TRAILER CONCRETE PUMP
OPER.
PAGE 22
The pressure by which the concrete is being pumped
is based on the ratio between the hydraulic cylinder
and the material cylinders and that is divided into the
hydraulic pressure being applied to the drive
cylinders.
In this instance the ratio is 2.25 (piston side) and the concrete pressure is calculated as
follows:
SYSTEM GAUGE-PSI CONCRETE PRESSURE PSI
1000 440
2000 889
3000 1333
3500 1556
4000 1778
4200 1867
On the other hand the hydraulic pressure being applied to the drive cylinders is controlled
by the amount the
VOLUME control is opened. When turned to the FULL OPEN position
this will produce approximately 4200 PSI on gauge.
PUMPING TIPS AND PRECAUTIONS
Your SAFETY is our utmost CONCERN and it is your RESPONSIBILITY to operate the
equipment in a SAFE manner. The following TIPS and PRECAUTIONS are offered as
AWARENESS facts and should be OBSERVED for proper safe operation.
•
Always maintain the material level in the hopper to no less than the height of the
remixer shaft height or 1/2 full. This is IMPORTANT otherwise air will be sucked into
the material cylinders and the continuous smooth flow may be interrupted.
•
The concrete output is influenced and related to the quality and consistency of the
concrete mix. Mix consistency is a decisive factor when it comes to the filling rate of
the material cylinders.
With stiffer consistency and unfavorable grading curve of the aggregate, (smaller portion
of sand, crushed materials) the rate of filling the material cylinders becomes less efficient
resulting in a lesser concrete output. When you encounter this condition it is suggested
that pumping at a slower speed can positively increase the output by allowing more time to
fill the material cylinders.
