Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the regulation structure of centrifugal compressor of the present utility model and centrifugal compressor are further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, Figure 2 with shown in Fig. 8, a kind of regulation structure of centrifugal compressor, for regulating the width of the diffusion outlet 8 of the impeller of centrifugal compressor, centrifugal compressor comprises casing 6, and diffusion outlet 8 is formed jointly by the bearing 5 be fixedly connected with casing 6 and mounting plate 7.The regulation structure of centrifugal compressor comprises drive unit 1, driving ring 2, transmission device 3 and adjustable device 4, and driving ring 2 is connected with drive unit 1 and transmission device 3 respectively, and adjustable device 4 is connected with transmission device 3, and blocks diffusion outlet 8.
Driving ring 2 is circular shape, and is sleeved on bearing 5; Drive unit 1 drives driving ring 2 to do the relative rotary motion coaxial with bearing 5.Driving ring 2 drives adjustable device 4 to move by transmission device 3, blocks scope for what change adjustable device 4, thus regulates the width of diffusion outlet 8.
Like this, drive unit 1, driving ring 2, transmission device 3 and adjustable device 4 all can independently be arranged, easy for installation, and adjustable device 4 is blocked to the control of the scope of diffusion outlet 8 not by the impact of centrifugal compressor itself, can control by drive unit 1, driving ring 2 and transmission device 3 are independent, thus it is more accurate to the adjustment of diffusion outlet 8, and can realize when centrifugal compressor quits work, whole the blocking of adjustable device 4 pairs of diffusion outlets 8, thus prevent the refluence of refrigerant gas from entering centrifugal compressor.
As a kind of embodiment, as shown in Figures 2 to 4, driving ring 2 is arranged slotted eye 9, slotted eye 9 is divided into three sections (being divided into three sections from left to right in Fig. 2), be followed successively by the first sector hole, the second sector hole and the 3rd sector hole, first sector hole and the 3rd sector hole are straight trough hole, and the second sector hole is tilted slotted hole; The line of centres of the line of centres of the first sector hole, the line of centres of the second sector hole, the 3rd sector hole is connected to form the line of centres of slotted eye 9 in turn, dotted line in Fig. 3 is the center line line of slotted eye 9, wherein, the line of centres of the first sector hole is parallel with the line of centres of the 3rd sector hole, acute angle between the line of centres of the second sector hole and the line of centres of the 3rd sector hole is 14.5 ° ~ 40 °, preferably 15 ° ~ 25 °; Wherein, the acute angle between the line of centres of the second sector hole and the line of centres of the 3rd sector hole is equal with the angle of the angle α in Fig. 4.
α angle is too little, and the angle that driving ring 2 rotates is just large, and be unfavorable for structural design, working efficiency is also lower; α angle is too large, is found out by force analysis figure, and the component F1 promoting slide bar 11 just reduces, and the transverse force F2 suffered by slide bar 11 increases, then the resistance promoted is relatively comparatively large, and effort is just compared in controlling mechanism work, so should determine a suitable α angle value.Impeller outlet width is generally less than 15mm, then the range of operation of adjustable device 4 is less than 15mm, so the hypotenuse height h of the slotted eye 9 of driving ring 2 is no more than 15mm.L is the circumferentially deploying length that driving ring 2 rotates.For hypotenuse height h=15mm, L is value empirically, is calculated as follows:
If L=58, then tg α=15/58=0.258, α=14.5 °; If L=18, then tg α=15/18=0.83, α=39.8 °; Obtain conclusion: α angle span is 14.5 ° ~ 40 °.Wherein, 15 ° ~ 25 ° is optimum valuing range.
