1. Check the self suction pump and the pipeline and the combination of the loosening of the phenomenon. Hand rotating self-priming pump self-priming pump, it is flexible.
2. To the bearing body join the bearing lubricating oil, to observe the oil level should be in the standard oil of the center line, the lubricating oil should be replaced or supplemented.
3. Water diversion plug pump self-priming pump screw, filling water (or lead paste).
4. Close the outlet pipe of the valve and the outlet pressure gauge and imported vacuum gauge.
5. Move the motor, when the motor turning right or not.
6. Start the motor, when the normal operation of the self suction pump, open the export pressure gauge and imported vacuum pumps, as it shows the appropriate pressure, gradually open the valve, and check the motor load.
7. As far as possible to control the flow and head of the self suction pump in the range of signs, in order to ensure the maximum efficiency of the pump in operation, to achieve the maximum energy efficiency.
8. Self priming pump in the running process, the bearing temperature can not exceed the ambient temperature of 35C, the maximum temperature shall not exceed 80C.
9. If it is found that the abnormal sound of the suction pump should be immediately stopped to check the reasons for.
10. Self priming pump to stop the use of the first to close the gate valve, pressure gauge, and then stop the motor.
11. Self suction pump in the first month of work, replacement of oil by 100 hours, after every 500 hours, oil change time.
12. Regularly adjusting packing gland, packing room of the drip to ensure the normal situation (to drop out as appropriate).
13. Regularly check the wear sleeve, wear in time after a larger replacement.
14. Self suction pump used in the winter season, after stopping the pump body, lower drain plug unscrew medium on the net. To prevent cracking.
15. Self-priming pump long-term disabled, need to pump all apart, dry water. The moving parts and combine apply grease to the installed, properly maintained
