Products Description

The principles of the high-pressure pump and foam gun on the Mini Electric Fire Truck are as follows:
The principle of high pressure water pump is mainly through the role of centrifugal force to pressurize and transport water. When the pump is filled with water, the pump impeller begins to rotate at high speed, driving the water to accelerate the rotation. Inside the pipe, the water is subjected to the rotating force of the impeller, which increases the pressure. As the pressure increases, the water is pushed to the water outlet, and the flow rate slows down at the outlet, and part of the kinetic energy is converted into pressure energy, forming low-velocity high-pressure water. This high-pressure water passes through the pipeline system of the fire truck and is eventually sent to water spraying equipment such as spray guns to respond to the fire extinguishing needs of the fire scene.
The foam gun is a special device that mixes the foam liquid with air and ejects it through a high-pressure mechanical pump. The foam liquid is usually stored in a dedicated tank in the Mini Electric Fire Truck, where it is extracted through a pumping system and provided with sufficient pressure. Inside the foam gun, the foam liquid is mixed with air in a certain proportion to form a stable foam liquid. When the foam gun is activated, the foam liquid is sprayed to the fire site through a high-pressure mechanical pump. The foam liquid forms a covering layer on the fire source, which can not only cool the fire source, but also isolate oxygen, thus playing the role of extinguishing and isolating the fire source.
Overall, the Mini Electric Fire Truck high pressure pump and foam gun are the key equipment on the fire truck, and they work together to provide efficient and powerful support for the fire suppression mission. In actual operation, fire personnel will flexibly use these equipment according to the type of fire and the scene situation to ensure the smooth progress of fire fighting.
