Solving ID Fan Connecting Rod GU23232-12 Fracture: A Highly Efficient Way to End Vibration Exceeding Standard.

Did your 600MW unit's Induced Draft (ID) fan suddenly jump to 200 mm/s or more? That often points right at a snapped ID Fan Connecting Rod, specifically the critical GU23232-12 piece. Hydraulic system spikes—that's the usual killer.

Remember that Datang plant incident? Their rod fractured under massive "squeeze-pull" stress right after a hydraulic pump trip and system repressurization. Vibration went through the roof, way past the safety limit (JB/T9621-1999). The fix? A high-strength replacement: the Dongfang SRI ID Fan Hydraulic Cylinder Connecting Rod GU23232-12.

Here's why the fracture happens, why the vibration explodes, and the real-world solution.

1. Fracture to Catastrophe: How Rod GU23232-12 Failure Starts the Crisis

The GU23232-12 rod is key; it pushes and pulls the movable fan blades. When it breaks, the fan loses all control and goes wildly unbalanced.

2. The Core Truth: The Fracture Is the Vibration

Engineers must see this as a total system collapse, not just a little broken part. Two major dynamics are immediately wrecked:

• A. Force Control Dies = Balance System Gone: The GU23232-12 rod fights the blade's huge centrifugal force with controlled hydraulic force. Fracture stops this fight instantly. The dynamic balance is smashed, leaving the rotor unprotected against two massive, uncontrolled forces (air and spin).
• B. Secondary Damage Spiral: That initial huge vibration immediately trashes precision parts next door—like the slide block (HU25244-12G) or the blade seals (HU25242-22G). This secondary seizing, oil leak, or blade wobble makes the vibration worse, creating a failure loop that accelerates total breakdown: Break -> High Shake -> More Faults.

3. The Only Solution: High-Strength Rod and the Full Protection Kit

You need a component built to take massive, repeated stress, and a system-level stability plan.

① The High-Strength Replacement: ID Fan Connecting Rod GU23232-12

• Toughness: Forged alloy steel, passed through rigorous hardening (quenching, tempering) and non-destructive testing. It simply resists alternating fatigue stress better.
• Result: The blade opening deviation gets fixed fast. Aerodynamic balance returns. Stability restored.

② Coordinated Protection for GU23232-12 Life

A new rod needs a stable environment. Dongfang SRI recommends these coordinated parts to reinforce the whole hydraulic/blade system:

For a tough, high-tensile replacement that meets the highest power plant standards, the Dongfang SRI ID Fan Hydraulic Cylinder Connecting Rod GU23232-12 is your definite answer to stable, compliant fan operation.
