1.Yambani choyamba ndi kusiya
Asanayambe, kugwirizana kuyenera kusinthidwa. Mukayamba kwa nthawi yoyamba, muyenera kuyang'ana kaye momwe zimagwirira ntchito mbali zonse za kompresa ndi zida zamagetsi.
Zinthu zoyendera ndi izi:
a. Tsekani chosinthira mphamvu ndikusankha malo amanja a chosinthira chosankha;
b. Dinani batani la alamu, belu la alamu lidzalira; dinani batani la chete, alamu idzachotsedwa;
c, Kanikizani batani lotenthetsera magetsi ndipo nyali yowunikira yayatsidwa. Pambuyo potsimikizira kuti chowotcha chamagetsi chikugwira ntchito, dinani batani loyimitsa kutentha ndipo chizindikiro cha kutentha chimazimitsidwa;
d. Kanikizani batani loyambira pampu yamadzi, mpope wamadzi umayamba, kuwala kowonetsa kumayatsidwa, dinani batani loyimitsa pampu yamadzi, pampu yamadzi imayima, ndipo chowunikira chazimitsa;
e. Dinani batani loyambira la mpope wamafuta, chowunikira cha mpope wamafuta chayatsidwa, pampu yamafuta ikuyenda ndikuzungulira kolondola, ndipo kusiyana kwamafuta kumasinthidwa kukhala 0.4 ~ 0.6MPa. Yendetsani valavu yanjira zinayi kapena dinani batani lowonjezera / kuchepetsa kuti muwone ngati valavu yojambulidwa ndi chipangizo chowonetsera mphamvu zikugwira ntchito bwino, ndipo chizindikiro chomaliza cha mphamvu chili pa "0" malo.
Yang'anani mtengo wamtundu uliwonse wachitetezo chodzitchinjiriza kapena pulogalamu/Kutentha kwa compressor ndi mtengo wachitetezo chachitetezo:
a. Chitetezo champhamvu yotulutsa mpweya: kuthamanga kwa mpweya≦1.57MPa
b. Kuteteza kutentha kwa jakisoni wamafuta: kutentha kwa jakisoni wamafuta≦65 ℃
c. Kutetezedwa kwa kusiyana kwamafuta ochepa: Kusiyana kwamafuta amafuta ≧0.1MPa
d. Kutetezedwa kwa kusiyana kwamphamvu kwambiri musanayambe komanso pambuyo pa fyuluta yabwino: kusiyana kwa kuthamanga≦0.1MPa
e. Chitetezo chochepa champhamvu choyamwa: kukhazikitsidwa molingana ndi zochitika zenizeni zogwirira ntchito
Pambuyo poyang'ana zomwe zili pamwambazi, zikhoza kuyatsidwa
Njira zoyatsa ndi izi:
a. Chosinthira chosankha chimayatsidwa pamanja;
b. Tsegulani valavu yotulutsa kompresa;
c. Tsitsani kompresa pamalo a "0", omwe ndi malo olemetsa 10%;
d. Yambitsani mpope wa madzi ozizira ndi mpope wamadzi wa refrigerant kuti mupereke madzi ku condenser, mafuta ozizira ndi evaporator;
e. Yambani pompa mafuta;
f. Masekondi a 30 mutatha kupopera mafuta, kusiyana pakati pa kuthamanga kwa mafuta ndi kuthamanga kwa mafuta kumafika pa 0.4 ~ 0.6MPa, dinani batani loyambira la compressor, compressor ikuyamba, ndi bypass solenoid valve A imatsegulanso. Galimoto ikatha kuyenda bwino, valve A imatsekedwa;
g. Yang'anani kayezedwe kachiwopsezo, pang'onopang'ono tsegulani valavu yoyimitsa ndikuwonjezera katunduyo pamanja, ndipo samalani kuti mphamvu yakukokera isakhale yotsika kwambiri. Compressor ikalowa ntchito yabwinobwino, sinthani valavu yoyendetsera mafuta kuti kusiyana kwamafuta ndi 0.15 ~ 0.3MPa.
h. Yang'anani ngati kupanikizika ndi kutentha kwa gawo lililonse la zipangizo, makamaka kutentha kwa magawo osuntha, ndi abwino. Ngati pali vuto lililonse, imitsani makinawo kuti awonedwe.
ndi. Nthawi yoyamba yogwira ntchito siyenera kukhala yayitali, ndipo makinawo amatha kutsekedwa pafupifupi theka la ola. Njira yotsekera ndikutsitsa, kuyimitsa wolandirayo, kutseka valavu yotsekera, kuyimitsa pampu yamafuta, ndikuyimitsa pampu yamadzi kuti amalize ntchito yoyamba yoyambira. Batani lalikulu loyimitsa injini likakanikizidwa, valavu ya solenoid B imatsegulidwa yokha, ndipo valavu B imatsekedwa yokha ikatsekedwa.
