AY Centrifugal Oil Pumps

Introduction:

AY oil pumps are revised and redesigned basing on the old Y type oil pump. The series centrifugal pump completely conforms to API610 standard, the pumps are applied in petroleum refinery, petrochemical, chemical industry, and the applications which pump the petroleum and its products.

Performance:

Applications:

Petroleum industry 

Chemical industry

Power plant

Coal process industry

Structural Features:

The AY type oil including: single-stage and single-suction, double-stage and single-suction overhung pump two-stage and single-suction between bearing.

The casing is adopted radial split strcture, which is used to pump the medium under the high temperature and pressure, or inflammable, explosive and toxic fliud. The mounting type is horizontal centerline support.

The impeller is cast entirely and balanced, the xial force of pump is balanced hole.

The bearing is composed of ball bearing in radial direction and thrust ball bearing which is mounted back to back, the bearing is lubricated by liquid oil, the radiator is cast on outside surface of bearing body, it could be cooled by air(T＜120℃), fan(T=120℃~260℃) and water(T=260℃~420℃). 

The lengthened couplings with diaphragm would be used, in order to not dismantle the suction and discharge pipelines, and it is easy to dismantle the impeller, shaft, bearing, and shaft seal during the overhaul time.

The pump rotation direction is CCW viewing from driving end.
