Embodiment Construction

[0010] The following describes the preferred embodiments of the present invention. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0011] A method for preparing a fire pump guide vane with a coating, comprising the following steps: pretreatment, after removing oil stains, iron and scale impurities on the surface of the guide vane; in the first step, the pretreatment is organic solvent, alkaline Cleaning agent degreasing, shot blasting, shot blasting or sandblasting. The coating is to spray or impregnate the guide vanes of the fire pump with Dacromet solution, and then use centrifugal drying, natural vertical flow, and brush to remove excess treatment liquid; among them, Dacromet treatment liquid is composed of aluminum particles, chromic anhydride and resin Composition, solidified into a three-dimensional film layer network structure. Bak...

Abstract

The invention discloses a preparation method for a fire pump guide vane with a coating. The preparation method comprises the following steps of preprocessing to remove oil stain, iron and scale impurities on the surface of the guide vane; spraying the fire pump guide vane with a dyclonine solution or dipping the fire pump guide vane in the dyclonine solution, then removing the redundant treating solution through centrifuge dripping, natural vertical flowing and brushing; and baking in a circulating hot air baking oven during the process of converting the dyclonine treating solution on a guide vane matrix into a film, then cleaning and polishing the guide vane.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting machinery, in particular to a method for preparing a fire-fighting pump guide vane with a coating. Background technique [0002] The fire pump is a special pump installed on ships, fixed fire extinguishing systems or other fire fighting facilities, and used to transport liquid fire extinguishing agents such as water or foam solution. Due to the complex structure of fire pumps and easy wear and tear, professional and technical personnel are required to improve fire pump components to meet the needs of life. Contents of the invention [0003] The invention aims to overcome the defects of the prior art, and provides a method for preparing a coated fire pump guide vane, which has the characteristics of good rust resistance and stable quality. [0004] In order to solve the above technical problems, the present invention provides the following technical solutions: [0005] A method for prepar...
