6分钟前 武汉油井泵空心转子货真价实「多图」[螺耐斯10e361c]内容：
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, 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.
3.泵在快速启动和高速运转过程中的震动明显减小。
3. Pump vibration iously decreases in the process of quick
start and high-speed operation.
4.设备运行过程中，噪音分呗大幅度降低，不会有噪音污染。
4. In the operation process of the equipment, noise decibel
is greatly lowered without noise pollution.
螺杆泵工作特点：结构简单、工作安全可靠、使用维修方便、出液连续均匀、压力稳定，噪声和振动小，有自吸能力，但螺杆加工较困难。
螺杆泵适用场合：①输送润滑油，输送燃油，输送各种油类及高分子聚合物，适用于输送黏稠液体。
②输送高粘度介质：根据泵的大小不同可以输送粘度从37000-200000厘泊的介质。
③输送含有颗粒或纤维的介质：颗粒直径可以这30mm（不超过转子偏心距）。纤维长可以350mm（相当0.4位转子的螺距）。其含量一般可达介质窖的40%，若介质中的固体物为细微之粉沫状时，含量可达60%或更高也能输送。
④要求输送压力稳定，介质固有结构不受破坏时，选用单螺杆泵输送为理想。
