Lub Secrets Tom qab Hydraulic Drilling Rig Rotation Speeds
Kev sib hloov ceev ntawm tag nrho hydraulic drilling rig yog zoo li lub zog hauv lub tsheb; txawv kev khiav hauj lwm tej yam kev mob yuav tsum tau sib txawv pacing. Qhov kev nrawm nrawm feem ntau poob ntawm 0 thiab 200 kiv puag ncig ib feeb (RPM), txawm hais tias tus nqi tshwj xeeb nyob ntawm peb yam tseem ceeb:
Drill Bit Diameter: Ib qho 200mm me ntsis raug pom zoo ua haujlwm ntawm 30 thiab 60 RPM, qhov 50mm me ntsis tuaj yeem ncav cuag qhov nrawm txog li 150 RPM.
Pob zeb Formation Hardness: Cov pob zeb tawv, xws li granite, yuav tsum tau ceev ceev (20-40 RPM), thaum cov txheej av mos tso cai rau kev nce ceev tshaj 100 RPM.
Hydraulic System Siab: Thaum lub sijhawm ua haujlwm ib txwm muaj, lub kaw lus siab tau khaws cia hauv thaj tsam 15-25 MPa.
Kho qhov kev sib hloov ceev hauv plaub kauj ruam yooj yim
Kho qhov kev sib hloov ceev yog qhov yooj yim dua li kho qhov kub thiab txias ntawm lub tshuab cua txias -koj tsuas yog yuav tsum nco ntsoov cov txheej txheem no:
Kev ntsuas qhov xwm txheej: kwv yees qhov kev sib hloov ceev pib raws li cov qauv ntawm cov pob zeb tsim.
Pib Kev Xeem Drilling: Pib nrog qhov kev sim ua kom ntev li 30 vib nas this ntawm 50% ntawm qhov kwv yees qhov ceev ceev.
Saib Xyuas Cov Lus Qhia: Qhov zoo tshaj plaws, cov pob zeb txiav yuav tsum tsis sib xws hauv qhov loj; yog tias lawv zoo dhau lawm, txo qhov ceev; yog tias lawv ntxhib dhau lawm, ua kom nrawm dua.
Fine-tune thiab Xauv: Txwv txhua qhov kev hloov kho ntxiv kom tsis pub ntau tshaj 10 RPM; ib zaug ruaj khov, xauv hauv qhov ntsuas.
Cov Ntsiab Cai Kev Tshawb Fawb Tom Qab Kev Sib Tw Ceev
Kev nkag siab txog cov kev pom zoo no yuav tso cai rau koj ua haujlwm cov khoom siv nrog kev paub ntau dua:
Kev sib hloov ceev yog inversely proportional rau pub siab; nce qhov kev sib hloov ceev los ntawm 10% yuav tsum muaj kev txo qis hauv siab ntawm 5%.
Rau txhua txhua 10℃nce hauv hydraulic roj kub, qhov kev sib hloov ceev yuav ib txwm txo los ntawm 2-3 RPM.
Dual-pamp linkage systems pab kom tsis txhob muaj kev sib tw (infinitely variable) ceev tswj, muab peb npaug ntawm qhov yooj yim ntawm cov tsoos mechanical gearboxes.
Nyob rau hauv cov kev tshwm sim ntawm ib tug cia li xyaum me ntsis jamming, lub electronics tiv thaiv system yuav cia li txo qhov kev sib hloov ceev mus rau ib tug zoo theem nyob rau hauv 0.3 vib nas this.
