Nhazi nke mmanụ refrigerant
Otu bụ mmanụ ịnweta omenala;
Nke ọzọ bụ sịntetik polyethylene glycol esters dị ka PO, Polyester mmanụ bụkwa sịntetik polyethylene glycol lubricating oil.POE mmanụ ike ga-eji ọ bụghị nanị na HFC refrigerant usoro, kamakwa na hydrocarbon refrigerant.PAG mmanụ nwere ike iji na HFC, hydrocarbon na ammonia. usoro dị ka refrigerant.
Isi ọrụ nke refrigerating mmanụ
· Belata ọrụ esemokwu, okpomọkụ esemokwu na iyi
· Jupụta mmanụ na mpaghara akara iji hụ na arụ ọrụ akara ma gbochie nkwụsị nke refrigerant
· Ntugharị mmanụ na-ewepụ ihe ndị na-emebi emebi na-emepụta site na esemokwu ígwè, si otú a na-ehichapụ elu esemokwu
· Nye ike hydraulic maka usoro nbudata
Arụmọrụ chọrọ maka refrigerating mmanụ
· Ezigbo viscosity: viscosity nke refrigerating mmanụ mmanụ ọ bụghị nanị na-eme ka esemokwu dị n'elu nke akụkụ ọ bụla na-akpụ akpụ nwere ezigbo mmanu, ma na-ewepụkwa ụfọdụ okpomọkụ site na igwe refrigerating ma na-arụ ọrụ akara. nke nnukwu solubility na mmanụ nke igwe refrigerating, mmanụ nwere viscosity dị elu kwesịrị ịtụle iji merie mmetụta nke mmanụ na-agbaze site na refrigerant.
Obere ihe na-agbanwe agbanwe, ebe ọkụ dị elu: ọnụọgụ mgbanwe mmanụ na-ekpo ọkụ ka ukwuu, yana okirikiri refrigerant, ego mmanụ bụ, ka ọnụọgụ mmanụ refrigeration dị warara nke ebe ọkụ kwesịrị ịdị elu karịa igwe iyuzucha okpomọkụ n'elu 25 ~ 30 ℃
· Ezi chemical kwụsie ike na thermal oxidation kwụsie ike: na ikpeazụ mkpakọ refrigerating igwe na-arụ ọrụ okpomọkụ bụ 130 ℃ ~ 160 ℃, okpomọkụ nke oyi kpọnwụrụ mmanụ heats na decomposition nke mgbe niile metamorphism, mepụta carbon nkwụnye ego na refrigerating igwe malfunction na wear.Ọzọkwa, na decomposition. ngwaahịa mmanụ ga-emeghachi omume na refrigerant, nke ga-eme ka mmetụta jụrụ oyi ka njọ, na acid nke ga-esi na ya pụta ga-emebisi akụkụ nke refrjiraeto.
· Enweghị mmiri na adịghị ọcha: n'ihi na mmiri na-ekpo ọkụ na evaporator ga-emetụta arụmọrụ ọkụ ọkụ, kọntaktị na refrigerant ga-eme ka ọkpụkpụ nke refrigerant dịkwuo ngwa ngwa ma mebie akụrụngwa, ya mere mmanụ refrigerant enweghị ike ịnwe mmiri na adịghị ọcha.
Ndị ọzọ: Mmanụ refrigerating kwesịrị inwe ezigbo ihe na-egbochi ụfụfụ ma ghara igbari ma ọ bụ gbasaa na rọba, waya enamel na ihe ndị ọzọ.
Ihe ndị ị ga-atụle n'ịhọrọ mmanụ refrigerating
· Viscosity: elu ọsọ nke compressor, elu viscosity nke refrigerating mmanụ kwesịrị ịdị.
· Nkwụsi ike nke okpomọkụ: A na-atụkarị nkwụsi ike nke thermal site na ebe ọkụ ọkụ nke mmanụ igwe oyi kpọnwụrụ .Flash point na-ezo aka na okpomọkụ nke uzuoku nke igwe refrigerating mmanụ na-egbuke egbuke mgbe ọ dị ọkụ.Refrigerator mmanụ flash point ga-adị elu karịa nke ahụ. nke Compressor iyuzucha okpomọkụ, dị ka R717, R22 compressor na-eji refrjiraeto mmanụ flash ebe kwesịrị n'elu 160 ℃.
· Fluidity: igwe refrigerating mmanụ kwesịrị inwe ezigbo mmiri na obere okpomọkụ.Na evaporator, n'ihi obere okpomọkụ na ụba viscosity mmanụ, mmiri mmiri ga-adị njọ.Mgbe igwe refrigerating mmanụ ruru ụfọdụ okpomọkụ, ọ ga-akwụsị na-asọpụta. Ebe na-ekpo ọkụ nke refrigerating mmanụ igwe chọrọ ka ọ dị ala, karịsịa ebe oyi nke mmanụ nke igwe cryogenic dị ezigbo mkpa.
· Solubility: solubility dị iche iche refrigerants na refrigerant mmanụ dị iche iche, nke nwere ike roughly kewara n'ime atọ: otu bụ ihe a na-apụghị sosoluble, nke ọzọ adịghị ike, na nke ọzọ dị n'etiti abụọ n'elu.
