AY type oil pump

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-support type, two-stage single-suction two-support type. The casing of this type of pump is radially split, the installation method is horizontal centerline support, the suction port and discharge flange of the pump are vertically upward, and the shaft seal can not only use soft packing, but also be interchangeable with the mechanical seal. The bearing body is equipped with a set of radial ball bearings and a set of thrust ball bearings installed back-to-back. The bearings are lubricated with thin oil. For the convenience of maintenance, it is not necessary to disassemble the suction or discharge pipeline. The elastic diaphragm coupling) can easily remove the impeller, bearing, bearing and other components.

Overview

◇ AY series centrifugal oil pump is modified and redesigned on the basis of old Y-type oil pump
◇ Bearing parts use 45, 55, 70 bearing bodies from the original 35, 50, and 60 bearing bodies respectively, which improves the reliability.
◇ The hydraulic model of the energy-saving pump is adopted in the hydraulic overflow part, which is 5~8% higher than the efficiency of the old Y-type oil pump on average.
◇ In order to maintain the inheritance, the structure, installation dimensions and performance parameters of the AY series oil pump remain the same as the old Y series oil pump, which is convenient for the renovation of the old device.
◇ High degree of generalization of parts and components, common standard parts are common to several specifications of products.
◇ The selection of materials is refined, the main body is mainly made of Class II and III materials, and the bearing body and other parts are increased to cast steel and cast iron, which provides favorable conditions for open-air use and marine use in cold areas.
◇ Bearings are air-cooled, fan-cooled, and water-cooled, which are selected according to different operating temperatures of the pump. Among them, fan cooling is especially suitable for areas with water shortage or poor water quality.
◇ Viewed from the motor side, it rotates counterclockwise
◇ Execution standard GB3215-82 and AP1610 (OH2)

●Parameter range
◇ Flow 2.5~600m3/h
◇ Head 30~330m
◇ Temperature -45~+420℃

●Scope of application
Mainly suitable for conveying clean, low or high temperature, neutral or corrosive liquids.

Mainly used in petroleum refining, petrochemical, chemical industry, oil field, oil and gas transportation and other fields.
