Kushanda kwescrew refrigeration compressor

1.Tanga watanga womira

Usati watanga, kubatanidzwa kunofanira kugadziriswa. Paunenge uchitanga kwekutanga, unofanira kutanga watarisa mamiriro ekushanda ezvikamu zvose zve compressor uye zvikamu zvemagetsi.

Zvinhu zvekuongorora ndezvizvi:

a. Vhara shanduko yemagetsi uye sarudza nzvimbo yemanyorero yeanosarudza switch;
b. Dzvanya bhatani realarm, bhero rinorira; dzvanya bhatani rekunyarara, alarm ichabviswa;
c, Dzvanya bhatani rekudziya remagetsi uye mwenje wechiratidzo wakabatidzwa. Mushure mekusimbisa kuti hita yemagetsi iri kushanda, dzvanya bhatani rekumisa kupisa uye mwenje wechiratidzo chekudziya wakadzimwa;
d. Dzvanya bhatani rekutanga pombi yemvura, pombi yemvura inotanga, mwenje wechiratidzo uripo, dzvanya bhatani rekumisa pombi yemvura, pombi yemvura inomira, uye chiratidzo chemwenje chakadzimwa;
e. Dzvanya bhatani rekutanga repombi yemafuta, mwenje wepombi yemafuta uripo, pombi yemafuta iri kumhanya uye ichitenderera nenzira kwayo, uye musiyano wemafuta emafuta unogadziriswa kusvika 0.4 ~ 0.6MPa. Flip the four-way valve kana kudzvanya bhatani rekuwedzera/kudzikira kuti utarise kuti siraidhi vharafu uye mudziyo unoratidza simba zviri kushanda zvakajairika, uye chekupedzisira chesimba chinoratidza chiri pa “0” chinzvimbo.

Tarisa kukosha kweseti yega yega yega yega kuchengetedza kuchengetedza relay kana chirongwa/compressor tembiricha uye kumanikidza kuchengetedza referensi kukosha:

a. Kudzivirirwa kwepamusoro kwekudzivirira: kupera simba≦1.57MPa
b. Yakakwira jekiseni tembiricha yekudzivirira: tembiricha jekiseni remafuta≦65 ℃
c. Kudzivirirwa kwakaderera kwemafuta ekudzvinyirirwa: kusiyana kwemafuta ekumanikidza ≧0.1MPa
d. Kudzivirirwa kwemusiyano wepamusoro pamberi uye mushure mesefa yakanaka: mutsauko wekumanikidza≦0.1MPa
e. Kudzivirirwa kwakaderera kwekudzivirira: kuseta zvinoenderana nemamiriro chaiwo ekushanda

Mushure mekutarisa zvinhu zviri pamusoro, inogona kuvhurwa

Matanho ekubatidza ndeaya anotevera:

a. Iyo yekusarudzira switch inobatidzwa nemaoko;
b. Vhura iyo compressor discharge shut-off valve;
c. Bvisa iyo compressor kune "0" chinzvimbo, inova iyo 10% yekuremedza chinzvimbo;
d. Tanga pombi yemvura inotonhorera uye pombi yemvura yefiriji kuti ipe mvura kune condenser, mafuta inotonhorera uye evaporator;
e. Tanga pombi yemafuta;
f. Masekonzi makumi matatu mushure mekunge pombi yemafuta yatangwa, mutsauko uripo pakati pekumanikidza kweoiri uye dhizaini yekubuda inosvika 0.4 ~ 0.6MPa, dzvanya bhatani rekutanga compressor, compressor inotanga, uye bypass solenoid valve A inovhurawo otomatiki. Mushure mekunge mota ichimhanya zvakajairika, iyo A valve inovharwa otomatiki;
g. Chengetedza kusveta kudzvanywa kwegeji, zvishoma nezvishoma vhura iyo suction stop valve uye nemaoko uwedzere mutoro, uye teerera kune kusveta kudzvanywa kuti kurege kuderera. Mushure mekunge compressor yapinda mukushanda kwakajairika, gadzirisa mafuta ekumanikidza kudzora vharafu kuitira kuti mafuta anomanikidza musiyano uri 0.15 ~ 0.3MPa.
h. Tarisa kana kudzvanywa uye tembiricha yechikamu chimwe nechimwe chemidziyo, kunyanya tembiricha yezvikamu zvinofamba, zvakajairika. Kana paine abnormality, misa muchina kuti uongororwe.
i. Nguva yekutanga yekushanda haifaniri kunge yakareba, uye muchina unogona kuvharwa mukati mehafu yeawa. Kutevedzana kwekuvhara kuri kuburitsa, kumisa mugadziri, kuvhara vharanda rekuvhara-kusveta, kumisa pombi yemafuta, uye kumisa pombi yemvura kuti ipedze yekutanga-up process. Kana bhatani guru rekumisa injini rikadzvanywa, iyo bypass solenoid valve B inovhurwa otomatiki, uye vharuvhu B inovharwa otomatiki mushure mekudzima.

