Universal housing for a centrifugal gas compressor
A universal housing for a centrifugal gas compressor is disclosed. The universal housing includes a body, a suction port extending from the body, a discharge port extending from the body, and a first compartment within the body. The first compartment includes a suction inlet in flow communication with the suction port and a discharge outlet in flow communication with the discharge port. The first compartment is configured to receive more than one staging length for the staging. The staging inlet is in flow communication with the suction inlet and the staging outlet is in flow communication with the discharge outlet.
1. A centrifugal gas compressor, comprising:
a housing including a body with a center axis;
a first compartment including:
a suction inlet formed in the body,
a discharge outlet formed in the body axially spaced apart from the suction inlet and including a discharge outlet width, wherein the discharge outlet being a slot extending on the inner circumferential surface of the housing, and
a first compartment length being, an axial length between and including the suction inlet and the discharge outlet;
compartment staging located within the first compartment, the first compartment staging including a staging inlet in flow communication with the suction inlet, a staging outlet in flow communication with the discharge outlet, and
a staging length extending from the staging inlet to the staging outlet, where the discharge outlet width is at least fifteen percent of the compartment length;
a second compartment within the body located adjacent the first compartment, the second compartment including:
a second suction inlet formed in the body, wherein the second suction inlet is a circumferential slot extending on the inner circumferential surface of the housing,
a second discharge outlet spaced apart from the second suction inlet;
a second compartment length being a second axial length between and including the second suction inlet and the second discharge outlet;
an endcap located adjacent the compartment staging and at least partially within the housing; and
a stator spacer located adjacent the endcap and configured to locate the compartment staging within the housing.
2. The centrifugal gas compressor of claim 1 , wherein the discharge outlet width is configured to receive more than one staging length, a variation in the staging length being from fifteen percent to forty percent.
3. The centrifugal gas compressor of claim 1 , wherein the discharge outlet width is from 10.16 centimeters to 25.4 centimeters.
4. The centrifugal gas compressor of claim 1 , wherein the body includes a suction end and a discharge end, and wherein the second discharge outlet is located between the discharge end and the second suction inlet, the suction inlet is located adjacent the second discharge outlet and between the second discharge outlet and the discharge end, and the discharge outlet is located between the suction outlet and the discharge end.
