Pump case can move radially and axially stack, has reduced on the one hand rotor replacement cost; Avoid on the other hand pump case cast inblock, pump case bad adaptability, cannot axially superpose, and reduces pump cost.
Large volume isolated chamber, outside installs pressurization oil tank additional.Can sufficient lubrication and cooling mechanical seal, improve the working life of mechanical seal, and guarantee rotor pump overall sealing performance, without any outside leakage.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of pulsating movement free rotor pump (Q type), has solved not dismantling pump import and export pipe fitting, without specialist tools, in single manual situation, cannot move axially the technical barrier of pumping chamber spare part.
To achieve these goals, technological scheme of the present invention is as follows:
A kind of pulsating movement free rotor pump (Q type), comprises rotating shaft and the bearing being 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 rotating shaft.
Described helical rotor comprises rotor subject and the oblique wing, is arbitrarily angled degree helical and connects between any two adjacent described oblique wings.
Adjacent two described oblique wings are " S " font.
Described helical body be equipped with up and down the described oblique wing, and the described upper declivity wing 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 described rotating shaft.
Adopt the on-the-spot rapid-maintenance type 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, by easily moving axially end cap, by the easily damaged parts of pump chamber part, comprise rotor, wearing plate, mechanical seal, not need at the scene to dismantle pump and import and export in the situation of pipe fitting and the pump housing, change.The custom-designed structure of pump, guarantees 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 pump utilization efficiency; adopt bolt rotor, while ensureing to carry, rotor pump pulsating movement free is carried simultaneously.

Embodiment:
Be easy to understand understanding in order to make technological means of the present invention, creation characteristic and to reach object, further set forth the present invention 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 being 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 rotating shaft 2, and rotating shaft 2 is fixed on a rotor pump shell 1.And the other end is fixed into an entirety by a rotor cover 4.
Described helical rotor comprises rotor subject 32 and the oblique wing 31, is arbitrarily angled degree helical and connects between any two adjacent described oblique wings.Adjacent two described oblique wings are " S " font.Described helical body be equipped with up and down the described oblique wing, and the described upper declivity wing 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 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, then can will take out easily the original paper that needs replacing, then, after being changed, just its assembling can be completed according to contrary order.
Running fix pin and clamping bolt, the pump case of can radially adjusting and axially superpose.Isolated chamber installs pressurization oil tank additional and plays the effect of rotor pump integral sealing.
The invention discloses pulsating movement free rotor pump (Q type), a kind of on-the-spot rapid-maintenance type, detachable pump, comprises rotating shaft and the bearing being connected with rotating shaft, and described rotating shaft and bearing be arranged in parallel, and in same level, 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 rotating shaft, and helical rotor and rotating shaft are that key is in transmission connection; Described helical rotor is fixed by pressure disk and clamping bolt and axle.The present invention, by custom-designed structure, has solved rotor pump field maintenance without dismounting pump inlet/outlet pipeline, in single manual situation, changes the technical barrier of pump chamber part spare part.
The present invention also discloses a kind of Non-vibration rotor and rotor pump, and wherein Non-vibration rotor has the oblique wing, and the described oblique wing 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 in the shape of a spiral, the oblique wing that these two rotors contact is right-handed screw and backpitch to the described oblique wing.The Non-vibration rotor that the present invention has, not only shows friction conveying function advantage, also has other application.For example, adopt Non-vibration 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 increase may, improve the stability of pump, extended pump working life.
