Abstract
The invention discloses an alloy pump for conveying chlorine-containing mixed acid liquid. The key points of the alloy pump are that an overflow part and a pump shell of the alloy pump comprise the following components in percentage by weight: 0.05 to 0.12 percent of carbon (C), 1.0 to 3.0 percent of manganese (Mn), 0.20 to 1.2 percent of aluminium (Al), 8.0 to 18.0 percent of molybdenum (Mo), 8.0 to 12.0 percent of nickel (Ni), 12 to 20 percent of chromium (Cr), 0.5 to 1.2 percent of copper (Cu), 0.2 to 2.5 percent of silicon, 0.05 to 0.3 percent of nitrogen and the balance of ferrum (Fe); and the components are mixed uniformly and melted to perform cast moulding. In the overflow part and the pump shell of the alloy pump, the corrosion-resistant components of C, Mn, Al, Mo, Ni, Cr, Cu, Si and N are added into the Fe component, so that the chloride ion corrosion resistance of the overflow part of the alloy pump is improved, the service life of the alloy pump is longer than that of other stainless steel or alloy pumps, and the alloy pump is particularly suitable for conveying the high-temperature chloride ion-containing mixed acid liquid. The alloy pump solves the technical problem of easy corrosion in the prior art.
Description
Technical field
The invention belongs to triethyl orthoformate and produce the liquid delivery pump technical field, relate to the alloy pump that a kind of nitration mixture liquid that is used for chloride is carried.
Background technology
In chemical enterprise, being used for the pump that delivery temperature is higher than 90 ℃ the nitration mixture liquid that contains chlorine root etc. can break down because of corrosion, and therefore causes frequent parking, changes pump, needs the configuration stand-by pump and has increased investment.
Summary of the invention
The objective of the invention is to solve prior art and have corrosion-prone technical problem, the alloy pump that provides a kind of nitration mixture liquid that is used for chloride to carry is to overcome the deficiency of prior art.
To achieve these goals; The present invention is used for the alloy pump of chloride nitration mixture liquid conveying; Its main points are that the flow passage components and the pump case of alloy pump is made up of following compositions in weight percentage: C 0.05-0.12%, Mn1.0-3.0%, Al 0.20-1.2%, Mo 8.0-18.0%, Ni 8.0-12.0%, Cr 12-20%, Cu0.5-1.2%, Si 0.2-2.5%, N 0.05-0.3%, surplus are Fe, with said components mixing fusing cast molding.
The overcurrent position and the pump case of alloy pump of the present invention; Be in the Fe component, to add corrosion-resistant component C, Mn, Al, Mo, Ni, Cr, Cu, Si and N; Thereby strengthened the corrodibility of the overcurrent position anti-chlorine ion of pump; Than other stainless steels or alloy pump there is longer work-ing life, is specially adapted to the conveying of the nitration mixture liquid of temperature height, chloride ion-containing.Solved the corrosion-prone technical problem of prior art.
Embodiment
The flow passage components of alloy pump of the present invention and pump case are made up of following compositions in weight percentage: C 0.8%, Mn 2.0%, Al 0.7%, Mo 13.0%, Ni 10.0%, Cr 16%, Cu 0.8%, Si1.0%, N 0.1%, surplus are Fe, with said components mixing fusing cast molding.
