Fluid gets through the guide blades (4) on the stator (2) and rushes to the rotor vanes (7) on the rotor (6), the fluid from the rotor (6) enters into the guide blades (4) of the next set of stators (2) again, the guide blades (4) are used for guiding the fluid to make the fluid rush to the rotator (6) again, the rotor (6) rotates and transmits torques through the cooperation of the rotor inner screw thread (5) and a rotating shaft (8) to make the rotating shaft (8) rotate successfully.

Description

A kind of turbine rotor stator

One, technical field:

The utility model relates to a kind of power drilling tool that is used for the underground work of petroleum drilling operation and workover treatment, especially relates to the turbo-power drilling tool rotor stator that a kind of fluid promotes.

Two, background technology:

At present, the mud motor of oil and gas well drilling mine locating industry at home and abroad, use be helicoid hydraulic motor and turbodrill, stator on the turbodrill and rotor are fixed as end thread and compress.When the assembling of rotor and stator turbine join finish after, utilize thrust between rotor and the rotor and the thrust between stator and the stator, differ and combine, and separate between rotor set and the stator pack, stator pack is not rotated, and rotor set is rotated.Existing turbodrill rotating speed height, assembling inconvenience.Helicoid hydraulic motor is made up of elastomer stator and rigidity rotor, and rotor rotates under swing state, existing helicoid hydraulic motor non-refractory and soda acid, the down-hole that is applied to usually with good conditionsi.

Three, utility model content:

A kind of turbine rotor stator of the utility model, technical problem to be solved provides a kind of field-installed turbodrill of being convenient to, when assembling, rotor matches with rotating shaft with screw thread, decided and stator between join promptly when carrying out drillng operation with screw thread, utilize the threads engaged on epitrochanterian screw thread and the axle to form rotor set, stator utilizes the threads engaged between the stator to form stator pack, makes the rotation smoothly under the promotion of high-velocity fluid of stator pack and rotor set.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of turbine rotor stator, be screw thread in comprising, in under outer on the rotor subject of arc shaped blade and the shell screw thread is arranged outward, there is the stator body of pilot fluid blade the centre, and thread spindle is formed, it is characterized in that: the rotor subject internal circular surfaces is a screw thread, the 28-40 blade of arc is arranged outward, on the stator body shell external screw thread is arranged, under the shell internal thread is arranged, the centre is the 28-40 guide vane, and rotating shaft is a thread spindle.

In the above-mentioned rotor subject round thread be convenient to rotating shaft on threads engaged, the 28-40 blade of arc is arranged outward.Stator body shell upper end cylindrical is a screw thread, and the garden is a screw thread in the lower end, and the centre is the 28-40 guide vane, is threaded connection between stator and the stator.Rotor and stator cooperatively interact and constitute the turbine group, and when fluid flowed, by the guide effect of stator 28-40 sheet blade, the 28-40 blade that fluid rushes at rotor formed the rotor rotation.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

1, the utility model is worked as fluid under the effect of 28-40 guide vane, fluid impact rotor 28-40 blade forms and rotates, rotatory force is passed to rotating shaft by screw thread, can not occur rotating because of the axle that tightly do not drive that rotor is pressed, can not cause rotor decentraction and the stator minimizing moment of torsion that rubs mutually because of key cooperates yet, can make rotor under the effect of fluid, drive rotating shaft and rotate smoothly, and use assembling very convenient.

2, the utility model is when fluid passes through stator 28-40 blade guide effect, and fluid obtains shunting.

Four, description of drawings:

Fig. 1 is stator structure figure of the present utility model

Fig. 2 is a rotor structure figure of the present utility model

Fig. 3 is the textural association sectional drawing of stator of the present utility model, rotor and rotating shaft

Among the figure: 1-stator external screw thread, 2-stator, 3-stator internal thread, 4-stator guide vane, 5-rotor internal thread, 6-rotor, 7-rotor blade, 8-rotating shaft

Five, the specific embodiment:

Referring to Fig. 1, Fig. 2 and Fig. 3, the turbine group that the utility model is made up of a kind of turbine rotor stator is made up of stator (2), stator external screw thread (1), stator internal thread (3), stator guide vane (4), rotor internal thread (5), rotor (6), rotor blade (7), rotating shaft (8).On the stator (2) in the turbine group that stator (2) and rotor (6) are formed 28-40 sheet stator guide vane (4) is arranged, there is stator external screw thread (1) its upper end, and there is stator internal thread (3) lower end, constitutes a stator (2) jointly.Adopt the threaded connection of self to form stator pack between stator (2) and the stator (2).On the rotor (6) in the turbine group that stator (2) and rotor (6) are formed 28-40 sheet rotor blade (7) is arranged, rotor internal thread (5) is arranged on the rotor (6), constitute a rotor (6) jointly.Adopt the threaded engagement in screw thread and the rotating shaft (8) to form the multi-stage rotor group between rotor (6) and the rotor (6).Rotor set is serially connected in the rotating shaft (8).The every dress adorned a rotor (6) behind the stator (2) and refilled stator (2) rotor (6), forms to intersect assembling, forms the turbine group, makes the turbine group make rotating shaft (8) rotation smoothly under hydrokinetic effect.

During actual the use, fluid makes fluid rush at 28-40 rotor blade (7) on the rotor (6) under the effect of the 28-40 stator guide vane (4) on the stator (2).The fluid that comes out from rotor (6) 28-40 stator guide vane (4) convection cell that enters on next group stator (2) again leads, and makes fluid rush at 28-40 rotor blade (7) on the rotor (6) once more.Rotating shaft 8 is rotated, and cooperates with rotating shaft (8) by the screw thread (6) on the rotor (6) and to carry out transfer torque, passes to rotating shaft (8) then, makes that rotating shaft (8) is smooth rotates.
