Graphite Seal Ring
Carbon seal ring is very versatile, it is very suitable for a variety of complex working conditions and in the same series of multi-unit coal mill. It is also very convenient to install. Because large sealing rings are installed in sections, the assembly sequence is usually marked to ensure the sealing effect. The carbon sealing rings are produced by advanced technology to ensure that each section is identical, can be assembled in any order, and ensure a good sealing effect. Secondly, high temperature resistance, due to the specificity of carbon graphite materials, it can be operated stably for a long time in the environment of 400 ? (even 500~600 ?).
More wear-resistant and durable. In the case of coal powder with high impurity content, the wear rate of the carbon seal ring is relatively large, resulting in a short service life. The produced carbon seal ring can adapt to more diversified coal quality under the condition that the sealing effect is guaranteed, with longer lasting effect and better stability. And the power plant can also run stably during the normal maintenance cycle.
We have long-term reserves of ZGM80, ZGM95 series, ZGM113 series, ZGM123 series, ZGM133 series carbon seal rings for coal mills [inventory stock] see "2019 inventory schedule" for details.
Since cooperating with Beijing Electric Power Equipment General Factory in 2008, it has cooperated with relevant technicians to improve some models of ZGM series coal mill carbon refinery ring. The antimony-impregnated carbon fine sealing ring produced by a special process, the analysis of its graphite structure and performance shows that the mechanical properties of its graphite material exceed domestic similar products, reaching the international advanced level, and some indicators exceed the corresponding international standards. Some customers have undergone actual tests on site, and the longest service life reaches 10,000 hours. The difference in actual working conditions still has a certain impact on the service life.

Advantages of ZGM series carbon sealing ring
- Strong versatility. Suitable for complex working conditions, suitable for multi-unit coal mills of the same system, such as carbon ring for ZGM113 series coal mills. Suitable for: ZGM113-N, ZGM113-G, ZGM113-?, ZGM113-?, etc.
- Easy installation. Since large sealing rings are installed in sections, the assembly sequence is usually marked to ensure the sealing effect. The carbon seal rings developed by Guangxin Guoneng are produced by advanced technology to ensure that each section is identical and can be assembled in any order, and Ensure perfect sealing effect.
- High temperature resistance. Due to the specificity of carbon-graphite materials and antimony impregnation, it can be operated stably for a long time in the environment of 400? (even 500~600?).
- More wearable and durable. In the case of coal powder with high impurity content, the wear rate of the carbon seal ring is relatively large, resulting in a short service life. The carbon seal ring produced by Guangxin Guoneng Co., Ltd. can adapt to more diversified coal quality under the condition that the sealing effect is guaranteed, and last longer.
- Good stability. The power plant can run stably during the normal maintenance cycle.
ZGM series carbon seal ring installed on site
- Due to the particularity of the process, each carbon ring is exactly the same, realizing random assembling.
- Arrange them randomly in any order, just install positioning pins and springs.
- Precautions for packaging, storage and transportation
- Each ring is composed of multiple sections. The whole ring is stacked with multiple sections and covered with plastic film. The specifications and model labels are attached after the tape is wrapped. Put the spring and the positioning block together in a ziplock bag to seal the package.
- Foam is placed around the carton to prevent vibration, and sealed with adhesive tape before being reinforced by packing tape. Refer to the picture for appearance.
- If transported by SF Express (EMS, Debon), the tape is fully sealed and then reinforced by 4 packing belts (two horizontal and two vertical); special circumstances-plus wooden box full seal and metal packing belt.
- Handle with care while handling, and do not roll or throw.
