A. Kugadzirisa sefa yemhepo
a.Iyo sefa element inofanira kuchengetedzwa kamwe pasvondo.Bvisa iyo sefa chinhu, uye wobva washandisa iyo 0.2 kusvika 0.4Mpa mweya wakatsikirirwa kupeperetsa guruva riri pamusoro pesefa.Shandisa jira rakachena kupukuta tsvina iri pamadziro emukati mesefa yemhepo.Mushure meizvozvo, isa iyo sefa element.Paunenge uchiisa, mhete yekuisa chisimbiso inofanira kunyatsoenderana nemhepo sefa imba.
b.Kazhinji, iyo sefa chinhu chinofanira kutsiviwa pa1,000 kusvika 1,500 maawa.Kana yaiswa kunharaunda ine hutsinye, yakadai semigodhi, fekitori yekeramiki, chigayo chekotoni, nezvimwewo, inokurudzirwa kutsiviwa pamaawa mazana mashanu.
c.Paunenge uchichenesa kana kutsiva iyo sefa chinhu, dzivirira nyaya dzekunze kupinda muvharuvhu inopinza.
d.Iwe unofanirwa kugara uchiongorora kana paine chero kukuvara kana deformation yekuwedzera pombi.Zvakare, iwe unofanirwa kutarisa kuti mubatanidzwa wakasununguka here kana kwete.Kana paine dambudziko rataurwa pamusoro apa riripo, saka unofanirwa kugadzirisa nenguva kana kutsiva izvo zvikamu.
B. Oiri Sefa Kutsiva
a.Iwe unofanirwa kushandura sefa itsva yemafuta neiyo yakatsaurirwa wrench, yemhepo itsva compressor iyo yakashandiswa kwemaawa mazana mashanu.Isati yaiswa sefa itsva, zviri nani kuwedzera mafuta ekukurisa, wobva wakoromora chibatiso neruoko kuti uname sefa chinhu.
b.Zvinokurudzirwa kuti iyo sefa element inofanira kutsiviwa pa1,500 kusvika 2,000 maawa.Paunoshandura oiri yeinjini, iwe unofanirwawo kushandura iyo sefa chinhu.Iyo yekutsiva kutenderera kunofanirwa kupfupikiswa, kana iyo mhepo sefa yakashandiswa munzvimbo yakaoma yekushandisa.
c.Iyo sefa element inorambidzwa kushandiswa kwenguva yakareba kupfuura hupenyu hwayo hwesevhisi.Zvikasadaro, ichavharwa zvakakomba.Iyo bypass valve inozovhurika otomatiki kana iyo yekusiyanisa kudzvanywa kwapfuura iyo yakanyanya kutakura simba revhavha.Pasi pemamiriro ezvinhu akadaro, tsvina ichapinda mujini pamwe chete nemafuta, zvichikonzera kukanganisa kwakanyanya.
C. Air Oil Separator Replacement
a.Muparadzi wemafuta emhepo anobvisa mafuta ekuzora kubva mumhepo yakamanikidzwa.Pasi pekushanda kwakajairwa, hupenyu hwayo hwesevhisi ndeye 3,000 maawa kana zvakadaro, izvo zvinozopesvedzerwa nemafuta ekuzora mhando uye kusefa kunaka.Munzvimbo inosemesa yekushandisa, kutenderera kwekuchengetedza kunofanirwa kupfupikiswa.Uyezve, pre air sefa inogona kudiwa kuti ive nechokwadi chekushanda kwakajairika kwemhepo compressor mune yakadaro.
b.Kana iyo mhepo inoparadzanisa mafuta yemhepo yakafanira kana kuti mutsauko wekudzvanya uchipfuura 0.12Mpa, iwe unofanirwa kutsiva iyo yekuparadzanisa.
