Section 2 - Components
Vacuum Hoses
A 3” vacuum hose with quick connect fittings runs
from the debris tank inlet to the vacuum fitting
on the Ground Hog blasting head. Consistent and
proper vacuum is important to the proper opera-
tion of the vacuum system. Debris buildup, kinks,
damage or leaks will cause reduced air flow at the
blasting head, reducing efficiency or cause opera -
tions to stop completely.
Many problems with vacuum hoses are caused by
damage or kinks. You should avoid tight bends and
maximize the radius of all hose curves to minimize
the chance of a kink. It is very important to protect
the hoses from contact with sharp objects, abrasive
surfaces, foot or wheel traffic and to inspect the
hoses daily to ensure there is no damage or kinks.
The inside walls of vacuum suction hoses develop
wear points caused from the high velocity of abra-
sive debris traveling inside the hoses. The wear
points are most prevalent in the outside radius
of tight bends near the blast head and where the
debris hose rises to connect to the vacuum power
unit. The life of the hoses in these areas can be
extended by rotating the hoses 120 degrees once
each week.
Some types of debris will buildup on the inside walls
of the vacuum hoses to the point where it restricts
debris flow in the system and reduces vacuum at
the blast head. Debris buildup inside the hoses
can be removed by tapping the outside walls with
a dead blow hammer while the system is operating
at maximum vacuum. This will flex the hose walls
and cause the debris to break off and be sucked
into the debris tank.
Damaged areas can be repaired by cutting out the
damaged area and splicing in new hose. Temporary
repairs can be made using duck tape.
Make sure to protect the hoses from damage and
abrasion from dragging on the pavement. This is
particularly important when working a long distance
from the vacuum power unit. In some situations
anti-chaffing protection may need to be added to
the hoses in contact areas.
Vacuum Hose Connection
Notice seal inside connection. Always make sure the seal is
in place before connecting the vacuum hose.
