New PDF release: Forsthoffer's Rotating Equipment Handbooks, Vol. 2: Pumps

Over fresh years there were great adjustments in these industries that are all in favour of the layout, buy and use of specific goal (ie serious, high-revenue) rotating gear. Key group of workers were the sufferers of early retirement or have moved to different industries: contractors and end-users have decreased their technical employees and for that reason need to examine complicated fabric 'from scratch'.

Example text

7. 7 Effects of pump oversizing Pumps are designed to operate at minimum radial thrust loads at best efficiency point. Low flow operation results in high radial loads which can cause premature bearing failures unless bearings are selected to accept these higher loads in anticipation of operation at low flows. Pressure surges and flashing of the liquid can also occur at low flows. This can cause loading and unloading of the mechanical seal faces which can result in a seal failure. Depending on the fluid being pumped, low flow operation can result in a high temperature rise through the pump because the amount of energy absorbed by the liquid is low compared to that absorbed by friction losses.

G. G. G. G. G. on performance Also, once the performance of a pump is known, the discharge pressure and horsepower will be influenced by changes in specific gravity of the liquid being pumped. 16 presents a summary of centrifugal pump characteristics. G. 16 Pump characteristics kinetic (centrifugal) The effect of system resistance on performance Now that centrifugal pump performance characteristics have been defined, we will consider the requirements of the system in which the pump is installed.

By examining the system in Figure 4 . 1 , it can be seen that any system relative to the pump is comprised of two parts; the suction system and the discharge system. Therefore, the objective of the pump is to move liquid from the suction system process pressure level to the final discharge pressure level. Liquid flows from the suction vessel to the pump as a result of a reduction in pressure resulting from friction loss in this part of the system (above vapor pressure to present flashing). ) from the terminal point back to the pump flange.
