Volume Booster Mounting Assembly for Vibration-Stable Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional volume boosters in fluid flow control systems are susceptible to flow-induced vibration, leading to instability, noise, and vibration-induced failures, especially in high-capacity applications where multiple boosters and large diameter tubing are required, which destabilizes the mounting system and affects the accuracy and longevity of the actuator assembly.
Innovation Solution
The actuator assembly incorporates a volume booster with a cube-shaped mounting arrangement and a mounting plate that includes slotted holes for secure attachment to the actuator, along with elastomeric rings and vent openings to dampen vibrations, reducing the coupling moment and stabilizing the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional volume boosters are used in high-capacity applications, then flow capacity is improved, but vibration-induced instability and noise increase
Solution Approach 1:
A mounting plate is introduced as an intermediary component between the volume booster and actuator. This mounting plate provides a stable, rigid connection that reduces vibration-induced instability while maintaining the high flow capacity of the volume booster. The mounting plate acts as a mediator that isolates the vibration from the actuator mounting structure.
2Productivity
If multiple volume boosters and large diameter tubing are used to maintain high Cv, then flow capacity is improved, but the mounting system becomes susceptible to vibration induced failures
Solution Approach 1:
The mounting plate converts the harmful vibration energy into beneficial structural stability. By providing a rigid, distributed mounting structure, the vibration forces are dissipated through the plate rather than concentrating on single attachment points, thereby preventing vibration-induced failures while maintaining high flow capacity through multiple boosters and large diameter tubing.
3Ease of manufacture
If conventional pipe components and mounting brackets are used, then assembly is simplified, but vibration induced failures increase due to long tubing runs and cyclic stresses
Solution Approach 1:
The mounting plate combines multiple mounting functions into a single integrated component. Instead of using separate pipe components and mounting brackets that create long tubing runs, the mounting plate provides multiple mounting surfaces and attachment points in one piece, reducing the overall mounting structure complexity and eliminating vibration-induced failures from conventional bracketing systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration significantly reduces vibration-induced failures, enhances stability, and minimizes noise, ensuring accurate and reliable operation of high-capacity fluid flow control systems by effectively coupling the volume booster to the actuator with reduced tubing length and minimized bending, thereby reducing cyclic stresses.
Implementation Method 1
elastomeric rings and vent openings to dampen vibrations, reducing the coupling moment and stabilizing the system
Implementation Method 2
A large, sudden change in the input signal causes a pressure differential to exist between the input signal and the output of the booster. When this occurs, the booster diaphragm moves to open either a supply port or an exhaust port, whichever action is required to reduce the pressure differential.

AI summary
A fluid flow control device includes a body having an inlet connection, an outlet connection, and a discharge port. A supply path extends between the inlet connection and the outlet connection and a booster module is disposed within the body. The booster module includes a control element and an actuator element and defines an exhaust path extending between the outlet connection and the discharge port. A supply port is disposed within the booster module along the supply path between the inlet connection and the outlet connection and at least a first damping means operatively connected to the booster module.
