Description

Water-cooled oil-free lubricates slide vane compressor

Technical field

The utility model relates to a kind of air compressor, relates in particular to water-cooled oil-free lubrication slide vane compressor.

Background technique

Be applied in 0 at present ₃The air compressor of generating means and water treatment, the main employing has oil lubricating compressor and completely without two kinds of types of oily piston compressor.For oil lubricating compressor, no matter adopt the sort of structural type, it discharges the lubricant oil that all contains some in the gas, need take filtration to wait measure to be removed, and these filtrating equipment expense costlinesses, and DeGrain, and the oil lubrication piston compressor is arranged relatively completely without oily piston compressor, adopted piston ring to replace metal ring with self-lubricating property, and the roller bearing that envelope has grease is installed in connecting rod CONCENTRIC REDUCER hole, in the hope of reaching: the purpose of " completely without oil ", but use and show that the functional reliability of this structure is relatively poor, frictional heat between piston ring and the cylinder wall air-flow that can not effectively be cooled is taken away compressor exhaust temperature height, function consumption is big, influences the operating life of piston ring and the service behaviour of suction air valve.High operating temperature is also caused and is enclosed in that grease dissolves in the bearing, and under the rotating inertia force effect, constantly run off, finally cause catastrophe failure and operational failure, in addition, piston compressor has limited it in much application of occasions because the vibration and the noise of the decision of its structure characteristic are all bigger.

The model utility content

At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of water-cooled oil-free to lubricate slide vane compressor, and it can provide the pressurized air that does not have oil fully.

In order to achieve the above object, the utility model has adopted following technical proposals:

The utility model water-cooled oil-free lubricates slide vane compressor, and he can be driven by driving machine by connecting shaft head or belt transmission.This machine of compressor comprises cylinder, cylinder front and rear cover, rotor and slide plate.Described rotor eccentricity is arranged in the cylinder, rotor be provided with many oblique or toward to vane slot, in each vane slot slide plate is installed.Be provided with the smallest radial working clearance at the most approaching place between keeping away in rotor and the cylinder, be provided with the minimum axial direction working clearance between two ends of rotor face and the cylinder front and rear cover.

Described cylinder adopts the cooling of dual-layer wall water jacket, and the top and the bottom of cylinder front and rear cover inner chamber all have the duct to link to each other with the water jacket inner chamber, and cooling water imports from the aperture of cylinder bottom, flows out from aperture, cylinder front and rear cover top.

In the cylinder front and rear cover stuffing box bearing is housed, as the supporting of rotor, the cylinder front and rear cover also connects by flange rotor correctly is fixed on the correct position in the cylinder.In the described two ends of rotor rotating shaft back-up ring and seal ring are housed respectively.

The utility model makes it compared with prior art owing to adopted technique scheme, has the following advantages and characteristics:

1, guarantees that structurally rotor does not contact and keeps minimum working gap when rotated with between cylinder inner wall, the cylinder front and rear cover, has avoided the issuable when rotated friction of rotor body.

2, owing in cylinder and front and back cylinder end piece, be provided with cooling jacket and adopt water cooling mode, gas hydraulic fluid heat and the mechanical friction heat water that is cooled effectively absorbs and takes away during compressor operating, has guaranteed that the compressor long-term safety operates under the lower operating temperature.

3, slide plate adopts the material with high strength, selflubricating to make, and need not to inject lubricant oil in clutch release slave cylinder, can be implemented in running, and providing does not have oily, clean pressurized air fully.

4, owing to adopt water-cooled, operating temperature is low, helps improving andfrictional conditions between slide plate end and the cylinder inner wall, also prolongs the working life of grease in the stuffing box bearing greatly.

5, with respect to compressor in the form of piston, the utility model does not have reciprocating member, so running is steady, noise is low.

Embodiment

As shown in Figure 1 and Figure 2, the utility model water-cooled oil-free lubricates slide vane compressor, comprises cylinder, cylinder front and rear cover, rotor and slide plate.Adopt the flange location between described cylinder 1 and the cylinder front and rear cover 2 and be connected, rotor 3 is eccentrically set in the cylinder, rotor is provided with vane slot, slide plate 4 is installed in each vane slot, be provided with minimum toward to the working clearance at the most approaching place between rotor and the cylinder inner wall, be provided with the minimum axial direction working clearance between two ends of rotor face and the cylinder end piece.

Be respectively equipped with bearing 5, back-up ring 6 and bearing cap 7 between described two ends of rotor axle journal and the cylinder front and rear cover, its guide ring is arranged between rotor end-face and the bearing, by adjustment, can make to form between two ends of rotor face and the cylinder front and rear cover promptly not contact and can keep minimum working gap to the back-up ring axial length.Be provided with seal ring 8 between cylinder front and rear cover and back-up ring, be filled with high-temperature grease and oil sealing 10 is housed in the bearing cap 9 of rotor shaft overhanging end, seal ring and oil sealing are respectively applied for and stop in the lubricant grease inflow cylinder and outside the outflow machine.

Described cylinder one side is provided with suction port 12 and air-inlet cavity 13, communicate with cylinder inner cavity by hole slot 11, be provided with exhaust cavity 14 and relief opening 15 on the top of cylinder opposite side, also be respectively equipped with cooling jacket 16 in cylinder and the cylinder front and rear cover, communicate with water intake 17 and water outlet 18.

The working principle of the lubricated slide vane compressor of the utility model water-cooled oil-free can be in conjunction with Fig. 1, Fig. 2 is described as follows: external impetus can reach rotor by shaft coupling head or belt, the rotation of outrigger shaft band rotor, epitrochanterian slide plate skids off from slide plate under the action of the centrifugal, the inwall of cylinder is close in its end, and the crescent-shaped space between cylinder and the rotor is divided into several work cells, air sees through air stream and filters clean device and filter the back and be inhaled into the cell of working in the cylinder from import and export and air-inlet cavity and by hole slot, rotation along with rotor, the work cell volume is dwindled gradually, the air that is closed within it is compressed and the pressure rising, when work cell and the exhaust cavity on the cylinder connection of sealing out-of-date, pressurized air is just discharged from exhaust port, and use is provided.Because the slide plate in the utility model adopts self lubricating material to make, so to all not needing other lubricant method on the rubbing surface of rotor, the frictional heat of its production and air compression heat are absorbed by the cooling water in flow through cylinder and the cylinder head jacket and take away to the rubbing surface of cylinder inner wall and its side in its end.
