Abstract
The invention discloses a mechanical seal operation tracking early-warning protecting device. An eddy current displacement sensor (5) is mounted next to a mixing shaft (1) above a mechanical seal (2). A balancing system (4) is internally provided with a liquid level sensor (8) and a temperature sensor (7). The eddy current displacement sensor, the liquid level sensor and the temperature sensor are connected with a data receiving device. Data information which is from the sensors is finally transmitted to a programmable logic controller (PLC) (12) for processing and comparing with preset values, thereby transmitting different alarm signals according to different conditions. Personnel in a control room perform corresponding operations and a field investigation according to the different alarm signals, thereby performing tracking, pre-warning and protecting functions on mechanical sealing operation.
