3.3 Water Piping
Take out the R3/8 plug on the Coolant inlet/outlet and put the joint (of nylon tube) for the water
piping.
(Refer to the “Fig. 4 Lubrication and water piping drawing”.)
Be sure to flow the Coolant with the volume indicated on the Table 1
Performance specifications or more. The pump temperature would rise
up if the water volume becomes less than specified particularly on high
suction pressure operation and cause the pump failure. You are
recommended to put a Flow meter for the Coolant and cause the
interlock so that the Pump stops if the coolant flows less than specified
volume.
When the operation stopped in winter, the water piping and Jacket have
a risk of breaking by freeze-up of the water inside. Open the Coolant
drain of the Jacket (Refer to Fig. 4) during operation stop to discharge
the water inside by blowing in the pneumatic air through the water inlet.
The water included little impurities (ex. Industrial Water) is
recommended for cooling water.
Depending on the water quality, the inside wall of cooling water tube is
covered with water scale (CaCO
3
etc.) and cooling water flow rate may
be decreased. Cooling water tube is corroded by Chlorine ion (Cl - ) and
cooling water leak may be caused. In case of using pure water, cooling
water leak may be caused by metal component dissolution, too.
In these cases, the repair service may be for a fee.
