EQUIPMENT MANAGEMENT AND MAINTENANCE

This design allows for the selection and use of corresponding
types of process oil according to different rubber compound
formulation requirements. With the development of technology
and the deepening of application, the multi-barrel lubrication
system using thin oil has been gradually introduced into actual
production to achieve more refined management of process oil.

and accumulation of rubber compound can wear parts and
decompose at high temperatures, affecting quality. The system
injects high-pressure process oil to form a seal, reduce friction,
lower temperature to prevent vulcanization, and simultaneously
form an oil film on the contact surface to achieve lubrication,
sealing, and impurity cleaning.

3 Development trend and vision of
lubrication system
Technological innovation, green development,
and intelligence are the core issues in today's industrial
development. Against this backdrop, the evolution of the
internal mixer lubrication system has also followed this trend,
continuously moving towards green and intelligent directions.
In the future, dry oil lubrication systems will adopt multi-
pump precision oil injection to address the issue of significant
differences in oil consumption across different parts. For
Figure 7 Rotor end face seal lubrication diagram instance, there is a notable difference in oil consumption
between large and small bearings, and a single-pump system
To ensure the quality and performance of rubber
lacks sufficient adjustment accuracy, which can easily lead
compound products in the mixing chamber, and considering the
to insufficient or excessive oil injection. Therefore, multi-
