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 kuuma kuyeza kuuma kwa pachimake (35 ≥ 45 ndiye chovomerezeka kuuma kwanthawi mtengo) ③ Ngati ndi wotsika kuposa madigiri 35 kapena kuposa madigiri 20 okha, ma pistoni akuluakulu, makamaka ma hydraulic breakers okhala ndi mphamvu yayikulu kwambiri, amakhala sachedwa kung'ambika pamwamba ④ Pambuyo ming'alu ikuwonekera, ming'alu ikuwoneka pambali imodzi, kuwononga waya. kusiyana pakati pa pisitoni ndi silinda, kuchititsa 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 yozungulira imatha kukankhira pisitoni kumbali imodzi, kusiyana koyambirira kumasowa, filimu yamafuta imawonongeka, kukangana kowuma kumapangidwa pakati pa silinda ndi pisitoni, ndipo pisitoni 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, zomwe zimayambitsa mavuto.

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!!
