Abstract

The invention provides a rotor mechanically-pumping type foam proportionally-mixing device. The rotor mechanically-pumping type foam proportionally-mixing device comprises a hydraulic drive rotor type water turbine with fire-fighting water as power, a foam gear pump connected with a drive output shaft of the hydraulic drive rotor type water turbine through a middle bearing mechanism and a fire-fighting mixed liquid guide-out mechanism connected with a water outlet of the hydraulic drive rotor type water turbine and a liquid outlet of the foam gear pump and used for outputting fire-fighting mixed liquid. The hydraulic drive rotor type water turbine is of a driving-rotor and driven-rotor structure, and a constant gap is set between two rotors forming the driving-rotor and driven-rotor structure. The foam gear pump is of a driving and driven double-gear structure. A main rotating shaft connected with the driving rotor in the hydraulic drive rotor type water turbine forms a drive output shaft connected with a main rotating shaft in the foam gear pump. According to the rotor mechanically-pumping type foam proportionally-mixing device, the hydraulic drive rotor type water turbine and a foam rotor pump are designed into a whole, the cost is low, the structure is compact, the size is small, the mounting space is reduced greatly, and the lesser fire-fighting water pressure is consumed by a system due to the fact that volume efficiency is high.

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...
