DEVICE FOR A PAPER MACHINE FOR CONVEYING LIQUID FROM A FIRST LEVEL TO A SECOND, HIGHER LEVEL

摘要

The mechanism in a papermaking machine to raise fluid from a chamber at one level, through a channel (32) to a zone (20) at a higher level, to prevent unstable flow ratios and pulsation, uses a difference in gas pressure (p1, p2). A throttle point (28) controls the flow through the channel (32). The throttle point (28) is controlled to throttle the fluid flow by an increase in the gas flow through the channel (32).
