  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，必需使叶轮完全停止转动后，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。

Pump before the start of the preparatory work should pay attention to Before starting the pump to note the following aspects of the matter: a. check before the start of Lubricants name, type, number of major performance and filling the requirements of compliance with technical documentation; Bearing lubrication system, sealing system and cooling system is intact, bearing oil, water is smooth; Moving the pump rotor disc 1 or 2 switch, check whether there is friction or stuck rotor phenomenon; The vicinity of the coupling or belt guards, etc., whether debris obstructs the rotation; Pump, bearing, motor foundation bolt is loose; Valve or pump attachment system should be running at the pump location of the minimum load, export control valve should be closed; To move the pump to see whether the design of steering wheel turned to the same, if not, must make a complete stop rotating impeller, the adjustment of the motor wiring, before re-start. b. water-filled Before starting the pump, the pump casing and suction pipe must be filled with water, this is because the presence of air, a vacuum pump can not develop and maintain the population. c. heating pump Heat transfer liquid pumps, boiler feed pumps, such as power plants, must be warm before starting the pump. This is because when it starts to pump, heat to flow through the pump, the pump body temperature rises rapidly from room temperature to 100 ~ 200 ℃, which will cause the pump inside and outside and the temperature difference between the various components, if not long enough heat transfer time and the appropriate measures to control the temperature rise will lead to uneven swelling around the pump, causing pump parts deformation, wear, vibration and bearing axle accident.
