Taking the titanium alloy centrifugal pump technology as an example, in order to realize the lightweight, seawater corrosion resistance and service life of the pump equipment, Replace the original copper alloy with titanium alloy with better corrosion resistance, mass density, material strength, which mainly replace the materials of flow passage parts such as pump body, impeller, and pump shaft, so as to realize the use in seawater environment.
The main technical indexes are flow 20 ~ 150 m3 / h, lift 30 ~ 90 m, suction height 3.5 m, cavitation allowance 4 m, etc; The main technical difficulties are the casting process of main parts (pump body, impeller, guide vane) and other castings, and the research on the corrosion resistance of the whole material of the pump set in different sea areas.
Importance analysis: the titanium alloy centrifugal pump has a direct impact on the flow, head, and cavitation allowance of the seawater pipeline system, it then directly affects the service life of the pipeline and the whole system.
Novelty analysis: titanium centrifugal pump adopts new materials, which have been used on civilian ships before, while it has not been used in a seawater environment. This paper requires that corrosion, antifouling, and other factors should be considered when used in a seawater environment. The service environment has changed greatly and there are technical risks.
