Description
Technical Field
The utility model relates to a compressor, concretely relates to be applied to vertical reciprocating compressor's frizing filler.
Background
The vertical reciprocating compressor is a medium and small reciprocating compressor which is commonly used all the time, and compared with a horizontal reciprocating compressor, the vertical reciprocating compressor has the advantages that the occupied area is small, the arrangement of multiple rows is not influenced by reciprocating balance force, but the gravity center of the vertical reciprocating compressor is higher, the vibration of the compressor is difficult to control, so that a filler arranged on a piston rod is easy to leak, particularly an oil scraping filler, medium and environment pollution is caused due to the leakage of lubricating oil, and a large amount of lubricating oil is wasted.
Therefore, there is a need for an improved oil scraping packing structure of a vertical reciprocating compressor.
Disclosure of Invention
The invention aims at providing an oil scraping filler of a vertical compressor, which improves the oil scraping effect with a simple structure and ensures the sealing of the side gas of a cylinder.
In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows: the utility model provides a vertical compressor's frizing is packed, includes the packing box, at the opening side fixedly connected with flange joint structure of packing box, flange joint structure is close to packing box one side periphery and is equipped with O type circle, be equipped with the frizing ring subassembly in the packing box, the frizing ring subassembly comprises first ring, second ring and third ring in proper order, it has a plurality of draining grooves to distribute on the side that first ring and second ring are adjacent, and the interior rampart of first ring is at the increase of neighbouring second ring department internal diameter, constitutes the face of scraping oil, lateral clearance has between second ring and first ring, and the cooperation constitutes the frizing structure, the third ring is the gas seal ring.
According to the further technical scheme, an inner diameter groove is formed in the inner diameter of the second ring, and a radial hole is communicated with the inner diameter groove.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
1. the oil scraping filler is integrally fixed in a structure through the matching of the filler box and the flange connecting structure, on one hand, the oil scraping filler is convenient to install, and on the other hand, the oil scraping ring can stably scrape oil on the piston rod when the piston rod passes through the oil scraping ring;
2. the utility model discloses a scraper ring part comprises three ring, and wherein the cooperation of first ring and second ring realizes the frizing, and second ring and third ring play sealed effect simultaneously, and with the cooperation of the packing box, realize the sealing to cylinder side gas, prevent that cylinder side gas from getting into the fuselage and polluting lubricating oil.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is an enlarged view of a portion of the scraper ring component of fig. 1.
Wherein: 1. a stuffing box; 2. a flange connection structure; 3. an O-shaped ring; 4. a scraper ring assembly; 5. a first ring; 6. a second ring; 7. a third ring; 8. scraping the oil surface; 9. an oil drainage groove; 10. an inner diameter groove; 11. a radial bore.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
the first embodiment is as follows: referring to fig. 1, the oil scraping packing of a vertical compressor comprises a packing box 1, wherein a flange connecting structure 2 is fixedly connected to the opening side of the packing box 1, an O-ring 3 is arranged on the periphery of the flange connecting structure 2 close to one side of the packing box, and an oil scraping ring assembly 4 is arranged in the packing box 1.
In this embodiment, the stuffing box 1 is used for installing an oil scraper ring, and is simultaneously matched with the oil scraper ring to realize the sealing of the gas on the cylinder side.
The flange connecting structure 2 is used for integrally fixing the oil scraping filler in a structure, and ensures that when the piston rod passes through the oil scraping ring, the oil scraping ring can stably scrape oil on the piston rod.
The O-shaped ring 3 seals the inner side and the outer side of the oil scraping filler, ensures that gas on the cylinder side does not enter the machine body, and also ensures that oil on the machine body side does not enter the cylinder side through the surface.
Referring to fig. 2, the oil scraper ring assembly 4 is sequentially composed of a first ring 5, a second ring 6 and a third ring 7, a plurality of oil drainage grooves 9 are distributed on the side surfaces of the first ring 5 adjacent to the second ring 6, the inner diameter of the inner ring wall of the first ring 5 is increased at the position adjacent to the second ring 6 to form an oil scraping surface 8, a lateral gap is formed between the second ring 6 and the first ring 5 to form an oil scraping structure in a matching mode, and the third ring 7 is a gas sealing ring. Wherein, the second ring 6 is provided with an inner diameter groove 10 at the inner diameter, and the inner diameter groove 10 is communicated with a radial hole 11.
The main function of the oil scraper ring assembly 4 is to scrape the lubricating oil on the piston rod through the oil scraping surface, then to guide the oil out of the oil scraper ring through the oil drainage groove, so that the lubricating oil is ensured not to enter the cylinder side along with the piston rod to cause medium and environmental pollution, and the waste of a large amount of lubricating oil is avoided. Meanwhile, the second ring and the third ring form a sealing ring which can be matched with a packing box to seal the air on the cylinder side, so that the air on the cylinder side is prevented from entering the machine body to pollute lubricating oil, and the air on the cylinder side is also prevented from entering the atmosphere through the machine body, thereby causing more serious pollution and danger.
