For long rotors a resonance exists, as Fig. 5.12 shows for a rotor with I j = 1.1 I p, 2I P and 57p. From equations (5.26) the maximum of Vt is close to v — 1, that is at Q — on, where from equations (5.10) and (5-21), 2 = J?4. The corresponding amplification

1997-6-1The non-linear effects in journal bearings can dominate the rotordynamic behaviour of a vertical machine. This paper describes both linear and non-linear analyses of a twelve stage multiphase pump. For the linear case, the radial tilting-pad journal bearings are characterised by stiffness and damping coefficients.

2014-9-17Vertical stiffness was measured for a 260/80R20 radial ply agricultural drive tire using five methods; load- deflection, non-rolling vertical free vibration, non-rolling equilibrium load-deflection, rolling vertical free vibration, and rolling equilibrium load-deflection. Tests were conducted at three inflation pressures (41, 83, and 124 kPa).
As non-contact seal, labyrinth seal is widely used in rotor system of high speed. However, with the development of turbo-machinery toward high performance and huge capacity, gas excitation vibration within the labyrinth seal becomes the main reason threatening safe operating of machinery sets. Recently three dimensional computational fluid dynamic was applied to
2015-4-10Vertical pump orientation demands overhead space for maintenance especially in the heavier horsepowers, such as 15+ hp; for larger motors you require an overhead rail and hoist. Horizontals are easier to manhandle and lift, shift around. why do we use horizontal or vertical centrifugal pumps 4.
2021-2-22Vertical crushers are one of the most prominent forms of gripping weapons found in Robot Wars.. The pioneer of this type of weapon, and by far the most successful, was double World Champion and UK Series 5 champion Razer.The weapon is so closely identified with its pioneer that most vertical crushers are instantly compared with Razer; Jonathan Pearce made

2016-1-10The use of long shaft vertical pumps is common practice in the nuclear waste processing industry. Unfortunately, when such pumps employ plain cylindrical journal bearings, they tend to suffer from rotordynamic instability problems due to the inherent lightly-loaded condition that the vertical orientation places on the bearings.
