(4) Iyo yemvura level mita yeyakamira oiri separator yakadzora mufiriji mvura;Panguva ino hurefu hwemvura hunogona kunge husiri hwechokwadi, hunofanirwa kufungidzira hurefu chaihwo hwehurefu hwemafuta.

 

35.Chikonzero uye kurapwa kwecompressor inversion kana screw compressor yamira?

A: (1) Mavharuvhu ekusveta nekupedza simba haana kuvharwa zvakasimba;Gadzirisa uye bvisa ndiro yevhavha yakanamatira.

(2)Kudzivirira reverse bypass pombi vharafu haina kuvhurwa nenguva;Tarisa uye kugadzirisa.

 

36.Sei tembiricha yekusveta yakaderera uye maitiro ekuita nayo?

A: (1)Too yakawanda refrigerant mu evaporator, gasi-mvura yekuparadzanisa kana yakaderera kutenderera kutenderera barrel;Gadzirisa iyo valve yekugovera yemvura, mira kana kuderedza huwandu hwekupa kwemvura, uye kunyange kuburitsa yakawandisa refrigerant kune yemvura yekuburitsa bucket.

(3)Tiye evaporator kupisa kupisa kunyatsoshanda kunoderedzwa;Chenesa evaporator kana kubvisa mafuta.

 

37.Ko kukosha kwekuchengetedza kuchengetedza kwemidziyo yefiriji uye bvunzo yevacuum yehurongwa inotsanangurwa sei?

A: Refrigeration mudziyo kuchengetedza kukosha zvinoenderana nechigadzirwa chekuraira bhuku.Iwo kuchengetedza kuchengetedza kukosha kwe LG akateedzana screw firiji compressor ndeaya anotevera (yekutarisa):

(1) Jekiseni tembiricha kudzivirira yakakwirira: 65℃(vhara);

(2) Kudzivirirwa kwakaderera kwekudzivirira: -0.03Mpa (shutdown), kukosha uku kunogona kuchinjwa;

(3) Kudzivirirwa kwepamusoro-soro kwekudzivirira: 1.57Mpa (kuvhara);

(4)Oil sefa kudzvinyirirwa musiyano mukuru kudzivirira: 0.1Mpa (kuvhara);

(5)Overload kuchengetedzwa kwemota huru (yekudzivirira kukosha zvinoenderana nezvinodiwa zvemota);

(6) Kudzivirirwa kwakaderera pakati pemafuta ekumanikidza uye kupera simba: 0.1Mpa (kuvhara);

(7)Overload kuchengetedzwa kwepombi yemafuta (yekudzivirira kukosha zvinoenderana nezvinodiwa zvemota);

(8) Kudzivirirwa kwakadzikira kwekushisa kwemvura kutonhora, brine unit uye ethylene glycol unit, uye kudzivirira kwemvura-kuvharwa kwe evaporator uye condenser.

(9)Condenser, reservoir yemvura, separator yemafuta, mafuta muunganidzi kuchengetedza vharafu kuvhura kumanikidza: 1.85Mpa;Yakazara mvura evaporator, gasi-mvura yekuparadzanisa, yakaderera kutenderera kutenderera kwemvura yekuchengetera mbiya, intercooler, ehupfumi vharafu kuvhura kumanikidza: 1.25Mpa.

 

Vacuum test ye system:

Chinangwa chevacuum test yegadziriro ndeyekutarisa kusimba kwegadziriro pasi pevacuum uye kugadzirira kuzadza kwefiriji uye refrigerant mafuta.Pombisa sisitimu kusvika 5.33kpa (40mm Hg) uye bata kwemaawa makumi maviri nemana.Kuwedzera kwekumanikidza hakufanirwe kudarika 0.67kpa (5mm Hg).

 

38.Kuronga sei kugadzirisa kukuru, kwepakati uye kuduku midziyo?

A: (1) Kutenderera kwekugadziriswa kukuru, kwepakati uye kudiki kwemidziyo kucharongwa nemushandisi zvinoenderana nezviri mugwaro rekushandisa rekushandisa uye nekutarisa nharaunda yekushanda yemushandisi, mamiriro ekushanda, nguva yekutyaira yegore, kurova kwekugadzira nezvimwe. maitiro.Kugadzirisa panguva.Zviri mukati mekugadzirisa kukuru, kwepakati uye kudiki kwemidziyo ichatemwa zvinoenderana nemirairo yemidziyo uye mashandisirwo chaiwo emidziyo.

