TROUBLESHOOTING of PAPER MACHINE VACUUM SYSTEMS

摘要

All wet-laid process paper machines have vacuum systems and, generally, these operate without frequent problems. However, when difficulties occur within the vacuum system, it may be difficult to identify the actual problem or cause. Often, the symptoms get treated rather than the actual problem. This troubleshooting guide should assist mill maintenance and production personnel in quickly determining the causes of vacuum system problems, and identify the differences between vacuum pump problems and those external to the pump(s).
