Inner container coating used for lightweight submersible pump, and preparation method thereof

Abstract

The invention discloses to an inner container coating for a lightweight submersible pump, and relates to the technical field of production and processing of pumps. The coating comprises acrylic resin, isocyanate, lithopone, polyamide, aluminum nitrate, magnesium chloride, carbon fiber powder, triethanolamine, rosin, cyclohexanol, polyethylene wax, toluene, EVA resin, calcium bentonite, silica powder, calamine powder, wood glue powder, deionized water, an antirust agent, a composite reinforcing agent, an antifoaming agent and a thickener. The antirust agent and the composite reinforcing agent are used to modify a coating in order to increase the antirust property and the hardness of the coating, and antirust powder-containing components in the antirust agent added to the coating can help the coating to form a film on an inner container in order to improve the antirust ability of the inner container, so the pump body of the water pump is protected, the resistance of the submersible pump to low-oxygen humid environment is effectively improved, and the service life of the submersible pump is prolonged.

Description

Technical field: [0001] The invention relates to the technical field of water pump production and processing, in particular to a liner coating for a lightweight submersible pump and a preparation method thereof. Background technique: [0002] A water pump is a machine used to increase the pressure of a liquid to make it flow. It is a device used to move a liquid or a special fluid medium, that is, a machine that does work on the fluid. Water pumps have different purposes, different conveying liquid media, different flow rates and head ranges. Therefore, of course, their structural forms are also different, and their materials are also different. However, there is an essential part in all water pumps - the vane wheel. The vane wheel provides flow force for the liquid by rotating, so as to realize the delivery of the liquid. However, due to the different environments and purposes of the pump, the fluid delivered by the pump Not the same as liquids, there are many liquids and ...

However, there is an essential part in all water pumps - the vane wheel. The vane wheel provides flow force for the liquid by rotating, so as to realize the delivery of the liquid. However, due to the different environments and purposes of the pump, the fluid delivered by the pump Not the same as liquids, there are many liquids and fluids that can cause damage to the pump;

[0003] Submersible water pumps have a wide range of applications. Due to the different requirements for using submersible pumps in different installation environments, the quality of submersible pumps will also vary. In many cases, submersible pumps with lighter weight are required to work and use. Therefore Many light-weight materials are used for the processing and production of submersible pumps. However, the lightweight submersible pumps currently on the market have not undergone special treatment in terms of corrosion resistance and oxidation, and the use of them consumes a lot.
