Pumps, centrifugal description

The final element of the equipment description is the equipment boundary figure. A boundary figure is included with each data cell to define the components and limits of the equipment associated with that cell. For example, the data cell boundary figure (Data cell 3.3.7.2.1.1) in Figure 3.2 shows that the centrifugal pump, seal system, motor, motor control unit, lube oil system, coupling, and transmission are all components of the equipment in the data cell. The equipment boundary is inherently reflected in the taxonomy number. [Pg.17]

Crystallisation theory is covered in Volume 2, Chapter 15, and in several other texts Mullin (1992), Van Hook (1961), Nyvlt (1971) and Janie and Grootscholten (1984). Descriptions and illustrations of the many types of commercial crystalliser used can be found in these texts and in various handbooks Perry and Green (1984), Schweitzer (1988). Procedures for the scale-up and design of crystallisers are given by Mersham (1984), (1988), (1995). Bamford (1965) includes details of the ancillary equipment required vacuum pumps, circulation pumps, valves, filters, centrifuges and dryers. [Pg.435]

Several types of compressor have characteristics intermediate between those of PD compressors and centrifugal or axial-flow compressors. These include the lobe type, sliding vane, and liquid piston. For all these, the discussion of compressor work and compressor efficiency applies just as well as the above-mentioned types. Descriptions of the mechanical arrangements of these can be found in texts on pumps and compressors [2]. [Pg.345]

A pressure filter fed by a punqt other than a positive displacement type provides this kind of filtratian. The most common exanq>le is that of a centrifugal pump feeding a plate and firame pressure filter. Under these circumstances the dehveiy pressure of the punq> increases as the flow rate decreases. Ibe flow decreases as a consequence of increasing total resistance to filtration due to the increase in cake depth. The mathematical description of this process depends on knowledge of the pump characteristic, such as that shown in Figure 2.10. [Pg.50]

A self-flushed pump with a single set of mechanical seal faces can leak the process fluid into the environment. If the process fluid is hydrocarbons, this sort of leakage is no longer permitted by the EPA. The sketch I have shown in Fig. 37.1 does not represent the actual configuration of a double mechanical seal component, but does explain the function of the individual pump internal components (see reference 2 for an excellent description of the actual arrangements of the internals for an overhimg, wet sump, centrifugal pump). [Pg.495]
