Check whether the working pressure of the water heating blanket mattress water pump is out of range. There are mainly the following steps:

1. Understand the rated parameters of the water pump

- Check the manual or nameplate of the water pump to understand its rated head, flow, power and other parameters. These parameters are the normal working range of the water pump.

2. Measure the working pressure of the system

- Install a pressure gauge at the outlet of the water pump to observe the actual working pressure of the system.

- If the system pressure exceeds the rated head range of the water pump, it means that the pressure is too high.

3. Check the resistance of the system pipeline

- Excessive resistance of the system pipeline will also cause the working pressure of the water pump to exceed the range.

- The pressure drop of each section of the pipeline can be measured to find out the parts with greater resistance.

- Appropriately increasing the pipe diameter or cleaning the pipeline can reduce the system resistance.

4. Analyze whether the working condition of the water pump is appropriate

- Check whether the installation location and working environment of the water pump meet the requirements.

- If the water pump is improperly installed or the working condition is abnormal, it will also affect its working pressure.

5. Adjust or replace the water pump if necessary

- If the working pressure of the water pump is indeed out of range, you need to adjust or replace the water pump model accordingly.

- Choose a water pump model with a higher head, or adjust the system pipeline parameters.

In short, checking the working pressure of the water pump is an important means to evaluate its working status, and various factors should be systematically analyzed. I hope these steps will help you.
