Product-Coal mill vibration isolation-Beijing Huadian Tianheng Technology Development Co.,Ltd.

In the thermal power plant coal grinding machine belonging to a large auxiliary equipment, the operation will produce very big vibration, and thus may influence the power plant auxiliary equipment normal operation, and even leads to thermal power plant accident. Usually subjected to vibration effect of coal mill near the electrical equipment, control room and boiler island near the other equipment. In order to have a reliable control for coal pulverizer vibration transmission, coal pulverizer basis using the spring vibration system in thermal power plant, which has been widely used, and the need to occupy much space compared to conventional basis, the use of spring vibration isolation system, coal pulverizer basis needed much smaller space.

Mill spring vibration isolation system is through the vibration isolator springs and viscous dampers to achieve. Spring vibration isolator with high quality durable cylindrical helical compression springs, viscous damper is proportional to speed the damping effect, and the spring vibration isolator used in parallel. Mill spring vibration isolation system can reduce coal pulverizer basis weight and reduce vibration transmission.

Beijing Heng technology development limited development of the coal grinding machine spring vibration isolation system the main advantages are : the use of spring vibration isolation system, coal mill base pedestal volume or weight only about half of the conventional foundation block. The mill base seat and boiler plant structure isolation, coal pulverizer basis construction is relatively independent, and there are a lot of flexibility, can shorten the coal pulverizer basis construction time. By the spring vibration isolation system can also simplify the coal grinding machine leveling, the foundation settlement through the spring vibration isolator is leveling. From the process layout can also reduce associated with various pipelines and cables amount, increase the mill auxiliary equipment and pipelines can be arranged in space.

By the spring vibration isolation system, there will be no obvious vibration to the boiler and the building, also reduces the coal grinding machine vibration, reducing mill on the surrounding buildings and staff vibration effect. Caused by the vibration of the boiler and boiler lining damage and repair caused due to thermal power plant accident can be avoided.
