Marine Accessories Performance And Performance
Jul 01, 2017

In a variety of ships, Marine Accessories in order to ensure its navigation performance and performance, are required to meet a wide range of different needs of mechanical equipment and electrical equipment. In the ship machinery and equipment, the pump is a large number, Marine Accessories variety and role of important mechanical equipment. Marine Accessories Often, we refer to the pumps used on ships and the port pumps serving the ship as a marine pump.

In order to ensure the normal sailing or mooring of the ship, Marine Accessories to meet the needs of the crew and passengers, to ensure the stability of the ship, Marine Accessories anti-sink, living, security, vitality and the completion of certain special missions, need to have a certain number, The corresponding role of the marine pump. These pumps are not only installed in the ship's power plant, Marine Accessories cargo handling, life service safety and other special systems, but also in some of the ship auxiliary device. Marine Accessories According to incomplete statistics.

In a variety of ship auxiliary machinery and equipment, Marine Accessories the total number of various types and different uses of marine pumps, accounting for about 20% to 30% of the total ship machinery and equipment. The total power consumed by the marine pump is about 5% to 15% of the total energy consumption of the ship, depending on the ship's performance, function and equipment configuration. In addition, Marine Accessories the price of marine pumps in the cost of ship equipment, the proportion is relatively large. Marine Accessories In the total cost, the marine pump accounts for about 4% to 8% of the cost of the whole ship. Under normal circumstances, a medium-sized ship of marine pump procurement up to 10 million yuan. Of course, military ships and special ships do not belong to the statistics.

Due to the unique independence of the ship and its reasons in navigational capacity, carrying capacity, work performance, safety performance and size and weight requirements, it is necessary to propose some special technical requirements for marine pumps other than other pumps and land pumps. These special requirements are usually referred to as marine conditions.

It is because of these marine conditions, making the marine pump in the parameter selection, structural design, manufacturing, material selection, Marine Accessories test methods and acceptance criteria and the use of conditions such as a certain degree of particularity. If the main points of which the specific, Marine Accessories can be roughly summarized as the following main aspects:

(1) reliable operating performance, no cavitation damage problem.

(2) lower operating vibration and good vibration resistance.

(3) the smallest mechanical noise and liquid noise.

(4) small size, light weight, occupy a smaller space.

(5) to ensure normal operation in the case of tilt and swing.

(6) has sufficient impact resistance.

(7) good corrosion resistance and abrasion resistance.

(8) Reliable sealing structure and sealing performance.

(9) easy disassembly and no special tools.

(10) high degree of generalization and so on.
