Manual turbine bhora mavharuvhu anoshandiswa zvakanyanya mumaindasitiri akawanda, anosanganisira makemikari, peturu, gasi rechisikigo, simbi, kugadzira mapepa, uye mishonga. Zvavo chimiro chakareruka, kuita kwakanakisa chisimbiso, hupenyu hurefu hwebasa, uye nyore kugadzirisa vagadzire midziyo yakakosha yekudzora kuyerera kwenhau mumapaipi masisitimu. Sechinhu chakakosha chebhurabhu yebhurabhu yebhurawuza, iyo kuisa chisimbiso kweiyo gearbox inokanganisa zvakananga kushanda kwayo uye hupenyu hwebasa. Naizvozvo, kuvandudza kuita kwekuvharisa kweiyo gearbox uye kuwedzera nguva yekuigadzirisa kune zvakakosha zvikuru.

Pneumatic bhora mavharuvhu ari kuwedzera kushandiswa mune zvemazuva ano maindasitiri otomatiki ekudzora masisitimu, uye kukurumidza uye kwakaringana mhinduro kuita kwakakosha pakuona kwakagadzikana mashandiro ehurongwa.

Nekuda kwenzvimbo yayo yakasarudzika yekushanda, iyo petrochemical indasitiri inoisa zvakanyanya kudiwa pakuchengetedza michina. Sechikamu chakakosha chekudzora kuyerera kwemvura munzvimbo dzinogona kuputika, kuputika-uchapupu mavharuvhu ebhora remagetsi zvinoda ATEX chitupa, chiyero chakakosha chekuchengetedza.

Munzvimbo dzinopisa zvikuru dzemaindasitiri, mavharuvhu akaoma-chidhindo ebhora ari kushanda pamusoro pe800°C anoita basa rakakosha. Kuve nechokwadi chekuvimbika kwavo uye kuisa chisimbiso kuita pasi pemamiriro akanyanya, innovative thermal deformation compensation structures dzakanyanya kukosha.

Mundima yeindasitiri, imwe-chidimbu welded bhora mavharuvhu, inozivikanwawo se zvizere welded bhora mavharuvhu, anoshandiswa zvakanyanya mumapaipi masisitimu mumaindasitiri mazhinji, kusanganisira petroleum, makemikari, gasi rechisikigo, uye kudziyisa, nekuda kwekuita kwavo kwechisimbiso kwakanakisa uye kuramba kudzvinyirira kwakanyanya uye kupisa kwakanyanya.

Asidhi yakasimba uye alkalis anoshandiswa zvakanyanya muminda yakawanda yemaindasitiri, senge petrochemicals, simbi, uye mishonga. Izvi zvinoodza media zvinoisa zvakanyanya kudiwa pamidziyo.

Fluorine-lined corrosion-resistant ball valves, semugadziri wevharuvhu yehunyanzvi, yave sarudzo yakavimbika kumakambani mazhinji nekuda kwekushomeka kwavo kwakanakisa.

Mumaindasitiri akadai makemikari uye electroplating, fluorine-lined anti-corrosion bhora mavharuvhu vanofarirwa zvakanyanya nekuda kwekusagadzikana kwavo kwecorrosion.

PTFE (polytetrafluoroethylene) lining inoita basa rakakosha mu kuwedzera hupenyu hwechisimbiso zvemavharuvhu ebhora.

Mumakore achangopfuura, nyika yangu mitemo yekuchengetedza kwezvakatipoteredza zvawedzera kuomesera, uye kudiwa kwezvinhu zvine hushamwari zvakatipoteredza kuri kuramba kuchikwira mumaindasitiri akasiyana siyana. Muindasitiri yevharuvhu, PE epurasitiki bhora mavharuvhu, sorudzi rutsva rwevharuvhu inoshamwaridzana nemhoteredzo, zvishoma nezvishoma yakakwezva kutarisisa kwakapararira.

Mumadiridziro emazuva ano ekurimisa. PE epurasitiki bhora mavharuvhu vari kuramba vachikurumbira nekuda kwehuremu hwavo hwakasiyana uye makemikari kuramba. Chinyorwa ichi chichaongorora zvakanakira PE epurasitiki bhora mavharuvhu mumadiridziro ekurima uye kuti zvivakwa izvi zvingakwidzirwe sei kuti zvivandudze kuita kwemadiridziro uye goho rezvirimwa.

Mumunda weinjiniya yegungwa, kusarudzwa kwemavharuvhu kwakakosha, pakati peiyo 316 simbi isina simbi bhora mavharuvhu uye 304 Stainless simbi bhora mavharuvhu sarudzo dzakajairika. Zvisinei, kuora kweaya mavharuvhu ebhora resimbi isina tsvina nehuwandu hwakawanda hwekloridi ion munharaunda yegungwa idambudziko rakakura, iro rinokanganisa kushanda uye hupenyu hwebasa remavharuvhu, uye kunyange kutyisidzira kushanda kwakachengeteka uye kwakadzikama kweiyo yese marine engineering system. Ngatikurukurei zvakadzama mamiriro emavharuvhu maviri esimbi asina tsvina munzvimbo yegungwa uye mhinduro yekudzivirira chloride ion corrosion.
