Why do the cylinder force enough? The choice of source

Cylinder is not enough force, for the cylinder this failure, what is the reason? How to solve? In addition to this, what problem of cylinder, we also should know and master? Above all these, are below small make up will be illustrated and discussed, so the next time, before it's to embark on it at once. Cylinder is not enough, it's a fault, its concrete reason and solution, it is mainly for: ( 1) The cylinder diameter is too small, not enough output power cylinder, thus it can't work normally. At this time, should be to choose suitable again. ( 2) In the cylinder piston and piston rod stuck, or poor lubrication, lack of supplies. At this time, the response to the axis of the piston rod adjustment, has become clear in time, to fully good lubrication. ( 3) With condensed water or impurities in cylinder, then they should be clean, and to prevent again. Problem: a cylinder only provide air, how should choose? A: provide source for cylinder, usually is the use of air compressor, a power source. There is only one cylinder, then gas will not very big, so the choice of small power air compressor.
