The following is the calculation formula of the theoretical output of the supplier of nodular castings. The wholesale of nodular castings:
F: Cylinder theoretical output force (KGF) f ': output force at 85% efficiency (KGF) - - (f' = f × 85%)
D: Cylinder diameter (mm) P: working pressure (kgf / cm2) example: for a cylinder with a diameter of 340mm, when the working pressure is 3kgf / cm2, what is the theoretical output force? What is the output of buds?
Connect P D, find out the points on F f ', get:
F = 2800kgf; f '= 2300kgf in engineering design, the cylinder diameter can be selected according to its service pressure theoretical thrust tension.
Example: there is a cylinder with a service pressure of 5kgf / cm2, its thrust is 132kgf (cylinder efficiency is 85%) when the cylinder is pushed out. How large cylinder diameter should be selected?
The theoretical thrust of the cylinder can be calculated as F = f ' the thrust of the cylinder 132kgf the efficiency of the cylinder 85%
/85% = 155 (kg). According to the applied pressure of 5kgf / cm2 the theoretical thrust of the cylinder, it is found that the selected cylinder diameter is? The cylinder of 63 can meet the use requirements.
