Rotary valve rotor contact detection systems

method is inexpensive and good for conducting electrical current but can be sensitive to heat and contamination, which can cause resistance between the rotor shaft and the brush, interfering with the system’s operation. System controls The control module for a rotor contact detection system is, in essence, an ohmmeter with alarm outputs and other adjustable settings. With limited exceptions

Rotary straighteners for tube and pipe The FABRICATOR

For a low-carbon steel pipe with a 0.541-in. OD, 0.118-in. wall thickness, a straightness variance of 0.048 in. per foot, and an ovality variance of 0.0002 in., a six-roll machine can improve the straightness to 0.0018 in. per foot and ovality to 0.0000 in. However, a 10-roll machine can improve the straightness further to 0.0006 in. (see

Wire Straightening Theory & Practice

The rotary method is by far the best way to straighten wire but is very expensive to implement, is slow, and can leave marks on the wire called “barber poling” which appear spiral in nature if not set up correctly. In the case of the roll straightener the wire is maneuvered or forced to traverse a course around roll bearings like a skier running a slalom course. The wire is bent past its
