1. Check the multi-stage centrifugal pump pipeline and the combination of loose. Rotation of the multistage centrifugal pump with the hand, look at the multistage centrifugal pump is flexible.
2. To join the bearing lubrication oil bearing body, observe the oil level should be in the center line of standard oil, lubricating oil should be replaced or supplemented.
3.Water diversion plug of multistage centrifugal pump, screw, filling water (or lead paste).
4. Close the outlet valve and outlet pressure gauge and vacuum gauge.
5. Move the motor, when the motor turning right or not.
6. Multistage centrifugal pump long-term disabled, need to pump all apart, dry water, the combination of rotating parts and apply grease to pack.
7. As far as possible to control the flow and lift of the centrifugal pump in the range specified in the label, in order to ensure that the multi-stage pump in the highest efficiency point of operation, in order to obtain the maximum energy saving effect.
8. Multistage centrifugal pump in the running process, bearing temperature can not exceed the ambient temperature 35C, the maximum temperature shall not exceed 80C.
9. Such as the discovery of multi-stage l centrifugal pump abnormal sound should stop immediately check the reasons.
10. Multistage centrifugal pump to stop the use of the first to close the gate valve, pressure gauge, and then stop the motor.
11. Multistage centrifugal pump in the first month of work, replacement of oil by 100 hours, after every 500 hours, oil change time.
12. Multistage centrifugal pump often adjusting packing gland, packing room of the drip to ensure the normal situation (to drop out as appropriate).
13. Regularly check the wear of multistage centrifugal pump sleeve, wear in time after a larger replacement.
14. Multistage centrifugal pump used in the winter season, after stopping the pump body, lower drain plug unscrew medium on the net. To prevent cracking.
15. Start the motor, when the multi-stage pump after the normal operation, open the outlet pressure gauge and imported vacuum pump as it shows the appropriate pressure, and gradually open the gate, while checking the motor load.