2.Normal chiyambi ndi shutdown
Kuyamba kwabwinobwinondimotere:
Sankhani buku lamanja, ndondomekoyi ndi yofanana ndi boot yoyamba.
Sankhani kuyatsa basi:
1) Tsegulani valavu yotsekera yotulutsa kompresa, yambitsani mpope wamadzi ozizira ndi mpope wamadzi wa refrigerant;
2) Dinani batani loyamba la compressor, ndiye mpope wa mafuta udzangoyamba kugwira ntchito, ndipo valavu ya spool idzabwereranso ku "0".
3) injini yayikulu ikayamba, valavu yotsekera iyenera kutsegulidwa pang'onopang'ono nthawi yomweyo, apo ayi, vacuum yayikulu kwambiri imawonjezera kugwedezeka ndi phokoso la makinawo.
4) Compressor imangowonjezera katunduyo mpaka 100% ndikulowa m'malo ogwirira ntchito. Ndipo sinthani malo olemetsa molingana ndi mtengo wokhazikitsira kukakamiza kapena mtengo wokhazikitsira kutentha kwa refrigerant.
Njira yanthawi zonse yotsekera ndi motere:
Kutseka kwapamanja ndikofanana ndi kutseka koyambira koyamba.
Chosinthira chosankha chili pamalo amodzi:
1) Kanikizani batani loyimitsa compressor, valavu ya slide idzabwereranso ku "0" malo, injini yaikulu idzangoyima, ndipo bypass solenoid valve B idzatsegulidwa nthawi yomweyo, pampu yamafuta idzangoyima ikachedwa, ndipo B valve idzatseka ikangoyima;
2) Tsekani valavu yoyimitsa kuyamwa. Ngati yatsekedwa kwa nthawi yayitali, valavu yotulutsa mpweya iyeneranso kutsekedwa;
3) Zimitsani mphamvu yosinthira pampu yamadzi ndi kompresa.
3. Kusamala panthawi ya ntchito
1) Samalani kuti muwone kuthamanga ndi kutulutsa, kutentha ndi kutulutsa, kutentha kwamafuta ndi kuthamanga kwamafuta panthawi ya compressor, ndikulemba pafupipafupi. mita imafunika kuti ikhale yolondola.
2) Compressor imangoyimitsa yokha chifukwa chachitetezo chachitetezo pakanthawi kamene kakugwira ntchito, ndipo chomwe chimayambitsa vutoli chiyenera kuzindikirika chisanatsegulidwe. Sichiloledwa kuti chiyatsenso posintha makonda awo kapena kutchingira zolakwika.
3) Pamene injini yaikulu ikutseka chifukwa cha kulephera kwadzidzidzi kwa mphamvu, kompresa ikhoza kusintha chifukwa chodutsa solenoid valve B sichikhoza kutsegulidwa. Panthawiyi, valavu yoyimitsa kuyamwitsa iyenera kutsekedwa mwamsanga kuti ichepetse kumbuyo.
4) Ngati makinawo atsekedwa kwa nthawi yayitali m'nyengo yotentha, madzi onse mu dongosolo ayenera kutsekedwa kuti asawonongeke ndi kuzizira kwa zipangizo.
5) Mukayambitsa makinawo munyengo yotentha kwambiri, yatsani kaye mpope wamafuta, ndikusindikiza mota kuti izungulire chiwongolero kuti musunthe cholumikizira kuti mafuta azizungulira mu kompresa kuti azipaka mafuta okwanira. Izi ziyenera kuchitidwa poyambira pamanja; ngati ndi refrigerant ya Freon, yambani makinawo Musanayatse chowotcha kuti mutenthe mafuta opaka mafuta, kutentha kwamafuta kuyenera kukhala pamwamba pa 25 ℃.
6) Ngati unityo yatsekedwa kwa nthawi yayitali, pampu yamafuta iyenera kuyatsidwa masiku 10 aliwonse kapena kupitilira apo kuti zitsimikizire kuti pali mafuta opaka m'malo onse a kompresa. Nthawi iliyonse pampu yamafuta imatsegulidwa kwa mphindi 10; kompresa amayatsidwa kamodzi miyezi 2 mpaka 3, ola limodzi lililonse. Onetsetsani kuti zosuntha sizikugwirizana.
7) Musanayambe nthawi iliyonse, ndi bwino kutembenuza compressor kangapo kuti muwone ngati compressor yatsekedwa kapena ayi, ndikugawa mafuta odzola mofanana m'madera onse.
