Paint spraying technique of plate radiator for transformer

Abstract

The invention discloses a paint spraying technique of a plate radiator for a transformer. The paint spraying technique is implemented in paint spraying pools; the paint spraying pools consist of a priming paint spraying pool, an intermediate paint spraying pool and a finishing paint spraying pool; two support frames are arranged at the bottom of each paint spraying pool; the radiator is arranged on two support frames; inverted conical sinks are arranged at the bottoms of the paint spraying pools; paint spraying pumps are arranged on the lower parts of the inverted conical sinks, and are connected with paint spraying guns by hoses; and operators implement the paint spraying for the radiator through the paint spraying guns. The paint spraying technique comprises the following steps: a. inspecting the radiator; b. preparing the paint spraying pools; c. preparing paint; d. spraying priming paint; e. spraying intermediate paint; f. spraying finishing paint; and g. processing the surface. According to the paint spraying technique of the plate radiator for the transformer, disclosed by the invention, the thicknesses of paint films are uniform, so that the heat dissipation of the radiator is evener; the surface of the radiator is difficultly oxidized, so that the service life of the radiator is prolonged; and the productivity is high, so that the invalid working hours are shortened.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a varnishing process for chip radiators used in transformers. Background technique [0002] With the rapid development of social economy, my country's power industry is also growing. Transformers are essential power equipment in the power industry. Oil-immersed transformers are the most widely used transformers in various transformers. Existing oil-immersed transformers are equipped with chip radiators to ensure the normal operation of the transformer. [0003] After the radiator is assembled and welded, the surface should be painted. At present, artificial painting or spray painting is used, which has the following disadvantages: 1. The thickness of the paint film is not uniform, resulting in uneven heat dissipation of the radiator; 2. Some parts The paint film is thin and even cannot be sprayed, which will cause these parts to be easily oxidized and shorten the service lif...

Problems solved by technology

[0003] After the radiator is assembled and welded, the surface should be painted. At present, manual painting or spray painting is used, which has the following disadvantages: 1. The thickness of the paint film is uneven, resulting in uneven heat dissipation of the radiator; 2. Some parts The paint film is thin, even if it cannot be sprayed, it will cause these parts to be easily oxidized and shorten the service life of the radiator; 3. Low production efficiency
