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 double-acting cylinder, 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 cylinder, 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 and can greatly improve the surface quality of the cylinder. The most basic principle of the first five parts it: the cylinder and cylinder head, piston and piston rod seals, buffer device, exhaust. Each cylinder works are almost similar, take a manual jack, the jack in fact, is the most simple cylinder. By manually pressurized stalk (hydraulic hand pump) hydraulic oil through a one-way valve into the self-locking hydraulic cylinder piston cylinder, then the hydraulic oil into the cylinder valve because of the individual can no longer backwards back, forcing the cylinder rod upward, Then continue to work constantly hydraulic oil into the hydraulic cylinder, and thus constantly on the rise, to fall when he opened hydraulic valves, hydraulic oil tank back light tanks, this is the most simple works, the other is in the based on the improvement of the cylinder with the fuel tank is basically the same principle. Light tanks, Lu Hydraulic (certified), provided by the Texas Lu Hebei cylinder power plant hydraulic equipment. Texas Lu force hydraulic machinery plant (www.luliyeya.com) is a leader in Dezhou, hydraulic machinery and parts, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Lu Hydraulic leadership with the staff warmly welcome all inquiries negotiations to create Lu hydraulic force a better future.
