M 3355 Final - Maintenance &Turnarounds with complete
verified solutions(graded A+)
Pumps, compressors, Fans, Motors, blowers, turbines, conveyors,
feeders. - answer Rotary equipment
has a driver, connector and the driven equipment - answer rotary
equipment
rotary equipment = ____ rotation - answer shaft
motors and turbines = ___ of rotary equipment - answer drivers
pumps, compressors and fans are what kind of equipment?
____ (rotary) - answer driven
couplings, belts or chains are the _____ of rotary/shaft rotation
equipment. - answer connectors
fixed couplings can be __ or ___ - answer rigid or flexible
small (drive) gears = ____ - answer speed
Large (drive) gears = greater ____ - answer torque
3 principals of electric motor rotary equipment: - answer a. Current
creates mag field
,b. opposite poles attract, likes repel
c. curent direction determines mag poles
Elec Motors consist of a stationary magnet called a ______ and a
moving conductor called a *rotor* - answer stator
these pumps move fluids/liquids by stroke or rotation. 2 types are:
- Rotary
- Reciprocating - answer positive displacement pumps
displacing fluids by means of a piston or plunger - answer
reciprocating (positive displacement)
Pumps, Compressors, Fans - answer Rotary Equipment
two types of pumps: - answer Centrifugal and Positive displacement
Two types of Positive Displacement pumps: - answer - Rotary
- Reciprocating
this pos. displacement pump displaces fluids by means of piston or
plunger - answer Reciprocating pos. disp. pump
2 Main types of Compressors - answer Dynamic and Positive
Displacement
____ ___ accelerate gas and converts kinetic energy to pressure -
answer dynamic compressors
2 types of Dynamic compressors: - answer centrifugal and axial
,Which type of Dynamic Compressor uses a rotating shaft with
blades to push gas over stationary blades (stators) attached to the
casingic energy is released in the form of pressure - answer Axial
___ ___ main types of Compressor that traps the gas and forces it
into a smaller volume - answer Positive Displacement Comp.
2 types of Pos. Displacement compressors - answer Rotary and
Reciprocating
(so the two forms of Positive displacement equipment (both pumps
and comps)) are _____ and __ - answer Rotary and Reciprocating
Pumps do what? - answer move liquids
Compressors ____ ___. - answer transfer gases
_____ ____: converts kinetic energy to mechanical energy and is used
as a driver for pumps, comp., etc. (rotary) - answer Steam Turbine
Horizontal Cylindrical Vessels are also called " ___ " - answer vessels
separates solid particles from a fluid by passage through a porous
medium
• Ex. Cartridge, medium (sand, carbon elements, etc) - answer
filters
- hot fluid transfers energy in the form of heat to a cooler fluid
without physical contact between the two fluids
• Can also do the opposite (provide cooling to a process)
, • Components - shell, tube bundle, water box / head - answer Heat
Exchangers
(stationary)
___ ___:
• used to remove heat from water
• Heat is transferred to cooler air
• Major portion of heat is stripped from the water by evaporation -
answer cooling towers
___ or __ ___s:
used to produce steam
• Water is heated to produce steam - answer boilers or steam
generators
used to heat up raw materials so products are produced (ie.
Gasoline, oil, kerosene, plastic, rubber)
• Basic components - metal shell surrounding a firebox (lined with
refractory), convection section, and a stack - answer furnaces or
fired heaters
(stationary)
vessel used to convert raw materials into useful products through
chemical reactions
• Raw materials are combined with a catalyst, gases, pressure, and
heat to produce a transformation - answer reactors
(stationary)
