How to debug the rotary cylinder without rotating in place?

Take the end of the cylinder with piston rod as the top and the end without piston rod as the bottom. Then, to slow down the rising speed of the cylinder, turn down the governor valve of the upper exhaust (don't adjust it from the lower part).

To slow down, turn down the speed regulating valve of the exhaust gas below (don't adjust it above); On the contrary, if you want to go up or down quickly, turn it up. Try not to tune up and down together. Try to adjust some, adjust some more, and immediately adjust to the ideal position and speed.

Main advantages:

The thrust and tension on the piston rod are determined according to the force required for the work. Therefore, when selecting the cylinder, the output force of the cylinder should be slightly to the left. If the cylinder diameter is small and the output force is not enough, the cylinder cannot work normally; However, the cylinder diameter is too large, which not only makes the equipment cumbersome and costly, but also increases gas consumption and causes energy waste. When designing the fixture, the booster should be used as much as possible to reduce the size of the cylinder.
