Valve Yapamwamba Yotumizira K15 ya Injection Pump Diesel Engine Spare Parts ya ISUZU KUBOTA ISEKI

1. Mapangidwe a valve yoperekera

(1) Vavu yobweretsera mafuta ndi mpando wa valve ndi mbali zolondola, zopangidwa ndi chitsulo chapamwamba kwambiri. Mabowo awo owongolera, kumtunda ndi kumunsi kumapeto ndi mabowo amipando amakonzedwa molondola ndi pansi, ndipo sangasinthidwe pambuyo polumikizana.

(2) Gawo la cone la valve yotulutsira mafuta ndi gawo la axial losindikiza pamwamba pa valavu. Mbali ya cone ya valavu imalowa mu dzenje la kalozera ndipo imagwira ntchito yotsogolera. Mchirawo umapangidwa ndi ma grooves kuti apange gawo lopingasa kuti mafuta adutse. Pamwamba pa cylindrical pakatikati pa valavu yoperekera mafuta amatchedwa decompression zone, yomwe imapanga voliyumu ya decompression yokhala ndi chosindikizira chosindikizira.

(3) Pansi pamunsi pampando wa valve ndi chapamwamba chakumtunda kwa manja a plunger amapangidwa mwaluso ndikumangika mwamphamvu. Amamangika ndi nati wa compression ndi torque yomwe yatchulidwa. Pali chotsukira chosindikizira chamkuwa cha makulidwe ena ake pakati pa nati woponderezedwa ndi mpando wa valve. Palinso gasket yosindikizira yotsika kwambiri pakati pa nati wamagetsi operekera mafuta ndi kumtunda kwa nyumbayo.

(4) Chidebe chochepetsera chotsekera chimayikidwa mkati mwa valavu yoperekera mafuta kuti muchepetse kuchuluka kwa danga lamkati, kulimbikitsa kuyimitsa jekeseni mwachangu, ndikuchepetsa kukweza kwa valve yotulutsa mafuta.

2. Ntchito ya valve yoperekera

(1) Pewani kudontha kwamafuta musanabayidwe ndikuwonjezera liwiro la jekeseni: Pamene pampu ya jakisoni yamafuta imatulutsa mafuta, kupanikizika kwamafuta kukakwera kuposa mphamvu yodzaza masika a valve yoperekera mafuta komanso kupanikizika kotsalira mu chitoliro chamafuta othamanga kwambiri, valavu yotulutsira mafuta Vavu yamafuta imakwera ndipo chosindikizira chake chimachoka pampando wa valve. Ndikofunikira kudikirira mpaka gulu lothandizira kupanikizika pa valavu yoperekera mafuta litasiya kwathunthu dzenje lowongolera la mpando wa valavu mafuta asanayambe kulowa mupaipi yamafuta othamanga kwambiri.

(2) Pewani kudontha kwa mafuta pambuyo pa jekeseni ndikuwonjezera liwiro lotseka: Mafuta akayimitsidwa, m'mphepete mwa m'mphepete mwa lamba wotulutsa mafuta amalowa munjira, njira yapakati pa chitoliro chamafuta othamanga kwambiri. ndi mpope wadulidwa. Vavu yoperekera mafuta ikakhazikika, imatsika mtunda h, motero kuchuluka kwa chitoliro chamafuta othamanga kwambiri kumawonjezeka, zomwe zimapangitsa kuti kuthamanga kwamafuta kugwere mwachangu ndi 1MPa ~ 2MPa, ndipo mafuta amadulidwa mwachangu komanso mophweka, kuletsa kusinthasintha kwa kuthamanga kwa mafuta komanso "kuchepa kwa mapaipi" kuti asapangitse mafuta kukwera. (3) Pewani mafuta kuti asabwerere mmbuyo ndikusunga kupanikizika kotsalira mu chitoliro chamafuta chothamanga kwambiri.
