1. Kuyambitsa Koyamba ndi Kutseka
Musanayambe makina, cholumikiziracho chiyenera kukonzedwanso. Musanayambe makina koyamba, yang'anani momwe zigawo zonse za compressor ndi zida zamagetsi zimagwirira ntchito.
Zinthu zowunikira ndi izi:
Yatsani switch yoyatsira magetsi ndikuyika switch yosankha pamalo amanja;
Dinani batani la alamu; alamu idzalira; dinani batani loletsa kutseka; alamu idzalira;
Dinani batani la chotenthetsera chamagetsi; nyali yowunikira idzaunikira. Mukatsimikizira kuti chotenthetsera chamagetsi chikugwira ntchito, dinani batani loyimitsa kutentha; nyali yowunikira kutentha idzazima;
Dinani batani loyatsira pampu yamadzi; pampu yamadzi ikuyamba; nyali yowunikira idzaunikira. Dinani batani loyatsira pampu yamadzi; pampu yamadzi iyamba; nyali yowunikira idzazima;
Dinani batani loyambira pampu yamafuta; kuwala kowonetsa pampu yamafuta kudzawala, ndipo pampu yamafuta ikuyenda ndikuzungulira mbali yoyenera. Sinthani kusiyana kwa kuthamanga kwamafuta kukhala 0.4-0.6 MPa.
Sunthani valavu ya njira zinayi kapena dinani batani lowonjezera/kuchepetsa katundu kuti muwone ngati valavu yotsatsira ndi chizindikiro cha mphamvu zikugwira ntchito bwino. Chizindikiro cha mphamvu chiyenera kukhala pa "0." Chongani makonda a ma relay onse odzitetezera okha kapena mapulogalamu.
Chitetezo champhamvu cha kuthamanga kwa utsi: Kuthamanga kwa utsi ≤ 1.57 MPa
Kutentha kwa jakisoni chitetezo chapamwamba: Kutentha kwa jakisoni ≤ 65°C
Kusiyanitsa kwa kuthamanga kwa mafuta chitetezo chochepa: Kusiyanitsa kwa kuthamanga kwa mafuta ≥ 0.1 MPa
Chitetezo champhamvu cha kusiyana kwa kuthamanga kwa mpweya musanayambe komanso mutatha fyuluta yaying'ono: Kusiyana kwa kuthamanga kwa mpweya ≤ 0.1 MPa
Chitetezo chochepa cha kuthamanga kwa magazi: Chimakhazikitsidwa malinga ndi momwe zinthu zilili.
Pambuyo poyang'ana zinthu zomwe zili pamwambapa, chipangizocho chikhoza kuyambika. Masitepe oyambira ndi awa:
1) Sankhani switch yoyambira pamanja.
2) Tsegulani valavu yotseka mpweya wa compressor.
3) Tulutsani compressor pamalo a "0", mwachitsanzo, 10% ya katundu.
4) Yambitsani pampu yamadzi yozizira ndi pampu yamadzi yoziziritsira kuti mupereke madzi ku condenser, mafuta ozizira, ndi evaporator.
5) Yambitsani pompu yamafuta.
6) Masekondi 30 pambuyo poti pampu yamafuta yayamba, ndipo kusiyana kwa kuthamanga kwa mafuta pakati pa kuthamanga kwa mafuta ndi kuthamanga kwa utsi kufika pa 0.4-0.6 MPa, dinani batani loyambira compressor. Compressor idzayamba, ndipo valavu ya solenoid A idzatsegulidwa yokha. Motowo ukayamba kugwira ntchito bwino, valavu A idzatseka yokha.
7) Yang'anirani choyezera kuthamanga kwa madzi, tsegulani pang'onopang'ono valavu yotseka madzi, ndikuwonjezera katundu pamanja, samalani kuti kuthamanga kwa madzi kusamatsike kwambiri. Compressor ikayamba kugwira ntchito bwino, sinthani valavu yowongolera kuthamanga kwa madzi kuti mafuta azikhala ndi kuthamanga kwa 0.15-0.3 MPa.
8) Yang'anani kuthamanga ndi kutentha kwa ziwalo zonse za chipangizocho, makamaka za ziwalo zoyenda, kuti zigwire ntchito bwino. Ngati pali vuto lililonse, tsekani chipangizocho kuti chiziyang'aniridwe.
9) Kugwira ntchito koyamba sikuyenera kukhala kwa nthawi yayitali; pafupifupi theka la ola ndi kokwanira. Njira yozimitsa ndi kutsitsa zida, kuzimitsa injini yayikulu, kutseka valavu yozimitsa yoyatsira, kuyimitsa pampu yamafuta, kenako kuyimitsa pampu yamadzi, ndikumaliza njira yoyambira. Kukanikiza batani lalikulu loyimitsa injini kumatsegula valavu ya bypass solenoid B. Vavu B imatseka yokha ikazima.
