Description
Technical field
The utility model relates to the oil drilling inclinometer, particularly about a kind of wireless drilling electric capacity pipe nipple of high antivibration.
Background technology
The electric capacity pipe nipple is the important component part in the directional tool pulse generator; In order to stored energy; Make the iron core in the excitation component produce the adhesive campaign, the servo spool motion of clamp-pulse generator, and then the motion of control main valve head; Cooperate the generation pressure pulse signal with restrictor ring, reach the effect of sending the pulse signal to the well head pressure transducer.
The tantalum electric capacity of similar products at home and abroad has all adopted the cartridge-type fixed form, and is as shown in Figure 1, in the electric capacity pipe nipple, adopts two plugs 10 that four groups of capacitance group 11 order is clipped in the middle, and pass two plugs 10 and four capacitance group 11 connect fixing with stay bolt.Every group of capacitance group 11 comprises electric capacity housing 12 and six high temperature tantalum electric capacity 13 of an aluminium matter again; Six electric capacity 13 are contained in electric capacity housing 12 and radially are uniformly distributed with in six round holes offering; The end, goes between between weld tabs 14 and electric capacity housing 12 ends through 1213 gluing connecing to outer lead through lead-in wire weld tabs 14.Six electric capacity 13 of every group are parallel connection mutually, also parallel connection between the electric capacity of adjacent set, therefore four groups of totally 24 mutual parallel operations of electric capacity.Because electric capacity 13 will insulate with electric capacity housing 12, each electric capacity outer surface has all been wrapped up in the pi film, has the gap so certainly will cause between electric capacity 13 and the electric capacity housing 12, the solder joint that also just has only two ends of fixed capacity.Because instrument follows drill bit closely in the work progress, so in drilling process, the electric capacity pipe nipple is among the operating mode of high strong vibration for a long time, it is tired that vibration just makes the junction of electric capacity lead-out wire and capacitance body for a long time, and then fracture, thereby the electric capacity pipe nipple was lost efficacy.Owing to be to be connected in parallel, as long as there is a whole set of instrument of a condenser failure just can't operate as normal, trip-out, depot repair is exactly a corollary.So such inefficacy can bring at least several ten thousand to drilling team, the loss of hundreds of thousands at most at every turn.
Summary of the invention
Therefore, for solving the antivibration problem of electric capacity pipe nipple, the purpose of the utility model provides a kind of wireless drilling electric capacity pipe nipple of high antivibration.It adopts the epoxide-resin glue improvement of structure in addition of import, can insulate, and electric capacity is securely fixed in the electric capacity stage body.
For realizing above-mentioned purpose; The utility model is taked following technical scheme: a kind of wireless drilling electric capacity pipe nipple is characterized in that: comprised a stage body, monnolithic case is cylindrical; The centre has hollow; Middle part at stage body is divided by section, is uniformly distributed with vertically on the excircle of each section and offers several circular recesss, adorns a tantalum electric capacity in each circular recess; Between the said stage body of each section; Be provided with the twice winding slot, and the crossed beam trunking that is communicated with the twice winding slot, in each said winding slot, be wound with red copper wire; Red copper in each winding slot is around being connected in parallel, and the lead-out wire of each said tantalum electric capacity is wrapped in respectively on the red copper wire nearby; Said stage body is the epoxide-resin glue rod, and it is bonding to smear epoxide-resin glue between the contact-making surface of said circular recess and tantalum electric capacity.
On the excircle at said stage body two ends, radially be provided with several roads annular seal groove.
The middle part of said stage body is divided into 2～6 sections.
Every section annular seal groove quantity is 4～6.
Said circular recess is that semicircle, smaller part is one of circular.
The end of said circular recess is a rounding off.
Said in the end of circular recess, and between the gap of tantalum electric capacity, also be filled with the epoxide-resin glue shutoff.
The utility model is owing to take above technical scheme, and it has the following advantages: 1, the utility model is provided with an all-in-one-piece stage body, and all parts are installed on the stage body; Need not be as prior art; Electric capacity is divided into groups, also plug will be set, the stay bolt that also will use connects; The utility model good integrity can guarantee the stability of whole capacitor pipe nipple.2, stage body has been selected the epoxy resin rod of import for use, and the epoxy resin rod is an insulating material, therefore between electric capacity and stage body, does not need to take in addition insulation measures.3, between the contact-making surface of stage body and electric capacity, also directly use epoxide-resin glue bonding; Electric capacity and stage body are integrally formed, and when vibration, whole pipe nipple vibrates; Each electric capacity then can not vibrate separately, thereby has avoided tantalum electric capacity and lead-out wire junction to produce the fatigue fracture phenomenon.4, the utility model utilizes the annular of red copper wire to twine, and has replaced the lead-in wire weld tabs, makes welding more firm more easily.
