METHOD FOR MONITORING A SEALING AGENT CIRCUIT OF A DYNAMIC SEAL AND DEVICE HAVING A DYNAMIC SEAL

摘要

The invention relates to a method for monitoring physical parameters of a sealing agent in a sealing agent circuit (13) of a dynamic seal (2) of a device (1). In this case, at least one physical actual parameter of the sealing agent is determined and compared with at least one defined nominal parameter. If a deviation between the actual parameter and the nominal parameter is determined here, this deviation is used to make a prediction about an operating state of the dynamic seal (2). The invention also relates to a device (1) having at least one rotating shaft (11) which is sealed off from a stationary machine part by way of a dynamic seal (2).
