Project Overview

Existing systems suffered from inefficient capture, leading to air quality degradation and potential fire hazards[cite: 3, 5]. Previous ductwork lacked proper fluid dynamic balancing[cite: 6]. We implemented an engineered solution for Machine 01 focusing on static pressure and capture velocity[cite: 8].

Identified Risks

• Health Hazards: Chronic respiratory issues for operators[cite: 59].
• Fire & Explosion: Combustible dust accumulation in enclosed spaces[cite: 60].
• Equipment Wear: Abrasive dust damaging bearings and electronics[cite: 61].

Concept 1: Capture Velocity

Capture velocity is the air speed required at the hood to "grab" dust particles before they escape[cite: 23]. Proper hood design maximizes velocity by minimizing the opening area[cite: 24].

Concept 2: Flow Rate Balance

The core engineering relationship used for balancing the system[cite: 26]:

Q: Flow Rate | V: Capture Velocity | A: Opening Area

Concept 3: Bernoulli’s Principle

Total mechanical energy in a flowing fluid remains constant[cite: 36]. In industrial ductwork, we must manage the conversion between static and velocity pressure[cite: 36].

Concept 4: TP = SP + VP

Total Pressure ($TP$) is the sum of Static ($SP$) and Velocity ($VP$) Pressure[cite: 37]. Reducing $SP$ losses through smooth transitions allows for higher $VP$[cite: 40].

Reducing Static Loss

Legacy systems fail due to high friction caused by sharp bends[cite: 39]. Our new design uses optimized geometry to ensure laminar flow and minimize turbulence[cite: 40].

Advanced Duct Components

• Spiral Seam Piping: Stronger structural integrity for suction[cite: 45, 48].
• Long Radius Elbows: Reduces turbulence and friction loss[cite: 44, 47].

Balanced Fan Performance

Motors and fans are sized perfectly for the required CFM[cite: 49]. This eliminates unnecessary vibration and ensures consistent suction at every machine port[cite: 46].

Machine 01 Redesign

• Complete duct line redesign for optimal airflow[cite: 13].
• Precision angle adjustments to minimize friction[cite: 14].
• Verified suction efficiency across all ports[cite: 16].

Efficiency Outcomes

The Geometry Advantage

The data proves that by simply correcting ductwork geometry, we achieve nearly perfect capture without replacing expensive collector units.
