Chifukwa Kusanthula kwa Piston Kuwonongeka

Pankhani ya hydraulic breaker, monga tonse tikudziwa, pisitoni yamphamvu ndiyofunikira kwambiri pamndandanda wazinthu zazikulu kwambiri.Ponena za kulephera kwa pisitoni, nthawi zambiri kumakhala kopambana, ndipo nthawi zambiri kumayambitsa zolephera zazikulu, ndipo mitundu ya zolephera imatuluka mosalekeza.

1.Zikwapula pamalo ogwirira ntchito, Piston strain crack

Chifukwa chake:

● kuuma kwapansi pamtunda

Gwiritsani ntchito tester yolimba kuti muyeze kuuma kwa pachimake (35 ≥ 45 ndiye mtengo wovomerezeka wanthawi yayitali) ③Ngati ndi wotsika kuposa madigiri 35 kapena kuposa madigiri 20 okha, ma pistoni akulu, makamaka ma hydraulic breakers okhala ndi mphamvu yayikulu, amakhala makamaka sachedwa kung'ambika pamwamba ④ Pambuyo ming'alu kuwonekera, kulolerana mbali imodzi kumawonjezeka mu mawaya makumi ambiri, potero kuwononga kusiyana kwapakati pakati pa pisitoni ndi silinda, zomwe zimayambitsa kupsyinjika kwakukulu.

● Zonyansa zosakanikirana ndi mafuta a hydraulic

● Mpata pakati pa zoboolera ndodo (zitsamba zakumtunda ndi zapansi) ndi waukulu kwambiri, ndipo dzanja lolondolera limalephera.

Pamene ndodo yobowola ikugwira ntchito, axis imapendekera.Pamene pisitoni igunda ndodo yobowola, imalandira mphamvu yowonongeka, yomwe imatha kuwola mphamvu ya axial ndi mphamvu yozungulira, ndipo mphamvu yamagetsi imatha kukankhira pisitoni kumbali imodzi, kusiyana koyambirira kumasoweka, filimu yamafuta imawonongeka, youma. kukangana kumapangidwa pakati pa silinda ndi pisitoni pamwamba, ndipo pisitoni pamwamba pake imakanda chifukwa chake.

2.piston kusweka

chifukwa chake:

①Vuto lazinthu

Pistoni yachitsulo ya carburized low-alloy steel ndiye chifukwa chamkati chakumapeto kwa kukhumudwa kwa nkhope ndi kusweka.

Kusiyana kwa kuuma pakati pa gawo lomenya pisitoni ndi kulimba kwa ndodo yobowola kuyenera kukhala koyenera.

②Kutentha mankhwala vuto

Panthawi yopangira kapena kutentha, pisitoni imatulutsa ming'alu, yomwe imakulitsa ming'aluyo mpaka itasweka chifukwa cha kupsinjika kosinthana.

3.Pistoni ili ndi dzenje lakuya, ndipo thupi la silinda limakhala ndi vuto lofanana ndi longitudinal longitudinal point-to-point;

Chifukwa chake:

①Kulowetsa zonyansa, zomwe zimapangitsa kuti pisitoni iwonongeke kutsogolo ndi kumbuyo, ndi lingaliro lopendekeka mutu, kuchititsa kupsyinjika.

② Cavitation, cavitation nthawi zambiri imapezeka mu silinda, osati pa pistoni.Cavitation idzayambitsa dzenje lakuda lakuya, ndipo zowonjezera zomwe zili mmenemo zidzawonongeka chifukwa chachangu cha mafuta a hydraulic, ndipo silinda yonse idzaphwanyidwa.

③Maenje a dzimbiri, monga momwe akusonyezera pachithunzipa si maenje a dzimbiri.Maenje a dzimbiri amayamba chifukwa cha pisitoni (mwachitsanzo, opanga ena amagwiritsa ntchito 42CRMO kapena amangogwiritsa ntchito 40CR ndi zinthu zina chifukwa cha kukakamizidwa kwa msika) kapena posunga, sanamvere kukankhira pisitoni mu silinda.M'masiku amvula, dzimbiri limayamba kwa nthawi yayitali, ndipo dzimbiri lachikasu limasanduka dzimbiri lakuda ndipo pamapeto pake limasanduka dzenje.Nthawi zambiri, izi ndizofala kwa ma breaker ang'onoang'ono komanso ang'onoang'ono omwe amayamba kutulutsa mafuta nthawi yokonza isanakwane.

NGATI muli ndi kalikonse, chonde omasuka kulankhula nafe! Tiyeni tithetse vutoli limodzi, bwerani!!
