Abstract
The utility model relates to an equal strength composite lining for a stator of a single screw pump, which can be applied to a ground pump and a down-hole pump on an oil field. The composite lining is formed by that the inner hole of a metallic cylinder stator is coated with an adhesive after cleaned and then is injected with a hard rubber attached lining; after the attached lining is cleaned through vulcanizing drawing and is coated with an adhesive, a working elastic body lining is injected. The utility model has the advantages of good service performance, good-quality lining working elastic body saving and low cost; though the design of a mould core is troublesome, manufacture is easy.
Description
One, technical field: the utility model relates to a kind of helical rotor pump stator equal strength compound lining, can be applicable to surface pump and oil field underwell pump.
Two, background technique: conventional helical rotor pump stator is to be made of interior pipe metal borehole jack lining rubber, and the rubber internal surface is the stator profile.Because stator type upper thread type difference, profile each point normal does not wait apart from the metal pipe-wall distance, and screw rod is bad in interior stress, causes screw pump single-stage pressure-bearing value low.For improving the screw pump stress, wall thickness rubber lining stators such as metal mold housing have appearred.Wall thickness rubber lining stators such as metal mold housing have improved screw pump single-stage pressure-bearing value, but metal mold housing manufacture cost height; Poor Deng the thin damping performance of wall thickness rubber, mechanical property that rubber is thick is bad.
Three, summary of the invention: for solving the above-mentioned deficiency of prior art, the utility model adopts conventional pipe metal borehole jack stator tube, by the shaping of design inner liner portion ebonite, and again by the requirement of screw pump usability, each contact points equal strength lining internal layer work elastomer.Screw pump changes, each contact points interference of stator, and stator elastomer contact points normal stress is relevant with normal direction amount of deformation, apparent modulus of elasticity etc., takes into full account various factors design rubber core rod, reaches each contact points top layer work elastomer normal stress approximately equal.Compression strength approximately equal when stator equal strength compound lining refers to internal layer elastomeric liner top layer and screw engages is not to wait strain, so the internal layer elastomer thickness depends on environment adjacent, is not to wait wall thickness.Metal stator pipe lining ebonite earlier plays buffering and helps the inner lining design.Its advantage is good usability, saves high-quality liner work elastomer, though core rod design trouble helps making, cost is low.
Four, description of drawings: Fig. 1 is a structural representation of the present utility model.
Five, embodiment: as can be known referring to Fig. 1, the utility model is to be made of metallic cylinder stator tube 1, the attached lining 2 of ebonite and work elastomer liner 3, be marked with the attached lining 2 of ebonite after the aperture cleaning scribbles tackiness agent in the metallic cylinder stator tube 1, attached lining 2 is marked with work elastomer liner 3 after coating adhesive is cleared up in the sulfuration molding again.
