practical application
Widely used in shipbuilding, oil extraction, and heavy-duty machinery. In 2008, the ship production reached 15000 tons, accounting for 21% of the world market in terms of deadweight tonnage. By 2015, it will become the world's largest shipbuilding country. In order to ensure the normal navigation or mooring of the ship and meet the living needs of the crew and passengers, each ship must be equipped with a certain number of ship pumps that can play a corresponding role. Ship pumps are one of the important auxiliary engines. According to incomplete statistics, the total number of various types and purposes of marine pumps in various marine auxiliary machinery equipment accounts for about 20% -30% of the total amount of marine machinery equipment, and the price of marine pumps also accounts for a relatively large proportion of the cost of marine equipment. In the total cost, marine pumps account for about 4% -8% of the equipment cost. Generally, the purchase of marine pumps for a medium-sized or larger vessel can reach more than 10 million yuan. When it comes to the key pump market, we cannot ignore the completed "West East Gas Pipeline" project in China, which also requires pump products. At the same time, the country also needs to build other natural gas pipelines, which require a large amount of pump products.
Different uses
Water pumps have different purposes, conveying different liquid media, different flow rates, and different head ranges. Therefore, their structural forms and materials are also different. In summary, they can be roughly divided into:
1. Urban water supply 2, sewage system 3, civil and building systems 4, agricultural water conservancy system 5, power station system
6. Chemical system 7, petroleum industry system 8, mining and metallurgical system 9, light industry system 10, ship system
