Nzira yekugadzirisa dambudziko rechiitiko chekuti compressor fluid inorova cylinder mu indasitiri chiller maitiro

1. Zvinokonzera wet stroke failure

① Paunenge uchishandisa manyorero ekutonga, iyo throttle valve inogadziriswa zvisina kufanira, kuvhura kwakakurisa, kana vharanda rinoyangarara harina kuvharwa zvakasimba;

②Ivhavha yekuwedzera inopisa inotadza, kana girobhu rekuona tembiricha rakaiswa zvisizvo, uye kubata hakusi kwechokwadi, zvichikonzera kuvhurika kwakanyanya;

③Iyo evaporator coil yakanyanya kukora uye mutoro wacho mudiki;

④ Kuwanda kwemafuta kuunganidza muhurongwa;

⑤Kutonhodza simba kwecompressor yakakura zvikuru, kana kuti kupisa kweimba yekuchengetera zvinhu zvishoma;

⑥ Kugadziriswa kusina kunaka kwekushanda kwevharuvhu;

⑦ The refrigerant in the firiji system yakazara nefiriji yakawandisa;

⑧Iyo mvura inopa solenoid valve haina kuvharwa zvakasimba;

⑨Mukati-matanho maviri ekumanikidza firiji kutenderera, kana iyo yekusveta vharafu yepasi yekumanikidza nhanho inongoerekana yavharwa kana kuvhurwa (kana nhamba yeanoshanda mayunitsi anongoerekana adzikira uye anowedzera), uye muintercooler. Iyo nyoka coil inoerekana yapinda mumvura, iyo inogona kukonzeresa kunyorova sitiroko yeyakanyanya-kumanikidza nhanho compressor.

Muchidimbu, pane zvinhu zvakawanda zvinokonzera kunyorova kwe compressor, uye zvikonzero zvinofanira kuwanikwa uye kubviswa maererano nemamiriro chaiwo.

2. Zviridzwa, maturusi uye midziyo inoshandiswa kuona kutadza kwekunyorova kwefiriji compressor.

① Chiridzwa: kudzvanywa gauge, multimeter, clamp mita, thermometer, kaviri qi mita.

②Zvishandiso: zvikwiriso, maturusi ekuwedzera pombi, mavharuvhu ekuzadza, mapiresi akanongedza, mapiresi, tochi, maturusi akakosha.

③Zvishandiso: bhodhoro remvura rinoshanda, bhodhoro renitrogen, pombi yevacuum, seti yakazara yegasi welding.

3. Iyo yakawanda nzira yekushanda yekuona kunyorova sitiroko kutadza kwefiriji compressor

Sezvo firiji hurongwa hwemaindasitiri anotonhora ari yakaoma sisitimu inoumbwa nemacondensers, evaporators, mavharuvhu ekuwedzera, uye yakawanda midziyo yemidziyo yakabatana uye inofurirana, kana mudziyo wefiriji ukangotadza, munhu haafanire kungotarisa pane zvimwe Panhanho yenzvimbo. zvinodikanwa kuita ongororo yakazara uye kuongororwa kwakazara kwehurongwa hwese. Muchidimbu, iyo nzira yekuona ndeye:

“Kuteerera kumwe, kubata kaviri, kutarisa katatu, kuongorora ina” seti yenzira dzakakosha.

Kutarisa kumwe: tarisa kusveta kumanikidza uye kuburitsa kumanikidza kwe compressor; tarisa kutonhora kwekamuri yekutonhora; tarisa mamiriro echando evaporator; tarisa mamiriro echando evhavha yekuwedzera inopisa.

Kuteerera kwechipiri: kuteerera inzwi recompressor rinomhanya, panofanira kuva nekufamba kwakajeka kwevhavha. Kana paine ruzha rwekuti “kuburikidza”, ndiko kunzwika kwesando yemvura; teerera kune ruzha rwefiriji inoyerera muvhavha yekuwedzera; teerera inzwi remhepo inotonhora; teerera inzwi revhavha ye solenoid; teerera kuti pane vibration iri pachena here mupombi.

Kubata katatu: kubata tembiricha yekumberi uye kumashure mabhengi e compressor; kubata tembiricha ye compressor cylinder liner uye cylinder musoro; kubata tembiricha yekusveta uye kupera kwepombi. Ongororo ina: Shandisa dzidziso dzakakodzera dzemudziyo wefiriji kuongorora uye kutonga chiitiko, tsvaga chikonzero chekutadza, uye kuibvisa nenzira yakanangwa. Kutonga kwekukundikana kwesando yemvura hakusi kungobva pachando chepombi yekusveta, asi kunyanya kubva pakudonha kunopinza mukupisa kwekupisa. Panguva ino, mhepo yekupedza haizochinji zvakanyanya, asi silinda, crankcase, uye kamuri yekuburitsa zvese zvinokanganiswa. Kutonhora kana chando. Panyaya ye hydraulic shock, inogona kukuvadza lubrication system, kuwedzera basa repombi yemafuta, kudzikisa zvakanyanya cylinder madziro, uye kuboora silinda musoro mune dzakakomba.

4. Iyo nzira yekugadzirisa uye kudzoreredza yakajairika kushanda kwefiriji compressor wet sitiroko kukanganisa

Kubata netsaona yekuvhundutsa kwemvura kunofanirwa kuitwa nekukurumidza, uye muzviitiko zvakakomba, kubata kwemotokari yekukurumidzira kunofanirwa kuitwa. Kana kurohwa kunyoro kunoitika mune imwe-nhanho compressor, chete iyo compressor suction valve inofanirwa kuvharwa, iyo yemvura yekupa valve ye evaporation system inofanira kuvharwa, kana mvura iri mumudziyo inofanira kuderedzwa. noodle. Uye teerera kune kudzvanywa kwemafuta uye tembiricha yekupedza. Kana tembiricha yakwira kusvika pa50 ℃, edza kuvhura vharuvhu yekukweva. Kana tembiricha yekubuda ichiramba ichikwira, unogona kuramba uchiivhura, uye kana tembiricha ichidonha, vhara zvakare.

Nokuda kwe “kunyorova kwemvura” ye-compressor yematanho maviri, nzira yekurapa ye-low-pressure stage wet stroke yakangofanana neye-single-stage compressor. Asi kana paine huwandu hukuru hweammonia huchimhanya muhumburumbira, iyo yakakwirira-pressure compressor inogona kushandiswa kudzvinyirira uye kubuda kuburikidza neintercooler. Usati wapomba pasi, mvura iri muintercooler inofanira kudonhedzwa mubhakiti rekudhonza, uye ipapo kudzvinyirira kunofanira kuderedzwa. Iyo cylinder inotonhorera jekete remvura nemafuta inofanira kunyoroveswa kusati kwadzikiswa kuderedzwa: dhonza mvura inotonhorera muchigadziro kana kuvhura vharafu huru yemvura.

Kana iyo mvura yemvura ye intercooler yakanyanya, iyo yepamusoro-pressure compressor inoratidza “wet stroke”. Nzira yekurapa inofanira kutanga yadzima vheji yekusveta yepasi-pressure compressor, uye wozodzima vharafu yekusveta ye-high-pressure compressor uye vheji yekupa mvura ye intercooler. Kana zvichidikanwa, buritsa ammonia fluid muintercooler mudhiramu rekuburitsa. Kana iyo high-pressure compressor yakanyanyisa chando, mira iyo yakaderera-pressure compressor. Iyo inotevera nzira yekurapa yakafanana neyeimwe-nhanho.
