Practical application
It is widely used in shipbuilding, oil exploitation, truck and so on. In 2008, the ship output reached 15000 tons, and the DWT accounted for 21% of the world market. By 2015, it will become the largest shipbuilding country in the world. In order to ensure the normal navigation or mooring of the ship and meet the living needs of crew and passengers, each ship must be equipped with a certain number of marine pumps that can play a corresponding role. Marine pumps are one of the important auxiliary machines. According to incomplete statistics, among various ship auxiliary mechanical equipment, the total number of marine pumps of various types and different purposes accounts for about 20% – 30% of the total amount of ship mechanical equipment, and the price of marine pumps also accounts for a large proportion in the cost of ship equipment. In the total cost, marine pumps account for about 4% – 8% of the cost of marine equipment. Generally, the purchase of marine pumps for more than one medium-sized ship can reach more than 10 million yuan. When it comes to the key pump market, it is necessary to say that the completed “west to East Gas Transmission” project in China also needs pump products. At the same time, the state will build other natural gas transmission pipelines, and a large number of pump products are also required in these projects.
Different uses
The water pump has different purposes, different conveying liquid media, different flow and different lift ranges. Therefore, its structural form is certainly different and its materials are also different. To sum up, it can be roughly divided into:
1. Urban water supply 2. Sewage system 3. Civil engineering and construction system 4. Agricultural water conservancy system 5. Power station system
6. Chemical system 7, petroleum industry system 8, mining metallurgy system 9, light industry system 10, ship system
