Abstract
The utility model discloses an oil-free lubrication compressor efficient cooling packing sealing device which comprises a connecting body provided with an axial packing cavity, wherein multiple groups of packing boxes are arranged in the packing cavity side by side, a packing ring matched with a piston rod in a sealed mode is installed in each packing box, one end of the connecting body is connected with a cylinder body, the other end of the connecting body is fixed through a flange and a gland, communicated cooling liquid channels are formed among the multiple groups of the packing boxes, and two symmetrical sides in the circumferential direction of the connecting body are respectively provided with a cooling liquid inlet and a cooling liquid outlet which are communicated with a cooling liquid channel inlet and a cooling liquid channel outlet. The oil-free lubrication compressor efficient cooling packing sealing device has the advantages that sealing pressure is high, and under the work condition of oil-free lubrication, sealing of a pressure difference up to 15MPa can be achieved; oil injection lubrication is not needed for packing, and pollution cannot be produced for compressed media; packing cooling effects are good, and service life is long; and leaked trace gas is guided out through a gas pumping channel, and the trace gas cannot be leaked to the air to pollute the environment.
Description
Technical field
The utility model relates to compressor seal filler field, and particularly a kind of non-lubricated compressor efficiently cools off stuffing seal.
Background technique
Filler is the main seal element in the compressor operation, in the compression work process of compressor, can stop the pressurized gas in the cylinder to be revealed by piston rod downwards.The good and bad final air displacement and the exhaust pressure that directly influences compressor of packing elements performance is one of vitals of compressor.In order to realize sealing to the lubricated high-purity medium of high voltage oil-free, often need to be provided with many group stuffing boxes, traditional packing elements is at the filling tube outer wall cooling water channel to be set, when stuffing box group number was many, the piston rod heat is difficult to volatilize away, and cooling effect is poor, in addition, existing packing elements lacks the recovering device of revealing gas, and the gas of leakage enters crankcase, not only wastes but also pollute.
The model utility content
The purpose of this utility model is to provide a kind of non-lubricated compressor efficiently to cool off stuffing seal, can improve cooling effect, can reclaim leakage gas again.
The purpose of this utility model is achieved by the following technical programs, a kind of non-lubricated compressor efficiently cools off stuffing seal, comprise the connecting body that has axial packing cavity, be set up in parallel some groups of stuffing boxes in the packing cavity, the packing ring that cooperates with rod seal is housed in the stuffing box, one end of described connecting body is connected with cylinder block, the other end is fixed by flange and gland, it is characterized in that, have the cooling liquid flowing channel of perforation between some groups of stuffing boxes, the circumferential symmetrical both sides of described connecting body are respectively equipped with and the cooling liquid flowing channel import, cooling liquid inlet and cooling liquid outlet that outlet is communicated with.
Described packing ring comprises one group of pressure-reducing ring being loaded in the nearly cylinder block end stuffing box, be loaded on 3～8 groups of main seal rings in the stuffing box of connecting body stage casing and be loaded on one group of leak sealing ring in the cylinder block end connecting body opening stuffing box far away.
Cooling liquid flowing channel is opened between the stuffing box that main seal ring is housed.
Offer the bleed-off passage that is communicated with on described flange and the stuffing box that the leak sealing ring is housed, described bleed-off passage is communicated with the inboard cavity of the stuffing box that the leak sealing ring is housed.
In the center hole of described flange scraper ring is housed, the outer end of scraper ring is fixed by described gland.
By technique scheme as can be seen, the utility model is designed to packing elements the combination of pressure-reducing ring, main seal ring, leak sealing ring and scraper ring, the pressurized gas of coming from cylinder side, at first reduce pressure by pressure-reducing ring, seal by 3～8 groups of main seal rings again after the decompression, thereby reach the more purpose of high sealing effect, the minimum gas that leaks is extracted out by bleed-off passage; The scraper ring of packing elements axle side can stop the lubricant oil attached to piston rod to enter cylinder simultaneously, has guaranteed the cleaning of compressed media; The cooling liquid flowing channel that is provided with on the stuffing box can cool off filler well; This structural design has solved the packing seal and the efficient cooling problem of the lubricated high-purity medium compressor of high voltage oil-free well.Can be widely used in various high pressure, high-purity, forbid having the sealing of the compressed media of oil.
The utility model is compared with existing stuffing box packing parts, has following remarkable advantage:
1. sealing load height, under the oil-free lubrication operating mode, salable pressure difference up to 15MPa;
2. filler need not oil injecting lubricating, can not produce compressed media and pollute;
3. the filler cooling effect is good, longer service life;
4. the minimum gas of Guo Luing is drawn by bleed-off passage, can not leak into befouling environment in the air.
