Abstract
The utility model relates to the technical field of general compressing machinery, and in particular relates to a single-screw water-lubricating air compressor. Most oil-lubricating air compressors in the prior art have the problems such as high heating values and increased maintenance costs due to the maintenance of filtering elements, the change of oil products and the like. The single-screw water-lubricating air compressor comprises a case body, a spindle, a screw rod and star wheel mechanisms, wherein the spindle provided with the screw rod is assembled in the case body longitudinally; the two star wheel mechanisms are assembled on the two sides of the screw rod to form an engagement pair; the star wheel mechanisms comprise plane star wheels, star wheel shafts, star wheel bearing seats, end face bearings, inner sleeves of star wheel bearings and outer sleeves of the star wheel bearings; the plane star wheels are fixed on the star wheel shafts; and the star wheel shafts are assembled in seat holes of the case body by the end face bearings, the outer sleeves of the star wheel bearings, the inner sleeves of the star wheel bearings and the star wheel bearing seats. The single-screw water-lubricating air compressor has the advantages that water is used for replacing oil so that the effects of cooling and noise reduction are achieved while the lubrication is carried out; the vibration is small; pollution-free clean gas is used as compressed air; the running is stable; and the operating cost is low.
Description
Technical field
The utility model relates to universal compressed field of mechanical technique, a kind of specifically single screw rod water lubrication air compressor.
Background technique
Compressor is a kind of common universal machine, and along with technological progress and people pay attention to further to the energy and environmental protection, the compressor of energy-saving and environmental protection, high reliability has become the inexorable trend of compressor development.The single screw compressor vibration is little, noise is low, reliability is high, obtained using widely, but in the prior art oil lubrication air compressor exist mostly filter element maintenance, change that maintenance cost that oil product etc. brings increases and problem such as heating value is bigger, increased user's operation expense (being the expense and the energy consumption cost of daily maintenance, standby redundancy).Because it is very big that operating cost accounts for the ratio of compressor gross investment, therefore, the user particularly payes attention to the expense of operation and maintenance when selecting compressor.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of single-screw air compressor of water lubrication is provided, and can reduce user's operation expense.
The technical solution of the utility model is: comprise casing, main shaft, screw rod, also comprise star-wheel mechanism; Main shaft one end is connected with casing by angular contact ball bearing, and is set with mechanical seal; The other end is connected with casing by cover and SiC bearing overcoat in the SiC bearing; Screw rod is installed on the main shaft by interference fit, and two cover star-wheel mechanism reverse vertical are assemblied in the screw rod both sides and form engagement pair; Star-wheel mechanism comprises plane star-wheel, spider gear shaft, spider gear shaft bearing, end face bearing, star-wheel bearing outside, star-wheel bearing inner sleeve; On spider gear shaft, spider gear shaft is assemblied in the seat hole of casing by end face bearing, star-wheel bearing outside, star-wheel bearing inner sleeve and spider gear shaft bearing the plane star-wheel by dowel fixes.
Further, described screw rod is provided with six screw channels.
Further, described plane star-wheel is provided with 11 teeth.
The utility model has the advantages that: adopt water to replace oil, realized the effect of cooling, noise reduction in the time of lubricated, dynamic lubrication excellent performance, high working efficiency, working stability is reliable, vibrate less, running steadily, noise is extremely low, whole compression process does not have the participation of oil fully, therefore the pressurized air that is provided is free of contamination clean gas, and the water of releasing need not to carry out special processing, compliance with environmental protection requirements.The easily damaged parts of single-screw air compressor is few, and main bearing can be worked 50,000 hours even long lifetime more, and operating cost is lower.
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is elaborated.
Description of drawings
Fig. 1 is the utility model main machine structure schematic representation;
Fig. 2 is of the present utility model along main shaft longitudinal profile structural representation;
Fig. 3 is a cross-sectional structure schematic representation of the present utility model.
Among the figure: 1, casing, 2, main shaft, 3, screw rod, 4, plane star-wheel, 5, spider gear shaft, 6, the end face bearing, 7, star-wheel bearing inner sleeve, 8, star-wheel bearing outside, 9, the spider gear shaft bearing, 10, the triangle exhaust port, 11, angular contact ball bearing, 12, mechanical seal, 13, the SiC bearing overcoat, 14, cover in the SiC bearing.
Embodiment
Embodiment 1
From Fig. 1---3 as can be known, and the utility model comprises casing 1, main shaft 2, screw rod 3, also comprises star-wheel mechanism; Main shaft 2 vertically is assemblied in the casing 1, and main shaft 2 one ends are connected with casing 1 by angular contact ball bearing 11, and isolates with the aqueous medium of main frame box house by the mechanical seal 12 that is sleeved on the main shaft 2; The other end is connected with casing 1 by cover 14 and SiC bearing overcoat 13 in the SiC bearing; Screw rod 3 is installed on the main shaft 2 by interference fit, and screw rod 3 is provided with six screw channels, and two cover star-wheel mechanism reverse vertical are assemblied in screw rod 3 both sides and form engagement pair; Described star-wheel mechanism comprises plane star-wheel 4, spider gear shaft 5, spider gear shaft bearing 9, end face bearing 6, star-wheel bearing outside 8, star-wheel bearing inner sleeve 7; The plane star-wheel is provided with 11 teeth, and on spider gear shaft 5, spider gear shaft 5 is assemblied in the seat hole of casing 1 by end face bearing 6, star-wheel bearing outside 8, star-wheel bearing inner sleeve 7 and spider gear shaft bearing 9 plane star-wheel 4 by dowel fixes.
Working principle of the present utility model is: the composition engagement pair of the plane star-wheel mechanism of a cylindrical screw 3 and two balanced configurations, plane star-wheel 4 is divided into two spaces up and down with the screw rod 3 of its engagement with the box house space, be that the bottom surface of each screw channel of screw rod 3 and groove side, the parallel spider piece flank of tooth of screw channel, casing 1 internal surface form a compression chamber, each compression chamber all realizes the working procedure of compressor.When main shaft 2 rotations, drive two parallel star-wheel 4 teeth respectively and in screw rod 3 screw channels, rotate, the gas in the screw channel gradually reduces, and when reaching design pressure, is arranged to the casing outer passage by the triangle exhaust port 10 on casing 1 surface.
Because cylindrical screw and two star-wheel balanced configurations, have desirable equilibrium of forces, so its axial force and radial force can both cancel out each other, guaranteed that air compressor moves reliably and with long-term.Parallel star-wheel 4 uses advanced wear-resistant material PEEK, and all the other materials all adopt stainless steel to prevent to get rusty, and end face bearing 6, star-wheel bearing outside 8, star-wheel bearing inner sleeve 7 all adopt silicon carbide material.
Should be noted that at last: above embodiment is used to illustrate that the technical solution of the utility model is not intended to limit; the those skilled in the art makes amendment to mode of execution or the part technical characteristics is equal to replacement; and do not break away from the essence of technical solutions of the utility model, all should be encompassed within the utility model scope required for protection.
