Preliminary Checks; Operation; Stopping; Maintenance - Rico Ric T40D Manuel D'instructions

13.1

PRELIMINARY CHECKS

Before starting the machine for use, carry out the following preliminary checks:
•
If the unit has not been started up for some time, check its condition and, if necessary, remove any dust from the external surfaces;
•
Deactivate/open any pipe closing devices (shut-off valves, solenoid valves, etc.) before starting the unit.
•
Never start and operate the unit with the inlet and/or outlet port closed!
•
Make sure the ambient and conveyed gas suction temperatures come within the values: -15°C (+5°F)÷ +40°C (+104°F);
•
Check correct operation of the pressure-relief valve (not supplied).
13.2

OPERATION

The unit can be started for use after carrying out the preliminary checks.
•
Start the unit by switching on the power to the electric motor.
• 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 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
When in operation the blowers / exhausters can reach high surface temperatures.
Before carrying out any operation after shutdown wait at least 20 minutes for the unit to cool.
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.
