Axial flow pump

Posted by Wangkiky Wangkiky over 6 months ago

The impeller of an axial flow pump is equipped with 2 to 7 blades and rotates in a round tubular pump shell. Fixed guide vanes are installed on the upper pump housing of the impeller to eliminate the rotational motion of the liquid, to make it move axially, and to transform the kinetic energy of the rotational motion into the pressure energy. Axial flow pump is usually single-stage type, a few are made into two-stage type.

Axial flow pump is generally vertical, impeller submerged under water, there are horizontal or oblique axial flow pump. When the impeller of small-sized axial flow pump is installed above the water surface, it needs to start with vacuum pump exhaust and water diversion. The blades of the axial flow pump are divided into fixed and adjustable structures. The operating conditions of large-scale axial flow pumps (mainly refers to the flow rate) often need to be changed greatly in operation. Adjusting the installation angle of blades can keep the pumps running in high efficiency areas under different operating conditions.[url=https://www.vacuumpumpworks.com/pump-online/281.html]Hot Sales Double Suction Centrifugal Water Pump[/url] The blade mounting angle of small pump is usually fixed. Axial flow pump is one of the highest specific speeds in power pumps, with specific speeds ranging from 500 to 1600. The flow-head and flow-axis power characteristic curve of the pump is steep in the small flow area, so it should be avoided to operate in this unstable small flow area. Axial flow pump has the maximum axial power at zero flow rate, so the valve in discharge pipeline must be opened before starting to reduce the starting power. Axial flow pumps are mainly used in low head and large flow situations, such as irrigation, drainage, dock drainage, water level regulation of canal lock, or as large circulating water pumps in power plants. Axial flow pumps with high lift (made into two stages if necessary) can be used for water jet propulsion of shallow water vessels.[url=https://www.vacuumpumpworks.com/pump-work/2234.html]Quattro Cooling System Auxiliary Water Pump[/url]
