The grounding protection should be intact

Control the valve to adjust the pump flow and pump outlet pressure. At the same time, open the vent valve of the filter tank before the pump to vent until the liquid is visible, then close the vent valve (or open the vent plug on the top of the pump to vent). Lubricating oil or grease, if the grease is qualified, the oil level should be between 1/2-3/4, and the grease should be added as required. Check the electrical equipment, the grounding protection should be intact, and the three-phase insurance should be intact. 6. 5. 6. Press the start button to decrease the current from the highest value. 5.

If the pump is stopped for a long time, the residual liquid in the pump must be drained to avoid rusting or freezing the pump body. Vertical pipeline pump start-up and operation inspection 1. 4. If the motor or pump bearing smokes, stop the pump immediately. 4. The disc pump has 5 to 6 revolutions,

which should rotate flexibly and without noise. 2. Carefully observe the changes in pump pressure and current to confirm that the motor is working normally. 4. 5. Start the motor, and confirm that the rotation of the motor is consistent with the specified direction. Open the inlet and outlet valves of the pump to fill the pump with liquid. 3. Check various instruments, check the working conditions of voltmeter and ammeter, and check the pressure gauge of pump inlet and outlet. Close the inlet and outlet valves of the pump. Vertical pipeline pump stops the pump 1.

Check whether the pump oil level is within the specified range. 3. Press the stop button to stop the pump. 2. 3. If the unit experiences strong vibration or the pump responds abnormally, China JET pumps factory stop the pump immediately. After the pump pressure rises and stabilize, slowly open the outlet valve. If the current exceeds the rated value, stop the pump immediately to avoid burning the motor. 2. Remove debris around the pump and tighten the fastening screws of each part.2020-03-27Preparation before starting the vertical pipeline pump 1
