The utility model discloses can be effectively thermal -insulated, prevent that the vulcanite coating from ageing, warping because of long -time overheated leading to to zirconia base ceramic coating can improve the heat -resisting fastness to wear of rotor, has improved screw rod drilling tool motor's life greatly.
Description
Technical field
The utility model relates to the motor configured with helicoid hydraulic motor in petroleum and natural gas wellbore construction.
Background technology
Helicoid hydraulic motor is a kind of is power with drilling fluid, fluid pressure can be transferred to the positive displacement mud motor of mechanical energy.The slurry flows pumped when slush pump enters motor through bypass valve, forms certain pressure differential at the import and export of motor, and drive rotor rotates around the axis of stator, and rotating speed and moment of torsion are passed to drill bit by universal drive shaft and power transmission shaft, thus realizes drillng operation.Existing screw drilling tool motor uses rubber as the liner of motor stator usually, but the high temperature resistant degree of rubber is low, in the high temperature well of temperature higher than 150 degree, rubber liner very easily damages motor by heat ageing distortion, and develop other resistant to elevated temperatures elastomeric material high costs and cannot extensive use of resistance to wearing, therefore, the life-span of existing screw drilling tool motor generally can not more than 150 hours.
Summary of the invention
For above-mentioned prior art, the purpose of this utility model is to provide a kind of screw drilling tool motor, this motor by install additional stator casing coating, the uniform rubber liner of thickness and rotor zirconia-based ceramics coating can effectively thermal resistance, to be resistance toly heated, wear-resisting, and greatly improve the life-span.
The technical scheme in the invention for solving the technical problem is:
A kind of screw drilling tool motor, comprise stators and rotators two large divisions, described stator comprises the stator body that inner surface has continuous helical line, vulcanized rubber liner and stator casing coating, described rotor comprises cross section and is octagon and center has rotor body and the zirconia-based ceramics coating of through hole, wherein, the each several part thickness of vulcanized rubber liner is equal, and external surface and stator inner surface match, stator casing coating uniform be coated in stator casing external surface, zirconia-based ceramics coating outer surface has the continuous helical line matched with stator body continuous helical line, and the summit in zirconia-based ceramics coating thickness, the summit of rotor body cross section octagon and central point conllinear all the time.
Adopt such structure design, can effective thermal resistance by stator casing coating, prevent motor internal temperature too high, after the vulcanized rubber liner that each several part thickness is equal is heated, distortion evenly, can not affect the rotation of rotor, unique connected mode of the rotor body of zirconia-based ceramics coating and cross section octagon can strengthen snap-in force between the two, can not come off because rotor high-speed rotates, the consumption of zirconia-based ceramics material can be saved simultaneously, save cost.
As further improvement of the utility model, the continuous helical line that the stator body had for the utility model and zirconia-based ceramics coating have is 8.
Adopt such continuous helical line design, the moment of torsion of rotor can be improved, increase large rock-carrying ability, improve moyor.
Further improve as of the present utility model, the zirconia-based ceramics coating maximum gauge had for the utility model and the ratio of minimum thickness are 5 ﹕ 1.
Adopt such zirconia-based ceramics coated designs, it is the most rational conclusion drawn according to crystal structure and the character of zirconia-based ceramics material, this Thickness Ratio can reach maximum mechanical strength while saving material, prevents zirconia-based ceramics coating from causing fragmentation because rotor high-speed rotates.
Further improve as of the present utility model, the stator body had for the utility model and the material of rotor body are metal or metal alloy, the material of stator casing coating is modified organic silicone resin, and the material of zirconia-based ceramics coating is the tetragonal zircite base pottery of the yttria toughened agent containing mass fraction 2%.
Such material is adopted to select, because modified organic silicone resin has good heat-proof quality and heat acclimation ability, 2% yittrium oxide can increase the toughness of zirconia-based ceramics coating as the flexibilizer of zirconia-based ceramics, fundamentally avoid ceramic materials to cause coating breaks down because fragility is large, and then strengthen motor application life.
In a word, when using a kind of screw drilling tool motor of the present utility model, can higher temperature be adapted to, in the aging minimizing screw motor application life avoiding vulcanized rubber liner too early, can large rock-carrying ability be increased simultaneously, reducing use cost.
