Application of single piston rod in hydraulic cylinder

The single piston rod in the hydraulic cylinder basically protrudes from one end, so the effective effect of the hydraulic cylinder in the two cavities of the entire piston is not equal in area. If the oil is supplied, and the tears and pressure do not change, the speed or thrust of the piston rod in the two directions is actually not equal, so it has a relatively symmetrical performance in motion. . When the two cavities in the single-piston rod hydraulic cylinder enter the pressure oil at the same time, because the effective area of the rod cavity is larger than the effective area of the rod cavity, the piston rod is pushed to the right In terms of the effect, it must be greater than the force to the left. Then, when the piston moves to the right, the piston rod will actually stretch out, and at the same time, the oil in the rod cavity will be completely squeezed out. , so that it can flow into the rodless chamber, thus effectively increasing the speed of the piston rod as a whole on extension. We can call this connection method of the single piston rod a differential connection.
When performing differential connection, the effective area of the hydraulic cylinder is the size of the entire cross-sectional area of the piston rod, which is similar to the non-differential connection rodless cavity in terms of oil inlet. The connection is actually a way to quickly and effectively realize the movement without increasing the power or capacity of the hydraulic pump, but in actual use, the hydraulic transmission system is basically controlled by The valve is used to change the oil circuit connection of the single piston rod in the hydraulic cylinder, so that it can have different working methods and effectively obtain different cycle effects of work. If the input oil and flow rate are constant, then If the speed at which the piston rod is fully extended is greater, its thrust will be smaller.
