How to fill foam tank with foam liquid
Jan 01, 2024

Fitted foam solution: be prepared to state the capsule fill preceded foam concentrate. Usually a pump filling, you can manually filling, concrete steps are as follows:
Filling the tank foam liquid should first open the exhaust valve 6, capsules exhaust valve 8, and should open foam liquid filling cap 7, close the liquid valve 3, the drain valve 11, the inlet valve 4, the drain valve 10;
4 to open the inlet valve body and the capsule filling sandwich 300-1000L water, the capsule floating, fully expanded;
then connect bubble liquid filling pump irrigation fluid hose insertion port 7, open bubble liquid filling pump, it can send the foam liquid into the capsule, while opening the drain valve 11 is slowly discharged water tank and capsules mezzanine. Filling a sufficient amount of foam liquid or foam liquid filled capsule from the capsule filling overflow exhaust port 8, stop feeding liquid.
filling end, should ensure that the inlet valve 4 and the liquid valve 3 normally open (except for a wet pipe system), the rest of the flap valves and flanges normally-off device to be prepared to enter the normal state.
also available through the drain valve 10 filling foam liquid, liquid filling without opening the cap.
7.2 Use and operation:When the other components of the device systems and fire pumps, piping, etc., the inlet valve 4, the liquid valve 3 must maintain the normally open state (except for a wet pipe system), and only in such a state, after receiving fire After the alarm, immediately start the fire pump, open proportioning valve outlet pipe on the road leading to the fire department, the foam can be sprayed automatic fire.
3. Replace the foam fluid: foam liquid after use or storage period expired, and should the new foam filling liquid. Before filling capsules respond fully cleaned. Open the drain valve 11 and drain valve 10, put in to make the rest of the foam liquid capsule, then the capsule from the exhaust valve 8 connected compressed air foam residue Chuijin capsule. Close the drain valve 10, from the irrigation fluid outlet 7 into the capsule inside the capsule surface clean water to fill, and finally open the drain valve 10, connected to the compressed air from the valve 8 will water out, and continue to use the compressed air spray Capsules 30min, the water inside the capsule completely dry, refilled bubble liquid.
If the foam concentrate pump installation, pump after each installation should be cleaned with water, so as not to dry foam liquid pump impeller and pump viscous to death, the pump motor burned out.
4. Use of the gauge: the observation level, should open the tank vent valve 6 and exhaust valve 8 capsule, ensure no pressure inside the tank, and capsules, and then close the valve 6, the valve 8. Then open the gauge inlet valve, liquid level gauge is on the inside of the capsule at this time. Close observation should be finished immediately gauge inlet valve, and open the drain valve gauge emptying liquid level gauge in the foam.
