Stopping; Maintenance; Periodical Checks - FPZ SCL K05 Instrucciones

•
Check the operating pressure or vacuum and also compliance with the values given in the "SPECIFICATIONS". Pressure losses in
the pipes are often underestimated but are decisive factors for the operating differential pressure.
•
Measure the motor absorption and check compliance with the rated value.

13.3 STOPPING

•
The unit must be stopped by switching off the power supply to the motor.
•
In case of shutdown, make sure to operate the unit with the inlet open for about 20 minutes.
This operation allows the removal of any condensate in the suction chamber.

14 MAINTENANCE

In order to prevent faults and damage it is important to periodically check the units in operation, therefore it is advisable to adopt a
maintenance plan in line with this Manual, providing for:
•

Periodical checks

•
Periodical maintenance and troubleshooting
14.1 PERIODICAL CHECKS
The units in operation should undergo periodical inspections by qualified personnel, in order to prevent failures that can directly or
indirectly cause damage.
A) With the unit in operation periodically check the following parameters:
•
Delivery temperature
•
Operating pressure and/or vacuum
•
Electric motor current absorption
•
Vibration
•
State of the filter and corresponding pressure loss
In operation the machines can reach high surface temperatures, up to 125°C (+257°F)
- Before carrying out any operation after shutdown allow the unit to cool by waiting at least 20 minutes.
Considering continuous use, provide for periodical calibration of the measurement instruments according to the
ATTENTION
regulations.
Vibration values higher than Zone B (table of effective vibration velocity value) are considered NOT permissible and can cause damage
to the machine and therefore serious injury to operators.
- In case of noise and/or abnormal vibration indicating the possibility of seizing of the impeller, move away and turn the unit
off immediately!
Measurement of vibrations
The measurements for determining the vibration velocity [mm/s]
must be done with an electronic vibration meter, at the following
places:
•
Points P1 and P2 (front bearing): place the vibration
meter near the front bearing, adopting the highest
value.
•
Points P3 and P4 (rear bearing): place the vibration
meter on the electric motor casing near the bearing
housing (not on the fan cover), adopting the highest
value.
