Qhov ua haujlwm voltages ntawm ob yog txawv, yog li lub zog ntawm kev sib hloov thaum lub sijhawm ua haujlwm yog txawv, thiab 24v zog muaj zog dua.
Lub tshuab hluav taws xob yog lub tshuab drilling uas siv hluav taws xob ua lub zog hluav taws xob. Nws yog cov khoom siv yooj yim hauv cov cuab yeej hluav taws xob thiab cov cuab yeej hluav taws xob uas xav tau tshaj plaws. Kev tsim khoom lag luam txhua xyoo thiab muag rau 35% ntawm Tuam Tshoj cov cuab yeej hluav taws xob.
Cov ntsiab lus tshwj xeeb ntawm kev ntsuas hluav taws xob yog 4, 6, 8, 10, 13, 16, 19, 23, 32, 38, 49 mm, thiab lwm yam. Cov nuj nqis xa mus rau qhov siab tshaj plaws ntawm txoj laum txoj haujlwm tawm ntawm cov hlau nrog tensile lub zog ntawm 390 N / mm2. Rau cov hlau tsis muaj hlau, plastics thiab lwm yam ntaub ntawv, qhov siab tshaj plaws drilling kab yuav yog 30-50% loj dua li cov qauv qub.
