Description

This configuration substantially improves the safety of ship operation while guaranteeing performance. The combination of a marine vertical single-stage pipeline centrifugal pump and an explosion-proof motor ensures reliable, efficient, and safe operation in hazardous marine environments.

1. Role and Advantages of Explosion-Proof Motor

  1. Explosion-proof grade: Designed to ATEX international standards for safe operation in flammable and explosive gas or dust environments.
  2. Safety: Prevents explosion risks from electrical sparking in marine scenarios with flammable gases (methane, hydrogen) or volatile liquids (fuel oil, methanol).
  3. High Reliability: Enhanced sealing, typically IP55 or above, resists humidity and salt spray in ship environments.

2. Marine Vertical Single-Stage Pipeline Centrifugal Pump & Explosion-Proof Motor Combination Features

  1. Pump structure:
    • Vertical design saves space and allows direct pipeline installation.
    • Single-stage impeller for stable flow and head, ideal for short-distance high-efficiency transport.
    • Pipeline inlet and outlet directly connected, reducing resistance loss.
  2. Advantages of explosion-proof motor configuration:
    • Fully enclosed design ensures no leakage during operation.
    • Dynamic and static seals use corrosion-resistant, high-pressure mechanical seals for hazardous media.
    • High-temperature protection system for safe shutdown under abnormal conditions.

3. Scope of Application

  1. Marine applications:
    • Fuel delivery system for diesel, heavy oil, methanol, etc.
    • Fire-fighting system water supply.
    • Conveying dangerous liquids from storage tanks.
    • Cooling circulation systems with combustible coolant.
  2. Industrial and special ships:
    • Chemical carriers for flammable chemicals.
    • Fuel supply ships for methanol and other new fuels.

4. Technical Parameters

  1. Pump body: Cast iron, stainless steel
  2. Impeller: Stainless steel
  3. Seal: Mechanical seal

5. Performance Advantages

  1. High efficiency & energy saving: Optimized motor and pump design reduce energy consumption while maintaining safety.
  2. Environmental adaptability: Anti-corrosion and protective properties for salt spray, humidity, and high temperature.
  3. Convenient installation: Compact vertical design and standardized interfaces enable quick installation and replacement.

6. Maintenance and Upkeep

  1. Motor inspection: Regularly check the explosion-proof motor shell for integrity.
  2. Seal replacement: Inspect for aging or wear and replace seals as needed.
  3. Cooling system maintenance: Ensure cooling channels are clear to prevent overheating.
  4. Bearing lubrication: Add suitable lubricants regularly to minimize friction.
  5. Electrical connection check: Inspect junction box sealing to prevent salt spray or moisture intrusion.
