2. Detailed explanation of the Freon filling amount of XCMG hook machine
According to XCMG’s official technical manual and industry maintenance data, there are differences in the Freon filling amounts of different models of hook machines, as follows:
| Model | Freon type | Standard filling amount (g) | Applicable ambient temperature |
|---|---|---|---|
| XG956H | R134a | 800-850 | -10℃~45℃ |
| XG836N | R404A | 750-800 | -15℃~40℃ |
| XG758E | R22 (phasing out) | 900-950 | -5℃~50℃ |
Things to note:
1. Before filling, make sure there is no leakage in the system and use a professional pressure gauge to detect it;
2. R22 models will gradually be replaced by environmentally friendly refrigerants, and users are advised to pay attention to policy updates;
3. Overcharging may cause damage to the compressor, so operation must be strictly carried out according to the standards.
3. Hotspot extension: Freon environmental protection policies and industry trends
Recently, the Ministry of Ecology and Environment issued the "Refrigerant Recovery Management Specifications" to further regulate the use of Freon in the field of construction machinery. The following are the three issues that netizens are most concerned about:
| question | Summary of official response |
|---|---|
| How to adapt the old model hook machine to the new refrigerant? | It is necessary to replace the compatible drying bottle and seal. It is recommended to contact an authorized service point. |
| Can individuals purchase Freon? | Special operation certificate required (refrigeration type) |
| Penalty standards for illegal deposits | The maximum fine is 50,000 yuan and rectification is required within a time limit. |
4. Practical suggestions for users
1.Regular testing:It is recommended to check the air conditioning system pressure every 500 working hours;
2.Choose service provider:Priority is given to maintenance points with “refrigerant recycling qualifications”;
3.Alternative:New hook machines have begun to use environmentally friendly refrigerants such as R513A, with the energy efficiency ratio increased by 18%.
Through the above structured analysis, users can clearly understand the standards and industry trends of Freon filling of XCMG hook machines. If you need maintenance parameters for specific models, it is recommended to visit XCMG’s official website to download the latest technical manual.
