Abstract
The utility model relates to a compressor, particularly to a novel rich gas compressor having a sealing function. The rich gas compressor comprises a crank, a compressor shell, a gland and an end gland are sequentially arranged on the crank from left to right, and fillers are filled in the compressor shell. The rich gas compressor is characterized in that a nitrogen inlet is arranged at the upper end of the gland, a nitrogen outlet is arranged at the lower end, a nitrogen channel corresponding to the nitrogen inlet and the nitrogen outlet is arranged in the fillers, an oil scraper ring is arranged between the gland and the end gland, and a seal ring of the gas compressor is arranged between the crank and the fillers. The structure of the compressor is unique, the replacement frequency of lubricating oil and the maintenance rate of the machine set are reduced, and the production cost is greatly reduced. The compressor can improve throttling effect and prolong the use period of the lubricating oil.
Description
Technical field
The utility model relates to a kind of compressor, especially relates to a kind of rich gas compressor with novel seal effect.
Background technique
At present, in the compressor high pressure cylinder, filler is the slit that is used between sealing cylinder and the piston rod, prevents the parts of gas leakage.In device was produced, it be the task of absorbing-stabilizing system compression rich gas that gas compressor is being undertaken, and in actual production, the unit continuous operation time is long, and the packing seal wearing and tearing cause unit poorly sealed, level with grade among gas or condensed oil scurry mutually or flow backwards.Because sealing and between centers crack are excessive, rich gas or condensed oil will be scurried in the unit crankcase, cause the interior quality of lubrication oil of crankcase seriously to descend, cause lubricating oil pressure low, mechanical admixture exceeds standard, and makes that lubricant oil is too fast to lose original performance index, need a large amount of the replacing, cause cost to increase.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of structure uniqueness is provided, has reduced the replacing frequency of lubricant oil, reduced the maintenance rate of unit, saved a large amount of cost of production, can improve restriction effect, prolonged a kind of rich gas compressor of lubricant oil life cycle with novel seal effect.
The utility model is realized in the following way:
A kind of rich gas compressor with novel seal effect, comprise bent axle, be combined with compressor housing, gland and end gland on the bent axle from left to right successively, be filled with filler in the compressor housing, it is characterized in that: the upper end at above-mentioned gland is provided with nitrogen inlet, the lower end is provided with nitrogen outlet, in filler, be provided with and above-mentioned nitrogen inlet and the corresponding channel of nitrogen of nitrogen outlet, between gland and end gland, be provided with scraper ring, between bent axle and filler, be provided with the aerostatic press seal ring;
Described aerostatic press seal ring is provided with six groups along described bent axle.
The utility model has following effect:
1) structure uniqueness: the device that the utility model provides comprises bent axle, be combined with compressor housing, gland and end gland on the bent axle from left to right successively, be filled with filler in the compressor housing, it is characterized in that: the upper end at above-mentioned gland is provided with nitrogen inlet, the lower end is provided with nitrogen outlet, in filler, be provided with and above-mentioned nitrogen inlet and the corresponding channel of nitrogen of nitrogen outlet, between gland and end gland, be provided with scraper ring, between bent axle and filler, be provided with the aerostatic press seal ring.
2) device that provides of the utility model leaves nitrogen inlet and outlet at the compressor packing box, in the aerostatic press filler, leave channel of nitrogen, feed nitrogen during unit operation, in addition, the aerostatic press seal ring can prevent that also the rich gas condensed oil from scurrying in the unit crankcase, the contaminated dilution of lubricant oil in the crankcase, mechanical admixture exceeds standard, thereby quality of lubrication oil is seriously descended, lost original performance index, need to change in a large number.Be provided with scraper ring at gland and end between the gland, institute's lubricant oil of being with collection on the bent axle can be got back in the crankcase recycling after filtering by scraper ring.
3) can improve restriction effect, prolong the lubricant oil life cycle: the device that the utility model provides feeds in new sealing and adapts to the inert gas that is higher than unit compression cylinder pressure, certainly press sky by itself again, use nitrogen-sealed to solve the problem of above existence effectively, neither influence the safe operation of unit, guaranteed quality of lubrication oil again, contrast by practice test, quality of lubrication oil is greatly improved than before, reduced the replacing frequency of lubricant oil, reduce the maintenance rate of unit, saved a large amount of cost of production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of rich gas compressor with novel seal effect, comprise bent axle 10, be combined with compressor housing 9, gland 5 and end gland 6 on the bent axle 10 from left to right successively, be filled with filler 2 in the compressor housing 9, as shown in Figure 1: be provided with nitrogen inlet 1 in the upper end of above-mentioned gland 5, the lower end is provided with nitrogen outlet 7, in filler 2, be provided with and above-mentioned nitrogen inlet 1 and nitrogen outlet 7 corresponding channel of nitrogen 11, between gland 5 and end gland 6, be provided with scraper ring 4, between bent axle 10 and filler 2, be provided with aerostatic press seal ring 3.
Above-mentioned aerostatic press seal ring 3 is provided with six groups along described bent axle 10.
The utility model leaves nitrogen inlet 1 and outlet 7 at the compressor packing box, in aerostatic press filler 2, leave channel of nitrogen, feed nitrogen during unit operation, in addition, aerostatic press seal ring 3 can prevent that also the rich gas condensed oil from scurrying in the unit crankcase, the contaminated dilution of lubricant oil in the crankcase, mechanical admixture exceeds standard, thereby quality of lubrication oil is seriously descended, lost original performance index, need to change in a large number.Between gland 5 and gland 6, be provided with scraper ring 4, by scraper ring can with on the bent axle the lubricant oil of being with collect, get back in the crankcase recycling after filtering.
For pressure height, inflammable and explosive or toxic and harmful, can in the middle of stuffing box packing, feed the nitrogen that pressure is higher than gas pressure 0.05MPa.
