Data Sheet of Foam Bladder Tank
 
INTRODUCTION
The foam bladder tank is the main unit of the foam extinguishing system. The foam tank and the low/medium expansion foam generator construct the low/medium foam spraying system. It can also construct the high expansion total flooding extinguishing system with high expansion foam generator. It aims at fire of class A and class B, especially for fire of class B. The foam bladder tank mainly applied in occasions such as places where inflammable liquid was produced, stored and transported. It is especially suitable to put out fire caused by inflammable liquid tank or large scale of spill fire.

Foam Bladder Tank for Fire Fighting System


PRINCIPLE
The device consists of pressure tank, bladder, proportioner, pressure gauge, valves and pipeline. A pump is needed to supply pressurized water. When pressurized water flow though proportioner, a small part of water (3%-6%) flow into tank from branch pipe to press the bladder to swap out equal foam concentrate and then mix with another part of water (97%-93%) to form foam solution in proportioner and provide to foam generator.

INSTALLATION
Device should be installed at places with shelter to avoid sun and rain. Ambient temperature should be within 40°C and leave enough space for operation. Device should be installed at concrete floor and fastened with anchor nuts.
Do the hydraulic test after installing. Open the tank vent valve first then fill water into bladder from concentrate draining pipe. Then close tank vent valve when bladder is full of water. Pressurize the system and keeping for 10 minutes when pressure gets test pressure, tank should have no leakage. Close water inlet valve and open water drainage valve and concentrate drainage valve to drain water away in tank and bladder. (We will do this test when products leave the factory)
