pumps Flashcards
pump least suitable to delivering fluid at high pressure
single stage
Effective method for controlling flow rate through pump
speed up or slow down pump
Sequence of centrifugal pump shutdown
suction then discharge valve
What can cause excessive vibration on pumps
not enough lubrication, worn bearings, misaligned couplings
Basic pump operation
a pump is a rotary or reciprocating machine where force is applied to a liquid contained. discharge valve then suction valve
Monitoring pump
Visually inspecting levels, taking temperature readings and listening for any changes in sound or loud emissions
Barrier fluids
Needs to be compatible with the process, compatible with the seal materials, good lubricant and heat transfer for seal faces, benign to the surroundings
