Description
Technical field
The utility model belongs to centrifugal pump field, in particular to a kind of novel standard-sized sheet Characteristics of Centrifugal Pulp Pump.
Background technique
In recent years from the point of view of paper industry development trend, existing pulp pump has been unable to meet wanting for paper industry development in China
It asks.The one kind of pulp pump as transh pump, when conveying the paper pulp containing solid particle, sealing and bearing are to be easiest to damage
Component.When serious pump can be unable to run the working performance that will affect pump once seal failure；And bearing once damages pump
Just it is unable to run.In transh pump, it is also to have a very large relationship greatly with axial force that bearing, which is easily damaged its reason,.When there is impurity
Into after seal chamber, there is larger shifting amount in pump shaft, leads to rotor part and stator friction, operates normally to influence pump, sternly
When weight pump can be able to not operate.In order to meet the market demand, product market competition ability is further increased, it is necessary to design one kind
Novel transh pump, it is desirable that axial force suffered by bearing can not only be reduced, and want that packing seal and mechanical seal can be overcome
Certain deficiencies, be particularly suitable for other difficult sealings with competent occasion, such as high speed, high temperature and sealing have aggressive
Or the medium for having suspended solid industry etc..
Summary of the invention
The purpose of this utility model is to solve above-mentioned technical problem, provides a kind of novel standard-sized sheet Characteristics of Centrifugal Pulp Pump.
In order to achieve the above technical purposes, reach above-mentioned technical requirements, the technology employed by the present utility model is
A kind of novel standard-sized sheet Characteristics of Centrifugal Pulp Pump, including the pump housing, pump shaft and mechanical seal；The pump shaft is mounted on the pump housing, and with
Mechanical seal cooperation is fixed；It is characterized by: the pump shaft front end is fixed with impeller, the impeller back by impeller nut
Face is provided with back blade；It is provided with accessory impeller on the left of the mechanical seal, the accessory impeller back side is provided with accessory lobes
Take turns back blade；Partition is provided between the impeller and accessory impeller, the partition back side is provided with partition back blade.
Preferred: the back blade and partition forms half-opened impeller, balances pump shaft axial force, enhances leakproofness
Energy.
Preferred: the partition back blade and accessory impeller forms half-opened impeller.
Preferred: the accessory impeller back blade and mechanical seal forms half-opened impeller.
The beneficial effects of the utility model are: a kind of novel standard-sized sheet Characteristics of Centrifugal Pulp Pump, compared with traditional structure: passing through back
The half-opened impeller of blade composition balances the axial force that pump shaft is subject to, and partition has blocked the rotation of liquid to improve envelope pressure energy
Power；The sub-impeller seal device for increasing setting, makes paper pulp generate outside centrifugal force, prevents paper pulp from flowing to mechanical seal, reduces
Pressure suffered by mechanical seal.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
1. the pump housing；2. pump shaft；3. mechanical seal；4. impeller nut；5. impeller；5-1. back blade；6. accessory impeller；6-
1. accessory impeller back blade；7. partition；7-1. partition back blade.
Specific embodiment
It is described further with reference to the accompanying drawing to originally practical；
In the accompanying drawings: a kind of novel standard-sized sheet Characteristics of Centrifugal Pulp Pump, including the pump housing 1, pump shaft 2 and mechanical seal 3；The pump
Axis 2 is mounted on the pump housing 1, and is cooperated with mechanical seal 3 and fixed；It is characterized by: 2 front end of pump shaft passes through impeller nut
4 are fixed with impeller 5, and 5 back side of impeller is provided with back blade 5-1；Accessory lobes are provided on the left of the mechanical seal 3
Wheel 6,6 back side of accessory impeller is provided with accessory impeller back blade 6-1；Partition is provided between the impeller 5 and accessory impeller 6
7,7 back side of partition is provided with partition back blade 7-1.
The back blade 5-1 and partition 7 forms half-opened impeller, reduces 2 axial force of pump shaft, enhances leakproofness
Energy.
The partition back blade 7-1 and accessory impeller 6 forms half-opened impeller.
The accessory impeller back blade 6-1 and mechanical seal 3 forms half-opened impeller.
When specific implementation:
This practical provisioned mechanical seal 3 is cooling without using pulp liquor, by the independent coolant inlet of outfit with
And cooling liquid outlet enters cooling pump shaft 2 in pump.Therefore pulp pump is provided with accessory impeller 6 and carrys out balancing axial thrust.Impeller 5 starts work
When making, accessory impeller 6 rotates together with pump shaft 3, and the liquid in accessory impeller 6 can also rotate together, and the liquid of rotation generates outside
Centrifugal force can not only withstand the liquid flowed at mechanical seal 3, reduce the pressure at mechanical seal 3；And paper can be prevented
Solid particle in slurry enters in the friction pair of mechanical seal 3.Back blade 5-1, partition back blade 7-1 and accessory impeller notopodium
The setting of piece 6-1 helps to reduce the pressure in pump chamber, avoids paper pulp from quickly rotating and generates a large amount of bubble concussion mechanical seals 3,
Protect the airtightness of mechanical seal 3.
Above-described embodiment is only intended to clearly illustrate description made by the utility model, and not to the limit of embodiment
It is fixed, to those of ordinary skill in the art, other various forms of variations can also be made on the basis of the above description
Or change, there is no necessity and possibility to exhaust all the enbodiments, and the obvious variation thus amplified out
Or it changes among still in the protection scope of the utility model.
