Description

The external brake formula laterally compensates packing box automatically

Technical field

The utility model relates to the oil field extracting device of oil, belongs to the improvement of wellhead polish rod sealed packing box, and particularly the external brake formula laterally compensates packing box automatically.

Background technology

The present wellhead polish rod sealed packing box that uses does not design gate, when changing the sealing original paper, need efflux crude oil in a large number, and change after the step-down when sealing original paper, and ground crude oil needs to reclaim.In the course of the work, there is the run, drip, leak phenomenon mostly in the sealing packing box, especially super heavy oil wells, the temperature height, fuel-displaced undesired, the wearing and tearing of polished rod fever apron, itself not have the function of in time replenishing encapsulant, common rubber packing replacing frequently, oil leakage phenomenon is more serious.

Summary of the invention

The purpose of this utility model is to provide a kind of external brake formula laterally to compensate packing box automatically, under the situation of not stopping oil pumper, can be in the well head packing box horizontal automatic compensation sealing filler, and during the automatic compensation sealing filler, can make the well head sealing, crude oil is not revealed, and is simple to operate, working service is convenient, reduces labor strength.

The utility model is achieved in that a kind of external brake formula laterally compensates packing box automatically, the through hole of tubular pedestal bottom matches with polished rod, conical internal cavity on pedestal top is installed with the whole packing that matches with polished rod, the outer wall suitable for reading of pedestal is being installed with pressure cap by screw thread, between pressure cap and whole packing, briquetting is installed, on the sleeve pipe of pressure cap end face through hole setting, little pressure cap is installed by screw thread, in the groove that taper groove that is provided with and polished rod constitute metal packing is installed on sleeve pipe inwall suitable for reading, on the symmetrical charging side opening of pedestal filler chamber wall setting, connecting the feed pipe that the outer end has automatic propelling filler device by fixing stuffing seal respectively, the deviation correcting device that matches with polished rod is being set in the bottom of pedestal.

The utility model is installed, and when polished rod and well head misaligned, the correction linkage of logical pedestal bottom was rectified a deviation, make polished rod and well head centering after, linkage is connected with well head by rectifying a deviation.In the oil pumper course of work, in filler chamber and feeding cylinder, fill filler, the automatic propelling filler device of installing in feed pipe after the filler wearing and tearing advances the filler in the feed pipe to fill in filler chamber automatically, does not influence the operate as normal of oil pumper.When needs in feed pipe during additional fillers, do not stop oil pumper, only need to operate the fixedly stuffing seal that connects on the pedestal filler chamber wall symmetry charging side opening, sealing well head, crude oil is not outwards revealed, by the drill autofeeder on the feed pipe sealing well head is added in airtight and watertight padding fast then.After the utility model has been installed, adds airtight and watertight padding and do not stop oil pumper, do not need crude oil is discharged to the pond outward, and the steam coach that cancellation pump truck, the oily car of receipts and winter use reclaims ground crude oil to the pond.Reduced the waste of manpower and materials.The utility model is simple to operate, and working service is convenient, has reduced working strength of workers.
