The application of pumps on ships

In various types of ships, a large amount of mechanical and electrical equipment is required to meet different needs for their navigation and operational performance. In ship machinery equipment, pumps are a type of mechanical equipment with a large quantity, diverse varieties, and important functions. Usually, we refer to pumps used on ships and shore pumps serving ships as marine pumps. In order to ensure the normal navigation or mooring of the ship, meet the needs of crew and passengers, and ensure the stability, anti sinking, livability, vitality, and completion of certain missions of the ship, there is a need for a quantity of ship pumps that can play a corresponding role. These pumps are not only installed in the power units, cargo handling, life services, and other systems of ships, but also in certain ship auxiliary devices. According to no statistics. In the auxiliary machinery equipment of ships, the total number of ship pumps of different types and purposes accounts for about 20% to 30% of the total amount of ship machinery equipment. The total power consumption of marine pumps, depending on the performance, functionality, and equipment configuration of the vessel, accounts for approximately 5% to 15% of the total energy consumption of the entire ship. In addition, the price of marine pumps also accounts for a relatively large proportion of the cost of ship equipment. In the total cost, marine pumps account for about 4% to 8% of the total equipment cost of the ship. In general, the purchase of ship pumps for a medium-sized or larger vessel can reach over 10 million yuan. Of course, warships and special vessels are not included in the mentioned statistics.
