There are two kinds of wet coal drill coal drill and drill dry coal. With coal drill, wet coal drill coal drill there and dry coal drill. With coal drill. Coal mine for drilling rigs in use handheld coal and soft layer structure with a mine explosion-proof and water device that can be safely used for methane and coal dust explosion hazard of mine. Quality control and advanced design and development are equally important to the quality of economic 宁鑫隆 machinery, depending on the production process. While the rational allocation of resources, the spirit of "meticulous," the quality of ideas, scrupulously according to user requirements and relevant national, industry-standard technical requirements for each channel technology layers of inspection and checks to ensure that every detail from product quality and delivery. ? The main technical parameters Model Weight 15 kg ZM12 coal drill spindle speed 520 r / min spindle torque of 22 Nm Drilling diameter Φ (38 ~ 45) mm Rated Power 1.2 KW Rated voltage 127 V Rated frequency 50HZ Rated current Phase 3N 9A motor efficiency 76% working methods S 2 -30min (half an hour of intermittent work)? ZM12 type coal mine explosion-proof electric drill, applicable to gas (methane) or coal dust in mines dangerous, for medium hard and hard coal and soft rock drilling for eye use handheld rig, the drill has a low temperature, high efficiency, large output, long life and the advantages of the scope and purpose:? ZM series of coal drill for coal mine and surrounding medium is methane, coal dust and other explosive mixture gas environment, in AC 50Hz, voltage 127V power supply network in the face of the mining and tunneling work hard and hard coal drilling purposes. ? ZM12 coal drill by flameproof motor, reducer, switches and other components. For safe operation, drill about manipulation handle, switch handles, hood etc of plastic insulated cable for mine UZ3 × 4 + 1 × 4 with rubber cables, wiring should be a good end of the cable stripping tin After, put the plastic casing, and then wiring, grounding and note the wiring seat marked "⊥", can not take the wrong cut. ? Environmental conditions: ● altitude less than 1000m. ● Operating ambient temperature does not exceed + 40 ℃. ● Underground relative humidity less than 95% (+ 25 ℃ when). ● ambient air containing methane gas and coal dust explosion.
