Preßelement

Pressure element - with collector unit in oil siphon system which is mounted at points least influenced by beam deflections

Abstract

The pressure element (1) comprises a stationary beam (2), a rotating hollow roll, at least one hydraulic-action support element which is supported against the beam and can be pressed - in the direction of gravity - against the inner roll surface, and an oil siphon system. The oil siphon system includes a central collector unit (16) which is located between the outer siphon tubes (14a-14c) and the inner siphon tube (13). The syphon system is mounted at points within the beam and regions (20,21) which are least influenced by deflection. USE/ADVANTAGE - In paper manufacture, in materials smoothing installations etc. A more effective siphoning system ensures oil removal from the sump under all operating conditions of the pressure element.
