4TY0090 Fan hydraulic cylinder spring plate

Description of 4TY0090  Fan hydraulic cylinder spring plate

In the dynamic blade adjustment system of large axial flow fans, the spring plate serves as a key elastic element for dynamic blade angle regulation and load transmission. Its performance directly determines the fan’s adjustment accuracy, operational stability, and fatigue resistance. The 4TY0090 Fan hydraulic cylinder spring plate is a high-performance elastic component specifically designed for dynamic blade adjustment in axial flow fans. Through unique structural design, high-quality material selection, and precision manufacturing processes, it achieves precise blade angle control and effective vibration suppression under complex conditions such as high temperature, high speed, and variable loads, becoming an indispensable "flexible joint" in modern axial fan intelligent adjustment systems.

Function of 4TY0090  Fan hydraulic cylinder spring plate

Dynamic blade adjustment axial flow fans are widely used in industries such as power, steel, and petrochemicals. The spring plate functions in two main ways:

1. Elastic Connection and Load Transmission**: As a flexible connector between the blade adjustment mechanism (e.g., hydraulic cylinder, connecting rod) and the blade shaft, the spring plate accurately transmits the adjustment driving force to the blades while absorbing impact loads caused by airflow pulsation and mechanical vibration, avoiding stress concentration and component damage due to rigid connections.

2. Vibration Suppression and Fatigue Buffering: During fan operation, blades are subjected to centrifugal forces (up to tens of kilonewtons) and alternating airflow loads. The spring plate, through its high internal damping characteristics, converts vibration energy into heat, reducing system vibration levels (measured reduction up to 40%), and extending the service life of components such as blade bearings and adjustment linkages.
