You are here : Face temperature testing technology
Mechanical seal face temperature measurement methods are thermal resistance method, and non-contact infrared thermocouple measurement method. RTD temperature sensor and high precision, fast response, and thus end the measurement temperature can directly reflect the situation of the sealing surface of the friction heat. The disadvantage is the relatively low accuracy, linearity is poor, aging fast, large temperature sensitivity to the environment, and the larger, more difficult to measure. Used to measure the state of fluid lubrication of mechanical seal face temperature, the better, in the mixed friction state, the test data is less stable. Thermocouple temperature sensor can be made very small, and thus can easily be buried in a closed loop, and easy multi-point measurements. The most significant of such sensors is characterized by high precision, relative stability, the drawback is to respond as fast as heat resistance temperature sensor. Infrared thermometry temperature measurement is the use of infrared spectroscopy as a method to achieve end-temperature continuous, real-time test, but due to the surface emissivity, surrounding environment, and many other factors, the temperature measurement accuracy is usually lower than the thermal Thermocouple temperature measurement accuracy, especially the infrared camera is expensive, making it difficult to promote the use of.
TPWill using thermocouples buried in the sealing ring method, the seal face along the radial and axial temperature gradient, and close to the seal face temperature of the liquid has been measured; JCDoane buried in the sealing ring also measured the number of thermocouples Seal face temperature and its gradient; RLPhillips such as in a real pump thermocouple buried in a sealed, the seal face temperature was measured and used close to the measurement results of the numerical method to estimate the Nusselt number.
