Страница: 83 / 104

CAUTION
Impermissibly high temperature of fluid handled
Damage to the pump!
▷
Prolonged operation against a closed shut-off element is not permitted
(heating up of the fluid).
▷
Observe the temperature limits in the section on operating limits. (
⇨
Section 6.2
Page 25)
While the pump is in operation, observe and check the following:
▪
The pump must run quietly and free from vibrations at all times.
▪
In case of oil lubrication, ensure the oil level is correct.
▪
Check the shaft seal. (
⇨
Section 6.1.4 Page 24)
▪
Check the static seals for leakage.
▪
Check the rolling element bearings for running noises.
Vibrations, noise and an increase in current input occurring during unchanged
operating conditions indicate wear.
▪
Monitor the correct functioning of any auxiliary connections.
▪
During operation the pump set is subjected to vibrations which can loosen
screwed connections. Regularly check the pump set for any loose connections.
▪
Monitor the stand-by pump.
To make sure that the stand-by pumps are ready for operation, start them up
once a week.
▪
Monitor the bearing temperature.
The bearing temperature must not exceed 90 °C (measured on the outside of the
bearing bracket).
CAUTION
Operation outside the permissible bearing temperature
Damage to the pump!
▷
The bearing temperature of the pump (set) must never exceed 90 °C (measured
on the outside of the bearing bracket).
NOTE
After commissioning, increased temperatures may occur at grease-lubricated rolling
element bearings due to the running-in process. The final bearing temperature is
only reached after a certain period of operation (up to 48 hours depending on the
conditions).
7.2.2 Inspection work
DANGER
Excessive temperatures caused by friction, impact or frictional sparks
Explosion hazard!
Fire hazard!
Damage to the pump set!
▷
Regularly check the cover plates, plastic components and other guards of
rotating parts for deformation and sufficient distance from rotating parts.
7.2.2.1 Checking the clearances
If the clearances need to be checked, remove the impeller. (
⇨
Section 7.4.6 Page 35)
If the clearance is larger than permitted (cf. table below), fit new casing wear ring
502.1 and/or 502.2.
The clearances given refer to the impeller diameter.
