3.1.2Nā kumu o ka varnish

* ʻO ka aila lubricating mineral ka nui o nā hydrocarbons, kahi paʻa i ka lumi wela a me ka wela haʻahaʻa.Akā inā ma ke ʻano o ka wela kiʻekiʻe, ʻo kekahi (ʻoiai he liʻiliʻi loa ka helu) nā molekala hydrocarbon e hana i ka hopena oxidation, e hahai pū kekahi mau molekala hydrocarbon i ke kaulahao, ʻo ia ke ʻano o ka hopena o ke kaulahao hydrocarbon;

* Hoʻokumu ka ʻaila lubricate i ka soluble varnish i ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe.I ke kaʻina hana o ka aila kahe mai ka kiʻekiʻe wela wahi a hiki i ka haʻahaʻa wela wahi, ka wela emi e alakai i ka emi o ka solubility, a me ka varnish particles precipitate mai ka lubricating aila a hoʻomaka e waiho;

* Hoʻokomo ʻia ka varnish.Ma hope o ka hoʻokumu ʻia ʻana o nā ʻāpana varnish, hoʻomaka ka sediment e condense a hana i ka sediment e makemake ʻia e waiho ʻia ma luna o ka ʻili metala wela, e hopena i ka piʻi ʻana o ka wela o ka ulu lāʻau i hope e piʻi mālie ka mahana o ka aila;

* Hiki ke hoʻololi ʻia e nā kumu kaiapuni ʻē aʻe a i ʻole nā ​​pilikia hewa o ka ʻāpana.

3.2.4 Ke kumu hana o ka ʻenehana adsorption resin ion —— Wehe i ka varnish hemo

Hiki i ka Ion exchange resin DICR ™ ke wehe i nā mea hoʻoheheʻe i loko o ka aila turbine, e hōʻoia ana i ka emi ʻana o nā hōʻailona MPC, no ka mea hiki ke hoʻoheheʻe ʻia ka hapa nui o nā turbines i ka wā o ka hana, a hoʻopiha wale kēia mau huahana i ka ua, ʻaʻole hiki i nā lako electrostatic ke wehe i kēia mau huahana i loko. ka mokuʻāina i hoʻoheheʻe ʻia.

ʻO ka hui pū ʻana o ka electrostatic adsorption a me ka ʻenehana resin ʻaʻole hiki ke wehe wale i ka varnish i hoʻokuʻu ʻia, akā hoʻopau pū i ka huahana varnish dissolved.

3.3 Ka hopena o ka wehe ʻana i ka varnish

Ma Dekemaba 14,2019, ua hoʻokomo ʻia ka kānana aila varnish model WVD a hoʻohana ʻia.Ma lalo o ke ana piha o ka hoʻololi ʻana i ka aila ʻaila turbine hau ma ʻAukake 20,2020, ua emi ka mahana o ka turbine bearing (bush) mai 108 ℃ a ma kahi o 90 ℃ (e nānā i ke kiʻi 6 ke ʻano wela o ka hoʻomaʻemaʻe hoʻomaʻemaʻe hope (nahele)).Hoʻomaikaʻi maikaʻi ʻia ke kala o ka aila (Figure 7 hoʻohālikelike o ka ʻaila ma mua a ma hope o ka hoʻomaʻemaʻe ʻana).Ma o ka ʻikepili a me ka ʻikepili hoʻāʻo waho, ua hoʻemi ʻia ka tendency index o ka ʻaila varnish mai 42.4 a i 4.5, ua hoʻemi ʻia ka pae pollution mai NAS 9 a i 6, a ua hoʻemi ʻia ka helu waiwai waika mai 0.17 a i 0.07. (E nānā i ka Papa 6 Test a ka hopena o ka ʻaila ma hope o ke kānana kānana)
