Maintenance & Reliability

Case 4: The wrong bearing in the right place

Consulting Engineer: Sofronas, A.

Calculate B10 life to ensure reliable operation

HP Reliability: Improve turboexpander shaft seals and bearings

Hydrocarbon Processing Staff: Bloch, Heinz P.

Virtually all cryogenic turboexpander seals are either close-fitting labyrinth or noncontacting (dry) gas types. Conventional mechanical seals are not generally used; high velocities prohibit use of c..

Consider precast polymer concrete pump foundations

Structural Perservation Systems: Welch, L.

Features include faster installation, improved corrosion resistance and lower vibration levels

HP Reliability: Conclusions drawn from bearing life equations

Hydrocarbon Processing Staff: Bloch, Heinz P.

Fig. 1 shows an example of the influence of contamination on bearing life in general terms. A "real life example" best illustrates the various aspects of bearing life calculations. It s..

Case 3: Shaft galling in a bushing

Consulting Engineer: Sofronas, A.

When troubleshooting, the cause may not be as obvious as it first appears

Control valves for critical applications

Samson AG: Kiesbauer, J.

Know the causes of cavitation and flashing and how to prevent them

HP Reliability: Expander power absorption methods

Hydrocarbon Processing Staff: Bloch, Heinz P.

Turboexpanders frequently used in refrigeration processes develop power, but recovery of this power has often been of secondary importance. A number of power absorption methods are dire..

HAZROP: an approach to combining HAZOP and RCM

P.E., Rohm and Hass Co: Post, R. L.

A single merged activity provides resource savings

HP Reliability: Oil feed rates for reciprocating compressors

Hydrocarbon Processing Staff: Bloch, Heinz P.

In the lubrication of double-acting compressor cylinders, one of the most important factors is the oil feed rate. Likelihood of over-lubrication is greater than that of supplying too li..

Using wireless technology and the Internet for predictive maintenance

Recent developments in sensors and computational power enable more machines to be monitored inexpensively
