Three types of connections~Why can the third type prevent static electricity?~ ?
Thread Content
As shown in the figure: This is the shape of the feed liquid inlet mentioned in the HG/T3983 standard. For the third type, why can it prevent static electricity? If the material of this tank (or reactor) is metal, that makes sense~ This is a standard for winding large-scale fiberglass-reinforced plastic components on-site; but how can it be understood as providing static electricity protection when the material is non-metallic? I asked my colleagues and some of them said ； Prevent friction with air during feeding when the material level is low? So when it’s in contact with the wall, won’t the material rub against the non-metallic inner wall? I hope the expert can help me resolve my doubts~ Thank you~
Reducing the agitation and friction of materials means reducing the generation of static electricity; it’s not about conductivity
The medium flows downward along the wall of the vessel, reducing the likelihood of static electricity being generated due to impacts.
Flowing down the wall reduces stirring, impact, and backmixing.
Reduce flow rate to decrease static electricity generation? ? ?
Coasting flow to reduce impact and static electricity
