Daim ntawv thov
Tricone khoom, uas qee tus kuj hu ua cov menyuam lub khob hliav qab lossis cov khoom siv tri-cone, muaj peb lub khob.Txhua lub khob hliav qab tuaj yeem tig ib tus zuj zus thaum lub laum txoj hlua tig lub cev ntawm me ntsis.Lub cones muaj cov menyuam bearings haum thaum lub sijhawm sib dhos.Cov dov txiav cov khoom tuaj yeem siv los laum ib qho kev tsim yog tias xaiv qhov zoo cutter, bearing, thiab nozzle.
Yam ntxwv
1. Lub zog thiab hnav tsis kam ntawm inserts yog txhim kho los ntawm kev siv carbide inserts nrog lub zog siab thiab hnav tsis kam.
2. Nto ntawm lub siab precision bearing kub kho los ntawm kev siv cov txheej txheem kev kho cua sov siab heev los txhim kho lub peev xwm thiab kev pabcuam lub neej ntawm cov kabmob.
3. Lub neej kev pab cuam ntawm cov kabmob yog txuas ntxiv los ntawm kev siv cov khoom siv hnyav dua thiab ntau dua rau cov kabmob thrust.
4. No series roj zoo pob zeb me ntsis siv kaw cov menyuam bearing qauv.Nrog rollers teem rau hauv grooves recessed nyob rau hauv lub khob hliav qab lub cev, qhov luaj li cas ntawm bearing journal yog nce.
6. Thrust bearing nto yog tawv tawv thiab kho nrog kev sib txhuam kom txo cov tshuab.
7. Rotary laum khoom siv phau ntawv xov xwm bearing.Hard faced taub hau bearing nto.Cone bearing inlaid nrog kev sib txhuam txo alloy thiab tom qab ntawd nyiaj-plated.Lub peev xwm thauj khoom thiab kev qaug dab peg ntawm cov kabmob yog zoo heev.
