Hydraulic System
1. Safety rules of high-pressure oil
The inside of the hydraulic system always
have the pressure. When check or replace
the pipeline or the soft pipe, do check
whether the pressure has release or not. If
there is pressure, it will make a serious
hurt or destroy. Do as follow:
1) When the hydraulic system has
pressure, do not check or replace.
2) If the pipeline of the soft pipe leaks
and in wet area, please check the
pipeline or the soft pipe whether it is
broken or dilates. The operator should
wear the safety glass and the glove to
check.
3) If the high-pressure touch the eyes, it
will be dangerous of ablepsia. Use the
clean water to wash the eyeS or the skin which touch the high-pressure,
and go to the hospital.
2. Safety operation of the high-pressure soft pipe
If the high-pressure leaks, it will make the fire or the operation trouble and lead
the serious hurt or destroy. If the bolt is loose, stop the machine, and screw it
down. Do not weld the machine when the hydraulic oil pipeline (soft pipe) is not
separate. If the soft pipe is broken, do stop operate, and contact us.
If any problems as follow happen, do replace the soft pipe:
1) The tie-in of hydraulic pipe leaks or is destroyed.
2) The envelope is broken or apart, or the steel wire of the reinforcement is
out.
3) Some parts of the envelope dilate.
4) The mobile parts contort.
5) The envelope has impurities.
3. Safety rules of the high-temperature oil
The hydraulic oil which is cooling on working or after working is
high-temperature and high-pressure. Do avoid the oil squirting or touching the
hot parts. Before operating, the oil should be cooling. Do loosen the cover or
staff before unload them even if the oil has been cooling.
