弹性金属塑料瓦(简称弹塑瓦)用于水轮发电机推力轴承已获得了良好的效果,由于技术上的原因尚未推广到向心轴承中。由企业、学校、研究所联合研制并经电站实际运行,实现了水轮发电机组的全弹塑瓦(指其推力瓦和各导轴瓦均为弹塑瓦)运行,取得突破性进展。全弹塑瓦运行具有瓦温低,可提高机组效率,取消高压油顶起,可在低速下运转等一系列优点。可广泛用于立式和卧式水轮发电机组上。
Flexible metal plastic tile (referred to as elastic plastic tile) for hydroelectric generator thrust bearing has obtained good results, due to technical reasons have not been extended to the radial bearings. By the joint development of enterprises, schools, research institutes and the actual operation of the power station, the full-scale plastic tile (that is, the thrust tile and the guide bush are elastic plastic tile) of the hydro-generator set achieved the breakthrough progress. The whole run of plastic tile with low tile temperature can improve unit efficiency, cancel the top of high-pressure oil can be run at low speed and a series of advantages. Can be widely used in vertical and horizontal turbine generator set.
