AY type single and two-stage centrifugal oil pump
AY type single and two-stage centrifugal oil pump series, is on the basis of the old Y type centrifugal oil pump series modification and redesign. It is to meet the needs of modernization, as soon as possible to adapt to energy saving centered equipment upgrading and development of new products.
Second, the purpose
1, the bearing body parts to the original 35,50,60 bearing body with 45,55,70 bearing body, improve the reliability.
2, hydraulic flow parts adopt the high efficiency and energy saving pump hydraulic model, the average is more efficient than the old Y type oil pump 5-8%.
3, to keep inheritance, AY type pump structure, performance, installation size parameters remain the same as the Y type oil pump, easy to old equipment renewal and reconstruction.
4, parts generalization degree is high, the general standard parts for several series of products share.
5, select material refining, the subject is given priority to with Ⅱ, Ⅲ materials, bearing body parts, such as increasing for cast steel, cast iron, for cold area of cold region, dew, outdoor use, Marine provides favorable conditions.
6, free bearing gas cooling and fan cooling, water cooling three, according to the different temperature of pump selection. The fan is especially suitable for cold and in lack of water or areas of poor water quality.
Three, model significance
Flow rate Q: 2.5 ~ 300 m3 / h
Lift H: 30 ~ 330 m
The temperature T: - 20 ℃ ~ + 300 ℃
