Daily Protection and Inspection of Spiral Air Duct Machine

The spiral duct machine is a machine for producing spiral ducts. Spiral ducts, also known as spiral seam thin-walled ducts, were first used in the military industry of Western countries, such as warships, ship platoon (sending) air systems, and later in civilian facilities such as trains, subways, and mines.

1. Daily protection of spiral duct machine

Because metals are prone to chemical reactions in the environment, they can cause corrosion and rust. There is almost no change in zinc in dry air. In argon, dense alkaline zinc carbonate film spirals are formed on the zinc surface. Coat a layer of zinc on the pipe for protection. Zinc coating can significantly improve its protective and decorative properties through passivation treatment, dyeing or coating protective agent.

Spiral duct machine is the equipment to produce spiral duct, so the equipment's technological process planning and general protection, general quality inspection, etc. have a great relationship. Doing a good job in the maintenance of the spiral duct machine can prolong the service life of the spiral duct machine and avoid certain damages and mechanical failures.

2. Detailed steps of quality inspection of spiral duct machine

Incoming inspection, also known as in-factory inspection: This is the inspection of incoming materials, such as raw materials and purchased parts, by the inspection department before entering the warehouse. The purpose of this is to understand whether the quality of the raw materials provided by the supplier can meet the production quality requirements, and to formulate relevant acceptance standards for subsequent batch acceptance.

Process inspection inspects the quality of the spiral duct machine or its parts and the quality-related elements in the production process. The purpose of the process inspection is to prevent the unqualified spiral duct machine from entering the next process and avoid batches of unqualified products. Once the inspection is unqualified, the cause should be quickly identified, corrective or improvement measures should be taken in time, and the non-conforming products should not be transferred to the next process. If a large number of non-conforming products are found, the processing should be stopped in time and reported to the relevant department. Processing can only be continued after measures have been taken to re-inspect and pass the inspection.
