40AY40 * 2A-type oil pump series is to transform the original Y-type oil pump series based on the re-designed. It is a new product to meet the needs of modernization and to adapt more quickly to the center of energy saving equipment replacement and development, and has the following characteristics: 1, the bearing member bearing the original 35,50,60 respectively 45, 55 , instead of bearing body 70, to improve the reliability. 2, hydraulic flow components using a hydraulic model of energy-efficient, the average than the original Y-type oil pump efficiency by 5-8 percentage points. 3, in order to maintain continuity, 40AY40 * 2A-type oil pump structure type, installation size, performance parameters to maintain the same Y-type oil pump for easy upgrading old products. 4, parts common programming high-standard pieces of several products share. 5, the choice of refined, mainly in Ⅱ, Ⅲ class-based materials, bearings and other parts of the body to increase the steel, cast iron two kinds of cold areas, outdoor use, provided the conditions for marine. 6 bearing air cooling, air-cooled, water-cooled three kinds, the choice depending on usage and temperature of the pump. Which is particularly suitable for water-cooled or water quality in poor areas. 40AY40 * 2A-type oil pump can be used in refined petroleum, petrochemical and chemical industries and other conveying solid particles of oil, liquefied petroleum gas and other media. 40AY40 * 2A-type oil pump parameters: Flow rate Q: 5.85m3 / h Head H: 70m 40AY40 * 2A-type oil pump structure type: 40AY40 * 2A-type oil pump structure is divided into six forms: single-stage single-suction cantilever, two single-suction cantilever, single-stage double-suction cantilever, single-stage double suction two-supporting, two pairs of suction two-supporting, two single-suction two-supporting. The pump casing is radially split, installation of horizontal centerline supported pump suction flange is vertically upward and exclusion, it can not only be soft packing seal and mechanical seal interchangeable. Thrust ball bearing body is equipped with a set of radial ball bearings and a set of bearings mounted back to back, bearing with oil lubrication, for easy maintenance, without dismantling the suction pipe or exclude, use the flexible pin spacer coupling (also with flexible diaphragm coupling) can be easily removed the impeller, bearings, shaft seals and other components.
