可以改变进、出口。方向的多级泵
(1)、检查多级泵管路及结合处有无松动现象。用手转动多级泵,试看多级泵
是否灵活。
(2)、向轴承体内加入轴承润滑机油, 观察油位应在油标的中心线处,润滑油
应及时更换或补充。
()、拧下多级泵泵体的引水螺塞,灌注引水(或引浆)。
(4)、关好出水管路的闸阀和出口压力表及进口真空表。
(5)、点动电机。试看电机转向是否正确。
(6)、多级泵长期停用，需将泵全部拆开,擦干水分,将转动部位及结合处涂
以油脂装好。
(7、尽量控制多级泵的流量和扬程在标牌上注明的范围内,以保证多级泵在
最高效率点运转,才能获得最大的节能效果。
(8)、 多级泵在运行过程中，轴承温度不能超过环境温度35C，最高温度不得
超过80C。

()、如发现多级泵有异常声音应立即停车检查原因。
(0、多级泵要停止使用时,先关闭闸阀、压力表，然后停止电机。
(1、多级泵在工作第一个月内 ,经100小时更换润滑油,以后每个500小时，
换油一次。
02、多级泵经常调整填料压盖，保证填料室内的滴漏情况正常(以成滴漏出
为宜)。
间、定期检查多级泵轴套的磨损情况,磨损较大后应及时更换。
网、多级泵在寒冬季节使用时,停车后,需将泵体下部放水螺塞拧开将介
质放净。防止冻裂。
(3)、 开动电机，当多级泵正常运转后,打开出口压力表和进口真空泵视其
显示出适当压力后,逐渐打开闸阀,同时检查电机负荷情况。

The import and export can be changed. Multi stage pump in direction
(1) check whether the pipeline and joint of multistage pump are loose. Turn the multi-stage pump by hand and try to see the multi-stage pump
Flexibility.
(2) add bearing lubricating oil into the bearing body, and observe that the oil level should be at the center line of the oil mark
It shall be replaced or supplemented in time.
(). Screw out the water plug of the multi-stage pump body, and fill the water (or slurry).
(4) close the gate valve, outlet pressure gauge and inlet vacuum gauge of the outlet pipe.
(5) jog the motor. Try to see if the motor turns correctly.
(6) if the multi-stage pump is out of service for a long time, it is necessary to disassemble the pump completely, dry the water, and paint the rotating parts and joints
Put it in grease.
(7. Try to control the flow and head of the multistage pump within the range indicated on the label to ensure that the multistage pump
The highest efficiency point operation can achieve the maximum energy saving effect.
(8) during the operation of multistage pump, the bearing temperature shall not exceed the ambient temperature of 35C, and the maximum temperature shall not exceed 35C.
More than 80C.
(). In case of abnormal sound of multistage pump, stop the pump immediately and check the cause.
(0. When the multi-stage pump is to stop using, first close the gate valve and pressure gauge, and then stop the motor.
(1. In the first month of operation, the multi-stage pump changes the lubricating oil after 100 hours, and then every 500 hours,
Change the oil once.
02. The packing gland of the multistage pump shall be adjusted frequently to ensure the normal leakage in the packing chamber (in order to leak out in drops
Suitable).
Check the wear condition of the multi-stage pump shaft sleeve regularly, and replace it in time when the wear is large.
When the network and multi-stage pumps are used in winter, the drain plug at the lower part of the pump body shall be unscrewed after shutdown
Quality released. Prevent frost cracking.
(3) start the motor. When the multi-stage pump is in normal operation, open the outlet pressure gauge and the inlet vacuum pump
After the appropriate pressure is shown, gradually open the gate valve and check the motor load.
