Eat water, all know that what does a water pump do. The pump is conveying liquid or causes the liquid turbo-charged machinery. It transmits the mechanical energy or other external energy transmitted to the liquid, causes the liquid energy increase, mainly used for conveying liquid, including water, oil, the sour lye, the emulsion, hangs the emulsion and the liquid metal and so on, also may transport the liquid, the mixture of gases as well as contains the suspended solid liquid. Pump use in our lives is very wide, of course It also depends on the pump performance is good. Generally speaking, if you want to know what does a water pump do, all need to know the pump performance. The technical parameters of the pump performance capacity, suction, head, shaft power, water power, efficiency, etc.; According to the different working principle can be divided into volume pump, vane pump type, etc. Positive displacement pump is to use the studio volume changes to deliver energy; Vane pump is the use of rotary vane interaction with water to deliver energy, such as centrifugal pump, axial flow and mixed flow pump type.
In the shipbuilding, oil, mining, heavy machine, etc, are widely used. Ship output reached 15000 tons, 2008 deadweight tonnage amount accounted for 21% of the world market, by 2015 will become the world's shipbuilding powers. In order to ensure the normal order of the ship sailing and mooring, meet the needs of the crew and passengers of life, every ship should be equipped with a certain number of, corresponding to the function of Marine pump, Marine pump is one of the important auxiliary machinery. According to incomplete statistics, in all kinds of auxiliary machinery equipment, various types and different USES of the total number of Marine pump, accounts for about 20% to 30% of the total ship machinery and equipment, the value of Marine pumps in Marine equipment costs of a fairly large proportion of. In the total cost, Marine pumps about 4% of equipment costs - 4%, in general, more than a medium-sized ship Marine pump purchase of up to 10 million yuan of above. When it comes to key pump market, said countries had completed "west to east gas pipeline project", "west to east gas pipeline project" in the same need to pump products. This is in practice to illustrate what does a water pump do.
