Conversionmethod for pressure and tonnage of master cylinder

1.P (physical pressure)=F (force)/S (action area)

2.e.g.: Rated pressure: 40MPa

3.Static pressure mode: (radius of piston: 80mm, radius of piston rod: 40mm,rated pressure: 40MPa)

a. F (push-rodless cavity)                =3.14*R*R*P

                                                    =3.14*80*80*40

                                                  =803840N(804KN) (single cylinder)

Doublecylinder force: 804*2=1608KN

Tonnage:1068KN*0.102=164t

b. F (pull-rod cavity)                      =3.14* (R*R-r*r)*P

                                                    =3.14**(80*80-40*40)*40

                                                    =602880N(603KN) (single cylinder)

Doublecylinder force: 603*2=1206KN

Tonnage:1206KN*0.102=123t

4.Twist drill mode: (radius of piston: 62.5mm, radius of piston rod: 32.5mm,rated pressure: 40MPa)

a. F (push-rodless cavity)                =3.14*R*R*P

                                                    =3.14*62.50*62.5*40

                                                    =490625N(491KN) (single cylinder)

Doublecylinder force: 491*2=982KN

Tonnage:982KN*0.102=100t

b. F (pull-rod cavity)                      =3.14* (R*R-r*r)*P

                                          =3.14*(62.5*62.5-32.5*32.5)*40

                                          =357960N(358KN) (single cylinder)

Doublecylinder force: 358*2=716KN

Tonnage:716KN*0.102=73t
