Abstract
The invention discloses the impeller of Pendular ring type chlorine gas pump, the impeller is by following composition mass percentage composition: C 3.2-3.8, Si 2.1-2.6, Mn 0.3-0.5, P < 0.1, S < 0.03, Mg 0.03-0.05, RE 0.02-0.04, Cr 0.2-0.6, Cu 1.8-2.0, Al 0.6-1.1, Mo 1.0-1.25, Fe 87.93-90.75.Impeller of the invention is manufactured by above-mentioned heat-proof nodular cast iron, is enhanced the wearability and corrosion resistance of impeller, is extended service life, reduce maintenance cost, improve production efficiency.
Description
Technical field
The present invention relates to Pendular ring type chlorine gas pumps, and in particular to the impeller of Pendular ring type chlorine gas pump.
Background technique
Currently, the impeller of Pendular ring type chlorine gas pump mainly uses HT200 or HT250 to cast, building ring of the impeller in chlorine gas pump
It is contacted in border with acid, through acid attack rear surface is uneven or even blade crushes, high-temperature heating expansion causes pump to be killed, to making
Ground out of order disastershutdown is caused with producer, influences production efficiency.
Summary of the invention
It is an object of the invention to: a kind of impeller of Pendular ring type chlorine gas pump is provided, the impeller corrosion resistance and wearability are preferable,
Prolong the service life, reduce maintenance cost, improves production efficiency.
The technical solution of the invention is as follows: the impeller is by following composition mass percentage composition: C3.2-3.8, Si2.1-
2.6, Mn0.3-0.5, P < 0.1, S < 0.03, Mg0.03-0.05, RE0.02-0.04, Cr0.2-0.6, Cu1.8-2.0,
A10.6-1.1、Mo1.0-1.25、Fe87.93-90.75。
Impeller of the invention is made by above-mentioned heat-proof nodular cast iron, enhances the wearability and corrosion resistance of impeller, extends
Service life reduces maintenance cost, improves production efficiency.
