Description
Technical field
The invention belongs to fire fighting device technical fields, and in particular to a kind of fire-fighting pump configuration of used in fire-fighting.
Background technology
As is known in the industry, by the function and usage of fire fighting truck classification have fire fighting vehicle, airport crash fire vehicle, special apparatus,
Elevating fire truck and auxiliary fire vehicle, etc..Fire fighting vehicle has pumper apparatus, triple, foam truck and does
Powder fire fighting truck etc.；Airport crash fire vehicle is exclusively used in processing aircraft fire accident, can spray fire extinguishing agent under steam, including airport rescues
Help guide's fire fighting truck and rescue and relief work fire fighting truck etc.；Special apparatus has command and communication fire vehicle, Lighting tower fire vehicle, speedily carries out rescue work and rescue
Calamity fire fighting truck, reconnaissance fire vehicle, propaganda fire vehicle and smoke exhauster truck etc.；Elevating fire truck has Elevating platform fire truck, lifts
Height injection fire fighting truck and hook and ladder etc.；Auxiliary fire vehicle has water tanker, foam truck and rescue fire fighting truck etc.
Deng.
It is no lack of the technical information for being seen in fire fighting truck, such as CN101274127B in disclosed Chinese patent literature（It is a kind of micro-
Type fire fighting truck）、CN101766875B（Multipurpose high-pressure water mist fire truck）、CN101757753B（With the light of spray gun combination spray
Type high-pressure water mist fire truck）、CN103623528B（A kind of urban turbojet fire vehicle）、CN103958004B（Suitable for high level
With the fire fighting truck of high-rise building fire attack）、CN103599609A（Superabsorbent fire extinguishing pumper apparatus deeply）、CN103751931B
（Fire hose is laid with fire fighting truck automatically）And CN103935285B（A kind of two way rail dual-purpose multifunctional emergency rescue firefighting
Vehicle）, etc..
And then as is known in the industry, it is logical to be related to the typical such as pumper apparatus of fire fighting truck that firing-fighting medium is water or similar liquids
Often equipped with fire pump, which is also referred to as booster pump（It is the same below）.Equally it is no lack of in disclosed Chinese patent literature and is seen in
The technical information of fire pump, such as CN205401147U（A kind of controllable outlet pressure fire pump）、CN205446089U（A kind of stream
Fire pump is adjusted in amount）、CN202876181U（Fire pump suction pipe road system and fire fighting truck）And CN101216045A（It can be certainly
The fire-fighting truck water pump of dynamic release）, etc..By the reading of the aforementioned patent literature to being not limited to enumerate：Fire pump
Water inlet and water outlet be located at the pump housing both sides or water inlet in the side of the pump housing, and water outlet is in the pump housing
Top.The fire pump of this structure generates different application demands since water inlet with water outlet is non-interchangeable
It influences.
It is more as is known in the industry, when fire fighting truck is furnished with fire monitor（That is " water cannon "）When, it is located at top（It is generally located in roof）
The water inlet of fire monitor and the water outlet of fire pump between there are larger differences in height；When the fire-fighting with automatic water-leading function
Che Shi, primer pump（It fetches water from Ha Noi usually using floating ship pump）Water outlet and the water inlet of fire pump between there are larger height
The water outlet and hydraulic giant of degree difference and fire pump are with equally existing certain difference in height between water lines.The former example is such as
CN201578783U（Cross-country water cannon fire-fighting truck）、CN202459913U（There are two arm top fire water monitor to elevate injection fire-fighting for band
Vehicle）、CN106492382A（The mounting structure and high lifting kind fire fighting truck of water cannon）And CN106730523A（Fire water monitor motion control
System and fire fighting truck）, etc.；The example of the latter such as CN107050707A（Automatic water-leading fire fighting truck）、CN106693247A（Have
The automatic water-leading fire fighting truck of crane arm revolute function）、CN106593892A（The semi-submersible type of automatic water-leading used in fire-fighting floats ship pump knot
Structure）、CN106730540A（Water fetching device）And CN106730529A（Hose laying fire fighting truck with water intaking function）, etc..
The water inlet for being not limited to the water cannon of the aforementioned patent enumerated need to be by the water outlet of interminable pipeline and fire pump
Between be attached, interminable pipeline and fire-fighting need to be used by being equally not limited to the water outlet of the primer pump of the aforementioned patent enumerated
It is attached between the water inlet of pump and the length realization that need to increase hydraulic giant water lines is connect with the water outlet of fire pump.No
By be the pipeline being connect with the water outlet of fire pump or the pipeline being connect with the water inlet of fire pump it is longer will produce it is following
Shortcoming：First, pipeline private space is big, it is unfavorable for embodying compact effect；Second is that pipeline exists and other component phases on fire fighting truck
The anxiety of mutual interference；Third, the power attenuation of fire pump is big.
For above-mentioned prior art situation, the applicant has made positive and beneficial exploration and design, forms down finally
The technical solution that face will the be introduced and equipment test center in the case where taking secrecy provision in the applicant is simulated
Experiment, is as a result proved to be practicable.
