DESCRIPTION OF HYDRAULIC SYSTEM
The hydraulic system of the
00 MODEL C50SS consists of three separate circuits and
although integrated, each is designed to perform a particular function within the operation of
the concrete pump. The three circuits utilized are:
•
Main Pump Circuit - It controls the function for operation of the hydraulic drive cylinder
and material cylinders.
•
S-tube Shift Circuit - It controls the function for operation of shifting the S-tube from
one material cylinder to the other during concrete pumping.
•
Auxiliary Circuit - This controls the operational function for the agitator/remixer.
For the purpose of making the operation of each circuit easier to understand, they are being
described separately.
SPECIFICS – PRESSURES
•
Main System Max. Pressure = 4700 PSI (327 Bar)
•
Main System Relief Pressure = 4200 PSI (294 Bar)
•
S-tube Shift System Relief Pressure = 2500 PSI (174 Bar)
•
Accumulator Pre-Charge Pressure = 1200 PSI ( 83 Bar)
•
Auxiliary System Relief Pressure = 1800 PSI (125 Bar)
SYSTEM FILTRATION
The hydraulic tank has a capacity of 60 gals (227L) of SHELL TELLUS #46 hydraulic fluid.
The start of system filtration begins inside the tank where two (2) magnetic type suction
strainers are installed. The system return fluid must pass through a 10-micron filter element
before returning to the tank and after passing through the oil cooler.
