(1) Kakiwikāʻaʻole hana.
ʻO ke kumu o ka hewa a me nā kumu penei:
1. ʻAʻohe kumu o ke kinoea.① ʻAʻole i wehe ʻia ke kumu ea, ② ma muli o ka nui o ka wai o ka hau kumu ea i ka hoʻoilo, ka hopena i ka hoʻopaʻa ʻana o ka ea a i ʻole ka kānana, ka hoʻopaʻa ʻana i ka pahu hoʻomaha hoʻomaha, ③ hāʻule ka mea hoʻoheheʻe ea, ④ ea kumu nui paipu leakage.
2. Puna ea, ʻaʻohe hōʻailona.① DCS hoʻopuka hewa, ② hōʻailona uwea keakea; ③ ʻimi hewa;
3. ʻAʻohe kumu kinoea o ka mea ʻimi. ② hiki ʻole ke kaomi ʻana i ka valve ③ ka leaka a i ʻole ka hoʻopaʻa ʻana.
4. He kumu kinoea ko ka positioner a ʻaʻohe puka. Ua ālai ʻia ka nozzle.
5. Hōʻailona, ʻaʻohe hana.① Paʻa ke kumu a me ka noho, ② piʻo a haki paha ke kumu; ③ ka lepo paʻa a i ʻole ka coke block; ④ mea hoʻoheheʻe puna wai ma muli o ka hoʻohana lōʻihi; ⑤ haʻi ka puna puna a i ʻole ka diaphragm; ⑥ solenoid valve hemahema; ⑦ paʻa ke kumu.
(2) ʻAʻole paʻa ka hana o ka valve.
ʻO ke kumu o ka hewa a me nā kumu penei:
1. Paʻa paʻa ʻole o ke kumu ea. ʻAʻole hiki ke hoʻopau ʻia ka pahu hoʻomaha.
2. ʻAʻole paʻa ke kaomi o ka hōʻailona.① Nā ʻāpana PID o ka helu mana; ② ʻAʻole paʻa ka puka hoʻoponopono; ③ wehe ʻia nā uwea.
3. Paʻa ke kaomi kumu ea, a paʻa pū ke kaomi hōʻailona, akā ʻaʻole paʻa ka hana o ka valve hoʻoponopono.① Loaʻa ka hewa; ② paipu puka a me ka leak laina; ③ ʻoʻoleʻa loa ka mea hana; ke kū'ē kū'ē nui i ka neʻe ʻana o ke kumu ④; ⑤ ʻaʻole paʻa ke kūlana hana, ʻaʻole kūlike ke kūlana o kēia manawa i ke koho; ⑥ haʻihaʻi ka diaphragm a i ʻole ka puna; ⑦ ke kahe ana o ka cylinder a i ʻole ke poʻo membrane; ⑧ pōʻino o loko o ka valve; ⑨ ʻAʻole paʻa ke kiko ana.
(3) Haʻalulu kiwi.
ʻO ke kumu o ka hewa a me nā kumu penei:
1. Haʻalulu ka valve hoʻoponopono i kekahi degere wehe.① Kākoʻo paʻa ʻole; kumu haʻalulu kokoke i ②; ③ spool a me ka nahele; ʻoi loa ka throttling.
2. ʻO ka valve hoʻoponopono e haʻalulu kokoke i ke kūlana pani piha.① Nui ka valve hoʻoponopono a hoʻohana pinepineʻia ma lalo o ka puka liʻiliʻi; ② ʻAʻole kūpono ka valve noho hoʻokahi no nā kūlana hana.
(4) He lohi ka hana o ka valve.
ʻO ke ʻano a me nā kumu o ka puʻuwai penei:
Puulehu ke kumu o ka valve i ka manawa o ka hana reciprocating.① Paʻa paʻa i loko o ka valve; ② PTFE packing deterioration hardening a graphite packing lubricating aila maloʻo; ③ paʻa loa ka paʻi ʻana, piʻi ke kūʻē i ka friction; ④ ʻaʻole pololei ka pale ʻana i ka friction ma muli o ke kumu valve; ⑤ ʻaʻole lawa ka ikaika o ka pahu, nā pilikia kumu a i ʻole ke kinoea; ⑥ hoʻololi i ke kūlana hana; ⑦ puna hewa; ⑧ hāʻule ka mea huli.
(5) Hoʻonui ka leakage o ka valve.
ʻO nā kumu o ka leakage penei:
1. Nui ka leakage i ka wā e pani pono ai ka valve. ③ ʻaʻole i hoʻoponopono ʻia ka mechanical zero.
2. ʻAʻole hiki i ka valve ke hiki i ke kūlana paʻa paʻa.① ʻO ka ʻokoʻa ʻokoʻa ma waena o ka ʻokoʻa, ʻoi aku ka liʻiliʻi o ka torque actuator, ʻaʻole lawa ke kaomi kumu ea, ʻaʻole i pani ʻia ka valve; aia nā mea ʻē i ka ② valve; ʻo ka ③ bushing e coking; ua poino ka loko o ④ valve.
(6) ʻOi aku ka liʻiliʻi o ka laulā hiki ke hoʻololi.
kumu waiwai: ʻOi aku ka liʻiliʻi o ke kumu valve a i ʻole ka noho valve, no laila e nui aʻe ka puka maʻamau.
