Abstract

The invention discloses a gear machine pumping-in type foam proportional mixing device. The gear machine pumping-in type foam proportional mixing device includes a hydraulic driving gear-type water turbine, a foam rotor pump which is connected with a driving output shaft of the hydraulic driving gear-type water turbine through an intermediate bearing mechanism, and a fire protection mixed liquor leading-out mechanism which is connected with a water outlet of the hydraulic driving gear-type water turbine and a liquor outlet of the foam rotor pump. The hydraulic driving gear-type water turbine is of a master-slave double-gear structure, and a constant gap is set between two gears constituting the master-slave double-gear structure. The foam rotor pump is of a master-slave double-rotor structure, and a constant gap is set between two rotors constituting the master-slave double-rotor structure. A main rotating shaft connected with a driving gear in the hydraulic driving gear-type water turbine forms the driving output shaft to be connected with a main rotating shaft in the foam rotor pump. According to the gear machine pumping-in type foam proportional mixing device, the hydraulic driving gear-type water turbine and the foam rotor pump are designed into a whole, cost is low, the structure is compact, the size is small, using is convenient, and due to the high volume efficiency, the system can consume lower fire protection water pressure.

Description

technical field [0001] The invention relates to a foam proportional mixing device. In particular, it relates to a gear-mechanical pump-in foam proportional mixing device, which is driven by fire-fighting water to rotate a water turbine and drive a foam gear pump to run. 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 advantages of simple structure and low cost. Foam can also be added, but the disadvantage is that the foam mixing ratio is not precise and stab...
