What to do if the stainless steel submersible pump bearing is damaged
When the bearing of a stainless steel submersible pump is damaged, the following steps can be taken to solve the problem:
1. Determine the bearing damage
First, it is necessary to determine the specific situation and extent of the bearing damage. You can make a preliminary judgment by observing the operating status of the submersible pump, listening to the sound, measuring the vibration, etc. If the submersible pump has abnormal vibration, increased noise, increased temperature, etc. during operation, it may be a sign of bearing damage.
2. Shutdown inspection
Once it is found that the bearing may be damaged, it should be shut down immediately for inspection. Before shutting down, make sure that the submersible pump has been powered off and the relevant valves are closed to prevent accidents. After shutting down, you can disassemble the submersible pump casing to check the wear and lubrication status of the bearing.
3. Replace the bearing
If it is confirmed that the bearing is damaged, it needs to be replaced in time. The following are the steps to replace the bearing:
Prepare tools: Prepare the tools needed to disassemble and install the bearing, such as wrenches, screwdrivers, bearing removers, etc.
Remove the old bearing: Use special tools to remove the old bearing from the shaft. During the disassembly process, pay attention to protect the shaft and bearing seat from damage.
Clean the bearing seat: clean the oil and impurities in the bearing seat, and ensure that the inner surface of the bearing seat is clean and free of impurities.
Install the new bearing: install the new bearing on the shaft in the correct direction and position. During the installation process, ensure that the bearing fits tightly with the shaft and the bearing seat without looseness.
Filling lubricating oil: according to the instructions of the submersible pump, fill the bearing with an appropriate amount of lubricating oil to ensure the normal operation of the bearing.
4. Inspection and testing
After replacing the bearing, the submersible pump needs to be fully inspected and tested to ensure that it resumes normal operation. The inspection content includes but is not limited to:
Check whether the motor wiring of the submersible pump is correct, and whether the voltage and current are normal.
Check whether the sealing performance of the submersible pump is good and there is no leakage.
Start the submersible pump for trial operation and observe whether its operating status, vibration and noise are normal.
5. Maintenance
In order to avoid bearing damage again, the submersible pump needs to be maintained regularly. The maintenance content includes:
Regularly check the lubrication of the bearing and add or replace the lubricating oil in time.
Clean the debris and dirt inside the submersible pump to keep it clean.
Check the sealing performance of the submersible pump to ensure there is no leakage.
Regularly check whether the motor and cable of the submersible pump are intact and free of damage or aging.
