Tsanangudzo yeMetal Materials for Explosion-Proof Electrical Equipment

Chinhu chakakosha chekufunga nezvezvinhu zvesimbi mumidziyo yemagetsi-inoputika isimba ravo rekubatidza zvinoputika gasi-mhepo musanganiswa kuburikidza nemagetsi.. Tsvagiridzo yakaratidza kuti kuumbwa kwesimbi idzi kunoita basa rakakura mukupisa kwadzo. Kudzivirira kuitika kwe mechanical spark ignition mumasimbi esimbi, zvakatemwa zvekutanga zvinorambidzwa. Zviyero zve zvinoputika nharaunda – General Equipment Zvinodiwa – tsanangura zvinotevera:

Kirasi I

Mukugadzira RPL level MA kana Mb midziyo yemagetsi isina kuputika, kuumbwa kwealuminium, magnesium, titanium, uye zirconium mune zvakavharirwa zvinhu hazvifanirwe kudarika 15% by mass, uye iyo yakasanganiswa misa muzana yetitanium, magnesium, uye zirconium haifaniri kudarika 7.5%.

Kirasi II

YeKirasi II inoputika-inodzivirira kugadzirwa kwemidziyo yemagetsi, huwandu hwehuwandu hwehuwandu hwezvinhu zvakakosha mune zvakavharirwa zvinhu zvinosiyana zvichienderana nedanho rekudzivirira: Ye EPLGa midziyo, iyo yakazara zvinyorwa zvealuminium, magnesium, titanium, uye zirconium haifaniri kudarika 10%, pamwe magnesium, titanium, uye zirconium isingapfuuri 7.5% pamwe chete; Zvemidziyo yeEPLGb, iyo aggregate yemukati ye magnesium uye titanium haifanirwe kudarika 7.5%; Panyaya ye EPLGc midziyo, kunze kwemafani, fan inovhara, uye kufefetera gomba kunokanganisa kusangana neEPLGb zviyero, hapana zvimwe zvinodiwa zvakananga.

Kirasi III

Mukugadzira Kirasi III inoputika-inodzivirira magetsi zvishandiso, iyo inodiwa huwandu hwehuwandu hwezvinhu zvakakosha mumidziyo yakavharirwa zvakare inosiyana nedanho rekudzivirira: Zvemidziyo EPLDa, magnesium uye titanium content haifaniri kudarika 7.5%; Zvemidziyo yeEPLDb, muganhu mumwe chetewo unoshanda; Zvemidziyo yeEPLDc, kunze kwemafani, fan inovhara, uye kufefetera gomba baffles kuomerera kune EPLDb maitiro, hapana zvimwe zvakakosha zvinodiwa.
