To achieve these goals, the technical solution of the utility model is as follows:
A kind of pulsating movement free rotor pump (Q type) comprises rotating shaft and the bearing that is connected with rotating shaft, and described rotating shaft and described bearing be arranged in parallel, and described rotating shaft is provided with at least one helical rotor, and described helical rotor is evenly distributed in the rotating shaft.
Described helical rotor comprises rotor subject and the oblique wing, is arbitrarily angled degree helical between any two adjacent described oblique wings and connects.
Adjacent two described oblique wings are " S " font.
Described helical body be equipped with the described oblique wing up and down, and the described declivity wing of going up is staggered.
Described helical rotor is two, three, four, six or eight.
Described helical rotor is fixed by pressure disk and clamping bolt and described rotating shaft.
Described rotating shaft is provided with wearing plate.
Described helical rotor is sheathed in the described rotating shaft.
Adopt the on-the-spot maintenance type fast of technique scheme, detachable rotor pump, the axle of pumping chamber is equipped with mechanical seal, rotor, wearing plate on the one hand, reaches pump action; On the other hand, can be by easily moving axially end cap, the easily damaged parts with the pump chamber part comprises rotor, wearing plate, mechanical seal, does not need to dismantle pump at the scene and imports and exports under the situation of pipe fitting and the pump housing, changes.The custom-designed structure of pump is guaranteed easily to move axially, and is convenient for changing pump chamber part easily damaged parts; comprise rotor, wearing plate, mechanical seal, minimum level reduces shutdown loss, improves the pump utilization efficiency; adopt the bolt rotor simultaneously, the rotor pump pulsating movement free is carried when guaranteeing to carry.
Description of drawings

Fig. 2 is the structural representation of helical rotor number when being one.
Embodiment:
Be easy to understand understanding in order to make technological means of the present utility model, creation characteristic and to reach purpose, further set forth the utility model below in conjunction with specific embodiment
As shown in Figure 1, a kind of pulsating movement free rotor pump (Q type), comprise rotating shaft and the bearing that is connected with rotating shaft, described rotating shaft and described bearing be arranged in parallel, described rotating shaft is provided with at least one helical rotor, described helical rotor is evenly distributed in the rotating shaft 2, and rotating shaft 2 is fixed on the rotor pump shell 1.And the other end is fixed into an integral body by a rotor cover 4.
Described helical rotor comprises rotor subject 32 and the oblique wing 31, is arbitrarily angled degree helical between any two adjacent described oblique wings and connects.Adjacent two described oblique wings are " S " font.Described helical body be equipped with the described oblique wing up and down, and the described declivity wing of going up is staggered.Described helical rotor is two, three, four, six or eight.Described helical rotor is fixed with described rotating shaft by pressure disk 5 and clamping bolt 6.Described rotating shaft is provided with wearing plate.Described helical rotor is sheathed in the described rotating shaft.Helical rotor connects and transmission with axle 2.
Move axially the principle of changing easily damaged parts: the end cap screw that comes loose, the clamping bolt that comes loose moves axially pressure disk, move axially rotor, move axially mechanical seal, can will take out the original paper that needs replacing easily then, after then it being changed, just its assembling can be finished according to opposite order.
Running fix pin and clamping bolt, the pump case of can radially adjusting and axially superpose.Isolated chamber installs the pressurization oil tank additional and plays the effect of rotor pump integral sealing.
The utility model discloses pulsating movement free rotor pump (Q type), a kind of scene maintenance type fast, detachable pump comprises rotating shaft and the bearing that is connected with rotating shaft, and described rotating shaft and bearing be arranged in parallel, and be on the same horizontal plane, described rotating shaft is provided with helical rotor, and described helical rotor can be single, also can be made up of many helical rotor groups, be evenly distributed in the rotating shaft, and helical rotor and rotating shaft are that key is in transmission connection; Described helical rotor is fixing by pressure disk and clamping bolt and axle.The utility model has solved rotor pump field maintenance and need not to dismantle pump import and export pipeline by custom-designed structure, under the single manual situation, changes the technical barrier of pump chamber part spare part.
The utility model also discloses a kind of friction rotor and rotor pump, and wherein the friction rotor has the oblique wing, and the described oblique wing is shape in the shape of a spiral.Rotor pump comprises that a pair of rotor twin shaft to rotation structure, which is provided with rotor, and described rotor has the oblique wing, and the described oblique wing is shape in the shape of a spiral, and the contacted oblique wing of these two rotors is right-handed screw and backpitch.The friction rotor that the utlity model has not only shows friction conveying function advantage, also has other application.For example, adopt the friction rotor, the suction performance of pump will be enhanced.The most important thing is, broken through flow and limited the factor of raising because of vibration, broken through pump flow can by increase that revolution speed increases may, improve the stability of pump, prolonged pump working life.
