NORTECHis imwe yeChina inotungamiraVharuvhu Yepasi Mugadziri & Mutengesi.

Ndezvipi zvakanakira nezvakaipa zvevharuvhu yepasi rose?
Zvikamu zvekuvhura nekuvhara zvevharuvhu rekuvhara zvine mapuranga akafara akaita seplagi, uye nzvimbo yekuvharira yakatsetseka kana kuti yakakombama, uye inofamba yakatwasuka ichitevedza mutsetse wepakati pemvura. Chimiro chekufamba kwetsvimbo chine rudzi rwetsvimbo yekusimudza (tsinde yevharuvhu inosimudzwa uye inodzikiswa, vhiri reruoko harisimuki), uye kune rudzi rwetsvimbo inotenderera yekusimudza (vhiri reruoko netsinde yevharuvhu zvinotenderera uye zvinosimuka pamwe chete, uye nati yakaiswa pamuviri wevharuvhu). Vharuvhu yekumisa inongokodzera kuvhurwa zvizere uye zvakavharwa zvizere, kugadzirisa uye kudhonza hazvibvumirwi.
Vharuvhu yekumisa ivharuvhu yekumanikidza, saka kana vharuvhu yavharwa, kumanikidzwa kunofanira kuiswa paflap kuti kumanikidze pamusoro pekuvhara kuti isadonhe. Kana medium ichipinda muvharuvhu matanhatu kubva pasi pedhisiki yevharuvhu, kuramba kunodiwa nesimba rekushanda ndiko kumanikidzwa kwetsinde yevharuvhu uye kurongedza uye kusundidzirwa kunokonzerwa nekumanikidzwa kwemedium. Simba rekuvhara vharuvhu rakakura kupfuura simba rekuvhura vharuvhu, saka dhayamita yetsvimbo inofanira kunge yakakura, zvikasadaro pombi yekuvharira tsinde yevharuvhu ichakundikana. Mumakore achangopfuura, kubva pakabuda mavharuvhu ekuzvivharira, nzira yepakati yekuyerera kwevharuvhu yakachinja kubva pamusoro pevharuvhu ichipinda muvharuvhu. Panguva ino, pasi pekushanda kwesimba repakati, simba rekuvhara vharuvhu diki, nepo simba rekuvhura vharuvhu rakakura. Dhayamita inogona kuderedzwa zvinoenderana. Panguva imwe chete, pasi pekushanda kwemedium, rudzi urwu rwevharuvhu rwakasimbawo. "Sanhua" yevharuvhu yenyika yangu yakambotaura kuti nzira yekuyerera kwevharuvhu yekumisa inofanira kuva kubva kumusoro kusvika pasi.
Kana vharuvhu yekudzima yavhurwa, kana kukwirira kwekuvhura kwedhisiki kuri 25%-30% yedhayamita yezita, kuyerera kwasvika pakakwirira, zvichiratidza kuti vharuvhu yasvika panzvimbo yakavhurika zvizere. Saka, nzvimbo yakavhurika zvizere yevharuvhu yekudzima inofanira kutsanangurwa nekurovera kwedhisiki yevharuvhu.
Vharuvhu yekumisa inogona kukamurwa kuita: vharuvhu yekumisa, vharuvhu yekumisa yetsinga yepamusoro, vharuvhu yekumisa yetsinga yepasi, vharuvhu yekumisa yakatwasuka, vharuvhu yekumisa yekona, vharuvhu yekumisa ine nzira nhatu, vharuvhu yekumisa yakananga, vharuvhu yekumisa yeplunger, vharuvhu yeglobhu yakaumbwa neneedle Shaped.
Zvakanakira: chimiro chiri nyore, kugadzira nekugadzirisa zviri nyore.
Kushanda kwemuchina kudiki, uye nguva yekuvhura nekuvhara ipfupi.
Kushanda zvakanaka kwekuvhara, kukweshana kudiki pakati penzvimbo dzekuvhara, uye kugara kwenguva refu.
Zvakashata:
Kuramba kwemvura kwakawanda, uye simba rinodiwa pakuvhura nekuvhara rakakura.
Hazvina kukodzera kushandiswa kwemidziyo ine zvidimbu, viscosity yakanyanya uye coke iri nyore kushandisa.
Kusashanda zvakanaka kwekugadzirisa
Kuchenjerera pakuisa nekugadzirisa: Vharuvhu yekumisa inoshandiswa nevhiri reruoko nemubato inogona kuiswa chero panzvimbo yepombi.
Mavhiri emaoko, mahandle uye mashandiro anochinja-chinja hazvitenderwi kushandiswa pakusimudza. Nzira yekuyerera kwechinhu ichi inofanira kuenderana nekwakananga museve unoratidzwa pavharuvhu.
