The compressor is equipped with a suction filter, it is still suggested to install a suction filter on the suction pipe
and clean it regularly, so that it is convenient for cleaning and replacement, with double protection at the same time.
When the system starts to operate, if the pressure drop is found greater than 0.5bar, please clean up filter. If the filter
is found damaged, we need to replace it in time, and clean up the impurities in the pipeline. During installation,
please ensure the correct direction of the filter. The stop valve is suggested to be added at the inlet and outlet for
easy maintenance.
2.3.2
External oil circuit system
If the compressor operates under low temperature conditions and the lubricating oil does not have extra cooling,
it will be unable to meet the operation requirements because of the high oil temperature. At this time, it is suggested
to configure the external oil cooler which can reduce the discharge temperature, and can also prolong the life-time of
the system.
Note:
The temperature of the inlet oil should not be higher than 60
℃
.
There are mainly 3 type of oil cooling system:
Air cooling type
Water cooling type
Refrigerant cooling type
The heat exchange data of the oil cooler can be obtained by the HANBELL model selection program. The limit
operating conditions should be taken into account, such as the maximum pressure difference (high condensation
temperature and low evaporation temperature).
