ARLINGTON, Va. The vac
uum regulator on your milking
system is one of the system’s most
important components.
It has two major functions: con
trol the vacuum level and compen
sate for many forms of vacuum
usage in order to maintain the pre
sent level. For example, it must
compensate for the intermittant air
admission of the pulsators, unit air
bleeds and other unpredictable
operator events such as put-ons
and take-offs.
Pressure (negative pressure or
vacuum) changes within the milk
ing system occur at very high
speeds approximately the speed of
sound (1,080 feet per second). The
control must react to these pressure
changes rapidly and correct for
sudden air admissions.
The types of regulators that
respond rapidly to vacuum
changes are the servo-diaphram

types. They also are superior in
load sensitivity characteristics.
This means that the vacuum level
is more constant under a wider
range of air flow through the
regulator.
Spring loaded sleeve type regu
lators are acceptable in perform
ance. Dead weight controls usually
are adequate for small milking sys
tems. The lever weight controls are
the least responsive and should be
replaced for better system
performance.
Service the vacuum control on a
regular basis. The operating vac
uum level should be checked each
day. Change filters on a regular
basis. Keep the internal operating
valve clean. A 30-day interval for
servicing the operating valve usu
ally is sufficient
Regulator performance can be
tested with the use of an airflow
meter. Increments of 5 to 10 cubic
feet per minute (CFM) are admit
ted to the system. After each incre
ment the vacuum level is noted
and recorded. An excellent regula
tor will sustain the vacuum level
within Vi inch of mercury when 90
percent of the available vacuum
reserve is admitted to the system.

If the vacuum level drops up to 1
inch of mercury, the regulator is
marginal. If vacuum drops over 1

Cut Soil Erosion Losses
LANCASTER Vast
improvements in seeds, fertilizers
and chemicals often hide losses in
productivity caused by soil ero

slight you never realize the soil is
disapperaring. As a result, severly

don’t have the productive capacity
of other land.. ~
According to Fpr. 1 . Lucas of the

fact is very apparent now. Com

growing.
Lucas said that severely eroded
soils tend to be more acidic, have
lower organic matter and less
water-holding capacity. They are
also more subject to compaction.
As a result crops on these soils are
the first to show moisture stress in
dry weather.
Erosion steals the best portion of
your soil first. Organic matter and
the smallest particles of soil, which
contain the most minerals and
plant nutrients, are easily carried
away by water runoff. Attached to
those particles are pesticides and
commercial fertilizer the landow
ner has paid for and never received
benefits.
