Embodiment 1

[0024] A seawater pump comprises a pump barrel, an outlet elbow, an impeller, a bell mouth and an impeller chamber, and the pump barrel, the outlet elbow and the bell mouth are made of graphene fiber / carbon fiber composite fiber material.

[0025] It adopts an electric heating mandrel, and after the graphene / carbon composite fiber is bundled and dipped, it is directly wound on the electric heating mandrel under tension control; at the initial stage of winding, the mandrel is heated at a constant temperature of 100°C until the wound graphene / The thickness of the carbon composite fiber layer reaches 1 / 4 of the preset winding thickness; then, the mandrel is heated up gradually at a heating rate of 5°C / 0.1mm winding thickness until the preset winding thickness is reached, and the winding stops; then the mandrel is in Carry out constant temperature heating at 140°C until the curing and molding of the graphene / carbon composite fiber pump barrel, outlet elbow and bell mouth are compl...

Abstract

The invention discloses a sea water pump. The pump comprises a pump cylinder, an outlet bend, an impeller, a horn mouth and an impeller chamber; the pump cylinder, the outlet bend and the horn mouth are made of graphene fiber / carbon fiber composite fiber materials; a sea water pump component is prepared through the fiber winding technology, metal of the pump component is replaced with the composite fiber material, the strength superior to that of the metal component can be provided, meanwhile, corrosion resistance is better than that of the metal component, and therefore the pump can be perfectly used for the seabed.

Description

Technical field [0001] The present invention relates to the field of pumping technology, and in particular to a seawater pump. Background technique [0002] Seawater pumps are suitable for fire protection on offshore platforms, equipment heat dissipation, seawater desalination, and can also be used for ground source heat pump air conditioning heating in coastal areas, all seawater lifting, coastal square fountain landscapes, seawater aquaculture, etc. [0003] As a key equipment for transporting seawater, seawater pumps are widely used in offshore platforms, land terminals and other occasions. Seawater pumps are immersed in seawater for a long time, and the materials of the seawater pump are required to have strong anti-corrosion capabilities. The material selection and manufacturing process of seawater pumps are crucial. [0004] Seawater corrosion mainly occurs in three aspects: first, the natural oxidation corrosion of materials in seawater; second, corrosion caused by ...
