Description
Technical field
The utility model is related to a kind of fixing device for centrifugal pump, and especially a kind of simple and reliable for structure, design is skilful
The radially-directed bracing means for being applied to vertical volute centrifugal pump that is wonderful, can effectively increasing the service life.
Background technology
Existing vertical volute centrifugal pump, its water wheels drive shaft is fixed by big axle and packing differential
, when running up, big axle and packing differential are subject to very big radial stress, easily release, meanwhile, packing itself is without single
Only cooling device, easy high temperature, causes the lost of life.
Utility model content
To solve the above problems, the utility model provide it is a kind of it is simple and reliable for structure, design it is ingenious, can effectively extend and make
With the radially-directed bracing means for being applied to vertical volute centrifugal pump in life-span.
Realize the radially-directed bracing means for being applied to vertical volute centrifugal pump of the utility model purpose, including big axle
It is cylindrical with the water wheels drive shaft for driving water wheels fixed by big shaft compression, the big axle and water wheels driving shaft connection place
Week, stay bolt was fixed with the packing differential for compressing packing, the big axle of fixation and water wheels drive shaft, the side of the packing differential
Wall is provided with the packing_seal tank of interior Sheng packing_seal water.
The bottom of the packing differential, the excircle of water wheels drive shaft are cased with pump cover, bottom, the water wheels of the upper pump cover
The excircle of drive shaft is cased with water wheels driving bearing cover, and lag bolt is passed through between the upper pump cover and water wheels driving bearing cover
It is connected.
Space inner sleeve water lubrication bearing between the inner periphery of the upper pump cover and the excircle of water wheels drive shaft, it is described
Water lubriucated bearing is entered by the water lubriucated bearing cooling water in the water lubriucated bearing sealed cistern in the upper pump cover being disposed above
Row cooling.
The radially-directed bracing means for being applied to vertical volute centrifugal pump described in this patent, by setting outside packing
Packing differential is put, and the side wall in packing differential arranges packing_seal water so that the better tightness of packing, while packing_seal
Water may also operate as to the effect of packing cooling, prevent its from overheated causing the lost of life；By in upper pump cover and water wheels drive shaft
Between water lubriucated bearing is set, reduce the stress that packing differential is directly acted on when water wheels drive shaft rotates at a high speed, meanwhile, water
Lubrication bearing coolant can be cooled down to water lubriucated bearing, prevent its from overheated causing the lost of life.
This patent overall structure is simple and reliable, designs ingenious, effectively reduces abrasion when each part runs, and can be effective
The temperature of each part is reduced, extends the service life of whole machine.
Description of the drawings
Fig. 1 is the structural representation of the radially-directed bracing means for being applied to vertical volute centrifugal pump of the present utility model
Specific embodiment
As shown in figure 1, the radially-directed bracing means for being applied to vertical volute centrifugal pump of the present utility model, including it is big
Axle 4 and the water wheels drive shaft 9 for driving water wheels 8 being fixed by big axle 4, the big axle 4 and water wheels drive shaft 9 are connected
The excircle stay bolt 10 at place is fixed with the packing differential 3 for compressing packing 11, the big axle 4 of fixation and water wheels drive shaft 9, institute

The bottom of the packing differential 3, the excircle of water wheels drive shaft 9 are cased with pump cover 6, the bottom of the upper pump cover 6,
The excircle of water wheels drive shaft 9 is cased with water wheels driving bearing cover 7, leads between the upper pump cover 6 and water wheels driving bearing cover 7
Cross lag bolt 12 to be connected.
Space inner sleeve water lubrication bearing 1 between the inner periphery of the upper pump cover 6 and the excircle of water wheels drive shaft 9,
The water lubriucated bearing 1 is cold by the water lubriucated bearing in the water lubriucated bearing sealed cistern 5 in the upper pump cover 6 being disposed above
But water is cooled down.
The radially-directed bracing means for being applied to vertical volute centrifugal pump described in this patent, by outside packing 11
Packing differential 3 is set, and the side wall in packing differential 3 arranges packing_seal water so that the better tightness of packing 11, while disk
Root sealing water may also operate as, to the effect of the cooling of packing 11, preventing its from overheated causing the lost of life；By in upper pump cover 6 and water
Water lubriucated bearing 1 is set between wheel drive shaft 8, is reduced when water wheels drive shaft 8 rotates at a high speed and is directly acted on packing differential 3
Stress, meanwhile, water lubriucated bearing coolant can be cooled down to water lubriucated bearing 1, prevent its from overheated causing the lost of life.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, under the premise of without departing from the utility model design spirit, this area ordinary skill technical staff couple
Various modifications and improvement that technical solutions of the utility model are made, all should fall into the guarantor that claims of the present utility model determine
In the range of shield.
