Marine Accessories Using Performance
Aug 09, 2017

In all kinds of ships, in order to ensure their navigational performance and performance, a large number of mechanical and electrical equipment is needed to meet a wide variety of needs. Marine Accessories In the marine machinery and equipment, the pump is a large number, variety and important role of mechanical equipment. Usually, we refer to the pumps used on ships as well as the port-shore pumps serving ships collectively as marine pumps.

In order to ensure the ship's normal navigation or mooring, to meet the needs of the crew and passengers, to ensure the stability of the ship, resistance to sinking, Marine Accessories residential, security, vitality and the completion of some special mission, and so on, there must be a certain number of, can play a corresponding role in the marine pump. These pumps are not only installed in the ship's power plant, Marine Accessories cargo handling, life service security and other special systems, but also fitted in some marine auxiliary devices. Statistics

In a variety of marine auxiliary machinery and equipment, the total number of marine pumps of various types and uses accounted for about 20% ~ 30% of the total amount of marine machinery and equipment. The total power consumed by the marine pump is about 5% ~ 15% of the total energy consumption of the whole ship, depending on the performance, function and configuration of the ship. In addition, Marine Accessories the price of marine pumps in the cost of shipping equipment accounted for a relatively large proportion. In total cost, the marine pump accounted for about 4% ~ 8% of the cost of the whole ship equipment. Under normal circumstances, Marine Accessories a of ships with more than medium-sized vessels to purchase more than 10 million yuan of the pump. Of course, military vessels and special vessels are not part of the statistics.

Due to the unique independence of the ship and its ability of navigation, Marine Accessories carrying capacity, working performance, safety and dimension weight, Marine Accessories it is necessary to put forward some special technical requirements for marine pumps which are different from other use pumps and land pumps. Marine Accessories These special requirements are usually referred to as marine conditions.

It is precisely because of these conditions that the marine pump has a certain degree of particularity in parameter selection, structure design, manufacture, material selection, Marine Accessories test method, acceptance standard and use condition. If the main points of the embodiment, Marine Accessories can be broadly summed up as follows:

(1) Reliable running performance, no cavitation damage problem.

(2) Low operating vibration and good vibration resistance.

(3) Minimum mechanical noise and liquid noise.

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

(5) Ensure normal operation under tilt and sway conditions.

(6) have sufficient impact resistance ability.

(7) Good corrosion resistance and wear-resisting property.

(8) reliable sealing structure and sealing performance.

(9) Easy disassembly without special tools.

(10) high degree of generalization and so on.

The development of shipbuilding industry is a microcosm of national economic development and the improvement of national science and technology level. With the development of shipbuilding industry in our country, the marine pump in our country has been continuously developing, improving and perfecting both in scientific research, design, production and technological level. In addition to the full absorption and use of other pump industry design experience, Marine Accessories production technology and scientific research, Marine Accessories but also because of marine pump conditions for more than 40 years of uninterrupted scientific research work and the results achieved in the design and production practice of successful application and promotion.
