Description of the invention (1) Field of the invention: The present invention generally refers to a centrifugal compressor 'and in particular a transmission positioning mechanism of a centrifugal compressor variable pipeline lifter' and the back Gap adjustment mechanism. BACKGROUND OF THE INVENTION When using centrifugal vapor compressors in a wide range of compression loads, one of the most important issues is the degree of stability of the fluid as it passes through the compressor. Compressor inlet 'impeller and booster passages must be designed to provide the desired maximum accumulation rate. When a low volume flow rate passes through the compressor, the fluid becomes unstable. Once the volume flow rate drops from a stable range, some slightly unstable fluid will enter the compressor. Within this range, there will be some backflow 'in the booster channel, which will generate noise and reduce compressor efficiency. Under this range, the compressor enters the so-called assault wave, which generates a periodic complete backflow in the booster channel, destroying the efficiency of the machine and endangering the integrity of the machine components. Since for many compressor applications, a wide range of volume flow rates is desired, many modifications have naturally been suggested to improve the stability of the fluid at low volume flow rates. Many technologies have been designed to maintain high machine efficiency over a wide operating range. In U.S. Patent No. 4,378,194, the entire booster wheel gallery can be varied based on changes in load to match machine performance to changing load requirements. Adjustable boost restrictor is also described in U.S. Patent No. 3 362 625. The fluid in the booster can be adjusted to improve fluid stability at low volume flow rates. In centrifugal compressors, A common technique for maintaining high operating efficiency of the lifanyuan 'is a variable width boost through a fixed booster guide vane. -4- This paper size is applicable to China's national standard (CNS &gt; A4 size (210X297mm) nn In nn m · IJ-, C ^ f ^ K ^^^ 1 la (Please read the precautions on the back before filling out this page) Printed by the Consumers' Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs. V. Description of the Invention (2) "Usage", US Patent Nos. 2 996 996 and 4 378 194, belonging to the same client, describe variable width blade boosters in which the booster blades are fixedly attached to one of the booster walls, such as using bolts. Blades Suitable to pass through an opening in the other wall, thus allowing the geometry of the booster to change with load conditions. The fixed installation of the booster blades to one of the booster walls reveals many problems, especially regarding the machine Manufacturing, maintenance and operation. In the process, there is only a small amount of space to fix the blades. When the blades return to their original position, any misalignment of the blades will cause the blades to tangle or rub against the wall. Similarly, if one or more blades in series in the assembly must be Replacement, generally the entire machine must be disassembled to facilitate replacement. The efficiency of the compressor can be greatly enhanced by changing the outlet geometry of the booster. US patent application serial number 08/6588, which is generally assigned. 〇ι, a variable geometry pipeline booster has been disclosed, and hereby incorporated into a reference case. The variable geometry pipeline booster (also known as a split loop pipeline booster) Divided into-the first inner ring and a second outer ring. There is a complementary inflow channel area between the inner ring and the outer ring. This means that the inflow channel area of each inner ring will correspond to a complementary inflow channel area in the outer ring. κ The inner ring and the outer ring can rotate with each other individually to improve the efficiency by changing the pressure range between the fully open position and the partially closed Π knife closed position. In the partially closed position, the misalignment of the exit tube of the lifting device will increase the bath sound. Rotation of the ring and The best material point, the material becomes extra ^ sound 'and reduces the efficiency. The geometric tolerance in the centrifugal compressor is quite small. With the same choice ^, at the same time,' negative in the compressor ------------------- ITJ -------- (Please read the notes on the back before filling out this page) -5 Printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs _Β2 ____ V. Description of the Invention (3) The Hubei has four major phases and is inherently dynamic. The problem of maintaining dynamic load surface tolerances in a split loop pipe lifter becomes quite onerous. On this pair of rings, axial load (thrust) or load on the circumference must be considered. The booster ring must They must be able to rotate with each other, and at the same time in relative positions, they must maintain tight control to ensure that the fluid channels and the compressor's final efficiency can be properly matched. In a split-loop booster, maintaining the required tolerances generally requires a very high cost. Another problem with split ring boosters is premature wear of the workpiece. Generally, it cannot be used in the air flow area of centrifugal compressors to exclude gas pollution. Due to the airflow flowing out of the impeller, the dynamic load imposed on the split-ring booster will wear out the booster element during acceleration without lubricant. A drive system capable of correctly positioning the rings with each other must, among all conditions, be sufficiently rigid to avoid any wear of the components. Due to the load on the circumference of the ring, the inner ring has a tendency to oscillate relative to the outer ring, which causes instability of the compressor and wear of the workpiece, and adversely affects the operating efficiency, resulting in several problems that must be overcome. Therefore, there is a need for a transmission system that can prevent the relative movement between the inner soil and the outer ring, as well as the concept of a bearing 'to allow relative rotation between the two rings, and to endure the circumference and thrust load while maintaining the tight geometric tolerances between the two rings. At the same time, it is also necessary to provide a niches system, including the correct minimum and maximum stops, to avoid unwanted noise and efficiency attenuation, and include simple field corrections. In addition, transmission and bearing systems need to have long operating life, as well as ease of installation and proper adjustment.

