A kind of preparation method of composite plating solution for floating aerator bearing inner bushing

Abstract

The invention relates to a composite coating solution for a bearing inner shaft sleeve of a floating aerator. The composite coating solution for the bearing inner shaft sleeve of the floating aerator relates to the technical field of chemical coating preparation, and is prepared from the following raw materials: 600 to 700 parts of boron carbide, 120 to 130 parts of nickel sulfate, 150 to 250 parts of boracic acid, 6 to 8 parts of cobaltous sulfate, 25 to 35 parts of coumarin, 35 to 45 parts of wetting agent, 5 to 7 parts of dipentaerythritol, 80 to 90 parts of gelatin, 60 to 80 parts of sodium nitrate, 10 to 20 parts of sulfamic acid, 15 to 25 parts of lactic acid, 6 to 8 parts of saccharin, and 2,200 to 2,300 parts of deionized water. The composite coating solution for the bearing inner shaft sleeve of the floating aerator provided by the invention has the beneficial effects that the technological process is concise, the raw material ratio is reasonable, the problem that a metal material under a special environment cannot meet the physical and chemical requirements is solved, the using effect is obvious, the composite coating solution is high-temperature-resistant and wear-resistant, and the safety performance of the bearing inner sleeve of the aerator is ensured.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment processing, in particular to a method for preparing a composite plating solution for inner shaft sleeves of floating aerator bearings. Background technique [0002] The floating aerator injects "micro-bubbles" directly into untreated sewage. Under the joint action of coagulant and flocculant, the suspended solids undergo physical and chemical flocculation, thereby forming large suspended solids flocs. Under the action of the buoyancy of the bubble group, the "flocculation" floats to the liquid surface to form scum, which is separated from the water by a slag scraper, without cleaning the nozzle, and will not cause clogging. For a long time, floating aerators in the same industry have been working in sewage , the airflow pressure of the air pump makes the bearing on the shaft support point of the floating aerator not fully lubricated, and the heating and expansion will damage the ...

[0002] The floating aerator injects "micro-bubbles" directly into the untreated sewage. Under the joint action of coagulant and flocculant, the suspended solids undergo physical and chemical flocculation, thereby forming large suspended solids flocs. Under the action of the buoyancy of the bubble group, the "flocculation" floats to the liquid surface to form scum, which is separated from the water by a slag scraper, without cleaning the nozzle, and will not cause clogging. For a long time, floating aerators in the same industry have been working in sewage , the airflow pressure of the air pump makes the bearing on the shaft support point of the floating aerator not fully lubricated, and the heat and expansion will damage the motor and cause the main engine to fail to work. Therefore, most of them use rubber bearings instead, but they are also not lubricated during use, and The rubber expands when heated, which will lock the journal, damage the motor, and cause the main engine to fail to work. Therefore, processing high temperature resistant and bearing inner shaft sleeves is the main subject of current technical research.
