Cooling water
- Because cooling water in the pump boils when the
collaboration of cooling water is removed immediately after the
stop of the pump and pressure rises the sensor and piping
might be damaged. Please supply cooling water until the
temperature of the pump falls.
- The pump is very hot during operation and for some time after
it stop. Contact with it may cause burn. Feed cooling water for
about one hour after the pump shut down.
- Close the cooling water supply valve (HWSV). After the valve
is closed, tag CLOSE sign on the grip.
- Through visual flow gauge (HWFM: e.g. flow sight) on the host
equipment ensure that flow is shutoff.
Remove piping
Please do the following work when you drain cooling water from the pump.
1) Compress air is introduced from『Cooling water outlet』of the pump.
2) Work ends if compress air is exhausted from『Cooling water inlet』.
When compress air is introduced from 『 Cooling water
inlet』,the cooling water sensor might be damaged by the load
of compress air. Therefore, please introduce compress air from
『Cooling water outlet』.
Nitrogen Gas
-Close the nitrogen gas supply valve(HPSV) on the host
equipment. After the valve is closed, tag CLOSE sign on the
grip.
- Gas will still remain in the host equipment piping. Place
pressure gauge on the host equipment nitrogen supply source
(halfway of the piping to the pump), and ensure that the
pressure has already down within atmospheric pressure.
Remove piping.
Suction and exhaust gases
<< High temperature surface >>
Be careful of the high temperature surface near this label (intake
and exhaust outlet...).
- Remove the piping according to the manual provided for the
host equipment.
- Suction and exhaust pipe is very hot for some time after pump
stop. Remove the protection cover after about one hour after the
pump is shut down.
-Completely close the inlet and outlet ports with using closing
flange
