Definitions
- Patent 1 Ehlinger Sept. 18, 1973 COMPRESSOR ASSEMBLY [75] Inventor: Arnold H. Ehlinger, Hales Corners,
- ABSTRACT An air compressor assembly including a centrifugal impeller discharging air through a vaneless diffuser and a plurality of conical diffusers into an air collecting plenum.
- An air cooler is connected to the open end of the plenum to receive the air therefrom.
- a more specific object of this invention is to provide a compressor assembly of the hereinbefore described type of reasonable size to permit the assembly to be utilized as a stage of a multi-stage compressor utilizing intercoolers.
- FIG. 1 is a cross sectional view of a compressor assembly constructed in accordance with this invention taken along thc line l--l of FIG. 2;
- FIG. 2 is a cross sectional view taken along the line ll-ll of FIG. 1.
- a centrifugal compressor impeller generally designated 6 is supported for rotation by a shaft 7.
- the impeller 6 is located within a compressor casing generally designated 8.
- Walls of the compressor casing define an annular vaneless diffuser 9 located about the radially outer end of the impeller 6.
- the inner ends of the conical diffusers are in air communication with the radially outer end of the vaneless diffuser 9.
- the discharge or larger end of the conical diffusers 11 are in air communication with a plenum generally designated 12.
- the plenum 12 is connected to the compressor casing 8 in any conventional manner and completely surrounds the discharge ends of the conical diffusers 11.
- One end of the plenum 12 is open to the inlet of an air cooler generally designated 13.
- One of the conical diffusers as shown in FIG. 1 discharges the air therethrough directly toward the intercooler. However, the remaining conical diffusers discharge the air therethrough at an angle from the inlet to the intercooler. Therefore, guide vanes 14 are provided at these three conical diffuser discharge openings to guide the discharged air into the air cooler intake.
- the compressor assembly above described, can be advantageously utilized as a single stage compressor or as a stage of a multi-stage compressor.
- the gas enters the compressor inlet 16 where the impeller 6 increases its internal and kinetic energy. About one-half of the work done by the impeller is in the form of kinetic energy.
- the gas After the gas leaves the impeller it flows through the vaneless diffuser 9 where a part of its kinetic energy is converted to internal energy producing an increase in static pressure.
- the gas At the outer diameter of the vaneless diffuser 9 the gas is collected and fed into the conical diffusers where there is a further conversion of kinetic energy and a further increase in pressure.
- the vaneless diffusers 9 would be required tobe much longer and would alsorequire a log spiral plenum resulting in a much larger assembly.
- the height of a compressor constructed in accordance with this invention would be approximately l5 percent less than the height of a compressor incorporating a vaneless diffuser and a log spiral plenum and having substantially equal capacities. A slight reduction in axial length of this compressor is also achieved.
- a decrease in the height of a compressor has decided benefits.
- the reduction in height of the lower half casing (from base to horizontal joint) makes that part easier to ship.
- the reduction in height of the upper half casing reduces the head room required for removal of the upper half casing during maintenance.
- inventions in which an exclusive property or privilege is claimed are defined as folintegral gas cooler located in said plenum and guide means about said circumferentially spaced conical diffusers for directing the discharge gas from said conical diffusers into said gas cooler.
