Description
Technical field
The utility model relates to the air compressor technical field, particularly a kind of oil-free sliding vane type air compressor.
Background technique
Known sliding-vane air compressor mainly is comprised of stator and rotor, and wherein stator is a cylinder, and rotor is eccentric the placement in cylinder, is disposed radially a plurality of chutes on rotor, the slide plate that in chute, setting can radially be free to slide.When rotor, slide plate under the effect of centrifugal force, throw away and with the cylinder inner wall close contact, make between adjacent two slide plates and cylinder inner wall to form the different closed compression chamber of a series of volumes, air is entered by suction port, along with the compression chamber volume reduces and compressed and discharged by relief opening.Because the matching gap design of slide plate top and cylinder inner wall in existing slide-blade air compressor is unreasonable, during work, be easy to cause hyperbaric chamber to arrive the Leakage Gas of low-pressure cavity, and the slide plate of oil-free sliding vane type air compressor adopts the self lubricating materials such as graphite, during work, the slide plate top is in the stator inner wall sliding friction, produce again amount of heat in the time of the slide plate wearing and tearing and make the slide plate distortion, more easily cause Leakage Gas, thereby cause exhaust loss large, pressure is not high, empty power consumption source.
The model utility content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and the oil-free sliding vane type that a kind of airtight effect is good, exhaust loss is few air compressor is provided.
The technical solution of the utility model is: a kind of oil-free sliding vane type air compressor, comprise the cylinder that is provided with suction port and relief opening, be eccentrically set on the rotor in the cylinder cavity, rotor shaft connects the output shaft of motor by coupling, it is characterized in that: described cylinder cavity has a seal groove, and it coordinates the sealing of formation face with the cambered surface of rotor; Described rotor radially has a chute, movable plant slide plate in chute, and the crescent-shaped space that slide plate surrounds rotor and cylinder cavity is separated into air aspiration cavity, compression chamber and exhaust cavity; Described slide plate consists of slide plate body and the movable slide plate piece that is embedded in slide plate body two end part, and the outer end profile in slide plate piece cross section is circular arc.
The inside of slide plate body described in the utility model is hollow-core construction, is divided into four cavitys, and the two end part of slide plate body offer strip groove, and each is communicated with each strip groove with two cavitys; The slide plate piece has strip projected parts and two pins that are complementary with described strip groove shape, and strip projected parts and pin be movable being embedded in strip groove and cavity respectively.
Cylinder one side described in the utility model has a cylinder cap, between cylinder and cylinder cap, by the O RunddichtringO, seals.
Between motor described in the utility model and cylinder, by connecting base, fix.
The beneficial effects of the utility model are: between rotor and cylinder inner wall, by face, seal and can effectively avoid the Leakage Gas of exhaust cavity to air aspiration cavity, simultaneously, slide plate throws away the wearing and tearing of slide plate piece auto-compensation with rotor the time, caused Leakage Gas reduces wear, thereby whole minimizing exhaust loss, realize good airtight effect, and the utility model is simple in structure, vibrate littlely, noise is low.
The accompanying drawing explanation
The sectional structure schematic diagram that Fig. 1 is the utility model embodiment;
Fig. 2 is the structural representation in the utility model embodiment cylinder.
Embodiment
Now reaching by reference to the accompanying drawings embodiment is further described the utility model:
As depicted in figs. 1 and 2, oil-free sliding vane type air compressor of the present utility model comprises cylinder 2, rotor 3, motor 6.Cylinder 2 one sides have a cylinder cap 1, between cylinder 2 and cylinder cap 1, by the sealing of O RunddichtringO, also are provided with suction port 21 and relief opening 22 on cylinder 2, with cylinder 2 cavitys, are communicated with respectively.Fixing by connecting base 5 between motor 6 and cylinder 2, rotor 3 is eccentrically set in cylinder 2 cavitys, and its rotor shaft 31 connects the output shaft of motor 6 by coupling 4.Rotor 3 radially has a chute 32, the interior movable plant slide plate of chute 32, and the crescent-shaped space that slide plate surrounds rotor 3 and cylinder 2 cavitys is separated into air aspiration cavity, compression chamber and exhaust cavity, and air aspiration cavity is communicated with suction port 21, and exhaust cavity is communicated with relief opening 22.Cylinder 2 cavitys have a seal groove 23, its cambered surface with rotor 3 coordinates the sealing of formation face, specifically, it is the position contacted with cylinder 2 inwalls at rotor 3, the curvature of cylinder 2 inwall molded line equates with the curvature of rotor 3 cambered surfaces, thereby, in the sealing of contact position formation face, effectively avoid the Leakage Gas of exhaust cavity to air aspiration cavity.
This slide plate consists of slide plate body 7 and the movable slide plate piece 8 that is embedded in slide plate body 7 two end part.Wherein, the inside of slide plate body 7 is hollow-core construction, is divided into four cavitys, and the two end part of slide plate body 7 offer strip groove, and each is communicated with each strip groove with two cavitys; Slide plate piece 8 has strip projected parts and two pins that are complementary with described strip groove shape, strip projected parts and pin be movable being embedded in strip groove and cavity respectively, the outer end profile in slide plate piece 7 cross sections is circular arc, and this profile can coordinate with cylinder 2 inwall molded line the reliable face sealing of formation.
The working principle of oil-free sliding vane type air compressor of the present utility model is as follows:
Motor 6 is by coupling 4 rotor driven 3 rotations, rotor 3 drives slide plate, slide plate under the effect of centrifugal force and slide plate body 7 cavity internal air pressures, throw away slide plate piece 8 and with the closely cooperate formation face sealing of cylinder 2 inwalls, thereby the crescent-shaped space that rotor 3 and cylinder 2 cavitys are surrounded is separated into air aspiration cavity, compression chamber and exhaust cavity.Rotor 2 is in rotary course, and the volume of air aspiration cavity constantly increases, thereby constantly absorbs ambient atmos; The volume of compression chamber reduces gradually, and pressure constantly increases, and air is compressed; The volume of exhaust cavity further reduces, and pressure further raises, and when gas pressure intensity is greater than drain pressure, compressed gas is pushed outlet valve open, drains into cooler bin through relief opening 22 and carries out after cooling being transported in gas holder.In the continuous operation process of air compressor, constantly carry out air-breathing, compression, exhaust process, thereby reach the purpose of continuous pressurized gas until reach regulation air pressure in gas holder.
