For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
A kind of chopper type centrifugal submersible pumps, including the pump housing, base, the motor component that is arranged in the pump housing with
And impeller；Described impeller is unshrouded impeller, integrally formed with dynamic chopping disk on described impeller, the described pump housing
Bottom is provided with fixing chopping disk, leaves gap, described fixing chopping disk between described fixing chopping disk and impeller
It is provided with cutting slot；
Described centrifugal submersible pumps also includes that an adjusting means, described adjusting means are used for regulating fixing chopping disk
And the size in gap between impeller, described adjusting means is the regulation spiral shell being fixed on the pump housing by fixing chopping disk
Nail.
In an embodiment of the present utility model, described cutting slot is along the fixing uniform cloth of chopping disk length direction
Put.
In an embodiment of the present utility model, described cutting slot is spiral cutting groove.
In an embodiment of the present utility model, described gap is 1-2cm.
By technique scheme, the beneficial effects of the utility model are:
1, impeller uses unshrouded impeller design, and two blades are uniform, and dynamic chopping disk and Impeller Design are an entirety,
Simple in construction, casts and easy to assembly, quick；
2, between impeller and fixing chopping disk, bits groove is scraped in design, can effectively by impeller and fixing chopping disk it
Between the chip of thin and flexible clamp-oned strike off, be prevented effectively from motor overpower and stall；
3, unique understructure design, can conveniently adjust impeller by regulation screw and cut with fixing
Cut the gap between dish, make pump performance remain at efficient state, and without tearing pump open when adjusting, it is not necessary to specially
Use instrument.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below by right
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that below,
Accompanying drawing in description is only embodiments more of the present utility model, comes for those of ordinary skill in the art
Say, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is existing chopper type centrifugal submersible pumps structural representation；
Fig. 2 is this utility model chopper type centrifugal submersible pumps structural representation；
Numeral and the corresponding component title represented by letter in figure:
10, the pump housing 20, base 30, motor component 40, impeller 50, dynamic chopping disk 60, solid
Determine chopping disk 61, cutting slot 70, gap 80, regulation screw.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be readily apparent from effect
Understand, below in conjunction with being specifically illustrating, this utility model is expanded on further.
Shown in Figure 2, the utility model discloses a kind of chopper type centrifugal submersible pumps, including the pump housing 10,
Base 20, the motor component 30 being arranged in the pump housing and impeller 40；Impeller 40 is unshrouded impeller, two
Blade is uniform, and integrally formed with dynamic chopping disk 50 on impeller 40, integral structure has simple in construction, casting
The advantage such as making and easy to assembly, quick, dynamic chopping disk 50 takes into account the effect of stirring when designing, during pump operation
Can be stirred being deposited in the dirt bottom cesspool, enable dirt to enter the chopping of pump to greatest extent
Chamber；The bottom of the pump housing 10 is provided with fixing chopping disk 60, fixes between leaving between chopping disk 60 and impeller 40
Gap 70, gap is 1-2cm, and it is also dependent on being actually needed setting, is not added with repeating herein；Fixing chopping disk
60 are provided with cutting slot 61, and cutting slot 61 is evenly arranged along fixing chopping disk length direction, cutting slot 61
For spiral cutting groove, the cutting slot of this structure has the advantage of good cutting effect；The design of cutting slot can be effective
The chip of the thin and flexible clamp-oned between impeller and fixing chopping disk gap is struck off by ground, it is to avoid motor surpasses merit
Rate and stall.
This utility model impeller 40 and fixing chopping disk 60 use corrosion-resistant material to make, and through special
Process, it is ensured that the cutting edge on impeller and fixing chopping disk has enough strength and stiffness, the most corrosion-resistant,
The most wear-resistant, can keep sharp for a long time.
This utility model centrifugal submersible pumps also includes an adjusting means, and adjusting means is used for regulating fixing cutting
