dump trailer speed control

[windboarder]

If a larger cylinder is used I would suggest lowering the pressure so that you don’t bend or destroy your dump trailer.

Lift force = pressure times cylinder area

Examples
1 1/2 inch bore and 2000 PSI = 3500 lbs

2 1/2 inch bore at 2000 PSI = 9800 lbs

Is that as easy as lowering the Relief valve on the pump?

Yes, system pressure is limited or set by the relief valve


To figure cylinder velocity

Flow = velocity times area

Flow = GPM x 231/60 = cubic inches second
Velocity inches per second
Area square inches

can you tell me if my math is close 19.4 seconds for 3x14 bore 13.59 for 2.5x14 bore

yes, those times look close.

for reference: double the diameter = four times the area so a 3 inch cylinder will be 4 times slower than an 1 1/2 cylinder

Me as well.

It must pivot close to the center and not take much force to dump.
