what does a pump create high or low presure at the inlet?
low(negative)
if the pump inlet was plugged what would that do to the flow?
Cavitation
what are the types of contamination
Air,Water,Heat, Dirt, Prime Mover
what does shaft alignment mean
pump input shaft to output shatf of prime mover
if the prime mover rpms jump up fast what will this cause in the system
Cavitation
what is the vacuum gauge for
measure inlet recision
what does operating temperature mean and why is it important to bring the machine to that temperature
normal operating temp of veichel and peak of oil viscosity
what type of drains do pumps have
external and internal
what are the main parts of a piston pump
piston, swashplate, piston shoes, barrel
tools for testing pumps
tachometer, temp gauge, vacuum gauge, pump tester, presure gauge
what would low fluid cause to a system
Cavitation and start to rust the tank
can the engine cause flow issues
yes
what would a clogged filter cause in the system
high inlet restrictions
can I overwork the gpm of a pump
yes
how do we test pump
pump tester
when does a pump fail its test
70%
what injury can happen with high pressure leakage
injection wound
