Cylinder is a mechanical engineering major parts, the traditional processing methods are: Broaching cylinder - fine boring cylinder - grinding cylinder. Using rolling method is: Broaching cylinder - fine boring cylinder - rolling cylinder, 3 part process is single-acting cylinders, but the contrast in time: grinding cylinder about 1 m in 1-2 days , rolling cylinder about 1 m in 10-30 minutes. Investment comparison: quilting grinder or mill (tens of thousands - millions), rolling knife (a thousand - tens of thousands). After rolling, the surface roughness of the hole by rolling before Ra3.2 ~ 6.3um buildings reduced to Ra0.4 ~ 0.8 & surface hardness um, hole by about 30%, the cylinder surface fatigue strength by 25%. If only consider the cylinder cylinder life impact, increased by 2 to 3 times rolling process is relatively boring grinding efficiency is about 3 times. The above data shows that the rolling process is efficient engineering cylinders, can greatly improve the surface quality of the cylinder. Products Ultra-thin (flat) jack (Zhu plug), flat (thin) hydraulic jack through high pressure hose, dispensing valve connection, can achieve a hydraulic pump driven by multiple synchronous thin jack up top. Li Lu teach you the knowledge due to the maintenance of the hydraulic cylinder hydraulic pressure to accept a large load heavier its pressure will be greater, and therefore, do maintenance work on the hydraulic cylinder is maintenance of the entire hydraulic system, the most important one ring. Hydraulic cylinder hydraulic system is equivalent to the heart, heart problems difficult to repair, so that the hydraulic cylinder is to maintain detailed careful. First and foremost, to rust. Because part of the hydraulic cylinder piston in the job situation is going to extend the cylinder, would have been a natural oxide, acid gas corrosion, which demands we give it the right grease coating for maintenance, avoiding as load-bearing parts Pistons by corrosion in the job might attack Duanzhe. Secondly, we must change the oil out of the box. Due to prolonged use, inevitably there will be foreign matter from entering the hydraulic cylinder, so that the onset of the conflict in the use will increase the representation, in addition, hydraulic oil also have a certain number of use-life, perhaps for a long time do not change the oil will damage the hydraulic cylinder corrosion interior. Prevention is better governance, and thus in the hydraulic cylinder operation speed to be controlled properly, do not exceed 2m / s, so the use of the hydraulic cylinder can extend life expectancy, and other organizations in order to safeguard and security reasons, the internal buffer device on hydraulic equipment maintenance is very useful.
