Inspection and Protection of Spiral Duct Machine

1. Detailed Steps of Quality Inspection of Spiral Duct Machine

Incoming inspection, also known as in-factory inspection is the inspection conducted by the inspection department on incoming materials, such as raw materials, purchased parts, etc., before entering the warehouse. The purpose of the inspection is to understand whether the quality of the raw materials provided by the supplier can meet production quality requirements or not, and formulate relevant acceptance standards for subsequent batch acceptance.

It is to inspect 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 unqualified 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 passing the reinspection.

2. The Protection of the Spiral Duct Machine

Metals are prone to chemical reactions in the environment, leading to corrosion and rust. But there is almost no change in zinc in dry air. In argon, dense alkaline zinc carbonate film spirals are formed on the zinc surface. A layer of zinc on the pipe can protect the pipe. Zinc coating can significantly improve its protective and decorative properties through passivation treatment, dyeing or coating protective agent. Spiral duct machine is the equipment for producing spiral duct, so the process planning of the equipment has a great relationship with general protection and general quality inspection. A good job in the maintenance of the screw pipe machine can prolong the service life of the screw pipe machine and avoid damage and mechanical failure.
