How To Lock The Leakage Of Listed Biological Enterprises, How To Break The 400mm Giant Shaft Seal?
2025-06-27
Today, we were invited to visit a large listed holding biotechnology company. Its core business is to produce high-quality protein powder, and its by-product is high-quality pet feed raw materials. The focus of this trip is locked on a key equipment-a double-shaft paddle mixer.
On-site observation found that the shaft end seal of the mixer had a serious leakage problem. The particle size of the leaked material is similar to bean dregs. Although it is not dusty, it continues to scatter, which not only causes material loss, but also runs counter to the 5S refined management (clean environment as the core requirement) that customers are strictly implementing. As a listed company, it is crucial to maintain a high standard production environment and fulfill environmental protection responsibilities.
The challenges of the working conditions are clear and specific:
Equipment speed: extremely low, only 5 rpm
High working temperature: Bag temperature reaches 150℃, actually measured temperature of shaft end 147℃
Large shaft system size: Shaft diameter 400mm, distance between two shaft ends 190mm
Material characteristics: The leakage is bean dregs-like particles
High temperature, low speed, large shaft diameter - these harsh working conditions have put forward severe tests for traditional packing seals, and are also the key factors leading to the current serious leakage. The customer's goal is clear: leakage must be completely eradicated to meet 5S and higher environmental protection requirements.
To this end, we carried out a detailed on-site investigation, accurately measuring and recording every key working condition detail throughout the process. Our professional mission is clear: to design and implement a set of high-performance rotary shaft seal solutions to achieve seamless docking and replacement with existing equipment.
Directly point to:
Zero leakage: Completely block material leakage, eliminate waste, and ensure a clean environment.
High reliability: Stable and long-term operation under high temperature, low speed, and large shaft diameter conditions.
Assisting 5S: Creating a clean and standardized production site for customers and supporting their management excellence goals.
We will use professional technology and customized solutions to safeguard the green, efficient and sustainable development of this leading biotech company!
