Piston Speeds

The feed flow or return flow speeds are calculated using the flows of liquid coming from the pump, which fill the stroke volume of the hydraulic cylinder within a certain unit of time.

For the speeds specified above, the following equations result under consideration of the usual units:

v=

Q


Ak

v=

Ar

Retraction

Please observe that the volume of liquid flowing away during the return flow is always greater than the inflowing liquid due to the difference in area. As a result, the return flow is faster than the feed flow. If the length of the cylinder stroke is known, the stroke time t can be calculated as follows.

t=

Ak * h
