Problems solved by technology

[0006] The present invention can solve the problem that in the existing coating process, since the blade part in the steam turbine is a twisted structure, the commonly used coating nozzles are mostly fixedly connected so that the commonly used coating nozzles cannot perform targeted spraying according to the shape of the blades. After spraying by the coating nozzle, the thickness of the sprayed coating on the upper half of the blade is often greater than that on the lower half, resulting in uneven coating. Commonly used coating nozzles still have residual coating liquid dripping after spraying. And long-term contact with air is easy to make the residual coating liquid solidify and block the coating nozzle

Abstract

The invention relates to a steamer coating production line of a steam turbine and a coating method thereof. An electric rotary disc, an inner diameter clamp, an electric lifting rod, a connecting frame, two angle adjusting frames, first nozzles and second nozzles are included; the inner diameter clamp is installed at the upper end of the electric rotary disc, the right end of the electric rotary disc is equipped with the electric lifting rod, the upper end of the electric lifting rod is provided with the connecting frame, the lower end of the connecting frame is provided with the two angle adjusting frames, the outer side of the lower end of each angle adjusting frame is provided with the corresponding first nozzle, and the inner side of the lower end of each angle adjusting frame is provided with the corresponding second nozzle. The steamer coating production line can solve the problems that in the conventional coating process, most common coating nozzles adopt a fixed connecting manner so that the common coating nozzles cannot conduct spraying according to blade shapes, the thickness of a spraying layer on the upper half part of a blade is often larger than the thickness of a spraying layer on the lower half part after spraying with the common coating nozzles, and vestigital coating liquid still drips after spraying with the common coating nozzles is completed.

Description

technical field [0001] The invention relates to the field of steam turbine coating, in particular to a steam turbine coating production line for steam turbines and a coating method thereof. Background technique [0002] The steam turbine, also called the steam turbine engine, is a rotary steam power device. The high-temperature and high-pressure steam passes through the fixed nozzle and becomes an accelerated air flow, and then sprays onto the blades, so that the rotor equipped with blade rows rotates and works externally. The steam turbine is a modern The main equipment of the thermal power plant is also used in the metallurgical industry, chemical industry, and ship power plant. Among them, the steam turbine is an important component part of the steam turbine, and the steam turbine needs to be painted during the steam turbine processing process. However, The following problems are often encountered in the existing painting process: [0003] 1. Due to the twisted structure...
