Abstract
The utility model discloses a conical single-screw pump, including an outer sleeve, a spiral stator bush and a spiral rotor screw. A cavity is formed in the middle of the spiral stator bush, and the spiral rotor screw is provided inside the cavity; the spiral stator bush and the spiral rotor screw correspond to each other at the axial direction to present a geometric-form, and then present a conical figure from one end to another end, and the profile of the conical form falls on a conical camber without paralleling to the central line of a rotating shaft; the cross section of the cavity of the spiral stator bush presents a flat-circular figure or a triangular figure; a spiral cavity structure is provided between the two sides of the spiral stator bush and the outer sleeve. Comparing with the prior art, the conical single-screw pump has obvious advantage: the rotor and the stator spiral bodies of the conical single-screw pump present a conical form, and can do concentric rotation, which omits a cardan universal joint; the rotating torque of the conical single-screw pump is increased with high pressure and simple structure; the calibre of a stub end of the conical single-screw pump is increased, so that the feeding capability is enhanced; the interstice of the conical single-screw pump can be adjusted and repaired, so that the service life of the conical single-screw pump can be prolonged by 3-5 times; when the conical single-screw pump is used as a food pump, the food spoilage chance caused by the foodstuff remaining in the interstice of the cardan universal joint can be eliminated, for the conical single-screw pump is not provided with the cardan universal joint.
Description
Technical field
The utility model relates to a kind of pumping machine, relates in particular to a kind of helical rotor pump, particularly a kind of taper helical rotor pump.
Background technique
Helical rotor pump is a kind of simple in structure, positive displacement pump that efficient is high, is made up of the power plant and the pump housing.The pump housing generally is made up of overcoat, helical stator lining and helical rotor screw rod, forms a cavity in the middle of the helical stator lining, and the helical rotor screw rod is arranged in this cavity.Screw rod and stator form bus or outer profile is parallel to rotating shaft center's line, drop on the Cylinder surface, and corresponding points are cophasing periodically, and equidistant with central axis.By power plant, drive the screw rod to-and-fro motion, in pump, produce pressure, thus can conveyance fluid or other loose material.The characteristics of helical rotor pump are: it can carry mobile medium neutral or that abrasion is stronger, high viscosity, the fibre-bearing that also can centrifugal pumps can't carry, contain solid particulate matter, contain gas, the medium of mobile difference, as sewage in the sewage treatment and mud.Thereby helical rotor pump is applied in the industries such as oil, environmental protection, chemical industry, papermaking, metallurgy, building, mine, sugaring and food widely in China.Helical rotor pump is in carrying above-mentioned substance, resemble mud, abrasion is stronger, very fast excesssive gap is ground away, formed to stator, can't use, directly influence is produced, and some unit has to abandon using the helical rotor pump simple, that cost is low, efficient is high, and uses two screw pump complicated, that cost is high, power consumption is high.Trace it to its cause, traditional helical rotor pump defectiveness, entity stator frictional force is big, produces the gap and is difficult for auto-mending, and cooperating between rotor and the stator fixed.Thereby, the wearing and tearing of helical rotor pump and working life, become the key point that can helical rotor pump in use bring into play efficient.For this reason, the entrepreneur does all effort, improves the helical rotor pump structure, makes it bring into play better efficient.
Summary of the invention
Technical problem to be solved in the utility model is: traditional helical rotor pump exists entity stator frictional force big, produces the gap and is difficult for auto-mending, and cooperating between rotor and the stator fixed.
The utility model for the technological scheme that the problems referred to above adopted that solves the prior art existence is: a kind of taper helical rotor pump, comprise overcoat, helical stator lining and helical rotor screw rod, form a cavity in the middle of the helical stator lining, the helical rotor screw rod is arranged in this cavity, it is characterized in that: described helical stator lining passes through with the corresponding geometrical shape of described helical rotor screw axial and is the taper body, the not parallel rotating shaft center of outer profile line drops on the conical camber.
Further, between described helical stator lining both sides and the described overcoat spiraled cavity structure is set.
Further, its cross section of cavity that forms in the middle of the described helical stator lining is oblate shape body.
Further, its cross section of the cavity shape body triangular in shape that forms in the middle of the described helical stator lining.
Compared with the prior art the utility model has conspicuous advantage: the rotor of traditional helical rotor pump rotates in different capable stator, rotor is done moving up and down of not feeling relieved, and motor reducer is the centering rotation, so just must use universal joint to realize the moment transmission of or not from feeling relieved.And the rotor of taper helical rotor pump, the tapered shape of stator heliconid, spirochetal eccentricity value progressively dwindles, and it is 0 that some eccentricity values finally must be arranged, driving torque can be done concentric rotation on 0 o'clock like this, thereby, just can save universal joint, can realize equally from the rotation of or not of feeling relieved; Save the universal joint of complex structure seal request strictness, can reduce the device fabrication cost significantly, designs simplification uses simple; Moment of rotation increases, pressure height, efficient height; Taper helical rotor pump stub end bore increases, and the charging ability is strong, and especially the strong characteristics of viscous medium charging are more obvious; Gap between straight shape helical rotor pump rotor stator is fixed, and the wearing and tearing back is difficult for adjusting or repairing.And the gap of taper helical rotor pump can be adjusted and repair, and the axle position of adjusting threaded spindle and stator just can change both radial clearances or interference, can prolong 3-5 working life doubly; When the taper helical rotor pump is done the food pump use, can not eliminate food residue causes causing food spoilage in the universal joint slit chance because there is universal joint.
