AI Technical Summary
The front and rear casings of explosion-proof centrifugal blowers are prone to rust in high humidity or damp environments, which reduces their fixing strength and affects the stability and safety of the equipment.
The system employs hexagonal bolts and a sealing mechanism. By continuously screwing the nut into the hexagonal bolts, the sealing mechanism seals the hexagonal holes. The sealing component also seals the internal thread groove, preventing external humid air from contacting the bolts and nuts and thus preventing corrosion.
It effectively prevents hexagonal bolts and nuts from rusting due to contact with moisture, improves fixing strength, enhances equipment stability and safety, and reduces the risk of equipment damage.
