Abstract
The present invention discloses a rotating sliding vane compressor, which comprises a front check plate, a rear check plate, a top cover, a rear cover, an air cylinder, a rotor crankshaft and sliding vanes, and the compressor is characterized in that the sliding vanes and the inner wall of the air cylinder are attracted to each other by magnetic force. Before the compressor is started, the magnetic force between the sliding vanes and the inner wall of the air cylinder automatically drags out the sliding vanes and tightly presses the sliding vanes on the inner wall of the air cylinder, thus greatly reducing noise such as the vibrating noise emitted by the starting compressor, the vibrating noise emitted by the sliding vanes running to an exhaust opening and ticks caused by the compressor lacking oil, and therefore the noise problem of the compressor is greatly overcome.
Description
Technical field
The present invention relates to the rotary slide sheet type compressor in air condition compressor field, particularly used for automobile air conditioning.
Background technique
The structure of existing used for automobile air conditioning rotary vane compressor is shown in Figure 1A, 1B, and slide plate 8 is wherein generally processed by high tensile aluminium alloy, and rotor bent axle 6 is processed by ferro-alloy; Rotor bent axle 6 rotates in cylinder 7, and slide plate 8 slides in the vane slot of rotor bent axle 6 through back pressure and action of centrifugal force that oil controlling valve provides.Because slide plate 8 back pressures are very little, it is big that centrifugal force becomes suddenly during startup, and the chatter sound appears in slide plate impingement cylinder 7 easily.During exhaust because the balance of slide plate 8 pressure at both sides changes suddenly, the chatter sound appears easily also.When causing the inner temporary transient oil starvation of compressor for a certain reason, back pressure reduces, and perhaps centrifugal force is not enough during idling, and slide plate 8 will bounce on cylinder and sound occur rattling away.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of rotary slide sheet type compressor, its noise problem is greatly improved.
The objective of the invention is to realize like this: a kind of rotary slide sheet type compressor, comprise front screen, backboard, top cover, bonnet, cylinder, rotor bent axle and slide plate, it is characterized in that: described slide plate is through magnetic force and the mutual adhesive of cylinder inner wall.
Described slide plate is to be processed by permanent-magnet materials, perhaps on slide plate, is provided with permanent-magnet materials portion; The rotor bent axle adopts diamagnetic material or Paramagnetic material to process; Cylinder inner wall is processed by ferromagnetic substance.
Described slide plate is processed by ferromagnetic substance, perhaps on slide plate, is provided with ferromagnetic substance portion; The rotor bent axle adopts diamagnetic material or Paramagnetic material to process; Cylinder inner wall studs with the permanent-magnet materials layer.
Said slide plate is at the rubbing surface that contacts with the rotor bent axle, and/or is provided with concave point at the rubbing surface that contacts with front screen, backboard.
Said rotor bent axle is at the rubbing surface that contacts with slide plate, and/or is provided with concave point at the rubbing surface that contacts with front screen, backboard.
Said permanent-magnet material is the Ni-based or cobalt base amorphous alloy of iron.
Said slide plate surface by the permanent-magnet materials manufacturing scribbles coating.
The present invention is before compressor start; Magnetic force between slide plate and the cylinder inner wall is just drawn slide plate automatically; Make slide plate press the inwall of cylinder all the time; Thereby significantly reduce chatter sound when for example starting compressor, the chatter sound when slide plate runs to relief opening, compressor owing to the noises such as the sound of rattling away that oil starvation causes, make the noise problem of compressor improved greatly.
