Maintenance

Oil Plugs / V entilator

. Prior to removing plugs, ensure that the pump

has cooled sufﬁ ciently so that oil will not burn.

emove ventilator plug prior to removing level

and or drain plug.

WARNING

Do not stand over ventilator plug while
removing as pressure build up behind valved
ventilator may cause it to eject when removed.

. Place a container under the oil drain plug to be

removed.

OTE:

It is recommended that the oil should
be slightly warm ( 104 ° F – 122° F [ 4 0° C –
5 0° C] ) when drained. Cooler oil will be

more difﬁ cult to drain correctly.

BEARING LUBRICATION

here re-greasing points are provided, add

shots monthly of

grade grease.

CLEANING

ith the drive stationary, periodically clean any

dirt or dust from the gear unit and the electric

motor cooling ﬁ ns and fan guard to aid cooling.

( mm).

OIL SEPARATOR

All D- and D- blowers built since October

are ﬁ tted with oil mist eliminators in the oil

separator. f the oil separator has a ﬁ lter, it will be

necessary to periodically replace the ﬁ lter element

and remove any sludge accumulation.

The frequency of this is dependent upon the

following conditions

•

isual inspection shows the element to be

blocked by foreign matter. A back pressure

through the ﬁ lter element e ceeding P l

indicates that the ﬁ lter element is unduly

restricting the gas ﬂ ow and should be changed.

•

Motor current exceeds manufacturer’s

speciﬁ cations.

•

A ruptured element or the gaskets are not

sealed, allowing mist to be discharged.

The oil separator on D- A and D-

pumps

is equipped with an oil drain-back device to return

oil to the reservoir that has penetrated the ﬁ lter

element. The check-type drain-back closes to

prevent the e haust gas from bypassing the ﬁ lter

when the inlet pressure is high and opens to

allow the oil to drain back as the inlet pressure

is reduced. f the pump is operated at high inlet

pressures, over Torr, for time periods e ceeding

several hours, no drain-back can occur and ﬁ lter

efﬁ ciency is reduced. nder such conditions,

isolate the pump from the system with the main

isolation valve, and run at blank-off pressure for

minutes to allow the oil to drain back. f

the pump is always operated with lengthy high

pressure, then install an e ternal oil return line as

follows.

A return line can be installed to return oil that

collects in the ﬁ lter area back to the pump.

The successful operation of this arrangement

is dependent upon having the oil return to the

pump at a point that is compatible with the pump

operating pressure level.

See Figure 7-1 on page

. enerally, oil must be returned to a low

pressure point. The oil separator has an oil return

valve that allows oil ﬂ ow back when operating at

pressures below Torr.