· Turbidity point: okpomọkụ nke mmanụ refrigerant na-amalite ịgbapụta paraffin (mmanụ na-aghọ turbid) ka a na-akpọ turbidity point.Mgbe refrigerant dị, ebe turbidity nke mmanụ refrigerant ga-ebelata.
Isi ihe na-akpata mmebi nke mmanụ refrigerating
· Ịgwakọta mmiri: n'ihi ntinye nke ikuku n'ime usoro refrigeration, mmiri dị n'ikuku na-ejikọta ya na mmanụ igwe refrigerating mgbe kọntaktị. mmanụ refrigerating, viscosity na-ebelata ma metal na-emebi emebi. Na sistemu refrigeration freon, a na-akpatakwa "plọg ice".
· Oxidation: mgbe a na-eji mmanụ refrigerate eme ihe, mgbe ikpo ọkụ nke compressor dị elu, ọ nwere ike ịkpata mmebi oxidative, karịsịa mmanụ refrigerating na nkwụsi ike nke kemịkal na-adịghị mma, nke na-adịkarị mfe ịdaba.N'ime oge, a ga-emepụta ihe ndị fọdụrụ na mmanụ refrigerating, na-eme ka mmanye nke bearings na ebe ndị ọzọ na-emebi emebi. Ịgwakọta ihe ndị na-emepụta ihe na ihe ndị na-emepụta ihe n'ime igwe na-eme ka mmanụ na-ekpo ọkụ ga-eme ka ọ dịkwuo nká ma ọ bụ oxidation.
· Ịgwakọta mmanụ refrigerating mmanụ: mgbe ọtụtụ ụdị dị iche iche nke igwe refrigerating mmanụ ga-ebelata viscosity nke refrigerating mmanụ igwe ga-ebelata, na ọbụna e guzobere mmanụ ihe nkiri ga-emebi.
Ọ bụrụ na ụdị igwe igwe refrigerating abụọ nwere ihe mgbakwunye mgbochi oxidation dị iche iche nke ihe dị iche iche, mgbe agwakọtara ọnụ, mgbanwe kemịkalụ nwere ike ime na ọ ga-ebuli elu, nke ga-emetụta mmanye nke compressor.Ya mere, a ga-aṅa ntị mgbe ị na-eji.
· Enwere adịghị ọcha na mmanụ refrigerating
Otu esi ahọrọ mmanụ refrigerate
· Họrọ mmanụ mmanye dị ka ụdị mkpakọ: compressor nke igwe refrigerating nwere ụdị piston atọ, skru na centrifugal.Ụdị abụọ mbụ nke mmanụ mmanye na-akpakọrịta kpọmkwem na refrigerant abịakọrọ, na-atụle mmekọrịta dị n'etiti mmanụ mmanu na refrigerant. A na-eji mmanụ Centrifugal naanị iji kpoo rotor bearing.Enwere ike ịhọrọ ya dabere na ibu na ọsọ.
· Họrọ mmanụ lubricating dị ka ụdị refrigerant: mmanụ mmanụ na-ekpo ọkụ na kọntaktị kpọmkwem na refrigerant kwesịrị ịtụle mmekọrịta dị n'etiti abụọ ahụ. Dịka ọmụmaatụ, refrigerant dị ka freon nwere ike igbari na mmanụ ịnweta mmanụ, ya mere ọkwa viscosity nke lubricating a họọrọ. mmanụ kwesịrị ịbụ otu ọkwa dị elu karịa nke refrigerant insoluble, nke mere na iji gbochie mmanụ lubricating na-enweghị ike ijide n'aka mgbe a gbazere ya. Tụkwasị na nke ahụ, ekwesịrị iburu n'uche na obere mmanụ mmanụ a na-ejikọta na refrigerant ga-emetụta. ọrụ nke refrigeration usoro. Ebe flocculation nke refrigerating igwe mmanụ bụ àgwà index iji chọpụta ma lubricating mmanụ agwakọta na refrigerant nwere ike ịkpali wax kristal na-egbochi refrigeration usoro.
Họrọ mmanụ lubricating dị ka evaporation okpomọkụ nke refrigerant: n'ozuzu na-ekwu okwu, refrigerant evaporator na obere evaporation okpomọkụ kwesịrị ịhọrọ refrigerant mmanụ na ala kefriza ebe, ka ịzena lubricating mmanụ na-ebu refrigerant na refrigeration usoro si condensing na throttle. valvụ na evaporator, na-emetụta arụmọrụ refrigeration.
Ebe ntụ oyi nke mmanụ mmanụ a na-eji na ngwa nju oyi amonia kwesịrị ịdị ala karịa okpomọkụ ikuku.
Ebe a na-eji freon dị ka ihe na-eju oyi, ebe na-ekpo ọkụ nke mmanụ na-ete mmanụ nwere ike ịdị elu karịa okpomọkụ nke evaporation.
Họrọ mmanụ mmanye dị ka ọnọdụ ọrụ nke friza si dị.
HERO-TECH na-eji naanị ọkwa dị elummanụ nju oyi.Akụkụ niile nke chillers anyị dị oke mma, otu ihe ahụ na-aga maka mmanụ refrigerated.Anyị chọrọ ezigbo mmanụ refrigeration iji kwado igwe kwụsiri ike na ogologo oge nke igwe.
