Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pump for fire extinguishing,

The present invention relates to an equalization pump for evacuating a forest fire, and more particularly, to an equivalence pump for forest fire evolution capable of easily charging the equalization pump without disturbing the digesting water and realizing the amount of charge even during charging.

Generally, when a fire occurs in a large area such as a hill, the evacuation personnel are put in order to extinguish the fire. In this case, the fire extinguisher is a fire extinguisher.

Conventionally, an equalization pump used in a forest fire evolving operation is composed of a water reservoir and a compression piston having nozzles at the end of the hose connected to the lower end of the water reservoir. When the back pressure pump is used, the operator grips the end portion of the hose, that is, the nozzle portion, and the other hand pumps the compression piston to compress the water by the pumping pressure.

Most of the inside of the backflow pump is filled with fire extinguishing liquid such as water in the inside of the container and it goes up to the fire scene. In the process of rising, the connection hose connecting the container and the injection pump frequently catches around the branches. Therefore, it is not easy to move quickly to the fire site. In summer when fire is not frequent, there is a problem that a large storage place is required due to the protruding connection hose.

In addition, there is a problem that it is difficult to fill water when the water contained in the backflow pump is exhausted. In other words, there is no valley water in every mountain. Even if there is water in the valley, even if you go down to the valley, fill the water and then load the heavy load pump again.
