Abstract
A kind of separation-type screw for being suitable for pump class is the utility model is related to, includes screw body, the screw body includes screw sleeve and rotor, and the rotor embedded device is inside screw sleeve；The outer surface annular of the screw sleeve is provided with some helical blades, and the screw sleeve is equipped with spiral helicine mounting groove in the junction of corresponding helical blade；Helical blade positioned at the screw sleeve high order end and low order end is fixed in the mounting groove；The helical blade is arranged to semi-spiral shape, and helical blade described in adjacent two panels is respectively equipped with corresponding fixture block and card slot in junction.The utility model is not only simple in structure, and can reduce maintenance cost, avoids the waste of resource.
Description
Technical field
Machinery field is the utility model is related to, refers specifically to a kind of separation-type screw for being suitable for pump class.
Background technology
Screw pump is volume type rotor pump, it is changed by the volume of the annular seal space formed by screw rod and stator to suck
With discharge liquid.Screw pump by screw rod number be divided into single-screw (single screw) pump, it is double, three and five-screw pump.The characteristics of screw pump is flow
Steadily, pressure fluctuation is small, has low suction capacity, noise, efficient, long lifespan, reliable operation；And the advantages of its protrusion is conveying
Vortex is not formed during medium, to the sticky insensitive of medium, can transfer of highly viscous medium.
Integrated screw rod is mainly used inside traditional screw pump, helical blade is all directly to be fixed on screw sleeve,
This is resulted in use, when indivedual helical blades are damaged because wearing or corroding when reason, just has to replace whole
Root screw rod, like this, not only replacement operation is complicated, but also the cost repaired is higher, also results in the waste of resource.
It is that this practicality is new for a kind of separation-type screw for being suitable for pump class of above-mentioned problem existing in the prior art design
The purpose of type research.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model lies in that provide a kind of separate type spiral shell for being suitable for pump class
Bar, can effectively solve the problem that the above-mentioned problems of the prior art.
The technical solution of the utility model is：
A kind of separation-type screw for being suitable for pump class, includes screw body, the screw body include screw sleeve and
Rotor, the rotor embedded device is inside screw sleeve；The outer surface annular of the screw sleeve is provided with some helical blades, institute
State screw sleeve and be equipped with spiral helicine mounting groove in the junction of corresponding helical blade；Positioned at the screw sleeve high order end and low order end
Helical blade be fixed in the mounting groove；The helical blade is arranged to semi-spiral shape, helical-blade described in adjacent two panels
Piece is respectively equipped with corresponding fixture block and card slot in junction.
The advantages of the utility model：
The utility model includes screw sleeve, rotor and helical blade.Except screw sleeve high order end and the helical-blade of low order end
Outside piece, remaining helical blade coordinates detachable apparatus by spiral helicine mounting groove, and adjacent two panels is spiral on screw sleeve
It is clamped between blade by the cooperation of fixture block and card slot.Therefore when indivedual helical blades can not be made due to reasons such as abrasions
Used time, only need to pull down replacement by corresponding helical blade, not have to not only so replace whole screw rod, but also replacement operation is simple,
Maintenance cost is reduced at the same time, avoids the waste of resource.The utility model is not only simple in structure, and can reduce maintenance cost
With avoiding the waste of resource.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the structure diagram of screw sleeve.
Fig. 3 is the structure diagram of fixture block and card slot.
Embodiment
In order to facilitate the understanding of those skilled in the art, existing make embodiment combination attached drawing into one the structure of the utility model
Step is described in detail：
With reference to figure 1-3, a kind of separation-type screw for being suitable for pump class, includes screw body 1, the screw body 1 wraps
Containing screw sleeve 2 and rotor 3,3 embedded device of rotor is inside screw sleeve 2；The outer surface annular of the screw sleeve 2 is set
There are 12 pieces of helical blades 4, the screw sleeve 2 is equipped with spiral helicine mounting groove 5 in the junction of corresponding helical blade 4；It is located at
The helical blade 4 of 2 high order end of screw sleeve and low order end is fixed in the mounting groove 5；The helical blade 4 is arranged to half
Helical form, helical blade 4 described in adjacent two panels are respectively equipped with corresponding fixture block 6 and card slot 7 in junction.
The utility model includes screw sleeve 2, rotor 3 and helical blade 4.Except 2 high order end of screw sleeve and the spiral shell of low order end
Outside vane piece 4, remaining helical blade 4 coordinates detachable apparatus on screw sleeve 2 by spiral helicine mounting groove 5, adjacent
It is clamped between two panels helical blade 4 by the cooperation of fixture block 6 and card slot 7.Therefore when indivedual helical blades 4 are due to abrasion etc.
Reason and can not only not have to so replace whole screw rod in use, corresponding helical blade 4 need to only be pulled down to replacement, but also
Replacement operation is simple, while reduces maintenance cost, avoids the waste of resource.
The above is only the preferred embodiment of the present invention, it is all done according to present utility model application the scope of the claims it is equal
Deng change and modify, should all belong to the covering scope of the utility model.
