preloaded, which means a minimum pressure is …

This example shows how a compound relief valve can be used to limit maximum pressure and unload the pump when the desired accumulator pressure is reached. When this happens, a pressure switch triggers a valve that ventilates the compound relief valve. When the load moves, the accumulator discharges and eventually the pressure switch flips back.

Accumulator (energy)
An accumulator is an energy storage device: a device which accepts energy, stores energy, and releases energy as needed. Some accumulators accept energy at a low rate (low power) over a long time interval and deliver the energy at a high rate (high power) over a short time interval. ... Various devices can store thermal energy, mechanical ...
Hydraulic accumulator
Hydraulic accumulator. 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. [note 1] An accumulator enables a hydraulic system to ...

why does no one use a hydraulic accumulator to speed up the hydro log splitter
I think there are just to many better ways to speed up a splitter without using a accumulator. These ways are much less complicated as well. The only possible reason I can see to use a accumulator on a splitter is to decrease cycle times. this can be done much more efficiently buy matching the correct parts when doing the build.
