1.Yambani ndi kuyimitsa koyamba
Musanayambe, cholumikiziracho chiyenera kukonzedwanso. Mukayamba koyamba, choyamba muyenera kuyang'ana momwe zinthu zonse za compressor ndi zida zamagetsi zimagwirira ntchito.
Zinthu zowunikira ndi izi:
a. Tsekani switch yamagetsi ndikusankha malo amanja a switch yosankha;
b. Dinani batani la alamu, belu la alamu lidzalira; dinani batani loletsa, alamu idzachotsedwa;
c, Dinani batani lotenthetsera lamagetsi ndipo nyali yowunikira yayatsidwa. Mukatsimikizira kuti chotenthetsera chamagetsi chikugwira ntchito, dinani batani loyimitsa kutentha ndipo nyali yowunikira kutentha yazimitsidwa;
d. Dinani batani loyatsira pampu yamadzi, pampu yamadzi ikuyamba, nyali yowunikira yayatsidwa, dinani batani loyimitsa pampu yamadzi, pampu yamadzi imasiya, ndipo nyali yowunikira yayatsidwa;
e. Dinani batani loyambira la pampu yamafuta, kuwala kosonyeza mphamvu ya pampu yamafuta kukuyaka, pampu yamafuta ikuyenda ndikuzungulira mbali yoyenera, ndipo kusiyana kwa kuthamanga kwa mafuta kukusinthidwa kukhala 0.4 ~ 0.6MPa. Sinthani valavu ya njira zinayi kapena dinani batani lowonjezera/kuchepetsa mphamvu kuti muwone ngati valavu yosunthira ndi chipangizo chosonyeza mphamvu zikugwira ntchito bwino, ndipo chizindikiro chomaliza cha mphamvu chili pamalo a "0".
Chongani mtengo wokhazikika wa pulogalamu iliyonse yodzitetezera yokha kapena pulogalamu/Mtengo wofotokozera kutentha kwa compressor ndi chitetezo cha kuthamanga:
a. Chitetezo cha kuthamanga kwambiri kwa utsi: kuthamanga kwa utsi≦1.57MPa
b. Chitetezo cha kutentha kwambiri cha jakisoni wa mafuta: kutentha kwa jakisoni wa mafuta ≦65℃
c. Chitetezo cha kusiyana kwa kuthamanga kwa mafuta: kusiyana kwa kuthamanga kwa mafuta ≧0.1MPa
d. Chitetezo cha kusiyana kwa kuthamanga kwa mpweya musanayambe komanso mutatha fyuluta yaying'ono: kusiyana kwa kuthamanga kwa mpweya ≦0.1MPa
e. Chitetezo chochepa cha kuthamanga kwa magazi: chikugwirizana ndi momwe zinthu zilili pa ntchito
Mukayang'ana zinthu zomwe zili pamwambapa, mutha kuziyatsa
Njira zoyatsira ndi izi:
a. Chosinthira chosankha chimayatsidwa pamanja;
b. Tsegulani valavu yozimitsa mpweya ya compressor;
c. Tulutsani compressor pamalo a "0", omwe ndi malo okwana 10% a katundu;
d. Yambitsani pampu yamadzi yozizira ndi pampu yamadzi yoziziritsira kuti mupereke madzi ku condenser, mafuta oziziritsira ndi evaporator;
e. Yambitsani pompu yamafuta;
f. Masekondi 30 pambuyo poti pampu yamafuta yayamba, kusiyana pakati pa kuthamanga kwa mafuta ndi kuthamanga kwa kutulutsa kumafika pa 0.4 ~ 0.6MPa, dinani batani loyambira compressor, compressor imayamba, ndipo valavu ya bypass solenoid A imatsegukanso yokha. Pambuyo poti mota ikuyenda bwino, valavu ya A imatsekedwa yokha;
g. Yang'anirani choyezera kuthamanga kwa mafuta, tsegulani pang'onopang'ono valavu yoyimitsa kupopera madzi ndikuwonjezera katundu pamanja, ndipo samalani kuti kuthamanga kwa madzi kusakhale kotsika kwambiri. Compressor ikayamba kugwira ntchito bwino, sinthani valavu yowongolera kuthamanga kwa mafuta kuti kusiyana kwa kuthamanga kwa mafuta kukhale 0.15 ~ 0.3MPa.
h. Onetsetsani ngati kuthamanga ndi kutentha kwa gawo lililonse la chipangizocho, makamaka kutentha kwa zida zoyenda, ndi kwabwinobwino. Ngati pali vuto lililonse, imitsani makinawo kuti akawone.
i. Nthawi yoyamba yogwirira ntchito siyenera kukhala yayitali kwambiri, ndipo makinawo akhoza kuzimitsidwa mkati mwa theka la ola. Kuzimitsidwa kwa makina kukutsitsa, kuyimitsa wolandila, kutseka valavu yozimitsira, kuyimitsa pampu yamafuta, ndikuyimitsa pampu yamadzi kuti amalize njira yoyamba yoyambira. Batani lalikulu loyimitsa injini likakanikiza, valavu ya bypass solenoid B imatsegulidwa yokha, ndipo valavu B imatsekedwa yokha pambuyo pozimitsidwa.
