BASEPLATE AND SUPPORTS
**************************************************************************
NOTE: If Alternate 2 or 3 of paragraph [CRITICAL
SPEEDS] [DYNAMIC ANALYSIS] is part of the contract,
the results of the dynamic analysis are included as
a load.
Seismic design criteria are provided in TI 809-04
(http://www.hnd.usace.army.mil/techinfo/index.htm).
**************************************************************************
The baseplate shall be proportioned to support the entire pump assembly,
the [reduction gear][motor] and the loads (including the results of the
dynamic analysis) to which it may be subjected during operation. It shall
be supported and anchored as shown on the drawings. Lifting lugs or eye
bolts, special slings, strongbacks, or other devices necessary to handle
the pump during loading, unloading, erection, installation, and subsequent
disassembly and assembly shall be furnished. A sole plate [as shown on the
drawings] shall be provided under the baseplate. The sole plate shall be
installed, leveled and grouted in accordance with API RP 686, Chapter 5 -
Mounting Plate Grouting. Jacking bolts shall be provided for leveling the
baseplate assembly. An anchor bolt layout shall be provided to aid in
placement of anchor bolts. All leveling jacking bolts shall be backed off
after grouting so that they do not support any of the load. The pedestal
supporting the [motor][right-angle reduction gear] shall contain a 25 mm
1-inch lip to contain water leakage from the shaft packing. A threaded
drain to the sump shall be provided.[ Seismic requirements shall be in
accordance with Sections 13080 SEISMIC PROTECTION FOR MISCELLANEOUS
EQUIPMENT and 15070A SEISMIC PROTECTION FOR MECHANICAL EQUIPMENT.]
2.7
FREEZE PROTECTION
All parts of the pump shall have drain holes to eliminate trapped water
that could freeze. These drain provisions shall be self-draining without
any requirement to enter the sump.
2.8
FACTORY ASSEMBLY
The pump shall be assembled at the manufacturer's plant[ in a vertical
position] to assure proper fitting and alignment of all parts. Tolerances
shall not exceed those specified or shown on the the Contractor's
manufacturing drawings. Rotating elements shall be checked for binding.
The suction bell, impeller housing, diffuser, and the discharge elbow shall
be properly match marked and have their centerlines clearly marked on the
outside of all flanges to facilitate erection and alignment in the field.
The Contractor shall notify the Contracting Officer sufficiently in advance
to permit a representative of the Contracting Officer to inspect and
witness the pump assembly. All parts disassembled for shipment shall be
matchmarked.
