转浆式水轮机转轮体的铜瓦与叶片轴的配合一般地选用二级精度第二种动配合D/db(紧动配合)。铜瓦精车后压入转子体,铜瓦的内孔要收缩,其收缩量一般地是铜瓦的过盈量的(1.05～1.15)倍。在生产
Pulp turbine wheel body copper tile and blade shaft with the general use of the second level of precision with the second dynamic with D / db (tight-fitting). After the copper wrought iron car into the rotor body, the copper hole to shrink the hole, the shrinkage is generally the amount of interference copper (1.05 ~ 1.15) times. In production