2. Kuyambitsa kwachizolowezi ndi kutseka
Kuyamba kwabwinobwinondimotere:
Sankhani boot yamanja, njira yake ndi yofanana ndi boot yoyamba.
Sankhani kuyatsa yokha:
1) Tsegulani valavu yotseka utsi wa compressor, yambani pampu yamadzi ozizira ndi pampu yamadzi yoziziritsira;
2) Dinani batani loyambira compressor, kenako pampu yamafuta idzayamba kugwira ntchito yokha, ndipo valavu ya spool idzabwerera yokha pamalo a "0". Pambuyo poti kusiyana kwa kuthamanga kwa mafuta kwakhazikika, mota yayikulu idzayamba yokha pambuyo pa kuchedwa kwa masekondi pafupifupi 15, ndipo valavu ya bypass solenoid A idzatsegulidwa yokha nthawi yomweyo. Motowo ukayamba kugwira ntchito bwino, valavu ya A imatsekedwa yokha;
3) Mota yayikulu ikayamba kuyaka, valavu yotseka mphamvu ya suction iyenera kutsegulidwa pang'onopang'ono nthawi yomweyo, apo ayi vacuum yochuluka kwambiri idzawonjezera kugwedezeka ndi phokoso la makina.
4) Kompresa idzawonjezera katunduyo mpaka 100% ndikulowa mu mkhalidwe wabwinobwino wogwirira ntchito. Ndipo imasintha yokha malo ogwirira ntchito malinga ndi mtengo wokhazikitsa kupanikizika kapena mtengo wokhazikitsa kutentha kwa firiji.
Njira yodziwika bwino yotseka ndi iyi:
Kutseka kwamanja ndikofanana ndi njira yozimitsa ya oyambitsa oyamba.
Chosinthira chosankha chili pamalo odziyimira pawokha:
1) Dinani batani loyimitsa compressor, valavu yosunthira idzabwerera yokha pamalo a "0", mota yayikulu idzayima yokha, ndipo valavu ya bypass solenoid B idzatsegulidwa yokha nthawi yomweyo, pampu yamafuta idzayima yokha pambuyo pochedwa, ndipo valavu ya B idzatseka yokha ikayima;
2) Tsekani valavu yoyimitsa kupopera. Ngati yazimitsidwa kwa nthawi yayitali, valavu yozimitsira utsi iyeneranso kutsekedwa;
3) Zimitsani chosinthira magetsi cha pampu yamadzi ndi compressor.
3. Zosamala panthawi ya opaleshoni
1) Samalani kuti muwone mphamvu ya kuyamwa ndi kutulutsa madzi, kutentha kwa kuyamwa ndi kutulutsa madzi, kutentha kwa mafuta ndi kuthamanga kwa mafuta panthawi yogwiritsira ntchito compressor, ndipo lembani nthawi zonse. Choyezeracho chikufunika kuti chikhale cholondola.
2) Compressor imayima yokha chifukwa cha chitetezo china chake panthawi yogwira ntchito ya compressor, ndipo chifukwa cha vutoli chiyenera kudziwika isanayatsidwe. Sichiloledwa kuyatsanso posintha makonda awo kapena kuteteza zolakwika.
3) Injini yayikulu ikazima chifukwa cha kulephera kwamphamvu kwadzidzidzi, compressor ikhoza kubwerera m'mbuyo chifukwa valavu ya bypass solenoid B singatsegulidwe. Pakadali pano, valavu yoyimitsa suction iyenera kutsekedwa mwachangu kuti ichepetse kubwerera m'mbuyo.
4) Ngati makinawo atsekedwa kwa nthawi yayitali mu nyengo yotsika kutentha, madzi onse omwe ali mu dongosololi ayenera kuchotsedwa kuti asawononge zidazo ndi kuzizira.
5) Ngati muyambitsa makina munyengo yotsika kutentha, yatsani choyamba pampu yamafuta, ndikukanikiza mota kuti izungulire chiwongolero kuti chiyendetse cholumikizira kuti mafuta azizungulira mu compressor kuti mafuta azikhala okwanira. Njirayi iyenera kuchitika munjira yoyambira ndi manja; ngati ndi Freon refrigerant, yatsani makina Musanayatse chotenthetsera mafuta kuti mutenthe mafuta odzola, kutentha kwa mafuta kuyenera kukhala pamwamba pa 25℃.
6) Ngati chipangizocho chatsekedwa kwa nthawi yayitali, pampu yamafuta iyenera kuyatsidwa masiku 10 aliwonse kapena kuposerapo kuti zitsimikizire kuti pali mafuta odzola m'mbali zonse za compressor. Nthawi iliyonse pampu yamafuta ikayatsidwa kwa mphindi 10; compressor imayatsidwa kamodzi pa miyezi iwiri kapena itatu iliyonse, ola limodzi lililonse. Onetsetsani kuti ziwalo zosuntha sizimamatirana.
7) Musanayambe nthawi iliyonse, ndi bwino kuzunguliza compressor kangapo kuti muwone ngati compressor yatsekedwa kapena ayi, ndikugawa mafuta odzola mofanana m'mbali zonse.
