Ihe mmetụta ọsọ/nrụgide: vortex flowmeter, thermal mass flowmeter (ntụgharị nha), onye na-ebugharị nrụgide (nrụgide nha), ejiri gbakọọ ike ọkụ ọkụ.
• Onye njikwa:
Sistemu PLC ma ọ bụ DCS: PID algọridim jikọtara ọnụ, na-agbanwe ike kpo oku na-akpaghị aka dabere na okpomoku setịpụrụ (dịka site na thyristor power regulator ma ọ bụ SSR siri ike relay steeti), na-akwado nleba anya anya na ndekọ data.
2. Igwe njikwa eletriki
• Sistemu ike:
◦ Ntinye ike ntinye: AC 380V/220V,50Hz,Hazie ihe mgbawa sekit na ihe nchekwa ọgbaghara iji kwado ọkụ n'usoro n'usoro atọ.
Njikwa ike: Mgbasa ozi steeti siri ike (SSR) ma ọ bụ onye na-achịkwa ike, mgbanwe na-enweghị kọntaktị, ọsọ nzaghachi ngwa ngwa, ogologo ndụ.
• Ngwa nchekwa nchekwa:
Nchedo oke okpomọkụ: Ejiri ya na igwe ọkụ ọkụ bimetallic arụnyere arụnyere ma ọ bụ ngbanwe okpomọkụ, mgbe ọ̀tụ̀tụ̀ ọkụ a tụrụ atụ̀ gafere uru echere (dị ka 20 ℃ dị elu karịa okpomọkụ a na-achọsi ike), a na-ebipụ ọkụ ọkụ n'ike ma kpalite mkpu.
Nchedo sekit na-agafe agafe / dị mkpụmkpụ: ihe ngbanwe dị ugbu a + ihe na-agbaji okirikiri iji gbochie mmebi sekit na-akpata site na mmejọ tube kpo oku.
Nchedo nrụgide: A na-ejikọta ngbanwe nrụgide na-emechi ka ọ ghara igbochi pipeline overpressure (kpaliri mgbe ọ karịrị 1.1 ugboro nrụgide nhazi).
