I-mechanical seal ayilocandelo le-monolithic; yindibano yobuso obujikelezayo nobumileyo, izinto zokuvala zesibini, kunye ne-hardware yesinyithi. Elinye lala macandelo kufuneka limelane nokusingqongileyo kweekhemikhali ngokwalo ngelixa ligcina ukunyamezelana okuchanekileyo koomatshini phantsi koxinzelelo kunye namaqondo obushushu ahlukeneyo. Ukungaphumeleli ukuhambelana nezixhobo ezichanekileyo ne-fluid chemistry ethile kunciphisa kakhulu i-Mean Time Between Failures (MTBF) kwaye kwandisa umngcipheko wokusebenza.
Ikhemistri yenkqubo, umngcipheko wokuvuza, kunye nempembelelo yexesha lokungasebenzi
Ikhemistri yenkqubo ilawula isantya kunye nendlela yokuwohloka kwezinto. Ulwelo lwemizi-mveliso lunokubonisa amanqanaba e-pH agqithisileyo, ukusuka kwi-acid ephezulu (pH < 1) ukuya kwi-alkaline ephezulu (pH > 13), nganye ihlasela izinto ngokwahlukileyo. Umzekelo, ii-oxidizing acids ezifana ne-nitric acid zinokususa ezinye iintsimbi ezingenasici kodwa zitshabalalise ngokukhawuleza ubuso be-carbon seal eqhelekileyo. Ngaphezu koko, ungcoliseko oluncinci, oluhlala lungajongwa kwiinkcukacha zolwelo olukhulu, lunokusebenza njengee-catalysts zeendlela zokubola ezikwindawo efana nokubola kwe-pitting okanye i-crevice.
Umngcipheko wokuvuza onxulunyaniswa nokukhethwa kwezinto ezingachanekanga udlulela ngaphaya kokusilela nje koomatshini. Kwinkqubo yeekhemikhali kunye nokucocwa kwepetrochemical, iikhompawundi ze-organic eziguquguqukayo (ii-VOC) kunye nongcoliseko lomoya oluyingozi kufuneka zithintelwe ngokungqongqo. Imithetho ye-Environmental Protection Agency (EPA) idla ngokuyalela ukuba ukukhutshwa kwe-pump seal kuhlale kungaphantsi komlinganiselo we-500 parts per million (ppm). Ukwaphuka okubangelwa kukubola ebusweni be-seal okanye ukubola kwe-elastomer kunokubangela ukwaphulwa kwemithetho ngoko nangoko, okubangela ukuvalwa okungxamisekileyo kunye nokukhuthaza ingxelo enyanzelekileyo yokusingqongileyo.
Iindleko zokusilela ezinxulumene nokuhambelana okungekho semgangathweni kwezinto
Iziphumo zemali zokungahambi kakuhle kwezinto zidlula kakhulu iindleko zokuqala zokuthenga isitywina soomatshini ngokwaso. Xa isitywina singaphumeleli ngenxa yokuhlaselwa ngamakhemikhali, iindleko zokutshintshwa ngokuthe ngqo ziyanda ngumsebenzi ofunekayo wokukhupha ipompo, ukucoca, kunye nokufaka kwakhona. Okubaluleke ngakumbi kukuba, iindleko ezingathanga ngqo ezinxulumene nexesha lokungasebenzi elingacwangciswanga zinokuba nzima kakhulu. Kwiindawo zokucubungula ezisebenza ngamandla aphezulu, ukungaphumeleli kwepompo okungalindelekanga kunokumisa umgca wemveliso, kubangele iindleko zexesha lokungasebenzi ukusuka kwi-$10,000 ukuya ngaphezulu kwe-$50,000 ngeyure kuxhomekeke kushishino kunye nexabiso lemveliso.
