Abstract

The utility model relates to a rotary sliding-vane compressor which mainly consists of a rotor, a sliding piece, a cylinder body and the cylinder covers which are arranged on the two ends of the cylinder body. The rotor is supported by the bearings in the cylinder covers and are eccentrically arranged in the columnar cylinder body. The inside of a groove which has a wider axial direction and is arranged on the rotor is provided with a thicker sliding piece which is made of new colophony matrix composite, an isolating circle is arranged between the end surface of the rotor and the inner cover of the bearing, the two sides of the cylinder body are provided with gas inlet and gas outlet, the inside of the rabbet of the end surface of the cylinder cover is embed with a cylinder mat and is tightly airproofed with the cylinder body by bolts, and the outsides of one end of the cylinder covers are filled with gland boxes by bolts and the grooves of the gland boxes are provided with airproofing materials. The outsides of the gland boxes are provided with stuffing rings by bolts and the other end of the cylinder covers are provided with bearing glands and the cylinder covers as well as the bearing glands are tightly airproofed by bolts and airproofing elements. The utility model has the advantages of small cubage, low cost, big wind rate, small noise, long using life, easy manufacturing, installation, use and maintenance, etc.

Description

The revolution sliding-vane air compressor

The utility model is a kind of revolution sliding-vane air compressor.

The present big heaviness of using of piston type air compressor body, air quantity is little, and maintenance and repair is special inconvenient; Screw air compressor cost height requires sternly air quality, and general environment is difficult to satisfy service condition, and mostly is little air quantity

For overcoming the above-mentioned defective of prior art, the utility model aims to provide that a kind of volume is little, cost is low, air quantity is big, the revolution sliding-vane air compressor of long service life.

For achieving the above object, the utility model mainly is made of the cylinder cap at rotor, slide plate, cylinder body and two ends.Rotor places in the cylinder body by the bearings off-centre in the cylinder cap, and is tangent with inboard wall of cylinder block line cylindraceous, and the better and cylinder body of its sealing effect is easily processed.The slide plate of thicker novel resin-based composite material system is housed in the groove of axial broad on the rotor, has increased the working life of cylinder body and slide plate.Between rotor end-face and bearing inner sleeve cage ring is housed, can plays position-limiting action and prevent that pressurized gas from leaking bearing.The cylinder body both sides are respectively equipped with suction port and relief opening.Stud with the cylinder pad in the seam on the cylinder cap end face, again by bolt and cylinder body fit sealing.Cylinder cap at one end is outer to connect Stuffing box by bolt, and Stuffing box is equipped with sealing material by in the annular recess of rotor axial region, can stop pressurized gas and lubricant grease to leak.Stuffing box also can compress bearing outside in addition, and the axial motion of rotor is played position-limiting action.Gland also is housed outside Stuffing box makes both fastening by bolt.Bearing gland is housed outside the cylinder cap of the other end and makes both fit sealings, can compress bearing outside and the rotor axial string has been moved position-limiting action, and prevent that pressurized gas and lubricant grease from leaking by bolt and Sealing.

When rotor leaned on powered rotation, slide plate was thrown away from rotor recesses by centrifugal action, and its end face is close to inboard wall of cylinder block and is slided, and formed the plurality of sector space with table in the cylinder body.Rotor rotation, because of its off-centre places in the cylinder body, the volume pests occurrence rule of each sector space changes, and finishes air-breathing, compression, exhaust process.Along with rotor does not stop rotation, air constantly sucks from suction port, and pressurized air is constantly discharged from relief opening.

Owing to take above-mentioned technical solution, the utlity model has that volume is little, cost is low, air quantity is big, noise is little, long service life, be easy to advantages such as processing, installation, maintenance and use.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the sectional view of Fig. 1.

Below in conjunction with accompanying drawing, further set forth specific embodiment of the utility model.Referring to accompanying drawing as can be known, the utility model mainly is made of the cylinder cap 3 at rotor 5, slide plate 9, cylinder body 6 and two ends.Rotor 5 by 42 in the cylinder cap 3 * * * serial bearing 4 supports off-centre and places in the cylinder body 6 cylindraceous.The slide plate 9 of thicker novel resin-based composite material system is housed in the groove of axial broad on the rotor 5, and inner rooms are equipped with cage ring 7 in rotor 5 end faces and the bearing 4.Cylinder body 6 both sides are respectively equipped with suction port a and relief opening b.Stud with cylinder pad 10 in the seam of cylinder cap 3 end faces, again by bolt and cylinder body 6 fit sealings.By bolt Stuffing box 2 is housed outside the cylinder cap 3 at one end, Stuffing box 2 is equipped with sealing material 11 by in the annular recess of rotor 5 axial regions.Gland 1 also is housed outside Stuffing box 2 and makes both fastening by bolt.Bearing gland 8 is housed outside the cylinder cap 3 of the other end and makes both fit sealings by bolt and Sealing.
