Shenhai Explosionssäker
1. Säkerställ att explosionssäker elektrisk utrustning och dess närhet är ren, fritt från något obstruktivt skräp.
2. Confirm the sturdy fixation of explosionssäker elektrisk utrustning, kontrollera om det är intakt hölje, täta skruvar, och frånvaro av korrosion.
3. Verifiera stabiliteten hos de elektriska inmatningsenheterna, intakta sälar (including multiple wiring entries), and secure connections.
4. Inspect the integrity of the grundstötning wire for the explosion-proof equipment, checking for corrosion, detachment, and undamaged steel wire on armored cables.
5. Assess the reliability of interlocking mechanisms on the explosion-proof electrical equipment.
6. Ensure temporary lines and devices at the site adhere to explosion-proof standards.
7. Validate the normal functioning of explosion-proof electrical equipment, with operational parameters like current, voltage, tryck, och temperatur within permissible ranges.
8. Check that junction boxes, input devices, isolation seal boxes, and flexible conduits meet explosion-proof standards.
9. Inspect for significant corrosion on the casing of motors, electrical components, instrument, and equipment bodies, ensuring the soundness of anti-loosening and screw-lock interlocking devices.
10. For oil-filled explosion-proof devices, ensure oil levels are above the indicator line, check for clear oil indicators, discharge facilities, and no leakage or seepage.
11. Confirm that the air source and pressure for pressurized explosion-proof devices comply with requirements, and the pressure alarm system is functional.
12. Examine cables or steel conduits for any looseness, detachment, damage, eller korrosion. Ensure reliable grounding connections, rust-free grounding devices, and acceptable grounding resistance.
