The maintenance of flood control water pump is an important guarantee to ensure their normal operation and effective drainage at critical moments. The following are the key points to pay attention to when maintaining flood control water pumps, summarized as follows:
1、 Daily maintenance and inspection of flood control water pumps
Appearance and connection inspection
Cleaning and anti-corrosion: Regularly remove dust, oil stains, and debris from the surface of the water pump to keep it clean. Check for corrosion, cracks, or deformation on the water pump casing, and promptly address any issues.
Tightening connection: Check whether the foundation bolts, inlet and outlet flange bolts, and other connection parts of the water pump are tightened to prevent looseness that may cause water leakage or vibration.
Electrical system inspection of flood control water pump
Cable and wiring: Check whether the cable is damaged or aged, whether the wiring is firm, and ensure good electrical connection.
Motor status: Check the insulation resistance, grounding resistance and other parameters of the motor to ensure that it is in good condition.
Inspection of mechanical components of flood control water pump
Bearing lubrication: Check the lubrication condition of the bearings, regularly add or replace lubricating oil to ensure smooth operation of the bearings.
Impeller and shaft: Check whether the impeller is worn, cracked, or deformed, and whether the shaft is bent or worn. If so, repair or replace it in a timely manner.
2、 Monitoring and adjustment of flood control water pump operation
Monitoring of operating parameters
Flow and head: Monitor the flow and head of the water pump to ensure it meets flood prevention requirements.
Temperature and vibration: Check the temperature and vibration of the water pump, and promptly shut down for inspection if any abnormalities are found.
adjustment and optimization
Adjust according to water level: Adjust the operating parameters of the water pump in a timely manner based on changes in water level during the flood season to ensure drainage efficiency.
Optimize operation mode: Based on the performance of the water pump and flood prevention requirements, optimize the operation mode of the water pump, such as using intermittent operation, parallel operation of multiple water pumps, etc.
3、 Regular maintenance and repair of flood control water pumps
Regular maintenance of flood control water pumps
Replace vulnerable parts: Regularly replace vulnerable parts of the water pump, such as seals, bearings, etc., to ensure the sealing and smooth operation of the water pump.
Cleaning and rust removal: Regularly clean the dirt and rust inside and outside the water pump to maintain its cleanliness and appearance.
Professional maintenance
Fault diagnosis: When the water pump malfunctions, it should be stopped for inspection in a timely manner, and professional maintenance personnel should be contacted for fault diagnosis and repair.
Maintenance records: Establish a maintenance record file to record the time, content, and replaced parts of each maintenance, facilitating subsequent maintenance and troubleshooting.
4、 Storage and Preservation of Flood Control Water Pumps
Storage environment
Dry and ventilated: The water pump should be stored in a dry and well ventilated place to avoid moisture and corrosion.
Keep away from fire sources: The storage location should be kept away from fire sources and flammable and explosive materials to ensure safety.
Custody measures
Regular turning: For water pumps that have not been running for a long time, they should be turned regularly to prevent shaft deformation.
Protective measures: For vulnerable components, protective measures should be taken, such as installing protective covers, applying rust proof oil, etc.
5、 Special environmental precautions for flood control water pumps
Pre flood inspection of flood control water pumps
Before the flood season, the water pump should be thoroughly inspected and maintained to ensure that it is in good condition.
Check if the inlet and outlet pipelines of the water pump are unobstructed, and if the valves are flexible and reliable.
Flood season operation monitoring
During the flood season, monitoring and inspection of the water pump should be strengthened to ensure its normal operation.
Any abnormal situation should be dealt with promptly to prevent the accident from escalating.
