Description
Technical field
The present invention relates to the Corrosionproof pump used in liquid that length under field centrifugal pump production field more particularly to liquid reaches 4 ~ 5 meters.
Background technique
Depth generally only has 1.8 ~ 2 meters under the liquid of commercially available Corrosionproof pump used in liquid, is unable to reach non-Corrosionproof pump used in liquid on the market
Liquid under 4 ~ 5 meters of length.Above-mentioned reality can not meet user and require to be promoted suction and conveying underground pit level in the corruption of 3 ~ 4 meters of depths
The demand of corrosion liquid.
The reason of generating the above results is as follows: such as Fig. 1, submerged pump generally uses receded disk impeller 1, and receded disk impeller passes through
Centrifugal action generates Fluid pressure, suction and conveying liquid or slurry, therefore has very big radial thrust on impeller circumferential surface, and this
Radial thrust is unbalanced in the surrounding of impeller, and the Fluid pressure for pumping out liquid oral area 2 is greater than the Fluid pressure of the other side, this just makes this
Kind pressure becomes to push monomer long axis 3 to the inclined lateral force in liquid outlet side, makes the amesiality operation of monomer long axis, this lateral
Thrust is conducted to the bearing portion on top, and then damages the bearing 4 of partial monosomy long axis on liquid.
Such as a kind of revolving speed is 1450 revs/min, flow 100m3/h, the submerged pump that lift is 30 meters, impeller portion acts on monomer
The lateral force of long axis agitates bearing again using monomer long axis as lever up to 200 ~ 300kg, this lateral thrust, and monomer long axis is longer,
Lever force is bigger, and bearing receiving eccentricity pressure is bigger, and bearing damage is faster, this is the common fault of centrifugal long shaft submerged pump.
In order to overcome above-mentioned deficiency, people are combined when making common non-Corrosionproof pump used in liquid using multisection type monomer long axis,
And radial support portion is added at each combination section.Such as the methods of sliding bearing is set to eliminate monomer long axis lateral force to bearing
Influence, in this way to non-corrosion-resistant long axis centrifugation submerged pump be effectively because each supporting part does not need to prevent liquid
The corrosion of body, this is also the common method of conventional submerged pump manufacture of the depth between 3 ~ 5 meters under liquid.But this method is to long axis
Corrosionproof pump used in liquid is but not suitable for, and main problem is that the anti-corrosion wrapping layer of the monomer long axis engaging portion of piecewise combination is difficult, nothing
The connector of method solution segmentation monomer long axis engaging portion and the Anticorrosion of supporting part, therefore long axis Corrosionproof pump used in liquid (3 ~ 4 meters)
Core manufacturing technology can not still solve.
If using single branch long axis, although monomer long axis anti-corrosion protection problem can solve, due to the lateral force of impeller,
It can cause the bearing damage on liquid top, pump service life is not grown, and general 2 ~ 4 months bearings will damage;If combined with multistage
Axis bonus point section supporting structure, then the Anticorrosion of the monomer long axis engaging portion of part is difficult to solve under liquid, the anti-corrosion of engaging portion
Difficulty is larger, and cost is also higher, can not carry out good industrial application.
In order to solve the problems, such as that the bearing of anti-corrosion long shaft submerged pump often damages, those skilled in the art, which use, to be increased up and down
The diameter of spacing and monomer long axis between bearing achievees the purpose that protect bearing so that monomer long axis anti-twisting property be made to increase;
Also there are those skilled in the art to take and increase pump housing spiral case diameter, and then increase pump chamber runner, the pressure of relative reduction impeller periphery
Difference controls the damage of pump shaft.But the effect of this scheme not only monomer long axis lateral force resistance is poor, but also will increase the system of the pump housing
Make cost, while reducing the efficiency of pump.In this way the problem that is that not only Corrosionproof pump used in liquid manufacturing cost is significantly
Increase, and will cause submerged pump top heavy, gravity center instability, installation inconvenience, is also easy to produce the defects of safety accident.
Therefore the manufacturing technology of long axis Corrosionproof pump used in liquid in the industry, always exists problem, including the applicant, production
Nearly 30 years Corrosionproof pump used in liquid, are not solved effectively yet by total manufacture nearly 100,000.Industry depth pond, deep groove etching
The suction and conveying of property liquid is still optional without ideal pump, and the above problem has much room for improvement.
Summary of the invention
The object of the present invention is to provide a kind of monomer long axis, antiseptic property is good, pump chamber can be greatly reduced to axis laterally pushing away
Power, the problem of preventing the leverage due to long axis from leading to the bearing reduced service life on liquid top, low manufacture cost, conveying effect
Single long axis Corrosionproof pump used in liquid that rate improves.
Purpose to realize the present invention improves following technical scheme: a kind of list long axis Corrosionproof pump used in liquid, is vertical structure,
Including driving motor, with the coaxially connected monomer long axis of driving motor main shaft, the sectional shelf-unit for installing monomer long axis and
The pump housing of end, monomer long axis lower end are protruded into the pump housing, are offered on the pump housing into axis hole, liquid outlet, suction inlet and connection three
The pump chamber of person is coaxially disposed into axis hole and suction inlet, and pump housing liquid outlet connects outlet tube, it is characterised in that in the pump housing suction inlet with
Monomer long axis is coaxially arranged with cylindrical section, and cylindrical section and the pump housing are seperated or integral structure, monomer long axis lower end be equipped with to
A few turbine, at least one section of turbine is located in cylindrical section.
