Description
Technical field
The present invention relates to a kind of pump, and in particular to a kind of from flowing forced air cooling high-temperature pump.
Background technology
High-temperature pump is primarily adapted for use in conveying high-temperature medium, and pump, can be slow due to the heat transfer of pump shaft in long-play
Lubricating oil in bearing housing is heated, so as to cause lubricating oil to fail, and then causes bearing failure, damages pump.Prior art
In typically use air-cooled and water cooling mode to bearing housing cool down.Blower fan is typically installed in air-cooled cooling vertically, and cooling is not
Uniformly；Water cooling needs mounting sleeve and additionally mounted cycling mechanism, structure are relative complex.
The content of the invention
Pump housing heat is effectively obstructed it is an object of the invention to provide a kind of, using lubricating oil in air-cooled while bearing housing certainly
Circulation, to reach cooling uniformly from flowing forced air cooling high-temperature pump.
To achieve the above objectives, the technical scheme taken of the present invention is：
From flowing forced air cooling high-temperature pump, including the pump housing, bearing housing is installed at the top of the pump housing, lower ventilation is provided between bearing housing and the pump housing
Chamber, is provided with vented cavity at the top of bearing housing, rotating shaft from the pump housing sequentially pass through lower vented cavity, bearing housing and upper vented cavity after with drive
Motor connection is moved, is separately installed with blade in upper and lower vented cavity, two blade water conservancy diversion directions are identical, on the side of upper and lower vented cavity
Provided with ventilating opening, it is characterised in that fixed cover is equipped with self-loopa bearing holder (housing, cover), self-loopa axle on the main shaft of the bearing housing inner bearing
Self-loopa overcoat is cased with the outside of bearing sleeve, bearing inner race fixes the both ends for being placed on self-loopa bearing holder (housing, cover), and self-loopa overcoat is located at two axles
Between holding, fixed between the outer wall and bearing chamber interior wall of self-loopa overcoat by floor, the inwall or self-loopa axle of self-loopa overcoat
Single head or multi-head spiral groove are machined with bearing sleeve outer wall.
Further, the outer wall of bearing housing is provided with the fin of a circle axial direction.
Further, it is lower that thermal insulation layer is installed between vented cavity and the pump housing, or lower vented cavity inner bottom part is filled with thermal insulation layer.
Yet further, the section of the helicla flute is parallelogram or trapezoidal.
The technical program has the beneficial effect that：
The origin of heat of high temperature pump bearing box is mainly the heat transfer generation of pump housing shell and rotating shaft, and this programme passes through three kinds of sides
The cooling being implemented in combination with to bearing housing lubricating oil of formula.
First, infiltration of the high temperature to bearing housing is prevented by thermal insulation layer, avoids the external heat transfer to bearing housing；
Secondly, it is oriented to by upper vented cavity from the air channel that outside suction cold wind is formed via upper ventilation cavity wall real to bearing housing
Existing wind cooling temperature lowering, bearing housing external belt fin, improves cooling effect.Lower vented cavity intra vane rotates to form negative pressure, in acceleration
The flowing of wind in vented cavity and Accelerating Removal, play the effect of strong wind cooling；
Finally, it is real using the viscosity of oil by the cooperation of self-loopa bearing holder (housing, cover) and self-loopa overcoat using the principle of screw pump
Existing up and down flowing of the lubricating oil in bearing housing so that obtain deep fat and the cold oil progress heat exchange close to fin close to axle, make
It is uniform to obtain the inside lubricating oil temperature of bearing, realizes overall cooling.
The good cooling results of the technical program, improve the service life of bearing housing.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
In figure:The pump housing 1, lower vented cavity, bearing housing 3, upper vented cavity 4, thermal insulation layer 5, rotating shaft 6, blade 7, fin 8, from
Circulate bearing holder (housing, cover) 9, self-loopa overcoat 10, helicla flute 11.
Embodiment
The embodiment of the present invention is further described below in conjunction with accompanying drawing：
From flowing forced air cooling high-temperature pump, including the pump housing 1, the top of the pump housing 1 is sequentially installed with lower vented cavity 2, bearing housing 3 from bottom to top
With upper vented cavity 4, installed in a manner of flange face and bolt.Thermal insulation layer 5 is installed between lower vented cavity 2 and the pump housing 1, or every
Thermosphere 5 is filled in the lower inner bottom part of vented cavity 2, prevents cabinet exterior heat from conducting to bearing housing.Rotating shaft 6 sequentially passes through down from the pump housing
It is connected after vented cavity 2, bearing housing 3 and upper vented cavity 4 with motor, connected mode can take shaft coupling or belt etc.；Upper,
The side of lower vented cavity is provided with ventilating opening, and blade 7 is separately installed with upper and lower vented cavity, and blade 7 is fixedly installed in rotating shaft 6,
Two blade water conservancy diversion directions are identical, and suction is blown down in formation, accelerate air circulation.The outer wall of bearing housing 3 is provided with dissipating for a circle axial direction
Backing 8, upper ventilation 4 chambers suction cold air, fin 8 is blown in the air channel formed through cavity inner wall, after taking away heat, lower vented cavity
Hot-air after 2 discharge heat exchanges.
Fixed cover is equipped with self-loopa bearing holder (housing, cover) 9 on the main shaft of the inner bearing of bearing housing 3, and the outside of self-loopa bearing holder (housing, cover) 9 is cased with certainly
Overcoat 10 is circulated, bearing inner race fixes the both ends for being placed on self-loopa bearing holder (housing, cover) 9, and self-loopa overcoat 10 is between two bearings, certainly
Circulation overcoat 10 with fixed by floor or monoblock cast, leave passage between the outer wall of self-loopa overcoat 10 and the inwall of bearing housing 3,