2.Normal kutanga uye kuvhara

The normal startupvarisezvinotevera:

Sarudza bhutsu yemanyorero, maitiro acho akafanana neyekutanga bhutsu.
Sarudza otomatiki magetsi-inobatidza:

  1) Vhura iyo compressor inopedza kuvhara-vharavhavhavha, tanga pombi yemvura inotonhorera uye pombi yemvura yefiriji;

2) Dzvanya bhatani rekutanga compressor, ipapo pombi yemafuta ichaiswa otomatiki mukushanda, uye spool valve inodzokera kune iyo "0" chinzvimbo. Mushure mekusiyana kwemafuta emafuta kwasimbiswa, iyo mota huru inotanga otomatiki mushure mekunonoka kwemasekonzi gumi nemashanu, uye bypass solenoid valve A ichavhurika pakarepo.

3) Kana iyo injini huru inotanga kutanga, kuvhara-kuvhara valve kunofanira kuvhurwa zvishoma nezvishoma panguva imwe chete, kana zvisina kudaro iyo yakanyanyisa yakakwirira yevacuum inowedzera kudengenyeka uye ruzha rwemuchina.

4) Iyo compressor inongoerekana yawedzera mutoro kusvika ku100% uye inopinda yakajairika kushanda mamiriro. Uye otomatiki gadzirisa nzvimbo yekuremedza zvinoenderana nekumanikidza kuseta kukosha kana iyo firiji tembiricha yekuisa kukosha.

Iyo yakajairika yekuvhara maitiro ndeaya anotevera:

Manual shutdown yakafanana neyekuvhara maitiro ekutanga kwekutanga.
Iyo yekusarudza switch iri mune otomatiki chinzvimbo:

1) Shingairira bhatani rekumisa compressor, slide valve ichadzoka pakarepo ku "0" nzvimbo, motokari huru ichamira pakarepo, uye bypass solenoid valve B ichazarura pakarepo panguva imwe chete, pombi yemafuta inongomira mushure mekunonoka, uye B valve ichavhara pakarepo mushure mokumira;

2) Vhara vharuvhu yekuyamwa. Kana iyo yakavharwa kwenguva yakareba, kuvhara kwevhavha yekuvhara inofanirawo kuvharwa;

3) Dzima switch yemagetsi yepombi yemvura uye compressor.

3. Kuchengetedza panguva yekushanda

1) Chenjerera kuona kusveta uye kuburitsa kumanikidza, kusveta uye kupisa tembiricha, tembiricha yemafuta uye kudzvanywa kwemafuta panguva yekushanda kwe compressor, uye kurekodha nguva dzose. Meta inodiwa kuti ive yakarurama.

2) Iyo compressor inomira yega nekuda kweimwe kuchengetedza kuchengetedza panguva yekushanda kwe compressor, uye chikonzero chekusashanda chinofanira kuwanikwa chisati chavhurwa. Hazvibvumirwi kuchinja zvakare nekushandura marongero avo kana zvikanganiso zvekudzivirira.

3) Kana injini huru ichivhara nekuda kwekutadza kwesimba kamwe kamwe, iyo compressor inogona kutendeuka nekuti bypass solenoid valve B haigone kuvhurwa. Panguva ino, suction stop valve inofanira kuvharwa nekukurumidza kuderedza reverse.

4) Kana muchina wacho wakavharwa kwenguva yakareba mumwaka wekushisa wakadzika, mvura yose iri muhurongwa inofanira kudonhedzwa kuti irege kukuvadza kutonhora kumidziyo.

5) Kana iwe ukatanga muchina mumwaka wekushisa wakadzika, tanga wabatidza pombi yemafuta, wodzvanya mota kuti utenderere vhiri rekufambisa kuti ufambise coupling kuita kuti mafuta atenderere mucompressor kuti akwane. Iyi nzira inofanirwa kuitwa mune manual startup mode; kana iri Freon refrigerant, tanga muchina Usati wabatidza hita yemafuta kupisa mafuta ekuzora, tembiricha yemafuta inofanira kunge iri pamusoro pe25 ℃.

6) Kana iyo unit yakavharwa kwenguva yakareba, pombi yemafuta inofanirwa kuvhurwa mazuva ese gumi kana zvakadaro kuti ive nechokwadi chekuti pane mafuta ekuzora munzvimbo dzese dze compressor. Nguva imwe neimwe pombi yemafuta inovhurwa kwemaminitsi gumi; iyo compressor inobatidzwa kamwe chete pamwedzi miviri kusvika ku3, imwe neimwe awa. Iva nechokwadi chokuti zvikamu zvinofamba hazvina kubatana.

7) Usati watanga nguva imwe neimwe, zvakanakisisa kutenderera compressor nguva shomanana kuti uone kana compressor yakavharwa kana kwete, uye kugovera mafuta ekuzora zvakaenzana muzvikamu zvose.
