8、安装后拔动泵轴、叶轮应无磨擦声或卡死现象，否则应将泵拆开检查原因；
9、泵体进出口法兰按1.6MPa标准设计，所以配备时应相同规格。

1. Do not apply the pipeline weight on the pump in erection so as to prevent it from deformation;
2. Both pump and motor are integrally structured and no need of calibration on them in erection, so it is easy to mount;
3. Tighten the foot bolts in erection so as to avoid affecting the pump's performance due to the vibration at Starting;
4. Before erection, please carefully check if there is any hard matters (such as stones, iron dregs etc. ) inside of the pump's flowpath which would affect its running so as to prevent both impeller and pump casing from being damaged during running;
5. For the sake of convenient service and safe use, mount one regulation valve on both inlet and outlet pipelines of the pump and one piezometer near the outlet to guarantee it to run with in the rated head and flow quantity as well as to run normally and extend its dura-Bility;
6. The pump has to be mounted with a fot valve when used with suction stroke and the inlet pipeline should not be with too many hent-pathes and water or air leak-Age;
7. Iff order not to let foreign matters into the pump to cause the flow-path blocked and the per formance affected, mount a filter before the pump inlet which has a sectional area 3-4 times larger than that of the suction Pipe;
8. Move both pump shaft and impeller with hand after erection, with which there should be no frictional soun or jamming, otherwise the pump has to be removed for checking the causes;
9. The flanges on both inlet and outlet and outlet of the pump are designed per 1.6MPa standard and use the identical specs when to

起动与停车STARTANDSTOP

起动前准备

1、试验电机转向是否正确，从电机顶部往泵看为顺时针旋转，试验时间要短（点动），以免使机械密封干磨损；
2、打开排气阀使液体充满整个泵体，待满后关闭排气阀；
3、检查各部位是否正常；
4、用手盘动泵以使润滑液进入机械密封端面；
起动
1、全开进口阀门；
2、关闭出口管路阀门；
3、起动电机，观察泵运行是否正常；

Preparations before starting

1. Test the motor to see if it is in the correct direction, which is CW viewing form its top to the pump, and take a short-time test (by spot moving)
so as to avoid damage of the mechanical seal due to dry-wearing;:
2. Open the exhaust valve to let liquid full of the pump casing and then close it when full;
3. Check if every part is normal;
4. Move the pump with hah to let the lubricating liquid into the end face of the mechanical seal.

Starting

1. Fully open the inlet valve;
2. Close the valve on the outlet pipeling.
3. Start the motor to see if the pump runs normally;

4、调节出口阀门开度至所需工况，如用户在泵出口处装有流量表或压力表，应通过调节出口阀门开度使泵在性能参数表所列的额定点上运转，如果用户在泵的出口处没有安装流量表或压力表，应通过调节出口阀门度，使电机在额定电流内运行，否则将造成泵超负荷运行（即大电流运行）至使电机烧坏。调整好的出口阀门开启大与小和管道工况有关；

5、检查电机、轴承处温度 \lesssim70 {degree} 。

停车

1、关闭出口管路阀门；
2、停止电机；
3、关闭进口阀门；
4、如长期停车，应将泵内液体放尽。

4. Adjust the open-extent of the outlet valve and the desired working conditions. In case of the user who mounts a flow meter or piezometer on the pump outlet, it is necessary to adjust the open-extent of the outlet valve to let the pump run at the rated points listed in the performance parameter table. Measure the motor's current to have it run within the rated current. Otherwise the pump may be caused to run with an overload (that is running with a heavy current) to make the motor burnt out. The size of opening of the adjusted outlet valve is relevant to the working condition of the pipeline;

5. Check the temperature on both motor and bearing, which should be \lesssim70 ^\circC

Stopping

1. Close the valve on the outlet pipeline;
2. Stop the motor;
3. Close the inlet valve;
4. Drain out the liquid inside of the pump completely if not to use it for a ling time.

泵的维护MAINTENANCEOFTHEPUMP

运行中的维护与保养

1、进口管道必须充满液体，禁止泵在汽蚀状态下长期运行；
2、定时检查电机电流值，不得超过电机额定电流；
3、水冷套是个隔热冷却装置，严禁在高温运行时随意关闭冷却供水；
4、输送高温液体时严格遵守升温速度，以防止热冲击，保护泵及管路各密封面，防止高温液体喷出伤人；
5、泵进行工期运行后，由于机械磨损，使机组噪音及振动增大时，应停车检查，必要时可更换易损零件及轴承，机组大修期一般为一年；

机械密封维护与保养

1、机械密封润滑应清洁无固体颗粒；
2、严禁机械密封在干磨情况下工作；
3、起动前应先盘动泵（电机）几圈，以免突然起动造成石墨环断裂损坏；

Maintenance in running

1. The inlet pipeline must be full of liquid and prohibit the pump from running for a long time under the vapour-corrosion status;
2. Periodically check the current value of the motor and never let it over the rated one;
3. The water-cooling sleeve is a heat-isolation cooling device and prohibit the cooling water supply form being closed at willunder a high-temperature running;
4. Strictly follow the temperature rise speed when to transport high-temperature liquids to prevent against heat-shock and protect the sealed surface of both pump and pupeline to prevent high-temperature liquid from spraying out to injure people;
5. Stop and check it when both noise and vibration of the unit are found greater due to the mechanical wearing after the pump finishes the wori-period running and, if necessary, replace both easily worn-out parts and bearing. Generally the period for the unit to be overhauled is one year.

Maintenance of the mechanical seal

1. The lubricating liquid for the mechanical seal must be clean and without any solid grains;
2. Prohibit the mechanical seal from working with Dry-wearing;
3. Before starting, first move the pump )motor) several turns with hand so as to prevent the graphite ring from break-down and
