Before starting the pump, fully open the suction and discharge valves.
1, for the first time to start the pump or re-use the long-term storage of the pump, should be injected into the liquid, with aids to rotate the shaft several times, so as not to damage the stator. Pump can not be no liquid start, no liquid start will damage the stator;
2, start the motor a moment, check the direction of rotation of the pump to confirm the same direction with the pump casing on the same direction before starting the run; 3, start the pump, observe the pressure gauge and vacuum gauge readings to meet the requirements, pay attention to pump sound, vibration Other operating conditions and found that abnormalities should be immediately stopped inspection;
4. During the initial start-up, fill the seal (especially PTFE, allowing for initial leakage, and adjust the nut evenly during the initial 15 minutes of start-up. Minimum leakage. If the stuffing box temperature rises sharply, the amount of leakage drastically reduced, immediately loosen the nut, repeat the above process;
5, the pump in normal operation, is by adjusting the speed to control the flow.
