Accompanying drawing explanation
Fig. 1 is the structural representation of water lubrication sliding-vane air compressor.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is further detailed, but is not limited to protection domain of the present utility model.
For the variety of problems existed when solving to use lubricating oil as the lubricant of air compressor in the past, present embodiment provides a kind of novel sliding-vane air compressor, it is by the improvement of structure, the purpose using WATER AS FLOW MEDIUM as compressor lubricant can be realized, bring huge reform to sliding-vane air compressor.
nullSee Fig. 1，This water lubrication sliding-vane air compressor includes，Housing 9，Seam it is provided with respectively at the two ends of housing 9，Big end cap 3 it is installed with in one end seam of housing 9，In the endoporus of big end cap 3 central authorities, water lubriucated bearing 5 is installed，Small end cover 8 it is installed with in the other end seam of housing 9，Water lubriucated bearing 5 is also installed in the endoporus of small end cover 8 central authorities，Internally installed at housing 9 has stator 4，It is between big end cap 3 and small end cover 8，And two ends are fixing with big end cap 3 and small end cover 8 respectively is connected，The eccentric orfice running through two ends it is internally provided with at stator 4，Rotor 6 is installed in eccentric orfice，One end of rotor 6 is inserted in the water lubriucated bearing 5 on big end cap 3，The other end of rotor 6 is inserted in the water lubriucated bearing 5 on small end cover 8，And it is arranged at intervals with longitudinal fluting in the periphery of rotor 6，Slide plate 7 is installed in longitudinal fluting，Wherein，Slide plate 7 and big end cap 3、Small end cover 8、Stator 4 and rotor 6 constitute suction muffler and compression chamber.Also being separately installed with air filter 1 and inlet valve 2 on big end cap 3, wherein, inlet valve 2 connects with air filter 1 and described suction muffler respectively；Being installed with moisture separator 12 by corrugated tubing 11 above housing 9, and moisture separator 12 connects with compression chamber, is provided with check-valves 13 on moisture separator 12, this check-valves connects with moisture separator 12 and outside outlet pipe respectively.
Preferably, described water lubriucated bearing 5 is water-lubricated slide bearing；More preferably, this water-lubricated slide bearing is Water-based ceramics sliding bearing, wherein, this ceramic slide bearing material is carborundum or silicon nitride, the advantage such as hardness is high, water-fast, soda acid, good stability, life-span length that it has.
Above-mentioned water lubrication sliding-vane air compressor operation principle is: when rotor rotates under the drive of motor, by small end cover, big end cap, rotor, the volume closing chamber that slide plate and stator are constituted can occur ascending and descending alternate, wherein, air is after air filter filters, (corresponding suction muffler) is sucked through intake valve above-mentioned closing chamber volume becomes big when, (corresponding compression chamber) is compressed the when of diminishing, along with the lasting rotation of rotor, thus complete the process that air persistently sucks and compresses.Spraying into water during whole in compression chamber, compression chamber part is lubricated, seals, is cooled down, spray water in water lubriucated bearing is lubricated bearing and cools down simultaneously, and the compressed air of discharge is discharged by check-valves after moisture separator separates moisture.
Above-mentioned sliding-vane air compressor has the advantage that
1, this sliding-vane air compressor use water replace oil as lubricant, both served lubrication, seal, cool down, the effect of noise reduction, simultaneously as do not use any lubricating oil inside whole compressor host, so in whole work process compressor discharge be clean free of contamination compressed air, oil content is zero.Not having lubricating oil to avoid the need for considering the problem of lubricating oil low temperature " emulsifying ", such compressor is maintained at a temperature of relatively low running, and substantially can realize isotherm compression.Isotherm compression is the optimal duty of compressor, and efficiency is the highest, so the efficiency that the sliding-vane air compressor in the present embodiment can realize slide vane compressor maximizes.
2, the maintenance of user, upkeep cost are greatly lowered, and again need not change expensive lubricating oil and oil filtration applications, again need not worry about the compressed air oil content height of discharge and cause damage of product, scrap.
3, application water lubriucated bearing, it is not necessary to compression chamber and bearing chamber being separated without extra lubricating system, service life is long, it is ensured that compressor operation is reliable.
4, the whole work process of water lubrication sliding-vane air compressor, low-carbon environment-friendly, pollution-free, the effectively save energy.
As the improvement of technical scheme, see Fig. 1, water lubrication sliding-vane air compressor be also provided with water filter 10, with realize to lubrication water in impurity filter, the program particularly as follows:
It is provided with one in the bottom of housing 9 and cavity is installed, these installation cavity both sides are provided with an import and an outlet respectively, wherein, the pond installing the import of cavity side and provide lubrication water connects, opposite side import connects with external cooler, one side outlet connects with external cooler, and opposite side outlet connects with formation compression chamber between rotor 6 with stator 4, and water filter 10 is installed in this installation cavity body.
By the design of this structure, can carry out the lubrication water in compressor filtering, cool down after spray into again inside compressor, to prevent the mechanical breakdown caused owing to there is impurity in lubrication water, can realize lubricating the cooling of water simultaneously, reduce the running temperature of compressor, improve the safety and reliability of compressor operating.
Improvement as technical scheme, see Fig. 1 to be designed as by stator 4, ring flange it is fixedly installed respectively at the two ends, periphery of stator 4, it is provided with screw ring flange is circumferentially spaced, stator 3 is fixed and is connected with big end cap 3 and small end cover 8 by the screw on ring flange respectively, such as, use screw to be fixedly connected, to improve the firmness connected between each parts, improve its vibration resistance, it is achieved powerful making.
As the improvement of technical scheme, big end cap 3, small end cover 8, stator 4, rotor 6 and inlet valve 2 are all selected stainless steel part；Slide plate 7 selects rustless steel slide plate or nonmetal slide plate；Housing 9 aluminium alloy components, and have anticorrosive coat in the surface configuration of housing 9, it is ensured that compressor components uses both will not get rusty under water lubrication state and is not corroded, and increases the service life.
Specific embodiments of the present utility model is to carry out writing according to the mode gone forward one by one, and highlights the difference of each embodiment, and its similar portion can be with cross-reference.
