Zvikonzero zvekutadza kwakanyanya kweiyo screw chiller ndeiyi inotevera

Iyo yekuburitsa pressure ye screw chiller compressor yakakwira zvakanyanya, zvichiita kuti iyo yepamusoro-pressure protection relay ishande. The compressor discharge pressure inotaridza kudzvanywa kwekumanikidza, kukosha kwakajairika kunofanirwa kunge kuri 1.4 ~ 1.6MPa, uye kukosha kwekudzivirira kunoiswa ku2.0MPa. Kana kudzvinyirirwa kwakanyanyisa kwenguva yakareba, kuchaita kuti compressor inoshanda ikozvino kuti ive yakakura zvikuru, motokari iri nyore kupisa, uye zviri nyore kukonzera kukanganisa kune compressor exhaust valve. Zvikonzero zvekutadza kukuru kwemagetsi ndezvizvi:

(1) Tembiricha yemvura inotonhorera yakakwira zvakanyanya uye iyo condensation mhedzisiro haina kunaka. Mamiriro ekushanda akayerwa emvura inotonhorera inodiwa nescrew chiller ndeye 30 ~ 35 ℃. Tembiricha yemvura yakakwira uye kusapisa kwakashata kunozotungamira mukumanikidza kwakanyanya. Ichi chiitiko chinowanzoitika mumwaka wekushisa kwakanyanya. Chikonzero chekupisa kwemvura kwakakwirira kunogona kuva: kutonhora kweshongwe kukundikana, sekuti fan haina kutendeuka kana kunyange kuchinjwa, muparidzi wemvura haatendeuki, inoratidzwa sezvo kutonhora kwemvura kunotonhora kwakanyanya, uye inokwira nokukurumidza; kunze kwekushisa kwekunze kwakakwirira, nzira yemvura ipfupi, uye muwandu wemvura inogona kuparadzirwa Muchiitiko ichi, kutonhora kwemvura inotonhorera kunowanzochengetedzwa pamwero wakakwirira, iyo inogona kugadziriswa nekuwedzera tangi yekuchengetedza.

(2) Mvura inotonhorera inoyerera haina kukwana uye haigoni kusvika kune yakatemerwa mvura inoyerera. Basa guru nderokuti mutsauko wepakati pakati peinopinza uye yekubuda mvura yeyuniti inova diki (ichienzaniswa nekutsikirira musiyano pakutanga kwegadziriro inoiswa mukushanda), uye mutsauko wekushisa unova mukuru. Chikonzero chekusakwana kwemvura kuyerera ndiko kushaikwa kwemvura muhurongwa kana kuvapo kwemhepo. Mhinduro ndeyekuisa vheji yekuburitsa pakukwirira kwepombi kuti ipere; iyo pombi sefa yakavharwa kana kusarudzwa kwakanyanyisa, uye kupenya kwemvura kunogumira. Iwe unofanirwa kusarudza sefa yakakodzera uye Chenesa sefa nguva dzose; pombi yemvura idiki uye haienderane nehurongwa.

(3) Iyo condenser yakasvibiswa kana kuvharwa. Condensate mvura inowanzova mvura yemupombi. Zviri nyore kuyera kana tembiricha iri pamusoro pe30 ℃. Nekuti shongwe yekutonhodza yakavhurika, inoiswa pachena kumhepo. Guruva uye zvinhu zvekunze zvinogona kupinda nyore nyore mumvura inotonhorera, zvichiita kuti condenser ive yakasviba uye ichivharira uye nzvimbo yekutsinhanisa kupisa idiki. , Kubudirira kwakaderera, uye kunobatawo kuyerera kwemvura. Kuita ndekwekuti mutsauko wekumanikidza uye mutsauko wekushisa pakati peinopinza uye yekubuda mvura yeyuniti inova yakakura, tembiricha yekumusoro uye yakaderera yecondenser yakakwira zvakanyanya kana condenser yabatwa neruoko, uye iyo condenser yekubuda yemhangura pombi inopisa. Iyo screw chiller inofanirwa kugezeswa kumashure nguva nenguva, uye kuchenesa kemikari nekudzikisa kunofanirwa kuitwa kana zvichidikanwa.

(4) Mufiriji wakachajwa. Mamiriro ezvinhu aya anowanzo kuitika mushure mekugadzirisa, uye inoratidzwa seyakanyanya kuyamwa uye kupera simba uye kuenzanisa kumanikidzwa, uye yakakwirira compressor inoshanda ikozvino. Inofanira kufefeterwa maererano nekusveta uye kuburitsa kudzvanywa, kuenzanisa kudzvanywa uye kushanda ikozvino pasi peyakayerwa mamiriro kusvika zvakajairika.

(5) Magasi asingabatike akadai semhepo nenitrogen anosanganiswa mufiriji. Izvi zvinowanzoitika mushure mekugadzirisa, uye vacuum haina kukwana. Inogona chete kudonhedzwa, kubudiswazve, uye kuzadzwa nefiriji.

(6) Nhema dzenhema dzinokonzerwa nemagetsi emagetsi. Nekuti iyo yakakwira-voltage yekudzivirira relay yakanyorova, isina kubatwa zvakanaka kana kukuvadzwa, iyo unit electronic board inonyorova kana kukuvadzwa, uye kutadza kutaurirana kunokonzera alarm yenhema. Kune rudzi urwu rwekukanganisa kwenhema, iyo HP yekukanganisa chiratidzo pabhodhi remagetsi kazhinji inodzima kana kupenya zvishoma, iyo yakakwira-voltage yekudzivirira relay haina kurongeka nemaoko reset, komputa inoratidza “HP RESET”, kana inonyangarika otomatiki, iyo inomhanya ye Compressor yakajairika, uye kusveta uye kuburitsa kudzvanywa kwakajairika.