Description of the invention (10) Next refer to the coolant fluid under compression Occurred in the machine 10. The coolant enters the inlet opening 29 of the suction cover 3, passes through the blade ring assembly 32 and the guide vane 33, and then enters the compression suction area 23. This compression suction area forms a compression area, and the inner side is defined by the impeller 2 and its The outer side is defined by the cover 34. After compression 'the coolant flows into the booster 14, the collector 16 and the discharge line (not shown). According to the present invention ', a variable geometry pipeline booster 14 includes a first inner ring 40 and a second outer ring 42, a ring support mechanism 35 and a positioning transmission mechanism 121. Referring to Figures 3 and 4, the inner and outer rings have complementary fluid channel regions 44 and 46 formed therein. That is, each fluid passage region 44 'of the inner ring 40 has a complementary passage region 46 formed in the outer ring 42. The inner ring 40 and the outer ring 42 can rotate with each other. In a preferred embodiment, the inner ring 40 rotates around the circumference of a stationary outer ring 42. As shown in Figures 3 and 4, when a soil rotates relative to another ring, the alignment of each pair of complementary inflow channels of the inner ring and the outer ring changes. Rings 40 and 42 are adjustable between the first fully open position shown in FIG. 3 and the second partially closed position shown in FIG. 4. In the fully open position, the complementary channel regions are aligned, and the maximum amount of fluid passes through the inner and outer rings. 40 and 42, in the partially closed position, the complementary channels are out of alignment, thus restricting the fluid passing through the channel zones 44 and 46. A preferred embodiment according to the present invention 'Fig. 5 shows a ring support mechanism 35. Three such mechanisms are illustrated in the example, and are located on the circumference of the equally divided booster. Referring to FIGS. 6-7 'The ring supporting mechanism of the present invention includes an inner bearing slot 41 and a notch 43 in the inner ring 40, a roller assembly 5 4 and a roller assembly 3 6 and a Located in the outer ring outside the bearing slot 4 5. -13- This paper size is applicable to Chinese National Standard (CNS) A4 now (210X297mm) Walk and install ----- ..

In addition,' pull bolt 39 includes-pair with Concentric shoulders 73, 74 of the centerline of the inner hole of the shaft 50. Tit device: Another problem is the premature wear of the workpiece. There is almost no lubricating flow, and the dynamic load on the split booster is Without 's / brother, the booster components during acceleration will be worn. Because there is no lubricant in the shrinking machine, roughly some measures must be taken to reduce + friction and wear.-By the way, in the present invention, The specific example described below is that the component interface is often hard-coated. The workpiece is made of ultra-high polymer plastic material, the ring assembly is preloaded, and the backlash is eliminated by positioning the gears of the transmission system. Let ’s discuss the assembly and movement of the inner ring. The outer ring 42 is relatively stationary ^ The cover and two sets of round soil supporting mechanisms 35 are fixed by rolling The assembly 54 is in the bearing slot 45 of the outer ring, and passes the shaft through the fixing hole 58 and the roller "", and the shaft screw inspection 39 is passed through the shaft.

