1
Basic working principle of
Hydra-Pneumatic hammer
The basic working principle of HydraPneumatic hammer is energy conversion
from pressurized liquid into compressed
gas and from potential energy of
compressed gas and kinetic energy of
falling parts into blow energy.
Pressurized oil from the pump and
accumulator pushes the piston upward and
compresses the nitrogen, when the quick
release valve fully opens, high pressure gas
pushes the piston down-ward rapidly and
accelerates the falling part during working
stroke , a hammer blow with
stipulated ,kinetic energy is formed.

Technical characteristics
of Hua-an Hydra-Pneumatic
hammer ：
•High instantaneous velocity
•high blow energy
•high blow rate
•high quality of forged piece
•energy saving
•more possibility to completing the forging
with one heating .

1. Hydra-Pneumatic hammer
constitution
Power head, hammer tup, piston rod, hammer
body, tup guides, top pallet, bottom pallet.
Power head including the main body,
accumulator, buffer cylinder, gas cylinder,
piston rod cylinder and bottom gland seal.

1.Eletro hydraulic hammer constitution
1）Upper tank
This is a critical part of the
hammer, it connects the hammer
legs and holds the main
components, comprising of
control valve, oil discharge valve
and safety valve.

Third, unique feature

2）Accumulator (right)
It is an indispensable part of
the hammer it is divided into
an upper gas chamber and a
lower oil chamber by a piston.
It is used for storing
compressed gas and
pressurized oil
respectively .It provides
pressurized oil for the fast
movement of the hammer.

3）Gas cylinder and oil
cylinder (left)
Oil cylinder having a piston inside is
surrounded by a gas cylinder. The
space between the two cylinders is
filled with compressed
nitrogen .The top of gas cylinder is
open to the gas cylinder and the
lower part of the oil cylinder is filled
with pressurized oil .The pressure
difference between oil and gas
produces the hammer movement.

constitution
4）Buffer cylinder
It is a very important part for
safety protection and is
composed of; a cylinder ,
piston, cover and
spring .There is low pressure
nitrogen in the upper cavity .
When the piston rod returns to
the top of the gas cylinder too
fast, its excess kinetic energy
is absorbed so avoiding the
cylinder cover breaking away
and further damage

5）Main gland seals
They are important parts for
sealing high pressure oil in the
lower chamber of the oil cylinder
and positioned at the bottom of
upper tank .They are also the
guide for piston rod. Seal of
“high-low pressure combination”
and fixation of “duplex clamping”
have realized dual purpose of
safety and reliability.

6）Ram piston rod and
their connection
Ram and piston rod are designed
and manufactured according to
international standards to assure
their strength and rigidity under
alternating stress after long term
use. The piston rod is reliable for
five years under normal conditions.
They are connected using a taper
for convenient maintenance
without damage to the ram.

3. Electrical system characteristic
Design purpose of the electronic
system is “reasonable structure
and advance performances for
stable ,reliable running
,sensitive control ,low failure，
long life”，
All components are available
locally.
The electrical system meets all
current EU directives.

Fourth, The conversion process from air to
Hydra-Pneumatic
The
process is that using hydraulic
power head substitutes the original air
cylinder with the power head, guides,
pump station, electronic control
system and nitrogen gas system.

Fifth, Hydra-Pneumatic hammer safety systems
The hydra-Pneumatic hammer is a high speed
reciprocation unit that creates intense vibration, for
the guaranteed of equipment under normal operation
and man-machine security, we adopted a "quality first,
safety first" principle, we have successfully developed
many protective measures within the control system
Hydra-Pneumatic hammer safety technology introduction
Hydra-hydraulic hammer safety measures
1. Oil temperature over temperature with automatic
cooling
2. Oil level monitoring automatic system shut down;
3. Filter blockage system;
All pumps are automatically monitored;
4. Pressure test automatic monitoring system;
5. Main gland seal leakage monitoring system;
6. Pipeline bursts protection system;
7. Hammer piston rod monitoring protection system.

2. Hydraulic pressure station
characteristics
Hydraulic station is a pressurized
oil supply system for the storing
and releasing high pressure oil. It
includes oil tank , motor ,
Hydraulic pump , Hydraulic valve,
refrigerator, Hydraulic oil ,
system of gas storage. The design
purpose is “reasonable structure
and advance performances for
stable and reliable running
