leveling and installation Flashcards
primary equipment means
first equipment set in place
main support machine rests is
foundation
point of permant character established by the surveyor used as a reference point
bench mark
electric motors combustion engines known as
prime movers
it is critical to inspect equipment for damage on delivery
True
care of equipment prior to installation
filling bearing housing with lubricant, remove foreign materials, rotate shafts, all of the above
most important consideration lifting equipment is that its balanced?
True
a complete equipment installation
all of the above/ levelling aligment test running installation
prior to installing specified lubricant
remove the flushing oil from equipment
prior to powering up new equipment
install all equipment guards and platforms
record of installation should be kept for each piece of equipment
true
prior to installation of prime mover bearing clearances should be checked
true
mounting method for machinery must
support, absorb vibrator, secure machine/ all the above
equipment that is mounted directly on concrete floors
requires special mounting pads
when ever mounting equipment on structural steel use a
base plate
when using adjustable machinery mount it is important to do
cleaned and greased so it doesnt jam
a unit that prevents machine vibrations
vibration isolator.
vibration isolator may be
absorbent pad or spring mounted
essential foundations of machine
true
machine sole plates installed
for shimming
when using L shaped anchor bolts, the length of the bend should be
4 times the diameter
straight anchor bolts without deformed ends
installed 25 times their diameter
purpose of a pipe of tube anchor bolt
to provide movement in the anchor bolt
boxed anchor bolts designed for access to replace
true
packing waste may be used from the anchor sleeve
true
where anchor bolts need to be installed in exsisting concrete
hole is drilled and mechanical advantage anchors used
anchor that uses two component adhesive is called
chemical adhesive
when positioning and setting anchor bolts ensure that
each anchor bolt is in its location, sits straight in hole, all of the above
in order to ensure anchor bolts in exact location
use a template
it is acceptable to weld anchor bolts to rebar
true
when the floor of foundation exists the method to find anchor bolts
locate anchor bolts on drawing, find sinch points/ all of the above
main reference lines provide
mark from main line
a general rule of thumb when working with refernce lines
keep the lines to a minimum so not many errors
the main purpose of center lines is to show exact machinery measurements
true
center lines are constructed using reference
poiints datums all of the above
refernce points are often established close to or
with a brass plug close to or in existing plate
when installing piano wire for reference line
install reference point because its taut
when using theodolight care must be taken
aligning, checking for error, all of the above
jacking screws are used
for shimming
most common way to raise a machine in aligment
is shims
if a base plate is in an isolated position and level it must be established with an optical tool
use theodolight
construction rotating level takes a plain level to take all elevation measurements
plain extends 360 degrees
many grouts contain many respritory system
consult msds sheet
on a 12 inch master precision level requires .3000 in shim on a bed 4 ft long
.3 x 4 = .012 thou
