Description
Technical field:
The present invention relates to a kind of fire demand water pump, belong to pump technology field.
Background technology:
At present, the fire pump installed in built fire supply system, not only exist and be unsatisfactory for existing national regulation
The phenomenon of " fire water-supply and hydrant system technical specification " GB50974-2014 associated specifications, and exist many hidden
Suffering from, the fire pump used at engineering construction field at present, generally there is hump in its flow-lift performance curve, it may appear that water
Pump out the mouth of a river at the same pressure, there are two different flows.Now, fire pump surge runs, and does not reaches fire department
Fire extinguishing technological requirement, it addition, engineering construction field uses constant-pressure tangent fire pump in a large number, this pump capacity-lift performance
Curve is a horizontal line.In fire department fire extinguishing under battle conditions, the situation of super design discharge often occurs with water.Now, constant voltage is cut
Line fire water pump lift declines rapidly, and fire supply system lost efficacy rapidly.The performance curve of constant-pressure tangent fire pump does not has
Certain gradient, it is difficult to realize automatically controlling of fire supply system by pressure change.So industry needs a kind of novel knot
The water pump of structure, to solve problems faced in industry.
Summary of the invention:
The technical problem to be solved is: provide a kind of fire demand water pump, to solve problems faced in industry.
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions: a kind of fire demand water pump, if
