TH111776A - Centrifugal compressor - Google Patents

Abstract

DC60 centrifugal compressors can be provided. Which gives the frequency of Noise caused by the rotation of the multiple blade propeller unit does not resonance with the Natural frequency of gas vibrations in multiple axial inlet chambers This offers the benefit of increasing the gas flow rate during the working flow rate. Of gas increases and thus a wider stable operating range during the The gas flow causes a reduction in noise caused by the rotation of the impeller set. An axial inlet is created between the peripheral parts of the casing inlet. Compressor by the peripheral surface of the inlet and the supporting casing ring part By many supporting pillars that extend from the surrounding surface Where four or more pillars Further, it will be provided to support all the rings and support columns except for the support posts. One post will be placed at a position which will be determined when all the support posts are placed at the span. Evenly spaced along the circumference And one of the support columns is shifted along the circumference of One of those positions to a certain center angle. Centrifugal compressors can be provided.

Claims (6)

1. Centrifugal compressor Which contains the following components Location cladding frame Stationary and a set of propellers that are supported by rotation in the casing With the cover Where the cover has an import way that has The diameter is larger than the diameter of the ring inlet area of the impeller unit. Several blades are directed outward along the upper radius, where each blade includes the leading edge, the trailing edge and the outer end, multiple inlet sockets. Built in the surrounding part of Inlet of the casing near the ring area Of the impeller set between the ring-shaped rings supported by several support pillars spanned along Axis, facing inward from the peripheral surface so that multiple inputs are Are separated by support columns and are arranged along a concentric circumference with a concentric axis. In the rotation of the impeller set, each end of the inlet is opened to the inlet at its periphery and the other end is opened to the gas flow of the impeller set. The outer end near the leading edge, through the ring-shaped slit behind the ring. Where four or more pillars are provided to support the ring section, provided that all support columns except one support post are placed in a position to be determined. When all support posts are placed at equal intervals along the circumference And one supporting pole It is placed in a circumferential position from one of the omitted positions. Such an even range to some concentric angles. 2. Centrifugal compressor according to claim 1, where the position will be Consider determining to place several support poles plus one support pole along the circumference Same distance And several pillars shall be placed in such a predetermined position, not including one such post so that the support posts would not be held at one of the Positions that are evenly spaced 3. Centrifugal compressor according to claim 1, where the ring part is supported. The pillars were received by 4 support poles, and one of them was placed at the position shifted along the waiting line. To the center angle that is equal to = ((180 / T) X (1/2 ~ 1/3)) from one of the positions. This was determined when all four support pillars were arranged at equal intervals along the circumference, where T is the total number of support posts. 4. Centrifugal compressor according to claim 1, where the ring part is supported. The pillars were received by 4 support poles, and one of them was placed at the position shifted along the waiting line. Bends to a central angle equal to 18 ํ from one of the considered positions When all four support pillars are arranged at equal intervals along the circumference, where T is the total number of support posts. 5. Compressor centrifugal according to claim 1, where the ring part is supported. The pillars were received by 5 or 6 poles, and one of them was placed at the shifting position. Circumference to the center angle equal to ((180 / T) X (1/2)) from one of the positions in which It is determined when all support columns are arranged at equal intervals along the circumference where T is the total number of support posts. 6. Centrifugal compressor according to claim 1, where the ring part is supported. The pillars were received by 7 support poles and one of them was placed at the right place. It moves along the circumference to a center angle that is equal to (180 / T) from one of the positions. This is determined when all the support posts are arranged at equal spacing along the loop, where T is the total number of support posts.
