Requirements for Intermediate Support Packing Devices
The construction of a packing device is an important step in industrial production. Middle support packing devices are often used in many cases, such as chemical, petroleum, and electric power engineering. The relevant requirements for middle support packing devices are as follows:
1. Structure Requirements
The middle support packing device should have a reliable structure, precise size and precise appearance. The packing device can be disassembled, assembled, inspected and maintained conveniently. The surface of all parts of the packing device should be smooth, defect-free, not corroded, and the surface treatment is preferably galvanized.
2. Material Requirements
In principle, the material of the packing device should use the national standard. Its weldability, machinability and plasticity should be good. Materials used for the plane and standard parts of the packing device should generally use iron or iron-based materials, and their properties should meet the requirements of the corresponding standards.
3. Technical Requirements
The plane tolerance and cylindricity tolerance of key components of the packing device should generally be within the range of IT7-IT8. The roughness of the inner and outer surfaces of the middle support packing device should be Ra<1.6. The surface of the plane and cylindrical parts should be treated by sandblasting or other similar processes. All parts of the packing device should be smooth without micro burrs and without welding flash, slag, and slag inclusion. The packing device must be under static and dynamic balance before leaving the factory.
4. Quality Requirements
The hardware, such as nuts and screws, of the packing device must be made of fine material, and the quality of the assembling parts should be checked one by one. All non-standard parts and other components of the packing device should have complete drawings sealed by the designer, and all operational processes must be done in strict compliance with the drawings. The tolerance in the drawings should meet the corresponding requirements.
5.Packing Requirements
The middle support packing device should be firmly packed before leaving the factory. Rainproof sheets and plastic film should be used around the packing device to ensure that the product is in good condition during transportation and storage.
In summary, the related requirements of middle support packing device should be taken seriously in industrial production. Enterprises should strict inspect the raw material, strictly operate according to the technical process, and carefully check the product appearance and parts performance under careful operation, also should frequently maintain and check the middle support packing device components. Those efforts would greatly guarantee the production safety and product quality.
