Description
Technical field
The present invention relates to Compressor Technology field, especially relate to a kind of frequency-changeable compressor.
Background technique
At present, the pump of frequency-changeable compressor oil structure duplicates mostly in invariable frequency compressor, adopts traditional Oil sucking device in conjunction with bent axle tank structure.Its working principle is: when bent axle rotates, refrigeration oil enters oil duct by Oil sucking device, then utilizes centrifugal action to be pumped into movement top, realizes cooling and lubrication.Wherein, pump innage degree is subject to the restriction at speed of crankshaft and oil duct angle of inclination very large, when speed of crankshaft is too low, oil duct angle of inclination is when less than normal, refrigeration oil is subject to the eccentric force component that makes progress to be not enough to support freezing oil pump to be raised to expection height, thereby freezing oil film cannot normally be set up, make compressor movement can not get sufficient lubrication then the mechanical part such as bent axle piston wear and tear.Meanwhile, because refrigeration oil can not reach setting height, compressor movement cannot obtain fully cooling, and movement temperature is raise, the relevant moving element wearing and tearing of aggravation.When serious, also can cause the desulfurization of part component, decarburization or melt distortion, finally causing the abnormal increase of compressor power input loss or complete machine to lose efficacy.
Summary of the invention
The object of this invention is to provide a kind of frequency-changeable compressor, it have refrigeration oil can be steadily fully pump rise to predetermined altitude, thereby effectively widened compressor operating range, improved the performance of compressor and the feature of reliability.
The technical solution adopted in the present invention is: frequency-changeable compressor, comprise housing, in this housing, by spring bracket, be provided with the compressor body being suspended in this housing, this body interior is provided with rotor, this rotor has vertical through hole, this body bottom has base plate, and this housing inner chamber is under-filled refrigeration oil, described frequency-changeable compressor also includes fuel sucking pipe, this fuel sucking pipe comprises the metal ferrules in this through hole that is fixed on of interference fit, the inner interference fit of this metal ferrules be inserted with plastic tube, the upper end open of this plastic tube is communicated to this through hole, the lower end of this plastic tube extends in this refrigeration oil, simultaneously, in this plastic tube, be inserted with the pump housing, this pump body has cavity, this cavity upper end open, lower end closed, and the outer surface of this pump housing is provided with spiral burr, the lower end of this pump housing is provided with connection nose, and, in this connection nose, pass and have strut, this strut is to form after Spring Steel Wire bending, and the two ends of this strut are connected on this base plate.
The outer surface of described plastic tube is provided with at least 1 spacing taper platform, and this taper platform is compatible with the lower end surface of this metal ferrules, meanwhile, is uniformly distributed with at least 1 and is vertical groove on this metal ferrules inwall.
The advantage that the present invention has is: refrigeration oil steadily sufficient pump rises to predetermined altitude.The spiral burr that the filler opening place of frequency-changeable compressor of the present invention is provided with makes the angle of inclination of oil duct obtain very big reduction, the velocity component that slope effect while utilizing fuel sucking pipe with the pressure reduction between the pump housing and the rotation of spiral burr produces, make refrigeration oil can there is less resistance and larger upwards component, be convenient to refrigeration oil and rise smoothly more rapidly.Like this, freezing oil film can be able to rapid foundation, and refrigeration oil can be promoted to expection height, thereby has effectively widened the operating range of compressor, the performance that has improved compressor and reliability.

Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 7: frequency-changeable compressor, comprises housing 10.In this housing 10, by spring bracket 20, be provided with the compressor body 30 being suspended in this housing 10.These body 30 inside are provided with rotor 32, and this rotor 32 has vertical through hole 321, and these body 30 bottoms have base plate 31(or drain pan), this housing 10 inner chambers under-filled has refrigeration oil 40.Further say, this frequency-changeable compressor also includes fuel sucking pipe 50.This fuel sucking pipe 50 comprises the metal ferrules 51 in this through hole 321 that is fixed on of interference fit, these metal ferrules 51 inner interference fit be inserted with plastic tube 52.The lower end that the upper end open of this plastic tube 52 is communicated to this through hole 321, this plastic tube 52 extends in this refrigeration oil 40.Certainly, this base plate 31 is provided with the perforation of passing through for this plastic tube 52.That is, this plastic tube 52 by this metal ferrules 51 along with this rotor 32 is rotated.Meanwhile, in this plastic tube 52, be inserted with the pump housing 61.These pump housing 61 inside have the cavity 611 for counterweight, these cavity 611 upper end open, lower end closed.And the outer surface of this pump housing 61 is provided with spiral burr 612, the lower end of this pump housing 61 is provided with and connects nose 613.And, through there being strut 70, this strut 70 forms for Spring Steel Wire bending is rear in this connection nose 613.Certainly, this strut 70 can carry out suitable heat treatment to it in the preparation.The two ends of this strut 70 are connected on this base plate 31.Such as, the two ends of this strut 70 hook on two hooks set on this base plate 31.That is, the elasticity that this strut 70 has, makes this pump housing 61 be positioned at this plastic tube 52.Like this, this spiral burr 612 makes the angle of inclination of oil duct obtain very big reduction, after these plastic tube 52 rotations, be convenient to refrigeration oil 40 and there is the smooth rising compared with slight drag, make freezing oil film be able to rapid foundation, and refrigeration oil 40 can be promoted to expection height, has effectively widened the operating range of compressor, the performance that has improved compressor and reliability.
