AY type oil pump is divided into two structural forms: single stage single suction cantilever type, two stage single suction cantilever type, single stage double suction cantilever type, single stage double suction two supporting type, two stage single suction two supporting type. The pump shell is radial split, the installation method is the horizontal centerline support, the pump suction inlet and discharge flange is vertical upward, the shaft seal can not only use soft packing, but also exchange with the mechanical seal. The bearing body is equipped with a set of centripetal ball bearings and a group of back-to-back thrust ball bearings. The bearings are lubricated with thin oil. In order to facilitate maintenance, the impeller, bearings, bearings and other parts can be easily removed without disassembling the suction or discharge pipeline by using the elastic pillar pin lengthened coupling (which can also be matched with elastic diaphragm coupling).

An overview of the

AY series centrifugal oil pumps are modified and redesigned on the basis of the old Y-type oil pumps

The original 35, 50 and 60 bearing bodies are respectively used 45, 55 and 70 bearing bodies for the bearing parts, which improves the reliability.

The hydraulic flow-over part adopts the hydraulic model of high efficient energy saving pump, which is 5~8% higher in efficiency than the old Y-type oil pump on average.

In order to maintain the inheritance, the structural form, external installation size and performance parameter range of AY series oil pumps are the same as those of the old Y series oil pumps, which is convenient for the renewal and transformation of the old equipment.

High degree of universality of parts, general standard parts for several specifications of products common.

The material selection is refined. The main body is made of 2 and ferrous materials. The bearing body and other parts are increased into cast steel and cast iron, which provides favorable conditions for open-air use and Marine use in cold areas.

Bearing air cooling, fan cooling, water cooling, according to the different use temperature of the pump. Among them fan cooling is especially suitable for water shortage or poor water quality areas.
