Description
Technical field
The utility model relates to a kind of single-screw air compressor, particularly a kind of single-screw air compressor that utilizes water lubrication.
Background technique
The type of the air compressor of use is mainly now: piston type, single-screw air compressor and screw air compressor, and wherein with the advantage that single-screw air compressor is little to shake, noise is low, be easy to safeguard, the life-span is long, obtained promoting the use of widely.Its cardinal principle is to adopt one to have six cylindrical screw rods of spiral fluted, in the bilateral symmetry of screw rod, arranges two star-wheels, has 11 teeth to be engaged in the spiral chute of screw rod on each star-wheel.When air compressor is opened, motor rotates by elastic coupling flexible coupling drive screw, and air enters in main frame by suction port.Screw rod drives star-wheel in casing, around axis separately, to move again and again together.When star-wheel tooth and screw slot do not seal, be suction condition, along with bolt rod driving star-wheel rotates, screw slot and star-wheel tooth contact produce enclosed space.Now star-wheel tooth is to being positioned at the air compressing of screw slot, in order to lubricate, now can spray into lubricant oil, owing to being to be to mix with pressurized air because participating in lubricated machine oil in single-screw air compressor work, pressurized air also will carry out follow-up Oil-gas Separation after producing, and increases burden to follow-up processing.Therefore urgently develop novel reliable single-screw air compressor to solve the problem existing at present.
Model utility content
The purpose of this utility model is to provide a kind of single-screw air compressor that utilizes water lubrication, to alleviate the processing load of follow-up Oil-gas Separation.
The utility model is achieved by the following technical solution: a kind of single-screw air compressor that utilizes water lubrication, comprise casing, in casing, be provided with one and there is spiral fluted screw rod, bilateral symmetry at screw rod is arranged two star-wheels, it is characterized in that: on described casing, be provided with water injection hole, the two ends of screw rod penetrate the connection bearing in the bearing chamber that is arranged on casing avris, and screw rod two ends are provided with labyrinth seal mechanism, and between bearing chamber and labyrinth seal mechanism, space communicates with ambient atmosphere.On the inter-agency casing of high pressure side screw rod and labyrinth seal, there is by-pass to communicate with low voltage side.Described star-wheel is arranged on central shaft, and the connection bearing of the bearing chamber that is positioned at casing avris is worn at the two ends of central shaft, and central shaft two ends are provided with labyrinth seal mechanism, and between bearing chamber and labyrinth seal mechanism, space communicates with ambient atmosphere.
When the spiral chute of star-wheel tooth and screw rod does not seal, be suction condition, along with bolt rod driving star-wheel rotates, screw slot and star-wheel tooth contact produce enclosed space.Now water enters the spiral chute of screw rod by water injection hole, and enclosed space is along with bolt rotary volume constantly dwindles, and water enters screw slot and star-wheel tooth fitting surface etc. and locates to form the effect that moisture film has played lubricated and sealing.The utility model utilizes water to carry out lubricated, pollution-free, the water of releasing between screw rod and star-wheel need not special processing, meets environmental requirement.Due to the effect of water, its compression is again desirable isothermal compression, and the more general dry type press of air quantity of per unit horsepower improves output 15%.The utility model adopts independently inner sealing technology, guarantees screw rod and the water lubrication system of star-wheel and absolutely not contacting of bearing, reduces the corrosion of lubricated water to bearing, guarantees that bearing reaches more than 30,000 hours working life.

Embodiment
A kind of single-screw air compressor that utilizes water lubrication, comprise casing, described casing is provided with suction port 7 and air outlet 8, in casing, be provided with one and there is spiral fluted screw rod 1, bilateral symmetry at screw rod 1 is arranged two star-wheels 2, the gear teeth of described star-wheel are meshed with the spiral chute of screw rod, it is characterized in that: on described casing, be provided with water injection hole 3, described water injection hole 3 arranges on the enclosure wall of spiral chute and star-wheel tooth engagement place, current spray in spiral chute from water injection hole, at casing, between screw slot and star-wheel tooth fitting surface, form moisture film to reach lubrication, screw rod 1 two ends penetrate the connection bearing 4 in the bearing chamber that is arranged on casing avris, screw rod two ends are provided with labyrinth seal mechanism 5, between bearing chamber and labyrinth seal mechanism 5, between space and ambient atmosphere, by spilled water hole 6, communicate.On the inter-agency casing of high pressure side screw rod and labyrinth seal, there is by-pass to communicate with low voltage side screw rod.Described star-wheel 2 is arranged on central shaft, the connection bearing 4 of the bearing chamber that is positioned at casing avris is worn at the two ends of central shaft, central shaft two ends are provided with labyrinth seal mechanism 5, between bearing chamber and labyrinth seal mechanism 5, between space and ambient atmosphere, also by spilled water hole 6, communicate.
When air compressor is opened, 1 rotation of motor drive screw, air enters in main frame by suction port 7.Screw rod 1 drives star-wheel 2 in casing, around axis separately, to move again and again together.When star-wheel tooth and screw spiral trough are not sealed, be suction condition, along with bolt rod driving star-wheel rotates, screw spiral trough and star-wheel tooth contact produce enclosed space.Now water enters closed spiro rod spiral chute by water injection hole 3, and enclosed space is along with bolt rotary volume constantly dwindles, and water enters screw slot and star-wheel tooth fitting surface etc. and locates to form the effect that moisture film has played lubricated and sealing.Air-water mixture through overcompression finally enters aqueous vapor bucket by relief opening, and in aqueous vapor bucket, complete the gentle separation of water, gas enters air supply system, water sedimentation is in aqueous vapor bucket, circulation replaces machine oil to main frame water supply used water, realizes four large effects of lubricated, cooling, sealing, noise reduction, and the oil-free air of high-quality 100% is provided, pollution-free, the water of releasing need not special processing, meets environmental requirement.Due to the effect of water, its compression is again desirable isothermal compression, and the more general dry type press (twin-screw) of air quantity of per unit horsepower improves output 15%.
Screw rod 1 is at a cavity with star-wheel 2, screw rod 1 transmission needs bearings, corrosion for fear of water to bearing, brand-new design sealing configuration, the two ends of screw rod 1 are divided into obstructed cavity by labyrinth seal mechanism 5, labyrinth seal mechanism 5 utilizes restrictor ring sealing, without friction, can move reliably and with long-term.Between bearing chamber and labyrinth seal mechanism 5, space communicates with atmosphere by spilled water hole 6, utilizes gravity principle, even if water infiltrate labyrinth seal mechanism also can flow out outside body.Make bearing chamber become a safe and reliable system, star-wheel bearings at both ends labyrinth seal mechanism also adopts same design.The utility model adopts independently inner sealing technology, guarantees screw rod and the water lubrication system of star-wheel and absolutely not contacting of bearing, reduces the corrosion of lubricated water to bearing, guarantees that bearing reaches more than 30,000 hours working life.
