CP-563 Vibratory CompactorsThe above compactors were designed with high and low amplitude and the ability to vary the frequency from 1400 to 1800 vpm. This allows the machine to be used over a wide variety of soil conditions and job specifications to achieve compaction.
Several factors influence vibratory compaction effort. The characteristics of the material to be compacted play a part in the dynamics of compaction. Soil types, gradation, texture, moisture content, layer thickness, subsoil base and its supporting capability all influence compaction.
The design of the machine is also important to the dynamics of compaction. Frame size, overall weight, ratio of weight supported by the drum compared to the axle, drum width and diameter, drum mass, eccentric weight mass and the distance between the eccentric center of gravity and drum axle are factors considered in the design of the machine.
Compactive effort is also influenced by the operator. Drum movement up and down (amplitude), speed of the eccentric weight (frequency) and moving forward (working speed) are all variables which are controlled by the operator.
It is the combined characteristics of the compactor and of the soil it is attempting to compact which determine the degree of compaction effort.
Periodically certain combinations of machine variables and the soil produce a condition called drum decoupling. Drum decoupling is a condition where the drum and the soil resonances are working against each other which slows the overall compaction process. This can be indicated by the drum becoming uncoupled or separated from the material being compacted. Continued operation of the machine while the drum is decoupled may shorten the life of machine components.
Decoupling typically begins to occur as the soil compaction density increases and as the vibratory system operating pressure increases. To minimize decoupling on these machines, an operator should first decrease the frequency if working in high amplitude. If decoupling still occurs, low amplitude should then be selected and the frequency should be adjusted to the point at which the decoupling is at a minimum, typically 1500 vpm. By using the amplitude selection switch and variable frequency feature, an operator should be able to achieve the compaction requirements for a wide variety of job applications.
Beginning with 1YJ152, 8XF263, and 7GG45, the maximum frequency for low amplitude is set to 1500 vpm by the use of vibratory pump mechanical stops. This frequency was selected to assist the operator in minimizing drum decoupling in most job site conditions. If job conditions require variable frequency in low amplitude, then the maximum frequency can be readjusted to 1875 25 vpm.
