The heat conducting oil is a common heat medium in industry, and is particularly easy to cause disaster accidents. Once leaked, it can result in personal injury and loss of property. The system is greatly damaged, the contact area of leaked high-temperature heat conduction oil with air is larger, the ignition and explosion speed is higher, if the sprayed heat conduction oil is mist-shaped particles, the contact area of the sprayed heat conduction oil with oxygen is larger, and the ignition or combustion can be instantly carried out. If the heat conducting oil leaks into the heat insulating layer, the released heat is wrapped in the heat insulating layer and is not easy to be led out, so that the temperature of the heat insulating layer is gradually increased, and the heat insulating layer can cause fire when the temperature exceeds the self-ignition point. So that the leakage of the thermal oil should be taken into account. The company increases patrol intensity and is used as a key inspection area. But still does not find the first time, the first time response.
Through checking leakage points, big data shows that the leakage probability is the most that the pump end cover flange in the oil pump area is, and once exceeding service life, the oil seal graphite pad is easy to crack because of expansion with heat and contraction with cold, and then leads to the leakage situation. Timely response and timely response can be achieved by increasing leakage detection.

As shown in fig. 1 or 2, the temperature sensing alarm system for preventing heat transfer oil leakage includes a heat transfer oil layer disc 100, a plurality of thermistors (not shown in the figure) are disposed in the heat transfer oil layer disc, and the heat transfer oil layer disc 100 has a length of about 400mm, a width of about 400mm, and a height of 30 mm. The thermal oil layer tray 100 is made of metal, and a thermistor (not shown) is disposed on an inner surface or in an interlayer of the thermal oil layer tray 100.
The thermal oil layer tray 100 is designed to mainly place or set the related items required for the test. Containing the leaked heat transfer oil, a thermistor (not shown in the figure).
The thermal oil layer disk 100 is then disposed at a pump end cap flange (not shown) of the oil pump region.
This is because the inventors found that:
through checking leakage points, big data shows that the leakage probability is the most that the pump end cover flange in the oil pump area is, and once exceeding service life, the oil seal graphite pad is easy to crack because of expansion with heat and contraction with cold, and then leads to the leakage situation.
The thermal conductive oil layer disk 100 is connected to the control system 200 through a first connecting circuit wire (101 in fig. 1, 4 and 5 in fig. 2).
The temperature controller 300 is provided with a temperature display screen (not shown in the figure), and the temperature controller 300 is connected with the control system 200 through a second communication circuit lead 301.
Second pass circuit conductor 301 includes temperature sensing circuit 1 and temperature control output circuit 2 as shown in fig. 2.
The temperature of the temperature control node of the temperature controller 300 is 60 ℃, and when the environment temperature measured by the thermistor is 60 ℃ after conversion, the temperature is output through the temperature control output circuit of the temperature controller 300 to control the alarm 400 to give an alarm.
The alarm 400 is provided with a sound output alarm unit (not shown) and a photoelectric output alarm unit (not shown), and the alarm 400 is connected with the control system 200 through a third communication circuit lead 401 (7, 8 in fig. 2).
