In this video, discover the assembly of a pneumatic linear actuator designed to operate a knife gate valve. But before getting into the build, let\u2019s go over the basic physics behind correctly sizing a cylinder. <\/p>\n
\ud83d\udccc How to determine the required force?
\nThe key formula to know is:
\nP = F \/ S
\n\u27a1\ufe0f P: Pressure (in bar or Pascal)
\n\u27a1\ufe0f F: Force applied (in Newtons)
\n\u27a1\ufe0f A: Piston surface area (in mm\u00b2 or m\u00b2)
\nTo choose the right piston diameter, we invert the formula:
\nF = P \u00d7 S
\nDepending on the available supply pressure and the force required to operate the valve, we can calculate the necessary cylinder bore.
\n\u2699\ufe0f Example:
\nIf a pressure of 6 bar (600 kPa) is applied and a force of 3000 N is needed, then:
\nSurface area: A = F \/ P = 3000 \/ 600000 = 0.005 m\u00b2 (5000 mm\u00b2)
\nThis corresponds to a piston diameter of approximately 80 mm.<\/p>\n
