A water pressure relief valve is fitted in the water jacket. This
relief valve is set to open at 50 PSIG (3.5 bar).
Standard cooling water rates are for up to 80°F (26°C) supply
temperature and operation within the design of continuous
operating pressure range of .1 to 100 Torr (.13-130 mbar a).
Sustained operation above 100 torr (130 mbar) and/or long
pump downs generally require larger cooling water flow rate
and/or external oil heat exchanger. Larger cooling water rates
increases cooling efficiencies reducing heat dissipation to
room temperature and keeps oil cooler (longer oil life and less
oil loss through the oil mist eliminator).
5.5 VACUUM GAUGES
The vacuum gauge(s) to be installed on the pump must be
selected to meet the requirements of the particular pump
application. Two general types of vacuum gauges are used for
the testing of vacuum equipment, total pressure reading, such
as thermistor or thermocouple gauges, and partial pressure
reading McLeod gauges.
The McLeod gauge indicates the partial pressure of permanent gases. It does not indicate the component
of pressure due to vapor such as water vapor. It is not greatly affected by vapor contamination unless the
contamination pressure is quite high. It is most useful in confirming pump performance and for determining
the absence or presence of leaks. A high reading on a thermistor or thermocouple gauge may indicate
that the pump is contaminated or that it leaks, or both. A high reading on a McLeod gauge means that a
leak is present. Total pressure gauge readings will always be slightly higher than McLeod gauge readings
because it includes the partial pressure due to oil vapor at the localized temperatures. The most accurate
total pressure gauges are capacitance manometers and capsule type or avenvolt bellows type that are
independent of the physical properties of the gas or vapor.
6. OPERATION
6.1 GENERAL
CAUTION
Do not operate without guard in place.
Assure that the guard is in place and secure prior to operation.
CAUTION
Do not operate the pump in an enclosed area unless the pump discharge
is filtered or piped to open air. Prolonged inhalation of oil mist or vapors is
a health hazard.
