Description

обратный клапан 7 лоступает в дополнительный гидроцилнндр 5 при закрытом обратном клапане 8. Плунжер 6 должен иметь наружный днаметр несколько меньше наружного диаметра цилиндрической части заготовки (с учетом сжимаемости жидкости при высоком давлении).non-return valve 7 enters the additional hydraulic cylinder 5 with the non-return valve 8 closed. Plunger 6 should have an outer diameter slightly smaller than the outer diameter of the cylindrical part of the workpiece (taking into account the compressibility of the fluid at high pressure).

Таким образом, дополнительный гидроцилиндр позвол ет компенсировать практически все усилие, действующее на донную часть заготовки со стороны л идкостн.Thus, the additional hydraulic cylinder makes it possible to compensate for almost all the force acting on the bottom part of the workpiece from the side of the unit.
