Description

A kind of fire demand water pump
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 Being equipped with base, the left side of described base is provided with the pump housing, and the bottom of the described pump housing is provided with the pipe plug that discharges water.
The described pump housing be provided centrally with impeller, the right side of the described pump housing is provided with pump cover, described pump cover and the described pump housing Between be placed with sealing ring.
The centre bore being provided centrally with horizontal structure of the described pump housing, the right side of the described pump housing is provided with motor, described electricity Machine is provided with motor shaft.
Described motor shaft is installed in described centre bore, and described impeller is received on described motor shaft with being bonded, described impeller Right-hand member be provided with impeller nut.
It is provided with pad between described impeller and described impeller nut, arranges organic between described motor shaft and described pump cover Tool seals, and described mechanical seal is thread seal, and described pump cover is additionally provided with vent valve.
As preferably, between described pump cover and described motor, be provided with protective cover, described protective cover and described motor shaft it Between have retaining ring.
As preferably, described impeller is five chip semi-open-type impellers, and the material of described impeller is bronze.
Compared with prior art, usefulness of the present invention is: be provided with motor, impeller key and impeller nut is fixed On motor, so that motor energy impeller rotates, and on pump cover, it is provided with vent valve, it is thus possible to made by the pump housing The gas produced during with is drained, and present configuration is simple, and easy to operate, cost is relatively low.
