Replaceable wearing surface for a sealing arrangement

摘要

The replaceable wearing surface is for a sealing arrangement on drum end walls on a press drum that de-waters fiber suspensions radially into the drum through the shell of the drum. The wearing surface of the sealing arrangement has a wear ring and holder members. The wear ring is, on a side that faces into the drum from the drum end-wall, provided with locking members. The locking members are arranged parallel to the drum axis and are preferably in the form of knob-shaped locking members. The arms of the holder members are designed to engage the locking members. The holder members are fastened to the drum end wall by suitable fixing members.
