7.5KW rock drill, KHYD155 exploring water drill rock drill to buy durable Octagon Mining Machinery, welcome new and old customers to negotiate! Rock drill consists of motor, gear box and runway bodies, motors and gearboxes fused called the host, through the sprocket, chain work on the runway. Three-phase AC motor and fan-cooled squirrel-cage induction motor. There are three gearbox output shaft (see Figure transmission), a driven rotary drill pipe, the other is symmetrical two worm shaft, head left through a single-sided friction clutch worm gear systems and the host on the runway Slow Forward, through Double left-sided friction clutch worm gear system and the host on the runway quickly returned. The use of methods and precautions: 1, according to applications and determine the location of drilling rigs (homemade) erection position. 2, the first chain attached to the host, and then be mounted on the runway, both ends of the chain a good connection with the runway, and adjust the chain lever, so that the tension of the chain to get some, and then fixed to the drill rack runway. 3, before drilling the hand rotation to the neutral position, no-load running five minutes, when the motor is good insulation, rock drill no abnormal sound, and the direction of spindle rotation direction of the arrow on the gear, and then mounted on the drill bit and drill pipe connected to water. 4, in the hole when the handwheel slowly rotating direction of the arrow gently connected to the clutch, when the rock drill bit body all the week after and then forced to tighten the clutch, but the force can not be too fierce. Drill down to the desired depth, they should quickly reverse the handwheel stops. Press the arrow to tighten the clutch reverse, the host quickly returned, until the drill completely exit orifice again when stop drilling, or easily damaged bits and parts, then rotate the hand to the neutral position. 5, in the drilling process, if the pipe is bent or jamming occurs, immediately withdraw drill, check: whether the blunt drill or disintegrating tablets, if you are experiencing a hard line faults or check the motor terminal voltage is the rated voltage If less than the rating, you must regulator to ratings. 6, the rock drill hole, the water flow 5-8L/min, pressure is 0.3-0.5Mpa. 7, is strictly prohibited dry hole, (except when using the spiral blade drill), strict implementation of the first water, after drilling, the first stop after drilling without water approach. Got to pay attention to the water supply situation, the case of a sudden without water, you must immediately stop drilling, the drill hole bottom left promptly to prevent clogging and sticking drill accident. 8, junction box components, terminals galvanized washers, not substitute with a large diameter to ensure creepage distances and clearances. 9, rock drill if unusual sounds, you should immediately check repairs. Gear box oil change should be regularly cleaned and, if necessary, the motor periodically drying.
