Kodi ntchito ya Excavator Idler ndi yotani?

1- Kuthamanga kwapampu kwakukulu ndi kochepa
PC200-6 excavator utenga awiri swash mbale mtundu axial variable piston mpope.Kukonza ndi kukonza zofukula Munthawi zonse, kutulutsa kwamafuta pampu yayikulu kumakhala kwakukulu kuposa kapena kofanana ndi 30 MP yaying'ono.

Ngati kuchuluka kwa kuvala pakati pa plunger ya pampu yayikulu ndi thupi la silinda kapena pakati pa nkhope yomaliza ya thupi la silinda ndi mbale ya valve kupitilira muyezo (mpata pakati pa plunger ndi thupi la silinda uyenera kukhala wosakwana 0.02, ndi kusiyana pakati pa mbali yomaliza ya thupi la silinda ndi mbale ya valve iyenera kukhala yosakwana 0.02).Malo okhudzana nawo sayenera kukhala osachepera 90%), zomwe zidzachititsa kuti mphamvu yotulutsa pampu yaikulu ikhale yochepa, yomwe idzawonetsedwe mu chipangizo chogwirira ntchito cha makina, ndipo makina onse sangathe kugwira ntchito.

2- Gulu lalikulu la valavu yotulutsa pampu yotulutsa ndi lolakwika
Poganizira kuti mphamvu ya mpope yayikulu ndi injini imatha kufananizidwa bwino ndipo gawo la injini litha kugwiritsidwa ntchito mokwanira, kutuluka kwa mpope waukulu wa makinawo kumasintha ndikusintha kwa mphamvu ya injini.Ngati gulu la valve lowongolera lomwe limagwiritsidwa ntchito kuti lisinthire kutulutsa kwa pampu yayikulu likulephera, ngati cholumikizira cha PLS chatsekedwa, valavu ya LS yatsekedwa, valavu ya PC yakhazikika, kapena coil yamkati ya P ° C-EPC. valavu ya solenoid imawotchedwa Nthawi zina, pampu yaikulu imakhala nthawi zonse.

Ngati pampu yayikulu nthawi zonse imakhala yoyenda pang'ono, makinawo amakhala ofooka komanso odekha pogwira ntchito:
Mofananamo, ngati mbale ya swash, pistoni ya servo ndi mbali zina za mpope waukulu zomwe zimayendetsa mwachindunji kusintha kwa pampu yaikulu zimamatira, kutuluka kwa pampu yaikulu sikungasinthe.

3- Kutulutsa kwamphamvu kowongolera ndi valavu yochepetsera kuthamanga ndikotsika
Nthawi zonse, valavu yochepetsera mphamvu ya kampani yokonza zofukula ku Chongqing imatha kuchepetsa ndikukhazikitsa mphamvu yamafuta a pampu yayikulu pa 3.3P, ndikupanga kuthamanga kwamafuta.Ngati kukankhira spool pa valavu yochepetsera kuthamanga sikutsekedwa mwamphamvu chifukwa mafuta ndi onyansa kwambiri, kutulutsa kwa valve yochepetsera kuthamanga kumakhala kotsika kuposa 3.3MPā.Panthawiyi, ziribe kanthu momwe chogwirira ntchito chimayendera, kuthamanga kwa mafuta olamulira kumakhala kochepa nthawi zonse, ndipo kayendedwe ka spool ka valve yaikulu ya zida zosiyanasiyana zogwirira ntchito ndi yaying'ono, zomwe zimapangitsa kuti pakhale kuyenda pang'ono kwa zipangizo zogwirira ntchito, zomwe zimapangitsa kusowa mphamvu kwa makina onse.

4-Kupumira kwa valve yayikulu yothandizira
Valavu yayikulu yothandizira yokhala ndi mphamvu yochepa imachepetsa kupanikizika kwakukulu kwa ma hydraulic system mpaka 32.5MP.Kwa kuthamanga kwapamwamba kupitirira chiŵerengero, valavu yaikulu yothandizira idzatsegulidwa kuti muchepetse kupanikizika.Hitachi Excavator Repair Chongqing Company idzateteza dongosolo kuti lisawonongeke.Ngati dzenje laling'ono pa spool yaikulu yothandizira valavu yatsekedwa chifukwa cha khalidwe losauka la mafuta ndipo spool nthawi zambiri imatsegulidwa, kapena kupanikizika kwapadera kwa valve yaikulu yothandizira kumakhala kochepa, kupanikizika kwenikweni kudzakhala kochepa, ndiko kuti, dongosolo. Kupanikizika ndi kochepa.

5- Vavu yotsitsa ndi yolakwika
Pamene dalaivala ayambitsa injini ndikuyika chiwombankhanga chosalowerera ndale, mafuta a hydraulic amachokera ku pampu yayikulu amabwerera mwachindunji ku tanki yamafuta kudzera mu valve yotsitsa, ndipo kuthamanga kwa 3MP.Ngati spool ya valavu yotsitsa sichikutsekedwa mwamphamvu chifukwa cha mafuta onyansa, mafuta otuluka pampu yaikulu adzadutsa mu valve yotsitsa mwachindunji ku tanki ya mafuta pamene makina akugwira ntchito.Pamene chisindikizo cha O-ring pa valve yonyamula katundu chomwe chimagwiritsidwa ntchito kuletsa kugwirizana pakati pa mafuta othamanga a PS ndi thanki ya mafuta yawonongeka, zidzachititsanso kuti pampu yaikulu ya hydraulic mafuta abwerere ku thanki ya mafuta mwachindunji.

6-LS bypass valve yolakwika
Valavu ya LS yodutsa imatha kutulutsa gawo la mafuta oponderezedwa a P15 pagawo la LS kudzera m'mabowo ang'onoang'ono ang'onoang'ono pathupi la valve (pang'ono) kuti awonjezere kukhazikika kwa makinawo.Ngati chisindikizo cha O-ring pa thupi la valavu chawonongeka, mafuta othamanga a PL5 adzalankhulana mwachindunji ndi thanki yamafuta, zomwe zidzachititsa kuti valavu yotsegula ikhale yotseguka bwino, zomwe zimapangitsa kuti pakhale kufooka komanso kuyenda pang'onopang'ono kwa chipangizo chilichonse chogwira ntchito.

Mwachidule, ngati chofukula cha PC200-6 sichingathe kugwira ntchito yonse, zitha kukhala chifukwa cha mafuta osakwanira amafuta a hydraulic.Choncho, m'malo hydraulic mafuta fyuluta chinthu pa nthawi (chofunika kusinthidwa 500 iliyonse) ndi kulabadira kuchira.
