oil spring
1.THIS PRODUCT ADOPTS THE ADVANCED PENG LAI RICE, ADD THE SHRIMPS, OIL SPRING ONIONS AND HAM.
2.A study on the design of throttle chink has been carried out; a simulative analysis on the damping characteristics of all oil-pneumatic springs has been conducted,and finally the laboratory test on characteristics of resistance was performed on the being designed oil-pneumatic spring.
3.ANew Method Determining the Operating Oil Pressure in Radial Spring-Loadedand Axial Disc Brake Systems for Winders
9.Abstract: Counterbalance problem of oil pumping unit is researched in detail,and it is pointed out that counterbalances of matching weight and gas pressure are two main types of counterbalance of oil pumping unit.The possiblity for oil pumping unit to use spring counterbalance or flywheel counterbalance is put forward.
