The working principle of the hydraulic cylinder is: when it comes to its working principle, I will first talk about its five most basic components, 1-cylinder and cylinder head 2-live race and live cold rod 3-sealing device 4-buffering device 5- The work of each cylinder of the exhaust device is almost the same. Take a manual jack as an example of its working principle. The jack is actually the simplest cylinder.

      The simple processing of hydraulic cylinders belongs to the category of deep hole processing, ready-made steel pipes can be used, and heat treatment should be carried out after welding to make the material meet the required mechanical properties. Deep hole processing equipment must be used during processing, and the inner hole can be drew to size on the deep hole grinding machine with a margin for grinding during finishing. Generally, oil tank processing plants do not re-cold-draw steel pipes, and mainly purchase ready-made pipes. If it is a small cylinder, the cylinder head is fixed with tie rods at both ends, and there is no requirement for the hardness of the material, it can be directly processed and ground with steel pipe. Under the condition that the wall thickness and strength of the hydraulic cylinder are sufficient, choose seamless steel pipes of appropriate size, preferably those on the bill of materials. Generally, the outer diameter does not need to be processed again.
