Ubufakazi bokuqhuma kwe-Shenhai
1. Explosion-Proof Markings
Explosion-proof designations, njenge “Exd II CT6,” kufanele imakwe ngokucacile noma iphonswe ebhokisini elingaphandle lempahla.
2. Product Nameplate
• Explosion-proof markings;
• Inombolo yesitifiketi engaqhumi;
• Uphawu lwelayisensi yokukhiqiza;
• Izidingo ezithile;
• Usuku lokukhiqiza/inombolo ye-serial.
3. Overall Appearance
• Explosion-proof metal enclosures: Ensure wall thickness and surface finish (casting and argon welding) are smooth and free from irregularities to meet explosion strength standards and porosity requirements.
• Larger products should maintain effective heat dissipation and meet temperature classification needs to extend service life.
• Equipment should feature both internal and external grounding with clear grounding indications.
• Check the configuration of electrical entry devices to support necessary construction wiring.
4. Structural Rationality
Components such as decoder boxes and power supply units should accommodate a specific number of circuits and the maximum allowable current and power.
