1. Matanho ekuchenesa ekubvisa vharafu:
Zvikamu zvakasvibiswa zvevhavha zvinofanira kurapwa nenzira inotevera isati yasangana:
(1) Zvinoenderana nezvinodiwa zvekugadzirisa, zvimwe zvikamu zvevharuvhu zvinoda kukwenenzverwa pasina machining burrs pamusoro;
(2) Degreisa zvikamu zvese zvevharuvhu;
(3) Pickling uye passivation ichaitwa mushure mekudzikisa (mumiririri wekuchenesa haana phosphorus);
(4) Mushure mekunhonga uye passivation, sukurudza nemvura yakanatswa pasina reagent yakasara (iyi nhanho inosiiwa kune kabhoni simbi zvikamu);
(5) Chikamu chevharuvhu chega chega chichapukutwa chakaoma nejira risiri rakarukwa, uye pamusoro pezvikamu zvakaita sewaya yeshinda hazvichengetwe, kana kupeperetswa nenitrogen yakachena;
(6) Pukuta chikamu chevharuvhu yega yega nejira risiri rakarukwa kana pepa resefa rakanatswa nedoro rekuongorora kusvika pasisina ruvara.
2. Assembly zvinodiwa kuti degreasing mavharuvhu
Zvikamu zvakacheneswa zvevhavha yekudzikisa zvinofanirwa kuvharwa uye kuchengetwa kuti zvigadzirwe. Zvinodiwa pakugadzwa kwacho ndeizvi:
(1) Iyo degreasing valve installation workshop inofanira kunge yakachena, kana nzvimbo yakachena kwenguva pfupi (senge ichangobva kutengwa ruvara rwejira rejira kana firimu repurasitiki) inofanira kuvakwa kudzivirira guruva kupinda panguva yekuisa valve.
(2) Vashandi vegungano vanofanira kupfeka mahovhorosi edonje akachena, ngowani dzedonje dzakachena, dzisina kubuda bvudzi, shangu dzakachena uye magurovhosi epurasitiki (kubvisa mafuta).
(3) Zvishandiso zvegungano zvinofanirwa kucheneswa uye kucheneswa pamberi peiyo degreasing valve assembly kuti ive nehutsanana.
