Description
Technical field
The invention belongs to the corollary equipment for the drilling machine that recovers the oil, the vortex for being related to the auxiliary brake of deep sea drill or land rig is stopped
The production technology of vehicle stator module.
Background technique
Vortex brake is used as the auxiliary brake of deep sea drill or land rig, both also can be able to be mine with winch supply in full sets
The drilling machine that has used of field is mating supplied as separate part its working principles are as follows:
It is vertical with magnetic direction in this conductor when the iron magnetizer of a movement passes through a fixed non-uniform magnetic field
Plane on induct a loop current, be referred to as vortexed, this vortex will cause a magnetic field, and the polarity in this magnetic field is just solid with original
The polarity of fixed-field is on the contrary, two opposite polarity magnetic fields move conductor is revolted in magnetic field, and here it is vortex brakes
Working principle.The necessary condition for generating vortex and counter magnetic field is that iron conductor moves in fixed magnetic field, so when iron conductor is kept
Stationary state will induct without vortex, and the rotor of vortex brake is exactly iron conductor, and the coil for generating fixed magnetic field is mounted on stator,
Rotor and stator form the basic structure that an air-gap is configured to brake.Rotor is forced to turn by winch drum while coil magnetization
Dynamic, rotor just produces the moment of resistance of resistance movement.
Vortex will cause a large amount of heat in rotor inner surface during vortex brake works, these thermal energy are by passing through rotor surface
Cooling water carry away, cooling water is in the liquid level kept certain height of brake inner cavity, whole rotor surfaces when the rotor rotates
It can be transferred through cooling water, to prevent the danger of overheat.According to vortex brake structural behaviour feature, stator interior must be protected
It demonstrate,proves hermetically sealed (i.e. coil must not be contacted with water, guarantee the performance of coil), stator body structure is welding structure, mainly group
It is casting at part material.In original subassembly technique, it need to show and welded seam is detected, guarantee that it reaches waterproof and wants
It asks.And need to detect weld seam is continuous annular fillet weld, structure space is small, and the detection means such as ultrasonic examination, magnetic powder inspection are equal
It is not applicable, therefore the method for hermeticity experiment is selected to examine.During doing air-tight test, tooling need to be used to seal stator
Extremely make internal formation hermetic type chamber, is put into soaking in water tank, while sky is suppressed to stator type is intracavitary by tracheae and tooling interface
Gas, observation judge leak source.Air seal test is carried out again after tooling is removed repairing weld seam after judgement, until ne-leakage phenomenon.And
For such method there are multiple problems, 1. material of main parts are casting, when suppressing air and entering type chamber, itself stomata of hypertonia casting
It leaks, influences leak source judgement.It can not clearly be any item weldering when observing leak source 2. need to detect weld seam is the parallel weld seam of twice
Seam leakage, influences Repair Parameters.3. this method repeated multiple times need to be tested, time-consuming and laborious effect is poor, and human factor influences big.
The problem causes life cycle of the product long and uncontrollable, and test knot data human factor influence is excessive, and testing result accuracy is poor,
Greatly restrict the quality of product.
Summary of the invention
It is above of the existing technology the invention aims to solve the problems, such as, propose a kind of vortex brake stator module
Seal assembly technique.
The technical solution adopted by the present invention is that: a kind of sealing assembly technique of vortex brake stator module, by stator
Dynode tooth, monopole tooth, the waterproof cover of component carry out a group weldering, and the internal cavity of positioned coil is cleared up after welding, makes internal cavity
Upward, insulating cement is added in stator module internal cavity group welded, and insulating cement is paved with the bottom of internal cavity, with a thickness of 4~
5mm waits insulating cements to be packed into coil when reaching the 70% of complete setting time, then the gap that internal cavity is vacated all is poured into absolutely
Edge glue waits insulating cement to solidify completely；It is packed into right magnetic pole and carries out a group weldering, stator module is rotated into 180 degree, allow original in bottom
The internal cavity set upward, repeats above operation, i.e., internal cavity adds insulating cement, unwrapping wire circle, fills insulating cement again, waits insulation
Glue consolidation；It is packed into left magnetic pole and carries out a group weldering, complete stator assembly.
Preferably: the insulating cement is bi-component addition type silicon gel.
Preferably: the insulating cement is epoxy resin.
The beneficial effects of the present invention are: it is 1, process stabilizing, reliable, reduce the link of cooling system hermeticity experiment, subtracts
Few detection such as reprocesses at the links, replace filling mud plus fills, time saving and energy saving, shortens the delivery date of product and increases the steady of product
It is qualitative；
2, simple process, reaction condition is mild, and low energy consumption；Born pressure medium is not high, and glue-line is thicker, therefore to encapsulating work
Skill is of less demanding, and silicon gel can keep for a long time elasticity within the scope of -60~20 DEG C, therefore process environments temperature is normal work
Make temperature；
3, after silicon gel solidification, Applicable temperature is -50~180 DEG C, and in stable condition, heat conductivity is good, insulation performance
Beneficial, especially suitable for coil filling and protection；
4, raw material is cheap and easy to get, at low cost；This patent process is mainly concerned with silicon gel, specially bi-component
Additional organosilicon gel, market are easily purchased, cheap.

Specific embodiment
A kind of sealing assembly technique of vortex brake stator module, by the dynode tooth 1 of stator module, monopole tooth 4,
Waterproof cover 5 carries out a group weldering, and the internal cavity of positioned coil 3 is cleared up after welding, makes internal cavity 6-2 upward, determines what group welded
Insulating cement is added in sub-component internal cavity 6-2, and insulating cement is paved with the bottom of internal cavity 6-2, with a thickness of 4~5mm, waits insulating cements
It is packed into coil 3 when reaching the 70% of complete setting time, then the gap vacated internal cavity 6-2 is all poured into insulating cement, is waited
Insulating cement solidifies completely；It is packed into right magnetic pole 7 and carries out a group weldering, stator module is rotated into 180 degree, allow originally in the inside of lower position
Type chamber 6-1 upward, is repeated above operation, i.e. internal cavity 6-1 adds insulating cement, unwrapping wire circle 3, fills insulating cement again, waits insulation
Glue consolidation；It is packed into left magnetic pole 2 and carries out a group weldering, complete stator assembly.
Insulating cement used is epoxy resin or bi-component addition type silicon gel (model: GN-521 and GN-522).Have
Machine Silica hydrogel cure shrinkage is smaller, therefore preferable using silicon gel for the product of frequency sensitive.Silicon gel and
The viscosity of epoxy resin is low, good fluidity, it is easier to reach each gap, can closely be encapsulated coil, and solidify
Adhesive elastic afterwards is good, can absorb vibration and shock resistance.Electrical insulation capability, the high and low temperature resistance of silicon gel are better,
And the anti-electric shock intensity of epoxy resin is good, and different glue kinds can be applicable according to different occasions.
