空心转子优势:
Advantages of hollow rotor:
1.空心转子重量减轻后,与常规转子的轴向扭力减弱,启动扭矩降低,减速电机选型偏小,客户使用成本大大降低,达到环保节能效果。
1. After the weight of the hollow rotor decreases, the axial
torsion of conventional rotor will recede, break-out torque will lower,空心转子, gear
motor type will be relatively small, as well as customer's use cost will
greatly lower with effect of environmental protection and energy saving
obtained.
2.因摩擦力与重量有密切关联,因此与同等实心转子对比,重量减轻后,泵在运行过程中转子摩擦力减弱,使用寿命同比增大。
2. Because the force of friction is closely related to
weight, the force of friction of the rotor lowers and service life increases on
a year-on-year basis in the operation process of the pump after the weight1
decreases in comparison to the equivalent solid rotor.
单螺杆泵的选型要点1.单螺杆泵的压力确定: 单螺杆泵输出压力是根据衬套级数即衬套的导程数来确定: 1级:工作压力为0.6 MPa; 2级:工作压力为1.2 MPa; 4级:工作压力为2.4 MPa; 由于输送介质情况不同,3qgb螺杆泵对于含有严重磨损性的介质,请参照表一选择衬套级数。表一:根据介质的磨损性选择衬套级数 磨损性 一级 二级
