Selection of ball valve damper in various equipment
In steel plants, power plants, oil plants, cement plants and other industries, there are various types of pipelines and equipment, and they will choose to add some components for maintenance according to the requirements. These industries have a high demand for pipelines, so most of the center uses ball valve dampers. But ball valve damper
There are many varieties, so there is a request for its selection.
1. The outer surface of shell and ball valve shall be treated by baking paint, galvanizing, zinc aluminum and other methods to prevent the vibration isolator from rusting in a short period of time, which will affect the service life of the vibration damper. It is better not to use the products treated by painting;
2. The longitude between the operating frequency of the equipment and the natural frequency of the ball valve damper shall be greater than
3. How to ensure that the vibration isolation efficiency is above 85% under this condition;
4. The stiffness and vertical rigidity of the ball valve shall be greater than or equal to 1, and the ratio between the requested diameter of the ball valve and the height of the ball valve after the rated negative pressure shall be greater than 0.7 to ensure the stability of the degree direction of the ball valve damper;
5. Proper ball valve damper shall be selected as the guide line of the convenient device.
As long as the right ball valve damper is selected, it can play its role more effectively. If the wrong model is selected, it may not only fail to maintain, but may backfire, causing unnecessary damage to pipes or equipment.
