Abstract
The utility model discloses a kind of box axial-flow type firefighting fan, the box axial-flow type firefighting fan is by Type B three phase electric machine, casing, deep bead and draught fan impeller are constituted, Type B three phase electric machine is positioned on casing side position on the upper side, motor shaft is in box house, draught fan impeller is on motor shaft, open round-meshed deep bead and casing is divided into two isopyknic chamber, deep bead is coplanar with draught fan impeller, the Circularhole diameter of deep bead is more than the diameter of draught fan impeller, its center of circular hole is concentric with machine shaft, air inlet is in casing board motor body side, air outlet is on the relative box plate of air inlet and the two size is identical.The motor of existing axial-flow type firefighting fan is all in the gas for being conveyed; need to be protected with shell and ventilating and cooling; it occupies partial ventilation section; reduce effective discharge; when firefighting fan works; high-temperature gas can make motor heat up, and shorten firefighting fan service life, and the utility model then solves the problems referred to above.
Description
Technical field
The utility model is related to a kind of fluid mechanical device, more particularly to a kind of box axial-flow type firefighting fan.
Background technology
The motor of existing axial-flow type firefighting fan is needed to be protected with iron-clad and leads to all in the gas for being conveyed
Air cooling, it occupy a part of ventilation section, reduce effective discharge, and when firefighting fan works, high-temperature gas can make motor
Heat up, so as to shorten firefighting fan service life.
Utility model content
The purpose of this utility model is to increase blower fan available ventilation area, reduces motor and heats up, and extending firefighting fan makes
Use the life-span.
In order to solve the above problems, using following scheme：
Box axial-flow type firefighting fan, is made up of Type B three phase electric machine, casing, deep bead and draught fan impeller, Type B three-phase electricity
Machine is in box house positioned on the outside side of casing position on the upper side, motor shaft, and draught fan impeller has circular hole on motor shaft
Deep bead casing is divided into two isopyknic chamber, deep bead is coplanar with draught fan impeller, and the Circularhole diameter of deep bead is bigger
In the diameter of draught fan impeller, its center of circular hole is concentric with machine shaft, and below casing board motor body, air outlet is entering air inlet
On the relative box plate in air port and the two size is identical.
Technique scheme is taken, is had the effect that：
The utility model is a kind of box axial-flow type firefighting fan, and it increased blower fan available ventilation area, effectively
Reduce motor to heat up, extend firefighting fan service life.