2. Kuyambitsa ndi Kutseka Kwachizolowezi: Njira yoyambira yachizolowezi ndi iyi:
a. Sankhani kuyambitsa pamanja, komwe kuli kofanana ndi njira yoyamba yoyambira.
b. Sankhani kuyambitsa kokha
1) Tsegulani valavu yotseka utsi wa compressor ndikuyambitsa pampu yamadzi ozizira ndi pampu yoziziritsira. 2) Dinani batani loyambira compressor. Pampu yamafuta iyamba kugwira ntchito yokha ndipo valavu yosunthira idzabwerera yokha pamalo a "0". Pambuyo poti kusiyana kwa kuthamanga kwa mafuta kwakhazikika, mota yayikulu iyamba yokha pambuyo pa kuchedwa kwa masekondi pafupifupi 15, ndipo valavu ya bypass solenoid A idzatsegulidwa yokha. Motowo ukayamba kugwira ntchito bwino, valavu A idzatseka yokha. 3) Motowo ukayamba kugwira ntchito bwino, tsegulani pang'onopang'ono valavu yotseka yotsamira nthawi imodzi. Kupanda kutero, vacuum yambiri idzawonjezera kugwedezeka ndi phokoso la makina. 4) Kompresa idzawonjezera katundu mpaka 100% ndikulowa mu ntchito yanthawi zonse. Malo onyamula katundu adzasintha yokha malinga ndi malo oyika kuthamanga kapena malo oyika kutentha kwa firiji.
Njira yozimitsa yachizolowezi ndi iyi: a. Kuzimitsa kwamanja: Mofanana ndi njira yoyamba yoyambira. b. Ndi switch yosankha yomwe ili pamalo odziyimira yokha: 1) Dinani batani loyimitsa compressor. Valavu yosunthira imabwerera yokha pamalo a "0", mota yayikulu imayima yokha, ndipo valavu ya bypass solenoid B imatsegulidwa yokha. Pampu yamafuta imayima yokha pambuyo pochedwa. Pambuyo pozimitsa, valavu B imatseka yokha. 2) Tsekani valavu yoyimitsa suction. Ngati makinawo azimitsidwa kwa nthawi yayitali, valavu yoyimitsa utsi iyeneranso kutsekedwa. 3) Zimitsani mphamvu ya pampu yamadzi ndi maswichi a mphamvu ya compressor.
3. Zosamala panthawi ya opaleshoni
(1) Pa nthawi yogwira ntchito ya compressor, samalani kuti muwone momwe mphamvu yokoka ndi utsi imagwirira ntchito, kutentha kwa mphamvu yokoka ndi utsi imagwirira ntchito, kutentha kwa mafuta ndi utsi imagwirira ntchito, ndipo muzilembe nthawi zonse. Chidacho chiyenera kukhala cholondola.
(2) Ngati compressor imasiya yokha chifukwa cha chitetezo chachitetezo panthawi yogwira ntchito, chifukwa cha vuto chiyenera kupezeka musanayambitsenso. Sichiloledwa kuyambiranso mwa kusintha ma values awo kapena kuteteza vutolo.
(3) Pamene chipangizo chachikulu chayima chifukwa cha kuzimitsa kwa magetsi mwadzidzidzi, valavu ya bypass solenoid B singathe kutsegulidwa, ndipo compressor ikhoza kubwerera m'mbuyo. Panthawiyi, valavu yoyimitsa suction iyenera kutsekedwa mwachangu kuti muchepetse kubwerera m'mbuyo.
(4) Ngati makinawo azimitsidwa kwa nthawi yayitali mu nyengo yomwe kutentha kwake kuli kochepa, madzi onse omwe ali mu makinawo ayenera kuchotsedwa kuti asawononge zidazo ndi kuzizira.
(5) Ngati makina ayambitsidwa mu nyengo yotentha yochepa, yambani choyamba pampu yamafuta ndikukanikiza mota kuti izungulire chiwongolero kuti musunthe cholumikizira kuti mafuta azizungulira mu compressor kuti mafuta azikhala okwanira. Njirayi iyenera kuchitika munjira yoyambira ndi manja; ngati ndi Freon refrigerant, chotenthetsera mafuta chiyenera kuyatsidwa kuti chitenthe mafuta odzola musanayambe makinawo, ndipo kutentha kwa mafuta kuyenera kutsimikizika kuti kuli pamwamba pa 25℃.
(6) Ngati chipangizocho chatsekedwa kwa nthawi yayitali, pampu yamafuta iyenera kuyatsidwa masiku 10 aliwonse kapena kuposerapo kuti ziwiya zonse za compressor zipakidwe mafuta. Pampu yamafuta ikhoza kuyatsidwa kwa mphindi 10 nthawi iliyonse. Pampu yamafuta iyenera kuyatsidwa miyezi iwiri kapena itatu iliyonse kwa ola limodzi nthawi iliyonse kuti ziwiya zosuntha zisamamatire pamodzi.
(7) Musanayambe chipangizochi nthawi iliyonse, ndi bwino kuzunguliza compressor kangapo kuti muwone ngati compressor yakhazikika ndikuwonetsetsa kuti mafuta opaka mafuta akugawidwa mofanana m'mbali zonse.
