Marine pump stations are an important part of marine engineering, providing power for the ship’s hydraulic system and supporting other systems of the ship. It consists of key components such as hydraulic pumps, motors, oil tanks and overflow valves. It is made of corrosion-resistant materials and meets the requirements of ship specifications and marine technical conditions.
Main functions and roles of marine pump stations
- Liquid transportation:
Marine pump stations are mainly used to transport various liquids, including seawater, fresh water, sewage, lubricating oil and fuel oil. These liquids play a vital role in the daily operation and maintenance of ships.
For example, seawater can be used for cooling systems, fresh water for drinking and cleaning, and fuel oil is the main source of ship power.
- Hydraulic system drive:
Marine pump stations also include hydraulic pump stations, which are marine hydraulic source devices consisting of hydraulic pumps, motors, oil tanks and overflow valves. It provides power for various hydraulic systems on ships, such as hydraulic drives for steering gear, deck machinery, etc.
- Ship system support:
Marine pump stations support multiple systems of ships, including but not limited to cooling systems, lubrication systems, fire protection systems, ballast systems, etc. The normal operation of these systems is essential for the safety and efficiency of ships.
- Compliance with ship specifications:
The design and manufacture of marine pump stations must comply with the requirements of ship specifications and marine technical conditions. This ensures the compatibility and safety of the pump station with other systems of the ship.
- Structural features:
Marine pump stations generally adopt vertical structures to reduce the occupied area and facilitate maintenance. At the same time, the flow-through components are made of corrosion-resistant materials such as bronze, brass or stainless steel to meet the challenges of the offshore environment.
- Widely used:
Marine pump stations are widely used on modern ships. A diesel-powered cargo ship may need 36 to 50 pumps of various types, and the number of pumps accounts for 20% to 30% of the total amount of ship machinery and equipment.
- Classification and working principle:
There are many types of marine pump stations according to their uses and working principles. For example, according to their uses, they can be divided into pumps for ship power plants, general ship pumps, and special ship pumps; according to their working principles, they can be divided into positive displacement pumps, impeller pumps, and jet pumps.
