How to exhaust and release water from geothermal pipes
During the use of the geothermal heating system, the heating effect may be reduced due to air entering the pipes or water quality problems. Exhaust water is an effective way to solve this problem. This article will introduce in detail the steps, precautions and related data for exhausting and draining geothermal pipes to help you maintain your geothermal system efficiently.
1. Steps for exhausting and draining geothermal pipes
1.Shut down geothermal system: Before operation, make sure the geothermal system is completely turned off to avoid burns caused by high-temperature water or steam.
2.Preparation tools: You need to prepare wrenches, buckets, towels and other tools for draining water and cleaning.
3.Find the exhaust valve: The exhaust valve of a geothermal pipe is usually located above the water distributor or at the highest point of the pipe. Please refer to the table below for specific locations:
| Part name | location |
|---|---|
| Water distributor exhaust valve | top of water distributor |
| Pipe exhaust valve | highest point of pipeline |
4.Exhaust operation: Use a wrench to slowly open the exhaust valve. A "hissing" sound indicates that the air is being exhausted. After the water flow stabilizes, close the exhaust valve.
5.Water release operation: If the water quality is turbid or contains impurities, drain the water through the drain valve of the water distributor until the water flow is clear.
2. Precautions for exhaust and water discharge
1.Safety first: Avoid direct contact with high-temperature water or steam during operation to prevent burns.
2.Regular inspection: It is recommended to check the geothermal system once a year before the heating season to ensure that the exhaust valve and drain valve are working properly.
3.water quality management: If the water quality is poor, consider installing a filter or cleaning the pipes regularly.
3. Common problems and solutions
| question | Reason | Solution |
|---|---|---|
| Exhaust valve leaking | Valve seal is not tight | Replace exhaust valve or gasket |
| Heating effect is still poor after draining water | clogged pipes | Clean the pipes or contact a professional |
4. Recommended maintenance intervals for geothermal pipes
Based on actual usage, it is recommended to perform maintenance according to the following cycles:
| maintenance items | Recommendation cycle |
|---|---|
| Exhaust | once a month |
| Release water | Every year before the heating season |
| Pipe cleaning | Once every 2-3 years |
5. Summary
The exhaust and water discharge of geothermal pipes is an important maintenance measure to ensure the heating effect. Through regular inspections and standardized operations, problems such as pipe blockage and air accumulation can be effectively avoided. If you are not familiar with the operation, it is recommended to contact professionals for maintenance to ensure long-term stable operation of the system.
