Description

The automatic grease lubrication device of pumping unit
Technical field
The utility model relates to a kind of lubricating fitting, is specifically related to the automatic grease lubrication device of a kind of pumping unit.
Background technique
From between 200 coming year that beam pumping unit comes out so far, the rotary motion of motor is become the reciprocating basic structure of oil well pump by connecting rod and any change greatly does not occur by it, and its four pairs of bearings and axis, tailing axle and crank Xiao bearing are also without large change.For CYJY8-2.5-26HB type pumping unit, in these four pairs of kinematic pairs, axis and shaft bearing do oscillating motion, and crank Xiao bearing rotates, and speed extremely low (being less than 10 beats/min, 10 revs/min), but rated load reaches 8 tons.The load character of these four pairs of kinematic pairs is typical alternation low-speed heave-load.This structure, very easily cause the wearing and tearing of bearing because bearing lubrication is bad, bite even stuck.Current pumping unit four pairs of bearings adopt the maintenance method of the following two kinds conventional lubrication, and its Problems existing is also many.
1, lubricating method is smeared: namely shut down every about 3-6 month and taken apart by the bearing cap at above-mentioned 4 bearing places, manually dug out by old fat and be coated with new fat, lubricating maintenance end-of-job after dress is multiple.Though the method is simple and easy to do, significantly defect is exactly the dirty fat containing a large amount of metal filings and aged deterioration remaining between bearing roller, raceway, gratings thoroughly cannot be removed.Due to structural limitations, we can not take off bearing cleaning, simultaneously again because the low speed worst cold case at these positions and the use No. 3 high-consistency lubricating grease that dispatch from the factory, thus the good grease making bearing hub and Gai Nei store can not supplement to roller, the flowing of raceway place, in the course of time, remaining dirty fat will inevitably accelerate bearing wear until damage.We break by pumping unit connecting bar run at ordinary times, shelf forget about it partly cause be exactly due to bearing lubrication bad caused by.And above-mentioned phenomenon refers to the problem that occurs when still can do conventional lubrication maintenance operation to pumping unit bearing; If be late for maintenance or can only carry out at scene in the wild due to lubrication operation, fill the secondary pollution that new lubricating grease is subject to dust in environment, the grains of sand unavoidably, this problem will be more outstanding.
2, grease gun greasing method: shut down rear grease gun and fill fat till the dirty seborrhea in shaft seal place goes out to each bearing within above-mentioned interval.Than manual semar technique, the dirty fat at part roller, raceway, gratings place can thoroughly be removed by this method.Deficiency is exactly under the effect of grease gun pressure, and new fat with pressure is only walked the minimum path of resistance and directly gone from shaft seal is excessive, and all dirty fat be in this path can move forward direct spilling under pressure promotes; All the other 90% dirty fat be not in this passage then can still stay original place and can not renew, so this method equally exists no thoroughness with semar technique, its effect is also same.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides the automatic grease lubrication device of a kind of pumping unit.
The technological scheme that the utility model is taked is: the automatic grease lubrication device of a kind of pumping unit, it comprises greasing pump, for controlling the controller of described greasing pump running, for storing grease tank and the oil separator of grease, described greasing pump is connected with controller and is arranged on grease tank, described stuffing delivery side of pump connects one end of the first oil inlet pipe, the other end of the first oil inlet pipe is provided with quick release coupling assembly, described oil separator is provided with a filler opening and several oil outlets, the filler opening of described oil separator is connected with one end of the second oil inlet pipe, the other end of the second oil inlet pipe is provided with quick release coupling assembly, described first oil inlet pipe realizes being connected fast by described quick release coupling assembly with the second oil inlet pipe, the oil outlet of described oil separator is connected to the bearing place treating stuffing respectively by oil outlet tube.

Described grease tank is positioned on packaged type dolly.
Described air compressor is arranged on bottom and is equipped with on the base plate of universal wheels.
Described greasing pump is provided with revolution counter.
Grease filter is provided with between described second oil inlet pipe and quick release coupling assembly.
The oil outlet quantity of described oil separator is 4 or 6.
Described first oil inlet pipe is multi-layer high-voltage oil pipe, and described second oil inlet pipe is polyurethane flexible pipe.
Described oil outlet tube one end connects the oil outlet of oil separator, and the other end is provided with swivel joint, and described swivel joint is connected with the connection mouth be located on bearing cap.
The beneficial effects of the utility model are as follows:
(1) people-oriented and the requirement of HSE system management to meet oil play.Lubricating maintenance work is safer, does not need workman to climb and carries out lubricating maintenance operation in the air at 4-5 rice, when fundamentally having stopped lubricating maintenance the person fall in the air, the generation of the major accident such as extruding.For desert high temperature or spring strong wind, the area of people's numbness in hands and feet that winter, cold caused is especially applicable, security risk can be dropped to minimum.
(2) lubrication is clean, thorough.Because lubricating maintenance operation carries out under pumping unit working state, thus when new fat with pressure enters from bearing cap side, bearing is in rolling working state, now, so-called " mill effect " is fairly obvious, namely new fat with pressure can by the dirty fat of (roller, raceway, gratings) between all moving surfaces one by one and final all replace after flow out from opposite side, thus lubricate clean especially, thoroughly.Just because the lubrication state of roller, raceway is obtaining very big improvement after this measure, be equivalent to add new fat again to by the bearing thoroughly cleaned up, therefore, substantially prolongs the working life of pumping unit vital part, reduce the user cost of pumping unit.(mill effect and stone mill when grinding bubble grain, evenly flowing out until the phenomenon flow to end from mill junction plane gap surrounding after grain enters from spout).
(3) do not shut down and carry out lubricating maintenance operation, easy to operate, be equivalent to improve rate when oil well drives a well.Its superiority more aobvious and advance for high-yield well and intensive well in blocks and production task unit heavily, can solve the contradiction between production with equipment maintenance preferably.
(4) because centralized lubrication device is full closed, greasing pump (motor-drive pump, pneumatic pump or hand pump) is connected with quick release coupling greasing mouth through flexible pipe, therefore, lubrication work is not by any external action, no matter wind outside, sand, rain, snow, condition is severe again, all can guarantee the clean of lubrication operation.
(5) raise labour efficiency, reduce labor intensity.Traditionally carry out lubricating maintenance operation, two people one group shut down operation of climbing, and a pumping unit lubricating maintenance about needs three ~ tetra-hours; And after installing centralized lubrication device, overall process only needed about half an hour, improve work efficiency more than 10 times.
(6) more green, environmental protection more.Manually smear or grease gun greasing, the dirty fat that the places such as roller, raceway, gratings should remove does not come out, and remain in bearing hub, cover still unmetamorphosed clean fat and dug up, hand and instrument and pumping unit are stained with grease simultaneously, work extremely inconvenient and pollute equipment and environment.
