5.3.7 OIL COOLER
The supply line to the cooler can be connected to either hole. The fluid flowing through the heat exchanger
should be sufficient to keep the oil temperature to the optimum operating range of 150-180 °F (65-80 °C).
This temperature will insure proper lubrication of the bearings and seals. 1.5 to 2 GPM (5 to 7.5 L/min) of
60° F (15° C) water is generally sufficient. Actual water usage will depend on the booster operating condition.
WARNING
If the unit is to be located outside or in a building where ambient temperatures
can fall below freezing, then care must be taken to ensure the water or
liquid used for cooling does not freeze and damage the booster. Oil cooler
must be drained of liquid during downtime unless a re-circulating unit using
a glycol mixture has been installed.
5.4 PIPING CONNECTIONS
WARNING
Pipe loading on the booster should be negligible as pipe loading can cause
distortion of the booster. Use proper supports and pipe hangers to assure
that there is no loading.
NOTE
Remove the protective covers from the inlet and outlet ports and inspect for
dirt and foreign material.
Manifolding should be no smaller than the pump connections in order to minimize restrictions to gas flow.
Accurately align the mating flanges to the inlet and discharge manifolding to prevent distortion of the booster
housing. Temporarily fit a fine wire mesh filter at the suction port if solid particles are likely to be entrained
into the air stream and remove the filter when particles no longer appear. This is especially desirable on
new installations and when manifolds have been welded. The manifolding to and from the booster should
be fitted with flexible connections to isolate vibrations, absorb expansion and contraction due to thermal
change, and to absorb misalignment differences. If the booster is to be water cooled, connect a clean
supply to the ¼” NPT connection on the seal adapter housing adjacent to the drive shaft. The drain line will
be connected on the bottom of the non-drive end reservoir, see Figure 4 for connection locations. Care
should be taken to not over tighten or loosen the bushing for the cooling coil connection. The bushing
should be held in place as additional fitting and plumbing is performed.
HAZARDS ASSOCIATED WITH HAZARDOUS PROCESS FLUIDS
DANGER
It shall be the responsibility of the installer to ensure that piping is adequate,
sealing between pipe joints is adequate for the process fluids and proper
process and pressure protection devices are in place. It is also the
responsibility of the installer to assure that process gasses are not vented
in a manner that would be hazardous.
Refer to the manufacturer of the process media to assure that proper safety
precautions are in place.
5.4.1 BLOCKAGE OR RESTRICTION
WARNING
Damage to the booster could occur if there is blockage in the inlet or outlet
ports or piping. Care should be taken when installing the booster to assure
that there are no foreign objects or restrictions in the ports or piping.
