A. Kugadzirisa sefa yemhepo
a. Chinhu chinosefa chinofanira kuchengetedzwa kamwe chete pasvondo. Bvisa chinhu chinosefa, wobva washandisa mweya wakamanikidzwa we0.2 kusvika 0.4Mpa kuti ubvise guruva riri pamusoro pechinhu chinosefa. Shandisa jira rakachena kupukuta tsvina iri pamadziro emukati meganda refirita remhepo. Mushure meizvozvo, isa chinhu chinosefa. Paunenge uchiisa, rin'i yekuvhara inofanira kunge yakanyatsokwana pamubhedha wefirita yemhepo.
b. Kazhinji, chinhu chesefa chinofanira kutsiviwa pamaawa chiuru kusvika chiuru nemazana mashanu. Kana chikashandiswa munzvimbo dzine utsinye, dzakadai semigodhi, fekitori yeceramics, muchina wedonje, nezvimwewo, zvinokurudzirwa kutsiviwa pamaawa mazana mashanu.
c. Paunenge uchichenesa kana kutsiva chinhu chinosefa, dzivisa zvinhu zvisina kunaka kuti zvipinde muvharuvhu inopinza mvura.
d. Unofanira kugara uchiongorora kana paine kukuvara kana kushanduka kwepombi yekutambanudza. Zvakare, unofanirwa kutarisa kana joini yacho yakasununguka kana kwete. Kana paine dambudziko rataurwa pamusoro apa, saka unofanirwa kugadzirisa kana kutsiva zvikamu izvozvo nenguva.
B. Kutsiva Sefa yeOiri
a. Unofanira kuchinja firita itsva yemafuta uchishandisa chipanera chakatsaurirwa, chemhepo itsva compressor yave ichishanda kwemaawa mazana mashanu. Usati waisa firita itsva, zviri nani kuwedzera mafuta escrew, wobva wasunga chibatiso neruoko kuti chivhare chinhu chefilter.
b. Zvinokurudzirwa kuti chinhu chefirita chifanirwe kutsiviwa mumaawa 1,500 kusvika 2,000. Paunochinja oiri yeinjini, unofanirawo kuchinja chinhu chefirita. Kuchinja kwemhepo kunofanira kupfupikiswa, kana firita yemhepo ikashandiswa munzvimbo yakaoma yekushandisa.
c. Chinhu chekusefa hachibvumirwi kushandiswa kwenguva yakareba kupfuura nguva yachinoshanda. Zvikasadaro, chichavharika zvakanyanya. Vharuvhu yekufambisa inozovhurika yega kana kumanikidzwa kwedhizaini kwapfuura simba repamusoro revharuvhu. Kana zvadai, tsvina inopinda muinjini pamwe chete nemafuta, zvichikonzera kukuvara kukuru.
C. Kutsiva Chinoparadzanisa Mafuta Emhepo
a. Chinoparadzanisa mafuta emhepo chinobvisa mafuta ekuzora mumhepo yakamanikidzwa. Mukushanda kwakajairika, hupenyu hwayo hwekushanda hunosvika maawa zviuru zvitatu kana kupfuura, izvo zvinokanganiswa nehunhu hwemafuta ekuzora uye kunaka kwefirita. Munzvimbo isingafadzi yekushandisa, kutenderera kwekuchengetedza kunofanirwa kupfupikiswa. Uyezve, firita yemhepo inogona kudiwa kuti ive nechokwadi chekuti compressor yemhepo inoshanda zvakanaka kana zvakadaro.
b. Kana chivhariso chemafuta emhepo chapera kana kuti kumanikidzwa kwedhigirii kwapfuura 0.12Mpa, unofanira kutsiva chivhariso.
