This series of Precise Fluid Dispenser operate by means of air pressure. No high-pressure compression on supply materials is required. For low liquidity fluid, no supply pump is required.
For high viscous materials, ACG series of low discharge pressure Supply Pump or pressure tank is used.
The Precise Fluid Dispenser consists of manifolds to easily increase or decrease the number of discharge ports by means of block plates.
Description of ACV Dispenser Operation
1 Standby(Main plunger goes up and suction)(Continuation from Step)
With the air solenoid valve (SOL-V2) OFF, air in the air cylinder (upper) on the main side is exhausted from A2. The air piston (M) and main plunger rises (up) under the force of spring. In this case, the fluid is sucked below the main plunger, and the dispenser enters the standby state.
2 Pilot plunger goes down
With the air solenoid valve (SOL-V1) ON, Air comes in the upper portion of air cylinder on the pilot side from A1. Along with lowering of the air piston (P), the pilot plunger lowers (down).At end of lowering, the dispensing outlet and the lower passage of main plunger open.
3 Dispensing Process(Main plunger goes down)
With the solenoid valve (SOL-V2) ON, air comes in the upper portion of air cylinder on the main side from A2.Along with lowering of the air piston (M), the main plunger lowers (down). In this case, fluid accumulated under the main plunger is dispensed through the discharge port to the nozzle side.
4 Pilot plunger goes up
With the air solenoid valve (SOL-V1) OFF, air in the air cylinder is exhausted from A1.The air piston and plunger on the pilot side go (up) under the force of spring. In this case, the dispenser draws back the fluid accumulating in the discharge port, preventing fluid dripping. This function is called Suction back.
