Embodiment
1st, during oil cylinder 9 rapid decrease, the rodless cavity oil return of oil cylinder 9, rod chamber oil-feed, because oil inlet and oil return area is than 1:2, return
Oily flow is larger, and because o type three position four-way electromagnetic valve 5 maximum stream flow limits, oil cylinder 9 oil back chamber forms local back pressure, and flow is got over
Greatly, back pressure is higher, and now partial discharge passes through the second counterbalance valve 12 off-load.
2nd, during oil cylinder 9 descending at slow speed, return flow is less, and folding mould valve chock pressure difference is less, the back of the body that now oil cylinder 9 is formed
Pressure is less, and now the second counterbalance valve 12 is not opened, and the first counterbalance valve 2 oil sump tank is passed through in oil return.
3rd, during the rodless cavity oil return of oil cylinder 9, quick descending at slow speed respectively by the first counterbalance valve 2 and the second counterbalance valve 12 this two
Individual counterbalance valve controls, and the second counterbalance valve 12 sets pressure and is consistently higher than the first counterbalance valve 2.
4th, oil cylinder 9 is controlled it by multiple back pressure when declining, and decreases the volume shock and vibration of oil cylinder 9, increases
The stationarity of motion.
5th, the application of multiple back pressure, the latus rectum that can suitably reduce o type three position four-way electromagnetic valve 5 requires, reduces cost.
