12420483 Air Intake Bellows DEUTZ MWM TBG620 V16 Gas Generator Set

1. Basic Application Information

2. Operating Condition Boundaries for TBG620 V16 (6002) Unit

3. Precise Dimensional & Structural Parameters (Finalized by Actual Unit Installation Measurement)

4. Material & Condition Resistance Performance (Custom EPDM Formula for Gas Units)

4.1 Layered Structure

• Inner layer: Condensed water resistant EPDM for gas service; resists swelling from trace natural gas components and prevents debris shedding that may damage turbocharger impellers
• Middle layer: Double-layer high-tenacity polyester braided reinforcement layer; prevents inward collapse under negative pressure
• Outer layer: Ozone and high-temperature aging resistant EPDM; avoids cracking from long-term continuous operation of generator sets

4.2 Temperature Resistance

• Continuous operating temperature range: -40°C ~ +125°C
• Instantaneous thermal shock limit: 135°C, no delamination or bulging after 15 minutes of exposure

4.3 Pressure Performance (Matched with Negative Pressure of TBG620 V16 Unit)

• At rated negative pressure of -88 kPa: No pipe wall indentation, cross-sectional flow area reduction ＜3%
• Positive withstand pressure: 0.35 MPa, no delamination or bulging
• Burst safety pressure: ≥1.1 MPa
• Connector pull-out resistance: ≥950 N; resistant to loosening under alternating tension during unit startup and shutdown

5. Core Functions for TBG620 V16 Unit

Vibration Isolation

Large-Flow Intake Flow Guidance

Noise Reduction

Condensed Water Diversion

6. Exclusive Installation Specifications for TBG620 V16 (6002) Unit

1. Direct fit at original mounting position; no cutting or rerouting required, free of interference with engine wiring harness and cooling water pipelines;
2. Tightening torque for OEM supporting hose clamps: 6.5～8 N·m; fasten clamps evenly at both ends to avoid flow area reduction caused by one-sided over-compression;
3. Install the hose in natural relaxed state without twisting; maximum allowable twist angle strictly limited to ≤15°;
4. The intake bellows on both turbocharger sides of a single V16 unit share the same part number and are interchangeable left and right.

7. Replacement Criteria Based on Unit-Specific Fault Phenomena

1. Corrugation cracking, outer rubber pulverization or inner layer detachment;
2. Pipe collapse under negative pressure leading to insufficient intake flow, reduced active power output and elevated gas consumption of the unit;
3. Air leakage at connectors causing unbalanced mixture ratio, frequent unit alarms, unstable idling and abnormal exhaust temperature;
4. Hose deformation and dislodgement at hose clamp positions, posing gas leakage safety hazards.

8. Endurance Standards for Continuous Generator Set Operation

• Continuous service life: ≥5 years / 40,000 operating hours
• Reciprocating fatigue test: No corrugation fracture or delamination after 100,000 vibration cycles
• Weathering resistance: No hardening or cracking under long-term exposure to engine compartment oil contamination, ozone and high temperatures
