Description
Technical field
The utility model belongs to the air pump technical field, relates to a kind of seal ring tensioning mechanism of vortex type air pump.
Background technique
The impeller of vortex type air pump is made up of tens of blades; Air during wheel rotation in the middle of the blade has received action of centrifugal force; To the border movement of impeller, air gets into the belt cavity of the pump housing there, and the starting point from blade circulates in the same way more again.The circulating air flow that the impeller rotation is produced leaves toroidal cavity for use with high energy.Because impeller needs to rotate, and has the gap between impeller and the housing, so toroidal cavity is not sealing; High pressure draught flows out from the gap easily like this; Cause the loss of wind-force, the wind-force leakage loss has determined the efficient of air pump in essence, makes the usefulness of whole air pump reduce.
For avoiding the phenomenon of wind-force leakage loss, people are provided with seal ring and are used for seal clearance between housing and impeller.The material of seal ring adopts plastics or metal, also need be fixed on the housing with spring arch clasp with the fastening screw fastening.Seal ring will adopt opening form, and in order to dwindle alignment error, the seal ring of opening form can be reduced the impeller clearance as far as possible by expansion.Shown in accompanying drawing 1, a part and the housing of seal ring lean, and another part requires to leave less gap with the support ring of impeller, guarantee that wheel rotation is smooth, will seal ring be installed as far as possible accurately like this, make that the installation precision of seal ring is higher.And after seal ring was set, because seal ring fixes, the inboard out-of-flatness of the circular runout of impeller or support ring all caused the friction between impeller and the seal ring easily, thereby caused ring wear and lost efficacy.
The model utility content
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed can adjust automatically on a kind of vortex type air pump the tensioning mechanism of seal ring.
The purpose of the utility model can realize through following technical proposal: a kind of seal ring tensioning mechanism of vortex type air pump; The vortex type air pump comprises housing and impeller; It is characterized in that; Have annular groove between impeller and the housing, be provided with seal ring in the annular groove, the seal ring tensioning mechanism of this vortex type air pump comprises the open washer that is against the seal ring inner side surface and acts on the open washer two ends makes open washer and seal ring have the elastic component of the trend of expanding outwardly.
Elastic component acts on the two ends of open washer, and open washer crush seal circle expands outwardly, and makes a seal ring part can be close to the surface of housing, and another part can keep as far as possible little gap with impeller.If impeller when rotation circular runout is serious or support ring out-of-flatness and crush seal circle, seal ring extruding open washer so makes the two ends extruding elastic component of open washer and dwindles, and weares and teares with regard to having avoided the conflict of seal ring and support ring like this.Improve the working life of seal ring, also reduced the required precision that seal ring is installed simultaneously.
In the seal ring tensioning mechanism of above-mentioned vortex type air pump; Described elastic component comprises trapezoid block and the spring with two inclined-planes; Two inclined-planes of trapezoid block lean with the two ends of open washer respectively; One end of spring links to each other with the end face of trapezoid block, and the other end is connected on the housing, and trapezoid block has the trend of squeezing the open washer two ends under the effect of spring.Because trapezoid block is from microcephaly to the major part; The spacing of both sides constantly increases; Effect lower trapezoid piece at the spring tightening force has the trend that moves to the inside, and the two ends of trapezoid block two inclined-planes extruding open washer expand outwardly and the crush seal circle open washer so; Make the gap of seal ring and impeller littler, sealing effect is better; When seal ring and impeller are in Frotteurism, impeller crush seal circle, tensioning mechanism is adjusted automatically, and open washer extruding trapezoid block moves laterally and makes springs.
In the seal ring tensioning mechanism of above-mentioned vortex type air pump, described elastic component comprises the helical spring that two ends lean with the two ends of open washer respectively, and open washer has the trend that expands outwardly under helical spring elastic force.Helical spring is in compressed state, bestows open washer two ends elastic force all the time, makes seal ring can be resisted against on the housing; When seal ring received the extruding of impeller, spring received the extruding at open washer two ends and shortens, and makes seal ring not produce high-intensity friction with impeller.
In the seal ring tensioning mechanism of above-mentioned vortex type air pump, have spring seat on the described housing, helical spring is arranged in the spring seat.
In the seal ring tensioning mechanism of above-mentioned vortex type air pump, described elastic component comprises the shell fragment with biside plate and base plate, and the biside plate of shell fragment is against the two ends of open washer respectively, has the trend that expands outwardly at shell fragment effect under shed packing ring.The biside plate of shell fragment itself has the trend of outside stretching, extension, and this trend acts on the two ends of open washer, and open washer and seal ring are expanded outwardly, and leans with surface of shell; When seal ring received the impeller extruding, open washer shrank extrusion elastic.
In the seal ring tensioning mechanism of above-mentioned vortex type air pump, all have on the biside plate of said shell fragment can with the end of the open washer bayonet socket of inlay card mutually.The two ends of bayonet socket and open washer are inlay card mutually, is not easy to break away from, and reliable in structure is stable.
In the seal ring tensioning mechanism of above-mentioned vortex type air pump, have the groove that can hold shell fragment on the described housing, have through hole on the base plate of shell fragment, shell fragment passes through screw on groove.Shell fragment on housing, has strengthened the stability of shell fragment through screw.
In the seal ring tensioning mechanism of above-mentioned vortex type air pump, described shell fragment is processed by stainless steel material.Stainless steel shell fragment elasticity is strong, and endurance, long service life.
Compared with prior art, the seal ring tensioning mechanism of this vortex type air pump has the following advantages:
1. elastic component can be withdrawn seal ring automatically, prevents to damage with the long-term friction of impeller, has improved the working life of seal ring.
2. elastic component can fit tightly on the surface of housing seal ring, has improved sealing effect.
3. reduced the installation precision of seal ring.
