Abstract

The utility model provides a lubricant filtering device for a refrigerating compressor used for a refrigerator, an air conditioner, etc., which is characterized in that metal particles and dirt in lubricant can be removed when a compressor normally works to always keep the lubricant in the compressor clean. The utility model has the advantages of the reduction of failure, slowing down abrasion, the avoidance of large economic losses, and the extension of service life, and has the functions of filling refrigerant and additionally adding lubricant. The utility model is composed of a conical hole (2) which is arranged in the center of a most concave position of the bottom of a sealing shell (1) of a refrigerating compressor, a welding screw cap (3), a filtering device three-way body (4) (The filtering device three-way body (4) can be directly welded below the conical hole (2).), a filtering tank (5), a magnetic body (6), a cone top screw bolt (7), a sealing screw cap (8), a sealing pad (9), a filling object (10) and a sealing pad (11).

Description

Lubricant purifying device for refrigerating compressor

The present invention relates to refrigerating machine, is a kind of power supply refrigerator, the lubricating oil purifier that enclosed refrigeration compressors such as air-conditioning use.

The compressor that runs up is closed in work in the metal-back, sneaks in the lubricating oil after on-stream being worn away of part rough surface that forms because of manufacturing.To be worn away the metal particle of sneaking in the oil then more and more along with the growth of time, and lubricating oil and metal particle be lubricate compressors simultaneously, has just reduced the function of compressor and has made it to quicken damage; In this simultaneously, the lubricating oil band the insulating motor coil layer that the metal particle has softened under the high speed impact HTHP as the sand throwing machine, quicken it and wear out, break, leak electricity, burn; When the metal particle increases to finite concentration, it will make, and three-way joint forms a large amount of electric leakages in the compressor, causes the operate as normal of hindering and damaging compressor.Loading in mixture high-pressure refrigerant in the compressor of sealing, lubricating oil is dirty more also can't remove it compressor present situation that Here it is when operate as normal.

Purpose of the present invention is exactly: install a lubricating oil purifier for the refrigeration compressor of sealing, make compressor in operate as normal, the metal particle in the lubricating oil, dirt be leached clearly from the compressor lubricant oil of sealed high pressure, all the time allow compressor keep a cleaning, good lubricated working environment, make it to reduce and damage, increase the service life, promote the well-being of mankind.

Concrete structure of the present invention is provided by following examples and accompanying drawing:

Fig. 1 is a refrigeration compressor lubrication cleaner structure profile of the present invention.

A up big and down small conical bore (2) is bored in the most recessed center, compression case (1) bottom, below, hole (2) shell external welding one metal nut (3), what (also can directly cleaner body (4) be welded herein) connected with nut (3) is cleaner body (4) straight pipe upper end, in the pipe of threeway body (4) straight pipe lower end, with screw thread sealing vertex of a cone bolt (7) is installed, manage outer suit closed nut (8), sealing gasket (9) is arranged in the nut (8), filling closure (10); Body (4) is gone up oblique 1 ° of-85 ° of fairlead in middle part and is irritated (5) with the thread connection filtering, sealing pad (11), and filtering is irritated in (5) permanent magnetism body (6) is housed.

It is such implementation: the lubricating oil in the compression case and sneak into metal particle in the oil, dirt rotates at random, after quitting work, slow down gradually rotating speed until transfixion, hyperbaric metal particle in this process, dirt then converges in the most recessed center, bottom automatically, this moment is because the existence of conical bore (2), the metal particle, dirt then sinks to hole (2) automatically and drops in body (4) pore, when freely falling filtering filling (5) passway, because the suction-operated of magnetic (6) and cooperating of inclined hole drop make the metal particle, dirt completely enters in the filling (5) and must not return to compressor again.Therefore, compressor lubricant oil has been realized the filtering effect.The every work of compressor once, when stopping with regard to filtering once; After date when through one will seal vertex of a cone bolt (7) and upwards tighten, just with the pressure oil sealing gland in the compressor in the dust.Can irritate filtering (5) and twist this moment, pours out and fall metal particle, dirt clearly, filtering irritated (5) after cleaning up again and screw on sealing extremely.At this moment vertex of a cone bolt (7) is screwed down again and compress sealing dead fill (10) sealing gasket (9), cleaner can carry out work.

Utilize cleaner can fill refrigerant feeding, lubricating oil, it makes maintenance greatly convenient.

Claims

1, one by refrigeration compressor capsul (1) the bottom conical bore (2) of recessed center and the refrigeration compressor lubrication cleaner of WELD NUTS (3), cleaner threeway body (4) (also (4) directly can be welded in below, hole (2)), filtering jar (5), magnetic (6), vertex of a cone bolt (7), sealing nut (8), sealing gasket (9), fill (10) and sealing gasket (11) formation; It is characterized in that: there is a up big and down small conical bore (2) the most recessed center, compressor seal shell (1) bottom, nut (3) is welded on below, hole (2), cleaner threeway body (4) upper end is connected with nut (3), with screw thread vertex of a cone bolt (7) is installed in the following stomidium, pipe external application thread set sealing nut (8); Sealing gasket (9) is arranged (8); Fill (10); Body (4) is gone up the oblique fairlead in middle part and filtering jar (5) with thread connection, in sealing gasket (11), the filtering jar (5) permanent magnetism body (6) is housed.

2, according to the cleaner threeway body (4) of the described refrigeration compressor lubrication cleaner of claim 1, it is characterized in that: a metal three-way pipe, the sealing conical surface is arranged in suitable for reading, and the end opening and the oblique mouth of pipe have the binding screw thread, and the oblique angle of its oblique fairlead is 1 °-85 °.

3, according to the filtering jar (5) of the described refrigeration compressor lubrication cleaner of claim 1, it is characterized in that: the container of a cavity heavy wall mouth end band connecting thread, its intracavity bottom is equipped with permanent magnetism body (6).
