S-ULP-V steel spring (viscous damping) vibration isolator S-ULPV-2011.../47的优势 +
Spring elements are effectively used for mechanical vibration isolation in power plants. Turbine worktable, feedwater pump, etc. They provide support for static loads and reduce the transmission of dynamic loads to the foundation. Spring components typically consist of three main parts: upper and lower shells, spiral coil springs, and viscoelastic dampers. The system frequency is usually between 2-7 Hz.The basic design of the spring element consists of a set of spiral coil steel compression springs connected to the top and bottom plates. In general, due to the natural material damping of steel components, the damping performance of spring elements is very low. As long as higher damping characteristics are required, viscoelastic damping elements can be integrated into spring elements. An important feature of spring elements is their ability to lock them at a predetermined compression level (preload). Pre installed spring elements are installed in the locked position to serve as solid supports. At the end of installation - possibly heavy machinery - the spring elements are activated: they are unlocked. From that moment on, the device acted as a vibration control component. -
S-ULP-V steel spring (viscous damping) vibration isolator S-ULPV-2011.../47的性能 +
This product portfolio covers most typical applications of basic isolation in power plants and installation of condensers. By combining a set of spring elements in one application, optimal settings can be achieved. The spring element is independent of the additional damping element. Without damping, the load covered by the component ranges from 126kN to 2096kN, with a damping load of up to 1300kN. -
