7BZ-4.5 / 16 coal injection pump market for mining coal injection pump 7BZ mine in Shanxi coal injection pump 7BZ-75/16 coal injection pump 7BZ-4.5 / 16 coal injection pump for mining coal injection pump 7BZ-6.3 / 16 coal injection Pump coal injection pump BZ coal injection pump 7BZ-75/16 coal injection pump 7BG-75/160 coal injection pump 7BZ-4.5 / 160 coal injection pump Product details: 7BZ-75/16 coal injection pump Products 7BZ-75/16 coal injection pump swash plate axial piston pump high pressure. Novel structure, compact, lightweight, high efficiency and easy maintenance. Use the pump to the water in front of coal seams, can effectively expel gas, to avoid stirring up dust, thereby improving the efficiency of coal mining, to protect the health of workers, coal injection process is ideal for special equipment. In addition, the pump can also be used for each mining machinery spray dust and water-cooled motor pumping equipment, can also be used for cleaning all types of machinery and equipment used in pumps. 7BZ-75/16 coal injection pump on the illegal coal mine construction project formalities way, divided into four, by the company to choose. (1) shut down. (2) investigation. 7BZ-75/16 coal injection pump by the discipline, prosecution, coal supervisor, safety supervision, land and other agencies to investigate, investigate after completing the formalities. (3) the elimination of backward production capacity hook. According to the law, the different degrees violations, linked to different proportions. Law, the greater the degree of violation, 7BZ-75/16 coal injection pump bear the greater responsibility; a large proportion of the hook in the region, 7BZ-75/16 coal injection pump outside the region linked to a small percentage. (4) specify the merger. 7BZ-75/16 coal injection pump technical parameters Model: 7BZ-75/16 rated discharge pressure / MPa: 16 rated flow / (L / min): 75 volume coefficient / ℅ ≥90 pump efficiency / ℅: ≥75 Note plug number / root: 7 Note plug diameter / mm: 25 Note piston stroke / mm: 25.1 Lubrication: bath cooling method: water jacket cooling motor power / kW: 30 motor rated speed / (r / min): 980 Dimensions / mm: 1650 × 440 × 875 Total weight / kg: 868 JSD-HH Gast Jining Mining Equipment Co., Ltd.
