The difference between pressure and pressure of vacuum press

2021-06-25 11:40

Pressure of vacuum press: it is the unit of force acting vertically on the surface of an object ~ Newton ~ F = P * S P for short is the pressure
Pressure of vacuum press: it is the unit of force on the unit area of the object ~ Pascal ~ referred to as Pa P = F/S F is the pressure.
This is a set of mechanical knowledge;

How to check and accept the pressure and pressure of the vacuum press? It requires an output pressure of 300 tons and a plunger diameter of 400mm.
Six workpieces with an area of 105*200mm are laid flat on a template with an area of 430*460mm and pressed together. Vacuum compressor: when the set surface pressure value is 10MPa, the output of the oil cylinder is F = 500x 600x 10=300T. However, under the same conditions, we compare the 200-ton vacuum press with it, which is thinner than his pressure.
