Recovery of oil (high pressure and cycling)
For intermittent
pumping
For cyclical pumping
When the pump operates at high pressure, the oil heats up, becomes more fluid
and is flushed out of the functional block by the gas stream.
Oil losses at the exhaust are increased.
If the pump only operates for a very short time at high pressure,
the lubricating oil is replaced when the pump returns to low pressure. The use of
a oil mist eliminator prevents losses due to intermittent high pressure operation.
If the pump operates at high pressure in a cyclical fashion, oil consumption may
reach sufficiently high levels (according to the pumped volume and pumping
cycle rates) causing the level to drop in the oil case.
There is then a risk of seizure due to a lack of oil. In addition, the high flow of
gas passing through the eliminator prevents oil from returning to the oil case.
In order to pump in these conditions, the pump must be equipped with an OME
25 HP type oil mist eliminator and an ODK oil draining kit, which enables oil
recovery via the gas ballast.
For continuous pumping at
high pressure
In this case, or when very large volumes (requiring several hours of pumping)
are being pumped, it is recommended to recover the oil via the pump inlet.
In this case, please consult Alcatel directly.
Cyclical pumping:
ODK type oil recovery device
OME 25 HP + ODK 1
Device is not tight
when switched off.
OME 25 HP + ODK 2
An electrovalve ensures
tightness when switched off.
