The gland for be set in pressure cap that packing covers, abutting against with packing and pressure cap respectively, the handle being arranged on pressure cap.Using this
The polish rod seal device of kind structure does not have lubricating function.Therefore in order to which the lubrication ensured between polished rod and packing can only stop taking out
The operation of oil machine, frequently the coating lubricating oil fat on the polished rod at polish rod seal device.It is done so that it is not only time consuming,
And the poor effect of lubrication.Lubricant grease is unable to reach the position that packing is combined with polished rod, so as to cause polished rod to exist with packing
Direct friction is produced in the case of lacking lubricant grease, causes packing damage frequent, and then influence oil well production.
The content of the invention
In order to overcome the drawbacks described above of the prior art, the technical problems to be solved by the invention there is provided a kind of infiltrative type
Polish rod seal device, it can ensure that the normal of oil well produces and extend the service life of packing, and need not often add profit
Lubricating oil.
The present invention concrete technical scheme be：
A kind of infiltrative type polish rod seal device, the infiltrative type polish rod seal device include be set on polished rod packing, be set in
Packing lid on the packing, the pressure cap for being set on polished rod and being fixedly connected with the top of the packing lid, be set on polished rod
And the gland abutted against respectively with the pressure cap and the packing, and the handle being arranged on pressure cap；
The infiltrative type polish rod seal device further includes a fuel tank being set in outside the pressure cap, and the polished rod, handle run through
The fuel tank, the polished rod by polished rod seal part with the fuel tank is closed is flexibly connected；The handle passes through handle seal
With the fuel tank is closed is fixedly connected；The fuel tank is fixedly connected with the pressure cap by the way that pressure cap seal is closed；
The fuel tank is detachable member, is fixed by two halves oil box by linking crack structure.
In above-mentioned infiltrative type polish rod seal device, the shape of fuel tank can be determined according to actual needs, its volume
And.The link crack structure refers to be tightly connected the oil box of two halves using silica gel, and silicon is being cut open when not used to facilitate
Glue, convenient dismounting.
In above-mentioned infiltrative type polish rod seal device, it is preferred that a tank filler sleeve is also set up on the fuel tank.
In above-mentioned infiltrative type polish rod seal device, it is preferred that be provided with sealing between the pressure cap and the packing lid
Circle, the sealing ring are arranged on the lower part of the pressure cap.
In above-mentioned infiltrative type polish rod seal device, fuel tank can fill oil, can not also fill, according to actual needs,
Preferably, the infiltrative type polish rod seal device further includes an oil well pump and jet pipe, and the oil well pump is arranged on the fuel tank
Bottom, the jet pipe is fixedly connected with the oil well pump, and the oil outlet of the jet pipe is arranged on the pressure cap and the polished rod
Joining place.
Infiltrative type polish rod seal device in the present invention can be under non-stop-machine state, can be constantly to polished rod and packing
Between be lubricated, it is ensured that polished rod and packing will not produce dry friction, while also so that packing is constantly in preferably work shape
State, improves the production efficiency of oil well, extends the working life of packing, avoids the waste of packing.And the setting of fuel tank can
To ensure not having to add lubricating oil again for a long time, production efficiency is equally improved, reduces person works' amount.
