Abstract

A rotor mechanical pumping foam proportional mixing device has a hydraulically driven rotor type water turbine taking firefighting water as power, a foam rotor pump connected to a driving output shaft of the hydraulically driven rotor type water turbine by a middle bearing mechanism and used for pressurizing and then discharging normal pressure foam and a firefighting mixed liquid exporting mechanism respectively connected to a water outlet of the hydraulically driven rotor type water turbine and a liquid outlet of the foam rotor pump and used for outputting firefighting mixed liquid. The hydraulically driven rotor type water turbine and the foam rotor pump are both of a driving and driven double-rotor structure, a constant gap exists between the two rotors forming each driving and driven double-rotor structure, and a main rotary shaft connected to a driving rotor in the hydraulically driven rotor type water turbine forms the driving output shaft to be connected to a main rotary shaft in the foam rotor pump. The hydraulically driven rotor type water turbine and the foam rotor pump are designed into a whole, the cost is low, the structure is compact, the size is small, a mounting space is greatly reduced, and the system will consume a lower firefighting water pressure due to high volume efficiency.

Description

technical field [0001] The invention relates to a foam proportional mixing device. In particular, it relates to a rotor mechanically pumped foam proportional mixing device, which is driven by fire-fighting water to rotate a water turbine, drives a foam rotor pump to operate, pressurizes the foam liquid and mixes it with the fire-fighting water that drives the water turbine to form a fire-fighting foam liquid. Background technique [0002] Foam proportional mixing device is an indispensable device in fire fighting facilities. At present, the foam proportional mixing device mainly has the following four generations of products: [0003] The first generation product: a foam liquid proportional mixing device in the form of negative pressure. Negative pressure is generated when the fire-fighting water passes through the proportional mixer, and the foam liquid is inhaled and mixed with the fire-fighting water to form a foam mixture. The foam proportional mixing device has the ad...
