When using water pump set in spring, targeted maintenance and management should be carried out based on the characteristics of the spring climate, such as large temperature differences, high humidity, and increased thunderstorms, to ensure safe and stable operation. The following are key points to note:

1、 Spring maintenance and inspection of water pump set

Cleaning and Inspection

Clean the filter/mesh: In spring, there is a lot of sediment and debris, so it is necessary to clean the inlet mesh to prevent blockage.

Check sealing: Low temperatures in winter may cause aging of seals. Check for leaks at the water pump shaft seal and flange connection.

Pipeline inspection: Check whether the pipelines and valves that may freeze and crack in winter are damaged or corroded, and replace them in a timely manner.

Water pump set electrical system protection

Moisture and short circuit prevention: In spring, when the humidity is high, check the insulation performance of the motor and control cabinet, and clean the moisture or rust inside the junction box.

Grounding protection: Ensure reliable grounding of the motor and control cabinet to avoid the risk of electric shock during thunderstorm seasons.

Cable inspection: Check if the cable skin is cracked to prevent rainwater from penetrating and causing short circuits.

Lubrication and mechanical components

Replace lubricating oil: Change the lubricating oil suitable for spring viscosity according to temperature changes (such as replacing low-temperature oil in winter with universal oil for all seasons).

Bearing maintenance: Check the wear of the bearings, add or replace lubricating grease to avoid lubrication failure caused by temperature differences.

2、 Preparation before starting the water pump set

Water pump set no-load test: Disconnect the load before starting, idle for 1-2 minutes, and observe for any abnormal noise or vibration.

Direction confirmation: Check if the motor direction is consistent with the water pump label (reversing may damage the impeller).

Pressure and flow calibration: Spring water demand may change, adjust valve opening or frequency conversion parameters to avoid overload operation.

 

3、 Water pump set operation monitoring

Temperature rise monitoring:

The motor temperature shall not exceed the nameplate limit, and the bearing temperature shall be ≤ 70 ℃.

Abnormal heating may be caused by insufficient lubrication or excessive load, and the machine needs to be shut down for troubleshooting.

Vibration and noise:

Using a vibration meter for detection, exceeding the vibration value may be due to impeller imbalance, bearing wear, or loose foundation.

Water level and flow rate:

Spring water level fluctuates greatly, avoid dry running of the pump body.

4、 Water pump set flood and lightning protection measures

Flood prevention preparation:

Check the drainage system of the water pump set room to ensure that the accumulated water can be discharged in time during the rainstorm.

Pump stations in low-lying areas need to prepare flood control materials such as sandbags and water barriers.

Lightning protection:

Check if the lightning rod and grounding grid are intact. It is recommended to install surge protectors in areas with frequent thunderstorms.

 

5、 Water quality management

Anti blocking measures:

In spring, there is an increase in algae and weeds, and fine grids or trash nets can be installed at the inlet.

Regularly clean up any sediment that may accumulate in the water pump set pump chamber.

Anti corrosion treatment:

If transporting water containing corrosive substances, check whether the pump body material is corrosion-resistant.

6、 Emergency Plan for Water Pump Set

Spare parts reserve: Prepare vulnerable parts in advance.

Power outage response: Configure backup power or install power outage protection devices.

Fault drill: Organize emergency response training for sudden faults.

 

The important aspects of spring water pump unit management include moisture prevention, blockage prevention, flood control, and overload prevention. By regularly checking, adjusting operating parameters, strengthening monitoring, and emergency plans, seasonal failures can be avoided and equipment usage time can be extended.
