Abstract
The utility model discloses a water-cooling single screw compressor, comprising a screw mechanism and star wheel mechanisms which are meshed each other. The star wheel mechanisms are two sets which are vertically and respectively arranged at the left side and the right side of the screw mechanism in a forward and reverse mode; compressed gas in a compression cavity formed by a screw and a star wheel is cooled by cooling water and during the process, mechanical sealing and labyrinth sealing are used for sealing a screw shaft and a bracket shaft of the star wheel mechanism, thus avoiding the cooling water from leaking on a bearing. The lower part of the left side of the left star wheel mechanism and the upper part of the right star wheel mechanism carry out compression to the bearing at the position by adjusting the screw and a pressure cover and generate proper pretightening force to the bearing; and simultaneously, a front bearing seat and a rear bearing seat of the screw mechanism and a left lower bearing seat and a right lower bearing seat of the star wheel mechanism are respectively provided with a drainage channel which can drain the cooling water leaked by the mechanical sealing or the labyrinth sealing. The water-cooling single screw compressor can adjust the height position of the star wheel mechanism randomly; the adjustment is convenient and efficient; the bearing has long service life; and the water-cooling single screw compressor has the advantage of protecting the system.
Description
Technical field
The utility model relates to a kind of gas compressor, is a kind of water-cooled single screw compressor specifically.
Background technique
In existing domestic single screw compressor industry, do not have the single screw compressor of water-cooled pattern as yet.The applicant is through studying test for a long period of time, successfully manufacture experimently out the single screw compressor of water-cooled pattern, the pattern that adopts water that pressurized gas in the compression chamber of formations such as screw mechanism and star-wheel is cooled off, its single screw compressor of having broken away from prior art all is the pattern that adopts fluid that pressurized gas in the compression chamber of formations such as screw mechanism and star-wheel is cooled off all the time, in the long run, it has exempted the replacing cooling oil, it is low to have cost of production, the advantage of environmental protection meets the requirement of modern production.Yet, the water-cooled single screw compressor that trial-production is come out, it mainly utilizes mechanical seal and labyrinth seal with screw axis, the bracket axle of star-wheel mechanism seals, avoid cooling water to leak on the bearing, the remaining part structure still remains to be improved, for example: in the star-wheel mechanism of compressor (this mechanism is generally vertical installation), as shown in Figure 1, the outer ring of the direct block bearing of bearing (ball) cover of bracket axle below, when need are adjusted the height of star-wheel, must the dismounting bearing (ball) cover, and between itself and bearing, place the pad of suitable thickness or the height of match grinding bearing (ball) cover, trouble very; Secondly, because the outer ring of the direct block bearing of bearing (ball) cover of carriage below, when carriage need move up and down the adjustment height, the location end face of guaranteeing this bearing (ball) cover contacts with the cycle surface of bearing and has a pretightening force, for this reason, make the bracket axle top must apply the bigger pretightening force that presses down, and the pretightening force that presses down of bracket axle top can only be by the spring of big elastic force, this spring is generally taked the cylindrical spring of length, cause the bearing (ball) cover inner spring installing space of bracket axle top excessive, and the big elastic force that this spring produces finally drops on the bearing, strengthens the work loads of bearing, can reduce the working life of bearing like this.Again for example: the single screw compressor of this water-cooled pattern; when running into mechanical seal and occur leaking; when shutting down or in the start process; cooling water between bearing and the labyrinth can not discharge; water can be accumulated between bearing and the labyrinth; cause in next time start or at the operation process middle (center) bearing and in water, turn round, reduce bearing working life equally, thereby influence the reliability of machine and life-span etc.
