In connection with fig. 5 and 6, we find that: the use method of the oil-free variable frequency centrifugal compressor adopts any one of the oil-free variable frequency centrifugal compressors, and comprises the following steps:
s1, when the compressor is assembled and transported, two protection mechanisms 200 on two sides are required to be correspondingly assembled, a guide plate 205 and a limit slide block 207 are respectively installed in a guide groove 101b and a slide groove 101c, the limit slide blocks 207 on two sides can be reversely moved at the moment, when a bearing 204 connected with one side of the guide plate 205 is completely separated from the guide groove 101b, a straight plate shell 201b is required to be turned upwards along the bearing 204 and a rotating shaft 203, so that an arc-shaped shell 201a slides in a second limit groove 103b through a limit pulley 206, and when the two arc-shaped shells 201a are combined and contacted, the assembly can be completed by starting a fan 301;
s2, after the compressor is assembled, the blower 301 is required to be started, and because the two triggers 201d are in a mutually contacted state at this time, the blower 301 can pump air in the arc-shaped shell 201a through the air pipe 302 and the hose 303 at this time, so that air in the arc-shaped shell 201a is quickly lost, and meanwhile, the sliding sleeve 208a, the sliding rod 208b and air in the extrusion block 208f are pumped, and because after the arc-shaped shells 201a on two sides are combined, most of the extrusion block 208f can be completely attached to the surface of the compressor body 105a, so that when the blower 301 operates, the extrusion block 208f can be adsorbed on the surface of the compressor body 105a by continuously pumping air;
s3, after the compressor is moved to a designated position, the compressor needs to be installed and put into use, only the arc-shaped shells 201a on two sides are needed to be manually separated, when the arc-shaped shells 201a on two sides are far away from each other, the trigger 201d is closed, then the straight plate shell 201b slides along the guide groove 101b and simultaneously adjusts the overturning angle of the arc-shaped shell 201a along the hinge, after the adjustment, the arc-shaped shell 201a can fix itself under the action of gravity, at the moment, the fan 301 does not extract gas in the gas pipe 302 any more, and then extracts external gas and conveys the gas into the two gas pipes 302 and the hose 303, and at the moment, the gas is discharged along the arc-shaped shell 201a, the sliding sleeve 208a and the sliding rod 208b, so that the air flow rate on the surface of the compressor is greatly improved;
s4, because the limiting plate 103a, the first limiting groove 104, the second limiting groove 103b and the limiting pulley 206 are arranged, the arc-shaped shell 201a at two sides is separated, the arc-shaped shell 201a is required to be overturned along the hinge while the straight-plate shell 201b is overturned along the rotating shaft 203 and the bearing 204, at the moment, the position of the arc-shaped shell 201a, which is contacted with the limiting pulley 206, moves towards two sides along an arc angle, at the moment, the limiting pulley 206 pulls the limiting plate 103a in the second limiting groove 103b to slide along the first limiting groove 104, and after the straight-plate shell 201b and the arc-shaped shell 201a are adjusted to the proper positions, the limiting plate 103a and the limiting pulley 206 also stop moving, so that the limiting plate 103a and the limiting pulley 206 can play a limiting effect on the arc-shaped shell 201a and the straight-plate shell 201b in the moving process, and after the position adjustment of the arc-shaped shell 201a and the straight-plate shell 201b is completed, the limiting plate 103a and the limiting pulley 206 can play an auxiliary fixing effect, and the situation that the arc-shaped shell 201a and the straight-plate shell 201b are offset in the using process is avoided.
According to the oilless variable frequency centrifugal compressor and the application method thereof, after the compressor is assembled, the fan is required to be started, and because the two triggers are in a mutually contacted state, the fan can pump air in the arc-shaped shell through the air pipe and the hose, so that air in the arc-shaped shell is quickly lost, and meanwhile, the sliding sleeve, the sliding rod and air in the extrusion block are pumped.
