When in work, friction heat of the stator rubber can be betterconducted to the stator steel tube through the framework and cooled by well liquid, thus improving the running efficiency and service life of a screw pump.
Description
One, technical field:
The utility model relates to the stator of screw pump, what be specifically related to is to be applied to the screw pump stator that screw pump is manufactured, can be significantly improved screw pump quality and performance.
Two, background technique:
Screw pump is made up of stator and rotor, and rotor is high strength, fine finishing, surperficial coated screw rod; Fig. 1 is the structural representation of existing screw pump stator, and as figure, stator is that synthetic rubber firm, the anti-corruption of oil resistant is adhered to the pump barrel in the steel shell, and the rubber internal surface is the stator profile.Can stator rubber be subjected to many-sided influences such as high pressure, frictional heat, gas and running fatigue during screw pump work, adapt to running efficiency and the working life that these influence factors directly determine screw pump so the stator rubber quality is a stator rubber.The parameter of decision stator rubber mechanical-physical and chemical property has a lot of, but these performance parameters are mutual restriction, a performance index height, will influence other performance index, therefore, be difficult to find optimum rubber compounding on the one hand, single on the other hand quality from rubber compounding aspect consideration raising screw pump will inevitably be limited to.
Three, summary of the invention:
The purpose of this utility model provides a kind of screw pump stator, and this screw pump stator is used to solve existing screw pump stator rubber makes unfavorable problem of screw pump operational efficiency, working life.
The technological scheme that its technical problem that solves the utility model adopts is: this screw pump stator comprises stator steel pipe and stator rubber, have skeleton in the stator rubber, one side of skeleton adapts with the shape of stator steel pipe inwall, and skeleton is fixed together by this limit and stator steel pipe.
The limit that skeleton and stator steel pipe are fixed together in the such scheme is straight flange or shape in the shape of a spiral, and the another side of skeleton is mutually neat or parallel with the stator molded lines.
Skeleton in the such scheme adopts hole structure, and skeleton adopts steel plate or steel disc.
Screw pump stator design in the such scheme has stiffening rib, stiffening rib to be fixed on the skeleton or is fixed on the stator steel pipe, and stiffening rib adopts steel wire or high strength cotton rope.
Further be that skeleton or stiffening rib in the such scheme is evenly distributed in the stator rubber.
Beneficial effect:
1, the utility model can significantly improve the adhesive property of stator rubber because of the bond area of stator rubber and stator steel pipe reaches the effect of stiffening rib greatly.
2, the utility model can effectively limit the swelling set of stator rubber because of having skeleton or stiffening rib and stator rubber bonding.
3, rubber good heat dissipation, the temperature of rubber directly influences the hardness of rubber, and temperature raises, and hardness reduces, and its wear resistance is variation also, and then causes reduce the working life of screw pump.The utility model skeleton or stiffening rib are evenly distributed in the stator rubber, and more much better than rubber because of their capacity of heat transmission, the stator rubber frictional heat in screw pump when work can be transmitted on the stator steel pipe by skeleton or stiffening rib and by the well liquid cooling but preferably.
4, the utility model can reduce the starting torque of screw pump.
5, the utility model can effectively improve the phenomenon of the special media lower rotor part fluctuation of speed.
6, the utility model has improved the operational efficiency and the working life of screw pump.
