1. Install pump near the suction water level
1-1 Suction head is varible to the pump, but generally if the
suction head is higher then 7~8m suction
Will be impossible.
1-2 The larger the diamerter of pipe is, the slower becomes
the flow velocity. So because loos is
Reduced in case of larger diametem suction head is also increased.
2. Suction pipe shll be installed highest on the side of pump,
and be installed iow by inclining it toward
The suction water level. Therer is no problem if the water level
on the side of suction is higher than
The pump, but if there is any place(Wform) where the pipe rises
up and fall down back even though
the pipe is installed lower than pump in piping the side of
suction, the pump will not work.
3. Set up the center of coupling exactly before operating
pump because the center of motor and pump
Has been fixed by the manufacturer, it is necessary to correspond
them again.
4. Fix the center of coupling bolt, and be sure to separate
the couplings at an interval of 3~5mm. Be
Sure to screw the boll and not of coupling fast, because they
may be loosened in the operation.
5. in case that there is any oil ring in metal or bearing
parts, be sure to check that it turns smoothly
immersed deep in lubricant.
6.Be sure to check whether the pump and the motor rotate
in the same direction.
7. Fist prime the pump just before operation it, and if
water does not flow, stop the operation immediately
And prime the pump.
8. The pump will be broken if you rotate it in the reverse
direction, so the rotation in the reverse
direction is prohibited adsolutely.
9. In case of a general pump, open the delivery valve gradually,
but in case of axial flow pump, open the
Valve fully before the operation.
10. check whether ther occurs overload, by checking the noise
vibration oil ring and measuring the
Current.
