Test Running

1. Verify that the power is locked out. Inspect the
belt tension (Figure B next page), rotate the
pump and listen for any sound indicating worn
bearings or misaligned impellers. Check that
the inlet and outlet are properly connected.
Also check that the vacuum relief valve is con-
nected.
2. Mount the covering panels. Check that no per-
sons can be hurt if the pump starts and that all
outlets are closed.
3. Connect a manometer for negative pressure
calibrated to min. -50 kPa to the suction side
as close to the pump as possible.
4. Power up the pump and listen carefully for the
following sounds; A high pitch whine is nor-
Service
The pump should be inspected at least twice a year
and lubricated according to the lubrication intervals
at the bottom of this page.
1. Start the pump and listen for abnormal sounds.
When all outlets are closed a weak hissing
sound should be heard from the vacuum relief
valve.
2. Shut off the pump and lock out the electrical
service.
3. Remove the protective panels from the pump.
4. Rotate the pump manually and listen for any
sounds indicating a worn bearing or misligned
impellers.
5. Check the condition and tension of the drive
belts. The drive belts are matched, therefore
new and old belts should never be used to-
gether. Always change the whole set. (A).
Changing the belts
- Lift the motor mounting plate with nut (1).
- Change belts.
- Tighten the belts with nut (2) and adjust to the
tension illustrated (B).
6. Check that the axles, pump and motor are paral-
lel and the pulleys are true. The belts should not
run on an angle into the pulleys. The inclination
of the pump can be changed with screw (3), fi g
C.
mal sound from the impeller blades. As pump
draws cooling air from the vacuum relief valve
a weak hissing should be heard.
5. Measure the pressure. Compare with the di-
mension point. The pressure can be adjusted
by adjustment of the vacuum relief valve. See
Adjusting the vacuum relief valve.
6. Check the function and tightness of the con-
nected exhaust system.
7. Open the number of outlets the system is di-
mensioned for. The vacuum relief valve should
now be totally closed.
8. It is normal that the pump becomes hot during
operation.
7. The bearings of the turbopump should be
lubricated with Dustcontrol bearing grease for
turbopumps, Part No. 9928.
Lubrication
- The front bearing should be lubricated using
the grease nipple (4), fi g (C). Press grease in
until it comes out along the axle.
- The back bearing should be lubricated by
TPR 40, 15 kW - 17
removing the fi nned
bearing cover plate (5)
and checking the con-
dition of the grease. Fill
the cavity 2/3 full with
new grease.
- Exchange the O-ring,
Part No. 4789 and re-
place the bearing cover
plate.
