高速切线泵具有小流量和高扬程的特点,在化工厂应用非常广泛。我厂自罐区向裂解炉供应石脑油原料的供给泵即为该种类型泵。型号为Sondyne LMV-311,位号V-GA101A/B,一开一备。泵参数如下:流量50.5m~3/h,出口压力3.4MPa,泵转速10308r/min,电机功率125kW,转速2983r/min。为保证向裂解炉连续供料,当运行泵出口压力低于2.8MPa时,备用泵自启动向裂解炉供料。 该泵增速器为二级增速(见图1),电机与低速轴7通过挠
High-speed tangent pump with low flow and high lift characteristics, the chemical plant is widely used. I plant from the tank to the cracking furnace supply of naphtha feed pump is the type of pump. Model Sondyne LMV-311, location number V-GA101A / B, on the go. Pump parameters are as follows: flow 50.5m ~ 3 / h, outlet pressure 3.4MPa, pump speed 10308r / min, motor power 125kW, speed 2983r / min. In order to ensure continuous feed to the cracker, when the pump outlet pressure is lower than 2.8MPa, the standby pump starts to feed the cracking furnace. The pump gearbox for the two-speed growth (see Figure 1), the motor and the low-speed shaft 7 through the scratch
