How to read geothermal pressure gauge
The geothermal pressure gauge is an indispensable monitoring tool in the geothermal heating system. It can directly reflect the operating status of the system. This article will introduce in detail how to view the geothermal pressure gauge, and provide you with a practical guide based on the hot topics on the Internet in the past 10 days.
1. Basic structure of geothermal pressure gauge
Geothermal pressure gauge usually consists of dial, pointer, scale unit and connection interface. The pressure value is marked on the dial, and the pointer points to the current pressure value. Common units are MPa (Megapascal) or Bar (Bar).
| Part name | Function description |
|---|---|
| Dial | Display pressure value range |
| pointer | Indicates current pressure value |
| scale unit | Mark the pressure unit (MPa/Bar) |
| Connection interface | Connect to piping system |
2. How to correctly read the geothermal pressure gauge
1. Confirm the pressure unit: First check whether the dial is marked MPa or Bar. 1MPa≈10Bar.
2. Observe the position of the pointer: the scale pointed by the pointer is the current system pressure.
3. Determine the pressure range: The normal working pressure of the floor heating system is usually between 0.15-0.3MPa.
| Pressure range (MPa) | System status |
|---|---|
| 0-0.1 | Pressure is too low, need to replenish water |
| 0.15-0.3 | normal working range |
| 0.3-0.5 | High pressure |
| >0.5 | The pressure is too high and needs to be relieved |
3. Recently popular issues related to floor heating
According to search data from the entire Internet, the floor heating issues that users are most concerned about in the past 10 days include:
| Popular questions | search index |
|---|---|
| How to read floor heating pressure gauge | 8,500 |
| Reasons for sudden drop in floor heating pressure | 6,200 |
| Best pressure value for floor heating | 5,800 |
| What should I do if the floor heating pressure gauge is inaccurate? | 4,300 |
4. How to deal with abnormal pressure
1.pressure too low: Check whether there is water leakage in the system, and replenish water to normal pressure through the water replenishment valve.
2.Pressure is too high: Release part of the pressure through the pressure relief valve and check whether the expansion tank is working properly.
3.Pressure gauge pointer does not move: The meter may be clogged or damaged and needs to be repaired or replaced by a professional.
5. Routine maintenance of geothermal pressure gauge
1. Check the pressure gauge reading regularly and record the pressure changes.
2. Keep the pressure gauge clean to prevent dust from clogging it.
3. Check the accuracy of the pressure gauge every year before the heating season.
4. If any abnormality is found, contact professional maintenance personnel promptly.
6. Suggestions for purchasing high-quality pressure gauges
| Key points for purchasing | Recommended standards |
|---|---|
| Measuring range | 0-1MPa is appropriate |
| Accuracy level | Level 1.6 or higher |
| Interface size | Match the system |
| Protection level | IP54 or above |
Through the above content, I believe you have mastered the viewing method and related knowledge of geothermal pressure gauge. Correctly monitoring system pressure is key to ensuring efficient operation of floor heating. It is recommended that users check regularly and keep records. If you encounter complex problems, please contact professional floor heating service personnel in time.
