How does water pump work from its work principle

Water pump in the countryside, almost every family has. But professional Angle to define: 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, this is a very simple explanation water pump how it work. Season crops, when water is in short supply of the field, people will choose with a water pump water to meet the needs of the crops. Of course, we are to buy water pump, also need to consider many factors, hope to be able to buy good quality water pump. 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. The below we will with the working principle of pump to explain water pump how it work. 

   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. 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. The technical parameters of pump performance can be measured in flow, 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. 1, positive displacement pump: used to transport liquid cycle working volume change. 2, vane pump, use the blade and liquid interaction to conveying fluid. For these textual theory, however, may not have too much useless, if you want to better know water pump how it work, I think that practice is the most important.
