Riveting machine hydraulic system analysis: selection hydraulic circuit. In the work cycle the inner diameter of the hydraulic system to Riveting, hydraulic cylinders alternately require oil source to provide low-pressure high oil flow and high pressure low flow. Improving system efficiency, energy saving point of view, should adopt the double-pump oil supply system, or the use of limited pressure-type variable speed pump plus Yan Volume Throttling Speed ??Control System consisting of radial Riveting plant, but the caulking system Riveting radial velocity is not price, so choose the former is more appropriate. Riveting definition: rivet connection structure applications. Currently due to advances in welding technology and is widely used as well as the development of high strength, riveted structure dwindling. However, since the riveting generally have good toughness and ductility, transfer uniform radial Riveting reliable company, as well as easy to check the quality and maintenance features, so some of the heavy and often subjected to severe shock or severe vibration loads of steel or welding technology limited situations, such as cranes architecture, railway bridges, construction, shipbuilding, heavy machinery and other aspects still riveting.
