Zvidziyo zvechiller zvinogona kukamurwa kuita zvidziyo zvechiller zvinotonhodzwa nemhepo uye zvidziyo zvechiller zvinotonhodzwa nemvura zvichienderana nenzira dzakasiyana dzekubvisa kupisa. Chidziyo chechiller chinotonhodzwa nemvura chinoshandisa sisitimu yekutenderera kwemvura yetower yekutonhodza kuti chibvise kupisa, nepo chidziyo chechiller chinotonhodzwa nemhepo chinoshandisa mweya wakapfava kuti chibvise kupisa. Munguva yekushanda kweyuniti, pachava nekusvibiswa kunokonzerwa nemhando yemvura kana matambudziko emhepo, kana nekuti mafuta emufiriji ane turbid, izvo zvinokanganisa sisitimu yese yekutonhodza. Ita basa rekuchenesa nekugadzirisa.
Saka, nzira yekuchenesa system yekutonhodza ye screw chiller?
1. Ungaziva sei kuti sisitimu yekutonhodza ye screw chiller inofanira kucheneswa?
Chekutanga, tinofanira kuona kana ruvara rwemafuta e compressor refrigeration oil ye screw chiller rwuchichinja ruvara rwebrown? Kana zvakadaro, zvinoreva kuti mhando yemafuta haina makore. Chechipiri, tarisa kana kunhuhwirira kwatsva, uye tarisa kukosha kwe resistance ye motor winding mu compressor. Kana resistance value iri pakati pe winding ne shell iri yakajairika, zvinoreva kuti insulation yakanaka. Zvikasadaro, mafuta e refrigeration anofanira kutsiviwa uye refrigeration system inofanira kucheneswa.
Pano, ndinoda kuyeuchidza munhu wese: Mumvura yemuchina wekutonhodza, tsvina inonamira pamadziro emukati mepombi zvishoma kana zvishoma. Kana mudziyo ukashanda kwenguva yakareba uye paine tsvina yakawanda, firita yekuomesa ichavharika uye mudziyo hauzokwanisi kutonhora. Saka, zvinokurudzirwa kuchenesa heat exchanger mwedzi mitanhatu yega yega uye kuchenesa system gore rega rega.
2. Chii chinofanira kuitwa tisati tachenesa sisitimu yekutonhodza?
Kana paine kusvibiswa kuri mupombi yefiriji, mushonga wekuchenesa unogona kushandiswa kuuchenesa. Usati wachenesa, zvinodikanwa kusunungura firiji iri mupombi yefiriji, wobva wabvisa compressor, wodurura mafuta efiriji kubva mupombi yekuchenesa. Munguva yekuchenesa, tanga wabvisa compressor nefiriji yakaoma, wobva wabvisa capillary (kana expansion valve) kubva mu evaporator, batanidza evaporator ne condenser nehosi inodzivirira kumanikidzwa, wobva washandisa A hose batanidza zvakasimba michina yekuchenesa nemapombi ekusveta nekuburitsa ecompressor. Wobva wachenesa michina inoshandiswa, senge mapombi, matangi, mafirita, ma dryer, nemavharuvhu akasiyana-siyana.
Maitiro ekuchenesa ndeekuti: tanga waisa mushonga wekuchenesa mutangi remvura, wobva watanga pombi, woita kuti ishande, wotanga kuchenesa. Pakuchenesa, ita mabasa akawanda uchitungamira nekumashure kusvika mushonga wekuchenesa waratidza acidity. Kana paine kusvibiswa kudiki, unongoda kutenderera kweinenge awa imwe chete. Kana paine kusvibiswa kwakanyanya, zvinotora maawa 3-4. Kana ukanyatsocheneswa kwenguva yakareba, mushonga wekuchenesa wakasviba, uye firita yakavharwawo uye yakasviba. Mushonga wekuchenesa nefirita zvinofanirwa kutsiviwa usati waita basa iri. Mushure mekunge sisitimu yacheneswa, mushonga wekuchenesa wakasviba uye firita yakavharwawo uye yakasviba. Mushonga wekuchenesa uri mudura remvura unofanira kutorwa kubva mupombi yemvura. Mushure mekuchenesa, nitrogen inoputirwa nekuomeswa inofanira kuitwa papombi yekutonhodza, uye yozozadzwa nefluorine, uye basa rekugadzirisa unit rinofanira kuitwa kuti chiller ishande zvakanaka.
Simba remuchina wekutonhodza screw rakakura, uye pane sarudzo yemusoro mumwe chete kana miviri. Muchina wekutonhodza screw une musoro mumwe chete une compressor imwe chete, inogona kugadziriswa muzvikamu zvina kubva pa100% kusvika 75% kusvika 50% kusvika 25%. Muchina wekutonhodza screw une miviri miviri une macompressor maviri uye une masisitimu maviri akazvimiririra. Kana imwe yadzo ikakundikana kana ichida kugadziriswa, imwe inogona kushandiswa zvakajairika, izvo zviri nyore kushandisa.
