6. How to use
1)Start and stop
(1)
Connect air piping to air supply port ”AIR SUP”, and fluid transfer piping to suction port
“FLUID IN” and discharge port ”FLUID OUT”.
3-port solenoid valve (N.C) needs to be prepared separately to turn ON and OFF the pilot air
which is supplied to the air supply port.
(2) Set pilot air pressure within the range 0.2 to 0.5MPa.
Start operation by applying ON/OFF signal repeatedly to the solenoid valve prepared separately.
After a while, the fluid will flow from the suction port “FLUID IN” to the exhaust port “FLUID OUT”.
It sucks by itself without priming. (Suction pump head : 0.5m Normal temp. / clean water)
(3) To stop the pump, stop the solenoid valve, and make sure to exhaust all the air inside the pump.
Although the pump is stopped by closing the valve installed at the discharge side, avoid stopping
operation for a long time in this way.
If the valve closes suddenly, surge is generated, shortening the pump life.
2) Adjustment of the discharge amount (Typical circuit )
(1) The flow rate changes by changing the switching time (Operation cycle) of the solenoid valve
ON/OFF signal.
(2) Use the ball valve connected to the discharge side to adjust the flow at the fluid side.
(3) When exhausting air, using a meter-out will reduce the suction speed of the fluid and so
reduce the generation of bubbles.
