Abstract
The utility model designs a single-screw air compressor utilizing water lubrication. The single-screw air compressor comprises an enclosure, a single screw, a double star wheel, a bearing, an air inlet and an air outlet and is characterized in that the two ends of the single screw penetrate through a connecting bearing in a bearing chamber at the side of the enclosure, and a polytetrafluoroethylene water seal and a ceramic guide sleeve are sleeved on the single screw at one side, adjacent to the enclosure, of the bearing chamber; the polytetrafluoroethylene water seal is positioned on the outside of the ceramic guide sleeve, the star wheel is arranged on a shaft, and the two ends of the shaft penetrate through the connecting bearing in the bearing chamber at the side of the enclosure. The single-screw air compressor provided by the utility model has the advantages that water replaces engine oil so as to realize four effects of lubrication, cooling, seal and noise reduction; the single-screw air compressor provides high-quality 100% oil-free air and is pollution-free; discharged water does not need special treatment and meets environmentally-friendly requirements; and the compression is ideal isothermal compression due to the action of water, and the air quantity of per unit horsepower is improved by 15% compared with that of a general dry-type pressing machine (a double screw).
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 that uses now mainly is: piston type, single-screw air compressor and screw air compressor, and wherein so that single-screw air compressor is little to shake, noise is low, be easy to safeguard, advantage that the life-span is long has obtained promoting the use of widely.Its cardinal principle is to adopt one to have six cylindrical screw rods of spiral fluted, arranges two star-wheels in the bilateral symmetry of screw rod, has 11 teeth to be engaged in the spiral chute of screw rod on each star-wheel.When air compressor was opened, motor was through the rotation of elastic coupling flexible coupling drive screw, and air gets in the main frame through suction port.Screw rod drives star-wheel and in casing, moves again and again around axis separately together.When star-wheel tooth and screw slot do not seal is suction condition, and along with the bolt rod driving star-wheel rotates, screw slot and star-wheel toe joint touch the generation enclosed space.This moment, the star-wheel tooth was to being positioned at the air compression of screw slot; In order to lubricate; Can spray into lubricant oil this moment; Because because of the machine oil of participating in lubricating is to be to mix with pressurized air, pressurized air also will carry out follow-up Oil-gas Separation after producing in single-screw air compressor work, increase burden for follow-up processing.Therefore demand developing novel single-screw air compressor urgently to solve the problem that exists at present.
Summary of the invention
The purpose of the utility model be solve in the existing technology in the single-screw air compressor work because of the machine oil of participating in lubricating be to be to mix with pressurized air; Pressurized air also will carry out follow-up Oil-gas Separation after producing; Give the follow-up processing existing the problems referred to above that increase burden, a kind of single-screw air compressor that utilizes water lubrication is provided.A kind of single-screw air compressor that utilizes water lubrication of the utility model design; Comprise casing, single screw rod, double star wheel, bearing, suction port, air outlet; It is characterized in that: the two ends of single screw rod penetrate connection bearing in the bearing chamber of casing avris, on single screw rod of nearly casing one side of bearing chamber, are set with teflon water seal and ceramic guide pin bushing, and the teflon water seal is positioned at the ceramic guide pin bushing outside; Star-wheel is installed on one; The two ends of axle penetrate connection bearing in the bearing chamber of casing avris, on single screw rod of nearly casing one side of bearing chamber, are set with teflon water seal and ceramic guide pin bushing, and the teflon water seal is positioned at the ceramic guide pin bushing outside.The utility model has the advantages that the water water replaces machine oil; Realize four large effects of lubricated, cooling, sealing, noise reduction, the oil-free air of high-quality 100% is provided, pollution-free, the water of releasing need not special processing; Compliance with environmental protection requirements; Because the effect of water, its compression is again desirable isothermal compression, and the dry type press (twin-screw) that the air quantity of per unit horsepower is more general improves output 15%.
Description of drawings
Accompanying drawing 1 is the section of structure of the utility model, and Fig. 2 is the side structure generalized section of Fig. 1.
Embodiment
Working principle is following:
Supporting one in the casing of main frame and having six columniform single screw rods of spiral fluted, be furnished with two star-wheels, having 11 teeth to be engaged in the spiral chute of screw rod on each star-wheel in the bilateral symmetry of single screw rod.When air compressor was opened, motor was through the rotation of elastic coupling flexible coupling drive screw, and air gets in the main frame through suction port.Single screw rod drives star-wheel and in casing, moves again and again around axis separately together.When star-wheel tooth and screw slot do not seal is suction condition, and along with the bolt rod driving star-wheel rotates, screw slot and star-wheel toe joint touch the generation enclosed space.This moment, water got into the closed spiro rod groove through water filling hole, and enclosed space constantly dwindles along with screw rod rotates volume, and water gets into 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 gets into the aqueous vapor bucket through relief opening at last, and in the aqueous vapor bucket, accomplishes the gentle separation of water, and gas gets into air supply system; Water sedimentation is in the aqueous vapor bucket; Circulation replaces machine oil to the 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, compliance with environmental protection requirements.Because the effect of water, its compression is again desirable isothermal compression, and the dry type press (twin-screw) that the air quantity of per unit horsepower is more general improves output 15%.
Adopt independently inner sealing technology, guarantee screw rod and the water lubrication system of star-wheel and contacting anything but of bearing, reduce of the corrosion of lubricated water, guarantee that bearing reaches more than 30,000 hours working life bearing.
Single screw rod and star-wheel are at a cavity; Screw drive needs bearings; For fear of the corrosion of water to bearing, brand-new design teflon water seal and ceramic guide pin bushing structure, the two ends of single screw rod lean on ceramic guide pin bushing and teflon water seal to be divided into obstructed cavity; Make bearing lubrication become an independently system, separate with the cavity of single screw rod and star-wheel.Will cause two cavitys to be connected so if the pottery guide pin bushing has worn and torn, therefore we use pottery, silicon carbide material, three kinds of materials of plasma sprayed ceramic to supply customer selecting in the selection of guide pin bushing, all are abrasion resisting materials.The lubricated cavity of star-wheel bearings at both ends also adopts same design.
