FUNCTION OF EACH PART
n
nn
n Through bolt
Front head, cylinder and back head of breaker body
are secured with four through bolts.
Cylinder
Hydraulic circuit for reciprocating the piston and
valve are built in. The cylinder is the heart of the
breaker body .
Accumulator
The inside is charged with high-pressure N2 gas.
The accumulator compensates for pressure in the
hydraulic circuit and prevents pulsation. (See
"Charging accumulator with N2 gas and inspection
of charge pressure," p.3-14. )
Piston
Kinetic energy of the piston is converted into
hammering energy when the piston hits the rod, and
consequently rock is broken.
Front head
The front head supports the entire breaker with the
front bush built in because of the shock transmitted
from the rod .
Rod
A flat rod, wedge point, and moil point can be used
in accordance with application.
(See "Types of rods and major applications," p.2-6.)
Valve adjuster
This valve adjusts the oil consumption of the
breaker. The number of blows and oil consumption
are increased by opening this valve
counterclockwise, and decreased by closing it. (See
“ADJUSTMENT OF ADJUSTER”, p.3-13.)
