Knowledge for domestic production of screw pumps for steam turbines achieved



As reported, the first produced pump has been successfully installed in a steam turbine of Shahid Salimi (Neka) Power Plant in northern Mazandaran Province.To get more news about Screw Pump, you can visit hw-screwpump.com official website.

According to Hossein-Ali Taziki, who is a deputy manager at the mentioned power plant, before Iran, only a few developed countries like Sweden, the U.S., Germany, and the UK had access to the knowledge for manufacturing such pumps.

A screw pump is an axial-flow gear pump, similar in operation to a rotary screw compressor. Three types of screw pumps include the single-screw, two-screw, and three-screw.

In the single-screw pump, a spiraled rotor rotates eccentrically in an internal stator. The two-screw pump consists of two parallel intermeshing rotors rotating in a housing machined to close tolerances. The three-screw pump consists of a central-drive rotor with two meshing idler rotors; the rotors turn inside of a housing machined to close tolerances.
The Benefits Of Screw Pumps
Fluid flow processes are one of the five main classes of unit operations in chemical processing. Fluid flow processing, as you know, includes the transfer, filtration, solids fluidization and transportation activities. Centrifugal pumps have been the preferred industry standard to manage fluid flow processing, but in some cases these pumps can be inefficient and costly.

Positive Displacement (PD) screw pumps can be a viable alternative to centrifugal pumps, when such inefficiency is found. The PD screw pumps are designed to handle a wide variety of liquids, including those with higher viscosities. Benefits of screw pump technology in chemical fluid processing include the ability to handle a wide range of flows, pressures, liquid types and viscosities, offering a constant flow despite backpressures, and many more.
