VACUUM SYSTEM MAINTENANCE
The vacuum pump in this machine is commonly referred to as a “rotary positive
displacement blower” or “blower” for short. The performance and life of the truckmount is
greatly dependent on the care and proper maintenance it receives. The manual for the
blower has been included. Review the manual for a better understanding of this piece of
machinery.
To protect the blower from overloading and damaging itself, there is a vacuum
relief system installed on the vacuum tank. When the vacuum tank inlet is
completely sealed off a maximum of 12” Hg will be attained.
Solid objects entering the blower will cause serious damage to the internal
components of the blower. Extreme caution should be used when the truckmount
is being run for test purposes with the inlet to the blower open to the atmosphere.
Foam passing through the blower can lead to serious problems with the truckmount.
It is important to keep the vacuum tank free of foam. The tank is protected from
overflowing by a float kill switch; however, this switch is not activated by foam.
Daily
At the end of each day the internal components of the blower need to be lubricated. This
helps to prevent rust deposits and prolongs the life of the truckmount.
To lubricate the blower:
1. Allow the unit to run for a few minutes with the vacuum hose disconnected in order
to remove moisture from the blower.
2.
Cap off the inlet(s) to the vacuum tank.
3. Spray a HydraMaster-recommended spray lubricant into the “BLOWER LUBE
PORT” for about 5 to 7 seconds while the unit is running.
4. Uncap the inlet(s) and run the unit for another minute to allow the blower to cool
down.
Periodically
Change the oil in both ends of the blower after the initial 100 hours of use. The oil is to be
changed each 500 hours of use thereafter.
