Shijiazhuang Jinrun Stone Pump Machinery Technology Co., Ltd., as a manufacturer of dredging pumps in China, summarizes the following aspects that should be paid attention to during the use of dredging pumps.

1. Check whether the pipeline and connection of the dredge pump are loose. Turn the dredger pump by hand to see if the dredger is flexible.

2. Add bearing lubricating oil to the bearing body, the oil level should be observed in the center line of the oil mark, and the lubricating oil should be replaced or supplemented in time.

3. Remove the diversion plug of the dredging pump body and pour water (or slurry).

4. Close the gate valve and outlet pressure gauge and inlet vacuum gauge.

5. Start the motor and check whether the motor rotates correctly.

6. Start the motor. When the dredge pump is running normally, open the outlet pressure gauge and the inlet vacuum pump. When it shows the appropriate pressure, gradually open the gate valve and check the load of the motor.

7. Try to control the flow and head of the dredger pump within the range indicated on the label to ensure that the dredger pump operates under the most efficient conditions to obtain the maximum energy saving effect.

8. During the operation of the dredging pump, the bearing temperature shall not exceed the ambient temperature of 35 ℃, and the maximum temperature shall not exceed 80 ℃.

9. If the dredger is found to have abnormal sound, stop immediately to check the cause.

10. Regularly check the wear of the shaft sleeve, and replace it after the wear is large.

11. When the dredging pump is to be stopped, close the gate valve, pressure gauge, and then stop the motor.

12. After the first month of work, the oil of the dredge pump is changed 100 hours, and then the oil is changed every 500 hours

13. Regularly adjust the packing gland to ensure that the filling chamber of the container is normal (down drainage is appropriate).

14. The dredging pump is used in winter. After closing, the plug at the lower part of the pump needs to be removed and the medium discharged. Prevent cracking.

15. When the dredge pump is waiting for a long time, it should be disassembled and dried, and grease should be applied to the rotating parts and joints. Take good care of them.
