Unobangela Uhlalutyo Lomonakalo wePiston

Ngokumalunga ne-hydraulic breaker, njengoko sonke sisazi, ipiston yempembelelo iyimfuneko kuluhlu lwezona zinto ziphambili. Ngokumalunga nokungaphumeleli kwepiston, idla ngokuba yeyona nto, kwaye ngokubanzi ibangela ukusilela okukhulu, kwaye iintlobo zokusilela zivela ngokungapheliyo.Ngoko ke, i-HMB iye yashwankathela izizathu ezininzi zokungaphumeleli kwepiston.

1.Imikrwelo kumphezulu osebenzayo,i-Piston strain crack

Isizathu:

● ubunzima obuphantsi komhlaba

Sebenzisa umvavanyi wobulukhuni ukulinganisa ukuqina kombindi (35 ≥ 45 lixabiso lekhefu elamkelekileyo lobunzima) ③Ukuba ingaphantsi kunedigri ezingama-35 okanye ngaphezulu kweedigri ezingama-20, iipistons ezinkulu, ngakumbi izaphuli zehydraulic ezinamandla amakhulu okuchaphazeleka, ziqhelene kakhulu neentanda zomphezulu ④ Emva kokuqhekeka kuvela kwisiqhelo seshumi, ukutshabalalisa ucingo oluqhelekileyo luya kwandiswa. Umsantsa phakathi kwepiston kunye necylinder, kubangela ubunzima obukhulu.

● Ukungcola okuxutywe kwi-oyile yehydraulic

● Umsantsa phakathi komkhono wesikhokelo se-drill rod (amatyholo aphezulu nangaphantsi) mkhulu kakhulu, kwaye umkhono wesikhokelo uyasilela.

Xa i-drill rod isebenza, i-axis iyancipha. Xa ipiston ibetha intonga ye-drill, ifumana i-reaction force ethambekele, enokuthi ibolise amandla e-axial kunye ne-radial force, kwaye i-radial force inokutyhalela ipiston kwelinye icala, i-gap yokuqala iyanyamalala, ifilimu yeoli iyatshatyalaliswa, ukungqubuzana okomileyo kwenziwa phakathi kwe-cylinder kunye nomphezulu wepiston, kwaye umphezulu wepiston uyakrweleka ngenxa yoko.

2.ukuqhekeka kwepiston

isizathu:

①Ingxaki yezinto eziphathekayo

I-carburized low-alloy steel piston yimbangela yangaphakathi yempembelelo ekupheleni kobuso bokudandatheka kunye nokuqhekeka.

Umahluko wobulukhuni phakathi kwendawo ebetha ipiston kunye nenxalenye ebethayo yentonga yokomba kufuneka ifaneleke.

②Ingxaki yonyango lobushushu

Ngethuba lokunyangwa okanye ukutshisa ukushisa, i-piston material ivelisa ukuqhekeka, okwandisa ukukrazula kude kube kuphulwe phantsi kwesenzo sokutshintshana koxinzelelo.

3.I-piston inomgodi onzulu, kunye nomzimba we-cylinder une-point-to-point symmetrical longitudinal strain;

Isizathu:

① Ukungena ukungcola, okubangela ukuba ipiston ilahlekelwe yibhalansi ngaphambili nangasemva, ngombono wokuthambeka intloko, kubangela ubunzima.

② I-Cavitation, i-cavitation iyenzeka ngokubanzi kwi-cylinder, kungekhona kwi-piston. I-Cavitation iya kubangela umgodi omnyama onzulu, kwaye izinto ezigqithisileyo kuyo ziya kuchithwa kwimpembelelo ekhawulezayo yeoli ye-hydraulic, kwaye yonke i-cylinder iya kunyanzeliswa.

③Imingxuma yomhlwa, njengoko kubonisiwe emfanekisweni ayingomhlwa. Imingxunya yomhlwa ngokuqhelekileyo ibangelwa yi-piston material (umzekelo, abanye abavelisi basebenzisa i-42CRMO okanye basebenzise nje i-40CR kunye nezinye izinto ngenxa yoxinzelelo lwemarike) okanye xa ugcina, abazange banikele ingqalelo ekutyhaleni ipiston kwi-cylinder. Ngeentsuku zemvula, iCorrosion ibangwa ixesha elide, kwaye umhlwa otyheli ujika ube ngumhlwa omnyama kwaye ekugqibeleni ube ngumngxuma. Ngokuqhelekileyo, le nto ixhaphake kwii-breaker ezincinci kunye ezincinci eziqala ukuvuza ioli ngaphambi kwexesha lokugcinwa.

UKUBA unento, nceda uzive ukhululekile ukuqhagamshelana nathi! Masiyisombulule ingxaki kunye, yiza!!
