Roll-Off Cleanliness of a Hydraulically Operated System

摘要

It is always desirable to assemble any component or system with clean parts in a controlled manufacturing environment. However, this may not be possible in all situations. It is sometimes necessary that the entire hydraulic system undergo a cleanup process after final assembly to reach the desired roll-off cleanliness level. This paper provides a theoretical calculation of appropriate flushing requirements. Adherence to established roll-off cleanliness levels will provide the OEM with a better product and fewer warranty claims.
