Introduction
This manual contains important information regarding
safe operation, adjustment, and maintenance for the
Super Products’ Mud Dog® Vacuum Excavator
.
DO NOT allow anyone to operate or service this machine
until they have read and understood all aspects of this
manual.
DO NOT use this machine for any purpose or application
other than those listed in this manual. Improper use or
neglect of safety precautions will cause serious injury or
death. Refer to Section 1, Safety.
NOTE
This operator’s manual is to stay with the truck and
be used as reference for operator personnel.
Principles of Operation
The Mud Dog is designed for removing soil from around
utilities such as gas, water, electric and telephone lines
as well as in industrial plants for exposing buried lines of
any nature. It can be used for "pot holing" on horizontal
directional drilling sites. It also can be used to dig post
holes for telephone and electric poles as well as many
other applications.
The unit uses a water system for breaking up the soil and
a vacuum system to remove the soil.
The vacuum system utilizes a positive displacement
"Roots" type vacuum pump which is driven by the truck
engine through a transfer case. Material is picked up at
the end of a suction tube and pneumatically conveyed
into a collector body. The vacuum hose is supported by a
boom which, at the operators discretion, can be raised,
lowered, extended, retracted or rotated left or right. As
material enters the collector body, the majority of the
material falls out into the body because of gravity and the
tremendous reduction in air velocity. An air-backed
elbow allows the material to make a 90° bend as it enters
the body while minimizing elbow wear.
The air exits the body at the top front section where the
ball float is located. The ball float will shut off the air
system when picking up materials with enough of a liquid
content to float the ball and therefore prevent overfilling
the unit.
Any material or mist still airborne will then enter a
centrifugal separator which is located just forward of the
large storage compartment on the left side of the unit.
Centrifugal force causes the airborne materials to be
separated from the air stream with the material falling into
a storage compartment located at the bottom of the
separator and the clean air exiting out the top of the
separator.
The air then enters a "final filter" which is a pleated
element capable of ten (10) micron filtration which will
capture any remaining carryover dust.
The clean air then enters the vacuum pump and then
exits out of the vacuum pump through a high efficiency
exhaust silencer and into the environment.
The Mud Dog™ is designed to pick up wet materials as
well as slurries. If picking up dry materials that are dusty,
you must wet the material down to limit the carryover into
the separator and final filter.
