Operation; Maintenance; Routine Inspections - FPZ MS Serie Manual De Instrucciones

Check that the ambient temperature and the intake temperature of the channelled gas are in the range: -15°C (+5 °F) to +40°C
-
(+104 °F);
- Check that the safety valve is working correctly.
- Check that the LED display of the oil level sensor of the mechanical seal is on.

11.2 OPERATION

Having carried out all the preliminary checks, you can proceed with the final starting of the unit.
Start the unit by switching on the power supply to the electric motor.
Check the operating pressure or vacuum and compare it to the values indicated in the "CHARACTERISTIC DATA" table. Load losses
on the pipes are often underestimated but are determining factors for the operating pressure differential. Measure the motor's
absorption and check against the value on the data plate.

12 MAINTENANCE

It is important to inspect the units in operation periodically to prevent breakdowns and possible damage, therefore it is advisable to
adopt a maintenance plan in line with this user manual which requires:
1)

Routine inspections

2) Routine maintenance and repairs
12.1 ROUTINE INSPECTIONS
It is important that the units in operation be inspected routinely by qualified personnel to prevent faults that may cause damage directly
or indirectly.
A) When the unit is running, routinely carry out the following checks:
- Delivery temperature,
- Operating pressure and/or vacuum,
- Electric motor current absorption,
- Vibrations,
State of the filter and related load loss,
-
Level of the mechanical seal cooling oil and relative consumption
-
During operation, compressors / suction pumps can reach high surface temperatures of up to 125°C (+257°F).
- Before starting any work after switching off, allow the unit to cool down!
To measure the vibrations on the rear bearing, it is necessary to remove the protective casing with consequent risk of injury due
to crushing or entanglement!
For this reason, work must be done by qualified personnel taking all the necessary safety precautions. After measurements have
been taken, the cover must be replaced correctly.
Measuring vibrations
Measurements to determine vibration speed [mm/s] must be
carried out using an electronic vibration meter at the points
indicated below (fig. 6.1).
- Points P1 and P2 (bearing box): The vibration meter
must be placed on the cover near the bearing seating, and
the highest value must be recorded.
- Points P3 and P4 (back bearing): The vibration meter
must be put on the spindle near the bearing seating, and
the highest value must be recorded.
The results must be evaluated by comparing the maximum speed value measured with the limits laid down for the zones (A, B) shown
in the table below, in compliance with ISO 10816.