Description of the invention (13 A7 B7 Printed by the shellfish consumer cooperation department of the Central Standards Bureau of the Ministry of Economic Affairs ==, can be fixed on the outer ring 42, and The bearing plate will not accidentally contact the inner ring.-But if the outer cover 34 is installed, the main thread of the rotating thread will drive the bearing plate to contact the inner ring. With the bearing plate properly positioned, the lockable nut 94 can be tightened or loosened. In a preferred example, the bearing plate is made of a super-molecular-molecular plastic material. The invention of this invention—the real money, includes six such pumping directions): a gen-made mechanism, the outer circumference of the inner ring of the concrete is spaced equal to each other. In Fig. 10, a position transmission mechanism 121 for rotating the inner ring 40 on the circumference of the outer ring 42 is described. The inner ring 4G has been fixedly attached to the rack 123 extending radially outward from the inner ring 40. In the geared relationship, the rack is connected to the pinion 124 and driven by a starter 28 via the pinion shaft 126. The starter 128 is selected and controlled so that the inner ring 40 is moved relative to the outer ring 42 in the -first-full-open position and the second-part closed position, as well as any intermediate positions. Pinion # 126 outer cover-The outer cover is covered, and the pinion shaft 126 is sealed from the inner surface 132 of the compressor, and this outer cover 13 () also prevents the fluid in the compressor 10 from passing through the outer cover 30 &amp;.冷却 The coolant fluid in the booster, and the tangential and circumferential loads applied to the inner ring will cause the inner ring to tend to vibrate back and forth in the outer ring. Excessive movement or facial movement of the inner ring will wear the teeth 123 and the pinion gear 124 and cause other workpieces to wear. As discussed earlier, pre-loading the inner ring via the roller assembly prevents the inner ring from moving, as well as chattering under normal operating conditions. In abnormal conditions, such as when operating in a trembling state, an L-level mechanism is required to prevent movement of the inner ring. The present invention provides a transmission positioning system, which uses a shaft to cover the cover 130, and adjusts the relative center position between the pinion and the rack.

Description of the invention (15) In the fully open position, the fluid flow rate through the compressor 10 is about 0% to 100%. When the second part is in the closed position ( (Figure 4), at least about 10% of the fluid volume in the fully open position, will flow through the booster 14 to prevent excessive thermal heating process, noise, and reduction in compressor efficiency. As a result, the two ring sections rotate relatively The amount is limited by the amount of rotation required to make a second part closed position effective, that is, the two rings cannot be adjusted to completely close the fluid flow between them. The angle of rotation allowed between the two rings depends on the fully open position between the two rings The intended flow, and the number and volume of the inflow channel regions 4 4, 46 relative to the volume of the circular regions 40 and 42 in the circular regions 40 and 42. 4 'R2 defines the radius to the tip of the impeller, R3 defines the radius of the outer ring 40, and R4 defines the radius of the outer ring. The amount of the inner ring 40 is T = R3-R2, which defines the thickness of the fluid. It must not be too large, so as not to block the intended part of the fluid (for example, 50% of the fluid) passing through the outer channel 46, and the flow of the fluid through the booster 14. Can be effectively controlled. Before any pressure increase occurs, the rotation of the inner ring relative to the outer ring will reduce the throat area of the booster. This will prevent the fluid from accelerating after the pressure increase. Similarly, the smaller the inner ring thickness τ, the more the fluid passes through the partially closed position. The smaller the corner of the booster. Both effects mentioned above will improve compressor efficiency under partial load operating conditions. Referring to Figures 5 and 12, an example of the present invention is shown. A mechanism is provided to provide the inner ring with a correct position corresponding to a first fully open position and a second partially closed position. The cavity 137 is processed on the outer ring 42 towel, and can accommodate the rack 123. The rack ^ is accurately fixed to the inner ring 40 in a convex and concave manner, and the rack is provided with a two-shaped groove 143 adapted to receive the convex portion 139 of the inner ring 40.

Description of the invention (16) The ring is used to determine the fully open position, and the two rings are rotated relative to each other until the fluid channel 52 is completely connected with the outer fluid channel 46. If the two rings are in this position and the ring support mechanism is adjusted as described above, the rack is fixed to the inner ring, and the tooth surface 145 is in contact with the full open stop 14 of the cavity 137. At that time, install the screw check (Not shown) through the gear fixing hole 142, and fastened to the screw hole 138 in the inner ring. The rack and cavity have a size to provide a predetermined tightness of the tube booster. For example, in the present Invention-In a preferred embodiment, the cavity 137 is sized so that when the tooth surface 44 contacts the part of the cavity 37 and the stopper 14 1, the difference between the angular width of the rack and the angular width of the cavity reaches the opening position. In this example, the required stroke of the rack is degrees, the rack angular width is 35 degrees, and the corresponding cavity angle width is 45 degrees. You can use a bearing stop between the rack and the cavity to accurately and repeatably position the two bearing stops at the points corresponding to a fully open position and a partially closed position.

