Imithetho yanamhlanje yokukhupha ukungcola ifuna ulawulo olungqongqo lokuvuza. Umzekelo,izitywino zoomatshiniEzi zenzelwe imigangatho ye-API 682 zihlala ziyilelwe ukunciphisa ukukhutshwa kwe-volatious organic compound (VOC) ukuya ngaphantsi kwe-500 parts per million (ppm), kunye namazinga aphezulu okuvuza kolwelo avumelekileyo adla ngokulinganiselwa kwi-5.6 grams ngeyure kwizicelo ze-hydrocarbon eziqhelekileyo. Ukugcina ezi mpawu zokuvuza ezincinci yikona okugcina izityalo zokucubungula eziqhubekayo zisebenza ngaphandle kokuphazamiseka komthetho.
Iziphumo zokukhetha isitywina ngendlela engafanelekanga
Ukusilela ukuchaza isitywina se-pump shaft esichanekileyo kubangela uthotho lweziphumo ezibi. Eyona mpembelelo ikhawulezileyo yeyezemali: kwimisebenzi ye-petrochemical enamandla aphezulu okanye yokucoca, ixesha lokungasebenzi kwe-pump elingacwangciswanga linokubangela iindleko eziqala kwi-$10,000 ukuya kwi-$50,000 ngosuku kwimveliso elahlekileyo yodwa.
Ngaphaya kokulahlekelwa yingeniso, ukhetho olungalunganga lubeka emngciphekweni ukhuseleko. Itywina elingakwaziyo ukuphatha ukunyuka koxinzelelo okungalindelekanga okanye iinguqu zobushushu obuphezulu linokuba nokuqhuma kobuso okubi, likhuphe ulwelo oluyingozi, olunokutsha, okanye olunetyhefu emoyeni. Ukongeza, ukhetho olubi lwetywina ludla ngokukhokelela kumonakalo wesinye isixhobo, njengokuxinana okukhulu kweshaft, ukungcola kweebheringi, kunye nokusilela kwemoto ngenxa yokungena kolwelo, okuphinda-phinda iindleko zokulungisa ezisisiseko ngesiqingatha sesithathu ukuya kwesihlanu.
Iziseko zeSeal yePump Shaft kunye neendidi eziphambili
Izitywino zemibhobho yempompo yemizi-mveliso zisebenza ngokomgaqo wokulawula indawo evulekileyo phakathi kombhobho ojikelezayo kunye nebhokisi yempompo engashukumiyo. Nangona injongo ephambili ihlala ingaguquguquki, indlela yoomatshini iyahluka kakhulu ngokusekwe kubukhali bolwelo, izinga lokuvuza elifunekayo, kunye nohlahlo-lwabiwo mali olukhoyo lokugcina izinto. Iindidi ezimbini eziphambili zezokupakisha ucinezelo lwendabuko kunye nezitywino zemishini ezichanekileyo.
Ukupakisha vs izitywino zoomatshini
Ukupakisha okucinezelweyo, okwakwaziwa njenge-gland packing, kusebenzisa izinto ezilukiweyo (ezifana ne-PTFE, i-graphite, okanye i-aramid) ezicinezelweyo ezijikeleze i-shaft ukuze kuthintelwe ukuhamba kolwelo. Kufuna ukuvuza ngabom, okuqhubekayo—ngokuqhelekileyo malunga namaconsi angama-40 ukuya kuma-60 ngomzuzu—ukuthambisa nokupholisa i-shaft. Nangona ukupakisha kunika iindleko zokuthenga eziphantsi kwaye kunokuphinda kupakishwe ngaphandle kokuyichitha ngokupheleleyo ipompo, kusebenzisa amandla okungqubana aphindwe kathandathu kunezinye iindlela.
Izitywino zoomatshini zisebenzisa ubuso obubini obuthe tyaba kakhulu (obunye bujikeleza, obunye bunganyakazi) obucinezelwe kunye kukuxinana kwentwasahlobo kunye noxinzelelo lolwelo. Ifilimu yolwelo oluncinci, oludla ngokuba ngaphantsi kwe-1 micron ubukhulu, yahlula ubuso, nto leyo ebangela ukuvuza okubonakalayo okuphantse kube zero. Nangona utyalo-mali lokuqala luphezulu, izitywino zoomatshini ziyasusa ukuxinana kweshaft kwaye zinciphisa kakhulu ukulahleka kwemveliso.
