The piston rod is used as an executing component in the cylinder. When the cylinder is working, if it is desired to determine the force of the piston rod to transmit torque and bear the load according to the force required for the work, the thrust and the pulling force are not indispensable. Therefore, it is very important for the thrust and tension on the piston rod. And the last time I edited and introduced what is the thrust and tension of the piston rod? Then I will introduce how to calculate the thrust of the piston rod.

 

 Cylinder piston rod thrust calculation formula: (ie theoretical output)

 

F: cylinder theoretical output force (kgf)

 

F': output force (kgf) at an efficiency of 85%--(F'=F×85%)

 

D: cylinder bore (mm)

 

P: working pressure (kgf/cm2)

 

Example: What is the theoretical output force of a cylinder with a diameter of 340 mm and a working pressure of 3 kgf/cm2? What is the output force?

 

Connect P and D to find the points on F and F', and get: F=2800kgf; F′=2300kgf

 

Select the cylinder bore diameter during engineering design, depending on the pressure used and the theoretical thrust or tension

 

The content introduced above is the calculation formula of the thrust of the cylinder piston rod, and the piston rod thrust can be accurately calculated by this method. However, when selecting a cylinder, we should pay attention to make the output force of the cylinder slightly marginal. Otherwise, the cylinder diameter is small, the output force is not enough, and the cylinder can not work normally; but the cylinder diameter is too large, which not only makes the equipment cumbersome, high cost, but also increases the gas consumption, resulting in waste of energy.
