Vertical 150 Gallon Foam Bladder Tank System For Fire Fighting

INTRODUCTION

Foam bladder tank is the key unit in foam extinguishing system. Foam bladder tank system provides foam solution for all kinds of foam discharge devices such as foam chamber, foam generator, foam branch pipe, foam sprinkler, etc. 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.

PRINCIPLE

Foam bladder tank consisty of bladder tank, rubber bladder, foam proportioner, pressure gauge, control valves and pipes. 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.

PARAMETERS

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)
