AI Technical Summary
When the cantilever impeller rotates at high speed, it is prone to loosening due to vibration, which can cause the nut to come loose, leading to impeller movement and equipment accidents. Existing anti-loosening measures have problems such as large space occupation, poor high temperature resistance, or difficulty in disassembly.
By combining rigid mechanical locking with fluid dynamics, a dual anti-loosening mechanism is formed through the design of anti-rotation pins and anti-rotation washers. Fluid energy is used to generate a tightening torque, which, combined with rigid mechanical locking, achieves anti-loosening.
It achieves reliable anti-loosening effect throughout the entire cycle under high-frequency vibration and frequent start-stop conditions. It has a compact structure, is easy to maintain, reduces maintenance costs, and avoids equipment accidents caused by loose nuts.
