Shenhai Explosion-Proof
I roto i te tupuraa o te mau matini uira i faahepohia, Ua riro te hi'opo'a-maite-raa i te faanahoraa paruru o te manureva ei taahiraa faufaa roa no te tape'a i te mau rave'a paruru o te mau matini. Ua riro teie tuhaa ei tapao faufaa roa o te mau matini uira i faaohipahia.
Te ravea parururaa ohie i roto i te faanahoraa parururaa, tasked with monitoring and managing the system’s operational status, must not become an ignition source for combustible gases. It should either meet specific explosion-proof standards or be located in areas free from Te mau mana'o tauturu no te Te mau nota. Designers must prioritize this factor in their planning.
When integrating explosion-proof automatic safety devices, designers should follow these guidelines:
1. No te mea “Pb” class pressurized electrical equipment, the automatic safety device’s explosion-proof classification can utilize various types conforming to Ga “Ma” or Gb “Ma” protection levels.
2. No te mea “Te mau mana'o tauturu no te” class pressurized electrical equipment, different explosion-proof classifications can be used for automatic safety devices, each corresponding to varying levels of explosion-proof protection.
Hau atu â, it’s crucial to recognize that various automatic safety devices are indispensable components of the pressurization protection system. They must consistently provide reliable
“service” before, during, and after the system operates. No reira, the power source for these safety devices should not coincide with the main circuit. Te mea maitai roa a'e, it should be placed before the main circuit’s Te mau mana'o tauturu no te haapiiraa or power switch to ensure uninterrupted service, even in the event of a main circuit power outage.