Each performance curve, such as 6 〇 is characterized by a flutter point, such as 70, which represents the maximum pressure that can be obtained. Operating a compressor at or below the flutter point may cause a facial motion condition, such as the background portion of the present invention In order to illustrate the present invention, for example, the curve 60 may correspond to the -th-total ----------- w clothes ---- * ~ ·-order ^ ------ line (Please read the precautions on the back before filling out this page} -19- Staff Consumption Cooperative of the Central Government Bureau of the Ministry of Economic Affairs, India 40 2666 V. Description of the invention (17) Open position 'Curve 6 2 may correspond to a partially closed position with a differential full open position of 2 degrees, Curve 64 may correspond to a partially closed position with a differential full open position of 4 degrees, and Curve 6 8 may correspond to a differential full open position Partially closed position at 8 degrees. It can be seen that 'adjusting the ring zones 40 and 42 to a closed position has the effect of adjusting the compressor performance curve, such as the vibration point of 70 and 72 to a lower flow rate. So By adjusting the booster ring 40 and 42 to the closed position, the chattering condition during low flow rate demand can be avoided. By comparing the performance chart of a compressor with a variable booster in FIG. In 14, the performance chart of a compressor with only adjustable inlet guide vanes is helpful to understand the present invention. In Fig. 14, the curves 80, 82, and 84 more 8 8 'correspond to the discontinuous positions where the guide vanes 3 3 are gradually closed. It can be seen that closing the guide vane 33 is similar to closing the booster ring regions 40 and 42 and has the effect of reducing the rate of facial movement. In this way, a tremor condition can be avoided by adjusting the inlet guide vanes 33 to the closed position. However, as can be seen from the performance chart of Fig. 14, adjusting the guide vane 33 to the "closed position" further has the effect of reducing the pressure head from the compressor 10 at the tremor point. Therefore, a low flow rate operating condition that requires a higher pressure cannot be satisfied by adjusting the guide vanes 3 3 alone. In comparison, 'the performance graph of Fig. 13' can be used to show that when the pressure booster rings 40 and 42 are adjusted to a closed position, the pressure at the vibration point from the compressor 10 can be kept stable. Therefore, a condition that requires a lower flow rate and a high compressor pressure to be sufficient for the operation condition 'can be satisfied by adjusting the booster ring 40 and 42 to the off position. -20- This paper size is applicable to Chinese National Standard (CNS) A4 now (210X297mm) --L --- r --- installation ------- order ^ ------ line ( Please read the notes on the back before filling in this page) Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs ^ ϋ, 6666ό Α7 ___ Β7 ___ V. Description of the invention (18) _ Relative to the full load operating pressure ratio (such as full load 9〇 %), Operating conditions that require a low flow rate to a high pressure ratio are common in general conditions. In this condition, 'Although the surrounding air temperature can vary significantly from room temperature (for example, about 50 ° F or more), there is only low load in the building that requires cooling. Therefore, although the refrigerant saturation pressure needs a higher compressor pressure ratio (for example, greater than about 2.5) for the concentrator and evaporation temperature, in a building, only a lower flow rate of full load, such as 25%, is required. To remove the heat generated. FIG. 15 shows a performance diagram of a compressor having an adjustable guide vane and a variable line booster in accordance with the present invention. It can be seen that the efficiency of a compressor can often be optimized by combining the adjustment of the guide vanes 33 and the booster rings 40 and 42. Referring to Fig. 15 ', the dotted line 1 1 1, π 2, 1 13, 1, 1 14, 1 15 and 1 1 6 shows the performance of a compressor with a variable booster at different positions of the inlet guide vanes 33 in the fully open position.

As known to those skilled in the art, when a compressor is operated at the &quot; turning point &quot; of the performance curve representing the performance of the compressor (as shown in Fig. 14-8), it can be regarded as having the best efficiency. Referring to FIG. 15, for example, a compressor operating according to the curve 104 has a maximum efficiency under an operating condition of 0.7 times the maximum pressure and 0.3 times the maximum flow rate. The device rings 40 and 42 are brought to a closed position, and the guide vanes 33 to 10 degrees are adjusted to complete.
