I designed the steam feed pump spring vibration isolation foundation has safe operation for many years. Steam feed pump belongs to a rotary machine, the spring vibration isolation foundation and design principle of the steam turbine generator, coal mill and crusher, rotary machine based design principle is the same. In view of steam feed pump speed is higher, generally with the vibration velocity as a control design of the main technical indicators. Our company mainly technical staff to fully grasp the turbine-driven feedwater pump fundamental design principles. Our own design of the first mill spring vibration isolation foundation is provided by my company technical staff to complete; the first steel ball coal grinding machine spring vibration isolation foundation is also from my company technical staff to complete; the first medium speed coal grinding machine spring vibration isolation foundation is also from my company technical staff completed. My company's design and manufacturing capacity in the spring vibration field is the leading domestic level.
