Description
Technical field
It the utility model is related 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, pumps in long-play, can be slow due to the heat transfer of pump shaft
Lubricating oil in bearing housing is heated, so as to cause lubricating oil to fail, and then causes bearing failure, damages pump.The prior art
In typically use air-cooled and water cooling mode to bearing housing cool down.Wind turbine is typically installed in air-cooled cooling vertically, and cooling is not
Uniformly；Water cooling needs to install axle sleeve and additionally mounted cycling mechanism, structure are relative complex.
The content of the invention
The purpose of this utility model is to provide a kind of effectively barrier pump housing heat, using being lubricated in air-cooled while bearing housing
Oily self-loopa, to reach cooling uniformly from flowing forced air cooling high-temperature pump.
To achieve the above objectives, the technical solution that the utility model is taken is：
From flowing forced air cooling high-temperature pump, including the pump housing, bearing housing is installed at the top of the pump housing, is equipped with down between bearing housing and the pump housing
Vented cavity, bearing housing top are provided with vented cavity, and shaft is from after the pump housing sequentially passes through lower vented cavity, bearing housing and upper vented cavity
It is connected with driving motor, blade is separately installed with upper and lower vented cavity, two blade water conservancy diversion directions are identical, the side of upper and lower vented cavity
Side is equipped with ventilating opening, it is characterised in that fixing sleeve is equipped with self-loopa bearing holder (housing, cover) on the main shaft of the bearing housing inner bearing, follows certainly
Annulate shaft bearing sleeve outer sheath has self-loopa overcoat, and bearing inner race fixes the both ends for being placed on self-loopa bearing holder (housing, cover), and self-loopa overcoat is located at
Between two bearings, fixed, the inner wall of self-loopa overcoat or followed certainly by floor between the outer wall and bearing chamber interior wall of self-loopa overcoat
Single head or multi-head spiral groove are machined with annulate shaft bearing sleeve outer wall.
Further, the outer wall of bearing housing is equipped with the axial heat sink of a circle.
Further, it is lower underfill in thermal insulation layer, or lower vented cavity is installed between vented cavity and the pump housing to have 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 shaft, and this programme passes through three
The cooling being implemented in combination with to bearing housing lubricating oil of kind mode.
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 exterior suction cold wind via the air passage that upper ventilation cavity wall is formed to bearing
Case realizes wind cooling temperature lowering, and bearing housing external belt heat sink, improves cooling effect.Lower vented cavity intra vane rotates to form negative pressure, adds
The flowing of wind in speed in vented cavity and Accelerating Removal, play the effect of strong wind cooling；
Finally, using the principle of screw pump, by the cooperation of self-loopa bearing holder (housing, cover) and self-loopa overcoat, the viscous of oil is utilized
Property, realize up and down flowing of the lubricating oil in bearing housing so that obtain deep fat and the hot friendship of cold oil progress close to heat sink by paraxial
Change so that the inside lubricating oil temperature of bearing is uniform, 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 structure diagram of the utility model.
In figure:The pump housing 1, lower vented cavity, bearing housing 3, upper vented cavity 4, thermal insulation layer 5, shaft 6, blade 7, heat sink 8, from
Circulate bearing holder (housing, cover) 9, self-loopa overcoat 10, helicla flute 11.
Embodiment
Specific embodiment of the present utility model is further described below in conjunction with attached 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, axis from bottom to top
Case 3 and upper vented cavity 4 are held, is 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 thermal insulation layer 5 is filled in bottom in lower vented cavity 2, prevents cabinet exterior heat from conducting to bearing housing.Shaft 6 from the pump housing successively
It is connected after through lower vented cavity 2, bearing housing 3 and upper vented cavity 4 with driving motor, connection mode can take shaft coupling or belt
Deng；The side of upper and lower vented cavity is equipped with ventilating opening, and blade 7 is separately installed with upper and lower vented cavity, and blade 7 is fixedly installed in
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 equipped with a circle axis
To heat sink 8, it is upper ventilation 4 chambers suction cold air, through cavity inner wall formed air passage blow over heat sink 8, after taking away heat, under
Vented cavity 2 discharges the hot-air after heat exchange.
Fixing sleeve is equipped with self-loopa bearing holder (housing, cover) 9 on the main shaft of 3 inner bearing of bearing housing, 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 being fixed by floor or monoblock cast, leave passage between 3 inner wall of 10 outer wall of self-loopa overcoat and bearing housing,