 

39.Ungaronga sei iyo huru, yepakati uye diki kugadzirisa yepiston refrigeration compressor?(zvekureva)

(1) Inguvai yekugadziridza?

A: (1) Ongorora maawa 8 000 oga oga kana kupfuura.

(2) Chii chiri mukati mekugadzirisa?

A: (2) Tarisa uye uchenese zvikamu, uye kuyera dhigirii yekupfeka yezvikamu: zvakadai se cylinder, piston, piston ring, crankshaft, kutakura, tsvimbo yekubatanidza, kusveta uye kupera kwevhavha, pombi yemafuta, etc. Kupfeka zvishoma kunogona kuva yakagadziriswa kushandiswa, kupfeka kunorema kunofanira kutsiviwa.Kuongororwa kwemavharuvhu ekuchengetedza uye zviridzwa (zvinofanira kuitwa nemadhipatimendi anokwanisa).Chenesa sefa yefiriji oiri system, refrigerant system uye mvura system.

(3) Ndeipi nguva yekugadzirisa kwepakati?

A: (3) Kugadziriswa kwepakati pese maawa 3000-4000 kana zvakadaro.

(4) Kosi yepakati ndeipi?

A: (4) Kunze kwekugadziriswa kudiki, tarisa uye gadzirisa iyo clearance pakati pecylinder nepiston, iyo clearance pakati pepiston ring lock, kubvumidzwa pakati pekubatanidza tsvimbo yehukuru musoro nepini yepini, kubvumidzwa pakati pebhengi uye main axle dhayamita, iyo clearance. pakati pemhepo vharafu uye piston, etc. Tarisa piston pini, silinda, crankshaft uye zvimwe zvikamu kupfeka dhigirii.Tarisa iyo lubrication system.Tarisa uone kana mabhaudhi ekubatanidza uye anchor akasununguka.

(5) Ndeipi nguva yekugadziriswa kudiki?

Mhinduro: (5) Mushure mekugadzirisa kwepakati, kugadzirisa kudiki kunoitwa maawa ega ega 1000-1200 kana zvakadaro.

(6) Chii chiri mukati mekugadzirisa kudiki?

A: (6) Chenesa pombi yemvura inotonhorera;Tarisa piston, mhete yegesi, mhete yemafuta uye kusveta uye kupera kwevhavha, shandura iyo yakakuvadzwa yevhavha disc uye valve spring, nezvimwewo.Shandura mafuta efriji;Tarisa coaxiality yemota uye crankshaft.

 

40.Maitiro ekugadzirisa yakakura, yepakati uye diki kugadzirisa ye screw refrigeration compressor?(zvekureva)

Iyo nguva yekuchengetedza ye screw compressor unit ine chekuita nezvakawanda zvinhu.Mashoko anotevera ndeekureva.

A: (1) Iyo mota ye screw compressor: disassembly, kugadzirisa uye kutsiva, inotakura refueling, nguva yemakore maviri, ona mota yekuraira bhuku.

(2) kubatanidza: tarisa coaxiality ye compressor uye mota (tarisa kana iyo elastic transmission piece yakuvadzwa kana pini yerabha yakapfekwa).Nguva yacho ndeye 3-6 mwedzi.

(3) Oiri separator: kuchenesa mukati, izwi iri 2 makore.

(4) Oiri inotonhorera: bvisa chiyero (kutonhora kwemvura), chiyero chemafuta, nguva yehafu yegore;Zvichienderana nemhando yemvura uye mamiriro etsvina.

(5) Pombi yemafuta: bvunzo yekuvuza uye kugadzirisa, nguva ye1 gore.

(6) Oiri sefa (kusanganisira crude mafuta sefa), suction filter: kuchenesa, nguva yehafu yegore.Yekutanga kutyaira maawa 100-150 inofanira kucheneswa.

(7) mafuta anodzvinyirira anogadzirisa vharafu: kudzora kugona kwekutarisa, nguva ye1 gore.

(8) Spool valve: chiitiko chekuongorora, nguva yemwedzi 3-6.

(9) Vavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharwa,kutemerwa geji, thermometer: cheki, nguva 1 gore.

(10) Chengetedza valve, kusveta uye kupera kwevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhaswe, pressure gauge valve: kuchengetedza, nguva ye2 years.

(11) Pressure relay, tembiricha relay: tarisa, izwi iri rinenge hafu yegore.Tarisa kune mirairo.

(12) Midziyo yemagetsi: kuongororwa kwechiito, nguva yemwedzi mitatu.Tarisa kune mirairo.
