Having the right equipment can make all the difference when it comes to fire safety. One such essential tool is the foam trolley, a versatile and efficient solution for extinguishing fires involving combustible solids and liquids. We specialize in manufacturing high-quality foam trolleys and other fire safety products. In this article, we’ll explore how the foam trolley dispenses foam, its key components, and why it’s a must-have for modern firefighting.
What is a Foam Trolley?
A foam trolley is a mobile firefighting unit designed to generate and dispense fire-extinguishing foam. It is particularly effective in combating fires involving flammable liquids, such as oil, gasoline, and chemicals. The foam trolley can operate independently or integrate with larger fixed foam fire extinguishing systems, making it a flexible and reliable choice for various firefighting scenarios.
How Does the Foam Trolley Dispense Foam?
The foam trolley works by mixing water, foam concentrate, and air to create a foam solution that effectively suppresses fires. Here’s a step-by-step breakdown of how it operates:
- Water Supply: The system starts with a pressurized water supply, which flows into the foam trolley.
- Foam Concentrate: The water passes through a vacuum liquid distributor (also known as a proportioner), where it mixes with foam concentrate stored in the foam tank.
- Foam Solution Creation: As the water flows through a narrow section of the proportioner, it creates a vacuum that draws the foam concentrate into the water stream. This mixture forms the foam solution.
- Foam Generation: The foam solution is then directed through a fire hose to a foam gun or foam generation system. Here, air is introduced to the solution, creating a thick, stable foam.
- Dispensing Foam: The foam is discharged onto the fire, forming a blanket that smothers the flames, cools the burning material, and prevents re-ignition.
Key Components of a Foam Trolley
The foam trolley consists of several critical components that ensure its efficient operation:
- Foam Tank: Stores the foam concentrate.
- Vacuum Liquid Distributor (Proportioner): Mixes water and foam concentrate in the correct ratio.
- Fire Hose: Transports the foam solution to the foam gun.
- Foam Gun: Generates and dispenses the foam.
- Control Valve: Regulates the flow of water and foam solution.
