Description
Technical field
The utility model belongs to oilfield development equipment field, is specifically related to a kind of pumping unit and concentrates grease filler.
Background technique
The important component part of pumping unit through-stone oil equipment, beam pumping unit uses existing nearly 70 years history in China, any variation does not occur by connecting rod with the reciprocating basic structure that rotatablely moving of motor becomes oil well pump in it, its four pairs of bearings, namely axis, tailing axle and crank pin bearing do not have large variation yet.Axis, tailing axle are done oscillating motion, and the crank pin bearing rotates, and these several bearing rotating speeds are very low, only have≤10 turn or inferior/minute, but rated load reaches 8 tons, and its load character is the alternation low-speed heave-load, often occurs causing the bearing premature wear, biting even stuck phenomenon because of insufficient lubrication.
At present, each bearing grease injection lubricating method of above-mentioned beam pumping unit mainly is divided into two kinds: the first system adopts manually smears lubricating grease; The second system adopts the grease gun greasing.Every 6 months the lubricating grease of pumping unit is changed once.Above-mentioned which kind of injecting grease for lubricating method no matter must shutdown of pumping machine when changing lubricating grease.
If adopt and manually smear lubricating grease, get first the bearing cap of above-mentioned bearing is opened, by artificial old bearing grease is dug out, coat new bearing grease, bearing cap is loaded onto.Although this method is simple, can't there be the old lubricating grease of a large amount of metal mill nights and aged deterioration thoroughly to clear out with remaining between roller, raceway, grid frame in the bearing.Owing to being subjected to structural limitations, when maintenance, bearing can not being taken off and clean; Simultaneously, the new lubricating grease that is stored in Zhou Cheng Grains and the bearing cap can not be to replenishing between roller and raceway.Remaining old lubricating grease will accelerate bearing wear, makes damage of bearings, and may cause pumping unit connecting bar to fracture, and frame is forgotten about it, and stops production, even can cause casualty accident.
In bearing, annotate lubricating grease if adopt grease gun, when annotating lubricating grease, in each bearing of pumping unit, annotate lubricating grease with grease gun, when concrete operation, because consistency of grease is very large, when annotating lubricating grease, lubricating grease often is extruded near the pump nozzle of bearing, away from annotating the lubricating grease of not entering in the bearing of pump nozzle, so that a part has lubricating grease in the bearing, the old lubricating grease of another part can not be extruded, and new lubricating grease can not be injected into, and does not have new lubricating grease, bearing can not be lubricated well, lubricating grease is the same with manually smearing, and same the existence accelerated bearing wear, makes damage of bearings, cause the connecting rod of pumping unit to fracture, frame is forgotten about it, and stops production, even can cause casualty accident.
Fully injection and the dirty lubricating grease of the new lubricating grease that the technical problem that current beam pumping unit need to solve is bearing are thoroughly discharged, to improve the working life of beam pumping unit bearing, improve the serviceability rate of pumping unit, increase oil recovery amount not changing in the integrally-built situation of pumping unit.
