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 kune 35 degrees okanye nangaphezulu kwe 20 degrees, iipistons ezinkulu, ingakumbi iziqhekeza zehydraulic ezinempembelelo enkulu yamandla, ngakumbi ethanda ukuqhekeka komphezulu ④ Emva kokuvela kweentanda, ukunyamezela kwelinye icala kuya kwanda kumashumi eingcingo, ngaloo ndlela kutshatyalaliswe umsantsa oqhelekileyo phakathi kwepiston kunye necylinder, oko 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 i-piston ibetha intonga ye-drill, ifumana amandla okusabela okuthambekele, anokubola amandla e-axial kunye ne-radial force, kwaye i-radial force inokutyhala ipiston kwelinye icala, i-gap yokuqala iyanyamalala, ifilimu yeoli iyatshatyalaliswa, yomile. Ukungqubuzana kwenziwa phakathi kwe-cylinder kunye nomphezulu wepiston, kwaye umphezulu wepiston uyakrweleka ngenxa yoko.
2.ukwaphuka 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!!
