Analysis of Fan Safety Monitors for Cooling Towers

Analysis of Fan Safety Monitors for Cooling Towers The purpose of the fan safety monitoring and management is to automatically detect the changes of vibration, oil temperature and oil level, and display and record them.30CrMnSiA vacuum heat treatment process At the same time, the fan whose detection value exceeds the limit will be alarmed and stopped, so as to achieve the safe and stable operation of the fan. The purpose of reducing or even eliminating the occurrence of fan damage accidents. According to the actual situation of on-site management, the three parameters of "fan vibration", "lubricating oil temperature" and "gearbox oil level" are determined to be the most important operating parameters to ensure the safety of the fan. A total of 15 design parameters such as "measurement range", "measurement accuracy" and "inspection time" have been determined for R&D and production.Atmospheric carburizing and low pressure vacuum carburizing of gears The system uses multi-parameter combined probe technology, digital command coding technology and computer network management technology. The three-parameter combination probe is installed on the fixed seat of the berth ruler of the fan gear box, and its probe rod is directly inserted into the lubricating oil, which directly converts the oil temperature, berth and equipment vibration values in the gear box into electrical signals, and transmits them to the remote control room. Fan safety monitor. Each safety monitor can be connected with 8 combined probes with a four-core cable to monitor the operating parameters of 8 fans in real time, and complete digital display at the same time. Over-limit alarm, over-limit shutdown and other multi-phase functions. After many tests and modification designs, it has been successfully applied to the equipment production site, and various parameters have reached the predetermined design requirements.Vacuum heat treatment of electrical pure iron
