[0002] The existing foam proportional mixing system used on fire trucks is a negative pressure foam proportional mixing system. The function of this type of system is: to start the on-board water pump, and to form a vacuum in the foam pipeline through the high flow rate of high-pressure water at the outlet of the pump. In order to achieve the purpose of pumping foam liquid, it is limited to the internal supply of the car. If the water pump stops working, the system will lose all functions

The invention relates to the field of fire-fighting equipment, in particular to a positive-pressure foam proportional mixing system; it includes: a master pump, a foam liquid tank of the vehicle, a water tank, a foam pool, and a main body pump, and the master pump and the foam liquid tank of the vehicle , and the water tank are connected, the master pump, the foam tank of the vehicle, and the water tank are respectively installed on the fire truck, the foam pool and the main pump are respectively installed on the fire truck, and the inlet of the main pump is respectively connected to the fire truck through the pipeline. The vehicle foam liquid tank and the foam pool are connected, and the outlet of the main pump is respectively connected with a supply pipeline for supplying foam liquid to other fire engines, and a vehicle output pipeline for transporting the vehicle's own liquid. It is connected to the water tank through a pipeline, and the outlet of the master pump is connected to the output pipeline of the car; the purpose of the present invention is to provide a foam liquid that can also be supplied to Positive pressure foam proportioning systems for other fire trucks.
Description
technical field [0001] The invention relates to the field of fire fighting equipment, in particular to a positive pressure foam proportional mixing system. Background technique [0002] The existing foam proportional mixing system used on fire trucks is a negative pressure foam proportional mixing system. The function of this type of system is: to start the on-board water pump, and to form a vacuum in the foam pipeline through the high flow rate of high-pressure water at the outlet of the pump. In order to achieve the purpose of pumping foam liquid, and it is limited to the internal supply of the car. If the water pump stops working, the system will lose all functions. Contents of the invention [0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a positive-pressure foam proportional mixing system that can supply foam liquid to other fire trucks while satisfying its own use of foam liquid. [0004] In order to achie...
