Boiler feed pump working principle

The boiler feed pump has many kinds in different situation, the hydraulic system has: the gear, the blade, the plunger and so on the form to carry on the compression. Pumps are: axial flow, mixed flow and other forms. The operating principle of the pressure difference between the inlet and outlet is caused by the rotation.
Boiler feed water pump: conveying reaction, absorption, separation, absorption liquid regeneration of circulating liquid pump. Single stage centrifugal pump. Boiler feed pump flow of medium size, stable operating conditions, the pump flow rate change is relatively small.
The pump is composed of a water inlet and outlet section, a pump head, a flow passage cavity component and a pressure resistant cylinder, and is fixed by a pull rod between the water inlet section and the pump head. Import and export of the pump on the same level of the pump inlet and outlet, and the same diameter, to facilitate the installation of the site.
