AY型单、两级离心油泵是在老Y型离心油泵系列的基础上进行改造并重新设计的。它是为满足现代化建设的需要，尽快地适应以节能为中心的设备更新换代而发展的新产品。AY型单、两级离心油泵用途1、轴承体部件将原35，50，60轴承体分别用45，55，70轴承体，提高了可靠性。2、水力过流部位采用了***节能泵的水力模型，平均比老Y型油泵的效率高5—8%。3、为保持继承性，AY型油泵的结构型式、安装尺寸、性能参数范围保持与Y型油泵相同，便于老装置更新改造。4、零部件通用化程度高，通标件为几个系列产品共用。5、选材精炼，主体以Ⅱ、Ⅲ类材料为主，轴承体等零部件增加为铸钢、铸铁两种，为寒冷地区、露冷地区、露天使用、船用提供了有利条件。6、轴承有空气冷、风扇冷、水冷三种，根据泵的不同使用温度选用。其***扇冷尤为适宜和于缺水或水质差的地区。三、型号意义流量Q：2.5～300m3/h扬程H：30～330m温度T：-20℃～+300℃AY型单、两级离心油泵性能性能参数型号流量Qm3/h扬程Hm转速nr/min效率η%汽蚀余量NPSHm轴功率PaKW配带电机泵重kg型号功率KW25AY401.5402950132.51.36YB90L-22.212525AY40×21.5802950122.43.28YB112M-2412532AY403402950182.51.9YB90L-22.212532AY40A2.7342950182.51.4YB90L-22.232AY40×23802950192.73.5YB132S1-25.515832AY40×2A2.7702950172.63.03YB112M-24.032AY40×2B2.4652950152.52.8YB112M-24.032AY40×2C2.2602950152.52.54YB112M-24.032AY603602950162.53.05YB112M-24.012532AY60A2.7532950152.52.6YB112M-24.032AY60×231202950143.07.05YB160M1-21116032AY60×2A2.71052950142.95.64YB132S2-27.532AY60×2B2.4902950132.84.51YB132S1-25.532AY60×2C2.2762950122.83.8YB132S1-25.540AY406402950302.52.35YB100L-2312540AY40A5.46342950302.51.7YB90L-22.240AY40×26.25802950312.74.4YB132S2-27.516340AY40×2A5.85702950312.73.6YB132S1-25.540AY40×2B5.4602950312.72.85YB112M-2440AY40×2C4.9502950312.72.17YB100L-2340AY606602950242.54.05YB132S1-25.513040AY60A5.58532950222.53.7YB132S1-25.540AY60×261202950352.45.62YB132S2-27.517040AY60×2A5.61032950342.44.7YB132S2-27.540AY60×2B5.4902950322.34.2YB132S1-25.540AY80×261602950203.513.1YB160L-218.517540AY80×2A5.461412950203.410.5YB160M2-21540AY80×2B5.11252950183.39.65YB160M2-21540AY80×2C4.11062950173.37.1YB160M1-21150AY6012.5702950422.95.67YB132S2-27.513050AY60A11.2532950392.94.1YB132S1-25.550AY60B9.9392950372.82.8YB112M-2450AY60×212.5120295037211YB160M2-21521050AY60×2A1210529503629.5YB160M2-21550AY60×2B11902950351.97.7YB160M1-21150AY60×2C10762950351.76YB160M1-21150AY8012.5802950312.58.8YB160M1-21112050AY80A12702950312.57.42YB160M1-21150AY80B11612950312.56YB132S2-27.550AY80×212.51602950312.517.4YB180M-22221550AY80×2A121412950312.314.9YB160L-218.550AY80×2B111232950302.312.3YB160M2-21550AY80×2C101052950302.39.55YB160M2-215)
