Description

technical field [0001] The invention relates to the field of chemical pump casing manufacturing, in particular to a corrosion-resistant chemical pump casing. Background technique [0002] Chemical pumps are mainly used to transport chemical materials, and most chemical pumps are used in harsh environments. During the process, they will be exposed to corrosive substances such as strong acids and alkalis. When chemical pumps are placed in the open environment, they will be exposed to ultraviolet rays, rain and snow and Corrosion, therefore, the casing of the chemical pump needs to have greater strength and corrosion resistance. Existing chemical pump casings are usually made of aluminum alloy die-casting or cast iron pump casings, which are heavy in weight, high in production cost, and have low corrosion resistance. Contents of the invention [0003] The present invention is realized through the following technical solutions: [0004] A corrosion-resistant chemical pump ca...
