Haldex B Serie Manual Del Usuario

Air Inlet
A. The compressor should never be used without an inlet
filter. A dirty or restricted filter will affect performance and
cause the compressor to pass an excessive amount of oil.
The maximum inlet restriction with the compressor running
at 2400 rpm and pumping to atmosphere is 20 inches of
water. If intake vacuum exceeds 20 inches of water , the
intake filter must be changed. Haldex compressors in the
EL or EL(X) series may be supercharged up to 35 psi inlet
air pressure. Warranty is given in supercharged service for
all compressors in the EL or EL(X) series.

A. Clean air is necessary to prevent excessive cylinder and
ring wear. It is also necessary for operation of brake
valves operating under close clearances.
Drive System
A. The compressor installation and drive system has an influ-
ence on compressor life. The compressor is designed to
operate with certain speeds and mountings. If the operating
speed is too slow, insufficient air supply may result. On the
other hand, a very high speed will shorten compressor life.

EL1300, EL1600 or EL3200 Compressor:

Governor Mounting
A. Inspect the reservoir to governor line. The line must
be free of contamination and kinks.
CAUTION The exhaust port of any governor must be open
!
to the atmosphere. If the reservoir to governor line is too
short, use kit SN4011F (this will add eight inches to the line).
B. Keep Governor as Close To Compressor as Possible.
The line between compressor governor and unloader
must not be greater than 5/16 inch ID or longer than five
feet. Erratic governor performance may result when the
discharge line is beyond those limits.
C. Keep Governor Away from Engine Hot Spots.
Excessive heat is detrimental to the rubber seals in the
governor; therefore, some thought should be given as to
its location. This also applies when mounting the
governor to the compressor – the governor should be
placed as far from the compressor discharge as possible.
D. Governor Supply Line Must Be 1/4 Inch ID Minimum.
When the governor opens, air passes through the gover-
Filter nor and fills the unloader pins cutting out the compressor .
If the governor supply line is restricted, a pressure loss at
the governor supply may close the governor valve and
exhaust the air in the unloader. As soon as pressure builds
up again at the governor, it will reopen. This cycle will con-
tinue at a high rate. To avoid this "flutter" condition, the
governor line should be at least 1/4 inch ID and should not
be restricted by fittings or sharp bends. It is also recom-
mended that this line be as short as possible and be inde-
pendent from other accessories requiring a supply of air .

A. Inspect installation for air pressure, coolant or oil leak-
age. Listen for any noise which may indicate loose
mounting or poor drive gear alignment.
Governor Function
A. Build up air system. Observe cut out pressure (maximum
system pressure), "pump" foot control valve until compres-
sor starts pumping again (minimum system pressure). The
most common pressure range is 105 to 125 psi. Your fleet
may require different pressure levels which can be adjusted
by changing the governor setting.
