Ukutshintsha koxinzelelo kwiNkqubo yeFriji

Emva kokuzaliswa, ifriji igeleza kwiqokobhe le-aluminium (oko kukuthi, ngaphakathi kokutshintsha) ngomngxuma omncinci phantsi kwegobolondo le-aluminium. Umgodi wangaphakathi usebenzisa i-rectangular ring kunye ne-diaphragm ukwahlula ifriji ukusuka kwindawo yombane kwaye uyitywine ngexesha elifanayo.

Xa uxinzelelo lufikelela kwixabiso le-low-pressure switch-on value 0.225 + 0.025-0.03MPa, i-diaphragm ye-low-pressure diaphragm (iqhekeza eli-1) liguqulwa, isihlalo se-diaphragm sinyuka sinyuka, kwaye isihlalo se-diaphragm sityhala ingcongolo ephezulu ukuba inyuke, kunye nezinto ezidibanayo kwingcongolo ephezulu zikwipleyiti emthubi esezantsi. Uqhagamshelwano lwe-compressor ludibene, oko kukuthi, uxinzelelo oluphantsi luxhunyiwe, kwaye i-compressor iqala ukusebenza.

Uxinzelelo luyaqhubeka nokunyuka. Xa ifikelela kwixabiso eliphezulu lokuqhawula uxinzelelo lwe-3.14 ± 0.2 MPa, i-diaphragm yoxinzelelo oluphezulu (iziqwenga ezi-3) iyajikeleza, ityhala intonga ye-ejector phezulu, kwaye intonga ye-ejector iphumle kwingcongolo engezantsi, ukuze ingcongolo ephantsi inyukele phezulu; kunye noqhagamshelwano kwi-plate ephantsi ephuzi Iphuzu lihlulwe kumnxeba kwingcongolo ephezulu, oko kukuthi, uxinzelelo oluphezulu lunqanyuliwe, kwaye i-compressor iyayeka ukusebenza.

Uxinzelelo ngokuthe ngcembe luyalingana (okt luyancipha). Xa uxinzelelo lwehla kwixabiso eliphezulu lokutshintshela kwi-high-pressure minus 0.6±0.2 MPa, i-diaphragm yoxinzelelo oluphezulu iphinda ibuyele, intonga ye-ejector ihla, kwaye ingcongolo ephantsi ibuyisela. Abafowunelwa kwipleyiti etyheli esezantsi kunye nabafowunelwa kwingcongolo ephezulu bayabuyiselwa. Uqhagamshelwano lwamanqaku, oko kukuthi, uxinzelelo oluphezulu luxhunyiwe, i-compressor isebenza.

Xa uxinzelelo lwehla kwixabiso eliphantsi lokunqunyulwa koxinzelelo lwe-0.196± 0.02 MPa, i-diaphragm ephantsi yoxinzelelo iphinda ibuyele, isihlalo se-diaphragm sihla, ingcongolo ephezulu ihlalisa phantsi, kwaye umnxibelelwano kwiqabunga eliphezulu elityheli liyahlukana nomfowunelwa. kwingcongolo esezantsi, oko kukuthi, ukuqhawula uxinzelelo oluphantsi , Icompressor iyayeka ukusebenza.

Ekusetyenzisweni kwangempela, ukutshintshela kunqanyuliwe xa kungekho xinzelelo. Ifakwe kwisixokelelwano somoya wemoto. Emva kokuba ifriji igcwaliswe (ngokuqhelekileyo i-0.6-0.8MPa), utshintsho loxinzelelo lukwimeko. Ukuba ifriji ayivuzi, Inkqubo isebenza ngokuqhelekileyo (1.2-1.8 MPa);Tusoloko elayita.

wisikhukhukazi iqondo lobushushu ngaphezu degrees ezisixhenxe okanye ezisibhozo, Xa inkqubo ayisebenzi ngokuqhelekileyo, ezifana yokuchitha ubushushu amahlwempu condenser okanye ezimdaka / ukuvaleka umkhenkce inkqubo, kunye noxinzelelo inkqubo idlula 3.14±0.2 MPa, iswitshi iya kuguqulwa. icimile; Ukuba ifriji iyavuza okanye iqondo lobushushu lingaphantsi kwesixhenxe okanye iidigri ezisibhozo, kwaye uxinzelelo lwenkqubo lungaphantsi kwe-0.196±0.02 MPa, iswitshi iya kuvalwa. Ngamafutshane, umtshintshi ukhusela i-compressor.
