instructions, and schematic diagrams. Rigidly affix identification plates
or tags to the equipment or devices without impairing functions or, when
this is not possible, attach using a non-ferrous wire or chain. In
addition to identification plate or tag, each major component of equipment
shall have a nameplate listing manufacturer's name, model number, and when
applicable, electrical rating and other information required by pertinent
standards or codes.
2.18
TOOLS AND TESTING EQUIPMENT
Provide special tools and wrenches required for installation, maintenance,
and operation of equipment. Testing equipment to be provided shall include
necessary equipment to perform routine tests:
a.
On lubricating oil for acidity (pH-potentiometer), viscosity
(saybolt test), and dirt (gravimetric).
b.
On softened water for hardness (soap test or colorimetric test),
and boiler blowdown water for pH (colorimetric) and conductivity
(potentiometer).
c.
For water (distillation) and sediment (gravimetric) in fuel oil.
2.19
WELDING MATERIALS
Comply with ASME BPVC SEC II-C. Welding equipment, electrodes, welding
wire, and fluxes shall be capable of producing satisfactory welds when used
by a qualified welder or welding operator using qualified welding
procedures.
2.20
MOTORS AND DRIVES
Alternating current electric motors shall meet requirements of NEMA MG 1.
Motors shall be designed for continuous operation at rated load under usual
service conditions as defined by NEMA. Unless specifically noted
otherwise, motors less than 3/8 kW 1/2 hp shall be 115 volt, 60 Hz, single
phase, capacitor-start, or permanent split capacitor, with Class B
insulation for 40 degrees C 104 degrees F ambient. Unless specifically
noted otherwise, motors 3/8 kW 1/2 hp and larger shall be 460 volt, 60 Hz,
three phase, Design B, squirrel cage induction with a minimum insulation of
Class F for 40 degrees C 104 degrees F ambient. Size motors to meet power
requirements of driven unit at design conditions, including drive and
coupling losses which are incurred, without loading motor beyond its
nameplate horsepower rating. Minimum service factor for open drip-proof
motors shall be 1.15 and for totally enclosed, fan cooled motors 1.0.
Motor shall be quiet operating. Bearings shall be heavy duty, grease
lubricated, anti-friction, single shielded, regreasable type and shall have
approved lubricating fittings extended to an easily accessible location for
field servicing. Provide sole plates for motors installed on concrete
pads. Motor shall have copper windings.
2.20.1
Motors
Motors used to drive equipment specified under "Coal Handling Equipment"
shall be designed to operate in Class II, Division II, Group F atmosphere.
