[0090] On-site Spraying of Anti-Erosion and Abrasion Coating on Water Cooling Wall of Power Plant Boiler

[0091] 1. Conditions of use: The surface of the water cooling wall has been damaged after long-term use and needs to be repaired. The temperature of the water-cooled wall is about 300°C. During use, it is subjected to the erosion and wear of coal powder, the corrosion of coal smoke and high-temperature heat radiation. In the process, there will be no defects such as layer drop and block that affect performance.

[0092] 2. Coating design: According to the conditions of use and the requirements for coating quality, select NiCr / CrC spraying core wire, the specification and size of the spraying wire are all Φ2mm, and the coating thickness after spraying should be > 0.18mm.

[0093] 3. Spraying process: use the spraying equipment of the present invention, adopt manual operation spraying operation mode.

[0100] Field Construction Spraying of Anticorrosion Coating on Gas Pipeline Surface

[0101]1. Current status of use: In the laying of gas pipelines in small and medium-sized cities along the coast, many pipelines are exposed to the humid atmosphere, and some pipelines are elevated in the air. After several years of use, the galvanized layer or paint protective layer on the surface appears. Exfoliation corrosion phenomenon. If the paint is repainted, the service life is relatively short. If the new pipeline is replaced, the gas must be stopped, and the construction period is long, which affects people's normal life, and the cost is also high. The method of spraying can solve these problems, but it is very inconvenient to work in the field and in the air. The spraying equipment of the present invention can realize the construction of the project conveniently due to its small size, light weight, few external cables, and flexible operation.

Abstract

The invention relates to an integral push-wire-type electric arc spraying equipment used for thermal spraying, which can be seen in an attached figure of the abstract. The equipment adopt an inverter-type spraying power supply, has the technical scheme of combining and closing the spraying power supply, a wire feed device and a wire reel bracket (including a wire reel) into a whole body, and is matched with a home-made electric arc spray gun. The integral push-wire-type electric arc spraying equipment solve the problems of heavy weight, large volume, dispersed devices, more externally connected cables and the like of the push-wire-type electric arc spraying equipment. The equipment have the function of stepless regulation for output voltage within the range of 10-50V, and can freely adjust the parameters without stopping a machine in the spraying process; the equipment is provided with a manual / automatic spraying and wire detection / spraying switch, thus being convenient for the selection of operation way and preventing electric arc from hurting people and damaging equipment when in the process of installing, adjusting and checking spraying wires; and due to the full-closed structure, the blockage phenomenon of a wire guide pipe is avoided. The equipment has the characteristics of small volume, light weight, convenient carrying, safe and reliable equipment performance, convenient use, simple operation, stable spraying quality and the like.

Description

Technical field: [0001] The invention belongs to the technical field of surface engineering subject spraying, and is a novel combined structure arc spraying equipment in the arc spraying technology. Background technique: [0002] Surface engineering is a comprehensive new subject. Spraying technology is a very important surface modification technology in the subject of surface engineering. Due to its strong application value and significant economic and social benefits, it also saves energy and The superiority reflected in resources, maintenance and remanufacturing, environmental protection and pollution, etc., has effectively promoted the rapid development of this technology. In recent years, many new achievements have been made in spraying methods, equipment, processes, materials, etc. The present invention is a new type of arc spraying equipment, which is used for the preparation of coatings in the field of thermal spraying. [0003] The principle of arc spraying is diff...
