Abstract
The utility model provides an anti-abrasion device to prevent the abrasion of an oil pumping unit polished rod and a root, which consists of cylinders, stable brackets and stable bearings. The inner side of the cylinders is provided with rectangle grooves which are distributed on the upper layer and the lower layer evenly, the outside of the rectangle grooves are provided with round holes with threads. Proper screws are arranged inside the round holes; the inner of the rectangles have the proper rectangle stable brackets .The stable bearings are arranged at one side of the stable bracket which is next to the oil pumping unit rod, adjusting the screws can enable close contact between the stable bearings on the top of two rows of the rectangle stable brackets in the cylinder and the oil pumping unit polished rod, so as to effectively protect the polished rod and root and control oil leakage.
Description
Invention field
The utility model relates to the industrial oil-extractor polish-rod sealer of a kind of petroleum recovering, especially relates to a kind of shoe that prevents oil-extractor polish-rod, packing wearing and tearing.
Background technology
At present, the oil-extractor polish-rod sealer directly uses packing in petroleum recovering industry, polished rod packing more easy to wear, be ground to packing box again behind the polished rod wear disc root when serious, make the polished rod that is worth costliness impaired, both caused oil accident, be subjected to serious economic loss again.Current, still there is not the abrasionproof of use equipment case in the oil-extractor polish-rod sealer.
Summary of the invention
The purpose of this utility model provides a kind of shoe that prevents oil-extractor polish-rod, packing wearing and tearing; it places in the oil-extractor polish-rod sealer; prevent oil-extractor polish-rod wearing and tearing packing and be ground to packing box, both controlled the generation of oil accident, effectively protected polished rod and packing again.
The technical solution of the utility model: a kind of oil-extractor polish-rod that prevents, the shoe of packing wearing and tearing is by cylinder, center rest and stable bearing constitute, cylinder interior is provided with the uniform rectangular channel of two-layer distribution up and down, the outside of rectangular channel is provided with threaded circular hole, the screw rod that coincide with it is installed in the circular hole, be furnished with the rectangle center rest that coincide with it in the rectangular channel, near oil-extractor polish-rod one side stable bearing is housed at center rest, by regulating the screw rod in the outer mother rib lateral rotundum of rectangular channel, the stable bearings on the interior two row's rectangle center rests of cylinder are closely contacted with oil-extractor polish-rod.
Beneficial effect: because the utility model can make and be positioned at its inboard stable bearing and closely contact with oil-extractor polish-rod, thereby protected polished rod and packing effectively, controlled the generation of oil accident.
