Overview

This document provides a detailed reference list of auxiliary blowers produced by Nyborg AS, primarily used in marine engine applications. It includes blower types, parameters, electric motor specifications, and corresponding ship engine types.

Main Sections

1. Blower Identification and Specifications

The document lists various blower models identified by codes such as 8L35MC, 6L35MC, 7L45GBE, etc. Each blower entry includes:

• Blower type and model number
• Associated electric motor type (e.g., mSSKg180M-2, m2SKg250M-2)
• Power rating in kilowatts (kW), ranging from approximately 13.5 kW to 96 kW
• Rotational speed in revolutions per minute (r.p.m.), typically between 2,920 and 3,575 r.p.m.
• Corresponding ship engine type (e.g., DTM-35-1, DM-40-3)

2. Air Flow and Pressure Parameters

Additional data includes airflow rates (in cubic meters per second, m3/s) and pressure values (in Pascals, Pa) for various blower models. These parameters indicate the blower's capacity and operational pressure, essential for matching blower performance to engine requirements. Examples include:

• 2.70 m3/s at 4200 Pa
• 4.50 m3/s at 2500 Pa
• 3.20 m3/s at 5800 Pa
• 8.51 m3/s at 3200 Pa

3. Electric Motor Types and Characteristics

The electric motors driving the blowers are specified with codes indicating design and power characteristics, such as mSSKg180M-2, m2SKg250M-2, and m2SKg200L-2B. These codes reflect motor frame size, power class, and pole configuration, which influence blower performance and compatibility.

4. Application and Usage

The blowers are designed for auxiliary use in marine engines, supporting combustion air supply and ventilation. The document references specific engine models (e.g., DTM-35, DM-40, WPM-50) indicating tailored blower-engine pairings for optimal performance.

Key Data Summary

Critical Information and Recommendations

• Matching blower to engine: It is essential to select the blower model with appropriate airflow and pressure parameters to meet the specific engine's air supply requirements.
• Motor compatibility: Ensure the electric motor type and power rating align with the blower's operational demands and ship's electrical system.
• Speed considerations: The rotational speed must be compatible with both blower design and engine operational parameters to maintain efficiency and reliability.
• Performance parameters: Airflow and pressure values are critical for ensuring adequate combustion air and ventilation; deviations can affect engine performance and emissions.
