Detailed description of the invention
Below in conjunction with accompanying drawing the technical solution of the utility model done and the most clearly and completely describe.
As shown in Figure 1: a kind of axial force automatic balancing multistage pump that the present embodiment provides, including urceolus 1 be arranged at urceolus 1
Interior inner core, described inner core is divided into inner core 2 and lower inner core 3, is provided with upper runner 4 between described upper inner core 2 and urceolus 1,
It is provided with lower flow channel 5 between described lower inner core 3 and urceolus 1, is provided with, in lower inner core 3, the impeller that quantity is identical at upper inner core 2
6, the bottom of described urceolus 1 is provided with water inlet 7 and outlet 8.
The impeller inlet 201 being positioned in inner core 2 is connected with upper runner 4 upper, is positioned at the impeller outlet of inner core 2
202 under be connected with lower flow channel 5；The impeller inlet 301 being positioned in lower inner core 3 under be connected with water inlet 7,
The impeller outlet 302 being positioned in lower inner core 3 is connected with upper runner 4 upper；Described lower flow channel 5 is connected with outlet 8
Logical.That is, the impeller 6 being positioned at inner core 2 is reversely installed with the impeller 6 being positioned at lower inner core 3, thus makes forward axial
Power is offset with reverse axial force automatic balancing.
In order to be completely counterbalanced by axial force, it is positioned at impeller 6 quantity of inner core 2 and is positioned at impeller 6 quantity of lower inner core 3
Equal.
Leaving certain cavity between upper inner core 2 and lower inner core 3 as shunting section, be divided into two cavitys, one is impeller
Cavity between outlet 302 to upper runner 4, for low pressure chamber 9；One is the cavity between impeller outlet 202 to lower flow channel 5,
For high pressure chest 10.
In case of above inner core 2 is three with impeller 6 quantity in lower inner core 3, illustrate what the present embodiment provided
A kind of operation principle of axial force automatic balancing multistage pump:
As shown in Figure 2: liquid is the impeller inlet 301 of inner core 3 from water inlet 7 enters, sequentially pass through one stage impeller 601,
Discharge from impeller outlet 302 after the pressurization of sencond stage impeller 602 and three grades of impellers 603, enter impeller outlet 302 to upper runner 4
Between low pressure chamber 9 shunt after enter upper runner 4；Liquid enters the impeller inlet 201 of upper inner core 2 by upper runner 4,
Discharge from impeller outlet 202 after sequentially passing through the pressurization further of level Four impeller 604, Pyatyi impeller 605 and six grades of impellers 606,
The high pressure chest 10 entered between impeller outlet 202 to lower flow channel 5 shunts；From water outlet after final liquid entrance lower flow channel 5
Mouth 8 is discharged.
It is well known that: all impellers 6 are installed on impeller axle 11, and one end of impeller axle 11 is connected to by bearing
The bottom of multistage pump, the other end connects motor and is driven, and this is not described in detail by this utility model.
Water inlet 7 described in the utility model and outlet 8 can be arranged on the same axis, thus can be directly by this practicality
Novel connection is connected between pipeline the part as pipeline, can bring great convenience to in-site installation.
This utility model by multi-stage impeller is divided into two parts, the impeller intake of half part assemble down, second half portion
Point impeller inlet assemble upward so that forward axial force and reverse axial force can fully automated balance be offset, and impeller without
Need to use back of the body choma, make the axial arrangement size of pump substantially shorten, impeller axle intensity is strengthened, and diameter dimension is due to upper
The existence of runner and lower flow channel has increased slightly, so that pump body structure strength and stability is more preferable, fault rate is substantially reduced；
Further, since eliminate the parts such as back of the body choma so that leaking between pump stage and at least reduce half, work efficiency is improved, axle
Holding the life-span is greatly improved, and noise also will be minimized, practical.
Finally be necessary it is pointed out here that: the foregoing is only this utility model preferably detailed description of the invention, but this practicality
Novel protection domain is not limited thereto, the technology that any those familiar with the art discloses at this utility model
In the range of, the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.
