Annunciator coating repairing technique

Abstract

The invention discloses an annunciator coating repairing technique. By the adoption of the annunciator coating repairing technique, an insulating coating with the cracks exceeding the standard or a chipping coating of an annunciator can be repaired, so that the use function of the coating is recovered. The annunciator coating repairing technique comprises the specific steps that firstly, coating residues on the annunciator are removed; secondly, lubricating oil in a shell is removed; thirdly, the annunciator is protected; fourthly, gluing is conducted; and fifthly, finishing and inspection are conducted. The repairing method has been used for repairing test samples and taken part in a test run examination of a factory; after the test run, it is shown through appearance inspection that the coating is free of cracks and chipping faults, the performance of the coating is qualified, the state of the coating is good, and the use requirement of an engine can be met; by the adoption of the repairing method, the cost can be greatly reduced for the factory; the repairing method can also be popularized to be used for repairing other engines; machine parts rotates at a constant speed, and formation of the coating can be effectively guaranteed before solidification. A fixing rod on a clamp is designed to be of a multi-section type, so that repairing of multiple accessories can be achieved at a time, and the production efficiency is multiplied.

Description

Technical field: [0001] The invention relates to the technical field of coating repair of electrical accessories, in particular to a process method for coating repair of annunciators. Background technique: [0002] During the engine repair process, when an electrical accessory was inspected, it was found that the insulating coating often had cracks exceeding the standard or the coating fell off, resulting in the electrical accessory not being able to work normally. In order to ensure the assembly needs of the engine, only new spare parts can be purchased, which costs a lot of money and cannot ensure the engine repair cycle. Therefore, it is urgent to repair the insulating coating on the faulty parts to meet the repair requirements of the engine. Invention content: [0003] The purpose of the present invention is to provide a process method for repairing the coating of an annunciator, which can repair the coating of an annunciator whose insulating coating cracks exceed the...
