Chifukwa chiyani Dizilo Jenereta Crankshaft Amachotsedwa

Pa ntchito jenereta ya dizilo , crankshaft sliding bearing imachotsedwa, yomwe imadziwika kuti "tayilo yoyaka".Chifukwa chachikulu cha kulephera kumeneku ndi chakuti pamene makina opangira mafuta ndi mafuta a injini ya dizilo ndi aakulu kwambiri, ndipo mafuta sakukwanira, filimu yabwino ya mafuta odzola sichingapangidwe pakati pa crankshaft magazine ndi chitsamba chonyamula, zomwe zimapangitsa kuti zikhale zolunjika. kukangana pakati pa crankshaft magazine ndi chitsamba choberekera.

1. Zomwe zimayambitsa kuwonongeka kwa crankshaft

(1) Mafuta osakwanira

a.Ubwino wa mafuta a injini ndi osauka;fumbi lalikulu limasakanizidwa mu mafuta a injini pakagwiritsidwe ntchito kwa nthawi yayitali, ndipo mafuta a injini amapangidwa ndi okosijeni ndikuwonongeka chifukwa cha kutentha kwakukulu kwa injini ya dizilo.

b.Pali madzi osakanikirana mu mafuta a injini.Ming'alu mu jekete lamadzi kapena jekete yamadzi imakhala ndi matuza, zomwe zimapangitsa kuti madzi ozizira alowe mumafuta a injini.

c.Mafuta a injini amakhala ochepa.Chifukwa mapampu ena opangira mafuta a injini ya dizilo amatenga mafuta otenthetsera, pompo yojambulira mafuta ikatsekedwa, mafuta a dizilo amalowa munjira yamafuta opaka mafuta kuti achepetse ndikuwononga mafuta opaka injini ya dizilo.

(2) Kuchuluka kwamafuta osakwanira komanso kuthamanga kwamafuta ochepa

a.Kuchuluka kwamafuta sikukwanira.Kulephera kuwonjezera mafuta okwanira molingana ndi zomwe zanenedwa kumapangitsa kuti pakhale mafuta opaka mafuta osakwanira a injini ya dizilo, ndipo kupangidwa kwa filimu yopaka mafuta sikungatsimikizidwe.

b.Kuthamanga kwamafuta ndi kochepa.Chifukwa cha kuchepa kwamafuta, palibe filimu yopaka mafuta yomwe imapangidwa pakati pa crankshaft magazine ndi chitsamba chonyamula.

c.Chifukwa chakusayera bwino kwamafuta a injini, njira yamafuta opaka mafuta kapena dzenje lamafuta limatsekedwa, kapena pali mafuta osakwanira kapena osakwanira a injini pakati pa crankshaft magazine ndi chitsamba chonyamula.

(3) Kusiyana pakati pa crankshaft magazine ndi chitsamba choberekera ndi chachikulu kwambiri kapena chaching'ono kwambiri.

a.Chilolezo pakati pa crankshaft magazine ndi chitsamba chonyamula ndi chachikulu kwambiri kuti chichepetse kuthamanga kwamafuta ndipo ndizosatheka kupanga filimu yokwanira yopaka mafuta.

b.Kusiyana pakati pa crankshaft magazine ndi chitsamba chobereka ndikochepa kwambiri, zomwe zimapangitsa kuti filimu yamafuta ikhale yosakwanira kapena palibe filimu yamafuta opaka mafuta pakati pa crankshaft magazine ndi chitsamba chonyamula.

c.Chitsamba chobereka (camshaft bushing) chimayenda mozungulira.Chifukwa cha kusuntha kwa axial kwa chitsamba chonyamula (camshaft bushing), mapangidwe a chipinda chopondereza mafuta amawonongeka, kupanikizika kwa mafuta sikungapangidwe, ndipo filimu yamafuta opaka mafuta sangathe kupangidwa.

(4) Miyeso ya geometric ya crankshaft kapena cylinder block yatha kulolerana.

A. The crankshaft radial runout (kupindika kwa crankshaft) ndi yayikulu kwambiri, kotero kuti kusiyana pakati pa magazini ndi chitsamba choberekera kumakhala kochepa kapena palibe kusiyana, ndipo makulidwe a filimu yamafuta opaka sikokwanira kapena palibe filimu yamafuta opaka mafuta.

B. Ma angle osagwirizana a crankshaft yolumikiza ndodo ndi makona osafanana a crankshaft yolumikizira ndodo magazini a multicylinder injini ya dizilo imapangitsa kusiyana pakati pa zolumikizira ndodo ndi chitsamba chonyamula chitsamba chochepa kwambiri kapena palibe kusiyana, ndipo makulidwe a filimu yamafuta opaka ndi osakwanira kapena palibe filimu yamafuta opaka mafuta.

C. Kulumikizana kwa dzenje lalikulu la cylinder block ndikosauka kwambiri, zomwe zimapangitsa kuti pakhale kusiyana kochepa kwambiri kapena kusakhalapo pakati pa magazini yayikulu ndi tchire, kusakwanira kwa filimu yamafuta opaka mafuta osakwanira kapena kusakhala ndi filimu yamafuta opaka mafuta.

D. Kuyima kwa dzenje la silinda ndi dzenje lalikulu lonyamulira ndizochepa kwambiri, zomwe zimapangitsa kuti magazini yolumikizira ndodo ndi chilolezo cha shaft chachikulu chikhale chaching'ono kwambiri kapena chopanda chilolezo, makulidwe a filimu yamafuta opaka mafuta osakwanira kapena kusakhala ndi filimu yamafuta opaka mafuta.

(5) Kulondola kwamphamvu kwa crankshaft, flywheel ndi clutch sikuloledwa.

Pamene kulondola kwamphamvu kwamphamvu sikutha kulolerana, kusinthasintha kothamanga kwa crankshaft kumapanga mphamvu zambiri zopanda mphamvu, zomwe zingawononge chilolezo pakati pa crankshaft magazine ndi chitsamba chonyamula.Zikavuta kwambiri, magaziniyo ndi chitsamba choberekera chimakwirira molunjika ku crankshaft ndikuyambitsa kutulutsa kwa crankshaft.

(6) Kusamalira kosayenera.

Injini ya dizilo ikatha kwa nthawi yayitali, ngati kukonzanso koyenera sikunachitike munthawi yake, kumapangitsa kuti pampu yamafuta ikhale yotsekereza valavu, pampu yamafuta ndi magawo ena kuvala, kulephera ndi kupunduka.Chosefera chosefera chamafuta chidzatsekedwa ndi dothi lamafuta ndi matope, zomwe zimachepetsa kuthamanga kwamafuta ndikupangitsa kuti crankshaft iwonongeke.

Ngati muli ndi chidwi ndi ma jenereta a dizilo opanda phokoso , chonde imelo kwa ife mwachindunji: dingbo@dieselgeneratortech.com.
