High-Temperature Prevention
DANGER
We suggest that in order to pick up materials with flash
points below 300°F, primary and backup system sensors
and air flow modifications to limit operating temperatures
should be made to a standard vacuum system as
manufactured by Super Products. They include the
addition of two temperature gauges with adjustable
switches, and two temperature sensors, which should be
installed in the exhaust airstream of the vacuum pump. In
addition, two air-operated valves should be installed on
the body. The temperature sensors and gauges should
be similar to a Murphy temperature “switch gauge”
whereby a contact closes, permitting use of an electrical
signal at temperatures above an adjustable preset
temperature. The valves should have a minimum four
inch diameter.
In operation, the operator should set the trip point of the
temperature switches at or below the flash point of the
material being picked up. If the exhaust temperature
reaches the set point of the temperature switch, the
valves would open. This would stop the conveyance of
material through the vacuum hose, permit cool air to be
sucked into the body and vacuum system for cooling the
vacuum pump, and quickly vent from the body so as to
not cause an explosion. Prior to each load being
vacuumed, the operator should test each system to
ensure the valves are working.
The operator should set the trip point of both Murphy
gauges to the lowest possible setting, block off the intake
hose, and operate the vacuum pump at a minimum of
1000 RPM until the temperature rises to the trip point.
The operator should ensure that once the temperature
has reached the trip point, the respective valve opens.
DANGER
Failure to comply with the recommendations for
high-temperature prevention could result in
equipment failure, personal injury, or death.
Do not use the unit unless both temperature
limitation systems are working properly.
