1. Self-priming pumps are usually equipped with three-phase motors when they leave the factory. The users can connect to the 380V power supply and turn it to the correct position. (For single-phase motor, it should be stated when ordering that single-phase motor can only be connected to 220V power supply.)
　　
2. The pump must be filled with solution from the vented plug before it is used for the first time. Tighten the Rose, and then turn the sign, start the motor, according to different levels of suction generally takes 2 to 4 minutes, automatically exhaust the air, liquid delivery, the next start without dredging. Long-term unused pump start, you should first open the water Rose, check the pump for the presence of liquid, such as insufficient please make up.
　　
3. No self-priming pump pump body no liquid, start the motor, to prevent mechanical seal friction, fever burned.
　　
4. Mobile self-priming pump before the start, used in rotating the coupling, check whether the rotation flexibility, if the resistance is large, should identify the cause, after processing can be closed to start.
　　
5. After running, observe the sealing parts for leaks, if there is a slight leakage, allowing it to run 10 to 20 minutes, such as dynamic and static ring after the end of the run-in can be generally resolved, or should be removed one by one inspection, re-install.
　　
6. Conveying acid-rich slurry, water and rinse after parking to reduce the accumulation of acid, alkali liquid on the pump and pipe corrosion, in particular, to prevent the media precipitation in the seal ring, resulting in the next start bite ring.
　　
7. Mobile self-priming pump spindle and rotating parts should be kept clean, the bearing body to be added 2 to 3 times a year butter, the number of one to fill 40% of the butter chamber is appropriate.
　　
8. Pump supporting the motor, please note that moisture, corrosion, replace the motor, the new motor capacity and speed must be consistent with the original.
