Pump Rebuilding Essay, Research Paper
Today most of our electric power is produced by Nuclear Power Plants.
Nuclear reactors must be invariably cooled in order to keep a degree of
safety. There are two types of pumps used for chilling the reactor, the
centrifical pump, and the circulating pump. The cooling H2O pump is a
critical portion in a atomic works and must be rebuilt continuously to avoid a
reactor melt down. Here are some simple instructions that, if followed,
will do your rebuild occupation safe, dependable and speedy.
First, lock out the electrical ledgeman that supplies power to the pump.
This will forestall person from by chance get downing the pump while you
are working on it, therefore extinguishing a unsafe accident.
Second, near the suction line and the discharge line to the pump, so
open the drain. Opening the drain will alleviate any internal force per unit area in the
pump.
Third, dismantle the pump lodging. Most pumps that are built in the
United States have casing? s that are bolted together with 9/16 bolts.
Using a rachet will salvage you clip.
Fourth, take the gum elastic seals from the suction and discharge side of
the pump lodging and replace.
Fifth, inspect the bearings for wear or marks of overheating. Over warming
usually causes the bearing to turn blue in colour ; if this is observed the
bearing should be replaced.
Sixth, take the gasket from the pump lodging. Since the pumps are
exposed to high heat a combatant may be needed to take it wholly.
Caution should be used so that the lodging is non gouged. Sandpaper the
lodging and put in new gasket.
Seventh, bolt the lodging back together. Since most cooling H2O pumps
are low force per unit area, torquing is non required.
Eighth, Open suction and discharge valves. Leave the drain line unfastened until
you see a steady watercourse of H2O coming out, so shut the drain. This
will maintain the seals from firing up do to the pump non being primed.
Ninth, unlock the ledgeman and trial run the pump.Be sure that the suction
and discharge force per unit areas are right. If the pump develops the right
force per unit areas, it is working decently.
Tenth, return the pump to service and procure the following pump to be rebuilt.
If these stairss are followed closely, it should let you to reconstruct your
pump rapidly, safely, and expeditiously, therefore lengthening the clip between
rebuilds.
