Abstract
The utility model relates to a single screw pump, comprising three parts of an outer shell, a screw, round roller-shaped vanes. The single screw pump is characterized in that the outer shell comprises a cylindrical cavity and an annular slide groove. An axial through groove is arranged on the cylindrical cavity to be communicated with the annular slide groove. The screw is arranged in the cylindrical cavity. The screw is dissected and viewed along an axial direction, and the thread surface of the screw is in the shape of a circular arc. A group of round roller-shaped vanes are arranged in the annular slide groove, and are engaged with the screw in the cylindrical cavity by the axial through groove. The single screw pump has the advantages of simple structure, even flow quantity, low noise, no pulsation property, and easy processing and manufacture. The single screw pump can be used for transporting liquid.
Description
The utility model relates to a kind of helical rotor pump.
In the prior art, helical rotor pump adopts screw rotor gear motion and liquid is carried in the axial motion that forms closed chamber in stator liner mostly, because the processed complex of stator liner, the wearing and tearing of screw rotor and stator liner are more serious again, so user cost is higher.And this gear motion can produce bigger additional dynamic load, has influenced the stationarity of motion, so be easy to generate the flow shakiness, and problem such as voice is big.The utility model provides a kind of helical rotor pump for this reason, can overcome above problem.
The technological scheme that the utility model adopted is: this helical rotor pump comprises shell, screw rod, circle roll forming blade three parts, and shell comprises a cylindrical chamber and an annular groove, opens an axial through slot and make it to communicate with annular groove on cylindrical chamber; Screw is in cylindrical chamber, and it is circular arc that screw rod is analysed and observe its flank of thread vertically, and one group of round roll forming blade is contained in the annular groove, sees through the screw engages in axial through slot and the cylindrical chamber.Owing to adopted technique scheme, thus this pump have simple in structure, flow is even, noise is little, pulsating movement free, be easy to the advantage of processing and fabricating, can be used for carrying liquid.
Below in conjunction with accompanying drawing the utility model being done one describes in detail.
Fig. 1 is a cut-away view of the present utility model;
Fig. 2 is an A-A sectional drawing of the present utility model
As shown in Figure 1, helical rotor pump comprises shell 1, screw rod 4, circle roll forming blade 5 three parts, and shell 1 comprises a cylindrical chamber 2 and an annular groove 3, opens an axial through slot 6 and make it to communicate with annular groove 3 on cylindrical chamber 2; Screw rod 4 is contained in the cylindrical chamber 2, and it is circular arc that screw rod 4 is analysed and observe its flank of thread vertically, and one group of round roll forming blade 5 is contained in the annular groove 3, sees through screw rod 4 engagements in axial through slot 6 and the cylindrical chamber 2.Screw rod 4 rotation in cylindrical chamber 2 under power drives like this, liquid is screwed on along screw thread, and circle roll forming blade 5 is rolling in annular groove 3 under the drive of screw rod 4 or is sliding, round roll forming blade 5 by cylindrical chamber 2 one sides is sealed through slot 6, thereby the liquid that is screwed on can only be made progress along screw thread, flow out from the other end of cylindrical chamber, reach the purpose of carrying liquid.
Wherein, between the screw thread tooth top of the inwall of cylindrical chamber 2 and screw rod 4, between annular groove 3 and the circle roll forming blade 5, should guarantee sealing between the flank of thread of circle roll forming blade 5 and screw rod 4.
