1, the bearing member bearing the original 35,50,60 45,55,70 bearing body member, respectively, to improve the reliability. 2, hydraulic parts used over current hydraulic model of energy efficient pumps, on average 5-8% higher than the old Y-type oil pump efficiency. 3, in order to maintain the inheritance, AY-type oil pump structure type, installation size, performance one, AY, Y-type single-stage centrifugal pumps, AY AY-type oil pump Overview single, two-stage centrifugal pump series, is in the old Y-type centrifugal pump series on the basis of the transformation and re-design. It is designed to meet the need of modernization, as soon as possible to adapt to the energy-centric equipment replacement and development of new products. Two, AY, Y-type single-stage centrifugal pumps, AY pump uses a bearing member of the original bearing body 35,50,60 45,55,70 bearing body were used to improve the reliability. 2, hydraulic parts used over current hydraulic model of energy efficient pumps, on average 5-8% higher than the old Y-type oil pump efficiency. 3, in order to maintain the structural pattern of inheritance, AY-type oil pump, installation size, performance parameters to maintain the same Y-type oil pump for easy upgrading old equipment. 4, the high degree of component commonality, through standard pieces for several series of products are shared. 5, selection refining, subject to Ⅱ, Ⅲ class-based materials, bearings and other parts of the body to increase as steel, cast iron two kinds of cold areas, cold areas exposed, open-air use, providing favorable conditions for marine. 6, bearing air cooling, fan cooling, water-cooled three, depending on the operating temperature of the pump selection. Wherein the fan is particularly suitable for cold and lack of water or poor water quality in the region. Three, AY, Y-type single-stage centrifugal pumps, AY pump model significance flow Q: 2.5 ~ 300m3 / h Head H: 30 ~ 330m temperature T: -20 ℃ ~ + 300 ℃ Shijiazhuang, Hebei pump source Pump Co., Ltd. mainly produce ZJ , ZJL series slurry pumps and M, AH, HH type slurry pump, while the supply of all types of clean water pumps, centrifugal pumps, mud pumps, pulp pumps, vortex pumps, sewage pumps, and nearly 70 types of widely used municipal construction, irrigation, power generation, petrochemical, metallurgy, mining, fire protection, food, shipping, pharmaceutical and textile and other fields.
