A hydraulic cylinder is an executive unit by outputting directly proportional linear motion of force and effective area of piston and pressure difference added to its two ends, functioning as an energy transformer from hydraulic to mechanic. To understand it, let’s talk about it on view of installing and running of a hydraulic cylinder structure as below.
Before installation, the plug for gasified antirust agent sealed in the cylinder placed at the inlet has to be taken down. Once unplugged, the cylinder must be equipped on to the host and fulfilled with hydraulic fluid. Then, if the piston is laid stretching out, grease must be coated on the stretching part.
For a common model, when the speed of stroke exceeds 2m/s, the spanlife of a cylinder will be affected while a buffering organ is advised for purpose of protection and safety under the situation of 0.3m/s for the stroke end. Besides, also for such a purpose, prevention of heavy impact on the stroke route should be considered when a stroke stops. To increase return flow of oil, the factor of kinetic, especially, shock caused by a low motion of under 0.5m/min should be paid particular attention to when designing the route. So, when under a low speed, the situation should be another matter to talk about.
