Abstract

The utility model belongs to the technical field of filtering devices, and particularly relates to a pumping unit reduction gearbox machine oil filtering device. A reduction gearbox of the pumping unit reduction gearbox machine oil filtering device is connected with a gear pump, and the gear pump is connected with one end of a filter through a pipeline. The pumping unit reduction gearbox machine oil filtering device is characterized in that the filter is divided into three chambers of an upper chamber, a middle chamber and a lower chamber, the upper chamber, the middle chamber and the lower chamber are respectively marked as a filtering chamber (I), a filtering chamber (II) and a filtering chamber (III), the other end of the filter is connected with the reduction gearbox, the reduction gearbox, the gear pump and the filter form a closed loop circuit, a filter screen (I) is arranged between the filtering chamber (I)and the filtering chamber (II), and a filter screen (II) is arranged between the filtering chamber (II)and the filtering chamber (III). By adopting the structure, when the pumping unit reduction gearbox machine oil filtering device is used to filter machine oil, impurities of gravel, lubricating grease, rags, broken brocks and tiles and the like can be filtered out from the machine oil, repeated scrapping phenomena caused by axial movement, key rolling, oil leak, tooth ring abrading and the like of a decelerator are avoided, and furthermore the pumping unit reduction gearbox machine oil filtering device facilitates subsequent production management and equipment management.

Description

Oil pumping unit reduction gearbox engine oil filter

Technical field

The utility model belongs to filtrating equipment technical field, is specifically related to a kind of oil pumping unit reduction gearbox engine oil filter.

Background technique

The pumping unit of using in oilfield exploitation at present, its power mostly is motor, and driving mechanism comprises speed reducer, and crank-connecting rod drives walking beam to swing up and down around the hinge of itself and support.In oil recovery process, oil pump speed reducer is the power transmitting deice of pumping unit key, stolen in order to prevent retarder inner engine oil, on liquid level plug on the most retarder of district of a forest-warden, upper cover is welded, the scene of causing cannot check oil, the oil level situation in retarder, the time of make replacing, checking up Engine oil is relatively long, cause that reducer gear is lubricated not in place, lubricant oil is impure many, lubricant oil is clean poor, thereby causes lubrication effect poor, and gear transmission frictional resistance increases, energy consumption increases, and causes gearbox to reduce working life.In use, due to a variety of causes, the lubricant oil in retarder is impure too many, has sandstone, lubricating grease, cloth waste head, brick tile fragment, water etc.Thereby retarder is altered axle, is rolled key, leakage of oil, the circle of grinding one's teeth in sleep, even cause and the fault such as scrap and occur repeatedly, bring many difficulties to production management, equipment control etc.

When finding that engine oil quality is not up to standard, more renew machine oil, but more renew machine oil, both increased a large amount of cost inputs, extended again and stopped the well time, rate while having reduced oil recovery, has affected output.In addition, the recovery of machine oil is processed and has been caused environmental pollution.In field produces, in oil pumping unit reduction gearbox, engine oil quality problem not up to standard is very general and be difficult to solve, give oil well management and and produce and brought very large difficulty, affect oil well production.Therefore need to improve for above-mentioned shortcoming, design a kind of oil pumping unit reduction gearbox engine oil filter.

Summary of the invention

For solving the problems of the technologies described above, it is a kind of simple in structure, easy to use and can effectively to the impurity in machine oil, clear up that the utility model provides, and avoids because retarder is altered axle, rolled key, leakage of oil, the circle of grinding one's teeth in sleep etc. cause scraps phenomenon.

Oil pumping unit reduction gearbox engine oil filter of the present utility model is realized by following technical proposals:

Oil pumping unit reduction gearbox engine oil filter, speed reducer is connected with gear pump, gear pump is connected by pipeline with one end of filter, filter is divided into three Room, upper, middle and lower, described three Room, upper, middle and lower are designated as respectively filter chamber's I, filter chamber's II, filter chamber's III, the other end of filter is connected with speed reducer, and speed reducer, gear pump, filter form a closed-loop path; Between ⅠHe filter chamber, filter chamber II, there is filter screen I, between ⅡHe filter chamber, filter chamber III, have filter screen II.

The aperture of filter screen I is 0.15-0.25mm, and the aperture of described filter screen II is 0.03-0.15mm.

The aperture of filter screen I is 0.18mm, and the aperture of described filter screen II is 0.08mm.

The filtrating equipment that is magnetic on the inwall of filter chamber's II, can adsorb metallics mixing in machine oil etc., reduces further the impurity in machine oil.

There is filter core III inside, filter chamber.

Filter screen I and filter screen II are plastic filter screen or metal screen.

Filter is cylindrical.

Aspect ratio between filter chamber's I, filter chamber's II, filter chamber's III is 1:1:1.

The beneficial effects of the utility model are, adopted the oil pumping unit reduction gearbox engine oil filter of said structure, machine oil is filtered, reduced impurity wherein, sandstone, lubricating grease, cloth waste head, brick tile fragment etc. are leached, avoided retarder to alter axle, rolled key, leakage of oil, the circle of grinding one's teeth in sleep etc. cause scraps repeatedly phenomenon, are convenient to follow-up production management and equipment control.
