Description
Technical field
The present invention relates to a kind of bonnet dismantling device for quantitatively applying super-huge torque for drilling pump.
Background technology
Drilling mud pump is described as the heart equipment of rig, and rig wants drilling well, it is necessary to provides foot with drilling mud pump
The slurry fluid of enough big pressure and enough huge discharges circulates in rig and well.As shallow oil is fewer and fewer, drilling well is more past
Deep production, plus the efficiency that constantly improve drilling well, these require that drilling mud pump provides higher pressure, more huge discharge
Slurry liquid.
The mud hydraulic coupling more high flow capacity that drilling mud pump provides is bigger, requirement to drilling mud pump just more and more higher,
It is particularly such to the fluid end of the direct contact of slurry liquid.
Fluid end will constantly suck the slurry liquid of low pressure, the slurry liquid of high-pressure large-displacement be gone out by pressurized delivered, directly
Suction and discharge slurry liquid piston, cylinder sleeve, valve body, valve seat become consumable accessory, it is necessary to often more renew piston, cylinder sleeve,
The parts such as valve body, valve seat, therefore just need to be designed with the passage of the parts such as replacing piston, cylinder sleeve, valve body, valve seat in fluid end,
And on passage clamping piston, cylinder sleeve, valve body, valve seat compressing component.Clamping piston, the part of cylinder sleeve are referred to as cylinder sleeve pressure
Lid, the part for compressing valve body and valve seat is referred to as bonnet, in compressing member and is compacted in part and also has the close of prevent leakage high-pressure slurry liquid
Seal, the sealing ring of sealing piston cylinder sleeve are referred to as cylinder liner packing ring, and the sealing ring of seal valve seat and valve body is referred to as valve bonnet seal circle.
Because the mud hydraulic coupling of fluid end inner chamber is especially high, cylinder sleeve gland and bonnet as compressing component must be held
By the pressure of slurry liquid, in all compressing members for bearing mud hydraulic coupling, the pressure of bonnet is maximum, such as 7 inches of bonnet,
When mud hydraulic coupling is 51.7MPa, the pressure that a bonnet will bear slurry liquid is 1060000N.
The bonnet thrust overwhelming majority is compressed by thread connection at present.Because thread connection has many good qualities：Structure
Simply, it is convenient to mount and dismount；Thread connection equlvalent coefficient of friction is big, as long as suitable control lead angle, you can obtain good self-locking
Property, therefore the reliability connected is very high.Belong to and be fastenedly connected for the thread connection of bonnet and fluid cylinder, when fluid cylinder does not work
Just there are enough pretightning forces to screw thread, that is, when screw thread is not worked by highly pressurised liquid, make the screw thread and liquid of bonnet
The screw thread of cylinder produces elastic deformation, the screw thread elongation of bonnet, and the screw thread of fluid cylinder is compressed.The effect of this pretightning force is：It is anti-
Only after high-pressure slurry liquid pressurizes to bonnet, remain to make bonnet not loosen, firmly compress valve bonnet seal circle, ensure sealing ring
Compactness, do not allow the slurry liquid of high pressure to be sprayed and spill.And pretightning force is suitable：Pretightning force must be greater than highest mud hydraulic pressure
Power if pretightning force is inadequate, is just unable to sealed valve cap sealing ring, causes Lou slurry liquid to the pressure of bonnet, and pretightning force is inadequate,
Run into slurry liquid fluctuation it is very big when, can also constantly be loosened because of bonnet（When mud hydraulic coupling is more than pretightning force）, constantly compress
（When mud hydraulic coupling is less than pretightning force）, loosen and compression alternately and repeatedly carried out, it will destroy the screw thread of bonnet and fluid cylinder, even
There is the non-detachable serious consequence of screw thread adhesion of bonnet and fluid cylinder；But can not pretightning force it is too big, because pretightning force is too big,
Accidentally overload in the course of the work, exceeded the intensity of screw thread, destroy the screw thread of bonnet and fluid cylinder.Therefore must science system
Determine the pretightning force of bonnet.For example 7 inches of bonnet will meet mud pressure when being 1060000N, according to the structure of bonnet, conversion
To the moment of torsion applied to bonnet, screw bonnet screw thread application torque and should be 55000Nm, bonnet screw thread is unscrewed using a period of time
Moment of torsion it is higher, it is necessary to 59000Nm.Therefore the moment of torsion that bonnet is subject to is especially big.
Bonnet most commonly used at present is shown in Fig. 9, and bonnet is applied and only leans on through hole around bonnet axis rotation torque
（1c）, the problem of this structure is present：Very bad quantitative application torque value；It is extremely difficult to apply super-huge torque, such as will
Apply foregoing 59000Nm super-huge torque, it is necessary to applying 780000N on the mean radius 75mm of the hole.Exactly because there is this
The deficiency of sample, the bonnet of present high pressure slurry pump use structure extremely complex without using the bonnet of this simple structure
Structure, and use height to 160MPa hydraulic structure to meet the compression of bonnet.
The patent of invention that on October 14th, 2015 announces《A kind of drilling pump cylinder cap assembly tool component》Although can solve
The application torque value quantitative to bonnet, but the function of applying super-huge torque value to bonnet can not be met, because applying super-huge torque
During value, the structure will be destroyed.
Therefore invent a kind of bonnet dismantling device for quantitatively applying super-huge torque and become very necessary work.
