Kamuri rakachena rine mitemo yakasimba pamusoro pekupisa kwezvakatipoteredza, hunyoro, huwandu hwemhepo itsva, kuvheneka, nezvimwewo, zvichiita kuti zvigadzirwa zvive zvakanaka uye kuti nzvimbo yekushanda yevashandi igare zvakanaka. Sisitimu yese yekamuri rakachena ine sisitimu yekuchenesa mweya ine matanho matatu ichishandisa mafirita ekutanga, epakati uye ehepa kudzora huwandu hwezvimedu zveguruva uye huwandu hwemabhakitiriya e sedimentation uye mabhakitiriya anoyangarara munzvimbo yakachena. Sefa yehepa inoshanda sechishandiso chekusefa terminal chekamuri rakachena. Sefa iyi inosarudza mashandiro ehurongwa hwese hwekamuri rakachena, saka zvakakosha kunzwisisa nguva yekutsiva sefa yehepa.
Nezvemitemo yekutsiva mafirita ehepa, pfungwa dzinotevera dzakapfupikiswa:
Kutanga, ngatitangei nefirita yehepa. Mukamuri rakachena, kungave firita yehepa yakakura yakaiswa pamucheto weunit yekutonhodza mhepo inochenesa kana firita yehepa yakaiswa pabhokisi rehepa, izvi zvinofanirwa kunge zvine marekodhi enguva yekushanda akarurama, kuchena uye huwandu hwemhepo zvinoshandiswa sehwaro hwekutsiva. Semuenzaniso, kana uchishandiswa zvakajairika, hupenyu hwesefa yehepa hunogona kupfuura gore rimwe. Kana dziviriro yepamberi ikaitwa zvakanaka, hupenyu hwesefa yehepa hunogona kureba sezvinobvira. Hapazovi nedambudziko zvachose kwemakore anopfuura maviri. Ehe, izvi zvinoenderanawo nemhando yefirita yehepa, uye inogona kunge yakareba;
Chechipiri, kana firita yehepa yakaiswa mumidziyo yakachena yemukamuri, senge firita yehepa mushawa yemhepo, kana firita yekutanga yepamberi yakachengetedzwa zvakanaka, hupenyu hwesefa yehepa hunogona kusvika makore anopfuura maviri; sekuchenesa firita yehepa patafura, tinogona kutsiva firita yehepa kuburikidza nekukurudzira kwegeji yekumanikidza pabhenji rakachena. Kune firita yehepa iri palaminar flow hood, tinogona kuona nguva yakanakisa yekutsiva firita yehepa nekuona kumhanya kwemhepo kwefirita yehepa. Nguva yakanakisa, senge kutsiva firita yehepa pafani yefirita, ndeyekutsiva firita yehepa kuburikidza nekukurudzira muPLC control system kana kukurudzira kubva ku pressure gauge.
Chechitatu, vamwe vevagadziri vedu vemafirita emhepo vane ruzivo vakapfupikisa ruzivo rwavo rwakakosha uye vachakuzivisai pano. Tinovimba kuti zvinogona kukubatsirai kunzwisisa nguva yakanakisa yekutsiva firita yehepa. Chiyero chekumanikidza chinoratidza kuti kana resistance yehepa filter yasvika kaviri kusvika katatu yekuramba kwekutanga, kugadzirisa kunofanira kumira kana kuti firita yehepa inofanira kutsiviwa.
Kana pasina pressure gauge, unogona kuona kana ichida kutsiviwa zvichibva pane zvinotevera zviri nyore zvine zvikamu zviviri:
1) Tarisa ruvara rwechinhu chinosefa chiri kumativi ekumusoro neapasi pechinhu chinosefa chehepa. Kana ruvara rwechinhu chinosefa chiri parutivi rwemhepo rwukatanga kuita dema, gadzirira kuchitsiva;
2) Bata chinhu chinosefa chiri pamusoro pemhepo inobuda musefa yehepa nemaoko ako. Kana paine guruva rakawanda pamaoko ako, gadzirira kuchitsiva;
3) Nyora mamiriro ekutsiva hepa filter kakawanda uye tsanangura kutenderera kwakakodzera kwekutsiva;
4) Zvichienderana nepfungwa yekuti hepa filter haisati yasvika padanho rekupedzisira, kana musiyano wekumanikidzwa pakati pekamuri rakachena nekamuri riri pedyo ukadonha zvakanyanya, zvinogona kunge kuti kuramba kwekusefa kwekutanga nekwepakati kwakakura zvakanyanya, uye zvakakosha kugadzirira kutsiva;
5) Kana kuchena muimba yakachena kukasaenderana nezvinodiwa zvemagadzirirwo, kana paine kumanikidzwa kwakashata, uye nguva yekutsiva mafirita ekutanga nepakati isati yasvika, zvinogona kunge kuti kuramba kwefirita yehepa kwakakura zvakanyanya, uye zvakakosha kugadzirira kutsiva.
Pfupiso: Mukushandiswa kwakajairika, mafirita ehepa anofanira kutsiviwa makore maviri kusvika matatu ega ega, asi data iri rinosiyana zvikuru. Data rechokwadi rinogona kuwanikwa chete muchirongwa chakati, uye mushure mekusimbiswa kwekushanda kwekamuri rakachena, data rechokwadi rakakodzera imba yakachena rinogona kupihwa chete kuti rishandiswe mushawa yemhepo yekamuri rakachena iroro.
Kana chiyero chekushandisa chikawedzerwa, kuchinja kwenguva yehupenyu hakudzivisiki. Semuenzaniso, mafirita ehepa ari mumakamuri akachena akadai semaworkshop ekurongedza chikafu nema laboratori akaedzwa uye akatsiviwa, uye hupenyu hwebasa hunopfuura makore matatu.
Saka, kukosha kwehupenyu hwesefa hakugone kuwedzerwa nemaune. Kana dhizaini yesystem yekamuri rakachena isina musoro, kurapwa kwemhepo itsva kusina kuitwa, uye chirongwa chekudzora guruva reshawa remukamuri rakachena chisina kuenderana nesainzi, hupenyu hwesefa yehepa huchava hupfupi zvechokwadi, uye imwe ingatofanira kutsiviwa mushure menguva isingasviki gore rekushandiswa.
