离心泵启动前的准备工作需注意_中国离心泵网_新浪博客

译文:
在启动离心泵之前需要注意以下几方面的事项: a.启动前检查 润滑油的名称、型号、主要性能和加注数量是否符合技术文件的要求; 轴承润滑系统、密封系统和冷却系统是否完好,轴承的油路、水路是否畅通; 盘动泵的转子1~2转,检查转子是否有摩擦或卡住现象; 在联轴器附近或皮带防护装置等处,是否有妨碍转动的杂物; 泵、轴承座、电动机的基础地脚螺栓是否松动; 泵工作系统的阀门或附属装置均应处于泵运转时负荷最小的位置,应关闭出口调节阀; 点动泵,看其叶轮转向是否与设计转向一致,若不一致,必需使叶轮xx停止转动后,调整电动机接线后,方可再启动。 b.充水 水泵在启动以前,泵壳和吸水管内必须先充满水,这是因为有空气存在的情况下,泵吸人口真空无法形成和保持。 c.暖泵 输送高温液体的泵,如电厂的锅炉给水泵,在启动前必须先暖泵。这是因为给水泵在启动时,高温给水流过泵内,使泵体温度从常温很快升高到 100~200℃,这会引起泵内外和各部件之间的温差,若没有足够长的传热时间和适当控制温升的措施,会使泵各处膨胀不均,造成泵体各部分变形、磨损、振动和轴承抱轴事故。

原文:
Centrifugal pump before you start to note the following aspects: a. pre-inspection Lubricants name, type, whether the number of the major performance and filling in line with the requirements of technical documents; Bearing lubrication system, sealing systems and cooling systems are intact, bearing the asphalt, water is smooth; Moving the pump rotor disk 1 ~ 2 turn, check whether there is friction or jammed rotor phenomenon; In the vicinity of the coupling or belt guards, etc., whether there is prejudice rotating debris; Pumps, bearing blocks, motor foundation anchor bolts is loose; Pump working system of valves or appurtenances shall be at the pump when the load of running the smallest position, should be closed outlet regulating valve; Jog pump, to see whether the design of the impeller turning turning consistent, if not, need to make a complete cessation of impeller rotation, the adjusting motor wiring only after the re-start. b. water-filled Pump start before the pump casing and suction pipe must be full of water, that is because of the presence of air, vacuum pumping the population can not be formed and maintained. c. warm pump High-temperature liquid transfer pump, such as the power plant boiler feed pumps must be warm before you start pumping. This is because when it starts to pump, heat pump to the water too, so that pump body temperature from room temperature quickly rose to 100 ~ 200 ℃, which can cause pump inside and outside and the temperature difference between the various components, if there is no long enough heat transfer time and appropriate temperature control measures, will pump around the expansion of inequality, resulting in deformation of pump parts, wear, vibration and bearing hold shaft accident.
