低转速内曲线大力矩液马达六十年代在国外就已应用在采煤机上。几个先进国家以大力矩液马达作为牵引的采煤机仍然占主导地位,如英国的AM10/12、AM—16采煤机,法国的THV—16、DTS—300、STBVS—400采煤机都在使用。76年引进的AM10/12薄煤层采煤机液马达在双鸭山七星矿使用近一年来,从未拆检过。阜新清河门矿使用5个月,共采煤13万吨,平均月产26000吨。我国65年以来生产的MLS_2、MLX—50、MLH_2等采煤机的液马达与AM10/12液压马达结构相似,MLX—50型采煤机到
Low-speed curve of torque hydraulic motor in the sixties abroad has been used in shearer. Some advanced countries still dominate with shearer motors as traction shearers, such as UK AM10 / 12, AM-16 shearer, France THV-16, DTS-300, STBVS-400 shearer Are in use. The 76-year-old AM10 / 12 thin seam coal mining hydraulic motor was unopened in Shuangyashan Qixing Mine for nearly a year. Fuxin Qinghe Mine use 5 months, a total of 130,000 tons of coal, the average monthly output of 26,000 tons. The hydraulic motors of MLS_2, MLX-50, MLH_2 and other shearers produced in our country for 65 years are similar in structure to the AM10 / 12 hydraulic motors. The MLX-50 shearer arrives
