Pump Rebuilding Essay, Research Paper

Today most of our electric power is produced by Nuclear Power Plants.

Nuclear reactors must be constantly cooled in order to maintain a level of

safety. There are two types of pumps used for cooling the reactor, the

centrifical pump, and the circulating pump. The cooling water pump is a

critical part in a nuclear plant and must be rebuilt continuously to avoid a

reactor melt down. Here are some simple instructions that, if followed,

will make your rebuild job safe, reliable and quick.

First, lock out the electrical breaker that supplies power to the pump.

This will prevent someone from accidentally starting the pump while you

are working on it, thus eliminating a dangerous accident.

Second, close the suction line and the discharge line to the pump, then

open the drain. Opening the drain will relieve any internal pressure in the

pump.

Third, dismantle the pump housing. Most pumps that are built in the

United States have casing?s that are bolted together with 9/16 bolts.

Using a ratchet will save you time.

Fourth, remove the rubber seals from the suction and discharge side of

the pump housing and replace.
