How to test the pressure of a radiator: analysis and operation guide of hot topics on the Internet
As winter approaches, the maintenance and inspection of heating systems has become one of the hot topics recently (in the past 10 days). Many users discuss methods and precautions for pressure testing radiators on social media and home forums. This article will provide you with a structured guide for pressure testing of radiators based on hot topics across the Internet.
1. The importance of radiator pressure test
Pressure testing is a key step to detect the sealing and pressure-bearing capacity of the heating system, which can effectively avoid water leakage problems during winter use. Recent hot search data shows that the following cities have the highest attention to "heating pressure test":
| Ranking | city | search index |
|---|---|---|
| 1 | Beijing | 85,200 |
| 2 | Harbin | 72,500 |
| 3 | shenyang | 68,300 |
| 4 | Shijiazhuang | 53,100 |
| 5 | Taiyuan | 47,800 |
2. Preparations before pressure test
According to the hot discussions in professional forums in the past 10 days, the following preparations need to be made before pressure testing:
| steps | Operation content | Things to note |
|---|---|---|
| 1 | System check | Make sure all valves can open and close normally |
| 2 | Tool preparation | Pressure gauge, pressure pump, sealant, etc. |
| 3 | Time selection | It is recommended to do it 2-3 weeks before the heating season |
| 4 | security measures | Turn off the power and drain the original water from the system |
3. Pressure test standard parameters
The pressure test standards recently issued by heating companies in many places are as follows:
| System type | Test pressure (MPa) | Holding time | Pressure drop requirements |
|---|---|---|---|
| Ordinary residence | 0.8-1.0 | 30 minutes | ≤0.02MPa |
| high-rise building | 1.2-1.5 | 60 minutes | ≤0.03MPa |
| independent heating | 0.6-0.8 | 20 minutes | ≤0.015MPa |
4. Detailed pressure test steps
The pressure test process is summarized based on the popular DIY videos on Douyin, Kuaishou and other platforms in the past 10 days:
1.Water injection and exhaust: Slowly inject clean water into the system, and at the same time open the exhaust valve to discharge air until the water flow is stable.
2.initial pressurization: Use a manual pressure pump to gradually pressurize to 1.5 times the working pressure (usually 0.6-0.8MPa).
3.Voltage stabilization test: Keep the pressure under observation for 30 minutes. The allowed pressure drop should not exceed 0.05MPa in the first 10 minutes, and it should be basically stable in the next 20 minutes.
4.Comprehensive inspection: Wipe all joints and valves with a dry towel and check for leaks, paying special attention to hidden parts.
5.Pressure relief treatment: After the test is completed, slowly release the pressure. It is recommended to retain 0.1MPa pressure to prevent air from entering the system.
5. Solutions to common problems
Based on recent popular questions and answers on Baidu Zhizhi, Zhihu and other platforms:
| Problem phenomenon | Possible reasons | Solution |
|---|---|---|
| Rapid pressure drop | There is a leak in the system | Check for leaks with soapy water |
| Pressure gauge does not rise | The water inlet valve is not fully open | Check all valve status |
| Not hot locally | Air blockage or impurity blockage | Increase exhaust times |
| Water leakage from interface | Seal aging | Replace gasket or raw material tape |
6. Professional advice
1. The pressure test water temperature should not exceed 40°C to avoid thermal expansion and contraction affecting the results.
2. It is recommended that old communities contact professionals for pressure testing. Recently, heating companies in many places have provided free testing services.
3. After the pressure test is completed, a test label should be posted on the system, indicating the date and results.
4. When testing the pressure of the floor heating system, special attention should be paid to the detection of the water distributor.
7. Recent hot topics related to
1. "Who is responsible if a pipe bursts during a heating pressure test?" has become a hot topic in legal accounts
2. "Intelligent pressure monitoring system" attracts attention on JD crowdfunding platform
3. Douyin’s topic “#heattestpressurechallenge” has been played more than 8 million times
4. Heating companies in many places launch "online pressure test appointment" service
Through the above structured data and method guidance, you can complete the radiator pressure test work safely and effectively. It is recommended to save this article or collect related video tutorials for reference during actual operation. If you encounter complex problems, you should contact professional maintenance personnel in time.
