Mounting
Proper mounting of QT & PLT series compressor units is crucial to the safe
operation and longevity of the equipment. The installation requires a flat and
level concrete floor or pad
(for mobile units see
Mounting
Mobile Units
)
. Satisfactory results can usually be ob-
tained by mounting the compressor unit on vibration
isolating pads available from your local Quincy distribu-
tor.
All vertical tank units must be anchored!
Refer to
Fig. 3-7, Isolator Installation for Unanchored or
Anchored Receiver
.
State or local codes may mandate that the compressor
be bolted to the floor. In this case the unit must be leveled
and bolted making absolutely certain the feet are not
stressed in any manner.
Leave the flange nut loose &
lock it with a back-up nut!
Uneven feet drawn tightly
to the concrete pad will cause severe vibrations resulting
in cracked welds or fatigue failure. The customer is
responsible for providing a suitable foundation & isolator
mounting where necessary.
Mounting Mobile Units
Gas engine driven compressors mounted to truck beds should be fastened in
such a way so as not to create any stress to the air receiver tank. Truck beds,
characteristically, have a tendency to flex and could cause damage to the
receiver tank if the tank is fastened directly to the truck bed. It is the user’s
responsibility to provide an adequate means of fastening the unit in these
applications.
Do not operate this compressor more than 15° off level or move it
while it is operating.
System components
Efficiency and safety are the primary concerns when selecting components for
compressed air systems. Products of inferior quality can not only hinder
performance of the unit, but could cause system failures that result in bodily
harm or even death. Select only top quality components for your system. Call
your local Quincy distributor for quality parts and professional advice.
Drive Pulleys / Sheaves
Various pulley and sheave combinations are available to obtain the desired air
pressure and delivery rate of your compressor. Consideration must be given to
these combinations to ensure that the motor is not overloaded by operating
above or below the designed speed range.
Whatever combination is employed, the drive pulleys & compressor sheaves
must be properly aligned and drive belt tension set to specifications (refer to
SECTION 5,
Pulley / Sheave Alignment & Belt Tension
). Improper pulley/
sheave alignment and belt tension can cause motor overloading, excessive
vibration, and premature belt and/or bearing failure.
