Water seepage in explosion-proof control cabinets is mostly caused by heavy rain washing. In humid environments, household appliance pipes may experience condensation due to thermal expansion and contraction. By comparing the main causes of water seepage in explosion-proof control cabinets, measures to avoid seepage can be found.

Some explosion-proof control cabinets do not have sealing rings and are very prone to water ingress.。The failure of raised faces, fastening screws, and sealing gaskets is also an important cause of water ingress.。

1. For horizontal assembly of explosion-proof control cabinets, the raised faces should not use recessed screw holes.。The screw holes must be sealed with grease or other materials.。avoidanceLevelPermeatePermeableAchieveScrewHole。

2. Applying phosphating paste or anti-rust agent on the flameproof surfaces can reduce the adverse effects of rust on the flameproof surfaces and enhance the waterproofing function of the ground.。

3. Maintenance of explosion-proof control cabinets is relatively strict. To avoid maintenance difficulties caused by bolt breakage in the enclosure, the enclosure of explosion-proof control cabinets should use blind holes as much as possible, reducing threaded holes to facilitate the removal of dirt and debris.。

4. Sealing gaskets should be intact and elastic, and should be properly positioned during assembly. The use of sealing rings with joints is not recommended.。

5. The tightening of enclosure bolts should be uniform and consistent. Customers should strictly implement this during installation, especially when using stainless steel screws.。Stainless steel screws are aesthetically pleasing and not prone to rust, but they have low strength and are easily damaged, failing to achieve the corresponding torque, resulting in excessive gaps on the flameproof surfaces and failure to meet explosion-proof performance requirements.。
