Unonzwisisa here nzira yekudzima chando mufiriji?

Pakushandisa michina yemhepo inotonhorera inotonhorera, makabati ekuisa mufiriji neokuchengetedza mufiriji, nezvimwewo, pachava nechando chinobuda pamusoro pe evaporator. Nekuda kwechando, nzira yekuyerera ichava diki, vhoriyamu yemhepo ichaderera, uye kunyange evaporator ichavharwa zvachose, zvichikanganisa kufamba kwemhepo zvakanyanya. Kana chando chakanyanya kukobvu, zvichaita kuti kutonhora nekutonhorera kwemudziyo wekufiriji kuwedzere kuipa, kuwedzera kushandiswa kwesimba, uye zvimwe zvishandiso zvekufiriji zvinoshandisa.chubhu yekudzikisa chandokunyungudutsa nguva nenguva.

Tubhu remagetsi rinonyungudutsa mvura (electrical defrost heater tube) inzira yekunyungudutsa mvura nekupisa chando chakabatana pamusoro pemuchina uchishandisa machubhu ekudzikisa mvura akarongwa mukati memuchina. Rudzi urwu rwetubhu rekudzikisa mvura imhando yechinhu chemagetsi chinodziya chakaita sechubhu resimbi, chinonziwo defrosting heating tube kana defrost heater tube. Tubhu remagetsi rinonyungudutsa mvura ichinhu chemagetsi chinodziya umo chubhu resimbi rinoshanda segoko, waya yekudzikisa mvura ye alloy sechinhu chinodziya, uye ma terminal (waya) anowanikwa. Nzvimbo inodzikisa magnesium oxide powder inozadzwa zvakanyanya muchubhu resimbi kuti igadzire chinhu chinodziya.

Nekuda kwehunhu hwemidziyo yekuchengetera zvinhu inotonhora, senge hunyoro hwakawanda uye tembiricha yakaderera mumba, kutonhora nekupisa kunowanzoitika,machubhu ekudziyisa anonyungudutsa chandoKazhinji zvinovakirwa pazvinhu zvinodziya zvemagetsi zvakaita sechubhu, zvichishandisa magnesium oxide yakagadziriswa yepamusoro sefiller uye simbi isina ngura segoko. Mushure mekudzikira, mugumo wekubatanidza unovharwa neforoma yakakosha yakadzvanywa nerabha, kuitira kuti chubhu inodziya yemagetsi igone kushandiswa zvakajairika mumidziyo yekuchengetera inotonhora. Inogona kukotama kuita chero chimiro zvichienderana nezvinodiwa nemushandisi uye inoiswa zviri nyore mumitsetse yemuchina wemhepo inotonhora kana pamusoro pe evaporator yekabati inotonhora kana pasi petireyi yekudhonza mvura, nezvimwewo kuti inyungudike. Chimiro chikuru chehita yekunyungudutsandeinotevera:

a) Tsvimbo yemutobvu (mutsetse): yakabatana nemuviri wekupisa, wezvikamu nemagetsi, zvikamu nezvikamu zvakabatana nezvikamu zvinofambisa simbi.

b) Pombi yegoko: kazhinji 304 simbi isingatsvi, inodzivirira ngura zvakanaka.

c) Waya yekupisa yemukati: waya yekudzivirira chromium alloy resistance ye nickel, kana waya yesimbi ye chromium aruminiyamu.

d) Chiteshi chepombi yekupisa yemagetsi chakavharwa nerabha yesilicone.

Pakubatanidza pombi yekupisa, nzira yekubatanidza yepombi yemagetsi inonyungudutsa chandozvinoratidza kuti Y inobatanidza yakaita senyeredzi, Y inofanira kunge yakabatana nemutsetse wepakati, uye izvo zvisina kuratidzwa zvinobatanidza zvitatu. Semuenzaniso, chubhu yekudziya inonyungudutsa yechiller inowanzova 220V, uye mugumo mumwe chete wechubhu yega yega yekudziya inonyungudutsa wakabatana netambo yemoto, uye mumwe mugumo wakabatana netambo isina kusimba. Pamusoro pezvo, simba rekupinda rakaiswa pahugaro hwechubhu yekudziya rinowanzova simba rakatarwa rechubhu yekudziya.

Nzira yekunyungudutsa chando nemagetsi iri nyore kushandisa, asi simba rechubhu yekudziya inonyungudutsakazhinji yakakura, uye kana hunhu hwechubhu yekupisa husina kunaka kana kuti ikashandiswa kwenguva yakareba, zviri nyore kutsva kana kutokonzera moto, saka nzira yemagetsi yekunyungudutsa chando ine njodzi huru dzekuchengetedza uye inoda kuongororwa nguva nenguva. Chubhu yekudzikisa chando inowanzo kukuvara zvinotevera:

1. Kubva pakuonekwa, zvinogona kuonekwa kuti tsvimbo inotungamira yakakuvara, simbi yakafukidza pamusoro yakakuvara, insulator yakakuvara kana kuti chisimbiso chakakundikana.

2, hunhu hwemuviri uye hwemakemikari hwechubhu yekupisa hwachinja uye hahukwanise kuzadzisa zvinodiwa zvekushandisa. Semuenzaniso, chimwe chezviitiko zvinotevera hachichagone kushandiswa:

① Kudzivirira kwemagetsi kwechubhu yekupisa kwakaderera pane kukosha kwakajairika, kukosha kwemagetsi ekubuda kwemvura kwakakura kupfuura 5mA kana kukosha kwekudzivirira kupisa kwakaderera pane 1MΩ

(2) Goko racho rine murazvo unobuda uye zvinhu zvakanyunguduka, uye pamusoro paro pakanga paora zvakanyanya kana kuti hapabvumirwi kugadziriswa.

③ Simba chairo rechubhu yekudziyisa rinodarika simba rakatarwa ne ±10%.

④ Chimiro chechubhu yekupisa chakachinja zvakanyanya, zvichiita kuti ukobvu hwechikamu chekudzivirira husaenzane, uye mashandiro ekudzivirira adzike zvakanyanya nekuyera, izvo zvisingasvike pazvinodiwa.
