水泵转速过低

水泵转速过低
Pump speed too low
1、人为的因素。有相当一部分用户因原配电机损坏,就随意配上另一台电动机带动,结果造成了流量小、扬程低甚至不上水的后果。
1. Human factors. Because of the damage of the original electric motor, quite a number of users randomly equipped with another electric motor to drive, resulting in small flow, low head or even no water.
2、传动带磨损。有许多大型离心泵采用带传,因长期使用,传动带磨损而松驰,出打滑现象,从而降低了水泵的转速。
2. The drive belt is worn. There are many large centrifugal pumps with belt transmission, because of long-term use, the transmission belt is worn and loose, resulting in slipping, thus reducing the speed of the pump.
3、安装不当。两带轮中心距太小或两轴不太平行,传动带紧过安装到上面,致使包角太小,两带轮直径计算差错以及联轴传动的水泵两轴偏心距较大等,均会造成水泵转速的变化。
3. Improper installation. If the center distance between the two pulleys is too small or the two shafts are not parallel, if the drive belt is too tight and installed on it, the wrap angle is too small, the calculation error of the diameter of the two pulleys and the eccentricity of the two shafts of the water pump driven by the coupling are too large, the speed of the water pump will change.
4、自吸泵本身的机械橡胶托辊 槽型托辊 皮带托辊 平行托辊 保定搬家 保定搬家电话 保定搬家公司 保定搬家 铜鼎 铜狮子 故障。叶轮与泵轴紧固螺母松脱或泵轴变形弯曲,造成叶轮多移,直接与泵体磨擦,或轴承损坏,都有可能降低水泵的转速。
4. Mechanical failure of self-priming pump itself. If the fastening nut between the impeller and the pump shaft is loose or the pump shaft is deformed and bent, the impeller will move more, directly rub with the pump body, or the bearing is damaged, the speed of the pump may be reduced.
