Vibratory System Schematic
(1) Vibratory pump. (2) Directional control valve. (3) High pressure relief valves (two valves). (4) Oil filter (vibratory charge pressure). (5)
Flushing relief valve. (6) Vibratory motor. (7) Vibratory charge pump. (8) Hydraulic servo. (9) Charge pressure relief valve. (10) Flushing
valve. (11) Oil strainer. (12) Hydraulic oil tank. (13) Hydraulic oil cooler. (14) Thermal bypass valve.
The vibratory system consists of the following components:
vibratory pump (1), oil filter (4), vibratory motor (6), hydraulic oil
tank (12), hydraulic oil cooler (13), and bypass valve (14).
The charge oil for the vibratory system is supplied by the
charge pump (7). Charge pump (7) is a gear type pump that is
integral to the vibratory pump (1).
Two vibratory systems are available.
The dual amplitude system is a standard for the
The variable frequency system is an option for the
The adjustment of the pump swashplate angle is the only
change between the two vibratory systems.
The throttle switch has two sets of contacts. The
throttle switch must be in the high position for the
vibration to work.
