introduction：Neumans cylinder production plant With the progress of The Times，The industrial sector is also becoming more developed。Neumans cylinder，It is a cylindrical metal part that guides the piston to move in a straight line。The working medium converts thermal energy into mechanical energy through expansion in the engine cylinders；The gas in the compressor cylinder is compressed by the piston and the pressure is increased。 Neumans cylinder manufacturers interpret the working principle： Determine the thrust and pull force on the piston rod according to the size of the force required for the work。Therefore, when selecting the cylinder, the output force of the cylinder should be slightly surplus。If the diameter is too small，underoutput，The cylinder is not working properly；But the bore is too large，Not only make the equipment cumbersome、High cost，At the same time, air consumption increases，Waste energy。In fixture design，Force-boosting mechanisms should be used as far as possible，To reduce the size of the cylinder。 Ameri

introduction：How to install linear guide rail knowledge is introduced，The effect of linear guides is to support and guide moving parts，Reciprocating straight motion in the given direction。It depends on the nature of the conflict，Linear motion guides can be divided into sliding collision guides、Tumbling collision guide、Elastic collision guide、Fluid conflict rails and other varieties。Fluid smoothness on the sliding guide surface，Due to the rise of the oil film，Errors in the accuracy of the motion that occur cannot be prevented。In the vast majority of cases，Fluid smoothness is confined to the chasm region，Direct conflict arising from the touch of metal cannot be prevented，In this conflict，A lot of energy is wasted through conflict loss。
