Working principle

According to the size of the force required to determine the piston rod on the thrust and pull. In this way, the output force of the cylinder should be slightly margin. If the selection of small bore, the output power is not enough, the cylinder not working properly; but the diameter is too large, not only the heavy equipment, high cost, and the gas consumption increases, resulting in energy waste. In the design of the fixture, the force amplifier should be used as much as possible to reduce the size of the cylinder.


The following is the formula for calculating the theoretical output of the cylinder:

FTheoretical output force of cylinderkgf)

F′Efficiency is85%Output force of timekgf)--(F′=F×85%

DThe cylinder bore (mm)

PJob stresskgf/C㎡)

Example: diameter340mmThe working pressure of the cylinder is3kgf/cm2How much is the theoretical output??How much is the bud output??

takePDConnect, find outFF′On the point, get:


stayengineeringDesignWhen choosing the cylinder, according to the use of pressure and theorythrustOr the magnitude of the pull, from the empirical table11Find out.

Example: there is a cylinder whose working pressure is5kgf/cm2When the cylinder is pushed out, its thrust is132kgf(cylinder efficiency is 185%Q: the choice of) much of the cylinder?

Thrust from cylinder132kgfEfficiency of cylinder85%The theoretical thrust of the cylinder can be calculatedF=F′/85%=155(kgf)

By the use of pressure5kgf/cm2The theory of thrust and cylinder bore, found selection?63The cylinder can meet the use requirements.
