典型的焊接隔板由隔板体、外环、静叶片(导叶)和内、外围带组成。为减小损失,较低压力级的隔板围带呈锥形。 传统的焊接隔板制作工艺过程为:内、外围带冲型孔,成型→叶栅装配焊接→叶栅除应力退火→外环,叶栅和隔板体的装配焊接→焊接隔板除应力退火→转机加工。 A typical welding separator by the separator body, the outer ring, vane (guide vane) and the inner and outer bands. In order to reduce the loss, the diaphragm band of the lower pressure level is tapered. The traditional welding diaphragm manufacturing process is as follows: the inner and outer peripherals with punching holes, molding → cascade assembly welding → cascade annealing in addition to stress → outer ring, cascade and separator body assembly welding → welding separator in addition to stress annealing → Transfer processing.
