3.15 Operating Checks
WARNING
In the interest of operator safety the unit must not be operated above the nameplate
conditions. Such operations could result in unit failure causing injury to operating
personnel. Consult instruction book for correct operation and maintenance of the pump
and its supporting components.
CAUTION
Operation at low flows results in pump horsepower heating the liquid. A bypass may be
required to prevent vaporization and subsequent pump damage. Refer to local
FLOWSERVE branch to determine if a bypass is required. Mechanical damage may result
from continuous operation at flows less than the specified minimum continuous stable
flow.
Immediately after start up, and frequently during running check the following:
1.
Check suction and discharge pressure gauges.
2.
Check pressure gauges on each side of suction strainer.
3.
Check for excessive leakage at seal areas.
4.
Check for unusual noises.
5.
Check oil level in bearing housing. (Refer to
Section 4
).
WARNING
Operation of the unit without correct lubrication can result in overheating of the bearings,
bearing failures, pump seizures and actual breakup of the equipment exposing operating
personnel to physical injury.
6.
Check for adequate flow of cooling liquids.
7.
After unit (Particular to services 130°F (55°C) above ambient) has been operated a sufficient
length of time to reach normal operating temperature and condition, the unit is to be shut
down and a "HOT" coupling alignment check must be made (Refer to
Section 2.6
).
3.16 Normal Start Up
The starting procedure to be followed for normal start up is the same as that for initial starting with
the exception that Step 8 "CHECK ROTATION" does not have to be repeated as long as driver
systems have not been changed since last pump operation.
