Description
Technical field
The invention relates to compressor, particularly a kind of baffle arrangement of compressor.
Background technique
General compressor is the machinery of compressed fluid.Such compressor is by the seal container with certain inner space, and electronic and press part are formed.Electronic portion is installed in the seal container, can produce driving force, is subjected to the influence of electronic driving force, and press part compresses gas.Along with the difference of press part can be divided into many types.
The applicant once applied for the compressor different with the compressor compresses mode of prior art.Fig. 1, Fig. 2, Fig. 3 are the figure of the applicant compressor compresses portion aspect of once applying for.As shown in the figure, compressor compresses portion has following structure: inside is formed with inner space V, suction passage f1 and discharge stream f2, and suction passage f1 and discharge stream f2 are connected with inner space V; Running shaft 20 can connect the center of the inner space V that is inserted in cylinder assembly body D, and cylinder assembly body D secure bond is in the inside of seal container 10; Running shaft 20 combines with electronic the M that produces driving force.A certain amount of machine oil is equipped with in the bottom surface of seal container 10.
Cylinder assembly body D has following structure: inside has the cylinder 30 of cylindric through hole; Be combined with upper bearing 40 and lower bearing 50 respectively in the top and bottom of cylinder 30, upper bearing 40 and lower bearing 50 are formed inner space V with cylinder 30, are supporting running shaft 20 simultaneously.
Upper bearing 40 and lower bearing 50 are made up of following structure: shaft bearing plate 4151 has certain thickness and area; Prolong the supporting portion 42,52 that forms in the one side of shaft bearing plate 41,51 and have certain altitude and external diameter; Axle (20) patchhole 43,53 connects and is formed on supporting portion 42,52, in the centre of shaft bearing plate 41,51; Baffle plate groove 44,54 connects a side that is formed on shaft bearing plate 41,51.In upper bearing 40, its shaft bearing plate 41 covers a side of cylinder 30, inserts running shaft 20 in its shaft insertion hole 43.In lower bearing 50, its shaft bearing plate 51 covers the another side of cylinder 30, inserts running shaft 20 in its shaft insertion hole 53.
Running shaft 20 with certain external diameter and given length is made up of axial region 21, demarcation strip 22 and oil circuit 23.Axial region 21 is inserted in the shaft insertion hole 43,53 of upper bearing 40 and lower bearing 50; Demarcation strip 22 prolongs a side that is formed on axial region 21, and the inner space V of cylinder assembly body D is divided into the 1st SPACE V 1 and the 2nd SPACE V 2; Oil circuit 23 connects the inside that is formed on axial region 21.The demarcation strip 22 of running shaft is to have certain thickness circle, sees on from the side, and by the upside convex curved surface r1, the downside concave curved surface r2 of depression that protrude, the binding curved face part r3 that links convex curved surface r1 and concave curved surface r2 in addition constitutes.That is to say that demarcation strip 22 is waveform curved surfaces of sine wave shape, make convex curved surface r1 and concave curved surface r2 form 180 degree phase differences.
In addition, on the baffle plate groove 54 of the baffle plate groove 44 of upper bearing and lower bearing, be inserted with baffle plate 70 respectively, on upper bearing 40 and lower bearing 50, be combined with the elastic supporting member for supporting optical member 80 of elastic support baffle plate 70 respectively.At this moment level is observed cylinder assembly body D, and baffle plate 70 is in same phase place, and lay respectively at demarcation strip 22 about.
In baffle plate 70, form the demarcation strip contact surface portion 72 of chamfering having a side that certain thickness tetragonal baffle body 71 contacts with the waveform curved surface, be respectively arranged with outside curved face part 73 and inner curve portion 74 in the both sides of baffle body 71.Outside curved face part 73 contacts with the inwall of cylinder assembly body D inner space V, and 74 contacts of inner curve portion are at the outer circumferential face of running shaft 20.The baffle plate groove 44,54 that is inserted with baffle plate 70 is corresponding with the section configuration of baffle plate 70.
In addition, on cylinder assembly body D, be provided with and open and close valve 90, open and close valve 90 and open and close discharge stream f2, discharge compressed gas in compression volume V1b, the V2b of the 1st SPACE V 1 and the 2nd SPACE V 2.Be combined with the suction pipe 100 that is connected with suction passage f1 on the seal container 10, and be provided with baffler 110.
Operation process to compressor with said structure describes below.
At first, be subjected to the influence of electronic M driving force, running shaft 20 is rotated.Along with the rotation of running shaft 20, the demarcation strip 22 of running shaft 20 is rotated at the inner space V of cylinder assembly body D.Along with the demarcation strip 22 of running shaft 20 is rotated at the inner space V of cylinder assembly body D, contact is at and then interlock together of the baffle plate 70 of demarcation strip 22.The 1st SPACE V 1 of the inner space that is separated by demarcation strip 22 and the 2nd SPACE V 2 convert to respectively and suck SPACE V 1a, V2a and compression volume V1b, V2b, and, suck, compress and discharge gas repeatedly to the 1st SPACE V 1 and the 2nd SPACE V 2 in conjunction with opening and closing valve 90.
In addition, as shown in Figure 4, along with the demarcation strip 22 of running shaft is rotated in the inner space V of cylinder assembly body D, make the baffle plate 70 vertical with demarcation strip 22, under the state of elastic supporting member for supporting optical member 80 elastic support, by baffle plate groove 44,54 guiding, carry out straight line back and forth movement up and down along the waveform curved surface of demarcation strip 22.
