Maintenance safety centrifuges

Batch centrifuges require frequent cleeming, modifications to their setup, and preventive maintenance. Safety and effectiveness in these procedures require sufficient space with convenient access and easy egress. 

The removal of dust particles, typically 1 to 1,000 microns in diameter, from gas streams (also called gas cleaning) is accomplished on an industrial scale by four main types of equipment (1) bag filters, (2) cyclones using centrifugal force, (3) electrostatic precipitators, and (4) venturi scrubbers using washing with a liquid. Reasons for dust collection include air-pollution control, elimination of safety and health hazards, recovery of a valuable product, improvement in the quality of other products, and reduction of equipment maintenance. Typical ranges of particle size that can be efficiently removed by each of the four methods are as follows ... 

This section highlights additional features to consider in the design of a centrifugal or reciprocating com-Messor layout. There are many ways to develop a ompressor layout, but certain aspects of these marines dictate how best to approach a design that opti- nizes operation, maintenance, and safety while adher-ng to economic requirements. 

Lor this case, the maintenance of the centrifugal pump is better in the sense that people make no omissions in the tasks that have to be performed in the maintenance and repair of the pump. In this case, it means that the probability of skipping a safety-sensitive maintenance activity is effectively reduced to zero. The effect on the overall LoC frequency of the centrifugal pump clear the mean has lowered by 17% from 0.0051 + 0.00452 to 0.0042 0.00452. However, the contribution on the LoC s of the whole unit is negligible since just one pump is installed in this case. 

Figure 6.1 Ultracentrifuge. Because they are so expensive, centrifuges are frequently shared by more than one research group. Safety and maintenance procedures may therefore be less rigorous than if one lab had sole responsibility for their use.
