、起动前要把泵和现场清理干净； 、检查托架内润滑油量是否适量 油量在油位计中心线 左
右 ，油位计是否完好； 、未接联轴器前检查原动机的转向，与泵的转向箭头一致后
从电机端看，叶轮顺时针旋转 ，接好联轴器； 、在装好机械密封 或填料 和联轴器后可轻便地用手转动泵轴，
应无摩擦现象，并将联轴器和防护罩安装好； 、泵在有吸程情况下使用，起动前应灌泵或抽真空；泵在倒灌
情况下使用，起动前应用所输送液将泵灌满，驱除泵中的空气后， 将吐出管的闸阀关闭； 、起动前检查基础螺栓有无松动，压盖是否歪斜，以及润滑油
和冷却水的供应情况；
、关闭进出口压力 或真空 表和出水阀门、 如有旁通管，此时
也应关闭 起动电机 最好先点动、确认泵转向正确后，才开始正式
运行 ，然后打开进出口压力 或真空 计，当泵达到正常转速，且仪
表指出相应压力时，再慢慢打开出水阀门，调节至需要的工况。在
吐出管路关闭的情况下，泵连续工作时间，不能超过 分钟； 、起动过程中要时时注意原动机的电流读数及泵的振动情况； 、密封情况：机械密封应无泄漏、发热现象，填料密封应呈连
续滴流状态。
、经常检查和电机的发热情况 轴承的温度不应超过 ℃ 及油
位计油面情况。 一般每运行 小时后，要全部更换润滑油一次 ； 、不能用吸入阀来调节流量，避免产生汽蚀； 、泵不宜在低于 设计流量连续运转，如果必须在该条件下
连续运转，则应在出口外安装旁通管，排除多余的流量； 、注意泵运转有无杂音，发发现异常状态时，应及时消除或停
车检查。
、缓慢关闭吐出管路闸阀 如果泵在倒灌情况下使用，还要关
闭吸入管路的闸阀 ，并关闭各种仪表的开关； 、切断电源； 、如果密封采用外部件引液时，还要关闭外引液阀门； 、如果环境温度低于液体凝固时，要放净泵内的液体，以防
冻裂； 、如果长时间停车不用，除将泵内的腐蚀性液体放净外，各零
件应拆卸清洗干净，尤其是密封腔，最好是将泵拆下清洗后重新装
好，除涂油防锈处理和封闭泵进、出口外，还应定期检查。

. 1. Please clean pump and working spor before driving; 2. Check lubricant oil proper or not (oil surface is about central line 2mm on
oil meter) and oil meter perfect or not;
3. Before connect coupling should check the rotating direction of motor, the
rotating direction should same as rotating direction of pump(looded from end of motor, impeller rotate as clockwise);
4. After install mechanical seal(or packing) and coupling, it can easily manual
rotate shaft of pump and with no attrition phenomenon, then install safe cover of
coupling; 5. When pump use under condition of suction process, should irrigate pump
or deflate vacuum before drive, pump use under the condition of flow backward
should fill full of pump before drive, after get rid of the air in the pump, please shut off the gate valve of dischange tube. 6. Check foundation bolt loosen or not before drive, check stuffing gland whether crooked or not and supply status of lubricant oil and cooling water.
. 1. Shut off pressure meter on inlet and outlet (or vacuum) and outlet valve
(any bypass tube should be shutted off either) drive motor (had better start in advance, confirm correct rotating direction to operate), then open outlet pressure meter (vacuum), when pump reach to normal rotating speed and instrument to
corr esponding pressure, slowly open outlet valve and adjust to demanded working
status. Under the condition of dischange pipeline being shutted off, continuous work time of pump can`t exceed 3 minutes; 2. In process of operation it should pay attention to eletric currency digit of motor and vibration status of pump from time to time;
3. Sealing status: mechanical seal shouldn`t have leakage, heating phenomenon, packing seal should be in continuous trickling stauts.
. 1. Constantly check heating circumstance of pump and motor (temperature of
bearing should`t exceed 75 ) and oil meter without oil surface status (generally,
it should replace lubricant oil once after every 1500 hours); 2. Shouldn`t use suction valve to adjust capacity, prevent generating air erosion; 3. Pump cannot operate continuously lower than 30% design capacity, if it has
to operate under such condition, must install by pass pipe to get rid of unnecessary
capacity; 4. Pay attention to the noise of operation of pump, if discover any abnormal
state, please eliminate or stop operating timely.
. 1. Slow close dischange nozzle pipeline gate valve, and close switch on various
instrument; 2. Switch off electric power;
3. If seal utilize outside pilot liquid, need to close outside pilot liquid valve; 4. If environmental temperature is lower than liquid freezing point, please drain out liquid cleanly to prevent being splitted; 5. If beposit if for a long time, please drain out corrosive liquid in pump clearly,
disassemble and clean each part, especially the seal cavity. Had better reassemble
it after cleaness, cover with antirust oil and block outlet and inlet of poum, besides,
it should be inspected periodically.
