Description
Technical field
The present invention relates to fire-fighting equipment technical fields, more particularly to the fire fighting extinguisher with the hydraulic turbine and foam pump.
Background technology
Fixed froth installation is a kind of equipment with fire fighting function, in existing fixed froth installation, mostly
Directly being covered in using motor drive foam pump foam output liquid needs the place put out a fire to put out a fire.However in many fire
Calamity scene, circuit can not provide electric power support to generator at all, directly result in foam fire-fighting dress all by serious damage
Setting can not use, and fire-fighting work is directly restricted.
In existing, there is also a small number of fixed froth installations that foam pump work is driven using the hydraulic turbine, mainly pass through
Fire-fighting foams and water are mixed to form to required fire-fighting liquid, then fire-fighting liquid is ejected into the position for needing to put out a fire, the intensity of a fire is carried out
Covering is to achieve the purpose that fire extinguishing.In the above-mentioned fixed froth installation driven using the hydraulic turbine, using impact type
The hydraulic turbine needs the fire water for being passed through two-way high pressure simultaneously, first via high pressure fire fighting water to be used to that the hydraulic turbine to be driven to act on, to
Foam pump rotation is driven to take foam solution out of, the second road high pressure fire fighting water is then used to be used to put out a fire after mixing with foam solution.However the
High pressure fire fighting water all the way is therefore the kinetic energy that the kinetic energy of water is converted to the hydraulic turbine passes through water when driving hydraulic turbine acting
The discharge pressure of fire water after turbine is zero, it is impossible to be used in fire extinguishing can only exhaust and cause serious waste.
Invention content
The present invention is in view of the above-mentioned problems, propose the fire fighting extinguisher with the turbine type hydraulic turbine and foam pump.
The technical solution adopted by the present invention is as follows：A kind of fire fighting extinguisher with the hydraulic turbine and foam pump, including phase
The reaction turbine and foam pump of connection, the reaction turbine includes that body apparatus, water inlet pipe and tail water are taken over, described
