使用以下步骤装配阻风门:

  1. 将阻风板 (9) 装配到轴 (8) 。 宽松地安装螺栓 (10) 。

  1. 安装止推垫圈 (2) 并拧紧螺栓 (5) 。

  1. 为确保螺栓 (10) 正确地固定在轴 (8) 上,完全关闭阻风板 (9) 并拧紧螺栓 (10) 。

  1. 确保阻风板 (9) 完全关闭。 松开锁紧螺母 (3) 并转动调整螺栓 (1) ,直到螺栓紧挨挡板 (6) 。 将螺栓再拧紧 1/4 圈(90 度),然后拧紧锁紧螺母。

  1. 装配执行器,进口 (21) 向上,出口 (22) 向下。 以规定的扭矩拧紧螺母 (18) 。

  1. 4C-4030 螺纹锁固胶 涂抹在 U 型夹 (16) 的螺纹上。

  1. 装配连杆 (15) 。 让连杆两端咬合同等长度的螺纹,直到杆端中心孔之间的距离大致达到规定长度。

  1. 装配连杆 (19) 。 让连杆两端咬合同等长度的螺纹,直到杆端中心孔之间的距离大致达到规定长度。

  1. 最终调整连杆时,应确保当阻风板完全打开时,执行器不会试图迫使挡板 (6) 强行移过板 (4) 。

    1. 完全伸展执行器。 确保阻风板完全打开,挡板 (6) 接触板 (4) 。

    1. 然后缩短连杆 (15) 的长度 1/2 圈(180 度)。

      这可使挡板 (6) 与板 (4) 之间存有间隙。

    1. 确保阻风板能够完全关闭。 以规定的扭矩拧紧螺母 (14) 和螺母 (17) 。
